It is so interesting that the new owners moved the company from a loss making one to an extremely profitable one. It was always a car that I adored for its strength. One of my friends is a fan and has had 3 different models of the Land Rover series.
This car specifically had a lot of changes made in 2007. It was almost like a reintroduction of the defender. Most of the changes were internal, the major being one to meet the emissions criteria. They changed the bonnet slightly too. Defender in general was one of the toughest vehicles in the land rover series. It was used in the British Army, Armies of Commonwealth of Nations, as police cars etc. It has been used an off roader around the world. It is one of the best off road cars to maintain. According to my understanding, with changes in the engine, people would have doubted the cars capabilities and might have started thinking of it as a lesser powerful car than its previous versions. Through this advertisement the intention of portraying it as an even more powerful car can be seen. This advertisement is mostly geared towards men between the ages of 25 to 50. It shows the aspect of immense strength to pull two heavy water vehicles much larger than the car itself. The size of the second ship is kept somewhat a mystery as they have not shown the complete ship creating a feeling that it is much bigger than it looks.
So the car is shown at the forefront of this picture so the clear emphasis on it is clear. If we study the lines in the picture we see two types, diagonal for the dock/road that goes by the water and curves of the ropes used to tie water vehicles to 2007 Defender. This shows that even within the agitation there is calm and grace by which the car is pulling the two water vehicles gently. Agitation part is also emphasized by showing a prominent dividing line between tiles and some cracks on the road.
Overall I think the ad was pretty well done but if asked if I would make changes, I would reply saying that there are two which I think should have been done differently. The skies should either be clear or stormy. Gloomy skies kill the attitude being shown slightly. Second would be to remove the birds from where they have been placed and put them somewhere over the ship. The birds do make it look more natural but where and how they have been placed make them a distraction which could be avoided. | mechanical_engineering |

September 14, 2022
The fuel injector is an important part of the diesel engine fuel supply system to realize fuel injection. Its function is to atomize the fuel into tiny droplets according to the characteristics of the diesel engine mixture formation, and inject them to specific parts of the combustion chamber, so that the engine can start normally. However, once the fuel injector fails, the engine cannot be started, which affects the normal operation of the vehicle or machinery. So how should we check whether the fuel injector is good or bad? Now Megicar Auto Parts Co.,Ltd makes a simple analysis for you.
1. Special equipment inspection: remove the fuel injector and take it to the fuel injector test bench for inspection. If the detected injection pressure fails to meet the corresponding technical standards, the atomization of the injector is poor, there is oil dripping or leakage, and the injector cannot be recovered after cleaning and adjustment, the injector is faulty.
2. Judge whether the fuel injector is good or bad by the difficulty of starting the cold engine and the exhaust smoke color after starting: it is difficult to start the cold engine, and the exhaust smoke color after starting has white smoke or black smoke. If the fuel supply angle and cylinder pressure are normal, the fuel injector may be faulty.
3. Cylinder cut-off method: After the engine is started, maintain a stable speed, and then loosen the high-pressure fuel pipes one by one to see if the engine speed changes. If the generator speed drops significantly after the cylinder is cut off, it means that the combustion of this cylinder has an effect on the engine, and the injector of this cylinder is good. If the rotation speed of the generator does not decrease significantly after the cylinder is cut off, it means that the combustion of this cylinder has no effect on the engine, and the white smoke or black smoke of the engine is less, it means that the injector of this cylinder is broken.
4. Remove the fuel injector. If the fuel injector has a lot of carbon and is wet, the fuel injector will not work well.
5. If it is found that the engine oil becomes thin and the engine oil smells of diesel, it is often related to injector failure.
Megicar Auto Parts Co.,Ltd is a professional supplier and manufacturer of common-rail fuel injector in China. We are keen to develop customers who need fuel injectors worldwide and provide our good products to Achieve long-term cooperation. | mechanical_engineering |

Garage Door Opener Repair West Covina CA
Buying a new garage door opener isn’t simple. It’s not as easy as running into your local supermarket to pick up a few things for dinner. You have to think about all of your needs and the requirements of your garage. You have to ask yourself things like: How large does my garage door have to be? Does my garage hold one or two cars?
In addition, there’s a multitude of garage door openers to pick from. When deciding on a new opener it’s important to consider it’s compatibility with your garage door. A select number of openers pair flawlessly with certain doors. While other openers will constrain, or even handicap, the function of some garage doors. If you don’t have professional training, you might have difficulty matching openers with their corresponding doors.
That’s why you should seek the help of garage door experts. The technicians at our company have extensive knowledge of virtually all the makes and models of every garage door and opener on the market. They’ve handled almost every situation imaginable. Furthermore, their suggestions and insights are based on years of experience.
Garage Door Opener Sensors
Garage door photo-eyes, or sensors, trigger the safety reverse mechanism that is a part of almost every garage door opener system. When vehicles, animals, or people breach the sensors’ light beam the auto reverse halts and then retracts the door before it can damage property or cause bodily harm.
Broken, dirty or misaligned photo-eyes can cause garage door openers to malfunction. This can compromise the garage door’s ability to close. More importantly, however, it can put you, your pets, and your loved ones at risk of danger.
Our certified technicians can troubleshoot these problems and much more. Their broad experience and expertise give then the know-how and confidence to tackle any situation involving garage door sensors. They work with the top garage door opener manufacturers like Marantec, Chamberlain, Liftmaster, Genie, and Craftsman.
We do garage door opener installations, too. A garage door only works well if the door opener is put in, correctly. You can trust us not to compromise on the quality of our products or excellent service!
Below are the most popular styles of garage door openers that we install.
Belt Drive Openers
These garage door openers produce less noise as compared to other openers. This is because their motion is driven by rubber belts. Besides making these openers virtually noiseless, this unique technology increases the longevity your garage door. They are more expensive, however.
Screw Drive Openers
Screw Drive Openers use a threaded rod to direct the movement of the garage door. It has less moving parts, and because of this fact it requires less maintenance.
It is, however, sensitive to drastic switches in weather. Extreme element changes can compromise its perform.
Chain Drive Openers
Chain drive openers are durable and strong. They are excellent for lifting heavy doors. When you compare it with other garage door openers you will find that chain drive openers are less expensive and more reliable.
They are noisy, however. Their noise pollution can be heard in nearby bedrooms and attics.
These garage door openers are a great choice for homeowners who want more storage space and garages with low ceilings. This is due to the fact that these openers are mounted on the wall of the garage as opposed to above the garage door entrance.
They are powered by DC power and have a long lifespan, as well.

I had stopped to take a photo of the red Hanjin ship along the Embarcadero. Then I continued to ride and noticed the front brake pads securing the wheel had come off. I got off and managed to barely secure the hook again. Then that’s when my little accident occurred.
Instead of looking ahead I looked sideways to see if a nearby bike shop was open. Unfortunately I rode straight into the short steel posts and landed on my side.
A man sitting on the bench in front of the Hi-Dive bar rushed to ask if I was OK and help me land on my two feet again. Just a slight bruise on one side of my knee but overall I came away with just some minor bruises.
So I asked the man to help my get the front brake secured on my bike again. The fall had twisted the brake hook. So while he got to work trying to disconnect the hook and unravel the twist I started chattering away about how I just came from South San Francisco and this bike is my only mode of transportation.
He asked out of curiosity what I did for work. I replied “logistics,” as in ocean transportation. It turns out he used to work in shipping a bit himself. He was based in Guam at the time when he arranged some domestic shipping, drove some trucks and generated bills of lading.
I was so excited he spoke my “language” and knew about the biggest player in the South Pacific shipping route – Matson Logistics. I went on to explain how Matson took the concept of the container and enhanced it through research and finally came up with a concept that optimized the entire shipping business. We parted ways but not before I asked to take his photo. I love these little random run ins. The world of shipping is quite small. | mechanical_engineering |

To gain a thorough understanding of the current facility, the following background information will be collected:
Upon receipt of this information, MMM Group will analyze the utility bills for the previous two years in parallel with the most recent facility drawings available. The drawings will be used to determine building design factors contributing to energy use. Floor area, occupancy, and space usage will be verified and used to gain a better understanding for the factors that affect energy use.
After completing the energy benchmarking and documentation review, they will visit the facility to meet with the project and operations team and walk through the building to confirm our initial assessment, gain an understanding of building systems and operational characteristics and answer any outstanding questions from the benchmarking exercise. During this visit, we will note any specific noticeable energy items in the operation for “process” energy consumption and discuss the operation with the owner/operator to gain a better understanding and identify items to include in energy model.
Using the information collected they will create a “baseline model” representing the building as currently operating. Where information is unavailable, the model of the building will include energy modelling assumptions (e.g. installed lighting power density, single zone rooftop units, etc) reflecting current retail industry practice.
A “net zero model” reflecting facility building systems with all agreed upon energy conservation measures installed and operating as designed will be created. The approach to reducing the energy consumption of a building starts with conservation before considering more efficient energy production and/or procurement. To create a net zero retail building they will address energy efficiency measures in the following order:
Based on the energy modelling results they will estimate the capital cost and operating cost savings for the net zero building scenario.
They will complete an assessment of the life-cycle impacts for the net zero building including embodied impacts and building and process energy use. Life-cycle cost will also be provided as part of this analysis. | mechanical_engineering |

His group is strongly interdisciplinary, combines computational and experimental work, and currently involves 5 PhD students and 5 postdocs. Computational models relate to the use of mesh-based and meshless (particle-based, agent-based) methods and study cell-matrix mechanics and angiogenesis, and its relation to tissue regeneration. Experimental work aims at quantifying cell-matrix mechanics and solute transport, among others by means of optical microscopy imaging and image data analysis. Challenges relate to integrating computational and experimental data to generate novel understanding on cell-matrix mechanics and angiogenesis. Hans Van Oosterwyck has been a Council Member of the European Society of Biomechanics (ESB) since 2006. He has been the President of the ESB between 2012-2014.
“Quantifying cellular forces during endothelial cell migration and vascular invasion”
Angiogenesis, the formation of new blood vessels from the existing vasculature, is a process that is fundamental to tissue and organ development, growth, repair and disease. Numerous studies have focused on the biochemical regulation of angiogenesis. In contrast, studies that target the mechanical regulation of angiogenesis are rare. In our group, we develop experimental and computational tools to quantify cell-matrix mechanical interactions and to investigate their importance for angiogenesis, both at the single cell scale as well as multicellular scale of an invading angiogenic sprout.
In vitro model of single endothelial cell adhesion and migration
Endothelial cells were cultured on soft polyacrylamide hydrogels of different stiffness values (1.4, 2.7, and 4.5kPa) and coated with different adhesion proteins (fibronectin or collagen). Cellular tractions were quantified by means of Traction Force Microscopy (TFM). Two spatiotemporal analysis methods were implemented and applied to the TFM data. A first analysis zooms into the acquired traction maps and define subsets of tractions associated with a local single peak of maximal traction, termed traction foci, in this way analyzing tractions at a subcellular scale close to the length scale of focal adhesion complexes. A second analysis clusters cells based on spatial distribution, magnitude, and temporal evolution of tractions at each time-point into distinct transient states. These states characterize cell mechanical behavior in terms of force polarization and strength.
Traction foci were found to be larger in cells on collagen than on fibronectin, and stronger on stiffer hydrogels. The trends with which tractions increased with stiffness were different for foci and whole-cells, and depended on the adhesion protein used. Differences could be explained from the number of foci and their average strength. On fibronectin, a large number of short-lived weak foci were noticed, together being responsible for up to 30% to the total traction.
Clustering analysis demonstrated that in all conditions, cell traction exertion is polarized, particularly on collagen. By looking into state transitions it was found that cells do not easily change simultaneously their force polarization and strength.
In vitro model of vascular invasion
Displacement fields around an angiogenic sprout that invades a collagen hydrogel were characterized in relation to sprout morphology and dynamics. Collagen displacement calculations were performed by means of a B-spline-based 3D non-rigid image registration process that warps the image of the deformed gel to the image of the relaxed gel. The latter was obtained by disrupting the cell’s actin cytoskeleton. We found that maximum displacements are of the order of 2 to 10 µms and are located at the sprout tips as well as sprout bases. Between bases and tips, traction-induced matrix displacements become negligible, suggesting that single sprouts mechanically behave as a force dipole along the sprout axis. By downregulating actin polymerization with cytochalasin D, displacement magnitudes were reduced, which also influenced sprout dynamics at different length scales: total sprout invasion length and individual sprout dynamics were reduced and sprout protrusions were found to retract.
In silico models of cell-matrix mechanical interactions
Two different models were implemented that capture a mechanically active cell in either a 2D or 3D environment, by using meshless, particle-based methods. A first model describes a three-dimensional cell on a planar substrate, and captures the dynamics of cell protrusion, adhesion and stress fiber formation by means of the discrete element method. A second model makes a 2D representation of a cell embedded in a viscoelastic, degradable extracellular matrix (ECM), modeled by means of smoothed particle hydrodynamics. Protrusions follow from local reduction of cortex stiffness and the application of small protrusive forces, and stabilized through adhesion formation. Curvature-dependent cortex contractility is implemented as well, leading to cellular tractions.
Model sensitivity focused on the effect on traction polarization, morphology, and cellular traction magnitude of parameters accounting for protrusion, adhesion, actomyosin contraction, ECM stiffness, and ECM degradation. Simulations are compared to TFM experimental results. Results among others suggested that long-range deformations, as observed experimentally around invading sprouts, require collagen hydrogel to strain stiffen.

Origninally it had only two barrels and a crank loaded and fired each barrel in turn.
He needed finance to produce it, however, so went to the newly formed Pratt and Whitney Company. Francis Pratt had worked for Colt and had a reputation for being one of the top gun designers working.
Mechanism of the original two-barrelled version.
It was developed in conjunction with Pratt and Whitney but despite successful trials from 1875 until 1879 the US Army declined to buy the gun, as they felt it was not an appropriate weapon for their only military activity at the time, against the plains Indians.
Inside the crank case for the five-barrelled version.
The Royal Navy, having already bought the Gatling Gun, were more interested, however and Gardner was invited to England to demonstrate the gun, which by now had a five barrel version as well.
The two-barreled version on board ship.
The Admiralty were impressed enough that they not only adopted the weapon but bought the rights to produce it. Gardner stayed in England to supervise the construction of the weapons in Leeds and lived there for the rest of his life, dying in 1886. The British Army bought the gun in 1880 but its actual introduction by them was delayed because of opposition by the Royal Artillery.
The gun was light, reliable and could fire over 800 rounds a minute. | mechanical_engineering |

What is known so far.
French automaker Renault announced an electric car manufactured in Europe for less than 20 thousand euros. The Legend small car for urban transit is scheduled to hit the market in 2025, Renault’s newly founded electromobility subsidiary Ampere has announced.
In addition to the low purchase price, Renault promises a very low standard consumption of 10 kWh per 100 kilometers for the Legend. With its concept, the new low-cost model should succeed the traditional city car Twingo, whose current generation has been on the market for almost ten years (since 2014) and shares the technical basis with previous Smart models.
Renault is planning an electric offensive
Renault wants to offer an electric car for 25 thousand euros next year, the R5. It will be produced in northern France and, in terms of vehicle segment, is the successor to the electric Zoe. The design of the R5 has a retro look and cites the small car of the 1970s and 80s. A year later, the R4 will hit the market in SUV format.
The three models are developed and marketed by Ampere, but operate under the Renault name. The brand wants to have a total of seven electric models on offer by 2031. The goal is to sell 300,000 electric cars in 2025, and the number is expected to increase to one million by 2031. That would be half of the total cars produced.
This is the subsidiary of Renault Ampere
French car manufacturer Renault plans to IPO its newly founded electric car subsidiary Ampere next year.
Ampere employs more than 11 thousand people, a third of whom are engineers. Production takes place in three existing factories in the north of France – in Douai, Maubiege and Ruitz.
The initial production capacity of 400,000 vehicles is expected to grow to one million by 2031. Sino-Japanese manufacturer AESC Envision and French start-up Verkor, which operate gigafactories near the Ampere plant, will supply batteries.
Electric car prices are expected to fall
“We want to democratize the electric car in Europe,” said Renault’s financial director, Thierry Piéton. In the medium term, list prices for electric cars are expected to fall by 40 percent compared to current ones, and price parity with vehicles with combustion engines is expected to be achieved by 2027/2028 with the second generation Mégane E-Tech Electric and Scénic E. -Tech Electric with the same margins.
Other manufacturers are planning this
The race for affordable European-made small cars is gaining speed: Citroën launched the ë-C3 small car for 23,300 euros in October. The small car with SUV proportions and a range of 320 kilometers will be available for purchase from spring 2024 and will be built at the Stellantis factory in Slovakia. A 19,900 euro variant with a weaker battery and a range of 200 kilometers will be launched in early 2025. Read more about the Citroën newcomer here.
VW boss Oliver Blume recently confirmed that the group intended to launch an electric car on the market “in the region of 20,000 euros”. However, a decision has not yet been definitively made. The ID.2 will initially come in Polo form in 2025 (you can read more about it here) – probably also in an electric GTI variant. Tesla could follow suit soon after with a cheap German-made Model 2.
Affordable electric cars are rare
Also on Tuesday, ADAC criticized the fact that it is still difficult to get a cheap electric car in Germany. Currently, there are only three models under 30,000 euros – all with a very limited range: Dacia Spring (from 22,750 euros), electric Renault Twingo (from 28,000 euros) and the Fiat 500e (from 29,990 euros ). | mechanical_engineering |

- Hay is made very carefully. There’s a surprising amount of science and engineering that goes into making hay, and now that I live in hay-making country I thought it prudent to learn more about how hay is made.
Of course, many factors contribute to the quality of hay.
- You have the type of hay, the soil it’s grown in, how “weedy” the fields are, how much rain happens (or not), and how it’s turned from grass into bales of hay. When all of the stars align, your horse can munch down on some amazing hay.
First things first – the cutting of hay.
- Basically, the hayfield is mowed using a mower-conditioner. The best time is when the grass is mature, but not old. The mowing needs to happen when there is a window of three to five days AFTER when the hay can dry. Wet hay is a mold party waiting to happen.
- When the hay is cut, the mower conditioner cuts the grass, which then goes through the conditioner to crimp the hay. This makes the drying process a little faster. Most mower conditioners will crimp the hay every 4 inches, but some super mower conditioners crimp the hay at smaller increments to speed up drying.
Windrows of drying hay.
The mower-conditioner machine also creates those rows of cut grass in the fields.
- These are called windrows, and the mower conditioner determines how wide the windrows are.
- If you need to, you can then come over the windrows with a tedder. This handy machine spreads out the windrows. To speed up the grass drying process. Must outrun the rain!
- A few more steps – if the windrows have been spread out by the tedder, then the rake can come along and put them back into windrows. Alternatively, the rake can turn over the windrows if they were not spread out by the tedder.
The tedding machine – all about helping the cut grass dry.
Now it’s finally time to bale the hay.
- The baler sucks up the windrows, and creates bales or round bales.
- Different balers create different sizes of bales. It may be a two-string, a three-string, or a baby-sized round bale, or a monster round bale.
A baler. This one creates small round bales.
There’s quite a lot of land, equipment, and dodging weather for this to happen. And, it can just as easily be ruined with the wrong timing or busted equipment.
Do you know where your hay comes from? | mechanical_engineering |

What took half a day in the past can now be accomplished in less than an hour. One of these technological breakthroughs is the convergence of CCTV and surveying, the result being portable video inspection equipment like the Pearpoint Flexiprobe pipe camera we use at Wetwork Plumbing.
Below you’ll find out more about challenges facing the construction and maintenance industries, how our Wetwork Plumbing pipeline inspections work, who can benefit from as-needed inspections, and how to book a drain or pipe inspection in Durban and Johannesburg:
Most metropolitan utilities, such as water pipes and drainage systems, are found just a few feet below the ground. The world would look like a completely different place if we didn’t bury pipes and drains! The issue with sub-terranean utilities is that finding faults when something goes wrong can be a challenge. Many a back yard have been churned up in the search for water pipe leaks and other pipeline issues.
Time is money in the maintenance and construction industry, and finding faults can sometimes take the better part of a day. Not only do workers have to physically access the pipeline, which is often in hard to reach locations, but they also need to inspect every inch of the pipe manually until the fault is found. Luckily, technology has made this a whole lot easier.
Wetwork Plumbing bridges the divide between traditional plumbing and inspection technologies, offering professional pipeline inspections with state-of-the-art UK-manufactured portable CCTV equipment. We’re able to send a probe into any conduit ranging from 70mm to 300mm in diameter – be it a drainage system or a water pipe – and assess the situation. This frees up your time and resources to focus on fixing the fault without unnecessary inspection delays!
Wetwork Plumbing, with branches in Durban and Johannesburg, is uniquely positioned to assess and document pipe faults for any industry in South Africa. We charge no call-out fees, and we won’t charge you for a quotation! Got a fault you’re struggling to find?

What hurricane protection products do you provide?
We can install steel or aluminum panels, accordion shutters, roll down shutters, colonials, and Bahamas.
Can you explain what metal hurricane panels are?
They are metal corrugated panels that can be made of galvanized steel or aluminum. They are usually 14 to 14½ inches wide and as long as building code allows in order to fit the specific opening.
How are they stored?
They can be stored stacked, usually in a garage, usually against a wall or flat on the floor.
How are they installed in my residence?
There are two basic methods of installing panels. The most economical is the so called Direct Mount Method. We install anchors in the wall that accept a threaded bolt so that its head sits flush with the wall (the part of the head that shows can be painted over to disguise it). When the Tracking Method is used, we install tracking which is usually permanent but can be made removable.
How would I put them up?
With the Direct Mount method, the person who is putting them up needs to use a power tool to unscrew each of the bolts and once the panel is hung up then it is secured by screwing the bolt back in. With the Tracking Method, they are usually inserted into an upper inverted-U shaped track and at the bottom they are secured with a Studded Angle (this is an L-shaped angle that has studs in it). The panel has holes that the stud from the angle goes through and the panel is then fastened with a wing nut — so no tools are needed in this method of installation.
What colors do the tracks come in?
The tracks can be white, bronze or mill finish in color.
Are they recommended for use on second stories?
They're not recommended for second stories or if you need to get on a ladder to put them up.
What are Accordion Shutters?
Accordion Shutters are typically made of 4 to 6 inch blades that are hinged so they can fold like an accordion (hence the name). These hinged blades slide sideways alongside tracks so that where they meet they usually lock. The folding blades are fit into a frame that is custom cut so it wraps around the outside of the specific opening. What provides strength to the Accordion Shutters is the top and bottom attachments — there is practically no limitation to their width.
Are they easy to operate?
On a first story, they are usually installed with most of the locks to the outside and as many doors as possible with the locks toward the inside. They generally slide as easily as a sliding glass door does. On a second story, they can be installed if you have single hung windows or sideway sliders or sliding glass doors. Sometimes, they can be installed even with louvered windows. Please inquire.
What Accordion brands do you use?
There are many accordion shutter products on the market, and we use the best quality product available. We provide our customers with as expedient an installation as possible under present demand conditions.
How long is the waiting time to installation?
At present we estimate that generally we can do an installation within four to six weeks after a permit is obtained. Accordions are available in white, ivory, beige and dark bronze. However, please inquire as to color availability.
What are Roll Downs?
Roll Downs are formed by joined aluminum extruded slats that run vertically up and down along two vertically installed side tracks. What gives impact resisting strength to the Roll Downs are these vertical tracks -they are installed along the outer edge of the opening. Depending on the size of the roll down, they can be either manually operated with a crank handle or with an electric motor. They roll up into a metal box that sits at the top of the opening.

Stainless steel is known and highly sought after for its durability and strength. It is a material that does not rust or fade, and can be used daily, in any type of activity or environment.
In addition to these characteristics, stainless steel also has anti-allergic properties, which makes it the perfect solution for those with sensitive skin.
Despite being easy to maintain, steel, like any other metal, requires maintenance care. If you understand that your piece is dirty and needs to be cleaned, just use a soft cloth or sponge, warm water and neutral detergent. If your piece has some detail or texture, you can replace the cloth or sponge with an equally soft toothbrush.

The author is trying to explain the amount of force required to overcome the weight falling down and then accelerate it upwards. The 275lbs was given as an example of an amount of force used to overcome a 135lb weight. The force you apply has to be greater than 135lbs because you decelerate the bar and then accelerate it upwards. For simplicity, if you applied constant force, which results in constant acceleration applied to the weight, the time it takes to travel a certain distance can be calculated. You can use the equation below assuming constant force/acceleration:
(Force - Weight) = acceleration x mass = (2 x distance)/(time^2) x mass
Using the author’s example, lets say you applied a 275lb force (1223.3N) to overcome the 135lb weight (600.5N) over a length of 0.5m from the bottom position to the top position of a clean. We’re able to calculate exactly how long it takes if we assume constant acceleration:
(1223.3N - 600.5N) = (2 x 0.5m)/(time^2) x (61.23kg)
=> time = .3136 seconds
You can manipulate the equation however you like to solve for one variable. All the author is saying is that it requires more force than the actual weight to overcome it’s inertia or momentum and accelerate it. If you had a 135lb weight and picked it up slowly, you would apply less force and generate less power in comparison to if you picked it up as quickly as possible. It sounds like the underlying message the author is trying to get across is that you control how much force you generate and it is not equal to how much weight is on the bar. You could apply the concept of maximum power output to your training. I remember reading an article in the past couple years about some device that could be attached to a barbell to measure power output. That way, it doesn’t really matter how much weight is on the bar, only that you’re training for peak power. | mechanical_engineering |

We’d never been to Wayne LaPier and Family Maple Sugar House before, and we’d just come from a pancake breakfast at another maple farm. But the woodpile stacked to the side of the building suggested that LaPier’s was an old-fashioned operation, one that still ran on wood for fuel rather than gas or electric. And a sign out front advertised an open house.
Inside we met Wayne LaPier, 75 years old, who has run this operation since 1985 when he bought it from his father. He’s standing next to the evaporator, the key piece of equipment in making maple syrup, and the producer of the smoke and steam that alerted us a boil was taking place.
Sap used to be collected in wooden or metal pails and then carried to the syrup house. Now a system of plastic tubing connects the trees and gravity carries the sap down to a drum for collection.
Those drums are gathered when they fill, brought to the syrup house, and poured into a larger collection tank.
Sap from nearby trees bypasses the collection drums and is pulled directly into the sugar house via a simple vacuum system hidden in a back closet.
In another closet sits this reverse osmosis machine. It takes the sap from the collection drums and vacuum system and rather like a household water filter, separates the water from the impurities – except in this case it’s the “impurities” that become the syrup. The process cuts the fuel needed for running the evaporator by two-thirds.
After going through the RO system, the syrup is stored in an overhead vat and gradually drained into the evaporator. Wayne bought this evaporator when he took over the operation in 1985. It’s made by the Canadian company Dominion & Grimm. Matthew Thomas’s Maple Sugar History blog has a short history of the firm, including an advertisement from 1909 with an evaporator that looks very much like this one.
There’s a pile of wood ready to be burned.
The rest of the family is moving the wood into place…
…so Wayne can keep the fire going.
Sap boils inside the evaporator, further reducing the water content.
Wayne uses a hygrometer to test the syrup from the evaporator. When the syrup reaches a particular density, it’s nearly ready for consumption.
It only needs to run through a series of filters…
…and the result is fresh, warm syrup, with a flavor much richer than even good syrup that has been packaged and stored.
Reader, should you ever have the chance to drink hot maple syrup right from the evaporator, please, do not pass it by.
Thanks to Wayne LaPier, Christine, and the rest of the family for letting us stay for an hour, answering all our questions, and giving us a taste of the syrup at its best. | mechanical_engineering |

over the cushion surface and encourage correct seating posture.
The solution is to have a seat cushion with varying hardness. Where the pressure is higher, the cushion is softer, thus
allowing more even distribution of your weight. The firmer areas discourage shifting the body forward to the front of the seat resulting in poor posture.
Through extensive in-house tests the empirical data proves that ergo-Sit technology minimises the pressure points
on the buttocks area.
Figure 1. shows pressure distribution of a seated person on an ordinary task chair cushion. The maximum pressure
is 89mm of mercury (120Kpa or 1.2bar). The standard deviation is 22.4mm of mercury.
Figure 2. shows pressure distribution of a seated person on an ergo-sit cushion. The maximum pressure is 64mm
of mercury (86Kpa or 0.86bar.) The reduction in maximum pressure on the buttocks is approximately 30%.
The diagram also reveals a much more even distribution of the weight leading to increased levels of comfort when using

Drain your water heater: Over the course of a year, hard water sediment tends to collect at the bottom of your water heater tank. The sediment deposits reduce the efficiency of your heater, costing you money!
To drain your water heater, first turn off the water supply and power to the water heater. Next, connect an ordinary garden hose to the outlet spigot near the bottom of the water heater tank. If possible, drain the water into a sink, tub, or floor drain. (Pumping the hot water outside is likely to kill your grass due to the temperature of the draining water.)
2. Sharpen and clean your garbage disposal all at once: Put a few ice cubes into your disposal and run the unit, this will quickly clean and sharpen the blades, all at the same time!
3. Change your furnace air filter: Experts recommend changing your furnace filter once a month. If you haven’t done it in a while, there’s no time like the present!
Using cheap fiberglass filters is actually preferred as opposed to more expensive HEPA filters for two reasons: First, replacing the more expensive filters every month can be costly. Second, the fiberglass filters actually allow for more air to flow into your unit reducing the amount of energy needed to effectively heat or cool your home.
4. Toilets: Water leaking from your toilet tank will not only cost you money when it comes to your utility bill, but it can also cause water damage to your bathroom floor and premature wear of your toilet’s internal workings. To find out whether your toilet tank is leaking, add some red food coloring to the water in the tank. Come back in about an hour and see if the water in the bowl is pink. If it is, you have a leak. If you find that your toilet is leaking from the tank to the bowl, the flapper needs to be replaced. To do this, simply turn the water valve located directly behind the toilet. Remove the tank lid and flush the toilet in order to empty the tank. Use a towel or sponge to mop out any excess water left in the tank. Remove the flush chain from the lever, and then slide the old flapper up off the overflow tube. Slide the new flapper in place over the overflow tube, reconnect the chain, and turn the water supply back on.
5. Faucets: The main cause of leaky faucets is worn out washers. The washers inside of the faucet handles are rubber and tend to wear out quickly. Replace them by turning off the main water supply, unscrewing the leaky handle that controls the flow of water to the spout, removing the old washer, and dropping in the new one.
6. Washing Machine & Dryer: It is important to regularly inspect your washing machine water supply hoses for leaks. One of the top reasons for insurance claims is for water damage caused by leaky washing machine supply lines. Inspect washing machine water supply lines at least annually and replace them every three years if they are plastic. If you notice that the metal ends of your water supply lines are discolored or rusty, replace them immediately.
Faulty washing machine drain hoses are as important as water supply lines when it comes to keeping water off of your floor and in your drain where it belongs. As with supply lines, regularly inspect the ends of your washing machine drain lines for discoloration or rust, and replace them immediately if you find evidence of leaking.
Additionally, check the snugness of the drain lines by using a crescent wrench or a pair of pliers. You should not be able to tighten the line any further if the line is properly tightened.
When it comes to your dryer, it is important to make sure that you regularly clean your lint screen! Not only will a clean lint screen prevent fires, but it will also increase the life of the heating element. Physically remove the lint from the screen between each load of laundry. Also, be sure to remove fabric softener residue by washing the screen with warm water and dish detergent once per week.
7. Plumbing: In order to keep water flowing freely through your pipes, keep the following things in mind:
Never pour fats or other oils down your drains. This includes oils that are not solid at room temperature. If you accidentally spill oils or fats down the drain, run hot water down your drain along with a healthy serving of dishwashing liquid. The soap will emulsify the fat or oil and move it on down the pipe, preventing a clog.
Get a hair strainer for the bathtub drain. If fats and oils are the main source of clogs in the kitchen, hair is the primary culprit in the bathroom. If you have a strainer, make sure that you remove any accumulated hair from it following each shower. This will reduce the amount of hair that finds its way through the strainer and into your plumbing.
Skip the Drano. Though the acids it contains can help unclog a drain, they also cause significant damage to your plumbing, including premature leaking. If your bathtub or toilet is completely clogged, use a small drain snake – which you can purchase at any hardware store – to pull the offending clog to the surface. If your kitchen sink is clogged, try plunging it before trying to snake the drain. If you cannot remove the clog using a drain snake, call a professional.
8. Air Conditioning: Air conditioners are among the most overlooked appliances when it comes to performing regular home maintenance. However, they can be one of the most costly appliances to repair.
Regularly inspect the condensation hose to make sure that water can flow freely from the line. If there is standing water where your condensation line drains, create a drainage path using a small garden trowel and line the path with gravel to keep mold and algae from forming, which can be a serious health hazard when the spores are drawn into the appliance and blown into your home.
Additionally, keep the screen around your air conditioner free from debris to keep air flowing easily. This will prevent your air conditioner from using more power than necessary to keep your house cool and keep the internal parts from wearing out too quickly.
9. Humidifiers: Some climate control systems have in-duct humidifiers that help keep air moist and healthy during the winter when artificial heat systems are in use. But when these systems aren’t working properly, they become a breeding ground for mold and bacteria, which can cause serious air quality issues.
At the end of each winter season, it is important to drain the unit and close the water valve to keep water from stagnating in the system. Also, cleaning the reservoir with a mixture of water and white vinegar helps to keep mineral deposits to a minimum.
10. Refrigerators: The main component of your refrigerator that should get your attention is the door seals. Keeping your door seals tight will reduce the amount of energy it takes to keep your food cool or frozen, but will also keep your refrigerator working efficiently, preventing premature wear on internal parts.
To test the door seals, close the door on a dollar bill and attempt to pull it out with the door closed. If you cannot easily pull the dollar bill out from the door, your seals are in good shape. However, if the bill slides out without much resistance, it’s time to replace the seals. You can purchase new seals from any home repair outlet store.
Also, if you have a refrigerator that has coils along the back, periodically vacuum these coils to remove dirt and dust build up. These coils contain the coolant the refrigerator uses to keep the internal temperature cold. If they become dirty, they won’t work efficiently and your refrigerator may stop cooling altogether.
As a general tip, keeping your refrigerator full uses less energy than trying to cool when it’s empty. Therefore, keep as many items in your refrigerator as possible to help reduce energy costs.
11. Drafty Windows: Drafty windows are a major culprit of high energy bills in the summer and winter months. Periodically check the condition of the caulk line that holds your windows in place. If the caulk appears to be dry, cracked, or otherwise weathered, remove the old caulk with a box cutter or other sharp knife and run a new bead of caulk along the seam.
For added utility bill savings, you can further insulate your window by applying an insulating window film over the glass. These methods cost much less than the price of replacing your windows and implementing green energy technologies in your home.
12. Gutters: While gutters may go practically unnoticed when you look at your house, they are the main line of defense between your foundation and siding and the elements. Gutters are designed to capture water and debris runoff from your roof and divert it away from your foundation, and one of the main causes of water accumulation in basements is a lack of gutter maintenance and proper water diversion.
Clean your gutters at least once per year by physically removing debris from the channels and rinsing them thoroughly by using a garden hose. Avoid installing gutter guards – not only do these not adequately prevent debris from entering your gutters, they also make it extremely difficult (if not impossible) to properly clean your gutter system.
Also, be sure to regularly check that your gutters are properly affixed to your fascia boards, and replace any sections that appear to be damaged or leaking.
13. Roof: Periodically check your roof for damage. Damaged, discolored, or gravel-less shingles should be quickly replaced to prevent the need to replace your roof, water-damaged trusses, or drywall when you finally discover a leak. During the inspection of your roof, pay special attention to shingles that surround skylights, vents, and chimneys, as these areas are the most leak-prone.

So you’ve just moved into your nice new home. You’ve unloaded the boxes and started to unpack your life.
Right now is the perfect time to walk through a checklist of ways to save money on your home for years to come.
Starting on these things as early as possible will allow you to start saving money sooner rather than later. Plus, some of them will be easier to accomplish before you hang pictures or get too settled in — and lose your move-in momentum.
Here are 19 things to check or do immediately that will reduce the energy and maintenance costs of your home over the long haul.
1. Check the insulation in your attic – and install more if needed.
If you have an unfinished attic, pop your head up there and take a look around. You should see insulation up there between the beams, and there should be at least six inches of it everywhere (more if you live in the northern part of the United States).
If there’s inadequate insulation up there – or the insulation you have appears to be damaged – install new insulation. Here’s a great guide from the Department of Energy on attic insulation, including specifics on how much you should have depending on where you live. Many states offer financial incentives, up to a 75% refund, for instance, to encourage homeowners to better insulate their homes.
2. Lower the temperature on your hot water heater down to 120 degrees Fahrenheit (55 degrees Celsius).
This is the optimum temperature for your hot water heater. Most people don’t use water hotter than 120 degrees — indeed, water hotter than that can scald you or a child — and thus the energy needed to keep the water above 120 degrees isn’t used effectively. Lower the temperature, save money on your energy bill, and you’ll never skip a beat.
3. Toss a water heater blanket over that hot water heater as well.
While most modern hot water heaters are well-insulated, some are insulated better than others, and many older heaters aren’t insulated well at all. A small investment in a blanket for your water heater will slowly and gradually save you money on your heating bill over time by keeping the heat in the water instead of letting it disperse slowly into your basement or utility closet.
The Department of Energy recommends being “careful not to cover the water heater’s top, bottom, thermostat, or burner compartment.” And of course, on-demand (or “tankless”) water heaters don’t require this treatment.
4. Install ceiling fans in most rooms.
Ceiling fans are a low-energy way to keep air moving in your home. Because of the air circulation effect, you can get away with keeping your thermostat a degree or two higher in summer and a degree or two lower in winter, netting a rather large saving.
A while back, I wrote a guide to maximizing ceiling fan use. The most important thing to know is that the air directly below the fan should be blowing down on you in the summer and should be pulled upwards away from you in the winter — you can use the reversal switch on your fan to switch between the modes at the start of each season.
5. Wrap exposed water pipes with insulation.
Exposed hot water pipes lose heat as they move water from your heater to your faucet or shower. Wrapping them in pipe insulation, especially in cold basements or garages, can make a two- to a four-degree difference in the temperature of the water, and also allows hot water to reach your faucet faster.
Check the pipes into and out of your hot water heater first, as the first three feet out of the heater (and the last few feet of inlet water) are key. Use good-quality pipe insulation for the job, which is actually quite simple — here’s a tutorial.
6. Install a programmable thermostat – and learn how to use it.
A programmable thermostat allows you to schedule automatic increases and decreases in your home’s temperature, saving money on cooling in the summer and heating in the winter.
They’re easy to install and easy to use, especially if you keep a fairly routine schedule. Just program the thermostat to drop a few degrees at night while you’re sleeping or off at work during the day, and set it to return to your preferred temperature just before you wake up or return home from work. You won’t notice the difference — until you see your lower utility bill.
7. Replace your air filters.
When you first move in, you almost always need to replace the air handling filter or the filter on your furnace or AC unit. Don’t worry, it’s easy to do – it takes about 10 seconds.
Go down to your air handling unit, find where the filter is (it’s almost always a large rectangle), and mark down the measurements (printed around the edges). Then, go to the hardware store and pick up a few of them. Go home and replace the old one with a new filter, and save the rest so you always have a clean one ready to go. An outdated filter not only doesn’t filter air as well, but it also has a negative impact on air flow, meaning your air handling system or HVAC unit has to work harder — and use more energy — to pump out lower quality air.
8. Make sure the vents in all rooms are clear of dust and obstructions.
None of the vents in your home should be covered or blocked by anything – doing that makes your heating and cooling work overtime. You should also peek into all of your vents and make sure they’re as dust-free as possible, and brush them out if you see any dust bunnies. This improves airflow into the room, reducing the amount of blowing that needs to happen.
9. Mark any cracks in the basement with dated masking tape.
Many homes have a few small cracks in their basement walls from the settling of the foundation and the weight of the house. In a stable home, the small cracks aren’t growing at all – they’re safe. If they’re growing, however, you’ll save a ton of money by getting the problem addressed now rather than later.
How do you tell if they’re growing? Take some masking tape and cover up the end of any cracks you notice inside or outside, and write today’s date on the tape. Then, in a few months, check the tape – if you see a crack growing out of the end of the tape, you might have a problem and should call a specialist before the problem gets out of hand.
10. Hang a clothes rack in your laundry room (or better yet, an outdoor clothesline).
Even an efficient clothes dryer can really eat up your energy costs, but it’s convenient for many people. If you’re willing to battle that convenience, you can save money by hanging a clothes rack from the wall in the laundry room and using it for some items; t-shirts, underwear, towels, and pillowcases dry great on clothes racks. If you can hang up 20% of the clothes in a load on a rack, you can get away with running the dryer 20% less than before, saving you cash.
Even better: If you can, install a clothesline in your backyard and hang most of your clothes to dry outside, where a good breeze can do the work of a dryer in no time — and at no cost.
11. Check all toilets and under-sink plumbing for leaks or constant running – and check faucets, too.
Do a survey of the plumbing in your home before you settle in. If you find a toilet is running constantly, it’s going to cost you money – here’s how to easily fix that constantly-running toilet.
You should also peek under the basin of all the sinks in your home, just to make sure there aren’t any leaks. Got a leaky faucet? You should repair or replace any of those because the drip-drip-drip of water is also a drip-drip-drip of money; not to mention the terrible interplay between mold and home insurance.
12. Install LED or CFL light bulbs.
LED and CFL bulbs can save you a lot of money on energy use over the long haul, plus they have much longer lives than normal incandescent bulbs, making them well worth the upfront investment. Consider installing some in various places — especially in areas where the lights may be in use for long periods, like the living room or kitchen, or left on accidentally, like a back hallway or basement. CFL bulbs tend to be cheaper, but LED bulbs are usually preferable in terms of performance and have come down in cost quite a bit over the past few years.
13. Choose energy efficient appliances, even if you have to pay more up front.
Unless you were lucky enough to buy a fully-furnished home, you’ll likely have to do some appliance shopping. Focus on reliability and energy efficiency above all, even if that seriously increases the cost you have to pay up front. A refrigerator that uses little energy and lasts 20 years is far, far cheaper over the long run than a fridge that runs for seven years and guzzles electricity. If you plan ahead, you can buy it with a credit card that offers a big sign-up bonus. You’ll pay the balance off immediately and walk away with hundreds in cash or travel rewards.
14. Set up your home electronics with a SmartStrip or two.
Looking forward to getting your television, cable box, DVD player, sound system, and video game console set up? When you do it, set things up with proper surge protection (to shield your equipment from electric surges). You might also want to consider a SmartStrip, which makes it easy to “unplug” devices that aren’t in use.
A SmartStrip allows the on-off status of one device — say, the television — to control whether or not there’s power flowing to other devices (say, the DVD player or the video game console). Having the power cut automatically from such auxiliary devices can save a lot of money over time, especially since many such devices eat quite a bit of power as they sit there in standby mode, constantly draining your money.
15. Plant shade trees near your house.
Mother nature can help you save significantly on your summer cooling costs — and heating costs in winter, too.
Plant deciduous trees — the kind that lose their leaves in the fall — on the western and eastern sides of your house. The leafy shade trees will naturally cool your home during the hot summer months by reducing the amount of direct sunlight that hits your house.
In the winter, they’ll lose their leaves, allowing that same sunlight to stream through your windows and heat up the home a bit more. And if you plant evergreens on the north and northwest sides of your home, they won’t affect the sunlight, but will shield your home from cold winter winds.
As an added benefit, mature trees can increase your property value. Just make sure to plant them a safe distance from power lines and your home itself (no one wants a downed limb poking through their roof). Plant them now, and they’ll grow and shade your house sooner.
16. Change the locks and make spare keys.
One of the first things many homeowners do is change the locks on their new home. You don’t need to be particularly handy to install new door hardware, and a set of basic doorknobs and locks for your front and back door will only set you back $20-$80 or so. It may seem unnecessary, but there’s no way to know whether there are copies of your old key floating around, and who might have them if so. Investing a bit of money and time today can protect you from burglary down the road.
While you’re at it, get an extra copy of your key made and leave it with someone you trust, so you don’t have to shell out $100 to a locksmith when you inevitably lock yourself out.
17. Air-seal your home.
This isn’t such a problem in new homes, some of which are built tight as drums, but in older homes, it’s important to look for any places where air may be leaking directly into or out of your home. Common trouble spots are around doorways, windows, and even electric outlets.
These aren’t just air leaks – they’re money leaks. Thankfully, fixing small air leaks is pretty easy – here’s a great Department of Energy guide to caulking and weatherstripping, which will keep such air leaks from sucking the heat – and money – out of your home.
18. Take advantage of tax benefits and other incentives.
The energy tax credit, which was set to expire in 2014, was renewed at the last minute in December. That means homeowners who made energy-based improvements to their homes last year were eligible to receive a tax credit for 10% of the cost, up to $500 lifetime. Whether this popular credit is renewed for another year, however, is anyone’s guess. A whopping 30% tax credit toward the cost of solar energy systems, residential wind turbines, and geothermal heat pumps is in effect through 2016.
Your state or city may offer even more benefits, from no-interest loans to rebates, so do some research when you invest money improving the efficiency of your home — you may save even more money than you expected.
Many states and local utility companies also provide home energy audits for free or at a discount. Someone will thoroughly inspect your home to find where you’re wasting energy. They’ll look for air leaks and uninsulated pipes, test the efficiency of your heating and cooling equipment, and even replace any older incandescent light bulbs for free.
19. Develop a home maintenance checklist, and run through it for the first time.
One final tip: Create a home maintenance checklist. This list should include regular home maintenance tasks that you’d want to do on a monthly, quarterly, or annual basis. Then, make it a habit to run through the items on this list every so often. Doing so will extend the life of almost everything in your home, saving you buckets of money over time.
Easter Dirt Cake
Everyone loves dirt cake so why not put an Easter spin on this delicious treat! With no baking involved it’s a great recipe to whip up with your little ones! You can’t go wrong with Oreo cookies, pudding, and cool whip. You can add whatever you want to the top, Peeps, jelly beans, edible grass, etc.
For the carrots, you can whip up some vanilla frosting, then add food coloring to get the orange. Next, put it in a plastic bag and clip the corner off. Squeeze little orange blobs on some wax paper and put them in the freezer for 10 min. until they are set. Use a tooth pick to poke a hole in the top so you can add a few pieces of edible grass. (You should be able to find edible grass in the Easter candy aisle at places like Target & Walmart.)
Easter Dirt Cake
- 1 pack of Oreo cookies
- 1 package 8oz of cream cheese, softened
- ½ cup soft butter
- 1 cup powdered sugar
- 1 teaspoon vanilla
- 3 cups milk

This year instead of store bought St. Patrick’s day treats, save some green with these super cheap and easy recipes!
Shamrock Pretzel Pops
• Bag of Mini Pretzels
• Wilton Green Candy Melts
• Confetti Sprinkles
• Lollipop Sticks
• Wax Paper
STEP 1. After you gather all the ingredients, take the candy melts and place them in a microwave-safe dish. Melt according to package guidelines. I added about 1/4 a teaspoon of shortening (just a tad!) to help the candy soften. I melted about half the bag for about 1 minute and 30 seconds, checking on it every 30 seconds to mix.
STEP 2. Dip each pretzel into the green chocolate with small tongs or fork. You can cover the pretzels completely or let the access chocolate drip off. My pretzels were getting a bit drenched, but they made for even tastier treats!
STEP 3. Arrange the pretzels into the shape of a shamrock on wax paper. You’ll need three pretzels for each shamrock, making sure all the pretzels touch — this will help them adhere as the chocolate dries. Place your stick on top of the pretzels and drizzle with more chocolate to seal. Let set for several minutes and decorate with colorful sprinkles.
Shamrock Punch Recipe
This is the perfect addition to your St. Patrick’s Day theme party! Plus, this would also be fun to serve to your kids on St. Patrick’s Day! This recipe only calls for 2 ingredients which makes it super simple to prepare (and also really cheap)!
1 Carton of Lime Sherbet
1 2 Liter of Ginger ale
Place lime sherbet either in a punch bowl or glass, top with Ginger ale and then allow it to melt slightly before serving!
We hope your family enjoys making sweet memories this St. Patty’s Day! As always, if you have any questions about purchasing or refinancing a home, contact us today! 662.890.3000 • http://www.desotohome.com | mechanical_engineering |

Does not overcharge. I went through 5 HVAC services and he was the only honest one. Just an honest person which is like unicorns these days. Antonio is a retired Marine who owns his own company. Would recommend him. Wish he would do automobile work.
- Chris Matthews. 5/1/2020
We were impressed with Antonio Webb's service. He was professional, thorough, and honest. He checked our AC systems top to bottom. It was the most comprehensive service we have ever received from an HVAC company. Provided great value. We highly recommend Mr. Webb and will continue to seek his service in the future.
- suzanne mcmichael. 4/27/2020
Antonio Webb is responsive, friendly, and a professional. He takes pride in his work and enjoys helping people.
He returned my call quickly and scheduled an appointment for the next day. He updated me of his arrival time and arrived as scheduled.
Antonio quickly resolved the problem with our AC unit.
His pricing is more than than fair. He did not try to up sell me on two new AC units (even with them being 25 plus years old). He simply repaired the AC unit. His entire service call was less expensive than the price charged a few years ago by a "caring" AC company for a small part.
- bluewaterskiing . 4/1/2020
Antonio Webb is an absolute professional. He is easy to contact and works with you to schedule a convenient appointment time. He keeps you appraised of his arrival time and works hard to assess the problem with your heating/cooling system. He got our AC up and running in a short amount of time. I found him to be honest and his charges to be very reasonable (much less than the folks who advertise on TV). He takes pride in his work and is happy to show you just what the problem is and what his recommendation will be. When our system was outdated and could no longer be repaired, I trusted Antonio to install a new one. He gave us a written quote and stayed to his estimate, even when he encountered some issues with removing the old system. I wholeheartedly recommend Antonio Webb from Interior Professional Heating and Air for any installation and service needs.
- Susan Inumerable. 11/28/2019
Anthony is very helpful and experienced in his craft, he knows what to do and so affordable price he quote with extra job for free. He is awesome person i will definitely 100%% will recommend him.
- Marilou Mader. 11/26/2019
Antonio was personable yet very professional! He replaced my thermostat and filters. Had good suggestions and really helped us out. We also appreciate and support his business because he is a veteran!
- Jill McCook. 11/16/2019
Antonio really knows his stuff. I had quotes for twice as much to do the same thing, cool my upstairs area properly. Others told me I had to redo the duct work, etc. Antonio came out, diagnosed the problem, and installed a new 5 ton unit with new vents to properly cool the upstairs. Cannot say enough good things about him. Check him out the real deal. Honest, professional and true to his word.
- Steven Romanoff. 7/28/2019
Excellent and professional service.
- Darleana McHenry. 7/28/2019
Antonio is AWESOME!! The best HVAC service professional that I have met in 30+ years of owning a home.
I wanted both my air-conditioning units & heating systems serviced, and explained a couple of issues we were having with the cooling unit for the upstairs system and the downstairs heating system being slow warming up. He provided a very reasonable quote upfront explaining what is involved. He then did a very thorough inspection of each units of the heating and cooling systems and explained everything each step of the way.
He does not try to up sell any additional service or product but will recommend things if needed and a time line for future repairs. He tuned up my HVAC system to its optimal performance & identified the root cause of my system issues and fixed them, all at no additional cost to the original quote.
He respects your house, and cleans up after the job. I will highly recommend him to anyone needing HVAC service or repair.
- SC Lim. 5/22/2019
We were having an issue with our HVAC system not pushing out any cool air in our upstairs area. I came across a review on Mr. Webb and the HVAC service he provides, so we gave him a call to find out if he could fit us in his schedule for later in the week. I gave him a quick description of what we were dealing with and he offered to swing by that same day. He arrived promptly at the time that was arranged and went right to work at assessing our problem. Mr. Webb gave our AC system a careful, thorough look-through and determined that we had very low coolant levels in our system. Before we knew it, we had cool air pushing out of our vents.
Overall, extremely professional and courteous. Throughout his whole visit he made it a point to explain everything he was doing and why. Where ever he was working throughout the house, he made sure he kept it nice and orderly (putting on shoe booties while walking in and out of the house, laying out blankets on the carpet where ever he placed his tools/ladder). Without a doubt, I will be using him in the future for any additional maintenance work. As a matter of fact, I requested that he put me in his calendar for seasonal check-ups. Unfortunately, they only allow us to give five stars - if I could, I would put more. If your family was in need any type of HVAC service give him a call first - you will NOT be disappointed!!!
- Kimberly Santos. 5/13/2019
Anthony Webb was very professional, knowledgeable and personable as a heating and air technician. He was also extremely patient in helping me understand what the problems were and how to use the thermostat for best results! He was very careful to wear shoe protectors and leave everything as he found it. Anthony was highly recommended to me by people who he had serviced for years!! I will also recommend him with confidence to others for his outstanding work!!!
- Jean Smith. 2/30/2019
Tony came and took care of my heating needs next day. A week earlier than anyone else I called in town. Found errors in the job done before and got er fixed up. Thanks!
- Andrew McConnell. 11/27/2018
Tony did a great job, and his price was affordable. He is a very respectful person and cares about the work he does, checking back to make sure everything is working good. I would recommend him to anyone.

I have done business with Tony for over 20 Years. I have never seen a more honest, caring & professional person in my life. Tony takes prides in his work and assures his customers they will be 100%% satisfied. The fact that Tony is a Veteran explains his meticulous work habit. I have referred Tony to several friends and relatives and they had nothing but praise for Tony and his quality of work.
- Calmom5 . 4/2/2018
We have used Interior Professional Heating and Air (Antonio) on many occasions and have referred him to several friends who have been just as happy with his professionalism, honesty and quality of work. He replaced the heater and air conditioner in our current house and he has serviced and repaired it whenever necessary. He also replaced the heater and air conditioner on our rental property. In addition to getting the job completed in a just a short time at a very reasonable cost, he treated our tenant with the same respect and courtesy he always does us and they were very happy. This is why we continue to refer him to our friends. You wont find a company with more integrity and professionalism. A co-worker was very impressed that he didn't try to just sell them a whole new unit during a service call. He told they still had life left in their HVAC system and advised a different option. Eventually he was the first company they called when they were ready for a new unit in another house. His prices are competitive, his work excellent, but his honesty and professionalism are second to none. | mechanical_engineering |

by Wenjie Mai
What is AFM?
The atomic force microscope (AFM) is one kind of scanning probe microscopes (SPM). SPMs are designed to measure local properties, such as height, friction, magnetism, with a probe. To acquire an image, the SPM raster-scans the probe over a small area of the sample, measuring the local property simultaneously.
How does AFM work?
AFMs operate by measuring force between a probe and the sample. Normally, the probe is a sharp tip, which is a 3-6 um tall pyramid with 15-40nm end radius (Figure 1). Though the lateral resolution of AFM is low (~30nm) due to the convolution, the vertical resolution can be up to 0.1nm.
Figure 1. (a) A new AFM tip; inset: The end of the new tip. (b) A used AFM tip.
To acquire the image resolution, AFMs can generally measure the vertical and lateral deflections of the cantilever by using the optical lever. The optical lever operates by reflecting a laser beam off the cantilever. The reflected laser beam strikes a position-sensitive photo-detector consisting of four-segment photo-detector. The differences between the segments of photo-detector of signals indicate the position of the laser spot on the detector and thus the angular deflections of the cantilever (Figure 2).
Figure 2. AFM is working with an optical lever.
Piezo-ceramics position the tip with high resolution. Piezoelectric ceramics are a class of materials that expand or contract when in the presence of a voltage gradient. Piezo-ceramics make it possible to create three-dimensional positioning devices of arbitrarily high precision.
In contact mode, AFMs use feedback to regulate the force on the sample. The AFM not only measures the force on the sample but also regulates it, allowing acquisition of images at very low forces. The feedback loop consists of the tube scanner that controls the height of the tip; the cantilever and optical lever, which measures the local height of the sample; and a feedback circuit that attempts to keep the cantilever deflection constant by adjusting the voltage applied to the scanner. A well-constructed feedback loop is essential to microscope performance (Figure 3).

There are a lot of things that must work together for a rifle to shoot straight. Basically, in order to get a bullet to fly straight we must first get it out of the barrel straight. That is what this section deals with. For all examples we will assume we are talking about a bolt action rifle. Specifically, a Remington, Model 700, bolt gun.
The rifle has 5 basic parts. They are:
The bullet must come out of the barrel straight. An important concept is the "centerline" of the barrel. This is an imaginary line running right down the center of the barrel bore. We want the centerline of our bullet to match the centerline of the bore. The chamber is reamed into the breech of the barrel. The chamber also has a centerline and it must be the same as the centerline of the bore. Stock rifle barrels are usually pretty good. But for our purposes lets assume price is no object. We want to start with a high quality barrel. Schneider, Krieger, Douglas and others all make match quality barrels.
When a bullet passes down a barrel the barrel goes through a whipping action. The longer and/or thinner the barrel the more it will whip. Benchrest shooters have long held for a shorter and very thick barrel. Lately the trend is toward a little longer barrel with fluting. I can't pretend to be an expert on all aspects of barrel making. Call the people who make accurate rifles (list enclosed) and see what they think. Let's assume though that we want a very thick barrel in the 20 -22 inch range. Fluting a barrel means cutting grooves in the outside of the barrel. They must be equidistant around the barrel and must be cut very precisely. Fluting a barrel changes the internal dimension and can put stress in the metal. If I were to buy a fluted barrel it would be one made by an expert who will take the time to do it right, and stress relieve the barrel properly. Fluting does three things, increases stiffness, reduces weight, and improves cooling (because there is more surface area exposed to the air). Zareh Ohanian - two time winner of the Canadian Sniper Competition, taught me a pretty slick trick that would be a lot cheaper than fluting. Most of you are should be familiar with a process called "bead blasting". It is used extensively in repair shops to clean metal parts. It is not as destructive as sand blasting. Bead blasting is usually done in an enclosed cabinet. The cabinet's hopper is filled with glass beads and high-pressure air and beads are forced through a nozzle -- just like sand blasting. Zareh reports that initial testing showed that a bead blasted barrel cooled faster than a fluted barrel.
I do have some experience with bead blasting, though not on rifle barrels. Glass beads actually remove very little metal. To verify this, bead blast a piece of stainless steel. Before you do it, measure the surface profile of the metal using a profilometer. Imagine dragging a needle across the surface of a record. The record is rough enough that you can feel the needle's vibration as it runs across the grooves. Profilometers measure the roughness in a similar manner, and record the surface finish on a chart. An old measure of roughness, "rms", is an average of the recorded difference between high spots and low spots. (A scratch is a "ditch" in the metal, with high edges and a low bottom.)
Bead blasting knocks tiny dings and scratches in the metal. Just as big grooves (flutes) on a barrel increase surface are, 10 billion tiny microscopic grooves do the same thing. I believe that the roughness increases the surface area of the barrel slightly more than the big grooves!
WARNING: Knowledgeable engine builders never bead blast internal engine components. This is why: those beads are so small that you will never get all of them out. Many are actually embedded in the micro scratches of the metal's surface. They will work loose, get into the engine, score cylinder walls and worse, bearing surfaces. This can cause early engine wear, or at high rpms (like a racing engine), catastrophic engine failure. What do you think will happen to the inside of your barrel when beads are trapped between a bullet and the bore? If you choose to do this to your stainless rifle barrel, do a VERY good job of sealing the barrel at both ends before you do it. After blasting, carefully scrub clean the barrel before you remove the seals. Keep your rifles stored in a different building than the cabinet.
Now while we are on the subject of slick tricks, I'll tell you one I have been thinking of but have never tried. You will need to locate a shop that does "electropolishing". Electropolishing does the opposite of bead blasting, it removes high spots. The metal is submerged in a weak acid mixture. An anode is placed next to the surface of the area to be polished. The ground is attached to the metal itself, and the positive is attached to the anode. Electrolysis causes the tiny ridges to dissolve into the solution. Now here is the idea, for an anode could you not use a tightly strung thick wire/rod running down the centerline of the bore? It would be shielded from the barrel using plugs similar to the buttons used to align cleaning rods. They already make electric bore cleaning systems, could not one of these be adapted to perform electropolishing? This process should make the bore EXTREMELY slick if done properly. Electropolishing removes only traces of metal, and would not change the bore diameter any at all.
The transition area between the chamber and the rifling is called the throat. The bullet will move out of the case neck and move down the throat until it hits the rifling. We will want to make this dimension long enough for our bullet to fit without touching the rifling. If we jam the bullet into the rifling it may stay there if the round is ejected. Also, there is a potential for dangerously high pressures if the bullet is in contact with the lands. The lands are the raised surface of the rifling. If our throat is too long, our bullet will have to float farther before it comes back under control by the lands. Keep in mind that if the bullet floats it will probably start down the barrel a little off-center. We want our bullets to be as close to the lands as is safe. This is usually .003 - .005 of an inch. You may have heard someone say they can't make their rounds long enough to get close to the lands and still fit in the magazine. In that situation, the throat is too long. I have heard many say that the cartridges like the .220 Swift and 7mm Remington Magnum are hard on the throats. This is because there is a large amount of powder burning (heat) at the throat area. In the 7mm RM the problem is more often found in Auto-Loaders (like the BAR) where the owners have engaged in rapid-fire practice. The 220 Swift is just a bad ass cartridge! I think the heat and velocities are enough to burn out the barrel and throat even if the owner is careful and cleans the barrel properly. Beware used .220 Swifts! I have never owned one and I'm only repeating the advice I've heard often from others. They are rumored to have a very short barrel life. (If there are any experienced Swift -O-Philes out there who would care to elaborate on or contradict this assertion I'd love to hear from you.) But I digress.
Zareh also adds that new barrel steels have largely solved the .220 Swift problems, letting the barrel cool between shots, and proper cleaning. Now before we go on lets consider something else. The barrel is threaded into the action. In the factory the machines that thread barrels and cut the threads in actions are different. Each machine cuts the same size threads a little different. Each barrel threaded on the same machine will be a little different because the tooling is being dulled. If we want our action and barrel to fit perfectly we need to have the threads on the barrel cut to match the threads on the action. Machinists call this "chasing" the threads. If I were to spend $1,000 dollars or so on a barrel, I'm not sure I would want someone else cutting threads on it! The preferred method would be to have the barrel guy do the entire fitting. This is not something most people can do in their garage. Good barrels can be had already chambered for $250 - $500 dollars. Add to this the cost of fluting, bead blasting, cryogenic treatment and fitting, and you are getting close to $1000 worth of barrel.
A good action has a number of important qualities. The action must be rigid. Because, its face fits against the barrel, the face of the action needs to be perfectly square, if the barrel is to fit perfectly against it. The spacer between the barrel and action needs to be milled perfectly flat also. On the 700, this is the only change I know of that really needs to be made. Be careful when using actions other than the Remington. The Savage is pretty good, but the Winchester is rumored to be overly flexible.
Now that we have a perfect barrel fitted perfectly to a square action we need a square bolt. On the 700 the bolt has two locking lugs. These lugs lock-up at the 12:00 and 6:00 positions. If the locking lugs do not contact the grooves evenly, when a round is fired the case will move up or down in the back. This of course is a very slight movement, but it is enough to start our bullet out on a crooked path. "Lapping" the lugs, means polishing the one or both lugs so that each will lock up with the same "0" clearance in their grooves. The base of our cartridge rests against the face of the bolt. If the face of the bolt is not perpendicular to the centerline of the chamber, the case can move in whatever direction the face is canted. We must then have the face of our bolt ground perfectly square. The tolerances we are dealing with are on the order .001 - .005 of an inch. This is best left up to people who have the precision equipment to cut and measure things this close.
When the gun fires we do not want it moving around in the stock. If the barrel touches the stock anywhere past the first 1 -1/2" from the action we will have a problem. The stock must be relieved until the barrel floats freely over it. Bedding is the term used to describe filling all voids in the stock next to the action. This provides a strong smooth surface for the action to bind tightly to. Accuracy International has designed a sniper rifle for the British Army that needs no bedding. The action is attached to a steel skeleton that the stock clamps to with bolts. This rifle is also being built under license at the Gunsite Training Center in Arizona. Word has it that all of the current production run is already spoken for.
Bedding an action using Acra-Glass and aluminum powder is pretty easy to do yourself. You may want to try it first on an older/extra stock first. This is how I do it. Take some fine powder like carpenter's chalk and very lightly oil the all of the outside of the action -- anywhere contact with the stock is likely. Now dust the action with the chalk. You want a very light coat of dust all over the parts that may come in contact with the stock. Now fit the stock carefully and tighten down. Carefully remove and observe where the action touched. Anywhere the chalk is light or non-existent is a void that needs to be filled. Now instead of just smearing in the acra-glass as is, it is a good idea to hog out the stock everywhere you have enough material to work with so you can put a lot of filler in. You will not have to worry about the filler being so thin that it doesn't stay put. A Dremel tool is good for this job. You need to pencil the outline of the action on the stock so you know where to cut. I have always bedded out to the first 1-1/2 " of barrel.
Follow the instructions on mixing the glass and aluminum powder. Don't get cheap and do it without the aluminum. Acra-Glass comes in a kit that includes this blue stuff that you apply to the action to keep it from sticking to the glass. Do a very good job on this part! After you lay in the filler press the rifle back together and tighten. Be careful not to get filler where it can get into the trigger group! Let the stuff set and after it's almost hard, remove the action. Trim off the excess and let it dry completely. Now you clean the action and you have a bedded rifle. Follow all kit instructions completely and you should not have any problems.
McMillan Fiberglass Stocks, Inc. is the world's premier synthetic stock manufacturer. Consider that McMillan has supplied over 1,000 stocks to the military and federal agencies for use in sniper systems. All spec-ops unit's use the McMillan stock, as does the USMC.I had the pleasure of meeting the McMillan family at the SHOT Show '96 and was most impressed by the quality and variety of their product line. If you have ever wondered what the difference is between a McMillan and "all the rest", you really need to take a look at both. The difference is obvious, even to a novice.
I don't think I'm going to go to deeply into this for a couple of reason. First of all I have always had someone else do my trigger work. There is a reason that most sane people recommend pulls of AT LEAST 3 pounds. Any less and the chance of an accidental discharge becomes a very likely possibility. "Set" trigger systems are triggers that require two stages to pull. The first stage sets the trigger. Then the trigger can be set to a very low pull. Target shooters have been known to set theirs in ounces, not pounds. Of course, you would not set the trigger until you are certain that you are ready to fire. Many factory rifles now come with pulls set around 7 pounds. It is almost impossible to shoot accurately with the pull set that high. The pressure you must exert on the trigger to fire the rifle is so great that it moves the muzzle too much. (See section on basic marksmanship). I do recommend that you have your trigger set by an expert. I do not mean the guy down the street whose main work includes recoil pads, cold bluing, and cleaning. Find someone who does a lot of this so your trigger and safety will be safe for you to handle. | mechanical_engineering |

Hand tools have been revolutionizing the way we live for 2.6 million years.
Tools make us human, but we are not the only ones who use tools. Some birds drop rocks to crack shells open, and certain apes use sticks to get food or groom themselves. What makes us different is the thought we put into toolmaking, says Ian Tattersall, PhD, curator emeritus at the American Museum of Natural History in New York. Around 2.6 million years ago, our ancestors realized there was a superior type of rock for sharp-cutting edges (likely used to butcher animals). They chose these rocks, shaped them, and carried them for later use.
“If our predecessors had never started making stone tools, we would not be the reasoning creatures that we are today. The invention of the cutting tool opened a whole world of possibilities,” says Tattersall. The lever, however, might be the most important tool to advance civilization beyond meeting our basic needs of clothing and food, says Voula Saridakis, PhD, curator for the collections and archives at the Museum of Science and Industry in Chicago. “So many tools depend on the principals of the lever.” Wrenches, pliers, hammers, shovels, and jacks all helped build our world by harnessing the mechanical advantage of leverage.
Those descendants of the first levers are among our list of greatest tools, and they’re not the only ones with a mechanical lineage that dates back millennia. But all the tools here, new and old, and in no particular order, celebrate humankind’s capacity to shape the world.
Carpenters have this amazing ability to see the unrealized potential in a tool, a piece of scrap wood, even a drywall screw. And if there’s any construction-site artifact that seems to have inspired their imagination, it’s the humble carpenter’s pencil. Really, it’s more than a all-purpose marking instrument that won’t roll away. It’s also a scribing tool, a spacer (the thin side is ¼ inch and the wider face is 9⁄16 inch), and the perfect accompaniment to a tape measure or square.
Typically, carpenters drop these wide, flat pencils—about $3 for a 10-pack, any brand will do—into their nail bag tip first so they can pluck them out and strike a quick line. To do this, put your index finger along the side of the pencil like it’s an extension of your digit, instead of pinching it like you would to write with it. To scribe an uneven shape onto wood, like for lining up a cabinet on a brick wall, lay the pencil on its flat side to translate the shape of the surface (the wall) you want to match the wood to. For curves with a smaller radius or bumpy surfaces, hold the pencil down on its edge.
Although there are dedicated carpenter-pencil sharpeners, it’s another gadget to own, lose, or break. Most carpenters use a utility knife to sharpen their pencils. This allows you more control over the shape of the tip and how much lead you want exposed.
To sharpen the pencil, start on the broad surface with the knife blade ⅝ inch to ¾ inch away from the end. With the blade square to the body of the pencil, use your thumb to push the blade forward, gradually leaning it back so that by the end of the stroke, the utility knife’s blade is just about parallel with the pencil’s lead. Rotate the pencil 90 degrees, and repeat the process on the adjacent edge. Repeat on the broad edge and the remaining narrow edge.
Of all the tools you use to shape wood, the handplane has come to symbolize craftsmanship of the highest order. It’s a cutting tool that’s designed to create truth: dead straight and flat surfaces ready for finishing and joinery. The Lie-Nielsen Handplane is a longtime PM favorite. Sure, it’s stunning to look at, but the beauty is in its flawless flat surfaces, wickedly sharp (and easy to resharpen) cutting edge, and precise adjustment capable of producing tissue-thin shavings.
The Speed Square is arguably one of the most useful building tools. Its markings help speed up repetitive procedures when framing walls or cutting rafters. The original Swanson Speed Square Pro comes with Swanson’s Blue Book, which contains instructions and explanations of the geometry, calculation, and layout of virtually any rafter configuration. If you’re only framing occasionally, it’s a fantastic resource. Aside from framing, the Speed Square can be used for just about every woodworking project, including sheds, shelves, firewood racks, picnic tables, Adirondack chairs, workbenches, and sawhorses.
In addition to marking angles and parallel lines, and laying out rafter cuts, the tool’s flat base makes it easy to check that studs or joints are square (as shown above). One more use: a saw guide. Hold the lip of the square against the bottom edge of the piece you’re cutting and press down on the top to guide the saw for perfectly straight cuts. You can also flip it around to cut at a 45-degree angle or rotate it on the pivot point to cut at any angle.
With locking pliers, suddenly you’re Superman. Use them to clamp metal for welding, grab onto stripped bolts, pull nails. The original Irwin Vise-Grip 10WR locking plier is simple, well-built, and still great in all respects. The new model has built-in wire cutters and a recess in its adjusting knob to accept a 3/16-inch Allen wrench that lets you more easily and precisely adjust and release the tightening force.
The Skil worm-gear circular saw (Skilsaw) will turn 100 in a couple years. A century is a blip in the timeline of tools, though among powered, handheld implements, it approaches an eternity. The Skilsaw makes use of a spiral steel “worm” on the end of its motor shaft, which spins a worm gear below it. The output from that gear drives the blade, reducing motor speed and increasing torque. Today’s descendant, the 7¼-inch Lightweight Skilsaw, is an impressive refinement of the early models, now about half the weight (a reasonable 11 pounds 8 ounces), faster, and undoubtedly safer. And its revelatory capability—a portable saw ready to frame your next house, and the one after that—remains.
There are few landscaping tools as useful as a round-point shovel. It digs and moves dirt, gravel, sand, snow and ice, debris, asphalt, and concrete. It scrapes, pries, and chisels its way through roots, and is even helpful in fighting brush fires.
A shovel also makes an amazingly effective fulcrum to move the practically immovable from your lawn: Lay an open-back shovel facedown on the ground, place the tip of the digging bar under what you want to lift (such as a fence), and place the length of the digging bar into the blade crevice. You can use your foot on the digging bar to provide force. The round nose gives you the ability to rock the shovel slightly left or right as needed to aid in the lift.
A quick note: Square-nose shovels are quite agile in demolition work, where they can pry off drywall, scoop out insulation, and lift appliances for removal. But for its versatility, our desert-island shovel is this Bully Tools 14-Gauge Round Point.
The tools that literally built civilization predate records. But we can place the first level, the plumb bob, in Egypt as far back as 2700 B.C., Saridakis says. There, it guided the builders of the pyramids and other perfectly squared structures that still survive.
The Egyptians’ tool looked and functioned almost exactly as it does today: a pointed weight, hanging from a string. When you suspend it, for example, from the top of a doorway, you can compare the distance from the side of the doorway at the top of the string to the distance from the side to the bottom of the weight to determine whether it is square. It can also be suspended from an A-frame to act as a horizontal level.
Its name comes from the Latin word for lead (plumbum), and it was a vital tool in the construction of the Roman Empire, says Saridakis. The tool even earned itself a Biblical metaphor in Isaiah 28:16–17, which reads that God “will make justice the line, and righteousness the plummet” in Zion.
A modern laser level from Bosch or Milwaukee is a fine addition to any tool kit today, but we still carry a plumb, like the Empire 8 oz. Steel Plumb Bob, as well. It’s indestructible and immune to ambient light, and the battery never dies.
The screwdriver is so fundamental today that it’s tough to think of any professional trade job or DIY project that doesn’t require at least one. More likely, you’ll need two or three, maybe more, which is why, since its introduction in 1988, we’ve been huge fans of the Picquic multi-bit screwdriver. The Canadian toolmaker now offers 10 versions, with the Picquic Sixpac Plus as its flagship. In its body, the screwdriver stores six ¼-inch bits—tough enough to use with an impact driver—while the aluminum shank with a magnetic base holds the working bit (a seventh one) firmly in place.
If there’s anything a Leatherman tool is, it’s an achievement of engineering. The Leatherman Wave+ is typical in that respect. It would be one thing if the tool packed in knife blades, pliers, and screwdrivers, and only some of them functioned. But everything works on a Leatherman. Tetris 18 tools into an 8.5-oz. package that is 4 inches long and about ¾ inch thick; if that isn’t a marvel, we’d like to know what is.
When a generation of new American families wanted to settle down after WWII, the early Paslode pneumatic nailer ensured they got roofs over their heads. From the 1940s to 1950s, new-home construction doubled. This feat was pulled off with new time-saving technology like the nailer and circular saw. Instead of taking seconds to pound in a single nail, multiple nails could be fired in a second. Builders and framers gained a new level of mastery over the worksite.
Today’s favored pneumatic nailer from Paslode, the 3½-inch 30-Degree PowerMaster, is a heavy-duty nailer that doesn’t sacrifice convenience. It features manual or sequential firing trigger options and is capable of sinking up to 12 nails per second. It’s also designed for simple depth adjustment, so you can easily calibrate the depth of your nails. This model is also perfect for toe-nailing, thanks to a spiked nosepiece that allows you to securely bite into wood as you fire.
Every trade has its hammers. Metalworking has the ball peen, masonry has stone and brick hammers, carpentry has framing hammers. Each hammer is optimized to its tasks, perfect in its own way. But there is one universal hammer everyone old enough to carry a toolbox should own: the trim hammer. Our shop has had this simple, all-steel 16 oz. Estwing Rip trim hammer for about a decade. The thing is indispensable and unbreakable, and will handle everything but framing—and frankly, it will handle even that for small DIY projects.
It can cut up a box, but don’t call it a box cutter. On a jobsite, it cuts shingles, roofing paper, drywall, and building paper. It can trim mason’s string and scribe lines on wood—and if needed, scribe on steel and aluminum. The nearly indestructible Stanley 99 maintains its 1960s industrial look, but now it also has a reinforced nose to better hold the blade in place.
The floor jack opens up a world of possibilities to the home mechanic. Beyond the oil change, it lets you quickly swap out wheels, repair brakes, or install a catalytic converter cage. It can also lift or lower components such as the suspension, exhaust, and even a differential or transmission.
The first known use of hydraulic power dates back 8,000 years to irrigation channels in Mesopotamia, though water wasn’t pressurized and used as a tool until the mid-18th century, and the first hydraulic press was patented in 1795. Hydraulic jacks (lifting instead of pressing) appeared in the following decades.
Today’s floor jack is a horizontal hydraulic bottle jack with a short lever on one side to lift and a long lever (handle) on the other to apply pressure. That detachable handle might be the second-most useful tool in a garage; slip it over the end of a breaker bar to dislodge especially stubborn bolts.
A good floor jack is made to be serviced, says Craig Hoffman, spokesman for Harbor Freight Tools, makers of floor jacks like the Daytona 3 Ton Professional used by many of our staff and writers. The chrome ram can be cleaned and relubricated, and the rollers underneath it can be greased for easier movement. And changing the oil every three years maintains the jack’s power.
A reciprocating saw can cut through lumber even if it’s embedded with nails. Heck, it can cut through just about everything short of a rock. It’s the go-to tool for remodeling and demolition. You may also know it as a Sawzall, due to the dominance of that Milwaukee Tool recip saw. And while the category has become crowded, we still recommend, use, and try not to abuse too badly the Milwaukee 15 Amp Super Sawzall. It can cut all common forms of metal: steel, aluminum, copper, and cast iron. Of course, the blade you pick makes all the difference (see below).
For cutting through construction lumber, which typically has nails embedded in it, use a blade like Lenox Gold. You can also use a demolition blade, which is wider and thicker, making it better able to resist bending. If you expect to cut metal and want a single blade to handle everything, choose one with 10 teeth per inch (tpi). Although this blade will cut less aggressively, it will be easier to control. As a rule of thumb for metal cutting, use a relatively coarse blade (fewer teeth, like 18 tpi) for thick metal, such as when cutting bar stock. Use a blade with more teeth (24 tpi) for cutting thin metal and tubing.
Choose a longer blade if you want to cut wood or metal flush to a surface. The extra blade length allows you to flex the blade into a curved shape, letting you saw away the wood or metal as you run the blade against the surface from which you are removing it.
If there is one power tool that can get you out of a tough spot during a home repair or remodel, it’s the oscillating multitool. It saws, grinds, sands, scrapes, and polishes. It does nearly anything you need to do, with the exception of drilling holes, and works in places other power tools can’t reach, such as undercutting wood door trim to clear thin-plank flooring. And it works on a variety of materials: steel, aluminum, carpet, hard tile, soft tile, hardwood, softwood, and various plastics. The Fein Multimaster has gained a following over the last 25 years as tradespeople and accomplished amateurs have recognized its outsize ability and durability. It’s practically our right hand in most home projects.
A digital multimeter is an indispensable tool for testing, diagnosing, and troubleshooting electrical circuits, components, and devices. The first digital multimeter was introduced in the late 1970s, and has proven much more reliable than the old needle-based analog meters. It’s used primarily to measure voltage (volts), current (amps), and resistance (ohms). We regularly turn to the highly accurate Fluke 115 Digital Multimeter, which also measures continuity, frequency, and capacitance, and can display the minimum, maximum, and average readings on its large screen.
If a cordless power tool is dying faster than usual, you can check it by measuring the voltage with a multimeter: First, run the tool until the battery is nearly but not quite drained. Then recharge it and check it with the multimeter set to VDC (voltage direct current). Use the next-highest setting above the battery’s voltage, such as 20 volts for a 12v or 18v battery. Press the test leads against the battery terminals. A low voltage indicates that the battery is ready to be recycled (Lowe’s and Home Depot will take them) and replaced.
The familiar pistol-grip power-drill shape emerged from the labs of S. Duncan Black and Alonzo Decker around 1917. And WWII spurred the creation of lighter drills for the factory women that kept America running. These smaller drills became prized for home repair work and had a tendency to walk out of the factories, says Peter Liebhold, curator emeritus for the Division of Work and Industry at the Smithsonian.
Cordless models emerged in the 1960s, but they were expensive and the batteries were more useful as doorstops. By the 1980s, Makita’s 7.2v cordless drill began to catch on, first with repair technicians for small jobs. By the end of the decade, remodelers, electricians, and plumbers similarly embraced the handy tool.
Today’s lithium-ion-battery drills are a revolution in themselves for their power and reliability. And our favorite drill in the shop today is DeWalt’s DCD999 for the control provided by its three-speed transmission and an 11-position clutch ring.
The 2.6 million years since our first stone chopping tools is an intimidating history to stand up against. It’s unfair to expect that we—as multiple species over this timeline—would create the greatest tool known to any life-form. Instead, we seek a platonic ideal of the axe itself: What is today’s perfect chopping tool? Our best answer is the Council Tool Velvicut 2lb Hudson Bay. Its carbon-steel head is sharpened and honed by hand and sits atop an American hickory handle, all balanced to help you hit your target every time.
The wrench, one of the most obvious descendants of our prehistoric levers, largely operates on the premise that for every fastener there is a matching wrench or wrench socket waiting to rotate its flat, consistent surfaces.
Except that’s not how the world works. Try to remove a stuck hex bolt with a 12-point wrench, and those six sides can become one. When it looks like you’ve got nothing to wrench with, a pipe wrench will save the day. (They’re also unmatched on pipes, of course.)
Developed by inventor Daniel Stillson around 1869, the pipe wrench is set apart by its intentionally loose, adjustable upper jaw with hard serrated teeth. That play allows it to bind and clamp down on a pipe or stripped screw when you push the handle of the wrench down. It also spares you from having to reset the wrench when you pull up on the handle, as pulling up unbinds the jaw from your stripped nut or pipe. Just make sure you’ve left a space between the back of the wrench opening (the side without teeth) and the object being turned to give the jaws space to tighten down.
Since Stillson’s patented design, the greatest advancement has been the aluminum wrench body, which can reduce the tool’s heft by around 40 percent. That’s a crucial weight savings, whether you’ve got the tool in your hand all day or just need to reach a single awkwardly placed pipe. Ridgid’s 12-inch aluminum straight-body pipe wrench clocks in at a reasonable 2.5 pounds despite a heavy-duty build. It’s also made entirely of replaceable—and warranty-covered—parts. It’s a tool you can expect to never replace.
Greek mythology offers this origin for the saw: Talos, nephew of prolific inventor Daedalus, found inspiration in a fish spine and modeled a jagged strip of iron after it to invent the first saw. Historically accurate? Not a chance. The first known metal pull-saws date back almost 7,000 years. And by the end of Talos’s tale, he’d been turned into a partridge as protection from his now-jealous, murderous uncle.
The 19th century’s mass production of steel gave us today’s saws. For most of the last two millennia, saws were made of iron, says Ted Ingraham, director of the Zlotoff Tool Museum in South Hero, Vermont. Iron isn’t a particularly hard metal. And the ensuing kinking, or twisting, of the blade was such a problem it earned the old two-person saw the name “misery whip.”
Around the 1880s, a golden age of saws dawned with the wide availability of more durable and flexible steel. Two-person steel saws drove the booming American timber industry while smaller steel hand saws offered a vast improvement for woodworkers. The saws of this era were built to last—built for someone to make their living using it. Many of these steel saws remain today, but if you don’t have the time and patience to hunt one down, 181-year-old toolmaker Disston is reintroducing its D-8 hand saw.
The earliest tools of measurement were nothing more than notches marked in a length of wood or stone, but evidence of measurement systems shows up in writings on cuneiform tablets from ancient Sumer roughly 6,000 years ago, says Saridakis. Ancient Egypt had the first known standard measure, the royal cubit (about 21 inches), based on the length of an early pharaoh’s arm from elbow to middle fingertip. Inscribed wood rods—the first rulers—used to measure out the royal cubit and its fractions still survive after roughly 3,000 years.
The next great leap in handheld measuring tools didn’t arrive until the 1820s with the spring-back measuring tape, though it still required a large, donut-shaped carrying case. The first truly pocket-size tape measure arrived in 1963 with the Stanley PowerLock. That design is so rugged and reliable that Stanley still uses it—and we’re still using our PowerLocks.
Place the tape’s hook where you’ll be making the cut. Put the tip of the utility knife blade against the hook and pinch the blade there with your thumb. Your other hand goes at the end of the drywall, pinching the appropriate-length measurement on the tape. From there you move both hands at the same time, drawing the knife and tape down the drywall with consistent downward pressure. Crack off the piece of drywall and cut the paper on the other side to release it.
Few tools still used the world over were so perfect at inception that they remain largely unchanged. Yet some of the early needles from around 27,000 years ago could absolutely put a button back on your flannel today. The sewing needle was also a key technology that set humans apart from Neanderthals, who never discovered or adopted the tool. Back then, sewing allowed our ancestors to build weathertight shelters from animal hides and create warmer, less-drafty clothes for our long procession around the globe. A starter pack for this auspicious tool, like the Singer Assorted Hand Needles, may not fit in with the rest of the implements in your toolbox, but it deserves a spot next to it. And about that button you’ve been meaning to reattach…
Starting at the inside of the shirt, poke the needle through the fabric and thread it through the button. Bring the needle downward and thread it through the diagonal opposite hole and the shirt. Repeat three times, then do the same on the other two holes. Once the button is secure, poke the needle up through the fabric at its base. Loop the thread around the stitching underneath the button six times. Then poke the needle through that stem sideways three times and cut to secure it.

They were established by two Quaker families, the Foxes of Falmouth and the Prices, who had worked with James Watt at Falkirk. They brought Cornish technical expertise in casting and engineering to this part of south Wales. As you walk from the abbey to the main road, straight ahead of you is Ty Mawr, the ironmasters’ house, built by Peter Price in 1801. A plaque commemorates Joseph Tregelles Price, founder of the Peace Society.
There is now no entrance to the ironworks from the main road, though you can peer through the gates of the builders’ yard and see the engine manufactory and the great masonry furnaces. Turn right up Longford Road. To your right is the charging platform for one of the iron furnaces. Just after the railway viaduct, a path goes down to your right towards the old tramroad bridge across the Clydach.The parapet of the bridge is made from carved blocks of copper slag which probably came from the works in the abbey. Under the bridge is a weir which would have held water back to power the iron works. You can turn right again before the bridge for a closer look at the iron works.
The most impressive part of the ruins are the late eighteenth-century furnaces, two of the highest masonry blast furnaces ever constructed. The casting houses which would have stood in front of them have gone, but you can still the line of the railway which would have taken materials to the charging houses at the top of the furnaces.
A little further on, the roofless building to the right of the entrance, behind the ironmasters’ house, is the shell of the engine manufactory. A projecting wing of this building extended towards the Clydach river and a water wheel powered by a leat from higher up the stream drove a series of machines. Much of the machinery for the works was made on site. There were two cylinder-boring workshops on the ground floor of this building, a fitting shop and smithy. Upstairs was the pattern-makers’ workshop.
Opposite the furnaces and almost completely overgrown (you can just see them in winter) are the ruins of the forge with its water-wheel housing. Here there was a wrought iron bar and tinplating mill. | mechanical_engineering |

These are cyclone dust collectors and they come in many shapes and sizes. If you are curious how they work or are wondering which one will be the right one for your process, read on.
HOW THEY WORK
Cyclone dust collectors filter dust by utilizing centrifugal, buoyant and drag force. When dust laden air enters the cyclone at a controlled speed, the heaver dust particles are forced to the outside of the cyclone wall. This friction allows the dust particles to drop to the bottom of the cyclone into a collection device. The spinning air creates a secondary vortex in the middle of the cyclone that that exhausts the clean air out the top. Cyclones operate at various efficiencies depending on factors such as height to width ratio, water pressure drop, cfm and inlet type.
Most cyclone collectors never operate at peak efficiency. In order to reach maximum efficiency, all the factors mentioned above need to measured precisely and the cyclone manufactured to the specifications based on those measurements. If designing a new system, these measurements can be estimated closely with a knowledgeable engineer and precise measurements of duct length runs and sizes. However, the expense of manufacturing a custom cyclone collector to match these measurements is cost prohibitive. Instead, purchasers should look for a cyclone that shows efficiency based on CFM to water pressure drop and choose the appropriate cyclone for their application.
Efficient cyclones are capable of filtering 90% of particulate down to 15 microns. Options for collecting more particulate may consist of adding an additional cyclone in a series increasing the efficiency an additional 90%, making the total efficiency 99% down to 15 microns. If smaller particulate size is the issue for additional filtration, a bag house filtration system can added to a single cyclone or after the secondary cyclone.
THE INVOLUTE INLET
The involute inlet is an important part of any cyclone dust collection system. The involute initiates the cyclonic action of the dust laden air when entering the dust collector. This allows the clean air vortex to exhaust without the disruption of particulate entering the cyclone. Without this feature, dust laden air would enter the cyclone directly into the exhaust vortex removing much of the efficiency.
DO YOUR HOMEWORK
If you are in the market for a cyclone dust collector, there are some steps you can take to insure you obtain the efficiency that you require for your application. Know your CFM requirement. This is calculated by knowing how much airflow you require at each pickup point within your system. This can be a single pickup point or several. Know your water pressure drop. This is calculated by understanding how much force it will take to move the air at the CFM you require. If these calculations are beyond your knowledge, make sure to hire an engineer who is knowledgeable in dust collection or a dust collector manufacturer that has the engineering experience and willingness to assist you in making these important calculations.
One of the latest trends in down draft benches is the addition of return air flow, also called air-makup. The idea is that re-directing the exhaust air back toward the bench will force more particulate down toward the filers, thus increasing the amount of dust that can be collected. There are several reasons why this is a bad idea.
Standard filters used in these systems are capable of filtering up to 99% of dust down to 1/2 micron, which is excellent. However, the 1% of dust that makes it through the filter is typically dispersed throughout the ambient environment to expose workers to safe levels of the dust. By redirecting the exhaust air back at the worker, the contaminated air is concentrated around the worker at the table. Additionally, this is air with the most dangerous dust. At 1/2 micron or less, the dust is easily ingested by the worker and is easily absorbed by the body.
The best scenario for airflow at the work deck is to pull ambient air into the system. The less disruption to this airflow the more efficient the equipment will be in capturing dust. The disruption caused by the return air flow blowing can create “eddys” (just like in a river) around the worker and/or the material being processed on the bench. This again can lead to the worker being exposed to higher dust levels.
It turns out that return air flow is an add on expense that just doesn’t make sense. It sounds like a nice option and it allows manufactures to under power the equipment to achieve a higher FPM (feet per minute) at the deck.

High Efficiency Cyclone Dust Collectors
Using a special high-efficiency design, the Tornado TXE is capable of approximately 90% collection efficiency down to 15-20 micron particles.
TXEs arranged in-series on a single platform are capable of approximately 99% collection efficiency down to 15-20 micron particles. Tornado TXE high efficiency cyclones are some of the most maintenance free dust collectors available. With no moving parts other than the motor and no filters to replace, they will provide years of low-maintenance, reliable service.
For applications involving particulate below 15 microns, optional after-filter assemblies are also available. Polyester Felt Bags provide standard efficiencies of 96% down to 5 micron. Alternate filtration media can also be used to further increase particle collection efficiency—including HEPA for 99.97% to .3 micron.
Our Involute Inlet
Centrifugal force causes heavier dust particles to move outward toward the cyclone wall. Friction and gravity then force the dust to fall into a receiver. Cleaned air spirals up the center vortex of the cyclone and exits at the top.
It is extremely important that the vortex that forms in the center of the cyclone and exits the exhaust is not contaminated by particulate entering the cyclone. The ProVent TORNADO TXE prevents this by initiating centrifugal force in the inlet forcing particulate to the outside of the cyclone prior to entering the cyclone. This is known in the industry as an involute inlet and makes ProVent dust collectors the most efficient in the industry.
Tornado TXE and TXEF are the best designed, built and efficient cyclone dust collectors on the market.
Cyclones can be utilized on a number of different applications. Volume (CFM), pressure (wg), and velocity (FPM) all impact performance. ProVent can help you make the proper selection based on your specific application.

Many manufacturing and processing facilities have operations that expose their employees to dangerous levels of airborne contaminants. The installation of proper process ventilation systems can save companies from the hassle of dealing with OSHA citations.
Industrial ventilation is necessary to ensure clean air standards are met for the health and safety of industrial and manufacturing employees. This is of particular importance for industries involving toxic chemicals, flammable vapors and debris, welding fumes, solvent vapors, oil mists, and unwanted affluent of all kinds. Industrial ventilation typically involves installing systems to supply and exhaust ventilation to control emissions, exposure, and chemical dangers in the workplace environment. Installing ventilation systems, such as downdraft benches, oil mist collectors, and dust collection booths are much easier and cost effective for industrial companies than some of the alternatives such as process changes and chemical or material substitutions or eliminations. When employees are exposed to dangerous levels of chemicals, dust, flammable vapors, and other air contaminants, OSHA requires that the employers take steps to reduce exposure to safer levels.
The design and troubleshooting of industrial ventilation systems should be handled by a qualified ventilation engineer or companies specializing in the field through an onsite inspection of a company’s process ventilation needs. An inspection such as this can save a company thousands of dollars by preventing improper equipment selection and system design by staff in a hurry to bring their facility up to OSHA standards.
Some industries require very specialized ventilation systems. Oil mist collectors are required for industries that have airborne process oil and coolant from industrial machining operations such as vehicle and vehicle parts manufacturing. Oil mist collectors are particularly easy to fit into existing operations. Another more specialized type of ventilation system are a down draft bench systems which are self-contained ventilated workstations. These are particularly useful for hand grinding, sanding, and deburring operations. Down draft bench systems are also excellent choices for mixing and weighing operations, as well as, sparking operations or combustible metal processing and fiberglass finishing operations. When the process requires a larger area, dust collection booths are more appropriate. These are also useful for grinding, deburring, sanding, and polishing operations.
Many industrial ventilation manufacturers and installers offer jobsite consultations to determine the best ventilation equipment and systems are best for a particular facility. These engineers can help decide if a company should choose equipment such as oil mist collectors, down draft benches, or dust collection booths are best for their type of facility.
See www.proventilation.com for more information on industrial ventilation systems and oil mist collectors, down draft benches, and dust collection booths.
The Wet-Type dust collection market has been steadily growing over the past ten years for several reasons. Companies’ awareness of NFPA Guidelines has increased over this time period and they now realize that wet-type dust collection is a worthy and often necessary investment for their operation. The risk of a fire and the consequences which include significant production down time, employee injury or even death makes wet-type dust collection necessary in certain applications.
NFPA 484 is the Standard for Combustible Metals. This standard applies to the production, processing, finishing, handling, recycling, storage, and use of all metals and alloys that are in a form that is capable of combustion or explosion, as well as to operations where metal or metal alloys are subjected to processing or finishing operations that produce combustible powder or dust. (www.nfpa.org/484). If your process involves aluminum, titanium, magnesium, zirconium, tantalum, and/or niobium, NFPA 484 pertains to you. In most instances a wet type dust collection system is preferred for rendering these combustible materials inert. There are no expensive filters to replace, no chemical isolation systems to re-charge. While dry filtration systems become less effective as their filters load with dust, orifice impingement wet systems do not.
The cost of outfitting dry filtration systems with appropriate passive and active controls to comply with NFPA requirements has become prohibitively expensive. Passive controls involve special explosion vents and ducting to control pressure and to direct and extinguish flames. Active controls involve pressure/flame detection, and chemical isolation and extinguishing systems. These systems need to be regularly checked and re-charged, adding further to the cost of a dry filtration system. Wet collectors simply do not require these systems because the combustion hazard is removed immediately when the process material enters the water scrub.
There are two main types of wet-type dust collectors. The orifice / impingement design and the internal / venturi design. The O/I design utilizes a large cone-shaped orifice and an impingement plate that resides inside and on top of the cone. This creates an extremely efficient “scrub”. The scrub is where the dust entering the collector is mixed with water and sinks to the bottom of the collector and is the most important part of removing particulate. The process works best when the water surface to air ratio is highest within the scrub, thus making the most water to particulate contact. The O/I design does this most efficiently by removing 95% particulate down to 3 micron with just 3” wg of pressure drop. Additionally, by utilizing a wide opening in the cone, the O/I design will never clog.
A contributing factor increasing demand for wet-type dust collection is the increased use of materials suited for wet-type dust collection in products being manufactured. Aluminum and Titanium are the two most common metals where processes that create dust need to be rendered inert in a wet-type collection system. From aerospace to golf clubs, these metals are turning up in our products more often.
Other emerging markets for wet collection include food processing and pharmaceutical industries. Wet dust collection systems are used very effectively when process dust is water soluble and biodegradable. The wet system effectively captures dust where it is thoroughly scrubbed out of the air, dissolves, then simply drains away. There is no combustion hazard. There no exposure to workers by contaminated filters and little down time wasted by filter changes. Processing this way is less expensive and reduces a company’s environmental impact by avoiding costly trips to the land-fill with dirty filters. We have seen a move in this direction just in the past year. More and more companies are beginning to see that these simple advantages add up to significant savings and public relations advantages over time.
Currently, about half of the wet-type dust collectors we manufacture are stainless steel. Companies in the food processing industry are finding uses for wet-type dust collection and require the sanitary benefits of stainless steel for their applications. Stainless steel also increases the life of the dust collector approximately 70% making it an attractive option for companies willing to spend a little more money now and reap the benefits later.
Looking forward, companies are increasingly utilizing wet-type dust collection for unique applications that, we as a manufacturer, never considered. Recently a company had a process that created dust with a sticky residue. They were constantly replacing cartridge filters in their very large dry collection system. The ductwork required frequent cleaning and production needed to be halted during these maintenance operations. The process dust tested to be soluble and biodegradable and they are in the process of replacing a large dry cartridge dust collection system with a wet-type dust collection system. This solution will save the company hundreds of thousands of dollars in maintenance and production down-time in the coming years.
Wet-type dust collectors have been around since the late 1930’s. However, with today’s highly technical processes and materials, the benefits of wet-type dust collection is just beginning to be realized. Configurations such as piped systems, booth systems and down draft bench systems has allowed wet-type dust collection to be available for a wide range of processes. This, together with the small footprint requirements, elimination of expensive ductwork, and low maintenance requirements will continue to make wet-type dust collection more popular than ever in the coming years.

If there is too much dust in the workplace, it can cause many problems and the most serious is the short and long term health problems. Not only does dust make the place all messy and dusty, but also means you and your employees are breathing in harmful particles. The problems usually start off by allergic reactions and can turn into major respiratory problems. Also, a large amount of dust at work interrupts machinery and causes several malfunctions, which can result in a costly experience for you. However, the solution to your problems are dust collection booths.
What They Are
Dust collection booths are ideal pieces of equipment for workplaces that produce both a small and large amount of dust. They are perfect systems for those who wish to have a healthier and safer work environment. A dust collection booth is directly setup inside the workplace and controls the dust.
What They Offer
Dust collection booths offer a high level of control for dust, pollutants and dangerous particles that can be harmful to both the equipment and employees. With one of these systems in place, all pollutants are removed from the workplace, which results in cleaner air both inside and out.
A dust booth works perfectly well with dangerous materials, especially if a wet filter dust collection system is included. A dust booth is designed to work with dusts that are potentially explosive and provides a safe collection of the materials, as well as clean air that is OSHA and NFPA approved.
There is a huge variety of dust booths and these include the wet-type dust collection model, flood curtain booths, and the environmental work cell. The environmental booth is specifically for projects that involve sanding, finishing operations, chemical mixing, welding, and grinding of tools. A flood curtain booth suits projects like deburring, hand sanding, media blasting, and metal spraying. Lastly, the wet-type booths are designed for dangerous materials.
When selecting the dust booth for your workplace, it is important you consider the materials you work with. Speaking to an expert prior to choosing the final system is recommended, and ensures you make the right choice.
Working with metal and wood results in the release of harmful dust particles into the atmosphere, which is dangerous to the workers’ health. Continuous exposure to these particles means your employees will be breathing in the dust, which can lead to both short and long term health problems. In order to maintain the health and safety of your employees in the workplace, downdraft tables must be in place. They are made to solve the problem and controldust by cleaning the air, and give you a healthier and safer work environment.
What They Do
Downdraft tables give workstations a built-in ventilation system that is intended to catch and filter fumes, smoke, and dust. The air that gets filtered is driven back into the environment, which eliminates energy loss and any need for costly in-house exhaust systems.
Downdraft tables are highly efficient in controlling dust from buffing and sanding, which is caused in woodworking places. Metal workers can also benefit from a downdraft table, as their work can result in the production of large amounts of highly toxic dust. These systems are also a must for workstations dealing with composites, welding and plastics.
A downdraft table is made from high quality materials, which helps it to resist a multitude of tasks. You will find they come in numerous types, which includes portable cartridge, cartridge, wet, stationary tables, and walk-around ventilated. The one you choose highly depends on the materials that you work with.
Because of the huge variety in types and sizes, you will always find the ideal ventilation that is suitable for your workplace. This ventilation system can increase both yours and employees’ health, as it will limit the exposure to the harmful dust particles and offer you cleaner and purer air to breathe in.
A downdraft table is a multipurpose way to protect employees and easily meets the safety standards set forth by industries. You will be provided with a reliable and safe workstation, which you employees can safely work in.
Speaking to someone who specializes in industrial air collection will always help with selecting the setup that will work best for your industry.
Factories that produce heavy dust particles require a dust collector system in place, so employees can breathe in clean and pure air at all times. Also, with one of these systems in place, machinery functions well and lasts longer. Dust collection booths also help limit dust into a closed area and safely trap it inside a closed space for easy removal. When it comes to dust collection booths, there are many available, and the most common ones are listed below.
Flood curtain booth
These are used mainly when working with metal spraying, media blasting and hand sanding. They require the use of water, which is stored in a tank in order to flood a stainless steel vertical wall, where the procedure affluent is absorbed. Flood curtain booths can use roof and wall panels to trap extra dust and they can also contain illumination for the booth.
Environmental Work Cells
These are used in numerous working conditions, which include welding, sanding, chemical mixing, powder coating and grinding. They are made from 12-gauge all linked construction that is high quality. Environmental work cells incorporate pleated cellulose cartridge filters with high efficiency fan assemblages, and feature dust drawers; these are easy to access from inside the booth.
Wet-Type Dust Collection
The last of the dust collection booths is the wet-type dust collection. This requires a formation of blowers to power dust particles and pollutants against a series of water walls. The water walls wet the airborne pollutants and trap them away from workers and machinery. These are mostly used for sanding operations, deburring, and grinding. They are made from solid-fused heavy sheet steel and come in the availability of numerous sizes.
A dust collection booth is used to capture particles and other pollutants that can affect workers’ health in the workplace. Another thing that can be affected by the continuous dust is the machinery in the workplace, as the constant exposure of dust means it eventually builds-up and causes malfunctions in the equipment, which means more repairs. This device saves companies and industries a lot of money, as they don’t have to repair machinery often and because the worker’s health is better, they will also perform efficiently. Save the health of your employees and your expensive equipment with this ventilation system.
Downdraft benches allow a more comfortable practice with collection of dust in your factory or office. They have many other advantages apart from just taking care of all the dust and these are listed below.
Downdraft benches feature special filters that let you clean up dust from almost any type of work setting. They are well-known for this feature and the whole process is a breeze, one you know how.
How It Works
A downdraft bench system filters out the air within your work or office space and returns the cleaned air into the floor. This means you will always be free from hazardous particles and dust, which are both dangerous for health. Downdraft benches also save a lot of power, which is a brilliant factor to help you cut down on energy costs.
How Downdraft Systems Benefit Employees
Once this system enters an office, it increases employees’ work performance, which is due to the much healthier environment they will be working in. Employees become more efficient workers, as they can breathe in air that is both pure and clean, which has a healthy effect and lessens absent rates.
However, there’s more! As well as benefiting employees, this system also benefits machinery as it is less likely to rust, dust and stop functioning. Machinery also needs taking care of and if you have well-functioning machinery, this results in little wear and tear and fewer repair costs.
Overall, a downdraft bench system decreases working costs and increases profit by helping your workers perform better. You are also saved on power costs and the whole procedure is hands free. This means it requires less manual effort.
The durable system is made of stainless steel, which is the kind that doesn’t rust. Before creating these tools, the material used was both tried and tested. With the help of this system, you can easily clean fumes and dust from your work setting and reduce the risk these particles can have on the health. These systems are a must for all industries and are really helpful tools, which should not be overlooked.
Pollution is a common factor in today’s environment and it is vital to find a system that will help to maintain cleanliness and hygiene. Not only will a system like this help us in personal activities, but will also do the society a huge favor. The only way to achieve this goal of maintaining a pollution-free and environmentally friendly environment is with downdraft benches.
Downdraft benches are specifically designed workstations or tables with ventilation that enables them to filter out the contaminants and return clean air to the environment, including your workspace. Downdraft benches come in various sizes, which allows you to browse through a variety of options and choices before you select the final one. These systems can be used on various applications, and can even clean up building or fused materials that have been wasted or used.
One of the first things that will change is the quality of air that is breathed in by you and your employees. This workstation also increases efficiency of both your industry employees and machinery. If the air is cleaner, your employees will be breathing in pure air, which results in better performance, less illnesses; therefore, less absence rates. Also, the machinery in your business will stay well-maintained as the excess dust will be sucked up by the downdraft bench, which results in less wear and tear of theequipment.
The filtration system in a downdraft bench saves energy, which means you will never face a heavy electricity bill because of this system. Also, if the contaminants are filtered away from any machinery in your industry, they will not be clogged and will function well and last longer.
The downdraft tables will not only clean your work environment, but also raise the effectiveness of your machinery. The majority of these tables work on filters that are easily maintained, and these also don’t need replacing so soon. Again, this will save you money.
To sum it all up, these downdraft tables have many advantages, which will always improve the health and safety of you, your employees and your equipment. | mechanical_engineering |

Although we are in a special period of development and face many difficulties and challenges, with our own capabilities and a huge consumer market, we are fully capable of overcoming difficulties and jointly embracing a new era of steel development." On November 25, the 19th China Steel Industry Chain Market Summit was held in Beijing, and He Wenbo, Party secretary and executive chairman of China Iron and Steel Industry Association, delivered a keynote speech entitled "Considering the situation and System Planning to effectively Promote the transformation and upgrading of the steel industry and high-quality development", sharing his thoughts on the future transformation of the steel industry.
The picture shows He Wenbo
China's steel industry should make positive efforts to take the road of carbon neutrality
In his speech, He Wenbo first introduced the five work that China's steel industry is accelerating in terms of green and low-carbon:
First, ultra-low emissions. "Our environmental standards are already among the best in the world, and environmental technical and economic assessments are ongoing." "We won the blue sky battle, and then we have to win the market battle," Mr. He said. The second is extreme energy efficiency. He Wenbo said that low-carbon development should start from the foundation and start from the data. Since its official launch in December last year, the extreme energy efficiency work has been progressing smoothly, and more and more enterprises have entered the ranks of energy efficiency standards. The third is to launch the work plan for the revision and upgrading of China's steel carbon neutral vision and technology roadmap, including the deployment and implementation of breakthrough cutting-edge low-carbon technologies, to keep pace with the green development of steel in the world. The fourth is to improve the environmental product declaration (EPD) platform of the steel industry, achieve the effective accumulation and openness of environmental data of the industry, and actively promote international mutual recognition. Fifth, accelerate the research process of low-carbon emission steel standards, and play China's role in the process of green development of steel in the world.
He Wenbo believes that the three forces from "government requirements, standard constraints and user orientation" have prompted the steel industry to accelerate the development of green steel (low carbon emission steel or near-zero carbon steel) in the green transformation. To be specific, the first is the request of governments, including China and other governments and international organizations; The second is the standard constraint, including all kinds of newly created and emerging new standards; The third is user-oriented, from some leading industries and leading enterprises at home and abroad. "The steel industry is the main force for China's economy and society to achieve comprehensive green transformation, and China's steel industry should actively pursue the road of carbon neutrality." He Wenbo said.
China's steel development environment faces three challenges
He Wenbo introduced that the current development environment of China's steel industry faces at least three challenges:
First, the market pressure, the market environment has changed. He Wenbo said that the steel industry in developed countries has gone through such a stage decades ago, has basically adapted, and our way of thinking has not really jumped out of the environment of continuous expansion of the market, coupled with the concentration of China's steel industry is still significantly low, this "soft and hard" two significant defects on the efficient operation and high-quality development of China's steel industry has formed constraints.
Second, environmental pressure, environmental requirements have changed. "The global steel industry, including China, is vigorously promoting low-carbon transformation, but China's steel industry is implementing the dual tasks of reducing pollution and carbon simultaneously." He Wenbo said.
The third is cost pressure, the basis of competition has changed. He Wenbo believes: "Although China's steel through continuous reform and transformation continue to improve efficiency and improve costs, but the gradual increase in labor costs and environmental costs is an inevitable trend, the era of relying on costs to win the world has passed."
Faced with challenges, innovation is the only way to go. "So we say, innovation is not easy, but there is no alternative. And it requires not only technological innovation and management innovation, but also institutional innovation and governance innovation, which is a challenge for business management and industrial governance of the government." He Wenbo stressed.
"Although facing the above challenges, China's huge market base and the upgrading of demand in new downstream areas and the comprehensive improvement of the environment have provided a new development foundation for the development of steel, as well as the talent group accumulated in the long-term rapid development of the steel industry, which is a solid foundation and reliable guarantee for us to overcome difficulties and cope with challenges." He Wenbo said.
The transformation of the steel industry is essentially a green transformation
"The 'three processes' of urbanization, marketization and internationalization have achieved the world status of China's steel industry, and the two constraints of resources and environment have forced the rapid transformation of China's steel industry." He Wenbo shared his three insights on the overall transformation of China's steel industry.
First, the transformation of the steel industry is essentially a green transformation. "This is determined by the fundamental role of the steel industry in the national economic system and the high-load energy characteristics of the industry itself." He Wenbo said, "The green low-carbon steel through and cover the whole process, the whole industry, everywhere in the use of steel, if the steel is not transformed, the entire industrial system is difficult to achieve green low-carbon."
Second, the fundamental question of green low-carbon transformation is at what cost to achieve the transformation goal. "The degree to which steel is carbon neutral is also determined by the cost tolerance. Various low-carbon technologies are constantly being developed, whether they have vitality and whether they are accepted by the industry depends on the balance between technical possibility and economic feasibility. How to achieve the green transformation of the steel industry under the premise of effectively fulfilling the industrial mission and continuously maintaining and enhancing the industrial competitiveness is a major issue we must face." He Wenbo said.
Third, the green transformation of the steel industry is a systematic project, a social project, not only the steel industry itself. He Wenbo proposed that on the basis of the existing policy framework, a package of overall transformation plans that can fully support industrial transformation and effectively support the realization of national climate goals should be planned.
It is necessary to correctly understand and handle the eight relationships of steel layout
In order to cope with the future complex situation, He Wenbo proposed that it is necessary to correctly understand and deal with the eight relationships of steel layout. These eight relationships can be briefly summarized as "more and less, big and small; In and out, inside and out; Sea and land, long and short; The relationship between country and people, iron and carbon.
"More and less" refers to the more and less production capacity relative to demand, and studies the most basic supply and demand relationship in the market economy, discussing production and consumption, supply and demand. The frequently mentioned problem is how to deal with "overcapacity" and the goal of pursuing "supply and demand balance". In the long cycle of rapid growth and continuous expansion of steel demand, China's steel has strongly supported the rapid development of China's economy with its strong and rich production capacity. With the increasing maturity of the national economic system and the changes in the industrial structure and consumption structure, the trend of continuous growth of the total social steel consumption has changed periodically. The main contradiction in the industry has shifted to how to meet the limited steel demand with sufficient steel production capacity. There are many ways to solve the imbalance between supply and demand, and both governments and enterprises can make a difference, but the experience of the steel industry in developed countries over the decades shows that this will be a difficult process and a historical stage that must be passed, and we must have a clear understanding of this. He Wenbo said that our current task is to do our best to create a "new mechanism for production capacity management", give play to the institutional advantages of China's socialist market economy, and adapt to this historic change in supply and demand in as short a time as possible.
He Wenbo further explained that the new mechanism of production capacity governance we are talking about is: the gradual formation of both environmental, energy efficiency, carbon emission policy constraints, industry self-discipline, government supervision, in line with the law of the market, conducive to the transformation and upgrading of oriented industries and the survival of the fittest, guaranteed, flexible supply and demand balance adjustment of the new mechanism.
"Big and small" refers to the size of the enterprise relative to the size of the market, the study is the degree and way of industrial concentration on the market order and fair competition, fair trade. He Wenbo said that it is clear that China's steel is still in a state of excessive dispersion and industrial concentration is obviously low, and further measures need to be taken to vigorously promote the joint reorganization of enterprises, which is the key to all problems. Therefore, "Creating a new mechanism for capacity governance" and "optimizing new policies for joint restructuring" are listed by the association as the two basic initiatives for the steel industry to span the market cycle.
"In and out." "In and out." "These two relations are closely related issues, two sides of the same problem of internationalization and globalization, which mainly study the investment and trade policies of countries and the international business behavior of enterprises." He Wenbo specifically mentioned that due to the previously mentioned resource constraints and environmental constraints, China's steel does not have the conditions to maintain a high proportion of exports, but must encourage and support the export of high value-added products, steel enterprises must be encouraged to develop long-term cooperative relations with downstream leading enterprises on a global scale, which is an important source of power for enterprises to continue to maintain technological innovation.
He Wenbo believes that there are three driving forces for product exports, one is market-driven, the second is supply chain driven, and the third is industrial investment driven. The market drive is mainly price driven, while the investment drive depends on the investment intensity of the steel and downstream industries in the countries where they are invested. The export of high value-added products highlighted above currently mainly refers to the export of products driven by the supply chain. In recent years, the product structure of China's steel exports has been continuously optimized, reflecting the results of the overall technological progress of the steel industry, but the international market competition is fierce, various tariff and non-tariff barriers and trade discrimination are increasingly common, and it is crucial to strive for and create a fair competitive environment for Chinese enterprises.
In his speech, He Wenbo also talked about how to implement the key work idea of "continuously promoting the internationalization process of China's steel" proposed by the industry and the work arrangement for next year, and combined with various problems and suggestions put forward in the recent exchanges and communication between the association's leaders and various international organizations, and put forward relevant suggestions on the principles of overseas green steel investment.
"Sea and land," "long and short." He Wenbo said: "These two topics study the spatial layout and process layout of the steel industry, discussing the layout of steel in the coast and inland, and the layout of long and short processes."
He Wenbo revealed that as of now, the steel production capacity within 100 kilometers near the coastline has reached 380 million tons, and with the production of some projects under construction, the coastal steel production capacity will reach 400 million tons. According to the requirements of the coastal steel layout issued by the national ministries and commissions, we believe that the purpose of adjusting the layout of the coastal steel production base has been achieved and the task has been completed. He Wenbo believes that with the development and utilization of inland resources and renewable energy more and more attention, according to the perspective of "economic, ecological, and safety three-dimensional dynamic assessment", the value of some inland steel should also be re-recognized.
At present, the short process production capacity of electric furnaces accounts for 16.7%, and the actual crude steel output in 2022 accounts for 9.5%, indicating that the actual input rate of electric furnaces production capacity is low, and the Ministry of Industry and Information Technology and the Steel Association have further promoted the application of short process as a key work topic. He also mentioned in particular that the current concept of long process and short process can not fully cover the layout of the process of steel, including hydrogen reduction, including some new low-carbon processes have been developed, iron and steel processes have brought different combinations of new changes in the process, it is necessary to pay attention to the new development of such third processes.
"Nation and people," "Iron and carbon." "State and people" refers to the proportion and combination form of state-owned capital and private capital in the steel industry, that is, the capital layout problem in the steel field. "This is not a problem unique to the steel industry, is beyond steel issues, here will not be discussed in detail, but the capital layout and spatial layout, process layout, is an important part of the layout of the steel industry." He Wenbo went on to say that "iron and carbon" is not an independent issue, but is almost related to the above issues, and can be divided into broad "iron and carbon" and narrow "iron and carbon".
He further explained that the broad definition of "iron and carbon" refers to how to deal with the relationship between steel production and carbon reduction. "This is also an important issue that has attracted more and more attention and weight in the development and planning of steel in recent years, and has more and more substantial impact on the long-term development and overall layout of the steel industry." 'he said.
He Wenbo introduced that the narrow "iron and carbon" study is the specific "iron cycle" and "carbon cycle". In particular, he spoke of rethinking the "carbon cycle". Everyone is relatively familiar with the iron cycle, but the understanding of the carbon footprint accompanying the iron cycle is far from enough, as the new low-carbon process is gradually clear, the acquisition and supply of iron resources and its product form, including steel and mining industry boundaries will change. The "Cornerstone Plan Upgrade" proposed by the Association is mainly to propose an updated version of iron resource solutions in response to this new change. In this sense, the "Cornerstone Plan" is not only a resource guarantee plan, but also an industrial chain cooperation plan, and a future-oriented green resource development plan.
"In the face of complex economic situation and volatile international situation, we must adhere to systematic thinking, overall planning, complete and accurate comprehensive implementation of the new development concept, look at the direction, maintain strategic focus, and jointly promote the transformation and upgrading of the steel industry and high-quality development." He Wenbo said. | mechanical_engineering |

Renault wanted to activate their partnership with En Svensk Klassiker and asked us to help the race participants to elevate their performance to the next level.
Today, Swedish amateur athletes want to train, eat and dress like professionals.
However, there is one thing that amateur athletes still have left to learn from the elite; mental training.
In a new experiment called Team WillPower, Renault challenged three athletes to drive a Renault KADJAR – using only willpower.
After extensive mental focus training, came the ultimate test – to control and steer a car together.
More than 150 million people all over the world were reached.
But most important, we encouraged thousands of En Svensk Klassiker participants to train like professionals – focusing on mental strength, as much as the physical.
We re-built a Renault KADJAR, making it possible to drive it using only brainpower. The three athletes mental journey was documented in a film, from start to finish – from the series of mental focus exercises with the coach and triathlete Jonas Colting, to the actual experiment where the participants were equipped with emotiv-headsets and the mission to each control their important part; turning right, turning left and accelerating.
When launching, we invited journalists to test drive the re-engineered Renault KADJAR to experience the experiment – at own risk.
We also made four short films with Jonas Colting, where he gave his best mental tips for each of the four races that ESK consists of; skiing, biking, swimming and running – giving ESK participants a chance to take their performance to the next level.
To control the car with brainpower, we first needed to build a ‘driver’ that the brainwaves could control.
This mechanical chauffeur needed to be portable and fairly lightweight, so we chose to have it replicate a human by giving it two legs and a hand. The “legs” consisted of two linear servos, one for the accelerator and the other for the brakes. For the “hands”, we used the chain and sprockets from a gokart, connected to a DC servo motor. Each servo is controlled by a Raspberry Pi3 whom are given commands from a server running on a regular laptop.
The EEG headsets which the athletes wear are connected to the server-laptop via bluetooth and are given a specific objective: steer left, steer right or set speed. Each driver then view LED’s mounted on top of the dashboard to see how well they are performing – hence determining if their designated command will be executed.
The entire system is powered by a regular 12V car battery. | mechanical_engineering |

If you recall, we don’t own a car. In small towns in this part of México, a golf cart is sometimes called a carrito, and functions for many, such as Jon and me, as a little battery-operated car. We depend on our golf cart to get us to the mini-supermarket, produce stand, and meat market to shop once or twice a week. It hauls three loads of laundry in the three blue Rubbermaid totes strapped to the back when we drive it to the lavandería once or twice a week. We load our paddleboard onto the custom top rack and our beach gear on the back when we head to the beach for some Stand Up Paddleboarding. This inexpensive vehicle does a lot of work for us.
|Three Rubbermaid Totes & a Cargo Net Hauls a Lot of Stuff|
What could be wrong? Jon was faithful about filling the six battery water reservoirs with distilled water. He always charged the batteries after every trip to town. When we got home that day, he tested the batteries with his volt meter and found one of the six well-used batteries was no longer holding a charge. We didn’t have it in our budget to buy six new 6-volt deep-cell batteries at the time. So, Jon asked around at a couple of golf cart rental places in town to see if he could buy one used battery to get us by. There were none to be found. We decided we would pick up a used battery while we were in the U.S. and hope that would fix our power issue.
|We Were Back to Riding Bikes to Town Again|
We really missed our carrito! But, there was nothing more we could do for it until we returned from our travels to Oregon. We unplugged it from the battery charger, covered it with a tarp to protect it during the rainy season in Nayarit, and called a taxi to take us to our motorhome. We knew when we returned in the fall, golf cart repairs would be a high priority.
When we returned from Oregon, Jon had a “new” used battery and wasted no time installing it and attaching the charger to the carrito. But, the six batteries would not come to full charge. It was time to find a golf cart repairman. I had remembered one of my Facebook friends, Gabe, had recently posted a photo and information about a golf cart expert who works at two golf courses in the Riviera Nayarit. So, I did some digging on Facebook (what a wealth of information that social media provides!) and found his name and phone number.
|Ari and His Wife Checking the Batteries|
Ari then mentioned that the ball joints and brakes were badly worn, the steering was loose and mushy, the brakes barely functioning. He said that he could fix those, too. Jon said he knew they were in pretty poor condition and asked for a price to have them rebuilt. Ari gave him a fair price to do the work and came the next day as promised. He arranged his supply of parts and his tools and set to tearing the front end off of our golf cart. The poor, dirty thing looked pretty sad without its front tires and other key parts disassembled. When I looked at the disabled carrito propped up, sitting on its tires that were lying on their sides in the gravel, I thought, “That’s one way to jack up a vehicle. I guess that’s how they do it here in México.”
|Ari Working on the Golf Cart's Ball Joints & Brakes|
|Jon Straps the Paddleboard Onto the Carrito for a Trip to the Beach|
Now for the bad news. The auto repair shop does not repair golf cart tires. Jon insisted that there had to be a way to fix it because we couldn’t get home otherwise. The young man thought about this for a few minutes, shook his head, and then wandered off, leaving Jon and me wondering what we were going to do next.
A while later, he sauntered back to Jon with a full-sized automobile inner tube in his hand, deflated and old. He said, in Spanish, that he had an idea. We watched in amazement as he proceeded to pull the golf cart tire off, stuff the wad of tube into the tire, and reinstall it on the carrito. He then attached his air compressor to the tube stem and began adding air to the inner tube until it inflated just enough to fill the golf cart’s tire. Fixed! The amazing thing is that in the year since that ingenious repair job, the tire has never gone flat.
Our carrito’s tires may be old and bald, but we don’t have to climb extremely steep hills. The tread is about gone and the batteries don’t have the power Jon would need to “peel out” anyway, so why change the tires yet. The Mexican way is to use things until they stop working, and then fix them so they will work a while longer. Living in México, we have learned some great lessons on how to live frugally!

January 26, 2011
When laying out coordinated grids on paper, I used to find it rough going trying to divide odd numbers of inches evenly, or vice-versa. It's important that these lines be accurately placed if you're trying to use the grid to transfer a thumbnail sketch you made, or represent proportion correctly when working from a photo. I happen to have studied a bit of drafting, and discovered a wonderful little tool used by draftsmen, sea captains, and metalworkers alike. It's a pair of dividers, sometimes called compass-dividers, the same thing as a compass with a second hard point instead of a pencil or pen. (You could use a regular compass for the following, but you may end up making some unwanted marks.)
Let's say I need to divide a an 10” x 12” sheet of paper into a 3 by 5 block grid. I start by adjusting the legs of the dividers to approximate 1/3 of the 10” width of the paper; (by the way, there is a “proper” handhold for adjusting/using the dividers, but I generally don't bother with it). I then “walk” them along the 10” edge of the paper, twisting them back and forth with each step in the conventional way until I reach the corner; (see picture). Chances are, I won't hit the corner exactly on the first try, but I note by how much I overshot or undershot it; (see photos).
The last “step” of the dividers will tell the story. If the point has ended up hanging off the paper onto the drawing board, I note the distance between this point and the corner of the paper. I then close the dividers by approximately 1/3 of this distance and try again. If instead, I find I've closed them too far, I open them by about 1/3 of the shortfall. When the last "step" of the point touches the edge of the paper exactly, I walk them along the edge again, this time making a tiny pencil mark right next to each point as it comes down.
It makes sense to step off the other 10” edge at this time, while the dividers are set at the correct distance for it. After marking off the 12” edges in the same way, all that's left to be done is connect the lines with a ruler.
As with many tools, it takes a little patience to get the hang of it, but I still prefer it to trying to measure off thirds of an inch, or seeing if I can find an easier dividend for the length I'm dealing with, (which might produce sectors of less than ideal size).
There are some other possible artistic uses for this versatile tool, such as:
- Dividing a picture into "rule of thirds" sectors.
- Symmetrically locating fence posts.
- Comparing elements within a picture, based on an arbitrary unit, such as “eye lengths” in a head-portrait, or “rocking-chair-heights” in a porch scene, (perhaps using two pairs; one for the painting, the other for the reference photo). | mechanical_engineering |

These windows have come a long way since their inception in the mid-20th century, and their evolution reflects the growing concern for safety and durability in construction.
The earliest hurricane windows were made of glass laminated with plastic, which could resist breaking when hit with a blunt object. This type of window was first developed in the 1950s, in response to the growing frequency of hurricanes and the resulting damage to homes and buildings. However, these early versions were heavy, expensive, and not very effective in protecting against high-speed winds.
In the 1970s, new manufacturing processes enabled the production of lighter, more affordable hurricane windows. These windows were made of multiple layers of tempered glass and plastic, and they could resist the force of a Category 3 hurricane (wind speeds of up to 129 miles per hour). These windows were an improvement over their predecessors, but they were still limited in their ability to protect against the most severe storms.
The 1990s saw a major breakthrough in the development of hurricane windows, with the introduction of interlayer technology. This technology involves placing a layer of polyvinyl butyral (PVB) between the layers of glass, which creates a strong, flexible bond that can absorb impact and prevent the glass from shattering. This innovation greatly increased the strength and durability of hurricane windows, making them more effective in protecting against Category 5 hurricanes (wind speeds of up to 157 miles per hour).
Today, hurricane windows are an essential feature of homes and buildings in hurricane-prone regions, such as Florida and the Gulf Coast. They are designed to meet strict building codes and are tested for impact resistance using methods such as the Large Missile Impact Test and the Small Missile Impact Test. Hurricane windows come in a variety of styles and materials, including vinyl, aluminum, and fiberglass, and can be customized to match the aesthetic of any home or building.
In addition to protecting against hurricane damage, hurricane windows offer other benefits as well. They can reduce energy costs by providing better insulation and reducing the amount of UV radiation that enters a building. They also offer improved sound insulation, which can be beneficial in noisy urban areas.
In conclusion, the history of hurricane windows reflects the ongoing efforts to improve safety and durability in construction. From the early laminated glass to the latest interlayer technology, hurricane windows have come a long way in protecting homes and buildings from the devastating effects of hurricanes. As the threat of severe storms continues to grow, these windows will undoubtedly continue to evolve and improve. | mechanical_engineering |

In 1783 the "Montgolfier brothers" in France succeeded in launching a hot-air balloon. The balloon was the first aircraft in the history of mankind. The principle of the hot-air balloon, which uses the heating of air to create carrying capacity, has remained the same since then. Just one month later, Professor Charles invented the hydrogen-filled gas balloon. For a long time, it was the only air vehicle with which people on Earth could float away. No suitable, incombustible and light material had yet been found for the envelope of the hot-air balloon. But this changed abruptly in the 70s when nylon and polyester were invented: Today, the balloon is an absolute "high-tech device" made of expensive materials, which, in combination with the good training of the pilot, guarantee a safe flight. Today, the gas balloon is used less often due to the much greater effort involved. The Montgolfiere (hot air balloon), on the other hand, has conquered the skies today. Would you like to experience an unusual adventure and at the same time enjoy wonderful moments of relaxation? Then try the Montgolfier brothers. Experience the tranquillity and incomparable fascination of free floating with a balloon ride, a journey in a wicker basket; the cradle of the air. | mechanical_engineering |

Authorities plan to extend this safety initiative
Convex mirrors have been introduced in North Bengal’s Naogaon district, marking a novel approach to enhance road safety at perilous bends.
The local community in Naogaon is optimistic that this innovation will extend to other district roads, promoting safer highways and regional routes.
According to sources at the Naogaon Road Department, an initial experiment saw the installation of 20 high-quality convex mirrors across a 54 km stretch of the Manda-Niyamatpur-Shibpur-Porsha highway.
These mirrors are constructed from premium imported fiber and aim to address safety concerns on a 25 km section notorious for dangerous curves.
With these mirrors, drivers and pedestrians approaching these critical 90-degree bends can now observe oncoming traffic from both sides, ensuring secure navigation.
Individuals are now safely maneuvering these bends with confidence, eradicating the previous risk of head-on collisions during both day and night.
The Naogaon Road Division plans to extend this safety initiative to other high-risk bends on highways across the district.
Akkas Hossain, a resident of Niamatpur upazila, shared his experience, emphasizing the hazardous nature of the Niamatpur-Shibpur road due to its sharp bends. He noted the significant improvement since the installation of these mirrors, with accidents reduced substantially.
CNG driver Rubel, hailing from Sapahar Upazila, also applauded the initiative.
He explained how the mirrors enable drivers to anticipate oncoming vehicles, ensuring safer passage through the bends. This measure has notably decreased accident rates on these treacherous stretches.
Naogaon Road Division Executive Engineer Rashedul Haque Russell said: “The experimental effort aims to fulfill Prime Minister Sheikh Hasina’s vision of constructing durable and secure roads. The high-quality fiber mirrors, thoughtfully installed at accident-prone bends on the Manda-Niyamatpur-Shivapur-Porsha highway, are designed to endure sun exposure and prevent cracks.”
He said with the community’s cooperation in maintaining these mirrors, the mirrors are poised to enhance road safety for years to come.
The Road Division is committed to extending this road mirror initiative to other hazardous bends on highways across the district in a phased manner, he added.

And these have to be in tune with your swing speed, handicap, etc.
Now golf balls are pretty much the same after all, it’s not just a round, tiny thing built out of nothing. Even though that’s what it looks like on the outside, there’s a lot of going on inside that is responsible for crucial factors like distance, spin, etc. And one such aspect of the construction is golf ball compression.
It’s the compression rating that categorizes golf balls as slow-swing-speed-friendly or Tour-grade.
But then you should also know that compression used to be more important a few decades ago. Now the scene has changed because not all golf ball manufacturing companies use the same standard for measuring compression ratings. So let’s get to know more about this and also about what the compression of a golf ball actually means.

What Does Golf Ball Compression Really Mean?
When the clubface comes in contact with the golf ball, the latter is compelled forward by the former through compression. Your golf club literally sets the ball in motion by interacting with its core (the core is like an engine that carries the ball long distances) and simply compressing it on the point of impact.
Now let me talk about how slow/fast you strike the golf ball. This would mean golfers with a fast swing speed can hit that ball harder at impact. Hence, higher compression of the golf ball, so it recoils properly without breaking apart because of the high-speed, hard impact.
Low Compression Golf Balls
80 compression golf balls or below are labeled as low compression. These have the softest core for a greater rebound at impact, which makes the balls travel much farther than their high-compression counterparts.
But then, comparatively speaking, you also cannot expect the former to create a straight flight path like the latter. Thus, control is not a part of a lower compression rating.
- Soft-core golf balls.
- Easily compressed, so no need to swing fast or hard for core activation.
- With low compression, maximizing distance with a slow swing speed is very easy.
High Compression Golf Balls
The opposite of low is high, which would mean these golf balls are played by the fastest and hardest hitters.
These are 100 compression golf balls that maximize accuracy above all else.
- Hard-core golf balls.
- Slow to compress, so a hard swing is required for core activation.
- With high compression, you can maximize distance with a fast swing speed.
Medium Compression Golf Balls
Here the compression rating is about 90. And they give you the best of both worlds i.e. distance (of low compression) and control (of high compression).
- Average core, standard golf balls.
- Neither the softest nor the hardest feel, somewhere in between. Hence, fit for a wide range of golfers.
- With medium compression, distance is maximized with an average or standard swing speed.
How Does It Affect Your Game or How You Play?
If you just apply simple logic, you’ll understand that fast-swing players compress the golf ball without even trying to do that. Therefore, it’s easy for them to achieve maximum distance because the ball jumps right off the clubface.
On the other hand, slow-swing golfers as it is struggle with their swing speed, so compressing the golf ball is a whole other problem for them. Thus, resorting to low compression golf balls is becoming more and more common these days since this type of construction helps to maximize every slow swingers’ distance potential.
But then if a high-speed player uses low compression, he/she cannot really benefit much (although it doesn’t necessarily hurt the game). It just means that all that extra speed and energy you have as a faster, more proficient golfer will only go to waste and not be utilized to its max limit by high compression.
But How Exactly Does A Golf Ball Produce More or Less Compression?
It All Depends On Your Swing Speed
When your swing speed is faster, the clubface meets the golf ball with more force at the point of impact. So the ball compresses more, therefore high compression golf balls are a must.
By the same line of reasoning, one with a slower swing speed then requires a lower compression rating to make the golf ball compress like it should for yielding longer distances.
Golf Ball Also Compresses More or Less Depending On Its Core (not cover)
Naturally, a harder or firmer core compresses less while a softer core golf ball compresses more.
So what really happens when the ball compresses more? A higher level of energy is transferred to the golf ball from the clubface. The result of which is the ball springing off the face and generating maximum distance.
And now here’s the other side of that explanation. When there’s less compression at impact, less energy is transferred to the golf ball. And that is exactly what fast-swing players look for. For them, hard-core golf balls are the best precisely because high-speed golfers don’t exactly need that additional energy transfer; they’re quite capable of producing that on their own because of their faster swing speed.
Now please note that I’m referring to the core of the golf ball here, and not its cover. Many use both terms interchangeably and that could be misleading. Golf ball core and golf ball cover are two separate things. The inner core is the compression. And the cover is actually the very factor that determines its hardness, which has nothing to do with compression rating as much as it does with the feel of the ball.
Hard-cover golf balls are low in terms of feel with lower spin and green-stopping power.
Soft-cover golf balls give you more feel with higher spin and green-stopping power.
Who Do They Say That Compression Doesn’t Matter Anymore?
I get why the compression rating of a golf ball has now become a sort of an outdated approach.
Since we’re now living in the 21st century, golf clubs and golf balls have been subjected to SO MUCH technological advancement that there are many other traits besides compression in golf balls that can give you the upper hand. Technologies, materials, you name it!
Because Brands Hardly Mention Compression Ratings
Companies that now manufacture golf balls rarely reveal compression ratings. Instead, they focus more on informing golfers across all spectrums about modern manufacturing processes and the use of advanced materials, and stuff like that.
Speaking of which, modern-day golf balls, and this goes without saying, don’t feel the same anymore. As a Senior Tour player now, I can tell you for sure that they don’t. A 70 compression golf ball can now easily pass off as a 60 compression rating, in terms of “feel” of course.
Because There Isn’t Any Universal Compression Rating Test
Compression ratings are not tested in any given manner. Every manufacturer out there uses its own rule or standard for testing the compression of golf balls. Here, let me explain.
The ball is subjected to static pressure, which causes it to deform. But then how much static load is applied? What is a standard load to begin with? Not every brand uses the same static load after all.
By that logic, golf balls with a compression rating of 60 from brand A can be the same as those with a 70 compression rating from brand B or a 55 compression rating from brand C.
So What Compression Rating Works For YOU?
Low compression (80 or below) or high compression (100 or above)? Or something in the middle (around 90)? Well, it all depends on what your swing speed is. So have you measured your swing speed? If not, here’s to go about it.
If your swing speed is 85 mph or less
Then you need low compression golf balls. Only a lower compression rating, at this point, allows you to achieve the extra distance or yardages you have in mind.
If your swing speed is between 85 mph and 104 mph
Choose medium compression golf balls if you have an average swing speed. Because a lower compression rating will jeopardize control. And your swing speed isn’t fast or hard enough yet for a higher compression rating.
If your swing speed is 105 mph or more
Nothing works as perfectly as high compression golf balls. These give you good distance as well as control. Whereas mid or low compression, even though they may boost distance, is only going to produce too high launch and too much spin that you simply cannot control.
I would also like to add here that the compression of a golf ball is not the only thing that determines the distance. Other factors like golf ball cover, core, mantle material, and dimple pattern also play a significant role.
Also, don’t be under the impression that golf balls that travel farther are always the right choice FOR YOU. Not every golfer, after all, prioritizes distance. For some, spin, flight, or feel are more important.
How Long Does Golf Ball Compression Last?
Golf balls, in general, are fit to play for about 7 rounds of 18-hole golf. And when left unused (room temperature storage), they can preserve their original condition for around 10 years. The same can be said about the core and compression of golf balls.
If you ask me, losing your golf balls is more likely than they actually becoming obsolete over a period of time.
Does Your Swing Speed Decide Which Golf Ball to Choose?
If it were otherwise, I don’t think I would be writing this article for you. It’s precisely your swing speed that your whole golf ball selection is based on.
Golfers with a slower swing speed need a lower compression rating to get the golf ball to spring harder off that clubface. Conversely, players with a faster swing speed use high compression to gain more control over the ball.
What Role Does Weather Play In Golf Ball Compression?
When the weather is cold, high compression golf balls are bound to feel as hard as a rock. So it’s best, at such times, to use low compression golf balls to make way for more flexibility off the clubface.
As it is in cold weather, compression apparently decreases. So it only makes sense to choose a lower compression rating.
How Is the Compression of Golf Balls Measured?
It’s the extent to which a golf ball is compressed when a certain weight or load is applied to it. The compression ratings start from zero and go all the way up to 200.
When the compression is at zero, it means that the golf ball compresses the most at two-tenth of an inch. While 200 implies no compression at all. Each compression point, by the way, is equal to 1/1000th of an inch.
Do Lower Compression Golf Balls Travel Longer?
A lower compressing rating means the golf ball is easily compressed, hence greater transfer and release of energy at impact. As a result of which the ball certainly travels farther in comparison to higher compression.
Who Should Be Using Low Compression Golf Balls?
More often than not, the longest golf balls that obviously have the lowest compression rating are quite popular among slow-swing golfers (below 85 mph). Such as beginners, seniors, and amateurs.
But this doesn’t mean you cannot use one of these as a better, faster-swing player; it’s just that you won’t be able to gain maximum distance with lower compression.
Who Should Be Using High Compression Golf Balls?
That would definitely be golfers with a fast swing speed (above 105 mph). Only the better players can compress the golf ball less and still be able to maximize distance, control, AND feel.
How to Choose the Right Golf Ball for My Swing Speed?
It’s as simple as taking numbers and analytics into account:
When your swing speed is <85 mph and you have a high handicap, pick 2-piece, low compression golf balls.
When your swing speed is between 85 mph and 104 mph with a mid-handicap, go for medium compression, 3-piece golf balls since they’re the best for distance, feel, and control.
And when your swing speed is >105 mph and you have a low handicap, choose nothing but multi-layered, high compression golf balls.
What Compression of Golf Ball Works Best for Slow Swing Speed?
Once again, if your swing speed is slow i.e. 85 mph or lower, you should be using only low compression golf balls. These would be those that have a 70-80 compression rating. Only then will you be able to produce longer yardages with better feel off the clubface.
Are Higher Compression Golf Balls Better?
Well, YES they are better, but for better players. If your swing speed is fast and hard, you don’t need the golf ball to compress a whole lot in order to produce more distance.
On top of that, a higher compression rating in a golf ball hands over greater control, which is just what better golfers demand.
Should Beginners Use High Spin or Low Spin Golf Balls?
As a beginner highly prone to hooking or slicing your shots, you should be using low spin golf balls (generally, these are also low compression). Because with high spin golf balls, the chances of hitting slices and hooks get maximized. So unless you, as a beginner, can produce a straight ball flight, go with lower spin.
The End Is Here!
Check the packaging of the golf ball to get to know its compression rating. It must be printed somewhere there in the description. It’s going to be a number between 70 and 110, in most cases at least.
As for summing it up:
- Choose low compression if you have a slow swing speed. While a higher compression rating is better if your swing speed is faster.
- Compression is actually how much a golf ball is squeezed or compressed at impact.
- Factors that decide how much compression occurs include your swing speed and the core of the ball.
- You have to make sure your swing speed is what determines the compression rating that works for YOU.
- And lastly, the weather does indeed have an impact on the compression of a golf ball.
In the end, I would also like to add that do not overestimate the importance of compression. It is ONE of the factors that guide you through the whole journey of choosing the right golf balls for yourself, not the ONLY factor. | mechanical_engineering |

This latest iteration of Subzero is a tour de force of how advanced design and technology can come together to create superior sound quality. All aspects of the design have been perfected to the smallest detail, resulting in truly revolutionary woofer performance. Subzero is capable of an incredible 2.5"excursion (10" Subzero). With excursion of this magnitude, Subzero produces levels of bass unattainable by conventional woofers. The extreme excursion ability coupled with the unique suspension makes Subzero extremely transient proficient. Even a light touch on the cone, easily moves it several centimeters. This ease of movement combined with the ultra-powerful magnet system results in a spectacularly fast and precise response. Subzero is free of the mechanical and electrical constraints inherent to common woofers.
Lava-fused Octo Helix voice coil
Subzero is equipped with a unique voice coil of oversized proportions. All aspects of the voice coil design are optimized for maximum performance, durability and sound quality.
In the creation of the Subzero voice coil, Earthquake scientists have boldly challenged the very genesis of the voice coil itself.
Traditionally, a lot of effort goes into choosing the right voice coil former (the cylinder to which the coil is wound). The former must be light, have similar heat expansion properties to the voice coil and it must promote cooling. Constantly advancing the state of the art, Earthquake engineers theorized that the best solution must be to have no former at all. While this theory flies in the face of all conventional wisdom, our engineers pressed on. During this proof-of-concept phase, it was realized that the technology needed to do away with the former simply did not exist. Instead of abandoning the quest for formerless technology, the research was extended to include facilitating technologies. In place of the structural support provided by the former, a super strong ultra high temperature adhesive was needed. A new insulator for the coil wire was also needed as traditional lacquer insulator does not have sufficient bonding properties for it to fuse together at the required tensile strength. This challenge was constructive in its own right as the biggest threat to woofer survival is heat, if the essence of this new technology would bring forth a temperature resilient voice coil it would serve to improve all other aspects of woofer operation.
The creation of the needed high temperature adhesive proved difficult and the next break would come as an unlikely discovery by our Chief engineer while on vacation in Hawaii. Taking a scenic tour of Hawaii, he was walking through an area with volcanic ash and realized that the ideal base substance for a high temperature adhesive would be a material with no combustible elements left. Volcanic ash fits this description perfectly as it has been exposed to extreme heat - it has been combusted to the point where further heat exposure will not change its molecular structure. The volcanic ash was taken to our German adhesive manufacturing partner and six months later we had our next generation temperature invariant super adhesive. Now we just needed an equally temperature resistant insulator. The only known insulator capable of withstanding this immense heat was anodizing. Anodizing however is problematic because it breaks off the host material if it is bent beyond a certain point. After much experimentation it was discovered that it is possible to prevent the anodizing from breaking off if the coil wire is heated to red hot temperature at the time of winding. Finally, the first former-less voice coil could be made. The audible qualities springing from this new lighter and stronger coil type is nothing less than remarkable.
Signature technologies such as the Octo-Helix winding scheme has evolved for use in the new Subzero. The Octo-Helix design requires a very advanced production process. The Helix design is unique because it allows identical electromagnetic coupling and thermal signatures of two voice coils. In a conventional subwoofer with dual voice coils, they are wound one on top of the other, resulting in asymmetrical electromagnetic coupling and heat dissipation capability. The Helix structure is free of these limitations, since the two coils are wound synchronously in-phase. The Helix wound voice coil is characterized by several obvious advantages - perfect electromagnetic coupling, identical thermal signature, lower distortion, higher performance and durability.
The voice coil is comprised of eight (octo) layers of edge wound oxygen-free copper wire. This special copper wire is of the flat-wire type. Flat-wire has a much greater surface area than conventional round wire and can thus dissipate considerably more heat it. Another advantage is the coil can be wound closer - increasing motor power. The coil assembly meets mil-std specifications for temperature resilience - specifications set by the U.S. Department of Defense for use in military equipment. This guarantees peak performance even during hard and continuous operation.
TCT - Turbine Cooled Transducer
Subzero is equipped with the patented TCT (Turbine Cooled Transducer) technology. TCT creates cooling airflow similar to a tornado around the voice coil. The tornado is created by air forced through cooling channels milled in a vortex structure. Traditional voice coil cooling is done by drilling out the pole piece and the woofer stroke then pushes air back and forth. This cooling scheme only has a linear increase as a function of woofer stroke. TCT is different. TCT creates an exponential increase in cooling capacity as a function of woofer stroke. This is achieved by harnessing the centrifugal forces in the mini tornado to increase surface area contact between the air and voice coil. TCT is so effective that the voice coil temperature is reduced 50% compared to the same woofer without TCT. This prevents heat derived compression and keeps the woofer at maximum efficiency.. The compression is a result of the increased electrical resistance of the voice coil - the higher the temperature, the higher the resistance. Since TCT's cooling capacity increases exponentially with excursion, heat is not allowed to build up. The harder you drive Subzero the more it cools itself.
Poly-Ether draw SWE (Super Wide Edge) suspension
For Subzero our unique SWE (Super Wide Edge) suspension design has been enhanced by the use of Poly-Ether draw material. Sporting an extreme curve height of 62 mm the stage has been set for incredible excursion. The manufacturing of this advanced suspension is a complex process spanning several stages. Poly-Ether draw is used primarily in military applications because of its high strength and flexibility. The sophisticated and costly processing requirements has so far limited its use outside the military. Thanks to the obsessive high-tech emphasis by Earthquake, the entire Poly-Ether draw manufacturing process can be done in-house. As part of the manufacturing process, the Poly-Ether material is thermally pressed and laminated giving it extreme strength and mobility. The suspension geometry is of the single-layer type and allows ultra long excursion without mechanical breakup. This results in woofer stroke potential in excess of 100 mm without deformation or increased mechanical resistance.This ensures perfect reproduction of even the most bass heavy soundtracks
Parabolic deep dish woofer cone
The Subzero cone is made of a proprietary non-pressed fiber reinforced cellulose pulp substance with extreme stiffness. The cone is then superimposed with a parabolic deep dish made of a strong space age polymer that obtains additional rigidity by its geometric shape. The cone does not flex or deform regardless of input power and frequency.
Dual Super-Spider with composite center and symmetric stitched tinsel leads
The Subzero spider is of the super spider type, which means the spider has the same diameter as the cone -this ensures the spider is not limiting excursion. The Subzero is equipped with a double super spider unit comprised of a Nomax /Romax hybrid material that has been epoxy coated for increased strength. The individual super spider units are arranged as identical opposites - canceling nonlinearities inherent to typical single or dual spider designs.The result is a clean sound - free from mechanical artifacts. For optimal performance the edge suspension and spider must have the same excursion potential, this is not possible with a traditional spider of limited diameter.
Traditionally, the spider is glued to the voice coil, this results in heat transfer from the voice coil to the spider. This heat transfer effects the spiders compliance and can over time degrade the spider. The Subzero super spider is not glued the voice coil, but attached to a composite center ring that in turn is bonded to the voice coil. The special composite material is neither heat sensitive nor a thermal conductor. Thus the endurance and longevity of the Subzero is not affected regardless of drive level.
The tinsel leads to the voice coil are sewn into the spider to ensure against collision with the cone during extreme excursion. This also extends the life of the tinsel leads, as they now bend more gently over a longer distance. The symmetrical design of the tinsel leads prevents an asymmetrical pull on the cone. The result is longer woofer life, and greater endurance.
Double stacked Cobalt-Ceramic high gauss magnet system
Subzero is built around a gigantic magnet system. It consists of two huge Cobalt-Ceramic magnets which have been hyper magnetised in-house by Earthquakes military grade Magnetiser. The two magnets have a total thickness of 6 cm, the top plate alone is 1 cm and the pole piece is 5 cm. With a total height of 12 cm - the voice coil is given unhindered travel space far beyond its mechanical limits. This ensures that not even the strongest transient may cause the device to run out of electromagnetic coupling. At the same time the high gap height contributes to voice coil cooling, as the immense mass of metal effectively absorbs heat.
Diamond cut chassis with XLT geometry
The Subzero is based on Earthquakes signature XLT chassis geometry. It is the optimal design for extreme excursion. The XLT chassis allows for extra length between the spider (center suspension) and the magnetic gap. It is designed to accommodate oversized spiders and voice coils.
The Subzero chassis feature another advanced design detail unique to the Subzero. All other woofers have the chassis mounted on top of the magnet. The Subzero encases the magnet within the chassis and the chassis is mounted to the magnet from behind. This special design prevents the chassis from degrading the magnetic flux asserted on the voice coil. The oversized and rigid chassis is made of cast aluminum which is then diamond cut. This results in an ultra-rigid and robust chassis featuring stunning good looks. The chassis is further characterized by all components of the assembly being bolted together with stainless steel machine screws. This design is extremely rugged compared to ordinary assemblies where the chassis and magnet system is often glued and / or tabbed together. The technically superior design ensures exceptional durability, sound quality and pride of ownership. | mechanical_engineering |

What is a Bag Filter?
Bag filters, which are also referred to as baghouses and fabric filters, are instrumental in maintaining good air quality at a commercial or industrial site. Essentially, they are air filters that reduce air pollution and remove particulates from the air. Their performance does not vary widely: a baghouse that is functioning well typically collects particulates at 99% efficiency. This stays true even when the particulates are very small.
Bag filters are usually made up of cylindrical tubes or bags that are made out of woven or felt fabric. This is the filter medium. When the air enters the filter, a cake of dust or other particulates forms on the surface of the fabric. There are three different types of bag filters:
- Mechanical shakers – wide side range, simple design and operation, low air-to-cloth ratio
- Reverse air – allow for continuous operation, cleaned with reverse air flow, rigid rings sewn into the bags to prevent collapse
- Pulse jet – cleaned with a short burst of compressed air, allow for continuous operation, the bag can be changed without having to enter the baghouse
What is the Filter Bag Made Out Of?
The filter bag itself is usually made of cotton, nylon, polyester, and fiberglass, as well as other materials. Both woven and nonwoven materials are used. When the nonwoven material is felted, it is fixed onto a woven backing called a scrim. When the nonwoven fabric is instead a thin, porous membrane, it is bound to the same scrim. Woven materials are usually plain weave, twill weave, or sateen weave, which allows for either an increase or a decrease in the space between individual fibers depending on the type of weave.

Truck tires play a significant role when it comes to hauling freight. In fact, they are one of the most important assets of your truck. Truck tires significantly contribute to fleet operating costs and fuel consumption. A good tire management program can end up saving you thousands as a small business owner, helping you keep more money in your pocket.
Truck tires found on commercial vehicles usually weigh more than 10,000 pounds in Gross Vehicle Weight. Generally constructed of a single steel body ply with three or four steel belts under the tread, truck tires are designed to last hundreds of thousands of miles on their original tread. Afterwards, they can be retreaded and put back into service for many more miles.
More importantly, tires for big trucks play different roles depending on their mounting position. The front tires are used for steering, the trailer tires bear the payload, and the rear tires on the trailer help shoulder the weight of heavier loads while equally distributing energy onto the road itself. Therefore, when a tire is scrapped, it’s usually not a result of the tire itself. It’s often due to preventable problems.
The following includes the suspects of premature tire death, and what you can do to ensure you get the most out of yours.
1. Underinflated Truck Tires
This is the most common factor in tires that are ruined prematurely. According to the American Trucking Associations’ Technology and Maintenance Council, you should be checking your tire pressure once a week. This should take you no longer than 20 minutes and could save you lots of money in the long run.
Just 10 percent underinflation will shorten tread life by approximately 9 to 16 percent. When tires are underinflated, there’s not enough air to properly support the load, which causes heat buildup and results in the softening of the rubber.
To get the most out of your tires, experts suggest tire inflation monitors or using an accurately calibrated tire gauge. Some companies even offer ways to help drivers offset the costs of tires over time. Here at Bennett, we understand the importance of preserving tires for as long as possible, which is why we also offer exclusive tire discounts for our owner-operators.
2. Road Hazards
Unfortunately, the most unpredictable road hazards are the most difficult to manage when it comes to tires. Curb strikes and glass or a nail in the tire often results in having to purchase a replacement. However, you can moderate this issue by getting the proper repairs when applicable. Inspect your tires for this type of damage to prevent a roadside service call.
3. Duels That Don’t Match
Mismatched duels can cause early wear and tear on your truck tires. If there’s an inflation mismatch greater than 5 psi, this means the larger tire will drag the smaller one; for roughly 246 miles for every 100,000 miles driven. The larger tire does the heavy lifting, while the underinflated tire doesn’t make proper contact with the road. This ultimately cases the tire to wear faster. Once again, this problem can be prevented by using a tire gauge to ensure even pressure on the duels.
There are several different types of tire problemsthat result from misalignment including toe-in wear, toe-out wear, full shoulder wear, one-sided wear, feather wear and thrust angle-induced full shoulder wear. Alignment refers to more than just the various angles of the steer axle geometry, but also includes the trailer and tracking of all axles on the vehicle.
In order to check trailers for accurate alignment, you must first measure from the kingpin to the front axle, and then from the front axle to the rear. If the dimensions are nearly identical, this means your truck is properly aligned. Check out this helpful video to see how to properly measure your trailer alignment.
Overall, your truck tires need some TLC to get the most use out of them. However, when you do need new tires, Bennett has great discounts with several of the most well-known manufacturers. Our discount tire brands include Continental, Goodyear, Bridgestone, Michelin, Double Coin and Yokohama.

Process modeling and simulation with ProSimPlus
The objective of this process is to recover LPG (liquefied petroleum gases) with a fixed mass-fraction of methane, from a gas mixture. The main LPG components are hydrocarbons (mainly in the C3-C4 range), propane and butane.
The process utilizes a closed propane refrigeration loop (green streams) around a brazed plate fin heat exchanger.
The description of the process follows.
The initial gas mixture (Methane and LPGs) is sent in a two-phase separator (S101) in order to eliminate the heaviest compounds which are sent to the distillation column (C101). The others leave at the top of the vessel and are cooled in the brazed plate fin heat exchanger (E101). They are then forwarded in another two-phase separator (S102) to separate heavy and lights. The two output streams (stream C03in and C04in) are sent back in the plate-fin heat exchanger as cold streams.
Once treated, the gas is mainly composed of methane and ethane and flows out of the exchanger (stream C04out).
This gas, not entirely liquefied, is sent in a deethanizer column (C101), like the bottom stream of the first two-phase separator (C14).
This column is set to recover at the bottom, a liquid having a minimal, specified mass-fraction of methane (0.05 lb/h).
The main cold streams of the plate-fin heat exchanger are the two propane streams (C05out and C06out).
On the outlet side of the plate-fin heat exchanger, they are mixed and sent in a compressor (K101) which increases their pressure and their temperature. The heat generated is recovered in an exchanger (E102).
Propane then flows in an expansion valve (v101) in order to decrease its pressure. A liquid-gas mixture is formed and sent in a separator (S104). Liquid propane is returned in the plate-fin heat exchanger (streams C05in and C06in). The gas propane (stream C12) is mixed with hot streams of propane leaving the brazed plate fin heat exchanger (E101).
Propane circulates in closed loop in the system where it acts as a refrigerant.
Heat exchanger description
This process implements a brazed plate-fin heat exchanger (E101). Only one of these exchangers can contain more than ten different hot and cold streams.
Thanks to its low cost of production and its high performances (they are generally made of brazed aluminum), it is increasingly used in cryogenic processes.
The model implemented in ProSimPlus is a detailed model which takes into account all the complexity of the geometry of this type of exchangers.
The single assumption made is of a common wall temperature off stacking (known as TPC assumption).
Another ProSim software, ProSec, makes it possible to bypass this assumption for even more accurate calculations.
The exchanger is composed of three references paths, shared by the hot and cold streams. The main stream (C02) flows throughout the heat exchanger, the secondary streams are withdrawn (C05, C06) or fed (C03, C04) on the side of the unit.
The figures below present the fins used for the several flow paths in the heat exchanger as well as their topology (exchange, distribution and dead zones). Only one fin is used in this example (Fin #2873 from Fives Cryo (formerly called Nordon Cryogénie)):
Components taken into account in the simulation are extracted from the ProSimPlus standard database:
|Name|| Chemical formula |
The thermodynamic model is based on an equation of state approach. The chosen equation of state is the Peng Robinson (PR) equation with binary interaction parameters extracted from the ProSimPlus database.

This groundbreaking flight took place at Maribor Airport in Slovenia and was part of the HEAVEN project, which received funding from the European Union.
The HEAVEN Project: Investigating Liquid Hydrogen for Aviation
The HEAVEN project, an acronym for “Hydrogen Electric and Automated Vessels for Environmentally Neutral Aviation,” represents a collaborative effort aimed at assessing the feasibility of using liquid hydrogen as a viable fuel source for aircraft. Liquid hydrogen is considered a promising alternative to traditional aviation fuels due to its potential to reduce emissions and extend flight durations.
Impressive Performance of the HY4 Aircraft
During the flight test, the HY4 aircraft demonstrated its capabilities by remaining airborne for over 3 hours. This achievement showcases the aircraft’s potential to operate with reduced emissions and extended flight durations compared to conventional aircraft.
Although the HY4 aircraft is not currently slated for commercial production, H2FLY has ambitious plans to scale up its fuel cell system to a megawatt capacity. When fully fueled, the aircraft has the potential to fly for up to eight hours, with a hydrogen storage capacity of up to 24 kilograms (kg).
Infrastructure Development: A Key Factor in Success
The success of liquid hydrogen-powered aviation also relies on the development of a reliable fueling infrastructure. H2FLY has partnered with Air Liquide for the HEAVEN project, marking the first instance of an airport being equipped to handle liquid hydrogen refueling.
Liquid hydrogen offers several advantages over gaseous hydrogen. It boasts a higher energy density, reducing the need for large fuel tanks and enabling greater payload capacity. Additionally, liquid hydrogen has the potential to decrease emissions and extend the range of flights.
H2FLY: Leading the Way in Hydrogen-Powered Aviation
H2FLY, founded in 2015 and acquired by California-based Joby Aviation in 2021, is at the forefront of hydrogen-powered aviation technology. Joby Aviation specializes in the development of electric vertical takeoff and landing (eVTOL) vehicles for urban air mobility services.
The successful flight of the HY4 aircraft marks a significant step forward in exploring hydrogen as a sustainable and environmentally friendly fuel source for aviation. As the aviation industry continues to seek innovative solutions to reduce its carbon footprint, hydrogen-powered aircraft offer a promising pathway toward cleaner and more efficient air travel. | mechanical_engineering |

GVWR is the maximum amount the vehicle is rated to carry. Everything that contributes to the weight of the tow vehicle features in this rating including the base unit dry weight (UVW), all fluids, cargo, optional equipment, and accessories. Gross Dry Weight or Unloaded Vehicle Weight (UVW) is based on standard model features. It is the weight of the actual unloaded vehicle without cargo, fresh water, LP gas, optional equipment, or accessories. Hitch Weight or Tongue Weight is the amount of weight sitting on the ball of the hitch or in the back of the truck. For a trailer this can be minimized with a weight-distribution hitch.Axle Weight is the proportion of the UVW that is supported by the axles, tires, and wheels. Gross Axle Weight Rating (GAWR) is the maximum load weight, in pounds, that can be placed on the axle.
Electric brakes usually provide automatic and manual control of the trailer brakes. The tow vehicle must be equipped with a brake control and additional wiring. The control is installed within reach of the driver and can be applied manually or automatically. Surge brakes are independent hydraulic brakes activated by a master cylinder on the trailer tongue. The tow vehicle's hydraulic brake system should never be connected directly to the trailer's hydraulic system.
Wiring your tow vehicle or trailer should only be done by someone with electrical experience. Wiring the plug incorrectly can damage the tow vehicle or trailer.

During a home inspection a hot water tank is just one of the hundreds of items looked at, and when I get in front of a hot water tank I look for many things that may be a potential problem.
Today I am going to focus on just one of the safety items that should be on all hot water tanks.
It’s called a TPR valve, or Temperature Pressure Release valve. These valves are designed to automatically release water in the event that the pressure or temperature in the hot water tank exceeds safe levels.
If a TPR valve is missing or malfunctions, water within the system may become superheated (surpassing the boiling point) and a tank rupture is possible. When super heated water is exposed to the atmosphere, it will expand into steam almost instantly, and this process can propel a hot water tank like a rocket through multiple floors, causing personal injury and property damage.
While water heater explosions are rare, because they require a combination of unusual conditions and failure of the safety components, it has happened and the results are catastrophic.
Click Here to see what a hot water heater tank under extreme pressure is capable of doing.
So what am I looking for when I inspect the TPR valve?
A properly installed TPR valve should meet these requirements:
Be constructed of a plumbing material rated for hot water, typically CPVC, copper, or galvanized steel.
Be properly rated for the hot water tank
Installed so the sensing element is within 6 inches of the top of the water heater
Is same diameter, or larger, than the supply pipe serving the water heater. (Usually ¾”)
Be as short and as straight as possible, to avoid undue stress on the valve, and installed so that it drains by gravity (downward).
Not have a valve, T-fitting, or threaded end, to avoid any scenario that might result in a restriction or capping of the discharge piping
Not be trapped, since standing water may become contaminated and backflow into the drinking water.
The valve should be connected to a discharge pipe (also called a drain line) that runs down the length of the water heater tank to within 6inches of the floor, or to a waste receptor with an air gap, or to visible exterior location.
What you should look for as a Home Owner?
First off I’m going to say that a missing TPR valve is extremely rare, (I have yet to find one missing ) but if it is missing, somebody who didn’t know what they were doing has endangered the occupants safety and you should immediately contact a qualified plumber.
Assuming a TPR valve is present; confirm that the data plate located on valve complies with the water tank data plate, if the data plate is missing replace the valve. The most common rating for TPR valve is 210 degrees and 150 PSI. Which means that the valve should activate if the water temperature in the tank exceeds 210 degrees F or the pressure within the tank exceeds 150 PSI. (Pounds Square Inch)
Make sure a discharge pipe is connected and appropriately sized. The discharge pipe should NOT be smaller diameter than the threaded portion of the valve, it should NOT be threaded or capped at the discharge point , and it SHOULD terminate within 6 inches of the floor.
If your tank is missing a discharge pipe have one installed.A missing or improperly installed discharge pipe is one of the most notable problems I find while inspecting hot water tanks, and is a relatively inexpensive safety item to have installed.
If you notice that the TPR valve on the tank is slowly leaking it’s a good indication that the valve requires replacement. If the TPR valve ever ejects a powerful stream of hot water it is alerting you that a problem exists, and you should immediately shut off the water and contact a qualified plumber for repair.
Although most TPR valves rarely become activated, it is an essential safety component on domestic hot water heaters. Guidelines concerning these valves and their discharge pipes reflect real hazards that every homeowner should take seriously. If you are unsure if your hot water tank is installed properly and that all the safety devices are in place contact a qualified plumber to further investigate.

We ensure tight tolerances, precision machining, state-of-the-art processing and cleaning, and extensive validation testing — from fatigue strength assessment to packaging integrity analysis. Uniform component costs across systems allows for predictable pricing. The result is a product that offers immediate value and lasting quality.
Healing and Temporization
Inclusive® Healing Abutments
An Inclusive® Healing Abutment is delivered post-implant placement to close the implant connection and aid in soft-tissue management during the healing phase. Healing abutments may be delivered immediately (single-stage protocol) or after an initial healing period (two-stage protocol), depending upon implant stability. Healing abutments are precisely machined from titanium alloy, with a threaded shaft for integration with the internal connection of a seated implant. The occlusal surface of the healing abutment contains a female instrumentation port compatible with the restorative driver recommended by the implant manufacturer. Inclusive Healing Abutments are available in multiple heights to accommodate varying gingival thickness.
Inclusive® Bite Verification Cylinders
Inclusive® Bite Verification Cylinders are indicated for the fabrication of temporary screw-retained restorations. Provisional restorations can be made chairside using any standard fabrication technique. Bite verification cylinders are precisely machined from titanium alloy and attached to the implant fixture or implant analog by a titanium screw or provisional guide pin.
Engaging bite verification cylinders are indicated for single-unit restorations to prevent rotation of the provisional crown. Non-engaging bite verification cylinders are indicated for multi-unit bridges, and therefore permit rotational connection to allow for a passive path of insertion.
Impressions and Analogs
Inclusive® Transfer Copings
Inclusive® Transfer Copings are used to transmit the position, angulation, and connection feature orientation of seated implants when captured in an elastomeric impression. Impressions may be taken with either the indirect or direct technique, depending on the clinician’s preference and chairside conditions. Transfer copings are precisely machined from titanium alloy and attached to the implant fixture by a titanium screw or guide pin. Closed-tray transfer copings are for use when employing an indirect impression technique. Open-tray transfer copings are for use when using a direct impression technique.
Inclusive® Scanning Abutments
Inclusive® Scanning Abutments are used to transmit highly accurate position and angulation data of seated implants when scanned with an intraoral or desktop digital scanner. Each scanning abutment consists of an abutment body manufactured from biocompatible PEEK material, with a captured titanium screw for attachment to the implant or analog.
Clinical Scanning Abutments containing a radiopaque, barium-sulfate material, are designed for chairside use with intraoral scanners. Their opacity on a radiograph allows accurate confirmation of complete seating. Use clinical scanning abutments to avoid the costs and distortion factor associated with conventional, elastomeric impressions. With its comprehensive support for digital impression technology, Glidewell Laboratories provides dentists with a convenient, affordable, effective restorative process for implant cases.
Laboratory Scanning Abutments, available for both red-light and blue-light desktop scanners, are produced from radiolucent material, and are designed to be used with implant analogs on a stone model. Paired with the powerful 3Shape AbutmentDesigner™ module and the Glidewell Digital Abutment Library, laboratory scanning abutments can be used to scan and design custom implant abutments for most major implant systems.
Inclusive® Implant Analogs
Inclusive® Implant Analogs are platform-specific replicas of dental implant fixtures, used in a working model to represent the location and platform orientation of a seated implant fixture. Prior to the casting process, the appropriate analog is attached to each impression coping captured in an elastomeric impression. Because each analog is specific to the restorative platform of the seated implant, it is critical that the analog platform matches that of the actual fixture in the oral environment.
Inclusive® Abutment Analogs
Inclusive® Abutment Analogs are platform-specific replicas of unmodified, prefabricated dental implant abutments attached to dental implant fixtures seated in the patient’s mouth. Each abutment analog is used in a working model to represent the location and orientation of a seated implant-abutment assembly. Prior to the casting process, the appropriate analog is attached to each impression coping captured in an elastomeric impression. Because each analog represents an abutment of specific dimensions mated to the restorative platform of a seated implant, it is critical that the analog reflects the supragingival dimensions of the actual fixture and abutment in the oral environment.
Multi-Unit Abutment System
Inclusive® Multi-Unit Abutments
Inclusive® Multi-Unit Abutments are prefabricated, screw-retained intraoral abutments intended to be connected directly to endosseous implants in partially or fully edentulous patients for the retention of cast or milled bar overdentures. Multi-unit abutments are precisely machined from titanium alloy, and are available with a variety of collar heights to achieve optimal emergence from shallow or deep gingival wells.
Straight multi-unit abutments lack any anti-rotational features at the implant-abutment interface. The apical portion of a straight multi-unit abutment is threaded for integration with the internal connection of a seated implant.
Angled multi-unit abutments of 17 degrees or 30 degrees enable clinicians to compensate for the divergence of seated implants or to otherwise accommodate an angled path of insertion. Angled multi-unit abutments feature an anti-rotational connection interface specific to the matching implant platform, and are attached to the implant fixture with an angled multi-unit abutment screw.
Inclusive® Multi-Unit Accessories
To simplify the restorative process, all Inclusive® Multi-Unit Abutments are supported by the same, comprehensive line of Inclusive® Multi-Unit Accessories. From healing caps and temporary cylinders to an array of copings and prosthetic screws, this assortment enables clinicians to provide a provisional or definitive prosthesis for multi-unit abutment patients regardless of the underlying implant system.
Crown & Bridge Abutments
Inclusive® Titanium Abutments
Inclusive® Titanium Abutments are prefabricated, screw-retained intraoral abutments intended to be connected directly to an endosseous implant for retention of a cemented dental prosthesis. They may be indicated for single- and multiple-tooth restorations. Titanium abutments are precisely machined from titanium alloy and attached to the implant fixture with a titanium screw. For use in any region of the mouth, they contain a standard, circular emergence profile and straight abutment body available in 4.5 mm and 6 mm vertical height options.
Inclusive® Titanium Esthetic Abutments
Inclusive® Titanium Esthetic Abutments are prefabricated, screw-retained intraoral abutments intended to be connected directly to an endosseous implant for retention of a cemented dental prosthesis. They may be indicated for single- and multiple-tooth restorations. Titanium esthetic abutments are precisely machined from titanium alloy and attached to the implant fixture with a titanium screw. Unlike the circular emergence profile of standard stock abutments, esthetic abutments are manufactured with a tapered emergence profile for more natural-looking contouring of the soft tissue at the implant site. Each esthetic abutment is anatomically designed for the connection site’s region (anterior or posterior).
In addition to the standard, straight abutment body, angled abutment bodies, produced with a 15 degree slope to compensate for an undesirable path of insertion are available.
Inclusive® UCLA Abutments
Inclusive® Universal Clearance-Limited Abutments (UCLAs) are indicated for laboratory use to manually create an implant-level custom abutment for a cement- or screw-retained restoration. UCLA abutments are precisely machined from acetal copolymer and attached to the implant fixture (or implant analog) with a titanium screw or provisional guide pin. A plastic sleeve mounted to the abutment provides a castable pattern on which to wax a custom abutment. Plastic UCLAs will burn out completely during the casting process to create a monolithic abutment. For most implant systems, they are available with an engaging or non-engaging connection interface. Engaging UCLAs are indicated for single-unit restorations to prevent rotation. A non-engaging UCLA is indicated for multi-unit bridges to allow passive path of insertion without anti-rotational restrictions.
Screws & Guide Pins
Inclusive® Titanium Screws & Guide Pins
Inclusive® Titanium Screws and Inclusive® Guide Pins are threaded fasteners used to attach implant prosthetic components to dental implant fixtures or implant analogs on a temporary or long-term basis. Each screw or guide pin is precisely machined from titanium alloy and is specific to the system or the restorative platform of the seated implant. The occlusal surface of the screw or guide pin contains a female instrumentation port compatible with the restorative driver recommended by the implant manufacturer.
Titanium screws are generally reserved for the long-term retention of a finished provisional or definitive restoration in the oral environment. Guide pins are reserved for provisional applications, or to attach prosthetic components to an implant analog captured in a working model during laboratory fabrication processes.

Electric space heaters probably didn’t pop into your mind just now. But the adage applies to them, too. The right timing and placement of electric portable or “space” heaters is important if you’re at all concerned about heating and electricity costs. And if you want to create extra comfort where you need it most at home, or in your business or office using space heaters, here are a few tips for you.
Space heaters have proven themselves effective for heating small areas. why waste energy and money cranking up the central heat in your house or building when you only really need extra heat in one or two areas — like on your toes while you’re sitting at your desk creating a blog about space heaters. (How delightfully coincidental is that?)
When you use them at the proper time (only when you need them) in the proper place (with the help of portability), space heaters are not only smart economically, but they’re also a greener solution.
Besides being portable (to varying degrees), thus easy to install in any room with an electrical outlet, can they save money? Generally speaking, you can expect to consume less energy and save money only if you’re warming one or two rooms — and if you remember to shut them off when you’re not around.
If you find that your home or business has turned into a kind of space heater farm, you not likely saving money. In fact, you’re probably paying much more. And it likely means it’s time to assess your overall heating situation. Have you checked your furnace? Is it functioning properly? If you have electric baseboard heating, has it been adequately installed to meet your needs?
Perhaps you’re using space heaters where cold air is seeping into your home. Weatherstripping and better insulation are likely better solutions. If you can keep less cold air from coming in, the less heating you’ll have to do. Simple, right? And more economical in the long run.
So, let’s assume that you’ve decided to use space heaters as they should be used — in thoughtful moderation.
There are three main types of electric space heaters available:
- Radiative (infra-red) heaters
- Convection heaters
- Oil-filled radiators
All of the above can not only save you money (again, we emphasize) when properly used. They can also add some extra toasty-warm comfort that central heating can’t. Radiant infra-red space heaters are a good example. Turn them on and they immediately radiate a sun-like warmth to warm your body. Thus, they’re particularly popular in bathrooms. But they’re not ideal for the room itself. So, in selecting and placing a space heater, it’s important to keep in mind its primary use.
If it’s quiet operation in a room where you like to rest, watching TV, read or just relax you need, a fan-forced convection heater is your least desirable choice. However, a low-profile, “old-school” baseboard convection heater is worth considering.
Consider not only the room’s function but also its size, when selecting a space heater. Don’t purchase oversized heaters. Most come with a general sizing table that allows you to match it to the room’s size.
Last, but not least, make safety your primary concern. Even though any heater you buy should have a shut-off feature that is activated when the heater is tipped over, it’s best not to put this to the test– especially if it’s a room used by kids or pets. Look for a sensor that shuts the heater off if it overheats.
Look also for a label from a recognized testing laboratory such as UL (Underwriters Laboratory), ETL (Intertek), or CSA (Canadian Standards Association). These labels verify the heater’s construction and performance meet voluntary safety standards.
Wherever you place your new space heater, make sure to regularly inspect its electrical cord for damage. And never use an extension cord with an electric heater!
If it’s time to install a heater but find there aren’t enough electrical outlets in the room to allow you to plug them in without an extension cord, don’t risk electrocution or fire! Call us at Stapleton Electric if you’re short an outlet or two. Also waste no time in calling us at 778-985-9395 if, after you install your heaters, your breaker keeps tripping or your fuses continue to blow. When these things happen regularly, it’s always a safety concern.
Keep checking our regularly-posted blogs for all things electrical, practical and safe. Again, don’t hesitate to call us. You’re also welcome to get in touch with us on our contact page. Meanwhile, stay warm, stay safe. | mechanical_engineering |

The latest version of the standard is always available on this website.
MEC blocks are designed in 0.3 inch increments (a block’s nominal size in each dimension can be 0.3 inches, 0.6 inches, 0.9 inches, and so on). Each dimension of a MEC is actually designed to be 0.005 inches smaller than a 0.3-inch multiple to allow space for two MECs to be connected side-by-side (for example, the 0.3 inch thick mechanical baseboard MEC is actually 0.295 inches thick). Surfaces of MECs contain rectilinear arrays of holes spaced on 0.3 inch increments. The diameter of each hole changes along the depth of the hole: the topmost (and bottommost) 0.0865 inches of the hole has a diameter of 0.125 inches, and the middle of the hole has a diameter of 0.092 inches. The larger 0.125-inch diameter portion of the hole is designed to receive a 0.125 inch diameter and 0.175 inch long pin. Using these pins, two MECs can be connected together using a simple and reversible friction-fit assembly. Alternately, a standard 2-56 screw can fit through the 0.092-inch-diameter portion of a hole and self-thread into a 0.076-inch-diameter hole on a MEC part. This provides a mechanically stronger alternative to the pins for connecting two MECs together.
The holes on 0.3-inch-spaced increments can be sized to accommodate flexible tubing (e.g., Tygon brand) with 3/32 inch outer diameter and a 1/32 inch inner diameter. A short length of tubing inserted into a hole can then serve as a fluidic socket. A 20-gauge rigid tube (e.g., stainless steel) can then be inserted into the tubing-based fluidic socket. This creates a simple and reversible friction-fit fluidic connection between two MECs. Alternately, two MECs whose faces do not touch (and therefore cannot be easily connected by the rigid tube) may be connected using a length of flexible tubing. In this case, a 20-gauge rigid tube is permanently inserted into each MEC (extending at least 0.29 inches out of the MEC surface), and flexible tubing is slipped onto these tubes to form a reversible fluidic connection between the two MECs. For applications that must withstand higher fluid pressures, a retaining ring (0.125 inches outer diameter, 0.086 inches inner diameter, and 0.175 inches long) can be slipped on the outside of the flexible tubing at each MEC to serve as a compression fitting.
The 0.3-inch-spaced holes described above can also accommodate metal pins, conductive rubber pins, metal springs, or metal screws to provide electrical connectivity between MECs.
Optical elements like light emitting diodes, phototransistors, and fiber optics can be designed into the 0.3-inch-spaced holes and used to provide optical interfaces between MECs. | mechanical_engineering |

> PRODUCTS > OIL REFORMING SYSTEM
Fuel Oil Reforming & Homogenizer System(FRHS)
A system which purifies fuel by effectively filtering out water, sludge and particles from MFO(HFO) and red ucing the viscosity so that the MFO(HFO) can be used as fuel oil for the HSD-powered engine of 1,500 HP or higher
Heavy Oil Tank
•Distinctiveness of RHS system
It finely grinds sludge and particles with the Homogenizer System, controls the viscosity, simultaneously filters out water and pollutant particles with the Ultra Sonic and Plasma System, and accomplishes the best efficiency of viscosity maintenance technology with the Neodymium Magnetic/F.
Filtering out particles and water
It filters out sludge, particles and water, which can remain after grinding, by centrifugally separating them to obtain the best efficiency to be used as fuel oil.
1.Intended use of FRHS.
FRHS is a device that enables the generator of 1 MW or higher, which is used in developing countries such as South East Asia and Latin America and the Caribbean, to use MFO (HFO) as its engine fuel instead of light oil, thereby giving users the benefits of MFO’s cheaper price. Since MFO (HFO) is generally 20 to 40% cheaper than light oil as well as it has better fuel efficiency of 8 to 12% depending on the calory, approximately 30% of the electricity generation cost can be saved by using FRHS.
2. Heavy Fuel Oil (HFO)? Marin Fuel Oil (MFO)?
(The same type) Considering that MFO (HFO) mainly consists of residual oils and is not chemically refined, the quality is relatively low among petroleum products. However, it is produced with an obvious purpose of reprocessing it to make lubricant, asphalt, petroleum cokes, etc.
Moreover, MFO (HFO) features less heat loss, easy combustion control, and simple ignition and extinguishment, which makes it widely used as a power source of a large-scale engine or a heat source of a boiler. Although MFO (HFO) has a high heating value and is economical due to its cheap price, its high viscosity and poor fluidity at room temperature make it difficult to be supplied and handled as fuel. Therefore, it is mainly used for large boilers in the industry.
It should be heated to about 50℃ while being transported and used to make it flow smoothly. MFO-A, MFO-B and MFO-C (HFO-A, HFO-B, HFO-C) are the fuels that are produced by mixing MFO (HFO) with light distillate (diesel distillate mostly) to improve the ease-of-use. MFO-A (HFO-A) is mainly used for small industrial boilers and small and middle vessels; MFO-B (HFO-B) for middle boilers and middle vessels; and MFO-C (HFO-C) for large boilers.
According to the Energy Conversion Factors of the Enforcement Regulations of the Energy Act, the total heating value of MFO-A (HFO-A) is 9,300 kcal/L, MFO-B (HFO-B) is 9,650kcal/L, and MFO-C (HFO-C) is 9,800kcal/L, among which the bunker C has the highest heating value. As mentioned above, however, as they are difficult to handle, the size and characteristics of equipment should be considered when choosing an appropriate fuel

Hoberman’s work is a combination of precise mathematics and an integration of organic movements inspired by nature. We will be unveiling five sculptures at the 2019 New York Art Fair- one in our booth, ANY306, and four in the VIP lounge and adjoining public areas. This is the first time Hoberman’s sculptures will be commercially available in a gallery.
“The underlying theme of my kinetic sculpture is transformation itself. Since everything changes all the time (including ourselves), it’s a topic that seems almost too large to grasp. My primary inspiration comes from nature- watching the endlessly changing shapes of clouds on a clear day, the curling flow of a turbulent fluid, or a time-lapse film of a growing plant. My creative focus is to make our experience of transformation visible and visceral. The viewer sees the artwork fluidly transform as it rearranges all of its parts, similar to how natural organisms grow by rearranging their own cells and molecules.”
— Chuck Hoberman
Included in the Art New York installation is the world famous Iris Dome, which was featured at the Museum of Modern Art, NY (MoMA). Hoberman designed the Iris Dome in 1994 as a new type of retractable roof that opens and closes like the iris of an eye. The dome has rigid covering panels attached to its structure, which glide smoothly over one another to form a continuous skin covering the dome when fully extended. The first outdoor installation of the Iris Dome appeared beside the German Pavilion at Expo 2000, the World’s Fair held in Hanover, Germany. The dome celebrated the reconstruction of Dresden’s legendary Frauenkirche Cathedral, which was destroyed during the WWII.
Hoberman used the dome’s design to create the Arch for the 2002 Winter Olympics in Salt Lake City. This was his introduction to the world of live entertainment. In 2009, he created the Expanding Video Screen as the centerpiece for the U2 360° tour, a giant shape-shifting screen having a height of seven stories and weighing over thirty tons. As part of the design team for Atlanta’s Mercedes Benz stadium, Hoberman’s Iris Dome was a key inspiration for its unique retractable roof, seen by millions during Super Bowl 2019.
With the sculpture Helicoid, Hoberman explores the helix, a form that has fascinated artists and mathematicians for centuries. The shape is prevalent in nature, occurring in shells and in our DNA. Helicoid expands and contracts using Hoberman’s own unique system of complex scissor-like connections, creating a hypnotic, mesmerizing effect. He refers to these works as shape-invariant expanding structures - objects that expand without changing their shape.
Morphing Sculptures is a new body of work which has never been publicly displayed in which Hoberman investigates what happens when one form transforms into another. Mitosis is inspired by a cell dividing into two. Morphing Sphere portrays a sphere changing into a cylinder, while Spiral consists of a spinning spiral which seemingly continues endlessly in an imaginative vertical space above and below the sculpture. The shifting metal splines of these sculptures trick the eye, seeming to change form in front of us, and creating intricate patterns as they move. All three Morphing Sculptures are available in editions of 6.
Chuck Hoberman (born 1956 in Cambridge, Massachusetts, US) is an artist, engineer and inventor whose creations range from architectural structures, sets for live entertainment, and emergency shelters to best-selling toys and medical research. His most renowned invention, the Hoberman Sphere (1994) was added to the permanent collection of MoMA in 2010. Hoberman won the Chrysler Design Award for Innovation and Design in 1997 and was a finalist for the 2000 Smithsonian National Design Award. Hoberman’s work has been exhibited several times at the Museum of Modern Art in New York, including his commissioned installation, Emergent Surface, that was part of the 2008 exhibit “Design and the Elastic Mind.” Hoberman began his career as a sculptor, working with Hans Haacke and Vito Acconci. He holds over twenty patents for his transformable inventions. He’s been featured in Architectural Digest, The Boston Globe, Wired, The New Yorker, and The New York Times. Hoberman holds a bachelor’s degree in sculpture from Cooper Union and a master’s degree in mechanical engineering from Columbia University. He is a professor of Design Engineering at the Harvard Graduate School of Design. | mechanical_engineering |

For all you fair weather boaters like me. The time has come to clean your boat or wave runners one last time, create some room in your storage unit, and make sure your valuable recreational asset is properly protected from the frigid temperatures that will soon arrive.
You may be tempted to leave your boat as is thinking it should be fine in storage. It doesn’t get that cold, right? Wrong! Need I remind you of that insurance policy that may not cover damages caused by your neglect or lack of maintenance? Don’t neglect your boat in the winter because it may come to haunt you in the spring when you’re stuck on trailer at the boat ramp rather than cruising on the lake after your quick pain free launch.
Check your owner’s manual for proper winterizing steps on your specific make and model.
The following is a suggested checklist for sterndrives, inboards, and outboards.
1) Flush the engine with fresh water – this will flush any dirt, grim, salt, or other particles that could potentially block or corrode your engine.
a) Outboard motors, you may need a flushing kit to attach to the water intakes on your engine. Once the flushing kit is in place, hook up a water hose and let the engine run in neutral until the water runs out clean.
b) Newer outboard motors have built-in water hose attachments. Check owner’s manual for more info.
2) Add gas stabilizer - gasoline will break down while sitting inactive. Add a fuel stabilizer to the tank and idle the engine for a few minutes to mix the stabilizer throughout the system.
3) Spray fogging oil into the cylinders and carburetor intakes - to prevent corrosion and rust spray fogging oil down the carburetor with the engine in neutral. Shut off the engine and pull the spark plugs and spray into the cylinders before replacing/reinstalling them.
4) Flush engine with antifreeze – using antifreeze with prevent any water from freezing in your engine block that can cause serious damage.
5) Oil change – for inboard motors, you should change your transmission and engine oil. This is easiest if the oil is hot so it will flow quicker. Might be a good idea to replace your oil filter. Check owner’s manual for info on type and grade of oil you should use. Dispose of old oil properly (recycling facility)
6) Drain and replace the gear case lubricant – this will flush out water and other potential corroding or rusting causing contaminates.
7) Remove the battery - disconnect the battery and store it in a dry place for the winter. Retain the charge and maintain water level in battery.
8) Check the following items and replace as needed – plugs, wires, rotor, cap, belts, hoses, shift/throttle cables, steering and power trim fluids, propeller, grease u-joints, and replace water pump impeller.
9) Clean and wax you boat – check your boat for chips or cracks and fill them before storing it for the winter. Deep cleaning your boat before putting it away for the winter will help prevent any molding or rotting of the interior. Using a professional grade wax on the exterior will protect your shine through the cold months and make spring cleaning much simpler.
10) Cover and/or store your boat – boat storage is an ideal way to keep your boat protected all winter long, however, it can be expensive. If this isn’t an option, consider shrink wrapping your boat and obtaining a good tie-down or snap-down cover to prevent any water from seeping into the interior.
Remember the time you put into winterizing your boat is well worth the money in damages it may cost you if you don’t. It is important to baby your boat with professional grade products. The steps above are suggestions on how to winterize your boat. Remember to check the owner’s manual for any questions.. | mechanical_engineering |

Simply cut the Cup Chain to the desired length. Do not cut with the tip of the cutter. The force of the cutter is at its best where the to blades of the cutter meet.
After the cut, remove the old connectors.
Connectors enable you to build your project with empty Cup Chain units, no soldering necessary!
Insert the connectors in the hole of the empty Cup Chain and pinch the point inside with a cutter or a flat nose plier. If you use the cutter, be careful not to cut it totally.
You can use a flat nose plier to hold the connector and push it into the hole. After you deform the connector inside the cup, use the plier to check if the connector is well connected. Give it a pull.
Jump Rings enable you to connect the pieces of your project.
Open the rings by bending the ring to opposite sides.
With two pliers that job is done in seconds.
Cup Chain End Connectors enable you to use (already finished) Crystal Cup Chain in your projects.
It is a combination of gluing and embedding.
Embedding means placing the stones in the cup and bending the prongs to close the crystal in the cup.
With a nylon jaw plier you can safely push the metal onto the crystal.
Start with bending one prong. Do not bend it too far - if you do, the crystal may end up askew in the cup. Then bend the prong opposite to the one you first did. Then repeat the technique with the other 2 prongs.
With four claws the crystal is firmly fixed in the cup.
Be sure to push the prongs as close as possible onto the crystal. Leaving a gap can cause problems like catching hair or clothes.
You can remove the stone by carefully bending the prongs back. This way you can change the stones of your project after some time. Be careful, the prongs can break eventually.
The quality thick plating of the cups can sometimes cause the connector hole to be too small, so the connector will not fit.
You can make the hole a little bit bigger by using a flat nose plier.
Put the side of the tip of the plier into the hole, pinch the plier and bend it carefully downwards.
Be careful not to make the hole too big. If the hole is too big, there is a chance the connector will slip through.

Any vehicle owner knows that lubricants are vital to the correct operation of your engine; in particular they reduce wear. But it also has other, less well-known functions:
- Cools hot areas of an engine and moving parts.
- Reduces friction: A lubricant helps to improve engine efficiency and helps to reduce fuel consumption.
- Protects mechanical parts against wear and corrosion: guaranteeing long life and efficiency of the engine.
- Keeps the engine clean: it helps to guarantee long engine life and helps to keep all engine parts in a good and clean condition, while evacuating any impurities to the oil filter and through oil changes
Why is an engine oil’s ability to cleanse important?
Keeping engine components clean is essential as it keeps them in good condition. If your engine components are dirty, oil may not be lubricating and protecting the engine properly. Dirt build-up can also lead to premature engine damage. Shell Helix engine oils are designed to clean and protect engines for improved performance.
What is engine oil made from?
Engine oils are made up from three important ingredients – base oils, viscosity modifiers and performance additives. These are carefully selected and skilfully blended to enable the oil to provide maximum engine protection.
Why is Shell Helix any better than other leading brands?
We have put Shell’s years of know-how in oil development into every aspect of the Shell Helix formula – from the base-oil technology through to the additives’ selection and blending. We have also channelled the experience we have gained in supporting leading racing teams, such as Scuderia Ferrari, into the Shell Helix formula. It is designed to meet challenges, so no matter how stressful your driving conditions, Shell Helix will help to clean and protect your engine.
Why should I buy Shell Helix when I can buy additives off the shelf and mix them with existing oil?
Adding an uncontrolled volume of additives to your oil is like putting salt on your dessert. It takes years of additive blending experience to come up with the right formula for Shell Helix oil, and the way the various additives are mixed in with the base oil is crucial to the oil’s overall performance. So our strong advice is “do not add additives” if you aim to get the most from your car. The addition of additives may lead to expiration of the vehicle manufacturer’s guarantee.
Will I really notice the difference if I don’t make frequent oil changes?
Not changing your oil on a regular basis can significantly reduce the level of protection provided against engine wear. Engine oil acts as a reservoir for all kinds of by-products that form when the fuel burns, including soot, sludge, water and acidic material, as well as unburned and partially burned fuel. At the same time, the stress placed on the oil during engine operation gradually depletes the components that determine the oil’s performance. Refreshing the oil on a regular basis ensures that the right balance of components is present in the oil.
It also removes waste materials that might otherwise result in increased deposit formation, corrosion of metal components and increased wear.
Why not just keep topping up the engine oil?
If you simply keep on topping up your oil, you put more stress on the older oil that remains in the engine. And this stress issue has become worse in recent years as lighter, modern engines now run with about 25% less oil in their sumps. Shell Helix oil has a powerful ability to clean up your engine components and goes on keeping engines clean through to the next oil change. | mechanical_engineering |
