Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
120 words
A STARTING CIRCUIT FOR POSITIVELY STARTING A GASEOUS ELECTRIC DISCHARGE DEVICE A PREDETERMINED TIME AFTER THE CIRCUIT IS ENERGIZED COMPRISING A SOURCE OF ELECTRIC CURRENT, SWITCH MEANS FOR COUPLING SAID DEVICE TO SAID SOURCE OF CURRENT, A BALLAST REACTOR COUPLED TO SAID DEVICE, A TIME DELAY CIRCUIT MEANS FOR PERMITTING PREHEATING CURRENT TO FLOW THROUGH THE ELECTRODES OF SAID DEVICE AFTER THE CLOSING OF SAID SWITCH MEANS, AND MEANS FOR SUBSTANTIALLY SIMULTANEOUSLY TERMINATING SAID PREHEATING AND CAUSING SAID BALLAST REACTOR TO ALWAYS PRODUCE ITS INITIAL VOLTAGE DISCHARGE ACROSS THE ELECTRODES OF SAID DEVICE AT SUBSTANTIALLY THE PEAK VALUE OF THE CURRENT CYCLE TO POSITIVELY START SAID DEVICE UPON THE INITIAL APPLICATION OF VOLTAGE ACROSS SAID ELECTRODES BY SAID BALLAST REACTOR.
