Capacitive discharge ignition system capable of multiple sparking at slow-engine speeds

Claim 1

AN IGNITION SYSTEM FOR AN INTERNAL COMBUSTION ENGINE TO PROVIDE A SPARK IN A SPARK GAP DISPOSED IN AN ENGINE CYLINDER, WHEREBY TO IGNITE A COMBUSTIBLE MIXTURE IN SAID CYLINDER, SAID SYSTEM COMPRISING: AN INDUCTION COIL WHICH INCLUDES A PRIMARY AND A SECONDARY WINDING, SAID SPARK GAP BEING OPERATIVELY CONNECTED TO THE SAID SECONDARY WINDING; CAPACITANCE MEANS; POWER SUPPLY MEANS PROVIDING A D.C. OUTPUT; MEANS, AND CONNECTING SAID PRIMARY WINDING, SAID CAPACITANCE MEANS, AND SAID POWER SUPPLY MEANS IN A FIRST SERIES CIRCUIT SO AS TO CHARGE SAID CAPACITOR MEANS; TRIGGER MEANS ACTUABLE BY A CONTROL SIGNAL CONNECTED IN A SECOND SERIES CIRCUIT WITH SAID CAPACITANCE MEANS AND SAID PRIMARY WINDING SO AS TO ALLOW SAID CAPACITANCE MEANS TO DISCHARGE THROUGH SAID PRIMARY WINDING ONLY WHEN SAID TRIGGER MEANS IS ACTUATED; A PULSING MEANS FOR PROVIDING AN ELECTRICAL PULSE OF A DURATION PROPORTIONAL TO ENGINE SPEED; MULT-VIBRATORY MEANS OPERATIVELY CONNECTED TO SAID PULSING MEANS WHEREBY TO BE ACTUABLE BY SAID ELECTRICAL PULSE TO PRODUCE AN OSCILLATORY CONTROL SIGNAL HAVING A FREQUENCY INHERENT WITHIN THE MULTI-VIBRATOR MEANS FOR THE DURATION OF SAID ELECTRICAL PULSE; MEANS APPLYING SAID OSCILLATORY CONTROL SIGNAL TO SAID TRIGGER MEANS; WHEREBY SAID TRIGGER MEANS IS REPETITIVELY ACTUATED AT SAID FREQUENCY OF SAID OSCILLATORY CONTROL SIGNAL, THEREBY REPETITIVELY DISCHARGING SAID CAPACITANCE MEANS AT SAID FREQUENCY OF SAID OSCILLATORY CONTROL SIGNAL DURING THE TIME THE ELECTRICAL PULSE ACTUATES SAID MULTI-VIBRATOR MEANS.
