Title: Tank for a sewage pumping station
Inventor: CORDES WILLI
IPC: E03F5/22
Filed: 1983-09-30
Abstract: In a tank for a sewage pumping station for accommodating pumps (17), said tank being produced from a building material such as concrete or the like and being of a rotationally symmetrical shape, a central pump chamber (16) is formed by an inner casing (12) which extends cross-sectionally along a continuous line and which, together with the outer casing (11) of the tank, forms an annular collecting chamber (13) for the incoming sewage. This arrangement makes it possible to keep the sewage moving in a constantly circulating manner before pumping out into the collecting chamber (13), with the result that thorough mixing of the individual constituent parts of the sewage is obtained and long-term depositing of solid constituent parts is avoided. <IMAGE>

Title: Apparatus for the anaerobic treatment of effluents
Inventor: WEISSGAERBER HARTMUT DR ING
IPC: C02F3/28
Filed: 1983-10-03
Abstract: An apparatus is to be developed in which the reaction tank required for the digestion, the gas store and the heat transfer system are integrated in a vessel, this apparatus being completely gastight against its surroundings. This is achieved by arranging a heat-conducting cylindrical partition vertically in a digestion vessel which is furnished with a movable gas hood. This partition divides a reaction tank located in the interior from an outer tank filled with a barrier liquid which surrounds the reaction tank in an annular manner. The bottom end of the movable gas hood is constantly immersed in the barrier liquid and thus creates a gas-tight connection. Within and/or outside the outer tank, a heating device for heating the barrier liquid is provided. The invention is used in the treatment of municipal and agricultural effluents, in particular in the treatment of liquid manure from chicken, pig or cattle husbandry. <IMAGE>

Title: Process for separating solid portions in sludge-like masses and apparatus for carrying out the process
Inventor: KUPCZIK GUENTER DIPL ING
IPC: B01D21/00
Filed: 1985-05-29
Abstract: In a process for separating, in particular organic and mineral, solid portions in sludge-like masses, they are brought to a flowable state having a solid portion in the order of magnitude of 12 to 18 % by volume in a liquid and are forced by a pressure through a transport section which is restricted in cross-section. The conditions are chosen in such a way that an appropriate turbulent flow induces a separation of the solid portions from each other and this separation is maintained in the liquid. The apparatus for this purpose has a hollow pipe whose length and cross-section are dimensioned in such a way that the turbulent flow is generated between the start and the end, the same flow velocity being maintained at the end as at the start, which ensures an energy loss in the region of the reaction section, which energy loss ensures separation of the solid portions as a result of the turbulent flow. <IMAGE>

Title: Tilting mechanism for unlocking an electrical contactor
Inventor: BLANCHARD JEAN-YVES
IPC: H01H71/50
Filed: 1985-07-30
Abstract: The invention relates to a tilting mechanism for unlocking an electrical contactor, having a moving contact lever, a control device (10) for unlocking and a lever (1) which can pivot about a shaft (2) and has on the one hand a groove (4), into which one end (5) of the moving contact lever engages, and on the other hand a stud (6) on which a device rests which can rotate about a fixed shaft (13) and is supported by the control device (10) for unlocking. According to the invention, this device is a roller bearing (14, 15) which is coaxial with respect to the fixed shaft and is in rotating contact with a single roller (7). This roller is supported on the opposite side on the stud (6), which is a cylindrical surface whose radius of curvature is equal to the sum of the diameter of the roller (7) and the radius of the roller bearing (14, 15). In the locked switching state, the centre of this radius of curvature is located in the centre of the fixed shaft (13). Such a tilting mechanism requires very little control energy for unlocking the contactor. <IMAGE>

IPC: B62D7/22
Filed: 1985-08-22
Abstract: A locating bearing (1) for a shaft which bears an obliquely toothed pinion of a toothed rack steering system for motor vehicles and is constructed as a roller bearing with roller bodies (5) which roll between two raceways (3 and 4) and on which axial forces act when the shaft (2) rotates has, in the non-actuated state of the steering system, a higher rotational resistance than in the actuated state as a result of the fact that the locating bearing (1) is constructed as a four-point ball bearing, one of whose raceways (3) bears a race which is divided in the area of the raceway (3) into two parts (8 and 9) in a plane running at right angles to its longitudinal axis, which parts are axially displaceable with respect to the component (7) which bears them and rest, with prestressing, against the balls (5) under the effect of springs (10, 11) which are supported on the said component (7), the part (8 or 9), which is respectively acted on by the axial force, of the race being displaceable, under the effect of the said force, by a larger amount of displacement in the direction of action of the said force than the respectively relieved part (9 or 8) of the race under the effect of the spring (11 or 10) which is assigned to the said part (9 or 8). <IMAGE>

Title: Liquid-cooled nuclear reactor having a nuclear-element decay store cooled in the natural circulation
Inventor: DUEWEKE MICHAEL DIPL PHYS DR
IPC: G21C15/26
Filed: 1985-08-26
Abstract: For liquid-cooled nuclear reactors having a tank-internal decay store for spent core elements (46), especially for liquid-metal-cooled breeder reactors, it is proposed to cool the decay store not only during emergency operation but also in normal operation just by natural-convection flow. For this purpose, the spent fuel elements are accommodated such that they are screened from the reactor core so that no significant power is released into them exceeding the afterheat. In addition to the known separating wall (7) which splits the reactor tank (1) into a hot header (31) and a cold header (32), there is a further separating wall (8) so that an intermediate space (9) is formed. Temperature conditions occur in this intermediate space which promote the coolant circulation through the fuel elements (46). <IMAGE>

Title: SO2 production for the simultaneous scrubbing of SO2 and NOx in simultaneous scrubbing units downstream of flue gas desulphurization units
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/60
Filed: 1985-08-28
Abstract: A process for SO2 enrichment for the simultaneous scrubbing of SO2 and NOx from flue gases. It is known, that in particular in slag-tap-fired boilers, the ratio SO2 to NOx is sometimes unfavourable in such a way that a useful action for separating out NOx is not ensured. For this reason it is known to add pyrosulphite to the scrubbing liquid. In order to avoid this, according to the invention it is proposed that the gypsum obtained from the flue gas desulphurization process is admixed, thoroughly mixed and distributed, to the coal to be burnt and is added above the burner in the combustion process chamber for SO2 release.
