Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
147 words
IN A GASEOUS DISCHARGE TUBE SYSTEM, A FIRST SERIES CIRCUIT COMPRISING A DISCHARGE TUBE AND THE PRIMARY OF A TRANSFORMER, AN ALTERNATING VOLTAGE SOURCE CONNECTED ACROSS SAID FIRST SERIES CIRCUIT, SUBSTANTIALLY ALL OF THE VOLTAGE FROM SAID SOURCE BEING INITIALLY APPLIED ACROSS SAID TUBE PERMITTING SAID TUBE TO START, AN INCREASED PORTION OF THE VOLTAGE FROM SAID SOURCE BEING APPLIED ACROSS SAID PRIMARY AND A DECREASED PORTION OF THE VOLTAGE FROM SAID SOURCE BEING APPLIED ACROSS SAID TUBE AFTER SAID TUBE STARTS, THE DECREASED PORTION OF THE VOLTAGE ACROSS SAID TUBE BEING SUFFICIENT TO MAINTAIN CONDUCTION OF SAID TUBE, AND A SECOND SERIES CIRCUIT COMPRISING A DISCHARGE TUBE AND BALLAST MEANS, SAID SECOND SERIES CIRCUIT BEING CONNECTED ACROSS THE SECONDARY OF SAID TRANSFORMER, THE INCREASED PORTION OF THE VOLTAGE ACROSS SAID PRIMARY CAUSING AN INCREASED VOLTAGE ACROSS SAID SECONDARY WHICH IS SUFFICIENT TO START SAID SECOND TUBE.
