Title: Simultaneous separation-off of SO2/NOx in the aqueous phase with production of gypsum and SO2 release in the preliminary scrubbing stage
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/77
Filed: 1985-10-11
Abstract: It is known to separate off SO2 and NOx simultaneously from the flue gas, preferably downstream of power stations, in a single-stage or multiple-stage scrubber. A defined ratio between SO2 and NOx must be present in this case. In particular in the case of slag-tap fired boilers, this ratio of the SO2 load to the NOx load is not present in the flue gas for the wet process. In order to rectify this defect, the feed of SO2 is required, but this is highly complex. To avoid this disadvantage, according to the invention it is proposed that the solid precipitated from the simultaneous scrubber or from the high-grade material recovery stage or from the scrubbing-liquid treatment stage, composed of CaSO3/CaSO4, is fed to the scrubbing-liquid stream of the preliminary scrubbing stage 1 for the oxidation of the CaSO3 quantity by oxygen of the flue gas quantity at a pH of the scrubbing solution of pH 2-2.5.

Title: Method for controlling a rotating blade, in particular a circular-saw blade in a sawing machine, and apparatus for carrying out the method
Inventor: HANSEN JAN MARTIN
IPC: B23D47/00
Filed: 1986-02-04
Abstract: The invention relates to a method and an apparatus for controlling a rotating blade, in particular a circular-saw blade in a sawing machine. To be able, in a two-blade saw, to set the blades very close to one another without limitation of the size of the gap width, it being possible at the same time for a control to be easily adjusted relative to its own saw blade and together with the latter, it is proposed according to the invention that there be provided, to control the rotating blade (1b), a control stop (2b), preferably in the form of an electromagnet (4, 4a), which is mounted on one side of the blade (1b) and allows a fluid layer to be formed between the stop (2b) and the blade (1b). The fluid layer (7) serves, on the one hand, to reduce the friction between control stop (2b) and blade (1b) and acts, on the other hand, as a yielding means for the transmission of a force with which the saw blade (1b) is pushed away from the stop or drawn towards the stop (2b). The air pressure which builds up during the formation of the air layer or of the air cushion (7) is detected by a pressure/current transducer (11) which emits a control signal substantially proportional to the air-cushion pressure, so that the magnet (4, 4a) power is controlled in a manner inversely proportional to the air-cushion pressure (7). <IMAGE>

Title: Low overfall, in particular for rain and melt water
Inventor: GEIGER GERHARD
IPC: E02B7/16
Filed: 1986-04-12
Abstract: In order to prevent the uncontrolled discharge of water in nature, ditches, cuttings and the like must be provided with an appropriate retaining means. The low overfall according to the invention is especially suitable for this. It provides for a specific and, in a certain manner, braked discharge of the water. But on the other hand it holds back stones, branches, earth and the like carried along on the oncoming-flow side. In a preferred and further-developed embodiment, the low overfall essentially consists of a retaining element (1) and at least one, but preferably two or three base plates (2). The retaining element (1) and the base plate (2) are connected to one another via soil anchors (6) which pass through aligned soil apertures (7) and (8) and the free end of which should penetrate as deep as possible into the soil for reliable anchoring. Water can flow over or through the retaining plate (4) of the retaining element (1) either at its top side or through a closable flow aperture. In order to prevent entrained debris, branches and the like from flowing further, a grille screen (20) is put onto the retaining element (1) at the top. Due to the design of the lateral base plate (2) of "double width", two retaining elements in extension of one another can be mounted on one and the same base plate, and a retaining wall can thereby be constructed from several low overflows. This advantageous configuration permits a comparatively small and thus easy-to-manipulate ... Original abstract incomplete. <IMAGE>

Title: Apparatus for removal and fitting of the driving and return drums which are arranged, by means of pedestal bearings, in a drive or return station of a conveyor belt installation
Inventor: BRUECK ALFRED
IPC: B65G23/44
Filed: 1986-08-22
Abstract: The invention relates to an apparatus for removal and fitting of the driving or return drums (7) which are arranged, by means of pedestal bearings (4), in a drive or return station (1) of a conveyor belt installation. A support plate (10) serves as an accessory for the apparatus. It surrounds a section of the periphery of the drum and is supported, so as to be displaceable in the longitudinal direction, upon the brackets (14), which are mounted in the region of the two drum ends, by means of skids (11,12) running parallel to the drum shaft (8). The upper skid (11) serves as a swivelling axis for the support plate (10). In the operating position of the drum (7), when the conveyor belt (9) is untensioned, the support plate (10) can be introduced into the space between the periphery of the drum and the conveyor belt (9). Here it is located in the region of the lower quadrant, which faces away from the pedestal bearings (4) of the drum (7), of the periphery of the drum below the centre of gravity of the drum (7). When the pedestal bearings (4) are disengaged, the support plate (10) and the drum (7) can thus be swivelled about the skid axis (20) by means of lifting devices (28). At the same time, the drum (7) is lifted until it reaches a position in which the drive construction (2) no longer impairs the travel of the drum (7) in the direction of the drum shaft (8) or impedes its removal and fitting. <IMAGE>
