Patent DE-2923288-A1 (DE)
Inventor: YOKOTA MITSUHISA
IPC: F01K13/02
Filed: 1979-06-08
Abstract: The control device for the low-pressure bypass duct is equipped with a pressure adjusting mechanism (30) which comprises a first transducer element (41), generating an output signal j1 proportional to the input signal h1 originating from the pressure detector (32), and a second transducer element (42) whose output signal j2 is inversely proportional to the input signal h2 originating from the pressure detector (32). A delay circuit (43) and a pressure regulator (37) allow a pressure adjusting signal to be generated for the low-pressure bypass duct. A high-values priority circuit (36) compares the output signal j1, the output signal j2 and an output signal j3 sent out by the pressure regulator (37). In a comparator (38), the signal k, originating from the pressure detector (31), is compared with a signal  l , sent by the high-values priority circuit (36), so as to produce a signal making it possible to control a control circuit (39) for proportional adjustment and adjustment by integration (PI circuit) and a pressure reducing control circuit (40). This device constitutes a combination between an adjusting mechanism of the usual type and a turbine bypass adjusting mechanism, for controlling the main steam stop valve and the superheated steam stop valve and thus makes it possible to carry out general control for a steam turbine installation. <IMAGE>

Title: Nuclear reactor accident protection - disposing molten core in deep shaft under the core pressure vessel
Inventor: SCHWANTES ECKART DR ING
IPC: G21C9/016
Filed: 1979-08-04
Abstract: A liquid-cooled nuclear reactor is protected against breakdowns leading to melting of the complete core by arranging below the cavern, containing the reactor core, a deep shaft (1000 m deep) into the strata below the ground water bearing formations. The concrete shell of the cavern has an intentionally weak area above the shaft, to ensure that this area melts first before the molten mass can break out sideways. This requires no costly cooling system nor does it causes any excessive pressure rise inside the steel safety sphere. The solidified melt needs no costly disposal measures.

Patent DE-2941664-A1 (DE)
Inventor: LIEBERT HORST
IPC: C03B37/10
Filed: 1979-10-15
Abstract: In the manufacture of mineral-wool mats or slabs, the raw materials are melted in a melting furnace and are spun to fibers in a spinner. The fibers, after admixture of a resin binder, are deposited so as to be formed to wool mats in a collecting chamber, then cured, trimmed at the sides and cut up into lengths. Both during spinning and during trimming, cutting up into lengths and a subsequent final inspection and check for defects, waste products arise. In order not to have to deliver these waste products, as hitherto, to a proper dump but, instead, to be able to recycle them direct to the production process, the waste products are broken up into smaller pieces and/or unravelled, heated and then briquetted while hot, whereupon the briquettes, possibly after cooling down and interim storage, are combined with the raw materials which are to be melted and thus returned via the melting furnace into the production process.

Title: Prepn. of apovincaminic acid ester(s) - by azeotropic dehydration of vincamic or epi-vincaminic acid ester(s); useful at hypotensives and vasodilators
Inventor: SZANTAY CSABA DIPL ING CHEM DR
IPC: C07D461/00
Filed: 1979-10-31
Abstract: Prepn. of (+)- or (2)-apovincamic acid esters of formula (I) is carried out by dehydrating a (+)- or (-)-vincamic acid ester of formula (II) or a (+)- or (-)-epivincamic acid ester of formula (III); (where R is 2-6C alkyl). Dehydration is effected in a water-immiscible solvent which forms an azeotropic mixt. with H2O, in the presence of a strong organic acid which as a dissociation constant of >=10-2, does not conform an azeotropic mixt. with H2O and has a low vapour pressure at the reaction temp. The H2O formed in the reaction is continuously removed by azeotropic distn. Cpds. (I) are useful as hypotensives and vasodilators. The process gives practically quantitative yields of high-purity (I) free of (II) or (III).
Patent DE-3002972-A1 (DE)
Title: Feeding powdered coal to high pressure reactor - by extruding moist coal into high pressure gas stream, drying and sepg. dry extrudate
Inventor: KESSLER RICHARD VERNON
IPC: C10J3/50
Filed: 1980-01-29
Abstract: Drycoal is fed to a high pressure gasifier vessel by feeding powdered coal having a predetermined percentage of water to an extruder. The mixt. is continuously extruded into a high pressure stream of gas so that it is dispersed into powdered coal mixed with the gas stream. The stream is then dried and the dry dispersed extrudate separated from the gas and fed into the gasifier vessel. Pref. the drying is by upward flow in a high pressure fluidised dryer using superheated steam as the heat source sepn. occurs in a high pressure cyclone separator. The sepd. gas is cooled, has water in it removed and is recirculated after being compressed. The feed arrangement enables the feeding of a high concn. of coal/water mixt. into the high pressure system so that in many cases the natural coal and water content is close to the concn, required for extrusion. Thus, little if any, additional water is necessary. The energy required to dry the coal under pressure is about the same as that required if the coal were dried and then injected.

Patent DE-3026592-A1 (DE)
Inventor: THRANDORF HANS-PETER
IPC: B65H3/12
Filed: 1980-07-14
Abstract: The aim of the invention is, independent of the condition of the sheets as regards pre-curvature and stiffness, to achieve unhindered passage of the separated lowermost sheet of a stack below a stop to the further-conveying device. This requires the sheets to be drawn by suction air to a conveyor element into a position in which pre-curvature is compensated and no new curvatures are produced by the effect of the suction elements and jamming of a plurality of sheets below the stop is prevented. A stacking table (1) and a circulating suction belt (7) are arranged at an angle and pivotably with respect to one another in the conveying plane. The region, lying foremost in the separation direction, of the stack projecting above the stacking table bears against an adjustable stop (4). <IMAGE>

IPC: B23Q1/54
Filed: 1981-03-06
Abstract: An assembly table (36) is connected to a supporting frame (31) located below it via two double levers (40, 41). The double levers have pivots (46 to 51) which are arranged at an angle to one another so that the assembly table is lifted absolutely parallel to the supporting frame (31) when a lifting unit (65) is actuated. In addition, with regard to the optimum accessibility of the assembly point, the assembly table (36) is of pivotable design. For this purpose, the top arm (42) of one double arm (40) is divided into a lower section (52) and an upper section (54) which are mutually rotatable about a journal (53) integrally formed on the lower section. The assembly table (36) can thus be pivoted via a drive acting on the upper section (54). Since the upper arm section (54) rotates in the process about an axis (A) inclined obliquely to the main plane of the assembly table, a compensating device (55) is provided. A further drive means consists in mounting the lower part of the bottom arm (43) in a lever (67). The lever, pivotable about a pivot (70), is connected to a hydraulic unit (73), upon actuation of which the lever (67) is pivoted in the direction of the arrow (P1). The device can be used as a lifting and tilting device for assembly lines in automobile construction, as an assembly table for the universal machining of machine parts, etc. If necessary, the second double arm (41) can also be provided with a rotary mechanism of corresponding design, including a drive, so that the assembly table (36) can be inclined in any direction. <IMAGE>

Title: Detachable and replaceable heat and splash protection for oxygen lances for steel production
Inventor: MENGELKOCH OTTMAR
IPC: C21C5/46
Filed: 1981-06-04
Abstract: Oxygen lances are water-cooled steel pipe constructions by means of which oxygen for decarburisation is blown through one or more blow nozzles into the liquid melt during steel production in a converter. The tip of the lance is generally made of copper and wears rapidly owing to considerable heat, splashing melt and slag. Sprayed-on, welded-on and sintered-on protective layers and the failure thereof in the case of large temperature fluctuations and mechanical stresses (cracking, peeling, impossible or difficult to repair) are known. According to the invention, this is prevented by a protective cap of heat-resistant materials (ceramic, glass ceramic, metal oxides, etc.) which has the same shape as the lance tip and is placed over the latter before the blowing process and fixed by detachable connections. The protective cap can be replaced after one or more blowing processes.
