Philip S Carter, John F Krumme: Alternating current electrically resistive heating element having intrinsic temperature control. Iris Associates, C Michael Zimmerman, March 17, 1981: US04256945 (393 worldwide citation)

The heating element consists of a substrate or core of a non-magnetic material having high thermal and electrical conductivity, clad with a surface layer of a ferromagnetic material of relatively low electrical conductivity. When the heating element is energized by a source of high frequency alterna ...
