  • Brain twister
    Patent number: 6994343
    Abstract: A brain twister includes an inner structure and a plurality of movable elements and a plurality of stationary elements arranged on the inner structure. The movable elements are arranged to orbit about the stationary elements. At least three of the moveable elements and one of the stationary elements form a group. The moveable elements in the group are arranged to move around the stationary element of the group. The brain twister includes a plurality of groups. Each moveable element forms a part of at least two of the groups.
    Type: Grant

  • Anisotropic permanent magnets
    Patent number: 4536230
    Abstract: A permanent magnet made of a rigid material, said magnet having, within its entire body or in a part thereof, an anisotropic magnetic structure wherein the axes of easy magnetization in the elementary magnet regions have a convergent orientation in the environment of at least one of magnet poles. The value of magnetic induction to be delivered by the magnet of the invention to an air gap, or other part of magnetic circuit is raised relative to conventional anisotropic permanent magnets made of the same materials.
