Patent DE-3637786-A1 (DE)
Title: Brake controller
Inventor: GLEIM GUENTER DIPL ING
IPC: H02P6/24
Filed: 1986-11-06
Abstract: The invention relates to a brake controller for an electronically commutated DC motor having sensors for detecting the rotor position and sensors for the rotation speed. Commutation signals for both the clockwise and anticlockwise directions are derived simultaneously in a converter (4), from the sensor for detecting the rotor position (2). When the rotor is rotating in a predetermined direction, commutation in the opposite direction is produced for a braking process. <IMAGE>

Title: Operating device for a vehicle roof
Inventor: FUERST ARPAD
IPC: B60J7/043
Filed: 1987-05-08
Abstract: Operating device for a vehicle roof with a cover (sun-roof) arrangement which in a closed position closes a roof opening, can be swivelled up into a deployed position and then can be slid back. Fixed on both sides of the roof opening are guide rails by means of which a respective first slider and a second slider, connected to a driving device, are slidably guided. The cover arrangement is supported pivotably on the first slider. The second slider is connected via a lifting device to a deploying lever which at its end which is remote from the first slider is connected pivotably to the cover arrangement. A locking device prevents the cover arrangement from sliding with relative to the guide rails as it pivots between the closed position and the deployed position. The other end of the deploying lever is connected pivotably to the first slider which is located on the relevant roof side. <IMAGE>

Title: Process for the preparation of propynol
Inventor: WESTERNACHER HELMUT DR
IPC: C07C29/60
Filed: 1987-05-23
Abstract: Hitherto, propynol has generally been prepared from acetylene and formaldehyde, with the acetylene pressures applied being high in some cases. However, this reaction also gives a considerable amount of butyne-1,4-diol. The backconversion of butyne-1,4-diol with the aid of a copper acetylide catalyst in the presence of a propellant gives propynol in high yields. Preparation of propynol.
Patent DE-3721381-A1 (DE)
Inventor: SAALMANN GUENTHER
IPC: D06F39/02
Filed: 1987-06-29
Abstract: The device has a receiving container and a rinsing-out space for the apportioned metering of, in particular, powdery cleaning material from the receiving container into the rinsing-out space for supplying industrial dishwashers or washing machines. A solution is to be provided which allows the metering both of satisfactorily pourable powder cleaners and of powder cleaners with lumps and the like, whilst always achieving essentially the same metering capacity even with different levels of the powder cleaner in the receiving container and additionally reducing the risk of moisture entering the receiving container from the rinsing-out space. This is achieved by metering holes (9) in the bottom (8) of the receiving container (2) and in each case a collection plate (10), arranged with spacing below the metering holes (9), and a scraping mechanism (11) which is movable in the space between the underside of the bottom (8) and the collection plates (10) and essentially wipes over the plate surfaces. <IMAGE>

Patent DE-3729210-A1 (DE)
Inventor: GRIGEL WOLFGANG DR
IPC: F23G5/32
Filed: 1987-09-02
Abstract: For the thermal elimination of waste materials, such as e.g. sewage sludge, special waste or the like, use has thus far been made of conventional waste burning techniques, in particular with grate firings. Such elimination methods are ultimately not environmentally tolerable and are also not economical. In order to be able to eliminate such waste materials environmentally tolerably and yet economically, it is proposed according to the invention to burn the waste materials, possibly after their comminution and possibly after their drying or preheating in a cyclone furnace (combustion cyclone or melting cyclone of high power density), at extremely high temperatures above 1500 DEG C, forming a molten slag (18) low in harmful substances and a hot waste gas (19), in which gas the useful substances and/or harmful substances contained in the waste materials evaporate, there being separated, separately from one another, from the waste gas, in each case by partial condensation, on the one hand dusts (25) enriched with useful materials and on the other hand dusts (29) enriched with harmful substances.
Patent DE-3730791-A1 (DE)
Title: Process for producing a rubber-covered cylinder
IPC: B41N7/06
Filed: 1987-09-14
Abstract: In the process for producing a rubber-covered cylinder for printing and coating machines, first of all a film is wound around a form for forming a sliding sleeve and then an elastomeric covering is applied and bonded to the sliding sleeve. In order for the production of such rubber-covered cylinders to be as inexpensive as possible, the covering is vulcanised after it has been applied and the film is applied only in such a thickness that the sliding sleeve bears against the form on account of a prestress brought about by the shrinking pressure of the vulcanised covering.

Title: Gate circuit
Inventor: SCHWEITZER WERNER DIPL ING
IPC: H03K17/51
Filed: 1988-04-23
Abstract: In a gate circuit for passing or inhibiting a clock signal as determined by a gate signal, four NAND gates are provided which are connected in such a manner that they logically combine the rising edge of the gate signal with a falling edge of the clock signal for switching-on and the falling edge of the gate signal with a falling edge of the clock signal for switching-off. The clock signal is thus switched without pulse shortening.

Inventor: RUDOLPH MARTIN
IPC: B29C48/00
Filed: 1988-08-09
Abstract: A tube of heated thermoplastic material which surrounds a woven reinforcing insert is stretched over a frame (2). The frame (2) is brought into a working position between a plunger (11) and a cavity (12) of a hydraulically operated compression mould (10). Upon actuation of the compression mould (10), the plunger (11) takes with it the tube stretched over the frame (2) and the woven reinforcing insert and brings them into the cavity (12). It is thereby achieved in one step and simultaneously that the heated thermoplastic material is bonded intimately with the woven reinforcing insert and the desired moulding is shaped. <IMAGE>

Title: Stereoscopic rail
Inventor: NEUSTADT ALF
IPC: G03B35/04
Filed: 1988-10-03
Abstract: A stereoscopic rail in which the carriage on which the camera is located is displaced by means of a motor. The motor is controlled by a microcomputer. The control permits the width of the basis and the centre of the basis to be preselected independently of each other. After the presetting, the two pictures of the stereoscopic pair are taken automatically and always in the correct sequence.

IPC: B60T8/48
Filed: 1988-10-11
Abstract: A method for the operation of a brake pressure control device for antilock control systems for hydraulic brake systems of motor vehicles is demonstrated. Between the master cylinder and the wheel cylinder circuit of the brake pressure control device an isolating valve (32) is arranged, which on conclusion of the control mode separates the master cylinder (3) on the one hand and the wheel cylinder circuit on the other until such time as a pressure level equal to the pressure level of the master cylinder has been achieved in the wheel cylinder circuit by means of a pressure medium pump (13). The invention ensures that, when control ends, the brake pedal remains stationary, that is it neither vibrates nor is returned. <IMAGE>
