Title: Pneumatic-stowing wall
Inventor: NOECKER GUENTER
IPC: E21F15/04
Filed: 1986-09-13
Abstract: In pneumatic stowing in underground coal mining, a pneumatic- stowing wall is used together with a special face support with back-cantilevered bar. The pneumatic-stowing wall runs over the entire length of the face but in each case consists of individual pneumatic-stowing walls of 7500 to 9000 mm in length. Each of these individual pneumatic-stowing walls is in turn composed of sections in a modular manner, which are present at least in pairs and can be exchanged for one another. These sections have shielding consisting of two plates displaceable in the perpendicular relative to one another, the displacing plate being guided via rods which have a push-in device and thus permit fixing at the respective height. The chocks carrying the shielding have pivotable skids which always ensure that the pneumatic-stowing wall is in a perpendicular position. The anchor rope required for stabilising is firmly clamped via clamping cylinder to the pneumatic-stowing wall in such a way as to additionally fix the latter. <IMAGE>

Title: Device for interference-free determination of the adjustment or setting of an angle or path of a carrier exhibiting coded information
Inventor: HEINEMANN GERHARD DIPL ING
IPC: H03M1/24
Filed: 1986-11-11
Abstract: In one device, a rotatable coding disk is provided as carrier on which angle and/or distance information is digitally coded in the form of annularly arranged openings passing through the coding disk. To ensure interference-free angle measurement and transmission, one pair of optical fibres is allocated to each annular digital information track formed by the openings. In each case, one optical fibre of a pair of optical fibres scans either the top or the bottom of the coding disk with one end whilst the other ends of these optical fibres are in each case connected to an optical fibre branch. The optical fibre branches connect the optical fibres to in each case one optical feeder fibre which is connected either to a transmitter sending out short-time light pulses or to a receiver receiving the light pulses. In each case, one optical fibre pair delays the light pulses compared with an adjacent preceding pair of optical fibres in such a manner that when a light pulse is sent out by the transmitter, the receiver receives a serial message of pulses which contains the distance or the angle of the coding disk as digital information coded compared with the reference quantity. The coding disk of the device can be preferably coupled to a flap, which can be adjusted on the basis of a steering command, a rudder or the like on vehicles. <IMAGE>

Title: Shutter for rolling shutter doors
Inventor: BAUER SIEGFRIED
IPC: E06B9/15
Filed: 1986-11-14
Abstract: The arresting parts fitted on side borders of the shutters of rolling shutter doors require window-free profile-bar ends, this rendering difficult or impossible the production of the shutters from profile bars prefabricated with their window openings. The novel shutter for rolling shutter doors is intended also to be able to exhibit profile-bar ends provided with window openings. In the case of the shutter for rolling shutter doors, the arresting parts (20, 20') are configured such that, even in the case of ends of the profile bars (10, 10') being located in window openings (11'), they form, by means of relatively wide wall webs (22), stable profile-bar termination bridges. The arresting parts (20, 20') are anchored in grooves (13, 14) formed on the profile bars (10, 10'), and they are fixedly clamped in said grooves by caulking the groove borders. The shutter for rolling shutter doors can be made up of profile bars (10, 10') which can be formed by cutting lengths off extruded sections, which are prefabricated with their window openings (11, 11'), without taking into account whether the ends of the profile bars (10, 10') run through prefabricated window openings (11'), since, owing to the configuration and fastening of the arresting parts (20, 20'), stable profile terminations can be provided even in the case of profile bars terminating with window openings (11'). <IMAGE>

Patent DE-3727331-A1 (DE)
Title: Brake pressure control device
Inventor: GRAEBER JOHANNES
IPC: B60T8/40
Filed: 1987-08-17
Abstract: The invention relates to a brake pressure control device, especially an antilock device for hydraulic brake systems for motor vehicles, comprising a master cylinder 4, a hydraulic brake booster 3, a pressure medium source 5 and a pressure modulator 2 for varying the hydraulic pressure during the control mode. The modulator essentially comprises a modulator piston 32 and a modulator chamber 15 to which pressure can be admitted, and a pressureless chamber 34. The controllable pressure level in the pressure modulator chamber governs the brake pressure control during the control mode. The pressure in the modulator chamber is controlled by a solenoid-operated modulator opening valve 37 and a solenoid-operated modulator check valve 38. For more rapid discharge, that is for a more rapid pressure reduction in the modulator chamber, a modulator check valve 40 is provided, which is hydraulically operated and has a large flow cross-section. By means of the said hydraulically operated modulator check valve a rapid reduction of the back pressure in the modulator chamber is achieved with the said valve in the open position, when the brake pressure control device is operated in normal braking mode. Due to the rapid reduction of the pressure in the modulator chamber, a harmful back pressure is prevented, which in normal braking mode would counteract the force of the brake pedal and the booster. <IMAGE>

Patent DE-3801886-A1 (DE)
Title: Combined gas and steam turbine power station with charged fluidised-bed furnace
Inventor: BEULE ERHARD
IPC: F02C3/36
Filed: 1988-01-22
Abstract: In a combined gas and steam turbine power station with charged fluidised-bed furnace, a highly effective de-dusting of the flue gas is necessary for safe operation of the gas turbine. Further problems in known designs arise in the area of the immersion heating surfaces of the stationary, charged fluidised-bed furnaces and during part-load operation. The new method is structured in such a manner that an effective de-dusting can be carried out at a temperature around 250 to 450@C, the turbine inlet temperature of the flue gas lies at over 700@C to achieve good efficiency, and the furnace can also be controlled well during part-load operation. The method works with a circulating pressure-charged fluidised-bed furnace (11) as furnace system, some of the heat exchangers (15, 16, 17) being arranged directly above a fluidised-bed chamber (14). The flue gas is, after an effective de-dusting (23), mixed with by-pass air (5), heated to approximately 750@C in a heat exchanger (15), and then expanded in a gas turbine (2). In heat exchangers (16, 17, 20) of the steam generator system, high-pressure steam is generated, with which a steam turbine (39) is driven. The method serves for generating electrical energy from solid fuel. <IMAGE>

Title: Detent mechanism for an actuating linkage of a motor vehicle parking brake
Inventor: MAYER JAKOB
IPC: B60T7/08
Filed: 1988-07-01
Abstract: Releasable parking brakes on motor vehicles are not safeguarded against accidental release due to rotation of a rod of their actuating linkage and disengagement of a detent element. A new detent mechanism for such an actuating linkage is therefore intended to reliably preclude accidental rotation of the rod. This is achieved by locking of the detent element, occurring automatically when the rod (1) is fixed, which locking prevents rotation of the rod (1) and can be disabled by displacement of the rod (1) in order to apply the parking brake. <IMAGE>
