  • Heat treating of metallurgic article with varying aspect ratios
    Patent number: 6166360
    Abstract: This invention provides methods for rapidly heating a metal part of varying thickness. In general, the invention provides methods comprising heating the thicker section(s) of the part by induction heating and the thinner section(s) by resistance heating. Induction and resistance heating both quickly heat metals and because each is easily controlled individually, the part can be uniformly heated for hardening and tempering.

  • High performance induction melting coil
    Patent number: 5588019
    Abstract: An improved induction melting coil apparatus encapsulated with homogeneous inserts for controlling the direction of inductor flux density is disclosed. The inserts are relatively thick and rigid members which provide a low reluctance path within which the magnetic field travels while inhibiting inductive coupling of the magnetic field with surrounding auxiliary components. The inserts can be easily formed or machined into any desired shape for effectively encapsulating virtually any type of coreless induction melting coil.
