Abstract

812,257. Ammunition primers. DYNAMIT ACTIENGESBLLSCHAFT VORM A. NOBEL & CO. Oct. 30, 1957 [April 20, 1957], No. 33818/57. Addition to 805,118. Class 9(1) The electric primer described in the parent Specification is modified by placing plastic metal foil 5 between the canductive part 7 of the priming charge 8 and the electrode 3. The foil 5 may be placed between the two parts of the charge or metal foil 5 may be placed on both sides of the conductive charge. Alternatively the foils 5 may be placed over and under the whole of the priming charge and are then of synthetic plastic impregnated with conductive varnishes containing graphite or metal powder.
