Abstract

574,914. Electric induction heating. STANDARD TELEPHONES & CABLES, Ltd. Feb. 18, 1944, No. 3057. Convention date, Feb. 25, 1943. [Class 39 (iii)] In the high frequency induction heating of workpieces, e.g., for surface hardening, inequalities in the depth of heating due to counter magneto-motive forces in the workpiece are prevented b) the use of a shield S of high electric conductivity sur. rounding the inductor A. A slot 4 is provided to prevent a closed circuit, and the shield is earthed at 7 and connected to the central part of the in ducing coil A at 8. The frequency is of the order of 5,000,000 cycles per second.
