Mark James Le Feuvre 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: 8315680
    Abstract: In a cold superconducting joint, a joint cup is provided. Lengths of superconducting filaments are placed in the joint cup. A superconducting material fills the joint cup in contact with the superconducting filaments and in thermal and mechanical contact with a pipe carrying a cryogen. The pipe extends into the joint cup and the superconducting material extends around the pipe within the joint cup.
    Type: Grant
    Filed: January 25, 2012
    Date of Patent: November 20, 2012
    Assignee: Siemens PLC

  • Patent number: 7692426
    Abstract: In an arrangement with a basic field magnet and with a gradient coil of a magnetic resonance apparatus, the basic field magnet includes superconducting coils that are arranged in a reservoir with liquid helium for cooling. The helium reservoir is surrounded by a further reservoir, designated as an outer vacuum chamber. A vacuum exists between the outer vacuum chamber and the helium reservoir. A cryoshield is arranged between the outer vacuum chamber and the helium reservoir. The gradient coil is arranged in the inner chamber of the basic field magnet. The outer vacuum chamber has an additional coating with a high electrical conductivity.

  • Publication number: 20090179033
    Abstract: An opening device of plastics material, which is suitable for closing and re-closing of a metal can end, for example. The opening device has two distinct parts: a base plate (10) and a tab (1), which are joined together by an integral rivet (14, 15). The opening device is used to close an aperture in the metal panel of a can end by fitting the base plate to the underside of the panel and connecting this to the tab on the top of the panel. A sliding action by pulling or retaining the tab actuates movement of the base plate for opening and reclosing of the closure panel.
