Abstract
1,248,432. Seismic cartridges. HERCULES Inc. 8 Oct., 1968 [9 Oct., 1967 ; 29 April, 1968], No. 13837/71. Divided out of 1,248,431. Heading F3A. [Also in division H4] The description is included in the Specification 1,248,431, but the claims relate to a complete seismic charge assembly ready for firing, comprising (a) a closed cartridge shell containing 1/8 to 3 pounds of a nitrocarbonitrate charge as the main explosive charge and (b) a primer device in the form of a closed elongated shell containing an ignition charge which is percussion initiated and is confined on an end wall of the elongated shell, a high explosive base charge, and an intermediate primer charge which detonates in response to ignition of the ignition charge and which, in turn, detonates the base charge.
