Abstract: A spray quench system is provided with one or more spray quench rings that eject a controlled volume of quenchant spray onto a workpiece passing through the quench rings. Supply of the quenchant to the quench rings is coordinated with control of the quench rings to selectively change the pressure, quenchant spray exit velocity from the quench rings, flow rate or pattern of the quenchant spray onto the workpiece depending upon mass cooling requirements as the workpiece passes through the quench rings.

Abstract: A solenoidal induction coil with dynamically variable coil geometry is provided for inductively welding or heating continuous or discontinuous workpieces passing through the solenoidal induction coil in a process line. The coil geometry can change, for example, as the outer dimension of the workpiece passing through the solenoidal induction coil changes or as non-continuous workpieces pass through the solenoidal induction coil in an induction heating or welding process line.

Abstract: A solid state switching circuit utilizes a transformer in series with the circuit's switching device by which energy initially stored in the primary of the transformer is recovered in resonant circuitry connected to the secondary of the transformer for transfer of the energy to the load when the switching device is not conducting.

Abstract: High frequency electrical heating apparatus in which metal parts (10) are heated as they are advanced, either for annealing or forge welding purposes, and in which the electrical heating current is supplied by a solid state D.C. to A.C. inverter (2-5, 8) through a load matching and frequency control circuit (13) which maintains the desired load current and current frequency with changes in the load impedance caused by the metal parts (10) as they are advanced.

Abstract: A method and apparatus in which edge portions of metal parts (1), the edge portions being disposed with opposed surfaces (3, 4), are heated by high frequency electrical currents as the edge portions are advanced and brought together at a weld point (5). The electrical currents are induced in the edge portions in advance of the weld point (5) by two induction coils (6, 7), one at one side of the metal parts (1) and the other at the other side of the metal parts (1), disposed and energized from a high frequency electrical source so that the electrical currents at the opposed surfaces flow in opposite directions at any given time and the currents induced by one coil (6) add to the currents induced by the other coil (7).
