Title: Water-swellable layers on substrates or in the layer sandwich as a support for photosensitive systems
Inventor: KOSCHE HORST H DR RER NAT DIPL
IPC: B41N3/03
Filed: 1983-10-01
Abstract: The invention relates to water-insoluble layers or a firmly adhering layer sandwich whose surface layer is capable of absorbing aqueous solutions of water vapour by swelling. If moisture is applied in a metered manner, the surface layer remains nonadhesive. The layer sandwich has a self-supporting structure or is deposited on substrates, for example polyester films or water-sensitive, naturally transparent cellulose papers, for the barrier layers which are contained in the layer sandwich as a protection against aqueous solutions. In order to meet the requirements, the hydrophilic surface layer which absorbs water and dries out again is of a structure which is materially inhomogeneous per se. It is penetrated by a finely distributed, structure-forming matrix composed of a water-insoluble high-molecular-weight substance. Hydrophilic substances which have a reduced molecular size and which are not water-soluble but are solvatable are then incorporated in this sponge-like network. They contain free carbonyl and/or hydroxyl groups accumulated to a limit value. The hydrophilic layer may be composed of a homogeneous material class, for example polymeric vinyl esters. The individual functional substances are then distinguished only by their molecular size and by the degree of esterification of their hydroxyl and/or carbonyl groups. Matrix and barrier layers form a solid sandwich with one another. Layers formed in this manner ... Original abstract incomplete.

Title: Solid bowl screw centrifuge with sludge discharge nozzles
Inventor: HOLZER MANFRED
IPC: B04B1/20
Filed: 1983-12-15
Abstract: In solid bowl screw centrifuges with radial sludge discharge nozzles in the bowl and with at least one control member which revolves in the centrifuge relative to the nozzles and effects a periodic opening and closing of the nozzles, a difficulty is that the nozzle cross-sections only permit the discharge of a nearly unvarying quantity of solids per unit time. A change of the solids discharge quantity can only be effected by stopping the machine and changing the nozzles. However, this is expensive in labour, time and costs. According to the invention, however, these difficulties and disadvantages are eliminated in that the control member is a rotor (8) acting as a lock member and constructed with receiving and transport areas (20,20') for sludge in the form of recesses (9) or chambers (34) on the circumferential region (26). <IMAGE>

Title: Guide frame for sliding roofs of motor vehicles or tiltable sliding roofs
Inventor: SCHEFFEL BERND DIPL ING
IPC: B60J7/057
Filed: 1984-05-14
Abstract: A guide frame (1, 1', 2) for sliding roofs of motor vehicles or tiltable sliding roofs is equipped with its own drive pinions (7, 8) for each cable (3, 4). These drive pinions are arranged in the two parallel legs (1, 1') of the guide frame. Therefore, the lengths of the cables (3, 4) which are stressed cannot experience any deflection and therefore no additional friction forces. The driving forces are lower than in known designs. In contrast with known designs, the central part (2) of the guide frame does not serve to guide the cables in a compression-resistant fashion. Therefore, the central part (2) can be designed essentially according to production criteria. <IMAGE>

Title: Shock wave generator having a freely movable plate
Inventor: REICHENBERGER HELMUT DR RER NA
IPC: G10K9/12
Filed: 1985-02-25
Abstract: A freely movable plate (9) is placed in front of a flat coil (3). An insulating film (7) is located between the two. An electromagnetic field which repels the plate (9) from the flat coil (3) is generated by discharging a capacitor (1) via a trip element (5) into the flat coil (3). The plate (9) accelerated in this way impacts against a target body (13) at a prescribed distance, suddenly releasing its energy to it. The energy propogates as a sound wave through the target body (13) and passes at the exit face (19) thereof into a coupling medium (20), e.g. into water. The advantage of the shock wave generator is a short, steep rise in the generated sound wave in conjunction with a short period of the first half wave (shock wave). The shock wave generator is intended for use in medical technology in the destruction of kidney stones. <IMAGE>
