Abstract: The invention relates to an orthopaedic socket for bearing on and for receiving a limb stump or a limb, having at least one socket wall (2), a proximal access opening (3), a distal end (4) and at least one fastening device (5) which is arranged for fastening at least one distal orthopaedic component (6) to the socket (1), wherein at least one stiffening element (40) is arranged or formed on or in the socket wall (2), said stiffening element being assigned an adjustment device (30) and by means of which a stiffness of the socket wall (2) is reversibly variable at least in certain regions.

Abstract: A method for depositing nickel-metal layers for colouring surfaces, and a bath for depositing such a layer. This is made possible by depositing a nickel-metal layer from a bath for the electroless deposition of nickel which contains at least one further metal compound, a voltage being additionally applied enable the metal of the metal compound to be incorporated while forming a nickel-metal layer.

Abstract: The invention relates to a method for producing a noble metal/metal layer, which has particularly advantageous tribological properties, comprising the following steps: providing a bath for the currentless deposition of a metal layer, which additionally contains at least one type of noble metal ions; introducing a substrate into the bath; and applying a voltage.
