Roger D. Huczko 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).

  • Automatic flashover protection for locomotive traction motors
    Patent number: 5245495
    Abstract: Flashover protection is provided for a locomotive propulsion system including a plurality of d-c traction motors each having a commutator subject to flashovers, a traction alternator having armature and field windings and a rotor driven by a prime mover, a controllable source of excitation current connected to the alternator field, and means including an electric power rectifier for connecting the alternator to the motor commutators. It comprises means for producing a fault signal whenever a flashover occurs in any motor, a solid-state controllable electric valve connected between the excitation current source and the alternator field and having alternative conducting and non-conducting states, and means for changing the valve from conducting to non-conducting states in response to a fault signal being produced, whereupon the magnitude of excitation current in the alternator field is rapidly reduced toward zero and the alternator's output current is correspondingly decreased whenever a flashover occurs.
    Type: Grant
    Filed: November 30, 1992
    Date of Patent: September 14, 1993
    Assignee: General Electric Company
    Inventors: Ronald B. Bailey, Herbert J. Brown, Myron L. Smith, Edgar T. Balch, Roger D. Huczko, Joseph A. Laukaitis
