Thermostat with an improved heat anticipation means

Claim 1

A THERMOSTAT COMPRISING, TEMPERATURE RESPONSIVE MEANS, A BASE, A RESISTANCE HEATER, A SUPPORT MEMBER MOUNTING SAID HEATER HAVING A RELATIVELY HIGH THERMAL CONDUCTIVITY, COMMON SUPPORT MEANS CONNECTED TO SAID BASE FOR SUPPORTING SAID RESPONSIVE MEANS AND SAID SUPPORT MEMBER ON SAID BASE SO SAID HEATER IS ADJACENT SAID RESPONSIVE MEANS, SAID SUPPORT MEANS AND SAID SUPPORT MEMBER PROVIDING A HEAT CONDUCTION PATH BETWEEN SAID HEATER AND SAID RESPONSIVE MEANS, SWITCH MEANS OPERABLY CONNECTED TO SAID RESPONSIVE MEANS, AND CIRCUIT MEANS ADAPTED TO CONNECT SAID SWITCH MEANS AND SAID HEATER TO A SOURCE OF POWER WHEREBY SAID HEATER APPLIES HEAT TO SAID RESPONSIVE MEANS WHEN SAID SWITCH OPERATES FOR ANTICIPATION PURPOSES, SAID HEATER COMPRISING A FIRST PORTION AND A SECOND PORTION CONNECTED IN SERIES, SAID FIRST PORTION BEING A LOW RANGE RESISTANCE PORTION, AN ADJUSTABLE CONNECTION FOR SELECTING THE AMOUNT OF SAID HEATER TO BE ENERGIZED, SAID FIRST PORTION HAVING A LARGE PHYSICAL DIMENSION INCREASING THE SURFACE AREA PER UNIT LENGTH TO INCREASE THE HEAT DISSIPATION WHEREBY UPON A PREDETERMINED HIGH CURRENT PASSING THROUGH SAID FIRST PORTION, THE TEMPERATURE OF SAID FIRST PORTION WILL BE LIMITED TO A PREDETERMINED VALUE BY THE LOSS OF HEAT FROM SAID SUPPORT MEMBER.
