1293948 Firing explosive charges MESSERSCHMITT-BOLKOW-BLOHM GmbH 29 Dec 1969 [11 Jan 1969] 63096/69 Heading H2H A circuit for detonating an explosive charge comprises an electric repeater coil coupling, the winding of which consists of two coils connected in series and oppositely wound. In the circuit shown, a source 20 applies a voltage to a detonating device 12 by way of coils 11, 21, each of which comprises oppositely wound windings 111, 112; 211, 212 respectively. Magnetic shields 13, 14 are also provided. The windings 111, 112 not only prevent accidental detonation by external magnetic fields, but also short-circuit the device 12 to prevent detonation by electrostatic charges. The windings may be formed as concentric coils on a plug-and-socket connection, Fig. 1 (not shown), or as pancake coils, Fig. 2 (not shown). The arrangement may be used in a missile launching system.
