Patent DE-3133397-A1 (DE)
Title: Method for digital videotelephony
Inventor: DIRR JOSEF ING GRAD
IPC: H04N7/24
Filed: 1981-08-24
Abstract: An impediment to the introduction of videotelephony, whether analog or digital, is the great bandwidth required up to the video telephone subscriber. Although optical fibres are suitable for this purpose, they are very expensive. Building up the optical fibre video telephone networks would take decades. The connection of video telephone subscribers in remote areas is uneconomic. In the invention, the information, as the picture elements and possibly the voice and control signals, is coded on a digital binary basis. The transmission occurs preferably by radio. As a binary code, two amplitude values, a large one and a small one, of a halfwave or period of an alternating current which are transmitted in direct sequence are provided. In this arrangement, the small amplitude value is, at the most, half as large as the large amplitude value (Figure f1/f2). The connection to a videotelephony network can be effected in frequency- (Figure f1/f6) and/or time-division multiplex (Figure fz) with direct modulation of the transmitted alternating current, and/or by carrier frequency. The invention can be used both in subscriber-dialling (Figure K1...K4) and conference videonetworks, in point-to-point connections, that is to say particularly in face-to-face communication. <IMAGE>

Patent DE-3150381-A1 (DE)
Title: Method and installation for avoiding ovality in the bending of tubes
Inventor: BASTEN HELMUT DIPL ING
IPC: B21D7/025
Filed: 1981-12-16
Abstract: The invention relates to a method for avoiding ovality in the bending of tubes, in particular in bending with partial heating. In order to counteract the ovality of the bend which generally arises in the bending of large tubes during the bending process itselt, it is proposed that a pressure acting on both sides of the tube and reversed, if required, at the end of the bend, is exerted immediately in front of or behind or in front of and behind the heating zone in at least two mutally perpendicular planes during the bending operation, the said pressure bringing about a preovalisation both in the horizontal bending plane and perpendicularly thereto in the elastoplastic region of the material, and this preovalisation allows for a reversed springback. To achieve this, an installation is used as characterised in Claims 5 to 7. <IMAGE>
Patent DE-3150571-A1 (DE)
Title: Guard rail for guiding wheeled vehicles having flangeless lateral guidance
IPC: E01B25/28
Filed: 1981-12-21
Abstract: The invention relates to a guard rail for wheeled vehicles having flangeless lateral guidance, which comprises a guiding surface disposed approximately perpendicularly to the trackway and serving to bear the steering rollers of the wheeled vehicle. For the purpose of moving the wheeled vehicle into and out of the trackway, and when cross-traffic traverses the trackway, it is necessary for the guard rails to be removable for a short time. For this purpose, the invention proposes that the guard rail section with the guiding surface which projects perpendicularly over the trackway edge be capable of being sunk into a housing whose upper edge lies approximately at the level of the upper side of the trackway, the guard-rail section in the sunken position lying approximately at the same level as the upper side of the trackway and thus being capable of being driven over. The sinking mechanism required for this purpose is advantageously arranged in the housing which receives the guard-rail section. It is thus possible for the guard-rail sections to be sunk or moved back into position as required.

Title: Driving head for pneumatic driving equipment
Inventor: JENNE GUSTAV DR ING
IPC: E02D13/10
Filed: 1982-02-02
Abstract: The invention relates to a driving head for pneumatic driving equipment, in particular for pile hammers and self-propelled percussion drilling rigs, with a percussion piston which is axially movable in a reciprocating manner in a housing and whose percussion energy can be transmitted to the driving head arranged at the front side of the housing. In order to provide a light and handy driving head which is inexpensive to produce, covers larger diameter ranges for the material to be driven in and is secured against release from its connection with the material to be driven even under vibratory stresses, there are formed in the end face of the driving head a conical annular surface and a thread into which a displacement head piece or a pin-like attachment driving piece with in each case a cone piece corresponding to the conical annular surface and a mating thread corresponding to the thread can alternatively be inserted in a positive-locking but releasable manner in the axial and radial direction.
Patent DE-3205625-A1 (DE)
Title: Sensor
Inventor: WOLF KONRAD DIPL ING
IPC: G01D5/20
Filed: 1982-02-17
Abstract: A sensor serves to detect rotation speed and/or reference marks, in particular of toothed discs (10) in motor vehicles. In this arrangement, a thin ferromagnetic plate (13) onto which two coils (L1, L2) are wound is arranged opposite the teeth of the toothed disc (10). The plate (13) is exposed to the magnetic field of a permanent magnetic plate (14), the magnetic field penetrating the plate (13) being modulated by the teeth of the toothed disc. The coils (L1, L2) form a differential arrangement in this case, so that the measurement signal is independent of the air gap between the plate (13) and toothed disc (10). <IMAGE>
Patent DE-3205908-A1 (DE)
Title: Single-phase rapid-action coupler with sideways displacement
Inventor: KRAUTLOHER FRANZ
IPC: B60D1/46
Filed: 1982-02-19
Abstract: It is known to equip motor vehicles with 3-point working hydraulics and single-phase rapid-action couplers. These single-phase rapid-action couplers, usually triangles with locking elements, have however the disadvantage that they are not laterally movable. In practical use, the processing of edges and a working width compensation of the motor vehicle with respect to the working machine, particularly when going round a bend and working on a slope, is not possible (when travelling over harvested material with the tractor rear wheels). The invention is based on the object of constructing a rapid-action coupler in such a way that it is laterally displaceable. The problem has been solved in that the coupling triangle is movably mounted on a transverse carrier. Between the coupling triangle and transverse carrier a drive is attached. A special upper link, provided with an additional rotary joint and a running roller, which on the tractor side is mounted on a running rail ensures favourable matching to the floor and a constantly identical upper link length. The main areas of application are the tractor industry and agricultural machinery industry.

Title: Installation for generating electrical energy which is to be supplied into a network
Inventor: FABER EGON DR DIPL ING
IPC: H02K7/18
Filed: 1982-03-11
Abstract: A slow-running diesel engine (1), an electrical synchronous generator (4) with a network (R, Y, B) and a diesel engine flywheel form a system which is capable of rotational oscillation. An additional mass (7), which rotates at a greater speed than the synchronous generator, is coupled to the synchronous generator (4) via at least two identical pairs of gear wheels (5, 6), the pairs of gear wheels (5, 6) being braced against one another in such a manner that the kinematic effect of the tooth-edge play is cancelled out. In consequence, the additional mass can follow all the changes of the rotational movement of the system in the time domain kinematically, without play. <IMAGE>

Patent DE-3230747-A1 (DE)
Title: Vibratory plate
IPC: E02D3/074
Filed: 1982-08-18
Abstract: A vibratory plate is proposed which, in the way of this generic type, consists of a top mass (1) carrying the drive motor (3) and of a bottom mass on which the vibration exciter (5) is mounted. The motor (3) drives the vibration exciter (5) via a mechanical drive connection (6). The invention solves the problem of keeping dirt and dust away from the mechanical drive connection (6) by virtue of the fact that at least the drive connection (6) is surrounded by a two-piece hood, the parts (8a, 8b) of which vibrate relative to one another with the top mass (1) and the bottom mass (2) respectively, and that a positive pressure relative to the atmosphere is produced inside the hood (8) by means of a blower (14). <IMAGE>

Title: Input and output processor for a telecommunication system
Inventor: LIEBSCHER ROLAND DIPL PHYS
IPC: G06F15/167
Filed: 1982-10-15
Abstract: To relieve the main processor of a processing unit, the data transfers between it and its environment (peripherals, communication network) are exclusively carried out via input and output processors. The CPU used for this is a commercially available I/O processor 5 which, although it is designed for fast data transfer, must, as coprocessor ("slave"), be usually controlled by a higher-level "master" processor. This large hardware expenditure is avoided by a starting circuit 7 which supplies the hardware signals SEL, CA required for initialisation. During the initialisation, the coprocessor reads the required program blocks out of a nonaddressable memory (ROM) and the system then switches to a RAM memory for normal operation. Application for controlling telecommunication systems, for example videotex computer centres, teleaction and office communication systems. <IMAGE>

Title: Gate-array semiconductor integrated circuit
Inventor: MUELLER JAKOB ING GRAD
IPC: H01L27/118
Filed: 1982-10-15
Abstract: The object of the invention is an advantageous design of such a basic cell in relation to the layout. Each basic cell has two parallel supply lines provided by a conductor track in each case and an equal number of p-channel and n-channel transistors which are each situated in a rectangular region. In each of these two regions, all the transistors are situated between the two supply lines and are oriented, on the one hand, parallel to the supply lines in relation to their source-drain sections. On the other hand, both the p-channel transistors and the n-channel transistors are arranged inside the two regions accommodating them in each case along one or along a plurality of lines which extend parallel to the two supply lines. Furthermore, each n-channel transistor or each p-channel transistor is associated with at least one complementary transistor of the other region, their gates being interconnected by a common line which extends directly across the gates, in a straight line and perpendicular to the two supply lines. The terminals of these gate connection lines, which serve for connection to other basic cells or to peripheral switching circuits, are arranged on the other side of the one or the other supply line. Between the two regions, each of the gate connection lines mentioned has a connecting point in each case (see Figure 2). <IMAGE>

Title: Method for radar signal processing
Inventor: TOEDTER HANS-HERMANN DIPL ING
IPC: G01S13/536
Filed: 1982-11-26
Abstract: The transmission signal of an FM-CW radar is periodically modulated with a sawtooth waveform. The phase of the transmission signal at the beginning of each sawtooth wave is used as a control by forming a coherent reference signal. After the received signal has been mixed with the reference signal coherent with the transmission signal, the filtered-out intermediate-frequency signal thus obtained is sampled, digitised and subjected to fast Fourier transformation. The results are separated according to frequencies (filters) and subjected to a second transformation, which differs from Fourier transformation in terms of phase angles only. The filter outputs of the first transformation are thus separated according to Doppler speeds. For echoes of moving targets with a specific radial velocity, the roughly estimated distance value obtained from the first Fourier transformation can be corrected.

Title: Loader having a mounted side-mowing/clearing unit or clearing unit
Inventor: MAUL FRANZ
IPC: A01D90/12
Filed: 1983-02-17
Abstract: For daily green-fodder collection or the like with normal tractors and loaders, it is advantageous if the material is loaded simultaneously with the mowing by means of laterally arranged mowers, the aim being to achieve this at low power and to ensure that as few fractions of dirt, foreign bodies or the like as possible infiltrate into the loaded fodder. It is advantageous, at the same time, if the loader remains in the same track of the tractor during the mowing and loading. For this, a side-mowing unit, combined with a clearing unit (14, 24), can be connected to the drawbar (2) of a normal loader (3) or to the front side of this, the clearing unit throwing the mown material laterally in front of the pick-ups (28) of the loader (3). At the same time, the impurities are to a large extent filtered off, and if a cutting unit with knives moving to and fro is used the necessary drive power is relatively low. If, for example, a mid-mounted side-mowing unit (14) is already present in accordance with the operating conditions, only one corresponding clearing unit (24) need also be connected to the loader. <IMAGE>
