Surge current limiter for the split phase capacitor a. c. compressor motor of a domestic air conditioner

Claim 1

A SURGE CURRENT LIMITER FOR CONNECTING A SPLIT PHASE CAPACITOR A.C. MOTOR OF A DOMESTIC AIR CONDITIONER TO A DOMESTIC POWER LINE, SAID LIMITER COMPRISING: (A) A HIGH WATTAGE SURGE CURRENT LIMITING RESISTOR, (B) A LOW WATTAGE HOLDING RESISTOR, (C) CIRCUIT MEANS FOR CONNECTING THE SURGE CURRENT LMITING RESISTOR PERMANENTLY IN SERIES BETWEEN THE MOTOR AND THE DOMESTIC POWER LINE SO LONG AS POTENTIAL IS SUPPLIED BY THE POWER LINE SO AS OT LIMIT STARTING CURRENT SUPPLIED TO THE MOTOR, (D) A NORMALLY OPEN SWITCH CONNECTED IN SHUNT WITH THE SURGE CURRENT LIMITING RESISTOR, (E) A HEAT RESPONSIVE ELEMENT CONTROLLING THE NORMALLY OPEN SWITCH AND OPERABLE TO CLOSE THE SWITCH WHEN HEATED, (F) CIRCUIT MEANS FOR CONNECTING THE HOLDING RESISTOR TO THE DOMESTIC POWER LINE SO AS TO PERMANENTLY ENERGIZE THE HOLDING RESISTOR SO LONE AS POTENTIAL IS SUPPLIED BY THE POWER LINE, (G) BOTH OF SAID RESISTORS BEING PHYSICALLY LOCATED IN HEATED EXCHANGE RELATIONSHIP WITH THE HEAT RESPONSIVE ELEMENT SO THAT WHEN POTENTIAL IS SUPPLIED BY THE POWER LINE THE SURGE CURRENT LIMITING RESISTOR INITIALLY WILL LIMIT THE CURRENT SUPPLIED TO THE MOTOR AND THEREAFTER THE HEAT GENERATED BY THE RESISTORS WILL OPERATE THE HEAT RESPONSIVE ELEMENT TO CLOSE THE NORMALLY OPEN SWITCH AND SHUNT THE SURGE CURRENT LIMITING RESISTOR WHICH THEREAFTER IS HELD CLOSED BY THE HEAT GERERATED BY THE HOLDING RESISTOR.
