Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
112 words
A TEMPERATURE CONTROL CIRCUIT INCLUDING IN COMBINATION: (A) TRANSDUCER MEANS RESPONSE TO A CHANGE IN TEMPERATURE FOR PRODUCING A CORRESPONDING FIRST CHANGE IN VOLTAGE; (B) ELECTRONIC CIRCUIT MEANS RESPONSIVE TO SAID FIRST VOLTAGE CHANGE FOR ENERGIZING A LOAD; AND (C) MEANS CONNECTED BETWEEN SAID ELECTRONIC CIRCUIT MEANS AND SAID LOAD FOR PRODUCING A SECOND CHANGE IN VOLTAGE AT SAID ELECTRONIC CIRCUIT MEANS AIDING SAID FIRST VOLTAGE CHANGE AND SUFFICIENT TO MAINTAIN SAID ELECTRONIC CIRCUIT MEANS CONDUCTING AND SUFFICIENT TO MAINTAIN SAID LOAD ENERGIZED UNTIL SAID TRANSDUCER MEANS PRODUCES A THIRD VOLTAGE CHANGE AT SAID ELECTRONIC CIRCUIT MEANS WHICH WILL COUNTERACT SAID FIRST AND SECOND VOLTAGE CHANGES AND DE-ENERGIZE SAID ELECTRONIC CIRCUIT MEANS.
