Patent DE-3828203-A1 (DE)
Title: Suspension and guide unit
Inventor: ALBERSINGER GEORG
IPC: B60G11/27
Filed: 1988-08-19
Abstract: The unit is a compact combination of spring and guide elements with numerous possible applications. Elements integrated into an air-spring bellows (1) are configured in such a way that they guarantee a limited freedom of motion in the direction of springing but can accept guiding forces in a direction radial thereto. By virtue of the flexible or ball-joint-like construction of the guide elements (3), a spherical pivoting or compensating motion between the sprung and the unsprung part of the unit is possible in addition. The suspension and guide unit serves to provide sprung support and guidance for elements in vehicles and machines, e.g. wheel suspension systems in vehicle construction. <IMAGE>

Title: Batch-type continuous-flow washing machine
Inventor: SCHWARZE FRIEDRICH
IPC: D06F31/00
Filed: 1989-02-06
Abstract: In known batch-type continuous-flow washing machines, sealing arrangements or annular sliding bearings are used for separating the various washing baths. According to the invention, the disadvantages occurring thereby - complicated sealing arrangement, increased demands on the coaxiality of the inner and outer drums, non-adjustable seals, exchange possible only with the inner drum lifted out - are to be eliminated. In a batch-type continuous-flow washing machine, there are proposed, between the washing drum (1) and wash tub (3), seals which on the one hand each surround a concentric disc (13) of the washing drum (1) axially sealingly in a tongue-like manner by means of two lips (20, 21) and on the other hand rest sealingly in a V-shaped guide groove of the wash tub (3) on two points (7, 8). A manual or automatic adjusting device is present. Batch-type continuous-flow washing machine in a double-drum version over all or part of its length. <IMAGE>
