A finishing material for wood made of a resin dissolved in a volatile solvent such as alcohol. The varnish is brushed or sprayed on a surface, and it forms a hard, resin film when the solvent evaporates from it.
Industry:Aviation
A finishing material used to restore resilience to an old dope film. Rejuvenator contains strong solvents to open up the dried-out dope film and plasticizers to restore resilience to the old dope.
Industry:Aviation
A finishing material used to shrink cotton or linen fabric and make it airtight and weatherproof. Dope is made of a cellulose film base mixed with suitable solvents, thinners, and plasticizers.
Industry:Aviation
A finishing material whose film base is made of a cellulose material dissolved in nitric acid. Nitrate dope has good encapsulating properties, but it is being replaced by cellulose acetate butyrate (CAB) dope, because it is far more flammable than CAB dope.
Industry:Aviation
A fire and overheat detection system in which a gas-releasing element and a pressure switch are sealed in a stainless steel tube installed so it surrounds the compartment being protected.
If the tube is exposed to a fire or an overheat condition, the element releases gas and closes the pressure switch. This actuates the fire warning system.
Industry:Aviation
A fire detection system that uses individual thermoswitches installed around the inside of the area to be protected. These thermoswitches are wired in parallel between two separate circuits. A short or an open can exist in either circuit without disabling the system or causing a fire warning.
Industry:Aviation
A fire detection system that works on the principle of the rate-of-temperature-rise. Thermocouples are connected in series and installed in various locations in the area to be protected. One thermocouple is surrounded by insulation that prevents its temperature changing rapidly.
In the event of a fire, the temperature of all the thermocouples except the protected one will rise immediately and a fire warning will be initiated. In the case of a general overheat condition, the temperature of all the thermocouples will rise uniformly and since there is no temperature difference between the thermocouples, there will be no fire warning.
Industry:Aviation
A fire extinguisher that carries the extinguishing agent in a sealed sphere or cylinder. When the agent-discharged switch is closed, a powder charge drives a cutter through a frangible disk and releases the agent. The entire contents of the container is emptied in much less than a second.
Industry:Aviation
A fire extinguisher that holds carbon dioxide gas under a pressure of about 800 to 900 pounds per square inch.
When carbon dioxide, CO2, is sprayed on a fire, it comes out of the extinguisher in the form of a snow and blankets the fire. The snow changes into CO2 gas and pushes away all the oxygen. When there is no more oxygen to combine with the fuel, the fire goes out.
