Abstract: An apparatus (10) comprises a vehicle occupant protection device (14), and an actuator (10) for the vehicle occupant protection device (14). The actuator (10) includes a gas generating material (18) or both a gas generating material (18) and an autoignition material (66). The gas generating material (18), the autoignition material (66), or both the gas generating material (18) and the autoignition material (66) comprise a plasticized cyclodextrin nitrate ester. The plasticized cyclodextrin nitrate ester has an autoignition temperature in the range of about 150° C. to about 180° C. and is resistant to thermal decomposition at a temperature less than 150° C.

Abstract: This invention relates to liquid propellant compositions containing an enetic material of organic nitrate esters. The organic nitrate esters of the present invention are complexed with a nitrate ester plasticizer, bismuth subsalicylate, and stabilizer to form liquid compositions with an appropriate energy, stability, and sensitivity that is useful as a propellant.

Abstract: An explosive composition is derived from a non-aqueous emulsion of a solution of a self-explosive dispersed as the discontinuous phase (D-phase) throughout a continuous phase (C-phase) which is substantially immiscible with the D-phase. The emulsion is prepared by dropping the solution of self-explosive into a dispersion of surfactant or emulsifier in fuel, at a temperature high enough to prevent precipitation of the self-explosive from solution. Upon cooling and aging, the emulsion becomes a pourable or pumpable mass which gradually is destabilized. Upon destabilization and recrystallization in a cavity, a mass of crystals of self-explosive becomes shaped to the cavity.

Abstract: Emulsion explosive compositions comprising a discontinuous aqueous oxidizer salt phase and a continuous carbonaceous fuel phase and from about 5% to about 50% nitrostarch are disclosed which exhibit increased resistance to precompression or dead pressing while maintaining high detonation velocities.

Abstract: The present invention provides a method for producing a water-in-oil emulsion and the emulsion explosives therefrom containing nitrostarch by nitrating starch with an excess of a nitrating agent, treating the reaction mixture thereof with anhydrous ammonia to form a solution of water, dissolved ammonium nitrate, and nitrostarch, and thereafter combining the aqueous solution with a carbonaceous fuel phase and emulsifier to form a water-in-oil emulsion. The explosive is provided, preferably, by the distribution of voids throughout the water-in-oil emulsion to render it detonable. The invention is also applicable to the production of melt-in-fuel explosive compositions and water-gel explosives.
