Abstract: A gas generant composition includes a fuel, at least 25 wt % of which is an alkali, alkaline earth, and/or transition metal salt of dicyanamide and an oxidizer which is an ammonium, alkali metal and/or alkaline earth metal salt of a chlorate, perchlorate or nitrate.

Abstract: In a gas generant composition for automotive airbag inflation, a gas generant composition comprises a fuel and an oxidizer the composition includes a metal oxide or metalloid oxide and a processing aid which is a mixture of mica and a salt of a fatty acid.

Abstract: A gas generant composition contains as a fuel a mixture of a major portion of a triazole or tetrazole and a minor portion of a water soluble fuel; and an oxidizer component, at least 20 wt % of said oxidizer component being a transition metal oxide, such as CuO.

Abstract: A gas generant composition contains as a fuel a mixture of a major portion of a triazole or tetrazole and a minor portion of a water soluble fuel; and an oxidizer component, at least 20 wt % of said oxidizer component being a transition metal oxide, such as CuO. Generant compositions in accordance with the invention autoignite in a range around 170.degree. C., providing autoignition of the generant without the need for separate autoignition devices. Also, the generant compositions are useful as autoignition pyrotechnic in autoignition devices.

Abstract: A sheet dispenser for dispensing thin film such as collagen film for wrapping food. The dispenser consists of a cabinet in which a row of collagen film is supported on rollers and the film is pulled off the roll by driven rollers. When a predetermined length has been pulled off the roll it is severed by a hot wire system in which the hot wire is located between rollers and supported in a tension head controlled by spring. A cutter bar supported on pivoted arms moves across so as to press the film against the hot wire during the cutting action.

Abstract: Propellant containing an oxidizer, a binder, and 2-hydroxymethyl-1,3-propanediol as a plasticizer.

Abstract: Binders for propellants for the like comprise elastomers which are based on block copolymers in which a pair of poly(caprolactone) blocks flank a central hydroxyl-terminated poly(butadiene) block. The block polymers are cured with isocyanates through the OH termini of the poly(caprolactone) blocks. The elastomers have inherent energies and other characteristics intermediate those of PCP and HTPB and have good compatibility with nitrate ester plasticizers.

Abstract: Poly(caprolactone) polymers are provided having molecular weights of 4000 or higher, are used to form propellant binders. When the high molecular weight poly(caprolactone) polymers are used in propellant formulations and cured with isocyanates of adequate functionality, propellants are produced having improved stress and strain characteristics relative to presently formulated propellants having binders of cured, lower molecular weight poly(caprolactone) polymers.

Abstract: A prepolymer for use in preparing a binder for low vulnerability gun propellants. The condensation of an alkynediol and formaldehyde produces a prepolymer which is cured with a polyisocyanate. The resulting binder can be combined with 1,3,5,7-tetramethylenetetranitramine (HMX) or 1,3,5-trimethylenetrinitramine (RDX), and is readily extruded as multi-perforated propellant grains, the extruded material having a greatly reduced tendency to slumping, and an enhanced mass impetus value.
