Abstract
832,795. Heating by induction. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 14, 1956 [Dec. 19, 1955], No. 38283/56. Class 39(3) A method of inductively heating workpieces prevents overheating of certain portions of the workpieces. In Fig. 1, overheating of the corners 5 of a slotted steel shaft 1 is prevented by directing the path 11 of the high frequency current away from the corners, the path for the current being completed through copper members 6, 7, applied to the shaft. The heating current is induced by a coil 8. In heating for surface hardening the edge 12 of a sewing machine spool 13, Fig. 4, the heating current is directed away from the pointed end 16 and flows through circular copper members 15, 19; a coil 22 induces the heating current. In a further application, Fig. 5, halves of a knife handle 23 to be soldered together are clamped between two members 27, 28 such that end portions 25 of the handle are not in the direct path of the current induced by a flat coil 29. U.S.A. Specification 2,673,921 is referred to.
