Abstract: A spring induction heater assembly is shown and described. The device has a quench tank incorporated into the design. A motor and drive mechanism provide rotation of a spring about one axis from a first position used for loading, to a second position for heat treatment with an induction coil and a third position where the spring is released dropped into a quench tank. Another rotational system is operational to rotate the spring on a spindle in the second or horizontal position while the spring is located between at least two legs of an induction coil. The induction coil provides even heating to the spring coils thereby providing desired changes to the material properties. The quench tank can have an automated system to remove the springs from the quench tank.

Abstract: A material conversion apparatus includes: (a) a housing, (b) a chamber for treating the material disposed within the housing, (c) an induction coil surrounding the chamber and (d) means for exhausting or evacuating the treated content of the chamber.

Abstract: A rotary heating apparatus to heat evenly symmetrical and/or non-symmetrical workpieces. A rotatable shaft holds directly or indirectly one or more workpieces. The shaft has a first major central elongated axis. An induction coil providing a magnetic field and has a second major central elongated axis. The coil is fabricated with an open space in a side of the coil The open space is configured and dimensioned to accommodate the passage of the shaft while avoiding contact between the shaft and any portion of the coil. The shaft is arranged so that said first major axis is positioned perpendicular to the second major central elongated axis.

Abstract: A processing line material clear out devices and methods are disclosed. The device is particularly useful for clearing metal billets from induction heating units, but may be used for many other processes having sequentially ordered materials traveling down a conveyor or other processing line. In one example of the invention, a reciprocating push rod rack is used to sequentially deposit and remove at least two push rods used to abut and clear the downstream billets. A push rod advance device is used to interlink independent, sequential push rods positioned on the billet track. On clearing of the billets, the push rods are retracted, removed from the billet track and stored on the push rod rack for ready use.
