Circuit arrangement for igniting ignitrons

Claim 1

A CIRCUIT FOR IGNITING AN IGNITRON HAVING AN ANODE, AN IGNITION ELECTRODE AND A CATHODE WHICH FROM AN IGNITION PATH, SAID CIRCUIT COMPRISING A CAPACITOR, MEANS FOR SUPPLYING UNIDIRECTIONAL CURRENT TO SAID CAPACITOR THEREBY TO STORE AN ELECTRICAL CHARGE THEREON, A DISCHARGE CIRCUIT FOR SAID AN CAPACITOR COMPRISING A CONTROL DEVICE HAVING A CONTROL ELECTRODE AND FIRST AND SECOND ELECTRODES FOR ESTABLISHING A UNIDIRECTIONAL CURRENT PATH, AN IGNITION CIRCUIT COMPRISING FIRST AND SECOND PARALLEL CONNECTED BRANCHES, SAID FIRST BRANCH COMPRISING A FIRST PORTION OF AN INDUCTOR IN SERIES WITH THE IGNITION PATH OF SAID IGNITRON, SAID SECOND BRANCH COMPRISING A RECTIFIER ELEMENT IN SERIES WITH A SECOND PORTION OF SAID INDUCTOR, SAID FIRST AND SECOND BRANCHES TOGETHER FORMING A CLOSED UNIDIRECTIONAL CIRCUIT WITH SAID IGNITRON IGNITION PATH AND WHICH INCLUDES BOTH PORTIONS OF SAID INDUCTOR, CIRCUIT MEANS CONNECTED TO A POINT ON SAID INDUCTOR FOR COMPLETING THE DISCHARGE CIRCUIT OF SAID CAPACITOR, MEANS COUPLED TO SAID CONTROL ELECTRODE FOR PERIODICALLY RENDERING SAID CONTROL DEVICE CONDUCTIVE THEREBY TO DISCHARGE SAID CAPACITOR THROUGH SAID DISCHARGE CIRCUIT, AND MEANS FOR INTERCONNECTING SAID DISCHARGE CIRCUIT WITH SAID IGNITION CIRCUIT WHEREBY IN RESPONSE TO THE DISCHARGE OF SAID CAPACITOR A CURRENT FLOW IS INITIATED IN SAID INDUCTOR ELEMENT AND BETWEEN SAID IGNITION ELECTRODE AND SAID CATHODE IN A DIRECTION SO AS TO IGNITE SAID IGNITRON, SAID RECTIFIER ELEMENT BEING POLED SO THAT FOLLOWING THE DISCHARGE OF SAID CAPACITOR THE ENERGY STORED IN SAID INDUCTOR ELEMENT CONTINUES TO MAINTAIN SAID CURRENT FLOW IN SAID DIRECTION TO IGNITE SAID IGNITRON.
