Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
127 words
A TIMING NETWORK COMPRISING: INPUT AND OUTPUT MEANS; AN ELECTRICAL CURRENT PATH SHUNTING SAID OUTPUT MEANS, SAID CURRENT PATH INCLUDING A TRANSISTOR DEVICE AND A CONTROLLED RECTIFIER DEVICE IN SERIES COMBINATION SO THAT SAID PATH IS COMPLETED ONLY WHEN BOTH OF SAID DEVICES ARE CONDUCTIVE; A RELAXATION OSCILLATOR CIRCUIT HAVING A PRESELECTED PERIOD OF OSCILLATION AND PROVIDING AN OUTPUT A PRESELECTED TIME AFTER INITIATION OF OPERATION; INPUT SWITCHING MEANS RESPONSIVE TO AN APPLIED SIGNAL FOR SIMULTANEOUSLY RENDERING SAID RELAXATION OSCILLATOR CIRCUIT OPERATIVE AND SAID TRANSISTOR DEVICE CONDUCTIVE; AND MEANS APPLYING THE OUTPUT OF SAID RELAXATION OSCILLATOR CIRCUIT TO SAID CONTROLLED RECTIFIER DEVICE OPERATIVE TO RENDER SAID CONTROLLED RECTIFIER DEVICE CONDUCTIVE A FIXED TIME AFTER APPLICATION OF SAID INPUT SIGNAL SO THAT SAID OUTPUT MEANS IS SUBSTANTIALLY DE-ENERGIZED.
