Title: Process for preparing copper/copper oxide catalysts, the catalysts obtained in the process, and their use
Inventor: LAGALY GERHARD PROF DR
IPC: C07C15/00
Filed: 1981-06-10
Abstract: The invention relates to a process for preparing copper/copper oxide catalysts on the basis of silicate supports. According to the invention, an alkali metal sheet silicate (phyllosilicate) or alkaline earth metal silicate or silicic acid is reacted with a copper salt solution and aqueous ammonia solution, ammonia optionally being removed, at a temperature of at least 80 DEG C. The product obtained is then isolated and dried in a conventional manner or, after isolating and drying, converted into the supported copper catalyst by reduction with hydrogen. The invention further relates to the use of the catalysts obtained in the process for hydrogenation, dehydrogenation, oxidation and chlorination reactions.

Title: Electrohydraulic actuator for turbine valves
Inventor: TRASSL WERNER DIPL ING DR
IPC: F16K31/363
Filed: 1981-07-23
Abstract: Electrohydraulic actuator for turbine valves (5), especially for control, quick-closing and by-pass valves of steam turbines, the said actuator comprising an electrohydraulic convertor, a hydraulic actuating cylinder (7) supported on the valve housing by at least two supports, an energy accumulator spring (13) acting in the closing direction of the turbine valve (4), and an electric motor (16) for driving a hydraulic pump which is connected, on the delivery side, to at least one hydraulic accumulator (17) and which pumps hydraulic fluid out of a reservoir (2) into the actuating circuit, all the components being integrated to give a compact driving block arranged on the valve housing. The shell (15) of the reservoir (2) surrounds the actuating rod (9), passing through the reservoir (2), of the hydraulic actuating cylinder (7), the energy accumulator spring (13) and the supports, the space between these components thus being used to accommodate the hydraulic fluid. In this arrangement, the base plate (1) and cover plate (8) of the reservoir (2) are rigidly connected to the supports, allowing the non-load-bearing shell (51) to be designed as a removable cylinder and allowing easy access from outside to the components arranged inside the reservoir (2). In addition, the hydraulic pump can also be arranged completely and the hydraulic accumulator (17) at least partially inside the reservoir (2). <IMAGE>
Patent DE-3136751-A1 (DE)
Inventor: SONTHEIMER KARL
IPC: F02M55/00
Filed: 1981-09-16
Abstract: In order to prevent erosion of the pump housing caused by the fuel stream exiting from the return flow openings at the end of injection, it is proposed that the fuel injection pump be provided with an impact protection ring pushed over the cylinder bushing. Adjacent to a cylindrical wall portion, the impact protection ring carries a radially outwardly bent, circular-annular collar. The collar rests on an abutment shoulder disposed above the return flow openings and has an end face whose area is a multiple of the cross sectional area of the cylindrical wall portion. The impact protection ring encloses an annular chamber, provided with a narrow radial gap (s), in the vicinity of the return flow opening and is pressed by a snap ring against the abutment shoulder. As a result of the pressure build-up in the annular chamber and as a result of a slide bearing effect between the collar and the abutment shoulder, a rotational movement of the impact protection ring triggered by the obliquely exiting fuel stream is assured, for the purpose of attaining long service life of the fuel injection pump.
Patent DE-3140783-A1 (DE)
Title: Elastic mount with hydraulic damping
Inventor: EBERHARD GUENTER DR
IPC: F16F13/10
Filed: 1981-10-14
Abstract: A hydraulically damped engine mount with a controlled throttling device, the free cross-section of flow of which is closed off statically, avoiding a change, due to the vibrations, in the position of contact of a diaphragm held with free travel between supporting plates. As a result, the throttling device only comes into action in the event of relatively large vibration amplitudes whereas, at higher frequencies and hence smaller amplitudes, the cross-section of flow remains open. Both the damping and acoustic performance of the mount are thereby considerably improved.

Title: Process for producing silicon which can be used for semiconductor components, in particular for solar cells
Inventor: GRABMAIER JOSEF DR RER NAT
IPC: C30B15/00
Filed: 1981-12-21
Abstract: In this method, the starting point is SiO2 and carbon having a boron and phosphorus content of < 1 ppm. The molten silicon produced after reduction in an arc is caused to solidify in an inert-gas atmosphere in a preheated trough (1) by uniform and controlled removal of heat from the melt surface, the crystallisation process being accelerated, for example, by introducing a thin silicon rod (2). The solidified ingot (5) is then separated from the residual melt (6) containing the impurities. The novel method is capable of removing, in particular, impurities, such as titanium, vanadium, iron, molybdenum, zirconium, which reduce the efficiency of the solar cells. <IMAGE>

Title: Rail-bound gallery vehicle for underground working
Inventor: MEISSEL KLAUS PETER DR ING
IPC: B61D11/00
Filed: 1982-04-03
Abstract: Rail-bound gallery vehicle for underground mining working with supporting structure, chassis and bodies, the supporting structure having a longitudinally running central member and the chassis consisting of two twin-axle bogies with bogie cross-member, at least one of which bogies being connected by its bogie cross-member to the central member via a spherical joint. The bogie cross-members have on the two sides axle rocker arms which are supported counter to a restoring spring so as to be swivellable about a horizontal axis. The axles of the wheel are mounted in their axle rocker arms with an axle spherical joint. The axle rocker levers are positioned on their axles, designed as bearing bolts, with bearing play in the direction of the wheel axles. In this way, even in the case of considerable buckling, constraints on the axle rocker arms during their adjustment are avoided. In this way, it is ensured that when travelling over disturbed sections of rail in underground mining works all the running wheels of the chassis remain on the rails and, as it were, stick to the rails, specifically even at a high speed. <IMAGE>

Title: Method and circuit arrangement for determining the value of the ohmic resistance of an object being measured
Inventor: SCHWARZ CHRISTIAN
IPC: G01R27/02
Filed: 1982-04-15
Abstract: In a method for determining the value of the ohmic resistance of an object being measured, on which noise voltages are present, a measuring direct voltage (Uo1) having a low voltage value and a measuring direct voltage (Uo2) having a higher voltage value are successively connected to the object being measured. The influences of the noise voltages are eliminated by measuring and evaluating the measured voltages (Um1, Um3) by means of a voltmeter (UM) and an evaluating circuit (AW), at the same time ensuring high measurement accuracy.
