Claims

1. A GALVANIC ACTION DEVICE COMPRISING:

A GALVANIC CELL WHICH DEVELOPS A CORROSION CURRENT HAVING A MAGNITUDE DEPENDENT UPON THE TEMPERATURE OF AN ELECTROLYTE IN WHICH SAID CELL IS IMMERSED;

A BIMETALLIC DISC WHICH EXPANDS OR CONTRACTS IN RESPONSE TO TEMPERATURE CHANGES FOR DETECTING CHANGES IN SAID TEMPERATURE;

AND A CARBON RESISTIVE ELEMENT ELECTRICALLY CONNECTED IN SERIES WITH THE ELECTRODES OF SAID GALVANIC CELL AND CAPABLE OF VARYING IN RESISTANCE BY CONTRACTING OR EXPANDING IN RESPONSE TO EXPANSIONS OR CONTRACTIONS OF SAID BIMETALLIC DISC FOR VARYING THE RESISTANCE THROUGH WHICH SAID CORROSION CURRENT FLOW TO COMPENSATE FOR CHANGES IN SAID CURRENT WHICH TEND TO BE DEVELOPED BY CHANGES IN SAID TEMPERATURE.
