Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
156 words
A CONTROL CIRCUIT COMPRISING, IN COMBINATION, A SOURCE OF ALTERNATING CURRENT, LOAD MEANS ENERGIZED BY THE ALTERNATING CURRENT SOURCE, CONTROLLED RECTIFIER MEANS CONNECTED BETWEEN SAID ALTERNATING CURRENT SOURCE AND SAID LOAD MEANS, SAID CONTROLLED RECTIFIER MEANS BEING NORMALLY NON-CONDUCTIVE TO BLOCK CURRENT FLOW TO THE LOAD MEANS AND HAVING ELECTRODE CONTROL MEANS TO RENDER IT CONDUCTIVE, ACTUATING MEANS CONNECTED TO SAID ALTERNATING CURRENT SOURCE AND TO SAID ELECTRODE CONTROL MEANS APPLYING A CONTROL SIGNAL TO SAID ELECTRODE CONTROL MEANS AT A PREDETERMINED TIME IN EACH ALTERNATING CURRENT CYCLE, SAID ACTUATING MEANS INCLUDING A CAPACITANCE AND FIRST RESISTANCE CONNECTED TOGETHER IN SERIES, VOLTAGE SENSITIVE SWITCH MEANS CONNECTED ACROSS SAID CAPACITANCE, AND A SECOND RESITANCE CONNECTED BETWEEN THE LOAD SIDE OF SAID CONTROLLED RECTIFIER MEANS AND THE JUNCTION OF SAID CAPACITANCE AND SAID FIRST RESISTANCE, AND MEANS CONNECTED WITH SAID CONTROLLED RECTIFIER MEANS AND SAID LOAD MEANS FOR PROVIDING A HIGH VOLTAGE STARTING PULSE ON SAID LOAD MEANS.
Claim 2
Dependent Claim
156 words
A CONTROL CIRCUIT COMPRISING, IN COMBINATION, A SOURCE OF ALTERNATING CURRENT, LOAD MEANS ENERGIZED BY THE ALTERNATING CURRENT SOURCE, CONTROLLED RECTIFIER MEANS CONNECTED BETWEEN SAID ALTERNATING CURRENT SOURCE AND SAID LOAD MEANS, SAID CONTROLLED RECTIFIER MEANS BEING NORMALLY NON-CONDUCTIVE TO BLOCK CURRENT FLOW TO THE LOAD MEANS AND HAVING ELECTRODE CONTROL MEANS TO RENDER IT CONDUCTIVE, ACTUATING MEANS CONNECTED TO SAID ALTERNATING CURRENT SOURCE AND TO SAID ELECTRODE CONTROL MEANS APPLYING A CONTROL SIGNAL TO SAID ELECTRODE CONTROL MEANS AT A PREDETERMINED TIME IN EACH ALTERNATING CURRENT CYCLE, SAID ACTUATING MEANS INCLUDING A CAPACITANCE AND FIRST RESISTANCE CONNECTED TOGETHER IN SERIES, VOLTAGE SENSITIVE SWITCH MEANS CONNECTED ACROSS SAID CAPACITANCE, AND A SECOND RESITANCE CONNECTED BETWEEN THE LOAD SIDE OF SAID CONTROLLED RECTIFIER MEANS AND THE JUNCTION OF SAID CAPACITANCE AND SAID FIRST RESISTANCE, AND MEANS CONNECTED WITH SAID CONTROLLED RECTIFIER MEANS AND SAID LOAD MEANS FOR PROVIDING A HIGH VOLTAGE STARTING PULSE ON SAID LOAD MEANS.
Claim 3
Dependent Claim
142 words
A CIRCUIT FOR CONTROLLING ENERGIZATION OF A LOAD FROM AN ALTERNATING CURRENT SUPPLY COMPRISING, IN COMBINATION, CONTROLLED RECTIFIER MEANS COMPRISING A TRIAC ELECTRICALLY CONNECTED BETWEEN THE LOAD AND THE ALTERNATING CURRENT SUPPLY, SAID TRIAC BEING NON-CONDUCTIVE TO BLOCK CURRENT FLOW TO THE LOAD AND HAVING A SINGLE CONTROL ELECTRODE TO RENDER IT CONDUCTIVE, AND ACTUATING MEANS FOR APPLYING A CONTROL SIGNAL TO SAID CONTROL ELECTRODE TO RENDER SAID TRIAC CONDUCTIVE, SAID ACTUATING MEANS INCLUDING A RESISTANCE AND A CAPACITANCE ELECTRICALLY CONNECTED TOGETHER IN SERIES AND TO THE ALTERNATING CURRENT SUPPLY, A VOLTAGE SENSITIVE SWITCH MEANS CONNECTED ACROSS SAID CAPACITANCE AND IN SERIES WITH SAID RESISTANCE, AND CONNECTED TO SAID CONTROL ELECTRODE, SO THAT THE RESISTANCE-CAPACITANCE CIRCUIT DETERMINES THE TIME IN EACH ALTERNATING CURRENT CYCLE AT WHICH SAID VOLTAGE SENSITIVE SWITCH BECOMES CONDUCTIVE AND A CONTROL SIGNAL IS APPLIED TO SAID CONTROL ELECTODE.
Claim 4
Dependent Claim
142 words
A CIRCUIT FOR CONTROLLING ENERGIZATION OF A LOAD FROM AN ALTERNATING CURRENT SUPPLY COMPRISING, IN COMBINATION, CONTROLLED RECTIFIER MEANS COMPRISING A TRIAC ELECTRICALLY CONNECTED BETWEEN THE LOAD AND THE ALTERNATING CURRENT SUPPLY, SAID TRIAC BEING NON-CONDUCTIVE TO BLOCK CURRENT FLOW TO THE LOAD AND HAVING A SINGLE CONTROL ELECTRODE TO RENDER IT CONDUCTIVE, AND ACTUATING MEANS FOR APPLYING A CONTROL SIGNAL TO SAID CONTROL ELECTRODE TO RENDER SAID TRIAC CONDUCTIVE, SAID ACTUATING MEANS INCLUDING A RESISTANCE AND A CAPACITANCE ELECTRICALLY CONNECTED TOGETHER IN SERIES AND TO THE ALTERNATING CURRENT SUPPLY, A VOLTAGE SENSITIVE SWITCH MEANS CONNECTED ACROSS SAID CAPACITANCE AND IN SERIES WITH SAID RESISTANCE, AND CONNECTED TO SAID CONTROL ELECTRODE, SO THAT THE RESISTANCE-CAPACITANCE CIRCUIT DETERMINES THE TIME IN EACH ALTERNATING CURRENT CYCLE AT WHICH SAID VOLTAGE SENSITIVE SWITCH BECOMES CONDUCTIVE AND A CONTROL SIGNAL IS APPLIED TO SAID CONTROL ELECTODE.
