Abstract

424,449. Blasting - cartridges. DE WENDEL & CIE, LES PETITS FILS DE F., 3, Rue Paul Baudry, Paris. Jan. 23, 1934, No. 2328. Convention date, Jan. 31, 1933. Drawings to Specification. [Class 9 (i)] A blasting-charge comprises a cartridge of water mixed with a powder, or filings, or chips of iron or other metal, and a heat-producing primer to produce the instantaneous vaporization of the water. The mixed water and metallic powder &c., may be mixed with an absorbent such as sawdust, cork powder, infusorial earth, or mineral wool or sponge, and may be wrapped in a sheet of zinc or aluminium, or enclosed in a non-leaking metallic tube. The primer may comprise liquid oxygen and metallic powders, with or without hydrocarbons. Several charges may be used in the same bore-hole.
