Gerhard Martinek 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).

  • Contoured-field magnets
    Patent number: 10600539
    Abstract: Apparatus and methods for manufacturing magnets, and magnets, having magnetically oriented grains, and apparatus including such magnets. The field of a permanent magnet may be shaped by applying an external field to the material from which the magnet is made in such a way as to magnetize different regions of the material in different directions. The apparatus may include, and the methods may involve, a metal-powder press that may press metal powder in the presence of a magnetic field. The press may compress the powder in an axial direction. The field may have flux lines that are transverse to the axial direction. The field may have flux lines that are along the axial direction.
    Type: Grant
    Filed: March 3, 2016
    Date of Patent: March 24, 2020
    Assignee: Magnetic Technologies AG
    Inventors: Gerhard Martinek, Urs Wyss
