Instrument for inducing heat into an elongated object whose temperature is to be measured
First Claim
1. An instrument for inducing heat into an elongated object whose temperature is to be measured, comprising heating means formed to be fastened to and at least partially enclose a portion of the object whose temperature is to be measured, power terminal means fastened to said heating means, a power supply connected to said power terminal means for supplying heating current to said terminal means and to said heating means, said heating means having means to contact said object for permitting conduction of heat directly to and along a predetermined portion of said object thereby heating said heating means and said object, and thermocouple means for sensing the temperature of said object, said thermocouple means being located adjacent said object and being connected to means for providing an indication of the measured temperature of said object.
