Title: Circuit arrangement for checking the functions of telecommunications switching systems, in particular telephone switching systems
Inventor: GIEBLER HANS-JUERGEN DIPL ING
IPC: H04M3/32
Filed: 1984-06-30
Abstract: A circuit arrangement is provided to check the functions of telecommunications switching systems, in particular telephone switching systems, a peripheral adapter simulator being connected to local group control devices instead of a group of peripheral control devices via the existing assigned adapter interface. Either stimulus commands or command sequences generated manually via a test operating device are fed to this peripheral adapter simulator, or a simulation computer is used for this purpose. Furthermore, a group adapter simulator is provided which is connected like a centralised control device to a central data channel which connects the group control devices to one another and to the central control device. The commands to be transmitted on the central as well as on the peripheral data channel on the basis of stimulus commands from the centralised control device and from the local control devices are compared with the desired values provided in or fed to the adapter simulators and error protocols are generated if there is no correspondence.
Patent DE-3426575-A1 (DE)
IPC: F16L27/08
Filed: 1984-07-19
Abstract: A joint for a water-carrying pipe system, e.g. for a garden spray, has a joint shoulder with a disk-like part for each pipe end to be connected. The two disk parts are arranged on either side of the hose passed centrally through the joint. On either side of the joint, the hose is connected to the pipe ends in that it is passed through an opening, whose internal diameter is somewhat smaller than the external diameter of the hose. Thus, the hose engages flat on the openings of the pipe ends, so that this in itself leads to a liquid-tight seal.

Title: Method for winding closely wound winding layers, preferably without a gap, of layer windings, and a device for this purpose
Inventor: GRAUL OTTO
IPC: H01F41/06
Filed: 1984-09-14
Abstract: In the case of the method according to the invention for winding closely wound winding layers, preferably without a gap, of layer windings, especially for measurement transducers, test transformers or the like, the winding conductor is drawn off a winding conductor supply store, via a wire-guidance roller, from the winding layer which is to be wound, and is wound onto a coil former or onto the previously wound winding layer. The wire-guidance roller is displaced by a feed device, in each case in the direction of the just-wound winding layer, in such a manner that the wire-guidance roller of the turn of a winding layer which is to be wound lags by a predetermined lag angle. The lag angle ( alpha ;  alpha ') is monitored or measured by a sensor (17) and at least one actuating signal (S) or an actuating signal sequence is emitted by the sensor (17) if the lag angle ( alpha <+>,  alpha <+'>;  alpha <->,  alpha <-'>) is too large or too small, which signal or signal sequence accelerates the feed positively or negatively, in such a manner that the correct lag angle ( alpha ;  alpha ') is achieved. <IMAGE>

Title: Pneumatic control device for an exhaust gas throttle
Inventor: MEIER-GROTRIAN JOACHIM DR ING
IPC: B60H1/02
Filed: 1985-10-23
Abstract: In order to control the back-pressure of the exhaust gas which is produced by means of an additional exhaust-gas throttle (3) in the exhaust pipe (1) of the internal combustion engine (2) of a vehicle, the pneumatic control valve (6) for the exhaust-gas throttle (3) is connected via a control unit (8) to a vacuum source (12) or to the atmosphere, which control device (8) contains two flexible walls which are formed for example by in each case one diaphragm (21, 22) and one rigid plate (23, 24), the latter being rigidly connected. The said walls define a plurality of chambers (25, 26, 27) in a common housing (20) and are equipped with valves (34, 35) which are arranged in such a way that below predetermined values of the back-pressure of the exhaust gas a control pressure chamber (27) which is connected to the control valve (6) is connected to the vacuum source (12) and, on the other hand, at higher values of the back-pressure of the exhaust gas, it is connected to the atmosphere. <IMAGE>

Title: Gas-blast circuit breaker
Inventor: GRANDKE THOMAS DR RER NAT
IPC: H01H33/915
Filed: 1985-10-24
Abstract: In the case of an electrical gas-blast circuit breaker having two switching elements (1, 2) which, in the switched-on position, are bridged by a bridging switching element (3), the arc which is drawn is blasted with extinguishing gas over its entire length in the interruption path (T) during the switching-off process. For this purpose, the extinguishing gas is passed from an extinguishing-gas reservoir (10) exclusively via the channels (9) to the plate intermediate spaces (7) which are bounded in the insulating-material body (5) by radial plates (6). In the event of the interruption path being enlarged in order to cope with relatively large rated voltages, a simultaneous increase in the quantity of extinguishing gas required during the switching-off process is avoided by designing the gas-inlet cross-section in such a manner that its dimensions are smaller than the gas outlet cross-section. Arc blasting only via the plate intermediate spaces (7) leads to an improved radial flow, which is favourable for arc stabilization and cooling as well for deionizing the extinguishing-gas area surrounding the arc. <IMAGE>

Title: Device for producing flat sandwich elements
Inventor: TAUBENMANN PETER
IPC: B29B7/76
Filed: 1985-11-06
Abstract: The device for producing flat sandwich elements with a thickness of 60 mm and less (down to 40 mm) has a mixing head 1 having a cleaning plunger 3 which is movable back and forth in the mixing chamber 2. In order on the one hand to provide the high forces necessary for moving the cleaning plunger and on the other hand to keep the overall height of the device small enough for the device to fit between the individual cover layers of the sandwich elements, a plurality of plunger and cylinder units 12, 13, 14 are connected in series, preferably on a common plunger rod, so that the effective surfaces and thus the diameters of the individual hydraulic plungers 15, 16, 17 are correspondingly small. If these diameters are small, the overall height of the device is also correspondingly small, so that the device can be moved back and forth between the cover layers. The number of plunger and cylinder units connected in series is, at the predetermined hydraulic working pressure, dependent on the force required for moving the cleaning plunger 3. <IMAGE>

Title: Thermally conductive and electrically insulating interlayer for the build-up and fixing of semiconductor elements, and arrangement using such interlayers
Inventor: MANCHEN JOACHIM DIPL ING
IPC: H01L25/11
Filed: 1986-05-24
Abstract: The invention relates to a thermally conductive and electrically insulating interlayer for the build-up and fixing of semiconductor elements, in particular on cooling bodies. It is characterised in that, as the interlayer, an insulating cell (1) is used which externally resembles a wafer cell semiconductor but consists of a beryllium oxide wafer (2) with sandwich-constructed metal plates (3, 4) of a material of high thermal conductivity on both outer sides for contacting and of a peripheral synthetic resin compression-moulding (5) surrounding the whole. It is an advantage that the interlayer also has the same dimensions as the wafer semiconductors with which it is to be used. The possible uses are in this way improved. In addition to easier manufacture, the interlayer also has improved thermal conductivity due to the beryllium oxide material used. <IMAGE>

Title: Controller for operating fluorescent lamps
Inventor: CLASS EBERHARD DIPL ING
IPC: H05B41/295
Filed: 1986-07-17
Abstract: A controller for operating fluorescent lamps is provided with a voltage converter which produces AC voltages for operation of the fluorescent lamps. The voltage converter consists essentially of an oscillator having a fixed pulse duration, two pulse-duration modulators, a plurality of drivers and transformers. One of the pulse-duration modulators is used for producing a heating voltage for the fluorescent lamps. The starting/burning voltage for the fluorescent lamps is produced by means of the other pulse-duration modulator, whose pulse duration can be adjusted in order to vary the brightness of the fluorescent lamps. With the aid of a switched-mode regulator or the like it is possible to connect the voltage converter to any desired DC or AC voltages. A regulating device, which is coupled to the fluorescent lamps, can be used to ensure that fluorescent lamps having different operating characteristics can be operated without changing over the voltage converter. A switching-on delay device is provided in order to switch the fluorescent lamps on reliably and gently and with whose aid the starting/burning voltage is not switched on until a predetermined time interval has elapsed after switching on the heating voltage.

Abstract: A vehicle has an engine and a driven differential. The three-part drive shaft arrangement comprises a first, second and third drive shaft part. A first joint, which is a cardan (universal) joint, connects the output side of the engine to the one end of the first drive shaft part at the rotation end. A second joint makes a torsional connection between the other end of the first drive shaft part and a first end of the second drive shaft part. A third joint, with regard to a rotational movement, couples the other end of the second drive shaft part to the first end of the third drive shaft part. A fourth joint, which is a cardan universal joint, makes the torsional connection between the other end of the third drive shaft part and the driven differential. Two hanging bearings, which are respectively arranged close to each end of the second drive shaft part, rotatably support this drive shaft part on the vehicle body. Of the second and the third joint, one is a cardan joint, the other is a constant velocity joint. The phase position of the two cardan joints, which flank the constant velocity joint on both sides, is the same, whilst the phase position of the other cardan joint is offset by 90 DEG  in relation to the common phase position.

Title: Device for controlling points in gravity-shunting systems
Inventor: LEBEK HANSJOERG
IPC: B61L7/08
Filed: 1986-11-13
Abstract: Points to which it is intended to provide access both from an automatic gravity-shunting system (SEWA) and from the interlocking cabin, have a switch which can be adjusted when the automatic gravity-shunting system is switched on and by means of which the point unit (RWG) of the interlocking cabin is separated from the drive (A) and the drive is connected to the automatic system (SEWA). This takes place by means of exclusion contacts (WAU/1 to WAU/4, WAU/5 to WAU/8) of the switch. The presence of a drive which is located in its limit position is simulated for the point unit (RWG) by means of further contacts (WAU/9, WAU/10) of the switch for the duration of the automatic operation. Connection and disconnection routines ensure that the actual position of the drive coincides, when the control is assumed by the interlocking cabin or the automatic system, with the set position stored in the interlocking cabin or the set position which is taken into account by the automatic system. <IMAGE>
