Abstract:
This invention relates to a packaged luminescent material, and more particularly to a combined package of a chemiluminescent agent as the ''''fuel,'''' and an activating agent therefor, wherein the fuel and activating agent are maintained in close association but separated from each other by a barrier medium to prevent interaction before the same is desired. When the barrier medium is ruptured, or otherwise broken down, either deliberately or unintentionally, a reaction occurs between the chemiluminescent agent and the activating agent with the emission of visible light, without, however, the generation of any appreciable amount of heat.
Abstract:
This invention relates to a low cost spontaneous decomposition catalyst for hydrazine or mixtures containing hydrazine-hydrazine nitrate propellant fuels, which permits a low temperature ignition of the fuels and retains its activity after exposure to the propellant flame environment. The catalyst is produced by coating rhenium metal or a rhenium-molybdenum mixture on a support body such as alumina. Iron, nickel, copper, silver, gold, iridium, or ruthenium may be included as co-catalyst metals.
