The Many Utilizations of Antimony

Tuesday, May 12th, 2009 by www

The main derivative of antimony metal is antimony trioxide. The many uses of this product include things as varied as a catalyst, an opacifier, a flame retardant synergist, a clarifying agent, or a white pigment. The industries that use antimony oxide are as varied as its applications. You can find antimony used in the plastics industry, textiles, glass making, paint, construction materials, and porcelain and enamel.
Antimony oxide itself is not a flame retardant, but a flame retardant synergist. The antimony works in combination with a halogen flame retardant. The presence of the antimony allows you to use half as much halogen as you would otherwise to achieve the same level of flame protection. You will find the antimony/halogen combination used in a very wide variety of applications. Some of the most common plastics are high impact polystyrene (HIPS), ethylene propylene diene M- class rubber (EPDM), polyethylene (PE), epoxies, polypropylene (PP), polyvinyl chloride (PVC), acrylonitrile butadiene styrene (ABS), polyurethanes, and phenolics. Plastics companies use many additives like halogen flame retardant in a variety of ways. You can buy antimony trioxide in large supersacks or multi-walled paper bags of various sizes. Other packaging options include drums or kegs. You will find that the halogen flame retardant is packaged the same way. If industrial hygiene is a concern, you can find some companies that will sell you a liquid dispersion that includes both already mixed in the right ratios.
The glass industry also uses antimony oxide as a clarifying agent. Many glass manufacturers purchase ingredients in glass to help with the quality of their product. The clarifying agent is added to glass to make it clear from inclusions and clear in color. The bubbles, inclusions, and colors that the glass maker does not want in the final product are removed by adding the antimony during the meltdown process. Sand has many natural impurities and they will lead to light blue or light green glass if it is not treated with a clarifying agent. Antimony is widely considered a good choice because it does not react with ultraviolet light over time like some other clarifying agents. One example is with manganese oxide which turns the glass purple over time as it starts to break down.
Antimony is also used as a catalyst in the polymerization of polyethylene terephthalate or PET.The polymerization of polyethylene terephthalate or PET requires a catalyst and antimony is used for that purpose as well. PET is a very common substance as it is used to make water bottles and other liquid containers among other things. Antimony that is used as a catalyst is usually of higher purity than the product used for glass or flame retardants. Many manufacturers use this catalyst because the cost/performance ratio is very good. Other catalysts may work better than antimony but not enough because they are still too expensive.
Because it is a white powder, antimony is sometimes used as a white pigment The most common industries to use it for that purpose are the porcelain and enamel industries that use it as an opacifier. Companies can purchase antimony is many ways like as a high purity antimony trioxide catalyst and as a result it is used in many final products. Almost everyone will come into contact with a product that used antimony oxide in the manufacturing process or contains antimony trioxide purposefully every day. It is a very useful material.

The Fantastically Hot Benefits of A Global Positioning System

Tuesday, April 21st, 2009 by www

To if you can save any money on your insurance by using GPS look at instant auto insurance quotes online. Man has always wandered about what is beyond what they know. Many travels and land discoveries were done because of this curiosity. Many lives though has been lost because of the uncertainties of their adventures and travels. Positioning and navigation are vital to so many activities and yet the process has always been unmanageable.

Luckily for us in this time and age is that we have new and innovative ways to help us and one of this is the GPS system.. GPS (global positioning system) is a complex technology but understanding. It can be easy if we take it one step at a time.

What is GPS?

Global Positioning System (GPS) is a universal navigation system formed from a constellation of 24 satellites and their ground stations. There are often more than 24 operational satellites as new ones are launched to substitute older satellites.

The satellite orbits repeatedly just about the same ground track (as the earth turns beneath them) once each day. The orbit altitude is such that the satellites repeat the same track and configuration over any point approximately each 24 hours (4 minutes earlier each day).

There are six orbital planes, equally spaced (60 degrees apart), and inclined at about fifty-five degrees with respect to the equatorial plan. The GPS system uses the ‘man-made’ stars as reference points to calculate accurate positions to a matter of meters.

The GPS system consists of a network of satellites, signals, ground based hardware and software, and people which make possible the identification of one’s precise location on the Earth’s surface. The Global Positioning System is funded by and controlled by the U. S. Department of Defense (DOD). While there are many thousands of civil users of GPS world-wide, the system was designed for and is operated by the U. S. military.

Over the years all kinds of technologies tried to make things easier but everybody failed to do so due to some disadvantages. Finally, the U. S. Department of Defense realized that military had to have an extremely accurate form of world wide positioning. And luckily they had the kind of money it took to build something really good. The result is the Global Positioning System, a system that’s changed navigation totally.

The accurateness of a location measurement using the global positioning system depends on the technology and features of the GPS receiver. High-end, survey-grade GPS receivers can determine locations precise to within centimeters. But even the low-end, commercial handheld receivers, may be accurate to within fifteen meters. GPS receivers have been miniaturized to just a few included circuits and so are becoming very economical. And that makes the technology easy to get to almost everyone.

Originally, commercial global positioning system units were precise for only about 100 meters because the military scrambled the signal–a program called Selective Availability. In the year 2000, the U.S. government detached Selective Availability, improving the accuracy of even basic handheld units to within fifteen meters. Today, with additional information from ground based correction services such as WAAS or U.S. Coast Guard differential GPS beacons, accuracy can be improved vividly.

A system of ground based reference station called the WAAS (Wide Area Augmentation Service) located across the United States. This station corrects them for inaccuracies caused by clock drift and by the atmosphere, and then broadcast this correct signal from a stationary satellite over the equator and receives global positioning system signals. GPS receiver prepared with the WAAS technology, plus lots of offered by GPS service providers, can receive and understand this corrective signal.

Now a days GPS is searching its way into vehicles like cars, boats, planes, construction equipment, movie making gear, farm machinery, and even laptop computers.

In next to no time, GPS will become nearly as basic as the telephones.

The Technology of GPS: It Is More Than Just An Electronic Device

Friday, April 17th, 2009 by www

Find out about auto insurance quote online here. Whenever we hear the term ‘Global Positioning System’, what would instantly come to our minds is a digital device with maps and other features that tells us our exact location in this planet. But do you know that such device is just one part of Global Positioning System? The device is called a Global Positioning System receiver, and while it is indeed an important Global Positioning System device, it is but a part of a very large and complex system that allows us to measure our exact location on earth.

The three-lettered term ‘Global Positioning System’ stands for Global Positioning System. It is a satellite based navigation system that has the ability to measure an object’s precise location on earth. The system was developed by the United States’ Department of Defense (DOD) and was officially called in the US military as the NAVSTAR GPR (Navigation Signal Timing and Ranging Global Positioning System). It was intended to be used for military operations only but has been opened for civilian use since the 1980s.

Global Positioning System is a very huge and complex system that may be divided into three segments: space, control, and user. The ’space’ segment of the Global Positioning System refers to its network of satellites that transmits the signals used for location identification. The ‘control’ segment, on the other hand, refers to the various stations on earth that maintains and controls the system. The ‘user’ segment refers to the Global Positioning System receivers the actual unit that we often mistake as the system.

SPACE

The ’space’ segment of the Global Positioning System is a constellation of 27 satellites that orbits the earth at some 12,000 miles above its surface. 24 of these satellites are in operation while the other 3 are on ’standby’ mode and will be used in case one fails. Each of the satellites orbits the earth twice in less than 24 hours, traveling at a speed of approximately 7,000 miles per hour.

Each of the satellite used in the Global Positioning System constellation weighs about 3,000 to 4,000 pounds. All of these satellites are solar-powered, although all have backup batteries onboard to be used in the absence of solar power (i.e., solar eclipse). Small rocket boosters are also used to keep the satellites flying on the correct path.

The signals being transmitted by the Global Positioning System satellites are low powered radio signals. These signals contain three different bits of information: a pseudorandom code, ephemeris data, and almanac data that are deciphered by the Global Positioning System receiver to obtain a precise measure of its location. The pseudorandom code tells the receiver which satellite is transmitting the signal while the ephemeris data provides information about the satellite’s position. The almanac data, on the other hand, contains information like the status of the satellite, current date and time.

CONTROL

The ‘control’ segment of the Global Positioning System refers to the various ground stations run by the US Department of Defense that controls various aspects of the system. In particular, these stations monitors the flight of the Global Positioning System satellites, synchronizes the satellite’s onboard atomic clocks, and uploads the data to be transmitted by the satellites.

USER

The ‘user’ segment of the Global Positioning System refers to the Global Positioning System receivers, whether they are used for military or civilian purposes. The Global Positioning System receiver is basically an electronic device that picks up the signal transmitted by the satellites and uses the information on those signals to figure out its precise location. Now that sounds simple! In reality, however, this function is a lot more complex.

The Global Positioning System receiver actually needs two things for it to figure out its location. First, it needs information about the location of at least three Global Positioning System satellites. Then, it would need to measure the distance between it and each of the three Global Positioning System satellites. The first information can be deciphered from the signal transmitted by the satellites while the second can be obtained by measuring the speed at which the signal was received.

ALL IN ONE SYSTEM

Combining the space, control, and user segments, we have a Global Positioning System that can tell us about our precise location here on earth.

You see, the Global Positioning System is not just the Global Positioning System receiver alone. It is a very big system, and a very complex one at that. But because every other part of the system is well maintained by the Department of Defense, we will never have to worry about those parts. All we have to do is to secure a Global Positioning System receiver and in an instant, we’ll receive information about our current location and other things that the receiver may want us to know.

After Years of Waiting The Aquamog CCX-238 Makes The Grade

Friday, April 17th, 2009 by www

The Aquamog was created in the early 1980’s by Aquatics Unlimited (AU). The McNabb family founded AU in the 1970

Both Tom and Dave McNabb created the aquamog brand and line of equipment throughout the 1980s and 1990s while with AU. Tom continued the Aquamog line into the new century with the addition of the MarshMog. Tom’s new company Clean Lakes, Inc. located in Martinez, California and Dave’s company DK Environmental in Lafayette, California have been working together on the Aquamog CCX project for about 10 yrs. and in Feb 2009 the Aquamog CCX was introduced into the Aquamog family.

The vessel know by others as the swamp cutter; swamp rig; cookie cutter; tule cutter; various other nicknames was in “no name land” so to speak. It did not fit the mold of conventional aquamogs as being a multi-purpose aquatic maintenance machine. But is has now worked its way into the Aquamog family of vessels.

With ten years of testing and rigorous evaluation Tom and Dave thought that the vessel without a name had finally proven itself as a true Aquamog. The Aquamog CCX-238 had meet all the critical tests to become an Aquamog. The Aquamog CCX-238 has now completed all the tests and is ready to stand side by side with the rest of the Aquamogs.

What makes the Aquamog CCX special is its ability to get into places that can not be reached by the MarshMog or the Aquaomg PRX-163 and Aquamog SRX-109. In addition it has been found that the Aquamog CCX system of removing aquatic emergent vegetation such as cattails and bulrush can be performed in a fraction of the time and more efficiently than with the other aquamogs. This equates to a savings for clients and users of the machines.

Like with the other Aquamogs the McNabb’s have a unique way of naming the aquamogs after their best attributes. The Aquamog CCX-238 is no different. The Aquamog CCX-238 gets its name from the 238 horse-power Detroit engine that it has humming under the back hood. The CCX stands for “Cookie Cutter eXtraordinaire”. The “Cookie Cutter” part of the name was picked due to its ability to cut channels through any type of aquatic emergent vegetation with easy, just like a cookie cutter through dough.

The following is a list of some of the other aquamog names and how they where derived.

Aquaomg PRX-163 – 163 Horse Power and PRX stands for “Power Rig eXtraordinaire”
Aquamog SRX-109 – 109 Horse Power and SRX stands for “Small Rig eXtraordinaire”
HarborMog HRX-109 109 Horse Power and HRX stands for “Harbor Rig eXtraordinaire”
Aquamog WRX-225 225 Horse Power and WRX stands for “Walking Rig eXtraordinaire”

So you see it was only fitting to give the Aquamog CCX-238 is proper name. All of the aquamogs that where made by the McNabb’s will be featured over the next few months in a series at www.aquamogs.com. Please check those site for more information on the other Aquamogs and projects that they have done all over the world.

MarshMog Can’t Be Stopped

Thursday, April 16th, 2009 by www

The MarshMog is a multi-purpose aquatic marsh rehab machine designed by a company called Clean Lakes located in Martinez, California. The Marshmog was first introduced in 2007.

The Marsh Mog is best equipped for aquatic vegetation removal in wetland areas. Marshes and wetlands most times can’t be accessed by water aquatic equipment such as the Aquamog, Cookie Cutter or Aquatic Weed Harvesters. As well land equipment such as backhoes, excavators and draglines can’t access most marshes & wetlands without building access roads which can destroy these sensitive aquatic ecosystem.

The Marshmog however has a ground pressure of 0.61 pounds per square inch. This is an amazingly low figure and is even less than most people just with their footprint. This equates to the most cost effective method of performing maintenance jobs in our sensitive aquatic habitats. The Marshmog can operate in wet soil types where humans can’t walk, and in water depths up to 2′two feet}.

The MarshMog can be used for many vegetation removal projects. It can be operated with various attachments that include mowers and brush grinders, as well as plows and discing attachments.

Precision aquatic herbicide applications can be completed by the Marshmog too. In areas that were only previously accessible for this type of work the Marshmog excels at a much lower cost per acre. The Marshmog is fitted with a GPS mapping system that collects the info needed to complete precision applications as well as mapping of the site for information purposes.

The Marshmog is the latest cutting edge aquatic maintenance tool created and designed by the same group who in the early 80s thought of and built the aqua mogs.

More info about the marshmog can be viewed by visiting www.marshmog.com. Also is you would like to find out more about the evolution and history of aquatic restoration equipment please visit www.aquamogs.com and www.aquamog.net.

Who Created the Aquamog?

Wednesday, April 15th, 2009 by www

The aquamog was created & designed in the early 80s by a firm in Martinez, California by the name of Aquatics Unlimited (AU). The team at AU, headed up by Thomas McNabb and James Nevrela, had the idea to invent a multi-purpose floating vessel that could perform a number of aquatic maintenance tasks. The name Aquamog was thought of by James Nevrela who was the engineer on the project. James was a Czechoslovakian by birth and immigrated to the United States by way of. James’s knowledge of the Mercedes Benz Uni-Mog, which is a multipurpose land vehicle that can go anywhere in most any conditions, was the source for the name Aquamog. AU’s goal in designing and developing the Aquamog was to have an aquatic vessel that could go anywhere in almost any condition. Thus name aquamog was croined. At the time the Aquamog was created and developed just for the AU contracting business.

The first Aquamog was engineered using an existing barge from an H10-800 aquatic weed harvester. This was done as an experiment to see if the Aquamog idea would even work. A removable skid was made that could be bolted to the barge of the H10-800. The top of the H10-800 was removed and the new skid attached and the first Aquamog was created. The skid has a backhoe type arm on the front an operators cab in the center and the engine with hydraulic components on the rear end. There were also two out riggers attached at the back of the skid. The propulsion for the Aquamog was the same paddle wheels used for the H10-800.

The operator’s area of the Aquamog comprised of a seat and a control panel. The first Aquamogs were designed around the physical dimensions of the first Aquamog operator Dave McNabb. So the first Aquamogs were all designed for Dave’s height as well as his arm span. This was not an issue until more Aquamogs were created by AU and sold. Some of the new operators where shorter and did not have Dave’s arm length either. Some could not touch their feet to the floor of the operators cab as well as reach all the controls efficiently.

Thus the first generation of aquamogs from the late 1980’s was an ever changing machine. Tom McNabb and Jim Nevrela made it a point to improve each Aquamog built with each new project that came along. This was the case until the early 1990’s when the first Aquamogs where produced and sold commercially. AU still utilized the Aquamog for its contracting business but there was a market developing for the Aquamog in parts of the United States and internationally.

More info about the history of the aquamogs can be found by going to aquamogs.com. There you will find numerous pictures of the early Aquamogs and descriptions of each of these machines. In addition info of projects completed by the Aquamog can be seen by going to aquamog.net. There is now one more entry into the “Mog” family and that is the Marshmog, which can be viewed by going to marshmog.com.

How Electric Power is Transported to A Residence

Thursday, April 9th, 2009 by www

You can find many advanced books on electricity generation that will give you tons of details. Really, there are entire college degrees that focus on electricity generation and delivery. If you are looking for extreme details on this, please check out your local library. Read on if you are looking for the basics.

Lets talk about what exactly electricity is before we start talking about how it is delivered to your house. Think of electricity as water flowing through a pipe or garden hose. The water is really electrons in the metal that makes up the wire. The hose is the wire that transports the water (electricity). This is just the basics.

After leaving the power plant, electricity is transported on power lines. It is more efficient to transport high voltages so the voltage on the lines is very high. Power lines form a huge system or grid that attaches everybody’s house and business to the power plants. In the United States, virtually the entire country is attached to the same grid. Texas is almost separate, but there are still a couple ties into the rest of the grid. All power plants add electricity into the system so if one plant goes down, there is still electricity because the other plants just put a little more in.

The power lines deliver voltage to transformers (usually a series of transformers) to change (step down) the voltage to 120V for you to use in your house. At your house, the power comes to one spot before being sent out to the rest of your house. This one common point is either a fuse box or a breaker box depending on how old your house is.

Traditionally, one electricity company took care of delivering energy to your house and you didn’t have to worry about picking your company. This was nice because it was one less thing to worry about. However, it can lead to higher costs for you.

Over the last few years, a different business model for electricity has started to emerge. It is a deregulated business model where multiple companies (one such company is ambit energy) sell electricity and have to compete for customers. In this model, one company or set of companies owns the power plants while a different set of companies is responsible for selling the electricity. Some states like Texas, New York, and Illinois allow non-monopolistic companies to essentially buy electricity from the power plants and sell it to consumers. In the place of large companies, small companies even individual people become Energy Consultants and are making a ton of money. Instead of a few big companies making a lot of money, this allows a lot of smaller companies and individuals to make money.

There is another trend out there that could change the way electricity is generated, or at least the amount that is delivered. residential solar power is starting to save people a ton of money by generating their own power.

How Electricity is Made at the Electric Company

Wednesday, April 8th, 2009 by www

There are many detailed articles and in fact entire books written about how electricity is generated and transmitted to houses and businesses. Heck, entire college courses cover this concept. If you are looking for extreme details on this, please check out your local library. Read on if you are looking for the basics.

Lets talk about what exactly electricity is before we start answering the question of how is electricity made. Think of electricity as water flowing through a pipe or garden hose. The water is really electrons in the metal that makes up the wire. The hose is the wire that transports the water (electricity). This is just the basics.

The first step is to create electricity at a power plant. To explain it simply, electricity is generated by magnets spinning inside a large coil of wires. The magnets spinning around cause electrons to move which creates electricity. What varies for each type of power plant is what causes the magnets to spin. This electricity producing machine is called a generator. The power created is measured in volts. You use 120 volts in your house, but the voltage levels on the power lines can be 300,000 to 400,000 volts or even more. Devices called transformers change the voltages by raising it at some points and lowering them at other times.

Most traditional electricity is generated using steam. Steam turbines are used to spin the magnets inside the coils of wire in the generator. The process starts with a boiler that heats water to create steam. The steam flows to the turbine causing it to spin. Picture water running over a water wheel and you have the concept. Steam flows through the pipes just like water through a hose. This spins the magnets inside the generator which creates electricity.

What changes in the boiler is the source of energy used to heat the water and make steam. Traditionally, fossil fuels like coal or oil are burned to create the heat needed to generate steam. While these resources are currently abundant, they will eventually run out and they pollute the environment. A more modern and potentially dangerous method of heating water to create steam is a nuclear reactor. They can be very efficient, but have the potential for almost unparalleled disaster. Many energy companies like ambit energy in Texas offer environmentally friendly power at competitive rates.

Today, there are a few more methods used to generate electricity. They use centuries old technology to turn the turn the magnets in the generators. First you have wind power being harnessed by large windmills. This type of power is usually used to supplement fossil fuel generated power or even power small communities, but it has not become “mainstream” as they say. You also have huge hydroelectric power plants that harness the power of moving water to generate electricity. Certain areas of the country use entirely water generated electricity. Both of these methods can be very expensive to start up, but the power plants don’t need to continue to buy fuel to burn to heat the water and make steam. They are only good in certain areas because if there is no wind or water there is no potential for generating electricity this way.

One last method of generating electricity worth mentioning is solar panels that make a solar energy home. Solar panels are mounted on a home to generate electricity for the house instead of getting it from the power lines. The technology is still really new and needs more development before it is a really good option for homeowners to generate electricity.

After the electricity is generated, it gets delivered to your house so you can use it to power your life. The nice thing is that all you have to do is pay your energy company and they take care of the rest.
