Patent DE-3029250-A1 (DE)
Title: Correcting short wave bearing faults - using fast computer for comparison of known with quickly-taken reference bearings
Inventor: DAMBOLDT THOMAS DR RER NAT
IPC: G01S3/10
Filed: 1980-08-01
Abstract: The fault correction method uses a remote controlled short wave carrier of a modern bearing station-controlled by a microprocessor or larger computer - to tune in to a large number of transmitters with a known location, and take bearings automatically. These bearings are then compared in the computer with the known base lines and the discrepancy determined. With the correction so evaluated, (for which information about transmitter frequency, distance to known transmitters, approximate distance of unknown transmitter etc. must also be processed), the bearing of the unknown transmitter can be correctly determined. In this way, the unpredicatable, random fluctuations in the ionosphere which cause the faulty readings, can be taken into consideration. With the use of fast-frequency changing receivers and sufficiently fast computers, the bearing calculation can be processed before the propagation conditions change.

Title: Machine tool overload protection system - comprises plate lifted off seat by spindle against hydraulic pressure
Inventor: SCHROEDER KLAUS JOCHEN ING GRA
IPC: B21D22/14
Filed: 1980-10-01
Abstract: The machine tool overload protection system is for use where the spindles moving the work and/or the tool are at right angles to each other. One at least of the spindles works with a valve plate between a high- and a low-pressure chamber in a valve housing and the plate is held by oil pressure in the high-pressure chamber against a valve seat (17) as long as the maximum permissible pressure on the spindle (3) is not exceeded. When the pressure is exceeded, the plate lifts off the seat, allowing the oil to flow from the high-pressure chamber (4) to the low-pressure one(5).
Patent DE-3038931-A1 (DE)
Title: DC power supply voltage stabiliser for motor vehicles - uses astable multivibrator controlled by feedback amplifier
Inventor: SCHLINKERT HERBERT DIPL ING
IPC: H02M3/156
Filed: 1980-10-15
Abstract: A solid state switch is the main control element between the supply voltage and the stabilised output. The regulator comprises a feedback amplifier, constant voltage source, level detector and astable multivibrator with inverting and non-inverting outputs. A capacitor forms an oscillating circuit with the amplifier output resistors. If the output voltage is low the feedback is insufficient to break over the Zener reference diode, and the amplifier is off. The oscillating circuit drives the multivibrator at h.f. causing the control switch to operate at the same rate and the output voltage rises. When the Zener diode breaks over the amplifier gives an output which reduces the oscillation frequency and hence the rate of the multivibrator thus causing the output voltage to drop. The output voltage thus tends to take the value of the reference element.
Patent DE-3043371-A1 (DE)
Title: Stereo disc master production - involves cutter control to minimise distance between adjacent recording grooves
Inventor: STRUCK GUENTHER
IPC: G11B3/70
Filed: 1980-11-17
Abstract: A cutting process for the production of a stereo disc master is designed to enable the distance between adjacent grooves to be minimised. The process has a turntable (ST) on which the master disc (IT) is located. The cutter (5K) is moved by a motor (M) under the control of signals generated by a groove feed logic unit (RVL). Signals are obtained from magnetic tape using two pick-ups (HK1,HK2) that deliver stereo signals to a groove control stage (RAL). Here a built in computer unit (MR) generates a value that is subtracted from the horizontal feed signal to provide adjustment of the feed.
Patent DE-3048745-A1 (DE)
Title: Solid fuel boiler firing control thermostat - has safety device to prevent overheating by overriding action if thermostat fails
Inventor: LEESE WERNER ING GRAD
IPC: F23N5/24
Filed: 1980-12-23
Abstract: The boiler is fitted with a thermostat to control the water temperature. A capsule (2) inside the housing (1) contains a liquid which expands when heated to the control temperature so that the capsule and its attached bracket (13) are forced downwards against the force of a spring (6). The boiler air inlet flap is normally held open by a chain (9) attached to a lever (8'). The downward movement of the capsule and bracket removes the support from this lever so that the air flap is no longer supported and swings to the closed position. The spring abuts against a ring (15) of a material which softens at a temperature higher than the maximum permissible water temperature. In the event of a thermostat failure this ring collapses and allows the air control flap to close.

Patent DE-3104064-A1 (DE)
Title: Chain connector for a hauling chain of an underground chain conveyor, an underground winning machine or the like
IPC: F16G15/04
Filed: 1981-02-06
Abstract: Belonging to the chain connector are two identical, essentially U-shaped chain-connector halves, which form a connecting eye for a chain link to be put in, a closing piece and a clamping pin. The chain-connector halves interlock with complementary positive-locking shapes. The clamping pin can be inserted into a bore passing through the chain-connector halves and the closing piece. The chain-connector halves have a long and a short U-leg. The U-legs reach over one another in the assembled state. One of the U-legs has a positive-locking peg and the other U-leg has a corresponding, closed receptacle for the positive-locking peg. The clamping pin can be inserted into a bore which runs through both U-legs of each chain-connector half orthogonally to the direction of the acting tensile force in the assembled state. In this way, the closing piece does not have to absorb any tensile forces and consequently can be held merely by the clamping pin, and in addition the bending moments in the chain-connector halves and the production costs are reduced. <IMAGE>
Patent DE-3105797-A1 (DE)
Title: Turbulent burner
Inventor: BATES WILLIAM GRISCOM
IPC: F23D14/70
Filed: 1981-02-17
Abstract: Turbulent burner having a burner block and an opening which extends, in general, in the longitudinal direction and is intended for the passage of fuel and air maintaining the combustion. The burner block exhibits a shell which is formed in it at the outer end of the opening, a sleeve in the opening which, for its part, has a passage for the air, a fuel line which extends along the opening and is intended for channelling fuel to a location in the sleeve, and a restricting device which is borne by the sleeve and is intended for restricting the fuel flow essentially to a turbulent movement within the sleeve and also for mixing with the air for the formation of a turbulent air/fuel mixture, the sleeve being outwardly open for the passage of the air/fuel mixture from the sleeve into the depression. The burner is characterised in that the depression (105) has an outwardly convex curvature which forms an outwardly arched surface, along which the products of combustion flow, in that the outer dimensions of the sleeve (107) are smaller than the inner dimensions of the opening (106) and form a channel (109') therebetween which is shorter than the opening (106). <IMAGE>
Patent DE-3106418-A1 (DE)
Title: Method and arrangement for storing spent fuel elements
Inventor: BAATZ HENNING DR
IPC: G21F9/36
Filed: 1981-02-20
Abstract: The invention proceeds from a method for storing spent fuel elements, the spent fuel elements being inserted into a shielding container arrangement, and fed in the shielding container arrangement to an interim decay store. In the interim decay store, the initial activity of the gamma rays decays to a residual activity of gamma rays which depends on the interim storage time. The decayed fuel elements are put into an ultimate storage site. In this case, the spent fuel elements are inserted into a shielding container arrangement which consists of a metallic inner container and a metallic outer container. The inner container is set up as a shielding container for the residual activity of the gamma rays, whereas the shielding container arrangement as a whole is set up to shield the initial activity of the gamma rays. Consequently, the spent fuel elements can be fed with the inner container to ultimate storage. There is therefore no longer a need for expensive reloading of the decayed fuel elements from a container personally dimensioned only for interim storage into a container intended for ultimate storage. The subject matter of the invention is also a corresponding container arrangement, the inner container being designed as a shielding container for only the residual activity of the gamma rays, while the container arrangement as a whole also shields the initial activity of the gamma rays when the containers are placed one inside another. The interspace between inner container and outer container can be encapsulated with the aid of a fusible metal alloy.

Filed: 1981-02-26
Abstract: In the case of this door, adaptation of the base height, which is determined by the lower edge of the door, to the kitchen furniture base is possible, without an additional adjustable screening base, which is separated by means of a joint, being necessary below the door. To this end, the door is divided up into a door upper part (1) and a door lower part (5), the continuous extension and sliding together of the two door parts being respectively possible to permit adjustment to the base height. The door supports a joint-free continuous decoration plate (4). <IMAGE>
Patent DE-3108095-A1 (DE)
Title: Fixing device in a photocopier
Inventor: KNECHTEL WILHELM
IPC: G03G15/20
Filed: 1981-03-04
Abstract: For the purpose of fixing a powder image, a toner can be fused by heating or by pressure, depending on its property. For purely pressure-fixing, use is made of cold rollers between which the copying paper sprayed with powder passes. A force which is large enough to fix the toner is exerted on the ends of the rollers. In this design, however, the pressure distribution is distributed irregularly over the length of the rollers, with the result that uneven fixing is obtained or, if the press rollers are of convex shape, a fold is rolled into the paper. In accordance with the invention, at least one of the rollers is constructed as a tube with a concave lateral surface. In the interior and in the centre of such a roller a support bearing is provided which loads the roller with the aid of a spindle or shaft, so that it bears against the mating roller along a line. The result of this is that the pressure distribution over the entire length of the roller is constant, and the roller can have a relatively small roller diameter, resulting in a saving in overall height, and in that, furthermore, the outlay on materials remains small, resulting in the achievement of a reduction in cost for the fixing device. <IMAGE>

Title: Common-wave radio network
Inventor: BUERK HANS ING GRAD
IPC: H04H20/67
Filed: 1981-07-03
Abstract: In a known common-wave radio network with a master station, secondary stations and a plurality of relay stations, the transmission from the relay stations to the master station is also carried out in common-wave mode. The receiver is selected in the master station using the RF suppression effect. For this purpose, the transmission power is adjusted in the relay stations from the secondary stations according to the receive level. To enable the master station to identify which station is receiving it, the relay stations transmit audio signals for signalling purposes using the timing pattern method. Due to the RF suppression effect, the master station normally receives one relay station only which it can identify by the position of the audio signals in the timing pattern.
