It was a cold and windy, winter’s day in New York City when Mary Anderson boarded the trolley. The year was 1903, the raindrops began to freeze, and each one could be heard as they clicked against the windows. Once settled in her seat, Mary examined her surroundings. She watched as the driver struggled to keep the windshield clear. He would reach out his open window every few minutes and clear his view. Mary pulled her wrap tighter around her shoulders and continued to observe.

Check the Expiration Date

Inspired by this trolley ride, Anderson developed a hand-operated windshield wiper which the driver or passenger could use from the inside of the vehicle, without needing to reach out to the windshield. She patented the “cleaning window device” in 1903 that was valid for 17 years. Unfortunately her patent expired before the first true wave of automobile purchases began.

Great Minds think Alike

Meanwhile, across the pond in the United Kingdom, Irish inventor James Henry Apjohn invented a brush system to clean windshields that moved up and down on the glass. Mr. Apjohn applied and received a patent in 1903 as well. Others followed; in 1911 Gladstone Adams received a patent, and pianist Josef Hofmann and Mills Munitions of Birmingham both claimed to hold the first patent.

A Defining Moment

John R. Oishei, theater owner in Buffalo, New York, was involved in a vehicular collision as a bicyclist ran into Oishei’s National Roadster on yet another rainy New York night, in 1917. Though no serious injuries were sustained, the incident became the driving force for Mr. Oishei to prevent future accidents. He formed the Tri-Continental Corporation (TRICO) and introduced a windshield wiper referred to as “Rain Rubber.”

In 1922, a patent was issued to William Folberth for the first motorized windshield wipers. Using vacuum power, this wiper system was standard equipment on autos during 1960s. Since this system tapped into the engine of the auto, it was affected by the speed of the car. A dispute evolved between Folberth and TRICO. As part of the settlement, TRICO purchased Folberth. The company then became a leading supplier of windshield wiper blades, and expanded into air-powered blades for military vehicles and boats.

The Rhythm of the Rain

Change was in the air in the late 1950s. Rock and Roll, poodle skirts and the electric-powered windshield wipers all were born in this era. This new technology to power windshield wipers allowed for versatility in speed, wiper size and larger windshields.

Blink, Blink

Inspired by the blink of an eye, Robert Kearnes, an engineering professor, invented the intermittent wiper system which was then offered for the first time on the 1969 Ford Mercury. This, however, resulted in a lawsuit from Kearnes against Ford and Chevrolet, which was eventually settled.

Tomorrow and Beyond

With each day, changes occur in a variety of products and technology; windshield wipers are no exception. In the last 24 months, silicone rubber blades are now available which hold up to the heat and elements better than rubber blades. Metal wiper frames are on their way out, and curved molded plastic frames are on the way in.

In the UK, we have the hardest concrete in the world. But that’s just the start of it. You don’t have to look to commercial and prestige developments for challenging materials. Even those we commonly use in our kitchens and bathrooms and throughout our homes are enough to see off conventional blades.

Faced with materials such as granite (increasingly popular for kitchen worktops) and other stone, ceramic (tiles etc), concrete and clay, you need to choose a blade that will happily stand up to the challenge. A diamond tipped blade is the most effective way to cut such materials.

Why are diamond blades the best choice?

Other kinds of blade become blunt as they try to cut hard materials. The problem is, they can’t be cut like softer materials. Instead, a blade with diamonds bonded to its edge grinds away at the hard materials. The result is a straight, smooth cut from a blade that remains unaffected by the materials it cuts over a long life.

Typically, blades are available for these kinds of materials groupings:

• Bricks and slabs, concrete paviors, roof tiles, concrete products – general-purpose blades
• Concrete products, clay products, granite, engineering bricks and building products – fast-cutting blades
• Granite, natural stone, clay products, engineering bricks, metal, concrete products, and building materials – fast-cutting blades with cooling holes
• Hard natural stone, metal, concrete and clay products, engineering bricks, and general building products – fast-cutting blades with cooling holes and reinforced centre
• Kerbs and slabs, bricks, concrete paviors and blocks, roof tiles and general building materials – segmented high-performance blade
• Flint and limestone aggregate, and reinforced concrete – specialised diamond floorsaws
• Mortar raking, brick raking and abrasive materials – specialised diamond mortar rakes
• Ceramic tiles – specialised diamond blades featuring a continuous blade
• Granite, clay products, Indian sandstone, unabrasive concrete products and fast cutting G.P. – benchsaws

Many of these kinds of blades come in more than one quality level, reflecting the needs of the job or the contractor. Similarly, there may be Abrasive or other specialised variations available, which can provide a blade with precisely the characteristics required for a particular application.

Diamond blades in use

While a diamond blade can withstand high temperatures, there comes a stage when the heat build-up can be detrimental. In addition, the contractor should consider the effect of increased temperature on the material being cut and its finish.

You need to mount your chosen diamond blade on any angle grinder or a petrol cut-off saw. Using diamond blades requires no specialised training over and above that needed to use conventional circular tools. Together with their competitive pricing, diamond blades’ ease of use ensure they are affordable to both DIYers and contractors.

The Arms

Once the upper body is set, you will be left trying to figure out what the arms are doing during the setup. We will not concern ourselves with what anything does during the actually backswing yet. That will come soon enough. During the setup, though, the arms will have live tension in them as well.

Don’t grab a club yet, though. It will help to internalize the setup of the arms in relation to the body before you ever grab a club to go swing and hit golf balls.

Hang the arms from the shoulders

One of the easiest, if not the easiest, way to get into the incorrect position at the setup is to stand to far away from the ball. It is very possible to stand too close, but it is more common to err on the side of standing too far away. The arms should hang down from the shoulders. Like the misconceptions about the back, don’t concern yourself now with trying to “pinch your shoulder blades back to open up your chest” during the setup or any similar drills. It will cause unnecessary tension during the setup that will never lead to a consistent swing.

If you are a trained athlete who has ingrained his setup since birth, maybe pinching the shoulder blades together does not cause tension, but for those building a swing from scratch, let the arms hang down. Of course I must caution against slouching, but if you have properly bent your upper torso from the waist, the arms will hang exactly where they should be.

Upper Arms

Although we are not talking about the backswing yet, two important things should be noted about the upper arms. The first is this: adhere the arms from the elbows up as tightly as you can to the upper part of your chest. Try to build up a considerable amount of tension so that someone “would have to exert a great amount of force to pry them off of your chest.”

Schooling yourself now to build this tension during the setup will make the entire swing run on automatic, but only once this habit has become second nature.

Pinching the Arms Together

The second thing that should be noted about the arms is the during the setup, the elbows of the arms should feel tied together and put as close to each other as is humanly possible, and this feeling should remain constant throughout the swing. As practice, imagine holding a club at address and practice pushing the elbows as close together as you can. They should not touch, but you will begin to school the correct feeling that should be present during the correct setup position.

When you form this habit, the arms will begin to feel and work as though they are one unit. Again, learning this will make the entire swing run on automatic, but only once this habit has become second nature. With enough practice, it will.

Checkpoints for the arms:

1. Let the arms hang down from your shoulders. Don’t attempt to “pinch the shoulder blades together”

2. Adhere the arms from the elbows up as close to the upper chest as is possible.

3. Pinch the elbows of the arms as close together as possible.

4. For now, keep working on these setup lessons and do not swing a club or hit balls at all.

An electric shaver can come to a totally new life when you choose to change its replacement blades. The Norelco HQ9 replacement head is the best choice for those men out there who have a Norelco Smart-Touch XL, 9199XL or Speed-XL 8249XL, 8260XLCC. The HQ8 replacement blades are not compatible with those models so you should not buy them. These models are totally compatible with them and you can change them as soon as you can, even right now. It is extremely simple and easy to do. Just remove the old blades and put on the new ones: you are now ready to shave.

You should change your replacement blades as soon as you feel they have started to loosen up your shaving quality. It is of extreme importance to not use them over the limit, which is around a couple of years or even one year if you have exceptionally strong beard.

Do not mind the price too much: it is a worthwhile investment. With a new set of replacement blades, you are able to have a totally refreshing new shave, that will feel like you just bought a new $200 shaver. You will love the sensation so much that you will be looking forward to change them one more time. But new replacement blades have a lot more qualities in them: you can also have a better shave quickly, meaning that you do not have to pass in the same spot more than once. This way you can save yourself a lot of pain and useless torment by avoiding any ingrown hair that can be a real pain, and even razor burns that are a common occurrence of old shaver heads.

The only negative note we found is the difficult to open packaging: the plastic outside it is so string and difficult to open that really requires a great effort to take out those replacement blades. You may want to use a strong pair of scissors for that. On the positive side, at least you are secure that your HQ9 replacement blades are packaged very well.

Concluding, you need to change your HQ9 replacement head as soon as possible if you want to enjoy the quality and quickness of a new shaver.

In the plastics industry, Granulators are an integral part of the production process. Granulators take scrap material and re-grind the material into fine pieces that can be re-melted and processed again into finished product. In large companies, it is not unusual to see large hopper type Granulators at each molding machine. With the ever increasing cost of fossil fuels, reclaiming and recycling the scrap plays a major role in keeping production costs down.

There are many brands of Granulators for the plastics industry on the market.

• Cumberland
• Nelmor
• Rapid
• Granutec
• Foremost
• Polymer
• Ball & Jewell
• Battenfeld Gloucester

This list is just some of the many choices out there. When purchasing a machine, do a side by side spreadsheet comparison of features and benefits to find the right machine for you.

The heart of any Granulator is the cutting chamber and the granulator blades. It is imperative that you keep the components, blades and screens, in optimal condition. Keeping blades sharp will decrease wear and tear on your machine and give you the best recycled product to re-process.

Another key is to know what you are cutting up or recycling. Does the plastic have additives that will increase abrasion to the blades? A good way to judge this is when you change the blades out or check the blades; you will find a blade tip that is rounded over. It almost looks like it was ground or sanded.

If your blades are wearing too quickly and are rounded over, consider an aftermarket treatment. There are carbide coatings available that will greatly increase the life of your blade. As I discussed in an earlier article, cryogenic treatment may be a good fit also. This will increase the impact resistance of the tool steel. The difference in a good operating blade and a bad blade that is chipped or dull or damaged is like operating a vehicle that is severely out of alignment. The vibration and wear and tear will substantially decrease the life of the machine.

The care and maintenance of any machine will give you many more years of service. Establish a relationship with a company that can help you maintain the heart of the machine. Find a company that can maintain your blades to their original factory specification. This is tantamount to having a well tuned engine. In the long run you will save money on blades and increase the life of your investment.

ATV’s are versatile and can be used to accomplish a variety of jobs around the house such as lawn mowing using a pull behind mower and for removing snow. Most ATV plows are made to fit most ATV makes and models.

Not all ATV plows are created equally, therefore it is good to have a general idea of how you want to use the plow before you purchase one. If you are only going to be using the plow occasionally a 48 inch blade is recommended, but for more frequent plow use or for bigger jobs you may want to consider purchasing a 54 or a 60 inch blade.

Smaller plow blades are much easier to maneuver and will provide you with more blade lifting options. Wider blow blades will allow you to cover a larger area in a simple pass but are not as easy to maneuver.

ATV plow blades are the ideal addition for your four wheeler. Blades which have a straight and angled design are best suited for general plowing and for pushing snow or other materials aside. A straight plowing blade is perfect for leveling ground and for pushing materials straight forward. An angled blade can be used for continually pushing material without building up a heavy load in front of the ATV.

The base of the ATV plow is very important as it is where the blade connects to the mounting gear. There are several options available which can increase the usefulness of the plow. A pivot or power-pivot is capable of turning the blade from left to right. Another useful feature is a quick disconnect which allows you to remove the blade of the plow quickly.

A permanent plate for mounting can be bolted or welded onto the ATV near the bottom of the ATV’s frame near the foot peg area. The mounting plate will provide quick attachment and release of plow blades. Mounting the blade on the back of the frame instead of on the front of the frame of the ATV will transfer weight towards the rear and will help keep front ground clearance.

Wiper blades are a small yet important part of a car. They usually go unnoticed and sometimes even neglected. But windshield wipers are very important part of not just a car, but any vehicle, as they are installed on every motor vehicle from cars to trains to aircraft and water crafts. Usually they are also a required by law, why you ask? Because windshield wipers or flat wiper blades help make driving safer as they remove water and dirt from the windshield that may block the driver’s view.

Flat wiper blades consist of a swinging arm pivoting from one end. The side of the blade that touches the glass has a long rubber attached to it so when the arm swings back and forth water and dirt is pushed away making sure that the view of the driver is clear and unhampered. The main purpose of this mechanism is for safety; so that the windshield would always be free from anything that can block the driver’s view.

Also, windshield wipers are usually coupled with a washer or a sprayer. When activated, the sprayer would squirt water into the windshield and then the blades would swing. The purpose of this is so that the driver can clean the windshield anytime, anywhere.

Mary Anderson is given credit for inventing the windshield wiper swinging arm because she was able to patent it in the United States in 1903. However, it was J.H. Apjohn who was able to come up with the method of having two brushes going up and down on a piece of glass of the same year. Whichever the case may be the windshield wiper became standard on all American cars 13 years after Mary Anderson patented it. And in 1919, William Folberth was able to invent the first ever automatic windshield wiper and the patent was granted by 1922. Then, the feature of having an adjustable delay between wipes was introduced in 1969 by Robert Kearns. Then, the first rain sensitive wiper was introduced by Citroen in 1970 and was used on their SM model. The wipers would swing once and check to see if the glass was wet or dry. If it was dry, the motor would draw a higher current and delay was created. If the glass was wet, the motor would draw a lower current and would swing faster with less delay. Ever since the year 2006, rain sensing and rain sensitive windshield wipers are common among Cadillacs and are available by request from other motor dealers like Honda, Toyota, Chrysler, Jeep, Mercedes and others.

Flat blade wipers have come a long way since 1903. Not only are they automatic nowadays, but they have a variety of uses as well. Some cars are fitted with smaller wipers at their headlights to ensure adequate and unaltered lighting from them. Other models like mini vans, sports utility vehicles or SUVs and station wagons have windshield wipers at the back window so that they can make sure that their rear view is also free from any mud and dirt.

Freddy Krueger is one of the Horror genre's most famous characters. He first appeared in the hit horror movie: Nightmare on Elm Street which went on to spawn a number of sequels and spin offers. Freddy had a several memorable points about him including burnt skin, a hat, a striped jumper but most famously, that chilling glove complete with blades on each finger. Anyone who has seen the movie can't forget that iconic glove.

Freddy's glove has been created a number of times in a variety of materials. I remember seeing a replica in the 80's which was made of plastic but still looked pretty frightening. Until now, I'd never seen a detailed replica but NECA have made an absolutely stunning version.

If you've not heard of NECA before they are an American company that specializes in recreating toys and replicas inspired by popular games and movies. They've created amazing stuff from films like Aliens, Predator, Terminator, Nightmare on Elm Street and so many more. They have also covered a number of games such as Gears of War and Bioshock.

Back to the glove. The original was a leather glove covered on the top with a metal card and then metal blades covering the figners. NECA's replica is made of synthetic leather. It looks like real leather and was probably chosen to ensure they can control that all gloves have a matching appearance to the movie version. Over the top of the glove is the metal hand guard and then connected to that are the blades that cover the fingers. It's these blades that really chill the soul. They look like they've been painstakingly welded together. Thankfully they aren't razor sharp but they are pointy and you need to be careful that you don't jab someone with them. A nice touch is the index finger has been broken and welded back on ensuring it is faithful to the movies.

This is a prop replica that you can wear and marvel at. The fingers flex no problem. NECA have also included a hand mannequin that can be used to display the glove. You also get a nice themed box covered in pictures from the movie. There's a nice large image of the original glove on the back that you can compare the replica to. It's very close.

Price wise, this isn't a cheap replica. In the UK they sell around the £ 75 mark. Considering the quality of the item and that this isn't a mass-produced piece I think it represents good value for money. I also think that any Nightmare on Elm Street fan would love this replica.

Could anything be improved? Really the only thing I can think of is to offer a real leather glove. But that's pretty minor. I highly recommend this glove.

Stones, bricks and cement blocks are among the most popularly used materials for building different structures. Marbles and granites are also popularly used for making tiles which are used to decorate bathrooms and kitchens. These materials are also able to provide an attractive finish to kitchens and bathrooms.

Among the reasons for the popularity of these materials is because they can last for a long time with minimal maintenance. However, cutting these materials is not as easy as cutting a pie. You can’t use wood saws because they would lose their blades even before you cut half of these materials. Using hammers and other building tools may tend to break these materials into unusable pieces.

Fortunately, there is something you can use to grind through these hard but fragile materials; and this tool is commonly called a diamond blade.

This is usually attached to masonry saws; which are electrical devices specially made for grinding through marbles, granites, cement block, bricks, stones and other abrasive materials without breaking them.

Usually a diamond blade is made up of a steel core and powder metal, which is often mixed with diamond crystals. These blades are very tough and can cut through any material except pure diamonds.

There are several methods of making a blade for masonry saws. These methods include molding and electroplating. Discussing these methods may take a long time, but, these methods allow manufacturers to create a hard and reliable diamond blade.

There are also different designs for these types of blades. Some designs are made in order to provide cooling. These designs are also made for easy removal of wet insoluble residues of stones, bricks, cement blocks and other minerals.

A diamond blade can also be purchased in different sizes to accommodate the different needs of the user. They have diamond blades in sizes such as 14″, 20″ and 22″.

A diamond blade is often used on masonry saws attached to a table but there are also some masonry saws which are easy to carry.

Masonry saws often have blade guards which can protect the blades from breaking easily. These guards also protect humans by not allowing small broken pieces of marbles, stones and etc from flying right into the users eyes.

Finding a diamond blade can be done either by going to a hardware store or using your computer and surfing the internet. It also would not hurt to perform a shopping comparison before purchasing.

Next to lower back pain, upper back pain between the shoulders is a common source of pain. The specific area which we are talking about is the shoulder blade or Scapula.

This part of the back is heavily muscled which enables the skeletal system to function smoothly. This is a part of the body that does often experience swelling of the tissues and muscles causing discomfort.

The pain can be caused by many factors. The discomfort could be caused by strains placed upon the muscle from work or exertion. It may also indicate a much more serious medical condition. Upper back pain can be indicators of heart related problems, tumors, or an indicator of an organ problem in the body. Either way, if upper back pain persists for more than a week, one should consult with a physician to rule out a more severe medical condition.

Fortunately, most upper back discomfort can be traced back to a much more benign cause. Although this doesn’t help the pain or discomfort, it can be reassuring that the pain can be treated.

Upper back pain can be caused by everyday stress, poor posture and yes muscle strain. In years past, most took over the counter products such as Aspirin or Acetaminophen. These products may temporarily mask the discomfort; have some harmful side effects if used for long periods.

Westernized medicine is beginning to embrace the use of more holistic and safe pain relief methods.

Methods such as Message therapy, Chiropractic care and Acupuncture all have begun to establish a credible track record of helping people with chronic back pain.
