Patent DE-3712679-A1 (DE)
Title: Process for preparing calcium sulphate dihydrate
Inventor: GEBHARD GEORG DR RER NAT
IPC: B01D53/50
Filed: 1987-04-14
Abstract: The invention relates to a process for preparing flue gas gypsum in the course of the flue gas desulphurisation of power station boiler furnaces, in which the flue gas is treated in a scrubbing tower with a scrub water suspension containing lime or limestone and the sulphur dioxide thus scrubbed out is converted in the bottom of the scrubbing tower, with feeding of atmospheric oxygen, by oxidation and by crystallisation into calcium sulphate dihydrate crystals. A circulating stream is drawn off from the bottom of the scrubbing tower and is fed via atomisation nozzles to the scrubbing tower. A further crystal suspension stream is continuously drawn off from the bottom of the scrubbing tower, fed to a cyclone separator and after separating off crystal slurry is recirculated to the bottom of the scrubbing tower. The material flowing from the bottom of the cyclone separator and carrying the crystal slurry is dewatered, flue gas gypsum is drawn off and the clear liquid is fed to the scrubbing tower. According to the teaching of the main patent, the proportion of fines in the bottom of the scrubbing tower is adjusted such that at least 10% by weight, preferably from 20 to 70% by weight, of the solids carried along in the crystal suspension stream remain in the material flowing from the top of the cyclone separator. In further embodiment and improvement of the process known from the main patent, lime or limestone in the form of a siliceous power station effluent treatment sludge having a pH between 8 and 10 is fed to the scrubbing tower. <IMAGE>
Patent DE-3718040-A1 (DE)
Inventor: FRANK WILHELM
IPC: E05F1/10
Filed: 1987-05-28
Abstract: A skylight, having a wing actuated by pneumatic springs, can be moved to an emergency opening position thereby substantially exposing the opening area of the skylight case. The skylight also acts as a residential ceiling or attic skylight which has, in the normal open position, a considerably smaller opening than in the emergency open position. A locking device is provided to restrict the long extension stroke of the piston rod of the pneumatic springs to a partial stroke. This partial stroke allows an opening which essentially corresponds to the standard opening of the wing in a residential skylight. The locking device, located on the cylinder of the pneumatic spring, includes a specially designed latch which, in order to effect partial stroke restriction of the piston rod, lockingly engages a stop located on the side of the case by means of a catch pin.

Title: Electrical apparatus having a rocker key (tumbler key)
Inventor: CRAMER CONRAD
IPC: H01H23/14
Filed: 1987-06-13
Abstract: An electrical apparatus contains a rocker key (1) which operates two contact bellows (4, 5) of a contact mat (6), as a function of its tilted position. The rocker key is mounted by means of mounting pins (7, 8, 9), which are fitted to the key ends (20, 21), in mounting incisions (10) in the walls (11, 12) of the apparatus. The mounting pins are aligned in two tilting axes (23, 24) of which that tilting axis which is furthest away from the operating point always acts, thus producing an offset of the operated contact bellows (5) which is at worst not disturbing. <IMAGE>

Inventor: FABRITZ GERHARD
IPC: A63C19/00
Filed: 1987-07-01
Abstract: The invention relates to a roofing for open spaces, for example garden restaurants, tennis courts, storage areas, etc. In the case of this roofing, rails 1 profiled in a U-shaped manner are, in accordance with Figures 1 and 2, displaceably mounted on cables 3, braced in a known manner between masts 2, in that corresponding bores are provided in the rails. The leg ends of the rails merge into rolled-over portions 4 which are directed outwards in a tubular manner. The sides, merging into tubes, of sheets 5 are drawn through in each case two mutually opposite rolled-over portions, wires, preferably consisting of soft plastic, being drawn through the tubes. The roofing is opened and closed by means of pulling cables 6 which are fastened on the rails 1' at 10 and can be moved back and forth via driven shafts 13, rollers 7 and guide pulleys 8. On opening, the rail 1' carries along all the other rails with it one after the other, all the sheets 5 assuming a downwardly directed position in accordance with the chain-dotted line 5'. On closing, the rail 1' draws all the other rails along with it via the sheets 5, which then give the roofing shown in Figures 1 and 2. The rail 11 is fastened fixedly on the mast 2', and eyelets 12 in which the pulling cables 6 are guided are provided on the other rails 1. Fastened at the ends of the rails 1 are stabilising cables 14 which can be anchored in the ground at 15 and ... the roofing at ... Original abstract incomplete. <IMAGE>

Title: Method for controlling a heating installation
Inventor: KLEIN RUDOLF
IPC: F24D19/10
Filed: 1988-06-16
Abstract: Heating installations having a plurality of boiler stages (1, 2) capable of being switched into the heating-water circuit possess, in a common flow pipe (5), a temperature sensor (11) which acts on a cascade connection (10). In order to avoid undesired switching of the cascade connection (10) when the boiler stage (2) is switched off, the temperature sensor (11) is switched by the cascade connection (10) to a 3-level controller (12) which influences the remaining flow element (3).

Patent DE-3823837-A1 (DE)
Title: Method for the production of groundwood
Inventor: BARNSCHEIDT WOLFGANG DIPL ING
IPC: D21B1/18
Filed: 1988-07-14
Abstract: The production of groundwood is usually carried out by means of grinder stones (1) with the addition of spray water, the wood logs being ground to a groundwood suspension which is drawn off from the grinder, sorted and/or refined. Independently of whether press-grinders (18) or continuous grinders (17) are used, which can be designed as encapsulated pressure grinders or as grinders which work at normal atmospheric pressure, the question of the temperature of the grinder stone surface is decisive for the quality of the groundwood produced. The temperature of the grinder stone surface is held beneath the boiling point region, the temperature difference between grinding zone and regions outside the grinding zone being simultaneously held at a value between 5 and 20@C. <IMAGE>
