  • Spark circuit
    Patent number: 4327310
    Abstract: A spark circuit for heating equipment used on automobiles in which a switch interrupts current flow in the primary of an ignition coil. A comparator compares the actual value of current flowing in the primary against a predetermined nominal value, and current to the switch is interrupted when the values reach parity, so as to render the switch non-conductive during the interruption with resulting auto-induction in the secondary of the ignition coil.
