Patent DE-4039064-A1 (DE)
Inventor: MOSER HANS
IPC: A61F2/48
Filed: 1990-12-07
Abstract: This device consists of an adaptor 1 which is to be arranged between two endoprosthesis parts, and of a pump 9 which can be actuated manually and is provided with or connected to a liquid reservoir 8. The adaptor 1 consists of two interlocking, displaceably mounted sleeves 3, 4, which are closed at the head end and one of which has in its interior a piston 11 which can be moved longitudinally in the interior of the other sleeve 4, and enclose together with the inner head end of the other sleeve 4 a liquid-tight and liquid-filled pressure chamber 7. The pressure chamber 7 is connected via a pressure line 10 to the pump 9. Pump, pressure line and pressure chamber form a self-contained hydraulic system. Liquid is pumped into the pressure chamber 7 by actuating the pump, after which the outer sleeve executes a movement in the expansion direction X. It is possible to provide as securing system toothed strips 12 and 13 on the inner sleeve 4, which cooperate with toothed strips of locking jaws 18 and 17, respectively, in such a way that the toothed strips are locked when there is no pressure in the pressure chamber 7. The locking can be abolished when pressure is applied to the pressure chamber 7 so that the movement in the expansion direction X of the sleeve 3 is possible. The device can be implanted as a unit. Expansion of the adaptor to be performed postoperatively is possible without invasive intervention. <IMAGE>

Patent DE-4219321-A1 (DE)
Inventor: DRAENERT KLAUS PROF DR MED
IPC: C04B41/45
Filed: 1992-06-12
Abstract: The invention concerns a material suitable for use as a bone substitute or as a material for anchoring endoprosthesis components in place, plus a method of producing the material. The material described contains a polymer and/or copolymer plus filler particles which are at least partly enclosed in the polymer and/or copolymer. The material is granulate or fibrous in nature and is produced by mixing the polymer powder and filler particles to give a homogeneous mixture which is then heated and extruded through a nozzle, or the polymer powder is heated and the filler injected hot upstream of or directly into the extrusion nozzle. Following hardening, the mixture is ground to give a granulate material or the polymer fibres obtained are cut to the required length.
Patent DE-4220639-A1 (DE)
Inventor: JEROMIN LUTZ DR
IPC: C11B13/00
Filed: 1992-06-24
Abstract: In the process proposed, the raw oil or fat is mixed at elevated temperature with acid and water and allowed to react so that the impurities pass into the aqueous phase. The mixture is then separated into purified oil and acid water. The acid water is concentrated by ultrafiltration and the permeate fed back to the initial stage of the process in which the raw oil or fat is mixed with acid and water. The oil and fat constituents emulsified with the aqueous phase are thus recovered and the quantity of waste water produced is considerably reduced.
