Abstract: An induction heating apparatus that can operate at current frequencies of greater than 60 Hz and at least 1 kW. The induction heating apparatus includes a high frequency power supply, a superconductive induction coil, and a fluid cooling system. A fluid cooling system is designed to cause a cooling fluid to flow at least partially about and/or through the superconductive induction coil.

Abstract: An apparatus to feed elongated metallic workpieces to a manufacturing process including a storage hopper configured to hold a plurality of workpieces that are randomly oriented and a movement device having a workpiece support that is automatically engageable with a workpiece.

Abstract: An induction heater is provided for heating electrically conducting workpieces. The heater comprises an induction coil having a number of turns including long straight conductors wherein a major portion of the long straight conductors are secured to a concrete support beam. The conductors and the support beam vibrate together in response to electromagnetic field forces generated during operation of the heater. The coil is caused to vibrate with the coil support beam by a hard adhesive which bonds the support beam and the coil or by tension members which hold the coil tightly to the support beam.
