ABSTRACT:
An electrostatically dischargeable primer which in a preferred embodiment is characterized by an electrically non-conductive plastic case having a base end, an open end and a powder cavity filled with powder, an electrically conductive metallized plastic, or carbon-filled, or metal electrode extending through the base and the plastic case and communicating with the powder cavity and an electrically conductive membrane seal closing the open end of the non-conductive plastic case and sealing the powder cavity. In a first preferred embodiment a concave tower receptacle is defined in the base of the non-conductive plastic case opposite the conductive membrane seal to interface with the electrode tower and positive electrode of an ignition coil. In a second preferred embodiment the tower receptacle is eliminated in favor of a flat base, through which the electrode projects. The electrostatically dischargeable (electric) primer may be mounted in any desired cartridge and the cartridge or cartridges seated in a firing plate to facilitate both single and multiple burst sequences by operation of the corresponding ignition coil or coils. Electrical interrogation and firing pulses may be applied to the electric primer by the ignition coil to ascertain the nature, location and type of electric primer and cartridge under consideration and to fire the electric primer, respectively.
