Total Claims: 2
Claim 1
Independent Claim
161 words
AN INDUCTIVE WINDING COMPRISING, A GENERALLY CYLINDRICAL COIL HAVING A PLURALITY OF TURNS OF CONDUCTIVE SHEET METERIAL WOUND TO FORM A SINGLE ELECTRICAL TURN PER LAYER AND HAVING A FIRST END AND A SECOND END, AND A FIRST LEAD CONNECTED TO SAID FIRST END AND A SECOND LEAD CONNECTED TO SAID SECOND END WHEREBY AN AXIALLY NONUNIFORM AXIAL CURRENT FLOW REGION IS ESTABLISHED NEAR EACH SAID ENDS, AT LEAST SAID FIRST LEAD HAVING A FIRST PART EXTENDING FORM THE TOP OF SAID COIL AND A SECOND PART EXTENDING FROM THE BOTTOM OF SAID COIL WHEREBY THE AXIAL CURRENT FLOW ALONG SAID FIRST END IS DIVIDED BETWEEN SAID PARTS AND THE STRAY LOSSES IN THE REGION OF SAID FIRST END ARE REDUCED, ONE OF SAID PARTS BEING POSITIONED TO EXTEND AXIALLY ALONG SAID SECOND COIL END TO OPPOSE THE MAGNETIC FIELD ASSOCIATED WITH AXIAL CURRENT FLOW ALONG SAID SECOND END TO REDUCE THE STRAY LOSSES IN THE REGION OF SAID SECOND END.
