US Classification:
149 48
Abstract:
There is provided a gas generating composition consisting essentially of a mixture of nitroguanidine and phase stabilized ammonium nitrate. When the ammonium nitrate is phase stabilized with from about 7% to about 20%, by weight, of a potassium salt, the mixture is structurally and volumetrically stable over typical automotive operating temperatures and has a melting temperature in excess of 100. degree. C. The mixture generates large volumes of nitrogen and carbon dioxide when ignited with minimal generation of solids or toxic gases and is particularly useful as an inflating medium for automobile airbags.

Assignee:
Olin Corporation - Redmond WA
International Classification:
A62C 3502
US Classification:
169 11
Abstract:
There is disclosed an a flame suppressing composition and an apparatus for suppressing a fire. The composition contains a propellant and an effective amount of magnesium carbonate. One apparatus directs the effluent of a propellant at a mixture of ice and water to generate superheated steam. Preferably, the effluent is a mixture of hot gases and solid particulate directed by a nozzle to impinge upon the mixture of ice and water.

International Classification:
A62C 500
US Classification:
169 12
Abstract:
There is disclosed an apparatus for suppressing a fire. The apparatus includes a gas generator containing as a propellant, a mixture of a fuel, strontium nitrate as an oxidizer, and magnesium carbonate. When the propellant is ignited, a nitrogen rich effluent is generated that is effective to suppress the fire. By providing the propellant with at least 35%, by weight, of magnesium carbonate, the generation of effluent by-products that are corrosive to aluminum is inhibited.

International Classification:
C06B 4510 C06B 3500
US Classification:
149 196
Abstract:
A low temperature autoigniting composition for use in a mobile occupant restraint system comprising, a low temperature melting oxidizer and a fuel, wherein the low temperature autoigniting composition autoignites in the temperature range of about 130. degree. C. to about 175. degree. C. In a preferred embodiment, the composition comprises a low temperature melting oxidizer, a fuel, and a catalyst, wherein the composition autoignites in the temperature range of about 130. degree. C. to about 150. degree. C. Preferably, the oxidizer comprises about 20 to about 70 percent by weight of the composition, the fuel comprises about 10 to about 50 percent by weight of the composition, and the catalyst comprises about 2 to about 50 percent by weight of the composition. The autoignition propellants of the invention are designed to function at low temperatures and before heat damage to an airbag deployment mechanism can occur, for example, during a fire.

International Classification:
C06B 4500
US Classification:
149 2
Abstract:
A two component, high temperature, thermally stable explosive composition comprises a liquid or low melting oxidizer and a liquid or low melting organic fuel. The oxidizer and fuel in admixture are incapable of substantial spontaneous exothermic reaction at temperatures on the order of 475. degree. K. At temperatures on the order of 475. degree. K. , the oxidizer and fuel in admixture have an activation energy of at least about 40 kcal/mol. As a result of the high activation energy, the preferred explosive compositions are nondetonable as solids at ambient temperature, and become detonable only when heated beyond the melting point. Preferable oxidizers are selected from alkali or alkaline earth metal nitrates, nitrites, perchlorates, and/or mixtures thereof. Preferred fuels are organic compounds having polar hydrophilic groups. The most preferred fuels are guanidinium nitrate, acetamide and mixtures of the two.
Azide-Free Gas Generant Compositions And Processes

International Classification:
C06B 9500
US Classification:
102289
Abstract:
Composition and process for inflating an automobile or aircraft occupant safety restraint bag which reduces the toxicity of the gases produced by gas generants. A relatively low energy nitrogen containing fuel is combined with a burn rate accelerator, such as an alkali metal salt, to form an azide-free gas generant composition which lowers the combustion temperature of the gas generants while also maintaining a rapid burn rate, thereby reducing toxicity of the resultant gases.
