  • Patent number: 8535314
    Abstract: In order to configure, in such a way as to be capable of being employed in a simple and secure manner and produced cost-effectively, a surgical connecting element for fixing adjacently arranged bone plates, comprising a first bearing element, a second bearing element and a coupling element, by means of which the first and second bearing element can be coupled to each other in such a way that bone plates lying between the first and second bearing element can be fixed, it is proposed that the second bearing element and the coupling element be so designed and adapted to each other that, by relative movement between the coupling element and the second bearing element transversely to a clamping direction, the bone plates are fixable between the first and the second bearing element.

  • Publication number: 20120218728
    Abstract: A method for patterning a layer stack with at least one ceramic layer includes providing the ceramic layer, which has at least one plated-through hole. An electrically conductive layer is applied above the ceramic layer, such that the electrically conductive layer is electrically coupled to the at least one plated-through hole. A further layer is deposited onto the electrically conductive layer in the region of the at least one plated-through hole, wherein the further layer includes nickel. The electrically conductive layer is removed outside the region of the at least one plated-through hole. A carrier device patterned in this way can be electrically and mechanically coupled to an electronic component.

  • Patent number: 8201831
    Abstract: A sliding element comprises at least one surface for sliding contact with a running face, wherein a wear layer and a run-in layer made from carbon are applied to the surface, and is characterized in that the run-in layer comprises hydrogen and nanocrystalline carbide phases. In a method for manufacturing a sliding element, the run-in layer is applied by means of a PVD process. A sliding system has an above-described sliding element and a body having a running face. A coating for a sliding element comprises a wear layer which can be applied to the upper side of the sliding element, and a run-in layer which is configured as a carbon layer, and is characterized in that the run-in layer comprises hydrogen and nanocrystalline carbide phases.
