  • Magnetic Ground Clamp
    Publication number: 20070034619
    Abstract: A magnetic ground (or earth) clamp in which the current carrying electrode is electrically insulated from the housing to prevent electric arcing between the electrode and the housing or between the housing and the surface to which it is clamped.
    Type: Application
    Filed: August 9, 2006
    Publication date: February 15, 2007
    Inventor: Ian Heard
  • Rollable Magnetic Clamp
    Publication number: 20070034757
    Abstract: A magnetic clamping device which uses rollers or wheels to create an air-gap between the clamping edges and a ferromagnetic work-piece, thereby reducing friction so that the clamp is able to be rolled or easily moved upon the surface or surfaces to which it is clamped.
    Type: Application

  • Apparatus for lifting of ferromagnetic metal sheets
    Publication number: 20050269827
    Abstract: A relatively lightweight permanent magnetic system employing as integral components on a frame, plate or table, a plurality of shallow field magnetic devices specifically to grip, lift and carry a thin ferromagnetic metal sheet and a means to discharge the retained ferromagnetic metal sheet at will by taking advantage of the propensity of such steel sheet to bend under pressure.
