Patent DE-3729911-A1 (DE)
Title: Synchronism control of processing stations
Inventor: BRAUN ALBRECHT
IPC: H02P5/56
Filed: 1987-09-07
Abstract: In processing machines with several stations, between which synchronous operation is required, digitally controlled individual drives are provided in place of toothed-wheel gears. The control signal is formed by evaluating series of pulses which, on the one hand, come from incremental transmitters on the individual processing stations and, on the other hand, from a central control clock pulse and/or the transport device which connects the processing stations. By this means, advantages arise in the freedom with which equipment changes can be made and, when setting-up, furthermore the possibility of introducing register controls. The adaptation parameters which take into account the dimensions can, inter alia, be taken into account by a method in which the desired position of the drives as a function of the control movement is programmed into a memory and then recalled at the frequency of the control movement.
Patent DE-3730560-A1 (DE)
Title: Method and device for transmitting pulse signals
Inventor: HAASE JOST-MICHAEL
IPC: H03M5/08
Filed: 1987-09-11
Abstract: In order to transmit pulse signals having binary values "0" and "1", it is proposed that the binary values "0" and "1" of the pulse train are converted on the transmitting side into pulses of different length, and that a pulse train having binary values "0" and "1" is derived anew on the receiving side with the aid of the pulses of different length. As a result, a serial high-speed data transmission at baud rates of several megabytes/sec can be performed without simultaneous transmission of a synchronising clock pulse (signed), i.e. via a single-channel conductor.

Patent DE-3742326-A1 (DE)
Title: Gritting unit
Inventor: HUBER IGNAZ
IPC: B60B39/08
Filed: 1987-12-14
Abstract: Poor carriageway contact when the carriageway surface is icy or slippery with snow leads to increased risk of skidding when braking, accelerating and cornering both with summer and winter tyres. Speedy starting at junctions is also not possible under such conditions. In the preconditions described in point 1, with the aid of a compressor - which is switched on by an additional switch on the dashboard - the gritting unit can be used to blow quartz sand from a supply container via a hose system onto the carriageway in front of the wheels. Contact with the carriageway is substantially improved. The unit can also be used as a traction aid. As has been demonstrated in testing, some of the dry quartz sand remains stuck to the moist tyres and as a result increases its frictional effect. All motor vehicles. In the case of front-wheel drive for the two front wheels, in the case of rear-wheel drive on all four wheels.

Title: Method for producing a superstructure for railways
Inventor: HERTLE EDMUND
IPC: E01B1/00
Filed: 1988-06-15
Abstract: To produce a superstructure for railways which forms a solid travelway, a bitumenously bonded supporting layer, as used in road construction, is prepared or slabs are laid on the formation. A top levelling layer of asphalt concrete can be applied to the slabs. With the travelway prepared in this manner, the track grid consisting of tracks screwed to concrete sleepers is then adhesively bonded by a bitumen- and/or plastic-based casting compound. To avoid having to fill the gaps formed between the sleepers with suitable materials, concrete sleepers lying close to one another or separated from one another by only narrow gaps are adhesively bonded to the travelway, the widths of which sleepers correspond in each case approximately to the widths of the conventional sleeper and a conventional adjoining space between sleepers.

Patent DE-3823833-A1 (DE)
Title: Automatic safety door locking bar which takes effect due to gravity and is intended for the doors of houses, cellars and flats
Inventor: FINDEISEN FELIX DR
IPC: E05C21/02
Filed: 1988-07-14
Abstract: The conventional safety door locking bars require, for operation from the outside, a special deadlock and, in addition to mounting of the locking-bar enclosures in the wall, also the mounting of the locking bar on the door itself. In the case of the novel safety door locking bar, the intention is, despite the fact that operation can likewise be carried out from the outside, that a special deadlock with key be dispensable. Mounting of the locking bar on the door itself is intended to be dispensed with. Production and mounting are intended to be simplified. After the door has been closed, the safety door locking bar (1) according to the invention falls, by virtue of its own weight, into the locking-bar enclosures (2 and 5) fitted on the wall, on either side of the door. When the door is opened, by virtue of actuating the normal door lock (8), a latch (6) of the locking-bar closure (5) on the door-closure side is disengaged and the locking bar, by virtue of its own weight, drops out of this locking-bar closure. The device is suited as a simple, but stable break-in safeguarding means for exterior doors in houses and flats. <IMAGE>

Inventor: KOPLIN KARL-HEINZ
IPC: H01R39/14
Filed: 1988-11-12
Abstract: In a slip ring arrangement for the rotor of an electrical three-phase current generator for motor vehicles or the like, it is proposed to link the end of the slip ring holder to the rotor or armature spindle by pushing it over a smaller-diameter journal of the rotor spindle and securing it axially by making it a force fit or, for example, by means of splines, where plastic-coated busbars run from the slip rings in grooves in the armature spindle beneath the ball-bearing and their broadened ends are soldered to the excitation winding connecting wires. Alternatively, the slip ring holder may be secured to the journal or a bearing neck pressed into the end of the rotor spindle by a clip, while prestressed leaf springs ensure axial clearance. In both cases, the flange of the slip ring holder pushed over the armature spindle and the fan fitted at the same place may be in one piece, whereby the metal parts of the fan are laid in the extrusion or compression mould for making the plastic bearing housing together with slip rings and busbars, and the housing is formed around them.

Title: Valve for the metered addition of evaporated fuel to the fuel/air mixture of an internal combustion engine
Inventor: BALLHAUSE LUTZ DIPL ING
IPC: F02M25/08
Filed: 1989-03-08
Abstract: A tank-venting valve for the metered addition of evaporated fuel to an internal combustion engine has a valve housing (10) with inlet and outlet branches (11, 12), between which is arranged an electromagnetically operated seat valve (30). The inlet branch (11) is connected to the vent branch of a fuel tank and the outlet branch (12) is connected to the intake pipe of the internal combustion engine. To prevent the internal combustion engine from running on when the ignition is switched off, the seat valve (30) is designed in such a way that it is closed when de-energised. To allow adaptation of the cross-section exposed when the seat valve is opened to the vacuum at the outlet branch (12), the valve opening (16) with the valve seat (17) is supported by a diaphragm (13) which divides the valve housing (10) into an inlet chamber (14) and an outlet chamber (15). Depending on the magnitude of the vacuum prevailing in the outlet chamber (15), the diaphragm (13) bends out and pushes the valve seat (17) to a greater or lesser extent towards the spatially fixed travel stop (231). This reduces the opening stroke of the valve member (19) and hence also the exposed aperture cross-section of the seat valve (Fig. 1). <IMAGE>
