Abstract: The invention relates to an apparatus for unravel-ling wire ropes (3), which are made up of a complex of different materials, having a peeling device (1) with an opening (5), through which a core (9) of the wire rope (3) passes along a through-feed axis (D) and a through-feed direction (Z), while an outer portion (10) is separated, said peeling device (1) comprising a mandrel (4) through which the opening (5) passes axially, with at least one rotatable cutting wheel (12) being provided next to the mandrel (4), which wheel has on the circumference thereof at least one blade (13) and the axis of rotation (R) of which wheel is substantially transverse to the through-feed axis (D), characterized in that a cut-ting profile (6) of the blade (13) or a common cutting profile (6) of the blades (13) is concave in form.

Abstract: Cartilage tissue and implants comprising tissue are produced in vitro starting from cells having the ability to form an extracellular cartilage matrix. Such cells are brought into a cell space (1) and are left in this cell space for producing an extracellular cartilage matrix. The cells are brought into the cell space to have a cell density of ca. 5×107 to 109 cells per cm3 of cell space. The cell space (1) is at least partly separated from a culture medium space (2) surrounding the cell space by means of a semi-permeable wall (3) or by an open-pore wall acting as convection barrier. The open-pore wall can be designed as a plate (7) made of a bone substitute material and constituting the bottom of the cell space (1). The cells settle on such a plate (7) and the cartilage tissue growing in the cell space (1).

Abstract: A process for the production of prostheses wherein endogenic tissue material is substantially mechanically comminuted and, if necessary, additionally enzymatically digested to tissue particles, whose sizes fall within very narrow limits. A preshaped carrier material is treated with the resultant suspension. In the case of a porous carrier material the suspension is filtered through the material, whereas with less or non-porous carrier material the suspension is applied to the material surface by centrifuging. Unlike the case of corresponding prior art processes, as a result of this improvement, the process according to the invention can be performed very rapidly, i.e., directly during the operation and in a closed system.
