  • Passive levitation in alternating magnetic fields
    Patent number: 7795770
    Abstract: Stable levitation of an object in an alternating magnetic field can be achieved by eliminating coupling between the rotational and translational forces acting on the object. Stable levitation can also be achieved by varying the coupling between the rotational and translational forces acting on the object, while maintaining one or more of the rotational and translational forces steady in time.
    Type: Grant
    Filed: March 25, 2009
    Date of Patent: September 14, 2010
    Assignee: Sandia Corporation
    Inventors: Louis Romero, Todd Christenson, Eugene A. Aronson

  • Method and apparatus for controlling electroslag remelting
    Patent number: 5331661
    Abstract: Method and apparatus for controlling electrode immersion depth in an electroslag remelting furnace. The phase difference of the alternating current circuit established in the furnace is calculated in real time and employed to more accurately control immersion depth than possible with voltage-swing systems.
