Method of making a magnetic core

Claim 1

THE METHOD OF MAKING A SUBSTANTIALLY SCRAPLESS LOW LOSS LAMINATED MAGNETIC CORE FROM A SHEET OF GRAIN ORIENTED MATERIAL COMPRISING THE STEPS OF CUTTING A PAIR OF E-SHAPED LAMINATIONS FROM SAID SHEET OFF MATERIAL, UTILIZING THE MATERIAL REMOVED FROM THE SHEET IN FORMING THE LEGS OF SAID E-SHAPED LAMINATIONS TO PROVIDE A PAIR OF I-SHAPED LAMINATIONS, SAID I-SHAPED LAMINATIONS HAVING A WIDTH GREATER THAN THE WIDTH OF THE BACK OF SAID E-SHAPED LAMINATIONS BY A RATIO OF AT LEAST 1.2, THE LEGS OF SAID E-SHAPED LAMINATIONS AND THE LONGITUDINAL DIMENSION OF SAID ISHAPED LAMINATIONS BEING FORMED SUBSTANTIALLY PARALLEL WITH THE GRAIN ORIENTATION OF SAID MATERIAL, THE BACKS OF SAID E-SHAPED LAMINATIONS BEING FORMED SUBSTANTIALLY TRANSVERSE TO SAID GRAIN ORIENTATION, EACH LAYER OF LAMINATINS OF SAID MAGNETIC CORE HAVING LAN E-SHAPED LAMINATION WITH ITS LEG PORTIONS DISPOSED TO ABUT AGAINST AN I-SHAPED LAMINATION, THE BACK PORTION OF SAID E-SHAPED LAMINATION BEING DISPOSED AT OPPOSITE ENDS OF SAID MAGNETIC CORE IN ALTERNATE LAYERS OF SAID LAMINATIONS, SAID ISHAPED LAMINATIONS OVERLAPPING THE BACKS OF SAID E-SHAPED LAMINATIONS, SAID I-SHAPED LAMINATIONS HAVING RECESSED SURFACES AT THE END THEREOF FOR LINDEXING THE BACK PORTIONS OF THE E-SHAPED LAMINATIONS DURING THE ASSEMBLY OF SAID CORE.
