Title: Drive arrangement
Inventor: WIEDEMANN BERND DIPL ING
IPC: F04C29/00
Filed: 1989-04-06
Abstract: A description is given of a drive arrangement for a mass driven eccentrically in a fixed housing, in particular for the disc-shaped rotor (3) of a scroll-type displacement machine (1) (G-Lader) which has a first eccentric device (7), arranged on a drive shaft (5), for driving the mass (3) and a second eccentric device (21), arranged at a distance from the first eccentric device, for guiding the mass on a translational path of motion. In addition, means are provided for the forced adjustment of the mass (3) beyond the extreme positions of the path of motion. In the invention, these means are to consist of respective magnet poles (18, 19) mounted on the mass (3) and on the housing (2). In operation, these poles run past one another and are arranged in such a way that, in the extreme positions of the path of motion, there arises from the repulsion of like poles an adjusting force which adjusts the mass in the predetermined driving direction. <IMAGE>

Title: Graded upholstery for mattress - with blocks and layers having differing modulus of elasticity
Inventor: HOH DIETER
IPC: B32B7/022
Filed: 1989-09-28
Abstract: Upholstery material, esp. for mattresses, is made of two elastic non-metallic materials which can absorb forces and energy and have widely differing elasticity moduli. A first material which absorbs an essential part of the energy is divided into individual blocks (1,2,3) and has a much greater modulus of elasticity, but only a limited horizontal extension. The second material (4) has a lower modulus of elasticity but is deformable over a much wider area. The horizontal dimension of the blocks is less than the total thickness (under 10cm) and they are sepd. from each other by intervals. The ideal material for the material of the blocks is rubber coco and for the material (4) is latex foam or polyurethane (PU). ADVANTAGE - This eliminates the ``hammock'' effect of mattresses with steel springs and gives more sleeping comfort.
Patent DE-4000107-A1 (DE)
Inventor: PUESCHMANN MANFRED
IPC: D01H1/08
Filed: 1990-01-04
Abstract: Fibre material (9, 11) is fed to a pair of centrifugal spindles (6, 7) from separate delivery points (4, 5) of a drawing frame (1). After each centrifugal spindle (6, 7) is filled with partially twisted thread material, the supply of fibre material (9, 11) is interrupted until the start of the next delivery phase and the material is transferred to a spooling arrangement (8) and is given a final twist. During the course of the working process, fibre material is simultaneously fed to both centrifugal spindles. Between the spooling phase and the delivery phase for each centrifugal spindle, there is a preparatory phase during the course of which the centrifugal spindles are alternatively cleaned and/or prepared for the next delivery phase. <IMAGE>

Title: Connecting digital communication network to analogue network - starting time generator on each digit from subscriber to starting exchange of digital network
Inventor: THULLEN RAINER PAUL DIPL ING
IPC: H04Q3/47
Filed: 1990-06-05
Abstract: The connection between a digital telecommunications network with a central code system and an analogue telecommunications network with a signalling system is carried out without selection end and start sign. Each subscriber transmits a digit to the original exchange of the digital network to start a time generator. On the time generator run, the characteristic signal of the code system is transmitted to a destination exchange, forming the transition to the analogue network. On the characteristic reception in the destination exchange, a selection end sign in the code system is transmitted to the original exchange, followed by a start sign of the destination exchange. USE/ADVANTAGE - Telecommunications control systems. Establishment of connection between two networks not affected even if the analogue network offers special service using analogue signalling without dial codes.

Inventor: JIRKA KARL
IPC: H02G9/06
Filed: 1991-03-28
Abstract: For the watertight and gastight fixing of cable assemblies in closed or also split cable channels, a sealing member is proposed which consists essentially of an integral supporting disc and an integral pressure disc, both being equipped with a retaining ring which can be latched in, between which a sealing disc is arranged which is provided with weak points and consists of a suitable elastomer.
