Claim 1
Independent Claim
168 words
AN ELECTRIC CONTROL CIRCUIT INCLUDING IN COMBINATION: INPUT TERMINAL MEANS FOR CONNECTING THE CONTROL CIRCUIT TO A SOURCE OF ALTERNATING-CURRENT VOLTAGE; OUTPUT TERMINAL MEANS, A FIRST TRANSFORMER HAVING A PRIMARY WINDING CONNECTED TO SAID INPUT TERMINAL MEANS AND HAVING A SECONDARY WINDING; A SECOND TRANSFORMER HAVING A PRIMARY WINDING AND HAVING A SECONDARY WINDING; CIRCUIT MEANS INCLUDING THE PRIMARY OF SAID SECOND TRANSFORMER CONNECTING SAID INPUT TERMINAL MEANS TO SAID OUTPUT TERMINAL MEANS; SWITCHING MEANS CONNECTED TO SAID SECONDARY WINDING OF SAID SECOND TRANSFORMER FOR SELECTIVELY REDUCING THE IMPEDANCE OF THE PRIMARY WINDING OF SAID SECOND TRANSFORMER SO AS TO INCREASE THE CURRENT FLOW THERETHROUGH; A PAIR OF CONTROL TERMINALS FOR CONNECTING THE CONTROL CIRCUIT ACROSS A VARIABLE IMPEDANCE SENSING ELEMENT; MEANS FOR CONNECTING THE SECONDARY WINDING OF SAID FIRST TRANSFORMER TO ONE OF SAID CONTROL TERMINALS; AND MEANS FOR CONNECTING THE OTHER OF SAID CONTROL TERMINALS OF SAID SWITCHING MEANS TO ACTUATE SAID SWITCHING MEANS IN RESPONSE TO A VARIATION IN THE IMPEDANCE OF SAID SENSING ELEMENT.
