Patent DE-3819303-A1 (DE)
Title: Flat rolling mill
Inventor: DRUSCHKE WERNER
IPC: B21B27/05
Filed: 1988-06-03
Abstract: The invention relates to a flat rolling mill with work rolls which are supported - if required via intermediate rolls - on back-up rolls and in which at least one of the work rolls or at least one of the work rolls and/or the intermediate rolls has a ground-on camber and in which, if required, the work roll or the work rolls and/or the intermediate rolls can be displaced axially to change the cross-section of the rolling gap. In order to avoid areas of compression on the back-up rolls or intermediate rolls when using rolls with a ground-on camber, it is proposed that the rolls with the ground-on camber should be supported by back-up rolls and/or intermediate rolls with a hydraulically expandable roll shell (H). <IMAGE>

Title: Gyroscopic devices with communicating liquid-filled vessels for the time-delayed generation of moments
Inventor: CHRISTOPH PETER DR RER NAT
IPC: G01C19/34
Filed: 1988-07-29
Abstract: For functional control in gyroscopic devices, particularly in gyroscopic compasses, communicating vessels are used in which viscous fluid, particularly oil, can flow to and fro in the case of an inclination and thus generates torques on the gyroscopic system which exhibit a low-pass effect due to the viscosity of the fluid. With very low level differences, however, small disturbances which narrow down the functional control quality occur in the level compensation due to adhesive and surface-tension influences on the vessel walls. According to the invention, the required regularity of the flow of the fluid down to the smallest differences in level is achieved by the fact that the vessel walls are completely wetted by lining with a thin layer of absorbent porous material which always remains wetted by the action of capillarity, no matter what the level of the fluid in the vessels is. The annular vessel used as oil-filled damping vessel in the two-gyro compass requires high accuracy in the regularity of the oil equalisation, especially for small level differences, if the commercially available two-gyro compass is to be developed into a high-precision compass, in that the calculable course indication errors due to manoeuvres are continuously corrected with the aid of a computer which is fed with the travelling speed values supplied by the travel measuring system.

Patent DE-3831055-A1 (DE)
Title: Method for the digital coding of information of one, two or more channels and/or reducing the frequency of the alternating coding current or currents and transmission thereof
Inventor: DIRR JOSEF DIPL ING
IPC: H04L27/24
Filed: 1988-09-12
Abstract: The frequency-division or time-division multiplex multiple utilisation of current paths has previously been known. However, these methods require considerable expenditure and need a wide bandwidth. In the present invention, this is avoided by the fact that the code elements of the various channels, which are arranged synchronously or quasi synchronously, are ordered in parallel and are all combined to form one codeword and are transmitted.

Title: Piece of seating furniture which can be converted into a bed
Inventor: PLETZING KARL HEINZ
IPC: A47C17/207
Filed: 1988-12-08
Abstract: A piece of seating furniture which can be converted into a bed possesses a back cushion 11 and an auxiliary cushion 10 which, in the sitting position, is situated approximately upright behind the back cushion 11 and, in the lying position, serves to increase the lying area. The auxiliary cushion 10 is, on the one hand, articulated via a hinge 9 on a trolley 2 capable of being extended from the furniture frame 1 and is, on the other hand, guided by means of rollers 15 and 16 in lateral guides 17. In order to keep the space requirement for the auxiliary cushion 10 during its displacement as small as possible, the auxiliary cushion 10 has two articulatedly interconnected parts 12 and 13, so that the auxiliary cushion 10 adapts to the course of the guides 17 during its movement therein. <IMAGE>

Patent DE-3844094-A1 (DE)
Inventor: SCHWANEKAMP WOLFGANG
IPC: E04G11/06
Filed: 1988-12-28
Abstract: In a known aligning clamp, the two claws (3, 4) are situated at a virtually invariable distance from one another which is adapted to the thickness of the outer crossbeams of shuttering-panel frames, so that the aligning clamp (1) is only suitable for holding together and mutually aligning directly abutting shuttering panels (14, 18). In contrast, the new aligning clamp is to be able to hold together and mutually align shuttering panels even when compensating pieces (16) are situated between the shuttering panels. In the new aligning clamp, one of the two claws (4) is mounted such that it is displaceable in the axial direction of the crossmember of the aligning clamp and fixable to this crossmember in a variable position. This design of the aligning clamp makes it possible roughly to preset the basic distance between the two claws, intended for drawing together and clamping shuttering panels, in accordance with the section to be bridged in each case, before the aligning clamp is attached to the shuttering panels to be drawn together and is tightened into the gripping position. <IMAGE>

Title: Drawing die and method for the use thereof
Inventor: WEINHOLD HARRI DR ING
IPC: B21C3/02
Filed: 1989-02-02
Abstract: The invention relates to the field of metallurgy and concerns drawing dies for the single- or multi-stage drawing of strand-shaped metallic material to be formed. The invention is based on a drawing die, in which the drawing bore has an entrance and an exit funnel, as well as a drawing hole which consists of a cylindrical guide part and a drawing cone. According to the invention, the drawing hole and/or the entrance funnel has, at least in part, an unpolished rough surface with an arithmetic average peak-to-valley height of Ra >/= 0.15  mu m which inhibits the lubricant flow. The drawing die is used in particular as a single drawing die or as an entrance or working drawing die for pressure dies.
Patent DE-3905230-A1 (DE)
Title: Ink-ribbon cartridge
Inventor: WAGNER MARTIN
IPC: B41J32/02
Filed: 1989-02-21
Abstract: The invention relates to an ink-ribbon cartridge for packed endless ink ribbons, in which returning and packing the endless ink ribbon takes place by a transporting device which is arranged at the entry aperture into a supply space and consists of rollers which are mounted with a fixed axial spacing and between which the endless ink ribbon runs. Since it is hardly possible to place an endless ink ribbon, for example, between two rollers in the form of meshing pinions, one of the rollers may only be moved into its final position after the endless ink ribbon has been inserted. In a known solution, the roller has to be provided at the packing station and then mounted completely. This is undesirable due to the operating sequence and the risk of soiling at this point. The invention avoids these disadvantages in that it provides a roller which is premounted in a bearing block which can be fitted on to a bearing pin inside the housing with spacing from the upper roller and, when the ink ribbon has been inserted, can be pivoted by a short movement into a catch position which is also the final operating position.

Title: Gas generator for an airbag
Inventor: BENDER RICHARD DIPL CHEM DR
IPC: B01J7/00
Filed: 1989-03-04
Abstract: In order to prevent the filling of an airbag from being too abrupt after initiation, at least one tubular pressurised container (2'') or a region of a tubular pressurised container (2) in the vicinity of the central body (1) has its reaction kinetics lowered somewhat by the fact that the thickness of the mouldings (3'') is increased and/or the diameter of the gas passage aperture (4', 4'') and/or of the ignition channel (5'') and/or the surface of the outlet bores (7) are reduced in the casing surface of the tubular pressurised container (2). This ensures that the quantity of gas generated is reduced initially and that the reaction speed increases with some delay, although the final condition of the inflated airbag is not unfavourably affected by this measure. <IMAGE>
