Clothes drier control apparatus

Claim 1

CONTROL APPARATUS OPERABLE IN RESPONSE TO THE ELECTRICAL RESISTANCE OF FABRICS WHICH ARE TOSSED ABOUT IN A RANDOM MANNER WHILE BEING DRIED IN THE DRUM OF A CLOTHES DRIER, COMPRISING LOAD CIRCUIT MEANS INCLUDING A VOLTAGE SOURCE, A LOAD, A VOLTAGE-RESPONSIVE BISTABLE DEVICE AND MEANS CONNECTING SAID SOURCE, LOAD AND BISTABLE DEVICES IN SERIES, CONTROL VOLTAGE MEANS INCLUDING A CAPACITOR CONNECTED WITH SAID BISTABLE DEVICE FOR CONTROLLING THE STATE OF OPERATION THEREOF AND THE STATE OF ENERGIZATION OF SAID LOAD CIRCUIT MEANS, MEANS CHARGING SAID CAPACITOR TO A POTENTIAL THAT IS A FUNCTION OF THE INSTANTANEOUS ELECTRICAL RESISTANCE OF THE FABRICS AT A GIVEN TIME, SAID CHARGING MEANS INCLUDING A SOURCE OF CHARGING VOLTAGE CONNECTED WITH SAID CAPACITOR, MEANS FOR DISCHARGING SAID CAPACITOR AT A CONSTANT PREDETERMINED RATE, MEANS MOUNTED ON SAID DRUM IN INTERMITTENT CONTACT WITH SAID FABRICS FOR CONNECTING AT RANDOM THE RESISTANCE PRESENTED BY SAID FABRICS IN SERIES INTERMEDIATE SAID SOURCE OF CHARING VOLTAGE AND SAID CAPACITOR, WHEREBY THE SAID CAPACITOR IS CHARGED AT RANDOM AT A RATE DETERMINED BY SAID RESISTANCE PRESENTED BY SAID FABRICS, SAID MEANS FOR DISCHARGING SAID CAPACITOR INCLUDING A FIRST RESISTOR CONNECTED IN PARALLEL WITH SAID CAPACITOR TO DEFINE A PARALLEL BRANCH A FIRST TERMINAL OF WHICH IS CONNECTED WITH A FIRST TERMINAL OF SAID CHARGING VOLTAGE SOURCE VIA SAID MEANS IN TERMITTENT CONTACT WITH SAID FABRICS, AND A SECOND RESISTOR CONNECTED IN SERIES INTERMEDIATE THE OTHER TERMINALS OF SAID PARALLEL BRANCH AND SAID CHARGING VOLTAGE SOURCE, SAID BISTABLE DEVICE BEING RESPONSIVE TO THE VOLTAGE ACROSS SAID FIRST TERMINAL OF SAID PARALLEL BRANCH AND THAT END OF SAID SECOND RESISTOR WHICH IS CONNECTED WITH SAID CHARGING VOLTAGE SOURCE.
