Electric system for discharge device utilizing resonant circuit to provide constant current output

Claim 1

AN ELCTRIC SYSTEM COMPRISING AN ELECTRIC DISCHRGE DEVICE OPERATIVE BY SHORT HIGH INTENSITY PULSES OF CURRENT, A CAPACITOR, A TRANSFORMER HAVING A CORE, ONE WINDING ON THE CORE CONSTRUCTED AND ARRANGED FOR CONNECTION TO A SOURCE OF ALTERNATING CURRENT OF PREDETERMINED FREQUENCY, THE VOLTAGE OF WHICH MAY BE FLUCTUATING, A SECOND WINDING ON THE CORE CONNECTED IN SERIES WITH THE FIRST WINDING AND THE TWO WINDINGS CONNECTED IN PARALLEL WITH THE CAPACITOR, THE REACTANCE OF THE SERIES CONNECTED WINDINGS AT LEAST APPROXIMATING THE REACTANCE OF THE CAPACITOR SO THAT A RESONANT CIRCUIT IS FORMED THEREWITH, THE RESONANT CIRCUIT OPERATING AT A FREQUENCY EQUAL TO THE FREQUENCY OF THE VOLTAGE IMPRESSED ON THE FIRST WINDING SO THAT THE POTENTIAL ACROSS THE CAPACITOR IS MAINTAINED SUBSTANTIALLY CONSTANT IRRESPECTIVE OF FLUCTUATIONS IN THE INPUT VOLTAGE, AND SWITCHING MEANS CONNECTED IN SERIES WITH THE DISCHARGE DEVICE ACROSS THE CAPACITOR, THE SWITCHING MEANS OPERATIVE AFTER THE ALTERNATING CURRENT HAS REACHED ITS PEAK VALUE TO SUDDENLY DISCHARGE THE CAPACITOR THROUGH THE DISCHARGE DEVICE WHEREBY THE OUTPUT OF THE ELECTRIC DISCHARGE DEVICE IS SUBSTANTIALLY CONSTANT IRRESPECTIVE OF FLUCTUATIONS IN THE INPUT VOLTAGE.
