Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
122 words
IN A TELEVISION RECEIVER, A VERTICAL DEFLECTION CIRCUIT COMPRISING AMPLIFYING MEANS HAVING AN INPUT TERMINAL AND AN OUTPUT TERMINAL, VERTICAL DEFLECTION WINDINGS COUPLED TO SAID OUTPUT TERMINAL, A CAPACITOR COUPLED TO SAID AMPLIFIER INPUT TERMINAL, A PRIMARY CURRENT SUPPLY COUPLED TO SAID CAPACITOR FOR CHARGING SAID CAPACITOR DURING THE TRACE PORTION OF EACH DEFLECTION CYCLE. DISCHARGING MEANS COUPLED TO SAID CAPACITOR FOR PERIODICALLY DECOUPLING SAID CURRENT SUPPLY FROM SAID CAPACITOR AND FOR RIGIDLY DISCHARGING SAID CAPACITOR AND AUXILIARY CHARGING MEANS COUPLED TO SAID CAPACITOR FOR PERIODICALLY RECHARGING SAID CAPACITOR RAPIDLY TO PROVIDE SUFFICIENT VOLTAGE AT SAID INPUT TERMINAL OF SAID AMPLIFYING MEANS TO INITIATE CONDUCTION IN SAID AMPLIFYING MEANS SUBSTANTIALLY AT THE COMMENCEMENT OF THE TRACE PORTION OF EACH VERTICAL DEFLECTION CYCLE.
