Patents by Inventor Robert T. Ruffini

Robert T. Ruffini has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • 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.
    Type: Grant
    Filed: February 15, 1995
    Date of Patent: December 24, 1996
    Assignee: Fluxtrol Manufacturing, Inc.
    Inventors: Robert S. Ruffini, Robert J. Madeira, Robert T. Ruffini
