Title: Cushion for supporting the neck region
Inventor: KOCH WILHELM PROF DR MED
IPC: A47G9/10
Filed: 1983-06-04
Abstract: Cushions for supporting the head and neck regions of a reclining person have the disadvantage that they only permit people whose neck and head region is shaped in a specific manner to rest in a relaxed position. There is therefore a need to develop a cushion which guarantees complete relaxation in such a way that it provides support, even to people with different neck and head shapes, which guarantees a relaxed position of the sensitive cervical vertebrae. This is achieved with the cushion according to the invention in that it has two cores (1, 2) of fabrics of different compressibility extending over the width of the cushion and resting against one another. <IMAGE>

Title: Torque-loaded covered roller
Inventor: SCHUBERT WALTER DIPL ING
IPC: B22D11/128
Filed: 1983-07-08
Abstract: In torque-loaded covered rollers with a cover shrunk onto a core and liquid-cooled by the core there is a danger which increases with duration of use that the frictionally transmitted driving forces will become insufficient and consequently a pulling back of the cover on the core, combined with frictional wear, may take place on at least one of the two cooperating components. To improve the efficiency of torque-loaded covered rollers, at least one layer (8,9) exclusively produced by powder flame-spraying is applied to the peripheral surface (1') of the core in the region of the cover (4), except of course for the region of the coolant recesses (5), and hard components (10) are then embedded in the exterior of the layers (8) and additionally form a kind of positively locking connection with the cover (4). <IMAGE>

Title: Method for operating a two-phase permanent-magnet stepping motor with a unipolar drive
Inventor: KUCHENBECKER MANFRED DR ING
IPC: H02P8/32
Filed: 1983-09-29
Abstract: The invention relates to a method for operating a two-phase permanent-magnet stepping motor with a unipolar drive, whose aim is to connect the single-phase and two-phase operation to one another in such a manner that, when achieving high positioning accuracies, a high holding torque and torque are achieved as well as effective electrical damping. The invention is based on the object of developing a method for operating a two-phase permanent-magnet stepping motor in the case of which said motor is switched (while ensuring maximum voltage induction in the holding region) into the single-phase mode or two-phase mode at different times, as a function of its static and dynamic condition. According to the invention, for this purpose, in its holding position (in which current flows simultaneously through in each case three of the four winding halves of the two phase windings), the stepping motor is operated in the single-phase mode and, in the event of a movement through n steps, after a first half-step for further (n-1) steps is operated in the known two-phase mode, before it moves back into a holding position again after a second half-step. The use of the invention is particularly expedient for typing disc setting in printing or typing mechanisms, but is furthermore also possible in the case of multi-phase permanent-magnet stepping motors, by means of which it is intended to achieve high positioning accuracies. <IMAGE>

Title: Air filter for carburettor engines, especially in motor vehicles
Inventor: HEINERMANN HEINZ DIPL ING
IPC: B01D46/00
Filed: 1983-10-08
Abstract: An air filter for carburettor engines, especially in motor vehicles, has a flat pot-shaped filter housing arranged on the carburettor and a snorkel opening into the filter housing and serving as air intake, which snorkel is curved essentially in the plane formed by the filter housing. The snorkel is designed with an overall curve like a diffusor, has a cross section widening evenly from the air inlet towards the filter housing and is arranged on the side of the filter housing and opens tangentially or essentially tangentially into this.   Such an air filter is characterised firstly by improved air ducting in the snorkel, this air ducting being characterised in particular by the reduction of flow resistances. At the same time an air filter of this type permits a flatter engine compartment design because the curved snorkel laterally adjoining the air filter can be correspondingly led laterally around the transverse engine block to the radiator. This reduces the overall height inside the engine compartment to no more than the overall height of the engine block itself. Due to the said design of the air filter, including snorkel, and the flow characteristic of the feed air optimised by this, the flow resistances are considerably reduced. This results in the advantages of improved mixture distribution, a reduction in the noise generated, a more uniform ... Original abstract incomplete.

Title: Cable for a superconducting magnet
Inventor: JENTZSCH KLAUS
IPC: H01F6/06
Filed: 1983-12-01
Abstract: The invention relates to a cable for a superconducting magnet, in which a plurality of conductors are combined and arranged in a twisted manner, and which is wound on a coil core. The object on which the invention is based is for a cable of the initially mentioned type to be constructed in such a manner that it takes more account of the technical implementation capability of large superconducting magnetic coils. The solution is characterised in that the external cross-section of the cable is of hexagonal construction and is used for absorbing external forces. The hexagonal cable according to the invention accordingly differs from all known cables as a result of its cross-sectional shape. It can be wound directly on the coil former, as a result of which a high packing density can be achieved in the winding. The basic shape of the cable is always maintained, by varying the spanner width on the external hexagonal sheath.

Title: Method of preparing deposited earth material extracted from stretches of water
Inventor: KREEB HEINZ DR
IPC: E02B3/02
Filed: 1984-02-29
Abstract: To prepare deposited earth material extracted from stretches of water, in particular rivers, first of all separation is carried out between consolidated and less consolidated material and these different materials are fed to separate drying depots. In the process, the material present as a pulpy substance is fed into a drying basin, and after the top layer has dried this top layer is removed. This drying operation is repeated at intervals until the drying basin is empty. To avoid costly transport measures, it is proposed to store the pulpy substance on a slope at the edge of the drying basin and to allow this substance to flow automatically into the drying basin.

Title: Data-processing installation having computers which process the same data in two channels
Inventor: RADLOFF JUERGEN DIPL ING
IPC: G06F11/00
Filed: 1984-10-29
Abstract: In the case of a data-processing installation having computers (RR1, RR2) which process the same data in two channels, power is supplied to the two computers from a common DC supply source (UB), via a fuse (SG). Said fuse has a defined switching-off delay. Furthermore, two switching transistors (TR1, TR2) are connected to the fuse (SG) via in each case one resistor (R3, R4), each of which switching transistors (TR1, TR2) is provided with a switching code, which is sufficiently long in time, by means of one of the computers (RR1, RR2), in the event of a defect being confirmed. Said code leads to destruction of the fuse (SG) and hence to the two computers (RR1, RR2) being switched off. A test mode is provided, in which both switching transistors (TR1, TR2) have test signals supplied to them, which are short in comparison with the switching code, in such a manner that the fuse (SG) is not yet triggered, but a defined current flows via the one switching transistor or the other (TR1, TR2). The computers (RR1, RR2) receive an acknowledgement of this. <IMAGE>

Title: Process for producing motor vehicle lining parts
IPC: B29C44/14
Filed: 1985-03-04
Abstract: The invention relates to a process for producing lining parts for the interior of motor vehicles, such as dashboards, consoles, glove compartment covers, side-lining panels, by back-foaming a covering, which is preformed in a mould by heating and pressing, in a mould cavity, adapted to the final shape of the lining part, of a foam-supporting mould. Stiffening supporting parts are foamed-on or foamed-in. It is characteristic of the invention that, after the foam-supporting mould is closed, the mould cavity formed between the reverse side of the covering and one supporting mould half is sealed by pressing the covering along its edges and along at least one parting line onto the other supporting mould half by means of flexible tubular seals which are inserted into the supporting mould half lying against the face surface of the covering and can be inflated with controllable pressure. Furthermore, the mould cavity chambers, which are divided off with respect to one another by the flexible tubular seals, are filled from separate sources with different polyurethane foam systems. The foaming process is then accelerated in a manner known per se by heating the mould wall, and the gas occurring in the mould cavity during the foaming process is allowed to escape through the gaps which the tubular seals disposed in the edge region of the covering release under the pressure of the gas.
