Title: Hydraulic/mechanical twin clutch for improving the torque during acceleration processes with prime movers
Inventor: INGELHEIM PETER GRAF VON
IPC: F16H45/00
Filed: 1983-09-21
Abstract: The invention relates to a hydraulic/mechanical twin clutch for improving the torque during acceleration processes with prime movers.   In a hydraulic transmission, a pump (1), a hydraulic motor (5) and one or more valves (6, 14) are connected in such a way that, with the valves completely open, the pump delivery flow flows back to the inlet side of the pump or into the fluid reservoir (9) and thus no power is transmitted to the hydraulic motor (5). A mechanical clutch (15) connected in parallel can likewise be disengaged, with the result that no power flow from the prime mover to the driven machine takes place. With the valves (6, 14) of the hydraulic transmission closed and the shafts of the mechanical clutch running synchronously, the mechanical clutch can be connected up in such a way that power flows from the prime mover to the driven machine via the mechanical transmission with its high efficiency. The mechanical clutch can be disengaged in such a way that power flows from the prime mover to the driven machine via the hydraulic transmission, which can be controlled in such a way that the torque at the hydraulic motor can be increased at a predetermined speed of the hydraulic motor (5). Such a clutch can be used to increase the torque at the driven machine in the case of accelerations, while, in the case of unaccelerated power transmission, which, for example, in motor vehicles, accounts for the majority of power transmission, the high efficiency of a mechanical transmission ...

Title: Device and process for crucible-less zone-melting of a semiconductor crystal rod which, at its lower end, is provided with a fused-on seed crystal and which is supported perpendicularly to both ends
Inventor: KELLER WOLFGANG DR RER NAT
IPC: C30B13/32
Filed: 1983-10-21
Abstract: The invention relates to a device for crucible-less zone melting of a semiconductor crystal rod (2) which, at its lower end, is provided with a fused-on seed crystal (1). The rod end (3) containing the seed crystal (1) is braced by a structure comprising at least three supporting arms (4) co-rotating with the semiconductor crystal rod (2). Each supporting arm (4) comprises the pole shoes (5, 6) of an electromagnet (7) and at its upper end has an inclined plane (8) made from a non-magnetic material. Between the ends of the pole shoes (5, 6) and in the acute angle formed by the inclined plane (8) and the semiconductor crystal rod (2) there is a support disc (9) made of ferromagnetic material. If a pulsed direct current is applied to the electromagnet (7), the supporting disc (9) is slowly moved towards the semiconductor crystal rod (2). <IMAGE>

Title: Miniature artificial head for acoustic model tests
Inventor: BLAUERT JENS DR ING PROF
IPC: H04R5/027
Filed: 1984-03-27
Abstract: In acoustic model tests, in which model sound fields are intended to be used to generate auditory impressions as they occur in the corresponding original sound fields, there is a need for true-to-scale replicas of natural heads as a recording set up. This invention treats such artificial model heads. The simulation of the auricles of the original is performed by slice-wise scanning of the original auricles and a suitable reducing method. The invention further contains detailed solutions for the microphone arrangement in the head replica, and for the design of the replicas of the acoustic duct and their coupling to the microphones.

Filed: 1984-04-10
Abstract: Proposed for the measurement of forces and vibrations on antifriction bearings is a measuring instrument having a sensor which is formed by a bimorphous piezoelectric element serving to generate force-dependent signals. The piezoelectric element has two layers lying one on top of the other like a sandwich, and is accommodated in a protective sheath formed by a tube. Whereas the tube forms the earth conductor, the conductors connected to the central electrode of the piezoelectric element are guided to the outside through the interior of the tube, it being the case that they are surrounded in the interior of the tube by a jacket made from elastic material.

The transporting rake (32) bears a plurality of transporting lamellae (62-66) which can be pivoted perpendicular to the direction of displacement of the transporting rake and, during a displacement stroke, move shavings to a discharge conveyor (102) which runs transversely to the direction of displacement of the transporting rake, whereas it can move through the shavings situated in the hopper during the return stroke without appreciable transporting of material. <IMAGE>
Patent DE-3432145-A1 (DE)
Title: Method for correcting synchronism errors of at least two receiving channels with digital filters, in particular in multi-channel direction finders
Inventor: STAHL HORST DIPL PHYS
IPC: G01S3/04
Filed: 1984-08-31
Abstract: With the method, the disparities between the channels in multi-channel direction finders, for example, are equalised in terms of their transmission function by incorporating a correction value. The channels comprising analog and digital parts have digital filters into which filter coefficients selected by a computer are incorporated along with correction values. The correction values are obtained through calibration measurements with signals of different frequencies and amplitudes and are stored in a memory. System-specific noise quantities are thus advantageously eliminated from the received signals arriving from antennas. The method is fast due to the direct correction of the received signals. Furthermore, expensive analog circuits are not required to re-adjust or tune the channels.

IPC: E04C1/39
Filed: 1985-01-24
Abstract: A configuration, in particular of large building blocks, is to be provided which can be produced in the same way as conventional large building blocks but which permits on-site production of rounded corners of masonry structures, with low outlay. For this purpose, a corner region (7) of the block is separated from the main body (8) by a curved, convex predetermined breaking line (5) to which a curved outer web (11) is connected, at least on the side of the main body. The corner region (7) can thus be easily knocked off on site, with the result that a large building block having a rounded corner is provided. The knocked-off corner region (7) can be used to produce rounded portions on inner edges of the masonry structure. Combined production of a block with both a main body (8) and corner region (7) results in the conventional rectangular production shape. <IMAGE>

Title: Sprung suspension for a steered rigid axle on a vehicle
Inventor: HUNECKE JOSEF
IPC: B60G9/02
Filed: 1985-06-28
Abstract: A sprung suspension for the steered rigid axle on a vehicle is described, on the frame of which the rigid axle is suspended by means of a centrally arranged swivel bolt. At the same time the rigid axle interacts by way of a suspension with a self-aligning bearing capable of swivelling on the swivel bolt. In order to transmit forces acting on the rigid axle by way of the wheels in the vehicle's longitudinal direction into the vehicle frame without having to use components which, in the case of a driven rigid axle, restrict the freedom of movement of the driving propeller shaft, the self aligning bearing is designed as a transverse link, which is pivoted on the rigid axle outside the vertical longitudinal centre plane of the vehicle and a suspension is arranged between the transverse link and the rigid axle. <IMAGE>

Inventor: SCHMITT WALTER
IPC: G01B7/00
Filed: 1985-08-10
Abstract: In such a position-measuring device, a first binary signal (B1a) from a sensing unit (A) is fed via a first transmission line (L1) and a second binary signal (B2a) via a second transmission line (L2) of a transmission path (ST) to an evaluation unit (AW). For the purpose of detecting errors in the transmission of the two binary signals (B1a, B2a), a first redundant binary signal (RB1a) is generated upstream of the transmission path (ST) from the two binary signals (B1a, B2a) by means of a first exclusive OR gate (AG1) and a second redundant binary signal (RB2) is generated downstream of the transmission path (ST) from the two transmitted binary signals (B1b, B2b) by means of a second exclusive OR gate (AG2). The first redundant binary signal (RB1b) and the second redundant binary signal (RB2) transmitted on a redundant transmission line (LR) of the transmission path (ST) are fed to a comparator (V) in the evaluation unit (AW) to generate an error detection signal (FES) to characterise the equality or inequality between the two redundant binary signals (RB1b, RB2) (Fig. 1). <IMAGE>
