Abstract
528,035. Explosives. HERCULES POWDER CO. June 8, 1938, No. 17048. Convention date. July 6, 1937. [Class 9 (ii)] A progressive burning smokeless powder is prepared by coating smokeless powder grains with an admixture of a non-volatile non-explosive organic material, which is a non-solvent for the nitrocellulose but compatible therewith, and either a volatile or non-volatile solvent for said nitrocellulose. The expression " compatible therewith" is defined as meaning that the deterrent and the nitrocellulose of the smokeless powder are capable of existing together as a homogeneous system. The mixture may be rendered more fluid by (1) using a suitable emulsifying agent to form an aqueous emulsion thereof, (2) employing a volatile vehicle which is not a solvent for the smokeless powder grains or (3) forming an aqueous emulsion of such a volatile vehicle extended mixture. The smokeless powder grains when coated with the admixture are preferably treated with water at a point of incipient adherence of said grains to each other in order to prevent said adherence. Numerous examples of the various constituents of the mixture are given in the Specification together with a number of ways of preparing the smokeless powder. Specification 15865/93, [Class 9], is referred to.
