Title: Valve for the control of fluid, in particular hydraulic, pressure medium especially for thrust-piston mechanisms of support elements in underground mine working
Inventor: NAUNDORF PETER ING GRAD
IPC: E21D23/16
Filed: 1983-06-18
Abstract: The valve has at least one piston displaceable in a bore of the valve housing, sealed off at its peripheral surface by a seal and forming the valve-closing body. So that a large cross-section of flow is available for the fluid flow and the valve seal is protected from wear, a tubular sleeve allocated to the piston is to be displaceably arranged in a valve-housing bore section of enlarged diameter. In the closed position of the valve, the valve piston is located with the seal in the narrow bore section, and the sleeve sits on a stop. In the passage position, the valve piston is located with the seal in the bore section of enlarged diameter, and the sleeve lifted from the stop covers the peripheral surface of the piston at least in the area of its seal. In many applications, the valve according to the invention enables the conventional seat valves subjected to high wear to be avoided and can be designed as a stop valve, as a multi-way valve or as a pressure-relief valve.

Title: Rear-viewing device for motor vehicles, in particular for road vehicles
Inventor: NIXDORF HANS WILLI
IPC: B60R1/10
Filed: 1983-08-09
Abstract: A rear-viewing device of this kind consists usually of rearview mirrors which are designed as centre-mounted mirrors or wing mirrors. Wing mirrors only ever show a portion of the traffic area behind the vehicle. Centre-mounted mirrors only permit the rear window of the vehicle to be seen through, this view depending considerably on the design of the vehicle body. If the rear window is obstructed, a centre-mounted mirror is of no use. Overall viewing of the area (10) behind the vehicle is however made possible in that a viewing device (2) is arranged on the vehicle roof (1a) and a receiving device (4) is arranged in the interior (3) of the vehicle and in that the image obtained of the area (10) behind the vehicle can be reproduced on a viewing screen (6) of the receiving device (4) by means of a transmission path (5) running through the vehicle roof (1a). The transmission path (5) is formed from electronic, optoelectronic or optical elements. <IMAGE>

Title: Adapter for a multichannel analyser
Inventor: STARK EBERHARD DIPL PHYS
IPC: G01N21/64
Filed: 1983-08-16
Abstract: With standard multichannel analysers, time resolutions, i.e. minimal channel indexing times, of 1  mu s can be achieved, e.g. in measuring fluorescence decay curves by the photon counting method. An adapter according to the invention reduces said time resolution to 50 ns by first transferring the photon pulses to an intermediate store (flipflop or counter) for the duration of the channel indexing time and then transferring them to a rapid RAM having, for example, 1024 memory cells (channels). When all the memory cells of the RAM are full, the multichannel analyser is started and the contents of the RAM are transferred to it at lower frequency. The circuitry of the adapter is of very simple construction because the entire time sequence control is undertaken by a single binary counter.

Title: Cart
Inventor: EBERLEIN HERBERT DIPL ING
IPC: B62B3/14
Filed: 1984-02-14
Abstract: Manually movable carts are known whose pushing device consists of two hoops provided at the rear end of the cart. Between the hoops, a basket for relatively small objects is arranged. This basket is an impedance if, for example, long flat objects are to be transported in an upended fashion. Therefore, the invention proposes a cart (1) in which the basket (9) is designed at least partially as a cantilever which extends transversely with respect to the direction of travel and is connected to the pushing device (6) in an articulated fashion in such a way that it can be moved out of a horizontal position of use into a downwardly directed position of rest. Thus, flat objects can be transported in an upended fashion regardless of the position of the basket (9). <IMAGE>

Title: Process for fabricating a semiconductor device
Inventor: SAWADA SHIZUO
IPC: H01L21/762
Filed: 1984-05-18
Abstract: A process for fabricating a semiconductor device comprises the steps of consecutive formation of a first oxide film, a first nitride film and a first film on a semiconductor substrate (101). In addition, parts of the first film, the first nitride film and the first oxide film are selectively etched so as to leave a first residual film (104'), a first residual nitride film (103') and a first residual oxide film (102'). In addition, part of the semiconductor substrate (101) is laid bare, thus providing a groove (107) having an inverted trapezoidal shape. A second nitride film and a second film are then successively applied, after the formation of a second oxide film (108), onto at least one inner surface of the groove (107) formed in the semiconductor substrate (101). Anisotropic etching of the second film is carried out to leave second residual films (110'), which film leaves at least part of the inclined surfaces (106a) of the groove (107) formed in the semiconductor substrate (101). Selective etching of a laid-bare part of the second nitride film is carried out by using the second residual films (110') as a mask. Etching of the second and first residual films (110', 104') and of the second laid-bare oxide film (108) is then carried out. A field-oxide film is then formed which, as an antioxidation mask, ... the first and second ... Original abstract incomplete. <IMAGE>

Title: Device for detecting the bending angle between the longitudinal axis of a tractor and the longitudinal axis of the towbar of a trailer
Inventor: LUSTFELD EIKE DIPL ING
IPC: B62D13/02
Filed: 1984-10-27
Abstract: The invention relates to a device for detecting the bending angle between the longitudinal axis of a tractor and the longitudinal axis of the towbar of a trailer. In accordance with Figure 1, the invention consists of a transmitter which has two parts (22, 23) which can be moved rectilinearly relative to one another, the two parts being a cylinder and a piston which is guided in the cylinder and provided with a piston rod. Provided in the cylinder (22) are a coil and a core which is connected to the piston and can be plunged into the coil. In the event of relative motion between the two parts, the inductivity of the coil changes, resulting in production of signals for controlling a valve device. Of the two parts (22, 23) which can be moved rectilinearly relative to one another, one can be connected to the tractor (1) and the other is or can be connected to the towbar (15, 5, 37, 4). A change in the distance between the two parts which can be moved relative to one another corresponds to a change in the bending angle between the longitudinal axis of the tractor (1) and the longitudinal axis of the towbar (15, 5, 37, 4). <IMAGE>

Title: Process and apparatus for separating out arsenic from hot exhaust gas produced in the metallurgical processing of arsenic-containing materials in melt processes
Inventor: BARIN IHSAN PROF DR
IPC: B01D53/46
Filed: 1985-04-22
Abstract: The invention relates to a process and an apparatus for carrying out the process for separating out arsenic from hot exhaust gas produced in the metallurgical processing of arsenic-containing materials in melt processes. Arsenic-containing impurities or condensates could not hitherto be prevented from being already separated out with the dust containing the valuable metal in a hot gas filter. By means of the invention, separation of arsenic-free dust, containing valuable metal, from the exhaust gas is achieved in that by addition of reducing agents, the oxygen partial pressure and sulphur partial pressure in the exhaust gas is controlled and adjusted in such a way that when exhaust gas temperatures are above 320 DEG C, arsenic-containing compounds are not stable in a condensed form.

Title: Installation for generating process steam by means of solar energy with direct evaporation and circulation of the heat transfer medium by natural convection
Inventor: HEINZEL VOLKER DR
IPC: F24S10/95
Filed: 1985-08-02
Abstract: An installation for generating process steam by means of solar energy with direct evaporation and circulation of the heat transfer medium by natural convection, with a solar collector which has a boiling pipe for generating and carrying off the steam to the consumer as well as, connected thereto, a supply pipe for the heat transfer medium, such as e.g. water, to be evaporated. The purpose of the invention is to design an installation of this type in such a manner that the air quantity contained in the circuit before starting can be stored in such a manner that the required operating pressure is kept in the installation at different capacity. To this end, the creation of an underpressure on cooling of the installation is to be prevented, that is to say it is to be possible for the stored air quantity to flow back to the collector or boiling pipe again. This is achieved by a collecting container 111 for the heat transfer medium, the liquid level 113 of which communicates with that 118 in the collector 101, the upper inlet pipe 114 being connected to the steam outlet of the collector 101 and the lower outlet 115 to the inlet 116 of the return run pipe 106. The collecting container can be connected both in series with the consumer and parallel to it. <IMAGE>
