  • Means for and a method of initiating explosions
    Patent number: 4422379
    Abstract: An alternating current generator for use as a shot exploder suitable for firing electric detonators coupled through toroid transformers e.g. `Magnadet` detonators. The detonating system is energized by means of a signal that is automatically generated at the resonant frequency, thus avoiding the usual time-consuming and dangerous practice involving in-situ determination of inductance and selection of capacitors.
