Claims

1. IN A SURFACE TEMPERATURE MEASURING DEVICE, THE COMBINATION COMPRISING TEMPERATURE SENSING MEANS INCLUDING A PART CONTACTABLE WITH A SURFACE THE TRUE TEMPERATURE OF WHICH IS TO BE MEASURED AND ARRANGED TO GENERATE A MEASURABLE SIGNAL RESPONSIVE TO THE TEMPERATURE SENSED;

AND MEANS, INCLUDING THERMOCOUPLE MEANS AND HEATER MEANS BOTH IN CONDUCTIVE HEAT EXCHANGE RELATION WITH EACH OTHER THROUGH DIRECT CONTACTING SOLID BODIES AND SIMILARLY WITH SAID TEMPERATURE SENSING MEANS, ARRANGED TO HEAT SAID TEMPERATURE SENSING MEANS BY THERMAL CONDUCTION SO AS TO ELIMINATE NET HEAT FLOW BETWEEN SAID TEMPERATURE SENSING MEANS AND SAID SURFACE WHEN THE LATTER IS CONTACTED BY SAID PART.
