  • Patent number: 10030719
    Abstract: A clutch (1) with an inner ring (2) arranged about an axis of rotation (d) and an outer ring (3) arranged coaxially in reference thereto, as well as an elastic clamping ring (4) arranged between them and radially limited thereby, with the inner ring (2) and the clamping ring (4) resting on each other via a ramp device (9), arranged bi-directionally effective in the circumferential direction, and clamping segments (13) pointing radially outwardly and arranged distributed in the circumferential direction, form in case of a radial displacement of the clamping ring (4) forming with the outer ring (3) a clamping connection in at least one circumferential direction. In a further aspect, a radial displacement of the clamping ring (4) is provided via a ramp device (12) effective in the axial direction, switched by an axial displacement of the inner ring (2) in reference to the clamping ring (4).

  • Patent number: 9592847
    Abstract: A steering column arrangement has a sliding sleeve and a universal joint yoke, which has a receiving section in which the sliding sleeve is included at least in sections and coaxially. The covering outer surface of the sliding sleeve and the covering inner surface of the receiving section have molded components for the positive connection. A torsion damper element is arranged between the sliding sleeve and the receiving section of the universal joint yoke. This is an annular arrangement, including an inner carrier ring, an outer carrier ring and an elastomer ring arranged between them. The inner carrier ring and outer carrier ring are elastic in a radial direction and rigid in an axial direction.

  • Patent number: 9065055
    Abstract: The present invention relates to a method for preparing doped organic semiconductor materials as well as a formulation which may be utilized in that method. The doped organic semiconductor materials are prepared by preparing a solution or suspension containing at least one dopant precursor, at least one organic material to be doped, and a solvent. The solution or suspension is then applied onto a substrate. After removing the solvent, the dopant precursor is converted into a dopant by application of activation energy. The dopant precursor, which is a dimer, oligomer, polymer, dispiro compound, or polycycle, is cleaved by the application of activation energy.
