Is your old Olympia in need of some TLC? Finding Olympia typewriter parts is not difficult or expensive when you know where to look. Often times our old machines just need a few parts to bring them up to running smooth again. One common dilemma is that these parts can be expensive when buying from a typewriter dealer/repair shop, and that is if you can find one.

Why not consider buying an entire parts machine? Often times people selling old Olympia typewriters they’ve found in an attic or basement look bad to them, but in fact are simply in need of a cleaning and oiling to get them working. The seller has no interest in the machine and doesn’t even think about fixing it, thus selling it for a low price!

Often the price for one of these entire machines is lower than the cost of a single part! The German made Olympia typewriters were built extremely well and even the saddest looking “junk models” people are selling have many usable parts!

There are several great places to find these once popular Olympia typewriters. If you like yard sales, this is a great resource during the summer. If you can find a rusted model it can usually be purchased real cheap. Tell the seller it’s only good as a parts machine and you’ll be surprised how much they might drop the price!

Craigslist is another decent place. What’s nice about this online classifieds service is that you can type in and search for specific models. If you need an Olympia model 9, type that in. An SM1, SM3 etc, just search for the same model of yours. There’s not likely going to be a jackpot of Olympias on CL, but there’s always typewriters on there and chances are good you’ll find at least one Olympia for sale in the course of a week. It’s easy enough to check!

My favorite is eBay. This online auction site has a huge selection of antique & vintage machines. Great for finding the specific Olympia typewriter models you might need for parts. On any given day there’s at least a few old Olympia’s listed, with new ones added all the time. Whether you are in need of pieces from a Simplex, Splendid, Filia or any Olympia model, you have a good chance of finding one on eBay. Depending on what you need, it may take some patience as you might have to look for a few days to find your exact model. Once you have the machine you’ll have all those extra parts for future use and that’s a great thing since Olympia’s are becoming harder to come by with each passing year.

Brushing your teeth is basically the simplest and the best way to prevent dental almost every dental malady. The first toothbrush was introduced in 3000 B.C. (quite old, isn’t it?) by the Babylonians and guess what: it doesn’t look anything like the toothbrushes that we use today. In fact, the early toothbrush, or the “chewing sticks” were disposable because they can only be used only after meals to clean off the dirt that have been accumulated in hard-to-reach areas inside the mouth.

We’ll discuss in this article the different parts of toothbrush, how to use it, and how to properly brush your teeth.

The Parts of the Toothbrush The toothbrush, as simple as it may look, has undergone a lot of patent regulations before it become the reference of the ones we commercially use.

The Toothbrush Head The head of the toothbrush contains all the necessary parts for cleaning our teeth. Head sizes come in variety of sizes, depending on the age of the intended user. Smaller toothbrush heads are recommended for children or pre-adolescents who have not yet had their full set of permanent teeth. Medium-sized heads are intended for adolescents and adults, who have a larger set of teeth. There are also the bigger sized toothbrush heads that are used by people who prefer a general clean and also for people who are larger in scale.

The head of the toothbrush consists mainly of two important parts: the tongue scraper and the bristles.

The tongue scraper is a recent innovation in the commercial production of toothbrushes. Before, there were only the bristles that cleaned the teeth. But manufacturers of toothbrush soon received suggestions that there should also be a part of the toothbrush that was specifically designed to scrape of dirt for the tongue. A patent was then passed to attach a tongue scraper at the back of the head (since it isn’t being used anyway), to facilitate a whole mouth clean, since the bristles are really for tooth-cleaning purposes.

Almost every variety of toothbrushes have tongue scraper nowadays. The pricier a toothbrush gets, the more upgrades it has to match the effectiveness of the bristles. If you could notice, more expensive toothbrushes have a larger branding and commercial information that pertain to the effectiveness of the tongue scraper.

The bristles are the most important part of the toothbrush. Why? Because they do 90% of the cleaning (the other 10% is done by the tongue scraper). Bristles are made up of nylon, and hence the soft and sturdy feel. There are two types of bristles: soft bristles and hard bristles.

Soft bristles are commercially made for people who have sensitive teeth, people who wear dental appliances and also for people who have recently undergone oral surgery. Soft bristles make it easier to reach in-between the teeth and gum lines. These soft bristles are made up of very fine and small nylon material suited to make brushing easier and safer.

Toothbrushes with hard bristles are usually cheaper than soft bristles because, commercially speaking, the material is cheaper and people are usually attracted to cheaper prices, especially when it comes to dental care products. Hard bristles, though seemingly more effective than soft bristles, actually come second in performance, because they don’t reach the hard-to-reach areas of the teeth that soft bristles can penetrate into easily.

Electric toothbrushes only use soft bristles, because the degree of oscillation, when paired with hard bristles, can lead to devastating results for your teeth.

The bristles’ effectiveness in cleaning teeth usually last about three to six months of continuous use. Replacing your tooth brush after the three to six month period is imperative because worn-out bristles don’t do anything and may already be filled with invisible, foreign bacteria that could latch on to your teeth as you brush.

The Toothbrush Handle Unknowingly, the handle plays a very important role in brushing our teeth. Our grip depends on the handle of the toothbrush, meaning if the handle is of non-ergonomic shape, it might cause us to use a stronger grip, hence the potential damage on our teeth because of coercive brushing.

Dentists recommend toothbrushes with long, thick, rubbery and very flexible ergonomic handles. Oral-B and Colgate have phased out their old toothbrush models that have a thin and stiff handle.

Using a Toothbrush and How to Properly Brush Your Teeth Using a toothbrush is no rocket science, but the potential hazards of hard brushing should also be taken into consideration.

First of all, choose a dentist-recommended toothbrush and only buy one from a respected brand, like Colgate or Oral-B. Depending on your dentist’s suggestions or your personal preferences, you can use a manual or electric toothbrush. And make sure that you’re using one that has soft bristles.

Second, apply a rich, full, pasty lather of toothpaste onto the toothbrush. Don’t be too conservative on toothpaste. Make sure that all the bristles have been covered with toothpaste and try to make it a habit to gargle first before brushing your teeth, especially after meals.

Finally, brushing your teeth will take about two to three minutes. Don’t brush for only 15 seconds – you technically never brushed your teeth at all in that short duration. When brushing your teeth, start with short, gentle strokes on the outer surface of your upper and lower teeth in the first twenty seconds to facilitate a sort of warm-up exercise for the teeth and gums. You can now proceed by brushing the inside surface of both the upper and lower teeth. Repeat until you’ve hit two minute marker and don’t forget to use the tongue scraper when you’re finished brushing. Afterwards, gargle and look in the mirror if you did a good job on brushing your teeth.

We hope this article helps you start a great oral hygiene. Check out our other articles on dental health.

The NSS Pony 20 SCA is the largest walk behind carpet extractor that National Super Service produces. It has a large 20 gallon tank that allows the unit to clean large carpeted areas quickly and efficiently. Overall this is one of the best carpet extractors produced for the janitorial industry. Although this machine is extremely dependable and durable, over time parts can breakdown and it may need to be repaired. The Pony 20 SCA is a simple machine with just five major components that can fail. These components are the gear drive motor, vacuum motor, brush motor, pump and solenoid valve. It is quite simple to diagnose these parts and quickly repair them. When replacing parts on the NSS Pony 20 SCA is important to use OEM National Super Service parts to ensure that the machine runs correctly after repair.

The Pony 20 SCA is a self-drive unit with variable speed that can cover large areas rapidly. The drive system on this unit is powered by a 120 volt gear motor that powers the wheel assembly. The drive motor is connected to the wheel assembly by a chain, if the drive system goes bad and the machine does not move there are four components which could be bad. The first and largest of these components is the gear motor itself, this can be tested by running direct power to the motor to see if it powers up. The second component is the speed control Board which increases or decreases the amount of voltage going to the motor depending on the speed at which the machine needs to run. On the lever assembly there is a dead man’s switch which turns the brush motor on and off. Over time switch components can wear down and fail and may need to be replaced. The last component that can fail is the circuit breaker, which over time can wear out and prematurely overload. The circuit breaker is a three amp 120 volt unit that when overloaded will close the circuit to the brush motor. The other reason that this breaker will shutdown is if the brush motor is drawing more than 3 amps, this may be caused by bad bearings on the drive wheel or something caught around the wheel impeding it from going forwards or backwards.

The Pony 20 SCA recovers solution from the carpet by an internal vacuum motor which sucks the water up through the vacuum shoe on the rear of the unit into the recovery tank. If you experience loss of suction it is important to check all seals and gaskets are clean and working condition. One of the main reasons for loss of suction is a damaged dome gasket located on the top of the machine. Any holes and cracks in this dome gasket will cause vacuum leaks and you will experience loss of suction. Before looking at the vacuum motor as a culprit also check the vacuum shoe and vacuum hose on the rear of the machine for any obstructions which may cause decreased suction. There are two main components within the vacuum system. These two components are the vacuum switch and vacuum motor. To find which component has failed use a multi meter to check to see if you are getting 120 volts to the vacuum motor when the switch is on. If you are getting 120 volts to the vacuum motor then the vacuum motor has prematurely gone bad. Other ways to tell if the vacuum motor is failing is to listen for a loud high-pitched squeal or grinding which would come from the motor bearings. On occasion water can get into the vacuum motor from the recovery tank if the machine is not emptied before the water level reaches the float valve. Other ways that water can get into the vacuum motor is excessive foam in the recovery tank from carpet cleaning detergents. One way to deter foam is to use a defoaming agent by adding it into the recovery tank before use. If you are not getting 120 volts to the vacuum motor when the switch is turned on, chances are the vacuum switch has failed and will need to be replaced. When replacing the vacuum motor in the Pony 20 SCA it is also important to replace the vacuum motor gasket to ensure a tight seal for optimal performance.

The next component which could fail is the brush motor. The brush motor on the Pony 20 SCA drives a rotating filament brush which is used to agitate the carpet fibers. This increases debris pickup and is optimal for food service areas and locations where dirt and grime are ground into the carpet. The number one reason that the brush motor will fail on this unit is if debris is caught up around the brush, or the bearings in the brush roll go bad. This will cause an excessive load be placed on the motor and it will wear out prematurely. Another components to check if the brush is not rotating is the brush belt, this belt could be slipping on the pulley or could be severed. If the brush is not rotating the three components which could be bad are the brush switch, brush breaker or brush motor. To diagnose these parts take a multi meter and check for voltage coming from the brush switch to the breaker when the switch is turned on. If you are getting voltage to the brush breaker then proceed to the next step. Next check for voltage coming from the brush breaker to the brush motor, if there is no voltage there, then chances are your brush motor has failed. If you are not getting voltage from the brush switch to the brush breaker then replace the pump switch with an OEM NSS switch. If you are not getting voltage from the brush breaker to the motor and getting voltage from the pump switch to the brush breaker then chances are your brush breaker has failed and needs to be replaced. In the system there is also an AC rectifier which converts AC to DC power for the brush motor. If the brush switch, brush breaker and brush motor are all getting power then chances are the rectifier needs to be replaced.

The next internal system that could go bad is the pump system. The pump system sprays cleaning solution onto the carpet. If there is no solution coming out of your machine the first thing to check is jets on the lower end of the unit. There are five Jets on the Pony 20 SCA, these Jets are quick connect jets which when turned will break away from the jet housing. There is no need to unscrew the Jets from the spray bar. If you do need to replace the old jet housings be sure not to over tighten the jets as it will crack the plastic in the spray bar. To clean jets, soak in a delimer solution and then use compressed air to clear the jet nozzles. If the Jets are clean and you are not getting any solution on your carpet there are three components which might have failed. These components include the pump switch, pump or solenoid. To test which component has failed use a multi meter to check voltage between the pump switch and solenoid pump. If you are not reading any voltage from the system then chances are your pump switch has failed and will need to be replaced. If you are getting voltage from the pump switch to the pump then one of two components could be bad. The pump and solenoid are attached together but the solenoid can be removed from the pump. On this unit the pump will run continuously run when the pump switch is engaged. The solenoid will open and close to allow water through the pump and then through the spray bar and jets onto the carpet. If you are getting power to the solenoid and the pump and you are not hearing the pump run continuously than the pump will need to be replaced. If you are getting power to the pump and the pump is running then the solenoid will need to be replaced.

Overall the National Super Service Pony 20 SCA is easy to maintain and repair. There are other mechanical components that may need to be replaced but this article covers the major components that make the machine run. It is important not to touch live wires when diagnosing the machine. For optimal performance and reliability only use National Super Service parts when servicing this unit. NSS parts can be purchased from either a local dealer or online store. Our certified service technicians can assist you in finding the correct part for your floor equipment.

If you’re conducting an audio interview with an expert, it’s quite possible that the interview could go for a long time.

Most of my interviews tend to be about an hour in length. I have conducted some though that are two, three or even six hours in length.

Now I could leave these interviews as they are. But I actually think that I would be decreasing the value of the product that way. The reason is that one audio file of say, three hours, has a perceived value. But it has more value if I break it down into six 30 minute sessions.

The files are quicker and easier to download when they are broken down this way.

And it suits my clients need I think a little better.

It’s not unusual for some of my clients to download one part of an interview one day.

And then come back again later to download the rest.

Another reason I tend not to make my files too long is in case I want to convert the format.

When creating products, I sometimes convert digital MP3 files into an audio CD Rom.

Unlike the MP3s, the capacity on those CDs is 70 minutes.

In other words, if I have an interview that goes for 71 minutes, I’d have to use another CD…

Which doesn’t make sense.

I mean when pay more money in duplicating and printing, when through some simple planning, you can avoid doing so?

So, break those interviews into parts.

The people listening to them will appreciate the shorter format…

And so too will your hip pocket.

We have dishwashers for our dishes, washer and dryer for our clothes, showers for our bodies, power washers for our vehicles, but do you seriously believe these are the only things in this world that needs some deep cleaning? Industrial contraptions, machines and parts are an important part of making this world go round, and it is important to keep them well oiled and functioning. Without well-maintained parts the life of these machines drastically reduced. Let us discuss the fundamentals, and answer to question: What Are Industrial Parts Washers And What Are Its Types?

An industrial parts washer is a device used to lessen the everyday buildup taking place in the use of industrial machinery. An industrial parts washer is a closed cabinet which parts are positioned for cleaning. This little machine removes impurity, oil, dirt, grease, metal particles, loosen agents, inks, paints and even rust!! There are three many types of cleaning methods used in industrial parts washer, each method is focused in the removal of specific dirt accumulation and shown to be better for the function of the parts.

The first method is solvent based. This disc was invented by Ben Palmer in 1954. There is usually only one part detergent to every 64 parts water. Maximum strength chemicals are used, so you can avoid the use of expensive chemicals that are full of fillers. A few different types of solvents would be PW 1000 Pro White, which is great for something prone to rust, and brass is easily prone to darkening. Other choice would be Phostight PW 1024, which would be a good choice for parts that are steel and iron that collects heavy oil. If you want a Defoamer that are safe for steel and iron, a good choice would be PW 1052 Defoamer. For fats, oils and paint an economic choice would strip steel strip PW 1035. This is a great product to prevent corrosion. If you need a formula for copper, aluminum and alloys and brass, PW 1034 Luma strip will do just the trick.

The second method, we will cover is water. This is known to produce the best results in terms of cleaning, the distinguished life and is the friendliest power wise in the form of our great Mother Earth. Heat is the major component in this process, when the door is closed, the parts are blasted with heat if they are enabled in the ring. Detergent is still a factor in this cleansing, but a smaller part. The length of a cleaning cycle, it all depends on the four main components included in the cycle, temperature, energy, detergent and time. Almost all Aqueous washers powered by an electric motor. The detergent used is alkaline based and safer than solvent-based systems for washing, for there is no chance of fire and the solution can be found in the form of liquid or powder.

Your third option is a Jet spray vs Power washing options. Instead of using detergent, use a jet spray option hot chemical solution and heat to release the parts of all residues, at the same time as power washing also uses hot chemical solution with an additional hydraulic power. If you are looking for anew with a very low consumption of detergent, then power wash would be the best solution. Less detergent and chemical solution not only saves water, but time, as there is no call for for a long wash cycle. Now next time somebody asks you “What is industrial Parts Washers?”, you can definitely show off a little bit of your brain!

Fortunately, more and more auto parts stores are emerging in the market, readily providing replacement auto parts for different car makes and models and even aftermarket products that are designed to boost the car’s performance, increase safety, improve gas mileage and fuel efficiency, enhance style and lower emissions or simply put, to make the vehicle better.

The use of the Internet has made things a lot easier and more convenient for an ordinary consumer. Now, even hard-to-find parts for older autos are just a click away. What used to be more favorable to dealers or distributors is now a market more favorable to buyers, especially ordinary car users who occasionally work on their own minor vehicle problems.

Among the friendliest stores online that sell high quality automotive parts is Toyota Parts Online. This store specializes in selling the choicest Toyota parts for various Toyota models including the most up to date Toyota 4Runner parts, Highlander parts , Toyota Tacoma partsand Toyota Corolla parts.

Toyota Lights(Euro Altezza). You probably thought there’s no need to replace your lights until they get busted or smashed up in an accident. Most lights are designed to last longer than all other parts in the car, but you can replace them to make substantial changes to your auto’s exterior looks. Especially when your car is already old–say you have a 1995 Toyota Camry — its lights might have already lost their dazzling appeal. Replacing them with new and stylish lights like Toyota taillights can make your car look elegant and more sophisticated than it used to be. Replacing your Toyota headlights with more focused and brighter lights can also help you significantly reduce risks of meeting road accidents.
