The air between two panes slows the transfer of heat. Filling the air space with an inert gas — argon— improves a window's performance by further slowing the rate at which heat is transferred from one pane to the other. Argon gas is an odorless, invisible and non-toxic gas with a thermal conductivity that is 30% less than air.

The hotter the filament the more efficient the lamp. The upper limit to filament temperature is the boiling point of tungsten. High pressure (around 100 PSI!) gas filling raises the boiling point. This allows a higher filament temperature, greater visible light output and increased efficiency.

Gas cylinders are shipped brand new. Due to the varying policies from supplier to supplier we encourage our customers to find out the policy of the gas distributor they intend to buy from locally.

Miniature high pressure gas filled lamps have much shorter thicker filaments than vacuum lamps. Short, thick wires are much stronger than the long thin filaments typical of vacuum lamps.

HID (High Intensity Discharge) is the technology in which the filament of the Halogen Bulb is replaced with Xenon gas. When high voltage is applied, the gas generates an arc of light. The Xenon gas generates 3x more light than standard halogen Bulbs. Most companies do produce gas-filled halogen Bulbs. These Bulbs do consist of a filament, but the gas gives off a bluer color.

Our high-performance bulbs by Nokya, Polarg and Raybrig are very high end versions of what came in your car and just plugging them in will provide a noticeable improvement in your night vision but HID lights are far and above brighter, more vivid and provide the maximum output possible. Literally 3x more light than halogen bulbs. High Intensity Discharge (H.I.D.) is a type of lighting technology that replaces the filament of the light bulb with Xenon gas.

This depends on the amount of fuel being transported. To transport a road legal container with a capacity under 1000 litres, a general understanding of the ADR 'Carriage of Dangerous Goods' regulations is required. The driver should be aware of equipment and vehicle marking requirements and also be aware of emergency procedures to follow in the event of an accident.

With strips of wood that are glued as apposed to the filler method that cracks and drops through after a while.

We will fax the prescription to the pharmacy of your choice prior to your leaving the clinic. We have all of the local 24 hour pharmacies on speed dial to allow you to pick up your medicine on the way home.

All orders originating within North America are filled from a pharmacy with licensed pharmacists. International orders may get filled from a partner pharmacy licensed to do business within Europe and other countries around the world.

Yes, it takes a while to get used to, but you will be able to hit with even more top-spin and back-spin with the moveable mass racket.

A layer of 10kt (or better) Real Gold Bullion is mechanically bonded under heat and pressure to one or more surfaces of a supporting base metal, then rolled or drawn to a given thickness.

part of my $18,500 entry fee, the Dakar organization supplies me with gas for the race sections or, "Special Sections", as they are called. I will be responsible for all fuel during the liaisons. My bike will be capable of carrying around 9 gallons of gas at a fill-up and at around 30mpg I will be able to average around 270 miles per tank on a liaison. During the race sections mileage will be dramatically less due to the sand and high-revving conditions.

For any suspected gas emergency, or questions regarding a gas odor or carbon monoxide, please call us immediately at 1-800-427-2200. For additional safety information check our safety section.
