Abstract

1,052,855. Induction heating coils. ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE CHARLEROI. Aug. 23, 1965 [Aug. 26, 1964], No. 36129/65. Heading H5H. Articles are induction heated to a uniform temperature in a device comprising a watercooled main coil 1, Fig. 1 (not shown), having at each end a water-cooled supplementary coaxial coil 5 connected in parallel with part of coil 1 and located in such a field of coil 1 that the no load voltage induced by the field of coil 1 in coil 5 is greater than the voltage applied across coil 5. This arrangement compensates the weakening of the magnetic field at the ends of coil 1. Ends 4, 6 of coils 1, 5 are connected at 3 and selected terminals 10, 11, 12 on coil 5 and 8, 9 on coil 1 are connected by a bar 13. Three main coils may be connected to a 3-phase transformer.
