Title: Field explosive charge with igniter - has electric primer with variable time control, using RC time delay
Inventor: STRELOW KARLHEINZ
IPC: F42D1/05
Filed: 1979-04-24
Abstract: The electric igniting element forms central part of a circuit which consists of a power source, e.g. a battery which is connected to the circuit when the trigger is activated. The battery current flows at the same time to an igniting capacitor and load resistor, as well as to the time delay lement (4). This current is not sufficient to directly fire the igniting element, being at least 10% below the required level. The igniting element can only be fired, when current flows through a conductor due to closing of an electronic switch, under the control of the time delay element, which becomes activated when the parallel capacitor has been fully charged. A light emitting diode incorporated in the circuit, may indicate the current flow. The whole unit has a long service if rechargeable battery is used.
