Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
75 words
THE METHOD OF MAKING A MAGNETIC CORE LOOP COMPRISING THE STEPS OF FEEDING A CONTINUOUS STRIP OF MAGNETIC MATERIAL TOWARD A ROTATING CORE FORM, CUTTING THE STRIP INTO INDIVIDUAL STRIP SEGMENTS, MOMENTARILY VARYING THE RELATIVE SPEED OF EACH CUT-OFF SEGMENT AND THE STRIP AFTER EACH CUT TO EFFECT LAPPING OF THE LEADING END OF THE STRIP AND EACH SEGMENT AS THE LATTER IS CUT OFF, AND WINDING SAID SEGMENTS ONE AFTER ANOTHER ON SAID FORM.
Claim 2

Claim 3
Independent Claim
58 words
THE METHOD OF MAKING A MAGNETIC CORE LOOP ADAPTED TO BE ANNEALED AND THEN DISASSEMBLED AND REASSEMBLED AROUND A WINDING LEG OF A PREFORMED CONDUCTIVE WINDING, SAID METHOD COMPRISING CONTINUOUSLY FEEDING A CONTINUOUS STRIP OF MAGNETIC MATERIAL TOWARD A ROTATING CORE FORM, SENSING THE COMPLETION OF EACH CYCLE OF ROTATION OF THE CORE FORM THROUGH A PREDETERMINED ANGLE
