Ignition system employing a fast high magnetic buildup

Claim 1

AN AUXILIARY IGNITION CONTROL DEVICE FOR USE IN IGNITION SYSTEMS OF INTERNAL COMBUSTION AND LIKE ENGINES COMPRISING AN IGNITION TRANSFORMS COIL FOR ACCUMULATING MAGNETIC ENERGY INCLUDING A PRIMARY WINDING HAVING A PLURALITY OF TAPPED PORTIONS, A SOURCE OF VOLTAGE SUPPLY, A CIRCUIT BREAKING MEANS, AN ELECTRICAL MAIN CIRCUIT INCLUDING SAID PRIMARY WINDING, SAID VOLTAGE SOURCE AND SAID CIRCUIT BREAKING MEANS IN SERIES FOR RECURRENTLY CLOSING AND OPENING SAID MAIN CIRCUIT TO CONTROL THE RATE OF INPUT CURRENT PULSES EFFECTING A RECURRENT STORAGE OF ENERGY FROM SAID SOURCE, THE DURATION OF SAID INPUT PULSES INCLUDES A FIRST AND SECOND TRANSITION PERIODS, INCLUDING IN COMBINATION, AN AUXILIARY SWITCHING DEVICE CONNECTED IN PARALLEL WITH ANY OF SAID TAPPED PORTIONS OF SAID PRIMARY WINDING WITH INCLUSION OF SAID VOLTAGE SOURCE FORMING AN AUXILIARY CIRCUIT, SAID AUXILIARY SWITCHING DEVICE SELECTIVELY INSERTING ANY OF SAID TAPPED PORTIONS INTO SAID CIRCUIT BREAKING AND OPEN SAME IMMEDIATELY AFTER SAID CIRCUIT BREAKING MEANS CLOSES AND HAVING A SPEED RESPONSIVE DEVICE ADAPTED TO CONTROL THE TAPPING CONNECTION TO ANY OF SAID TAPPED PORTIONS OF SAID PRIMARY WINDING BECOMING EFFECTIVE IN SAID AUXILIARY CIRCUIT IN RESPONSE TO MECHANICAL MEANS CONTROLLED BY THE SPEED OF SAID ENGINE, SAID AUXILIARY SWITCHING DEVICE OPENS ANY OF SAID PORTIONS OF SAID PRIMARY WINDING JUST PRIOR THE CURRENT REACHES ITS NORMAL STEADY-STATE VALUE DEMANDED BY SAID WHOLE PRIMARY WINDING ALLOWING TO REACH IN SAID MAIN CIRCUIT AT THE END OF SAID SECOND TRANSISTION PERIOD A SUBSTANTIALLY CONSTANT STEADY-STATE CURRENT IRRESPECTIVE OF THE RAPIDITY OF SAID INPUT PULSES.
