Abstract: A variable width transverse flux electric inductor has a fixed powered coil section and associated box-like moveable passive coil sections that electromagnetically couple with magnetic flux generated by current flowing through the fixed powered section. The passive coil sections can be transversely moved across the workpiece to accommodate induction heating of workpieces having different widths or track movement of the workpiece. Alternatively the fixed powered coil section and associated moveable coil sections may be connected to each other through flexible connections, sliding contacts or other means, such as clamps, so that an electrical connection can be maintained between both in any relative position.

Abstract: A transverse flux electric induction heating apparatus is provided with a pair of transverse flux inductor assemblies where the inductor in each one of the pair of assemblies is formed from a pair of continuous flexible cables disposed within movable roll channels in roll assemblies that are used to adjust the transverse length of the inductor across the edge-to-edge transverse of a workpiece moving between the inductor in each one of the pair of assemblies and/or to adjust the pole pitch between transverse inductor lengths of each inductor in the pair of assemblies.

Abstract: A rectangular sheet heating inductor or a multi-turn inductor is provided for induction heat treatment of a strip or slab material that may require a change in the interior opening of the inductor to allow an abnormal region of the material to pass through the interior opening and/or to allow a change in a dimension of the inductor to achieve impedance load matching with a material having variable electromagnetic properties such as a multiphase steel.

Abstract: An electric induction rail heater is provided for selectively adjusting the heated temperatures in a rail's head, web and foot sections after fabrication of the rail. Alternatively, the rail heater can be used for heating the opposing ends of two rails that are to be welded together. The electric induction rail heater is a transverse flux electric inductor that can be provided with or without magnetic cores.
