Abstract

656,315. Gas-generating charges. HUTCHISON, A. C., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Dec. 29, 1948, No. 33379. [Class 9 (ii)] Gas generating units comprise in association nitroguanidine and/or guanidine nitrate, at least one non-explosive inorganic reagent, which in sufficient amount is able to effect the self-sustained decomposition of nitroguanidine and/or guanidine nitrate when locally heated producing gases which contain condensable organic compounds, e.g. molybdic acid, ceric oxide, vanadium pentoxide, and selenium dioxide, and a heatresisting filamentary material of high specific surface, such as asbestos, or iron, steel, or platinum fine wire gauze, say not less than 0.25 per cent of the weight of the composition if included therein. The filamentary material is positioned in immediate proximity to the burning surface so that the gases formed pass thereover or therethrough, and if external to the surface the heatresisting material may include the inorganic reagent. The amount of inorganic reagent with guanidine nitrate may be reduced by the inclusion of a non-explosive organic reagent such as tartaric maleic, or fumaric acids, or glucose. The compositions may include reagents which increase the temperature of the evolved gases, e.g. ammonium nitrate or perchlorate, and may be in powder granular or compact form. Specifications 430,258, 627,724 and 644,073 are referred to. The Provisional Specification describes the non-explosive organic reagents as alternative to the non-explosive inorganic reagents.
