Title: Scale for length measuring devices
Inventor: MUELLER HELMUT
IPC: G01B5/00
Filed: 1988-07-15
Abstract: For the purpose of accurately determining the temperature of the scale, detectors (sensors) in the form, for example, of vapour deposited metal film resistors (6) are integrated directly into the scale (1). The measured temperature values are used for computer correction of changes in the length of the scale (1) which are caused by thermal expansion. <IMAGE>

Title: Process for the utilisation of steel works filter dust and similar material
Inventor: LOTTERMOSER MANFRED DIPL PHYS
IPC: C21B13/08
Filed: 1988-09-20
Abstract: Iron oxides and materials containing nonferrous heavy metal compounds, in particular wastes of metallurgical processes, such as steel works filter dusts, blast furnace dusts, red mud and the like, are treated with reducing gases at glowing temperatures. Over the time-temperature course, nonferrous heavy metal granules form which are separated off from the residual material. The iron-containing residual material is supplied to the iron or steel production, if appropriate together with steel scrap.

Title: Water-channelling hose reel
Inventor: BOECKLE HARALD
IPC: B65H75/44
Filed: 1988-10-14
Abstract: A water-channelling hose reel having a reel spindle serving as a water supply line, in the case of which the connection to the water valve connected to the water-pipe network takes places via a flexible hose piece. In the case of the novel hose reel, a considerable reduction in production costs and a greater degree of user friendliness are achieved in that the reel spindle is designed in a number of parts. Said spindle comprises an L-shaped, first pipe piece which is rotatably mounted in the first reel disc. A second, T-shaped pipe piece which can rotate with respect to the first pipe piece is pushed onto the first pipe piece by means of its horizontal portion. Said second pipe piece is connected to a third pipe piece which is fastened on the second reel disc. Second and third pipe pieces are fixedly connected to the reel, whereas the first pipe piece can rotate with respect to the reel. The hose is fastened on the vertical portion of the second pipe piece. Corresponding to a further development of the invention, it is provided that the vertical portion of the second pipe piece is designed in two parts. This embodiment makes it possible for the connection piece for the hose to rotate through 180@ as required in each case.

Title: Cushion support for a motor vehicle seat
Inventor: WOERZ HERBERT DIPL ING
IPC: A47C31/02
Filed: 1988-10-19
Abstract: In a cushion support for a motor vehicle seat with at least one cushion layer and a laminated-on nettle-cloth base as well as, projecting away therefrom, a fastening for fixing the cushion support on a basic cushion body, the uppermost cushion layer being provided on the user side with a covering, it is proposed, to achieve a marked pipe character, with as much freedom as possible with regard to coverings to be used, to make the first cushion layer provided with the nettle-cloth base from a relatively hard foam, this layer being provided with grooves at the spacing of the pipe width. The grooves are covered by a second cushion layer consisting of soft foam and a third cushion layer designed as a fleece, in each case with oversize. A cover consisting of an elastic warp-knitted material follows on the third cushion layer, which cover, during the sewing process which takes place on the edge side and in the groove bottom of the grooves of the first cushion layer, binds in the cushion layers loosely, forming markedly stepped seam paths for the cover still to be put on.
Patent DE-3835601-A1 (DE)
Inventor: WENDT HANS JOACHIM DIPL ING
IPC: G02F1/13357
Filed: 1988-10-19
Abstract: In a digital computer with multiprocessor arrangement, each processor is a highly integrated computer chip on a semiconductor basis connected to the other processors in the arrangement, which are of same design, via a highly meshed management system composed of meshes and nodes for transmitting digital signals. Peripheral devices such as keyboards, memories, monitors, image sensors, speech analysis units, speech synthesis units as well as transmitters are connected to the computer. According to the invention, the management system is a beam waveguide network. Each node (26) is associated with a processor (11) to which it is coupled via an optical emitter (21) and an optical receiver (22). The new types of chip interconnection which result and hence the high packing density of the chips and large number of cross-connections obtained are particularly advantageous. The computer network has a high functional density and the computer and peripherals are unaffected by electromagnetic influences.

Title: Keyboard
Inventor: SCHMIDT PETER DIPL ING
IPC: G06F21/83
Filed: 1988-10-19
Abstract: In a keyboard for input of data into a computer system, with a key pad, to which a decoding and analysis unit, which is connected to the computer system via a transmission unit, is connected in series, a switch (3) is connected between the analysis unit (2) and the transmission unit (4). When the keyboard and/or the computer system (7) is/are switched on, the switch (3) is in the blocking state. It is controllable by a code recognition unit (6), which receives keyboard signals, which represent a password and are supplied by the key pad to the analysis unit (2), and compares them with password data which are stored in a memory unit (5). The code recognition unit (6) only sets the switch (3) to conducting, and enables data transmission between the analysis unit (2) and the transmission unit (4), if the password which is entered via the key pad (1) agrees with the stored password. <IMAGE>

Title: Input selection switch using two-way analogue switch
Inventor: KOH YOUNG-SAN
IPC: H03K17/62
Filed: 1989-05-18
Abstract: An input selection circuit is described which uses a number of two-way analogue switches (Sa1, Sb1, Sn1; Sa2, Sb2, Sn2), which is designed so that means of feedback between the inputs of two-way analogue switching means (40) and the output of an amplifier (50) are provided, this input selection circuit being distinguished in that directional power deviations of the two-way switches (Sa1, Sb1, Sn1; Sa2, Sb2, Sn2) provided in the two-way switching means (40) can be reduced when transmitting signals. Signal distortion originating from directional power deviation can therefore be decreased in the case of the input selection switch according to the invention. <IMAGE>

Title: Circulating system for foam reagents - in which layout with control and non-return valves and regulator produces polyurethane foam and prevents steep pressure drops
Inventor: MICHAEL VOLKER
IPC: B29B7/74
Filed: 1990-02-03
Abstract: A circulation block for mixing heads, and particularly for those with parallel nozzles in equipment for the prodn. of polyurethane foam, has a nozzle with valve needle and seating in which the needle has an annular surface exposed to the pressurised reagent and opened under pressure; a  hydraulic control device has a valve in two flowlines, the one being on the closed and the other on the open side of the mixing head; according to the position of this valve either the closed side is subject to the operating pressure or the open side is subjected to opening pressure; the line to the open side is also connected to an annular space in the block which enables the nozzle needle to be closed. This particular flow line has a non-return valve open to the annular space; a regulator is in the line between this valve and the block so that a set pressure is applied to the annular space and held there; another line for pressure release can connect to the line between the regulator valve and non-return valve; when the nozzle needle opens under the pressure of the reagent and when the pressure in the annular space exceeds the set level this pressure release line allows the pressure to drop to the set valve again. ADVANTAGE - The system produces precise operational control. In particular it prevents the occurrence of any excessively steep pressure drop.
