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: Electric induction heating of the edges of a slab comprising an electrically conductive, non-ferrous material is achieved with a transverse flux induction coil that comprises a pair of coil sections with the slab passing between the coil sections. The coil sections extend transversely beyond the opposing edges of the slab. Magnetic flux concentrators are positioned around regions of the coil sections that are above and below the slab. An electrically conductive compensator is inserted between each of the two opposing extended ends of the coils sections in the vicinity of an edge of the slab. Alternatively only one of the edges of the slab may be inductively heated.

Abstract: A fluid latent heat absorption electric induction heater is provided for raising the temperature of a fluid supplied to a fluid-driven turbine in a turbine-driven electric power generation system. The fluid latent heat absorption electric induction heater alternatively transfers heat to the fluid by induced susceptor heating, or a combination of inductor Joule heating and induced susceptor heating. The fluid may be water-steam for powering a steam-driven turbine or another fluid used in a phase change system for driving a fluid-driven turbine in a turbine-driven electric power generation system.

Abstract: A method is provided for making the longitudinal temperature distribution of the bulbous end of a longitudinally oriented workpiece, such as a rail's head, generally uniform when the head has a non-uniform longitudinal temperature distribution. A combination of crown and skirt electric inductors is used to achieve the generally uniform temperature distribution by modulating the magnetic field intensity produced by current flow through one or more of the combination of crown and skirt inductors as required for the non-uniformly heated regions of the rail's head.

Abstract: The fundamental frequency power factor is improved and a practical reduction in significant harmonic current is made in electrical power systems where the power to the load is controlled by a non-linear device, such as a saturable reactor, by using series inductive-capacitive filters to filter the significant harmonic current to act as a shunt for harmonic current in conjunction with a supply line inductive reactance. The resonant frequency of each filter is less than the frequency of the harmonic current and the impedance of each said inductivecapacitive filter is a net inductive reactance. The capacitive element of the filter provides a leading power factor component to compensate for the lagging power factor component imposed on the supply system by the non-linear control device.

Abstract: Apparatus for controlling power and for compensating for a low power factor due to a relatively large varying inductive load. A number of branches having an inverse parallel connected pair of thyristors and a capacitor connected in series are connected in parallel. These parallel branches are connected in series between an alternating current source and the load. At least one thyristor of one of the inverse parallel connected pairs of thyristors is gated on at some time during each half cycle of the alternating current supply voltage in order to control the power flow to the load. One thyristor of one or more of the inverse parallel pairs of thyristors is gated on at appropriate times during each half cycle in order to place one or more of the capacitors, which are in parallel with each other, in series between the source and the load.

Abstract: An induction coil furnace system includes at least an active induction coil and a passive induction coil surrounding a furnace volume. The active induction coil is connected to an AC power supply, while the passive induction coil is connected in parallel with one or more capacitors forming an L-C tank circuit. The connections to the AC power supply and the one or more capacitors are optionally an interchangeable connection, such that the active coil can become the passive coil upon disconnection of the AC power supply and connection of the one or more capacitors. Likewise, the passive coil can become the active coil upon disconnection of the one or more capacitors and connection of the AC power supply. The active coil is selectively electrically connected to the passive coil via a separable electrical connection, whereupon separation, the active coil and the passive coil are electrically isolated.

Abstract: A method is provided for life cycle wear monitoring of a consumable refractory in an electric induction furnace used for heating and melting materials by accumulating laser imaging data of the refractory's inner surface periodically over the refractory's life cycle while the furnace is utilized in a foundry environment and processing the accumulated imaging data for comparative analysis with previous laser imaging data of the refractory's inner surface.
