  • Orientation ring with bearings
    Patent number: 4223961
    Abstract: An orientation bearing ring for resisting radial loads, axial loads, and inclined moments. The ring includes first and second races each of unitary construction, opposed thrust faces of the races have roller thrust bearings between them with the axes of the bearings perpendicular to the axis of the ring. An additional row of bearings is disposed in opposed bearing tracks in the respective races, these bearings engaging their tracks at an oblique angle to the axis of the ring.

  • Movable electrical contact device
    Patent number: 4209214
    Abstract: A plurality of conductive rings are arranged projecting relatively to a fixed component. Such ring comprises two thin conductive circles separated by an electrically insulating material. Blades fixed to pins make sliding contact with the outer and inner circles. The blades are advantageously staggered relatively to one another. It is thus possible to obtain a very compact electrical contact device between two concentric members capable of undergoing relative rotation.
