    摘要： An induction heating device for surface treating the teeth (11) of a mechanical part on which each tooth (111) has a projecting tip (111s) and a tooth root linking the tooth to an adjacent tooth, wherein an in duction coil (12, 12') is spaced from the tooth tips and powered by at least one high-frequency current source. The coil consists of a set of conductive segments (24, 24') individually orthogonal to the generatrix (d, d') of the teeth, located above respective tooth tips and interconnected via connecting segments (25, 25').

    摘要： A formable composite magnetic flux concentrator material is composed of about 65% to 90% ferromagnetic material, such as iron powder, and about 35% to 10% binder, the binder being a mixture of an epoxy and one or more catalysts. The concentrator material is provided in a formable state as a putty-like body which can be worked into any desired shape dictated by the configuration of the induction heating coil used in a particular application. In one form, the density of the concentrator material is increased by application of vibration, compression and vacuum to de-air the material and to reduce voids therein. In another form, the iron powder comprises spherical-shaped particles and non-spherical shaped powders chosen in a ratio to maximize the density of material available.

    摘要： An induction heater for heating a portion of a load comprises a side entry coil driven by a source of alternating current, with a flux concentrator located at the coil opening. The coil produces a magnetic field in the region occupied by the flux concentrator and the heated portion of the load. The flux concentrator extends along the opening of the coil and is fabricated of high permeability, low loss material, such as nickel-zinc ferrite, so as to enhance the uniformity of the magnetic field generated within the coil. In the preferred application, heating produces a complete fluid block in a cable section within the coil without overheating or damaging the cable.

    摘要： The product (11) is in relative motion in the direction (12) of its axis with respect to at least one magnetic inductor (10, 10'). The metallurgical product (11) is subjected to at least two magnetic fluxes (19, 19') having non-parallel directions which are transverse with respect to the longitudinal direction of the product (11). The heating device may advantageously consist of two C-shaped magnetic yokes (14, 14') spaced apart and angularly offset along the axial direction (12) of advance of the product (11).
