Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
138 words
A TEMPERATURE COMPENSATED GAUGING APPARATUS IN WHICH AN OBJECT TO BE MEASURED PASSES THROUGH A RADIATION PATH, SAID APPARATUS COMPRISING AN EMITTER FOR PRODUCING PENETRATIVE RADIATION, A RECEIVER IN SAID PATH FOR CONVERTING SAID RADIATION INTO A DIRECT VOLTAGE PROPORTIONAL THERETO, A SINGLE PAIR OF OUTPUT TERMINALS FOR SAID DIRECT VOLTAGE, A LOAD RESISTOR AND A TEMPERATURE COMPENSATING CIRCUIT SERIES CONNECTED ACROSS SAID TERMINALS, SAID CIRCUIT COMPRISING A STANDARD REFERENCE DIRECT VOLTAGE SOURCE AND A RESISTANCE ELEMENT DISPOSED CLOSE TO SAID PATH TO BE INFLUENCED BY THE TEMPERATURE PREVAILING IN SAID PATH AND SERVING TO DEVELOP A COMPENSATING DIRECT VOLTAGE AS A FUNCTION OF CHANGES OF SAID TEMPERATURE IN THE PATH, SAID COMPENSATING VOLTAGE BEING IMPRESSED IN BACKING RELATIONSHIP ON SAID TERMINALS, WHEREBY THE OUTPUT OF THE GAUGING APPARATUS IS INDEPENDENT FROM TEMPERATURE VARIATIONS IN THE RADIATION PATH.
Claim 2
Dependent Claim
138 words
