A system for attaching a phenolic panel to a metal part includes a phenolic laminate panel having (i) a phenolic panel, (ii) a ferromagnetic susceptor bonded at an inner side of the phenolic panel via higher melting point adhesive and (iii) a non-magnetic shield having an outer side bonded at an inner side of the ferromagnetic susceptor via higher melting point adhesive. A lower melting point adhesive is applied at an inner side of the non-magnetic shield opposite from the outer side of the non-magnetic shield. With the phenolic laminate panel disposed at a metal part, an electromagnetic field is generated at the phenolic laminate panel to heat the phenolic laminate panel to a temperature greater than the melting point of the lower melting point adhesive and less than the melting point of the higher melting point adhesive to bond the phenolic laminate panel to the metal part.

A system and a method for separating and recycling magnets made from rare earth elements from an article of manufacture used an alignment device to property position the rare earth magnet for processing. Once proper alignment is made, a separating device removes the magnet and a portion of the article. A heating device demagnetizes the magnets and vibration causes the magnets to separate from the portion of the article. Electromagnets remove the portion of the article and the rare earth magnets pass through for reclamation.

The transverse flux induction heating device allows an alternating magnetic field to intersect the sheet face of a conductive sheet which is conveyed in one direction, thereby inductively heating the conductive sheet. The transverse flux induction heating device includes a heating coil disposed such that a coil face faces the sheet face of the conductive sheet; a core around which the heating coil is coiled; and a shielding plate formed of a conductor and disposed between the core and a side end portion in a direction perpendicular to the conveyance direction of the conductive sheet, wherein the shielding plate has a protruded portion, and the side surface of the protruded portion represents a closed loop when viewed from a direction perpendicular to the coil face.

Discrete workpieces move through a longitudinally-oriented through-gap in an open-box rectangular ferromagnetic material. A transverse magnetic flux established in the through-gap inductively heats the discrete workpieces moving through the longitudinally-oriented through-gap. A longitudinal axis of the workpiece or the planar surface of a planarly-oriented workpiece is oriented either parallel to, or perpendicular to, the transverse magnetic flux to heat treat the workpiece.
