Abstract: A bearing device for motor vehicle shafts is described, in particular for motor vehicle steering shafts. The bearing device is provided for torque transmission between an inner shaft and the hollow shaft surrounded by the inner shaft. The inner shaft and the hollow shaft each have opposing bearing grooves, in which rolling elements are received. At least one positive locking cam in radial direction is provided. A safety contour is assigned to the positive locking cam, the safety contour comprising two engagement positions for the positive locking cam. In the case of unoccupied bearing grooves the positive locking cam is rotationally movable along the safety contour between the engagement points during a torque transmission, in a manner that a defined relative movement between the inner shaft and the hollow shaft is possible, which generates both tactile feedback and acoustic feedback. Furthermore, an automotive shaft assembly is described.

Abstract: The invention relates to an implant with a shank which is insertible into a bone cavity, which shank is made of a plastic, in particular of a bioincompatible plastic, and defines at least one bone contact face, wherein the bone contact face is provided or coated with a first biocompatible bone contact layer or bears a biocompatible bone contact layer, wherein the shank of the implant is intended to be anchored in the bone cavity without bone cement and wherein the first bone contact layer is formed entirely closed.

Abstract: The invention relates to a joint implant part of a joint endoprosthesis. The joint implant part comprises at least one first volume region, at least one second volume region and at least one third volume region. The at least one first volume region defines a bone contact surface region with at least one bone contact surface. The at least one second volume region defines a joint surface region with at least one joint surface. The at least one third volume region comprises neither a bone contact surface nor a joint surface. A modulus of elasticity in the at least one first and/or in the at least one second and/or in the at least one third volume region changes continuously or substantially continuously or discontinuously in at least one spatial direction.

Abstract: A method for increasing the retention of a scale inhibitor within a hydrocarbon producing system is provided. The method includes, the steps of: (i) pre-flushing the system with a liquid; (ii) treating the system with a scale inhibitor; and (iii) over-flushing the system with a composition comprising an ionic polymer and a liquid carrier. The concentration of the ionic polymer in the composition is 5 to 50% wt.

Abstract: A bone replacement material having reinforcing elements and a modelable mass which is curable on contact with water or an aqueous liquid. as well as a process for producing a bone replacement material, to a further bone replacement material and to medical kits for treatment of bone defects.
