  • Magnetorheological polishing devices and methods
    Patent number: 6503414
    Abstract: A method of polishing an object is disclosed. In one embodiment, the method comprises the steps of creating a polishing zone within a magnetorheological fluid; determining the characteristics of the contact between the object and the polishing zone necessary to polish the object; controlling the consistency of the fluid in the polishing zone; bringing the object into contact with the polishing zone of the fluid; and moving at least one of said object and said fluid with respect to the other. Also disclosed is a polishing device. In one embodiment, the device comprises a magnetorheological fluid, a means for inducing a magnetic field, and a means for displacing the object to be polished or the means for inducing a magnetic field relative to one another.
    Type: Grant
    Filed: July 3, 1996
    Date of Patent: January 7, 2003
    Assignee: Byelocorp Scientific, Inc.
    Inventors: William I Kordonsky, Igor V Prokhorov, Sergei R Gorodkin, Gennadii R Gorodkin, Leonid K Gleb, Bronislav E Kashevsky

  • Magnetorheological valve and devices incorporating magnetorheological elements
    Patent number: 5452745
    Abstract: A valve used to control the flow of a magnetorheological fluid, in which the mechanical properties of the magnetorheological fluid are varied by applying a magnetic field, is described. The valve can comprise a magnetoconducting body with a magnetic core that houses an induction coil winding, and an hydraulic channel located between the outside of the core and the inside of the body connected to a fluid inlet port and an outlet port, in which magnetorheological fluid flows from the inlet port through the hydraulic line to the outlet port. Devices employing magnetorheological valves are also described.
