Abstract

1361727 Detonator pellets SCHAFFLER & CO 14 Sept 1972 [17 Sept 1971] 42697/72 Heading F3A A detonator pellet comprises a bridgewire 7 and electrically conducting blades 3 and 4 connected together by an electrically insulating plastics coating 9, which fills the space therebetween and encapsulates detonating composition 8. The coating 9 is coloured according to the type of detonator with which the pellet is to be used. The pellet is made by cutting the blades from a strip of tinned brass 1, soldering the wire 7 to turned over ends of the blades, severing the wire, immersing the individual wires in detonating composition, immersing the so-formed pellets in the plastics coating composition, and severing the individual pellets from the strip.
