Controlled rectifier ignition system

Claim 1

AN IGNITION SYSTEM FOR AN INTERNAL COMBUSTION ENGINE COMPRISING, A SOURCE OF DIRECT CURRENT VOLTAGE, AN IGNITION COIL HAVING A PRIMARY WINDING AND A SECONDARY WINDING, STARK DISTRIBUTING MEANS CONNECTED BETWEEN SAID SECONDARY WINDING AND SPARK PLUGS ON SAID ENGINE FOR SUPPLYING SPARK ENERGY TO THE SPARK PLUGS OF SAID ENGINE, A CONTROLLED RECTIFIER HAVING ANODE, CATHODE AND GATE ELECTRODES, SAID CONTROLLED RECTIFIER BEING OF A TYPE WHICH CAN BE TURNED ON IN ITS ANODE-CATHODE CIRCUIT WHEN ITS GATE HAS A HIGHER POTENTIAL THAN IS CATHODE AND BEING OF A TYPE WHICH IS TURNED OFF IN ITS ANODE-CATHODE CIRCUIT WHEN THE PONTENTIAL OF ITS CATHODE IS HIGHER THAN THE POTENTIAL OF ITS GATE, MEANS CONNECTING THE ANODE AND CATHODE ELECTRODE OF SAID CONTROLLED RECTIFIER AND SAID PRIMARY WINDING OF SAID IGNITION COIL IN SERIES ACROSS SAID SOURCE OF DIRECT CURRENT AND PULSE GENERATING MEANS INCLUDING A COIL WINDING CONNECTED ACROSS THE GATE AND CATHODE ELECTRODES OF SAID CONTROLLED RECTIFIER AND A ROTOR CARRYING CIRCUMFERENTIALLY SPACED PERMANENT MAGNETS WHICH HAVE OPPOSITE MAGNETIC POLARITIES RELATIVE TO SAID COIL WINDING DRIVEN BY SAID ENGINE FOR INDUCING IN SAID COIL WINDING A SERIES OF SPACED, DISCRETE PAIRS OF SUCCESSIVE ALTERNATING CURRENT PULSES, THE PULSES OF EACH PAIR BEING OF OPPOSITE PHASE RELATIONSHIP AND THE PERIOD OF EACH PULSE PAIR BEING OF A TIME DURATION LESS THAN THE PERIOD BETWEEN SUCCESSIVE PULSE PAIRS.
