Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
141 words
GAS DISCHARGE APPARATUS WHEREIN A HIGH-CURRENT RING DISCHARGE IS INDUCED IN GAS IN A VESSEL BY THE APPLICATION OF A SHORT HIGH-VOLTAGE PULSE FROM A FIRST ENERGISING CIRCUIT TO A PRIMARY WINDING OF A PULSE TRANSFORMER WHEREOF SAID RING DISCHARGE FORMS A SINGLE TURN SECONDARY WINDING CHARACTERISED IN THAT THERE IS PROVIDED A SECOND ENERGISING CIRCUIT ADAPTED TO PRODUCE A RELATIVELY LOW VOLTAGE OUTPUT OF RELATIVELY LONG DURATION ARRANGED TO BE COUPLED TO SAID SECONDARY WINDING IN ORDER TO MAINTAIN THE DISCHARGE CURRENT AT A HIGH VALUE FOR A PROLONGED PERIOD WHEN THE SHORT HIGH-VOLTAGE PULSE HAS FALLEN TO A LOW VALUE, AND IN THAT SAID FIRST AND SECOND ENERGISING CIRCUITS ARE CONNECTED IN SERIES ACROSS THE SAME PRIMARY WINDING, SAID LOW VOLTAGE OUTPUT BEING MADE AVAILABLE IN THE SERIES CIRCUIT PRIOR TO THE COMMENCEMENT OF SAID SHORT HIGH VOLTAGE PULSE.
