Temperature-responsive current controlling inductor device

Claim 1

AN IMPROVED TEMPERATURE-RESPONSIVE CURRENT CONTROLLING INDUCTOR DEVICE COMPRISING IN COMBINATION, A MAGNETIC CORE ELEMENT, AN INDUCTIVE ELECTRICAL WINDING SUBSTANTIALLY SURROUNDING SAID CORE ELEMENT, SAID CORE ELEMENT COMPRISING A PORTION FORMED OF A SUBSTANCE HAVING A GIVEN CRYSTALLINE STRUCTURE AND A NORMAL CURIE POINT WITH USUAL CURIE POINT BEHAVIOR, SAID SUBSTANCE ALSO DISPLAYING, IN ADDITION CURIE POINT BEHAVIOR, AN ABRUPT CHANGE IN INTERNAL ENERGY AND IN SATURATION MAGNETIZATION ACCOMPANYING AND RELATED TO A FIRST-ORDER TRANSITION FROM ONE SOLID STATE PHASE TO A SECOND SOLID STATE PHASE, SAID CRYSTALLINE STRUCTURE REMAINING UNCHANGED DURING SUCH A TRANSITION AND DURING SUCH CHANGES IN INTERNAL ENERGY AND MAGNETIZATION, SAID SUBSTANCE DISPLAYING ITS ABRUPT CHANGE AS AN INCREASAE IN INTERNAL ENERGY AND IN SATURATION MAGNETIZATION IN RESPONSE TO INCREASED HEAT INPUT AT A GIVEN CONSTANT TEMPERATURE POINT BETWEEN ABSOLUTE ZERO AND ITS CURIE POINT, THE INDUCTANCE OF SAID DEVICE INCREASING SHARPLY TO CONTROL CURRENT IN SAID WINDING WHEN SAID DEVICE IS SUBJECTED TO AN INCREASED HEAT INPUT WHICH CAUSES SAID SUBSTANCE TO PASS THROUGH ITS SAID FIRST ORDER TRANSITION.
