Title: Error-protected light-signal control device with fewer wires
Inventor: BRAUER HARRI DIPL ING
IPC: G08G1/097
Filed: 1982-06-23
Abstract: The invention relates to an error-protected light-signal control device with fewer wires, for several light signals, with primary and secondary filaments, of an at least 2<v>2 microprocessor system. The invention consists in that one frequency is allocated to each signal term and one frequency generator each is provided for each signal term in each of the processor channels. The light signals are activated over a single channel via the frequency generators and via output amplifiers allocated to each of the processor channels and protected comparators for the primary and secondary filaments. The result of the comparison is signalled back to the microprocessor system via distributors. The outputs of the processor channels are connected to a decentralised signalling bus via a protected comparator. The outputs of the processor channels are connected to a disconnecting or change-over device which triggers a blocking signal in the case of an error. <IMAGE>

Title: Cable with laminated cable covering and process and device for the continuous manufacture thereof
Inventor: RABENECKER KLAUS ING GRAD
IPC: H01B13/26
Filed: 1982-07-02
Abstract: Cables that are to be laid underground or the like have a cable covering (11) surrounding the cable core assembly (10), which functions as conductor. Since this also has to absorb mechanical loading, it comprises an outer cable jacket (12) and an inner cable jacket (13), the latter being manufactured of a metal or aluminium tape (14), which must be completely insulated. For this purpose, the invention provides for the coating of the metal or aluminium tape (14) on both sides with a film (15), the films (15) projecting over both lateral longitudinal edges (16, 17) of the metal or aluminium tape (14). The lateral projections (18) thus formed of the films (15) are joined during injection covering of the inner cable jacket (13) moulded around the cable core assembly (10) with the outer cable jacket (12) to form homogeneous fused edges (20), a coating of the longitudinal edges (17, 18) of the metal or aluminium tape (14) also being carried out. <IMAGE>

Title: Drive assembly for motor vehicles, especially buses, with a hydrodynamic unit and a continuously variable transmission
Inventor: PICKARD JUERGEN
IPC: B60K6/10
Filed: 1982-07-03
Abstract: A drive assembly for motor vehicles, especially buses, operates with a hydrodynamic unit driveable via its input shaft by an engine and with a continuously variable transmission for transmitting a rotary motion by endless flexible traction means, in particular chains. The output shaft of the hydrodynamic unit can be brought into drive connection with the input shaft of the continuously variable transmission via a three-axle stationary transmission. The output shaft of the continuously variable transmission is coupled to vehicle wheels in a customary manner. The input gear of the stationary transmission, which gear is driveable by the output shaft of the hydrodynamic unit, and the output shafts of the hydrodynamic unit and the continuously variable transmission are arranged in alignment with a main axis. For the use, known per se, of a ring gear meshing with a driving pinion as the drive connection for a flywheel acting as an energy accumulator, a short overall length in the directions of the main axis is achieved in the drive assembly by virtue of the fact that the ring gear is arranged both centrically relative to the main axis and also in a manner fixed in terms of rotation relative to the input gear, and the teeth of the ring gear and the input gear face one another, and a coupling hub, on the one hand, which is fixed in terms of rotation relative to the input gear, and an output flange, on the other hand, which is fixed in terms of rotation relative to the output shaft of the hydrodynamic unit, are connected to one another by a one-way clutch, and the one-way clutch and that cross-section of the ring gear which has the teeth are each arranged approximately centrally relative to a reference plane perpendicular to the main axis.

Title: Method for stepping the stator rotating field of a synchronous machine onwards
Inventor: SEELIG ANTON ING GRAD
IPC: H02P25/03
Filed: 1983-02-25
Abstract: The invention relates to a method and an arrangement for stepping the stator rotating field of a synchronous machine onwards as a function of the rotation angle, without having to use an angle detecting device which is installed in or on the machine. A converter which is equipped with semiconductor switches which can be disconnected allows the operation of the synchronous machine in a condition in which there is no significant phase shift between the block-shaped, intermittent current of each winding phase and the e.m.f. induced therein by the rotating rotor. An electronic angle detecting device detects the e.m.f. induced by the rotating rotor, in the current gaps, by means of its zero crossovers and from this, determines the angular position of the rotor, according to an integration method, and the signal (FS) for onward stepping of the stator rotating field. <IMAGE>

Title: Method for determining the distribution of the contact pressure of a specimen inside a contact zone by means of a mating body, and device for carrying out the method
Inventor: HERMANN WALDEMAR
IPC: G01L1/06
Filed: 1983-03-03
Abstract: The method determines the distribution of the contact force of a deformable specimen. For this purpose, a locally limited deformation is produced in the region of the contact zone of the specimen by means of a mating body. Measurement is made, over the width of the contact zone, of the respective distance between a line of action of the force producing the deformation and a point at which the region deformed by this force merges into the region that is not affected by the locally limited deformation. This transition point is formed by a line which specifies the distribution of the contact pressure in the contact region. The device for carrying out the method has a mating body which is provided in the region of the contact zone with at least one point of distortion.

IPC: H04N5/217
Filed: 1983-03-19
Abstract: According to a method for correcting faulty pixel signals of transducer elements of an optoelectronic transducer stage of an electronic image processing device, constant light is applied to the optoelectronic transducer stage (1). The pixel signals are compared with the signals of a tolerance circuit at the rate of the pixel frequency. For the pixel signals which are outside the tolerance range, correction value signals are generated and stored in the correct relationship with the pixels in a read-only memory. With respect to the coding, a distinction is made between a first group for correctable transducer elements and a second group for non-correctable transducer elements. <IMAGE>

Title: Pressure control valve
Inventor: SCHELHAS PETER ING GRAD
IPC: G05D16/20
Filed: 1983-04-29
Abstract: A pressure control valve having a baffle plate is proposed, which is used for controlling a specific pressure drop. The pressure control valve comprises a first control valve (76, 80) and an armature (85) which is located in an electromagnetic field produced by an electromagnetic coil (99) and in a permanent-magnet field and is supported such that it can pivot between in each case two pole shoes (90, 91, 94, 95) which are provided on both sides of the armature (85). The pole shoes (90, 91) on one side of the armature (85) have a magnetic polarity, caused by the permanent magnet (101), which is opposite to that of the pole shoes (94, 95) on the other side of the armature (85). When the electromagnetic coil (99) is energised, which moves the moving valve part (80) of the first control valve away from the control valve seat (76), the valve part (80) opens the moving valve part (104) of a second control valve (105), via which a high-pressure line (42) can be connected to an operating space (77). <IMAGE>

Title: Apparatus and method for comminuting wood
Inventor: GUTMANN ADOLF
IPC: B27L7/00
Filed: 1983-07-19
Abstract: An apparatus (1) (Fig. 1) serves for comminuting wood, in particular old wood and the like, interspersed with metal parts. It essentially comprises a cutting tool (2) having a cutting edge oriented approximately transversely to the grain of the wood to be cut up. The cutting tool essentially comprises, on the delivery side, a rear side (13) which is approximately straight in the cutting-edge direction, and, on the front side, a wedge slope (15). As a result, the wood is cut up transversely to the grain and at the same time the severed wood layers are successively displaced along the grain and dissected into logs. Consequently, the wood is simultaneously cut up, in one operation, with respect to the length, into predeterminable pieces which are simultaneously split in the longitudinal direction. A conveyor belt (24), arranged on the feed side and intended for feeding the wood to be comminuted, can be pressed down, at least in the region of its delivery end in the cutting tool (2), against a restoring force, so that during the separating process the wood can rest on a corresponding abutment (21) and does not load the belt. <IMAGE>

Patent DE-3416864-A1 (DE)
Inventor: MICHEL DIETER ING GRAD
IPC: G01D5/38
Filed: 1984-05-08
Abstract: A photoelectric measuring system includes a graduation field in the form of a phase grid. An outer field is provided for the graduation field, and this outer field is likewise formed as a phase grid. The phase grids of the graduation field and the outer field have different grid constants, so that the diffraction images generated by them impinge in different places on an array of photodetectors which are circuited together antiparallel to one another. In this way a push-pull signal is generated which can be reliably evaluated and is well suited for use as a reference signal.
Patent DE-3417984-A1 (DE)
Title: Mobile plant for granulating liquid manure
Inventor: RIECHELMANN HARRY
IPC: C05F3/06
Filed: 1984-05-15
Abstract: Agriculture is faced with new problems, on the one hand caused by concentrated intensive livestock keeping, whereby excessive amounts of liquid manure are produced, of which, at the best, only half can be utilised on the farm's own fields. This causes problems mainly because of the new "Liquid Manure Acts", which state that in some countries, under certain circumstances, unprocessed and undeactivated liquid manure can no longer be applied to the fields, because of the excessively high nitrate content of the ground water. On the other hand, there are many, in particular large, arable farms where no animals are kept, hence no natural fertilizer is produced. In order to transfer the natural fertilizer over substantial distances from one farm to another, the liquid state of the manure is the most uneconomical version possible once transport goes beyond a certain distance. This is why the fresh liquid manure is processed in biogas plants and biologically and bacterially deactivated. The bulk of the resulting product will have remained the same, despite the energy obtained in the form of gas. This liquid bulk is now separated in the granulating plant and the solids are dried and granulated. These granules, which are a dry natural fertilizer, can be stored more easily and their transport is more economical. Investment in a granulation plant, which only takes up a small amount of space, is much more favourable than large plants involving several tanks of a diameter of 15-20 m and a height of 6-10 m ...

Title: Printing device for typewriters or similar office machines for optionally printing on a recording medium in vertical and/or landscape format
Inventor: RITTBERG EILT-HEYO DIPL ING
IPC: B41J1/30
Filed: 1984-09-06
Abstract: To fill in forms or even to label diagrams, writing is required both in the line direction and in the column direction. Printing devices should therefore be suitable for optionally printing on a recording medium in portrait or landscape format. The object of the invention consists in providing a printing device, in which portrait and landscape recordings can be produced optionally by the simplest means. One of the features of the invention is that the type carrier has solid character printing types to produce portrait and/or landscape recordings and that a control device is provided, by means of which the writing step pulses in the case of portrait recordings can optionally be fed to the drive device for the type carrier and, in the case of landscape recordings, to the drive device for the recording medium and the line switch pulses in the case of portrait recordings can be fed to the drive device for the recording medium in the column direction and, in the case of landscape recordings, to the drive device for the type carrier. As a result, texts in vertical and/or landscape format can be produced without manual interventions both in the case of sheet-type and in the case of continuous recording media. <IMAGE>

Patent DE-3434744-A1 (DE)
Title: Process for producing hot-rolled bars
IPC: C21D8/06
Filed: 1984-09-21
Abstract: Processes are indicated for producing hot-rolled bars for the fabrication of machine components which can be highly stressed statically and/or dynamically. Precipitation-hardening and/or fine grain-forming microalloyed steels are used as a material. The bars are first rolled, in particular in such a way that the rolling is completed in a temperature range from 800 DEG C to 1150 DEG C. If this is not possible, the bars are subjected to a special heat treatment after rolling and, starting for this from a temperature at which the microstructure is ferritic-perlitic, heated to a temperature between 800 DEG C and 1000 DEG C. In both cases, the bars are then further treated purposefully in such a way that they are cooled under control from a temperature within said ranges. The cooling is here carried out by means of a suitable coolant at a cooling rate, which effects precipitation-hardening and/or fine grain formation and produces as complete as possible a ferritic-perlitic microstructure in the bar material, while avoiding a significant formation of bainite, to a temperature at least 50 DEG C below that at which the transformation into ferrite and perlite is complete.
