Claim 1
Independent Claim
138 words
AN ADJUSTABLE REMOTE CONTROL VOLTAGE CIRCUIT COMPRISING ADJUSTABLE VOLTAGE MEANS CONNECTIBLE TO A SOURCE OF ALTERNATING CURRENT FOR PRODUCING AN OUTPUT VOLTAGE, MEANS CONNECTED TO THE ADJUSTABLE VOLTAGE MEANS HAVING ONE PATH WHICH UPON ENERGIZATION INCREASES THE OUTPUT VOLTAGE AND ANOTHER PATH WHICH UPON ENERGIZATION DECREASES THE OUTPUT VOLTAGE, PROPORTIONAL MEANS CONNECTED TO THE VOLTAGE MEANS FOR PRODUCING A VOLTAGE PROPORTIONAL TO THE OUTPUT VOLTAGE, ADJUSTABLE MEANS FOR PRODUCING A SUBSTANTIALLY CONSTANT ADJUSTABLE VOLTAGE, COMPARING MEANS FOR COMPARING THE TWO VOLTAGES TO PRODUCE A SIGNAL INDICATIVE OF THE DIFFERENCE BETWEEN THE TWO-VOLTAGES BOTH AS TO MAGNITUDE AND SENSE AND MEANS RESPONSIVE TO THE SIGNAL OF THE COMPARING MEANS FOR ENERGIZING ONE PATH OR THE OTHER TO ALTER THE OUTPUT VOLTAGE TO A VALUE SELECTED BY THE ADJUSTING MEANS TO THEREBY SUBSTANTIALLY REDUCE THE DIFFERENCE BETWEEN THE TWO VOLTAGES.
