Electrical apparatus

Claim 2

APPARATUS FOR GENERATING A SUCCESSION OF ELECTRICAL PULSES, COMPRISING A STORAGE CONDENSER, A CHARGING CIRCUIT FOR THE CONDENSER, A CIRCUIT FOR PERIODICALLY DISCHARGING THE CONDENSER, SAID DISCHARGING CIRCUIT INCLUDING A SOLID STATE ELECTRONIC SWITCHING DEVICE SELECTIVELY RENDERED ELECTRICALLY CONDUCTIVE AND NON-CONDUCTIVE, SAID SWITCHING DEVICE HAVING AN ANODE, A CATHODE AND A CONTROL ELECTRODE, AND TRIGGERING MEANS FOR CONTROLLING THE SWITCHING DEVICE, SAID TRIGGERING MEANS FOR CONTROLLING A COIL WINDING CONNECTED IN PARALLEL WITH A VOLTAGE BREAKDOWN DIODE ACROSS THE CATHODE AND CONTROL ELECTRODE OF SAID SWITCHING DEVICE AND MEANS FOR GENERATING A SUCCESSION OF ELECTRICAL TRIGGERING PULSED IN SAID WINDING TO RENDER THE ANODE-CATHODE PATH OF SAID SWITCHING DEVICE ELECTRICALLY CONDUCTIVE TO THE CHARGE ON SAID STORAGE CONDENSER.

Claim 3

AN IGNITION SYSTEM FOR AN INTERNAL COMBUSTION ENGINE HAVING AT LEAST ONE CYLINDER, COMPRISING A STORAGE CONDENSER, A CHARGING CIRCUIT FOR CONDENSER, A CIRCUIT FOR PERIODICALLY DISCHARGING THE CONDENSER, AN OUTPUT CIRCUIT CONNECTED TO BE ENERGIZED BY THE DISCHARGE OF THE STORAGE CONDENSER, THE OUTPUT CIRCUIT INCLUDING AT LEAST ONE IGNITER GAP AND SAID DISCHARGING CIRCUIT INCLUDING A SOLID STATE ELECTRICALLY CONTROLLED SWITCHING DEVICE SELECTIVELY RENDERED ELECTRICALLY CONDUCTIVE AND NON-CONDUCTIVE, SAID SWITCHING DEVICE INCLUDING A CONTROL MEANS WHICH WHEN RAISED TO A PREDETERMINED MINIMUM POSITIVE POTENTIAL RENDERS THE SWITCHING DEVICE ELECTRICALLY CONDUCTIVE AND BEING ELECTRICALLY NON-CONDUCTIVE UNLESS THE CONTROL MEANS IS RAISED TO SAID MINIMUM POTENTIAL, AND TRIGGERING MEANS INCLUDING MEANS DRIVEN IN SYNCHRONISM WITH THE ENGINE FOR GENERATING ELECTRICAL TRIGGERING PULSES AND MEANS FOR GENERATING A SUCCESSION OF TIMED POSITIVE ELECTRICAL PULSES AND FOR DELIVERING SUCH TIMED PULSES TO THE CONTROL MEANS OF THE SWITCHING DEVICE, THE FIRST PORTION OF THE VOLTAGE WAVE FORM OF EACH OF SAID TRIGGERING PULSES PLOTTED AGAINST ENGINE CRANKSHAFT DEGREES BEING GENERALLY IN THE SHAPE OF THE FIRST PORTION OF THE POSITIVE HALF OF A SINE WAVE AND THE AMPLITUDE OF SUCH VOLTAGE WAVE FORM AND THE LENGTH OF ITS BASE ALONG THE ZERO VOLTAGE AXIS OF THE WAVE FORM BEING VARIABLE IN THE SAME DIRECTION AS THE SPEED OF THE ENGINE, WHEREBY THE STORAGE CONDENSER BEGINS TO DISCHARGE AND THE IGNITER GAP IS ENERGIZED EARLIER IN THE ENGINE CYCLE AS THE SPEED OF THE ENGINE INCREASES.

Claim 4

AN IGNITION SYSTEM FOR AN INTERNAL COMBUSTION ENGINE HAVING AT LEAST ONE CYLINDER, COMPRISING A STORAGE CONDENSER, A CHARGING CIRCUIT FOR CONDENSER, A CIRCUIT FOR PERIODICALLY DISCHARGING THE CONDENSER, AN OUTPUT CIRCUIT CONNECTED TO BE ENERGIZED BY THE DISCHARGE OF THE STORAGE CONDENSER, THE OUTPUT CIRCUIT INCLUDING AT LEAST ONE IGNITER GAP AND SAID DISCHARGING CIRCUIT INCLUDING A SOLID STATE ELECTRICALLY CONTROLLED SWITCHING DEVICE SELECTIVELY RENDERED ELECTRICALLY CONDUCTIVE AND NON-CONDUCTIVE, SAID SWITCHING DEVICE INCLUDING A CONTROL MEANS WHICH WHEN RAISED TO A PREDETERMINED MINIMUM POSITIVE POTENTIAL RENDERS THE SWITCHING DEVICE ELECTRICALLY CONDUCTIVE AND BEING ELECTRICALLY NON-CONDUCTIVE UNLESS THE CONTROL MEANS IS RAISED TO SAID MINIMUM POTENTIAL, AND TRIGGERING MEANS INCLUDING MEANS DRIVEN IN SYNCHRONISM WITH THE ENGINE FOR GENERATING ELECTRICAL TRIGGERING PULSES AND MEANS FOR GENERATING A SUCCESSION OF TIMED POSITIVE ELECTRICAL PULSES AND FOR DELIVERING SUCH TIMED PULSES TO THE CONTROL MEANS OF THE SWITCHING DEVICE, THE FIRST PORTION OF THE VOLTAGE WAVE FORM OF EACH OF SAID TRIGGERING PULSES PLOTTED AGAINST ENGINE CRANKSHAFT DEGREES BEING GENERALLY IN THE SHAPE OF THE FIRST PORTION OF THE POSITIVE HALF OF A SINE WAVE AND THE AMPLITUDE OF SUCH VOLTAGE WAVE FORM AND THE LENGTH OF ITS BASE ALONG THE ZERO VOLTAGE AXIS OF THE WAVE FORM BEING VARIABLE IN THE SAME DIRECTION AS THE SPEED OF THE ENGINE, WHEREBY THE STORAGE CONDENSER BEGINS TO DISCHARGE AND THE IGNITER GAP IS ENERGIZED EARLIER IN THE ENGINE CYCLE AS THE SPEED OF THE ENGINE INCREASES.
