Abstract
345,284. Fuel igniters. HODGE, D., 170, Piccadilly, London, and ESCHBACH, W., Troisdorf, near Cologne, Germany. Nov. 11, 1929, No. 34399. [Class 50.] Insensitive heating compositions of carbon dioxide and like blasting cartridges are ignited by the intermediary of more easily ignitible compositions. The igniter shown comprises an electrically ignited match 7, a primary charge 13 of lead thiocyanate and potassium perchlorate, and a secondary charge 10 of iron and potassium permanganate. A space 14 is left between the match 7 and the primary charge 13, and a passage 8 is provided for the escape of the products of combustion.
