Abstract: A propellant for guns includes at least one energy carrier, nitrocellulose and cellulose acetate butyrate. At least part of the nitrocellulose is alcohol-soluble nitrocellulose. The nitrocellulose serves as a binder and for that purpose is present in a concentration of at least 15% by weight in the propellant. A process for producing a propellant is also provided.

Abstract: The invention provides an infra-red decoy flare comprising a pyrotechnic composition which comprises an extrudable and energetic binder in an amount in the range of from 4-35 wt %, which binder comprises a nitrocellulose, an oxidator in an amount in the range of from 40-80 wt %, a pyrotechnic fuel in an amount in the range of from 15-35 wt %, and a carbon source in an amount of up to and including 10 wt %, all amounts based on total pyrotechnic composition. The invention further provides a process for preparing said infra-red decoy flare.

Abstract: An apparatus comprises a vehicle occupant protection device (14) and a gas generating material (18). The gas generating material (18), when ignited, produces a combustion gas that actuates the vehicle occupant protection device (14). The gas generating material (18) comprises a single-base nitrocellulose composition that includes greater than 2%, by weight of the single-base composition, stabilizer. The stabilizer is a urea of an aromatic amine.

Abstract: Methods to recover nitramines from energetic materials yielding useable by-products and producing zero waste. The methods are used on materials containing HMX and RDX.

Abstract: An apparatus comprises a vehicle occupant protection device and a gas generating material, which, when ignited, produces gas to actuate the vehicle occupant protection device. The gas generating material comprises a cubane compound having the general formula: wherein R is selected from the group consisting of H and NO2.

Abstract: A non-toxic primer composition for center-fire cartridges which provides improved ballistic data and is void of metallic oxidizing compounds. It is comprised of a mixture of about 10-30% by weight of nitrocellulose and/or a double based propellant such as Hercules Fines, approximately 30-75% by weight of two percussion-sensitive compounds such as DDNP and tetracene, and approximately 10-30% by weight of calcium silicide. The mixture provides improved propellant ignition and non-toxic ignition products, and minimizes misfires in that it contains no hygroscopic compounds.

Abstract: Explosive compositions based on TNT (trinotrotoluene) having incorporated therein as desensitizer an ozokerite wax.

Abstract: A primer composition using manganese dioxide as the predominant oxidizer is disclosed. The manganese dioxide oxidizer is combined with a fuel source and non-metallic initiating explosive material. Various diazo, triazole, or tetrazole compounds may be used as non-metallic initiating explosives, although diazodinitrophenol is preferred. The combustion by-products of the invention do not include toxic oxides of lead, barium, or mercury. The invention therefore provides distinct safety and environmental advantages.

Abstract: The invention relates to a cast explosive composition having a relatively high density and energy and a critical diameter no larger than about 150 mm at a temperature of 5.degree. C. The composition comprises inorganic oxidizer salt consisting primarily of ammonium nitrate, a water-immiscible organic liquid fuel, less than about 5% water, a sensitizer and an emulsifier which allows formation of a water-in-oil emulsion at an elevated formulation temperature but which also allows the emulsion to weaken and the inorganic oxidizer salt to crystallize at lower or ambient temperatures to produce a cast composition.

Abstract: A high density emulsion blasting agent and method is provided for increasing volume energy and optimizing booster sensitivity of water-in-oil emulsion blasting agents without loss of desirable handling characteristics of invert emulsions by utilizing an effective amount of a special sensitizing formulation in total or partial substitution for gas entraining density control agents.

Abstract: A gas generating propellant charge which is made by piling explosive powder sheets having a plurality of projections on at least one surface thereof so as to make contact them with each other is excellent in firing characteristics, and the explosive powders in the gas generating propellant charge can be burnt in a short time, thereby generating a large amount of gas.

Abstract: Explosive or propellant powder which include a cation exchange polymer having alkali metal ions bound thereto, and method of preparation.

Abstract: Propellant inhibitors are provided for cellulose-containing particulate solid propellants, and particularly for nitrocellulose-containing gun propellants, in which the inhibitor is the reaction product of a polyfunctional isocyanate such as polymethylene polyphenyl isocyanate and a polyol such as polyethylene glycol.
