Title: Walls and walkways of reactor building - have intermediate gap filled with flexible pads injected with hardening material esp. cement grout
IPC: E04H9/14
Filed: 1980-12-23
Abstract: A gap between two components, in particular between the inner walls of a reactor safety containment building and horizontal walkways at various levels in a nuclear power plant, is closed with a pressure-resistant structure. A pressurised cushion composed at least partly of flexible material is placed in the gap and expanded with internal pressurising agent to fill the gap and enable forces to be transmitted between the wall and the walkway. In a reactor where the walkways are intentionally located at some distance from the walls to permit the walls to be decontaminated in the case of escape of radioactive steam, this gap must be normally, permanently filled by a thrust-transmitting component so that the walkways are structurally locked to the walls and any vibrations or shocks are transmitted through the gap.

Title: Process for reducing the chemical oxygen demand in the waste waters of flue gas desulphurisation plants
Inventor: WEBER EKKEHARD PROF DR ING
IPC: C02F1/72
Filed: 1981-09-09
Abstract: In the wet flue gas desulphurisation, gypsum is produced which is continuously separated off from the circulating scrubbing liquid. It is unavoidable in this case that the separated gypsum entrains scrubbing liquid, and is therefore contaminated by scrubbing liquid residues. To remove these impurities, the gypsum is washed with water, so that the impurities pass into the waste water of the scrubbing process. These are chiefly non-oxidised sulphite ions or hydrogen sulphite ions and salts thereof, which produce a chemical oxygen demand in the waste water. In addition, the waste waters can also contain organic constituents such as carboxylic or sulphonic acids which are used in the flue gas scrubbing as absorption aids or filtration aids. In order on the one hand to recover these auxiliaries as quantitatively as possible and on the other hand to reduce the chemical oxygen demand to the greatest possible extent, the pH of the waste water is specifically lowered by addition of mineral acids, preferably sulphuric acid. The organic acids pass into the gas phase in this case and can be reused in the desulphurisation process and the components having a chemical oxygen demand are degraded by oxidising agents substantially free from secondary actions, for which, in particular, hydrogen peroxide or peracids or salts thereof are suitable.

Title: Supporting frame of lorries
Inventor: WACKENHUT ERNST
IPC: B62D21/02
Filed: 1981-09-21
Abstract: The invention relates to a supporting frame of lorries, in particular trailers, with a floor which is enclosed by an outer frame, is formed from wood or plastic and is provided, in the vehicle longitudinal direction, with a profiled insert made of steel, light metal or plastic, which supporting frame is supported by profiled side and cross members. The invention is based on the object of improving the supporting frame of this type in such a manner that the weight of the frame, with a low construction, is reduced and, at the same time, the frame is of particularly torsionally yielding design. This is very favourable for a road vehicle because as a result a particular type of spring suspension is achieved. To achieve this object, it is provided that the side members have a Z-profile-like cross section. In its uppermost region, the side member preferably penetrates through the floor support. By this means, the object is achieved and the frame is particularly torsionally yielding. The most varied supports of this type are proposed, it being intended that these be used preferably in the supporting frames of lorries. <IMAGE>
