Title: Concrete shuttering with high easily calculated stress resistance - employs hinged couplings connected to cross members with screw fittings
IPC: E04G11/06
Filed: 1976-07-24
Abstract: Concrete shuttering can absorb a high degree of stress exerted in the longitudinal plane of the couplings. It is also possible to calculate easily and exactly the amount of stress which can be absorbed, eliminating the need for allowing large safety margins. The couplings (10) can be progressively attached be progressively attached to the crosspieces (7, 8) of adjacent shuttering elements using screw mechanisms which cooperate with the crosspieces because of an association of forms in the longitudinal direction of the crosspieces. The coupling itself is split into two coupling bars (12) hinged together at a pivot (11) with a screw mechanism attached to one of the bars. The screw mechanism is inserted into the holes in the crosspiece and the coupling and tightened to prevent movement.

Inventor: OERTLE RUDOLF
IPC: H04J3/02
Filed: 1977-02-09
Abstract: In order to avoid all of the equipment needing to be manufactured from expensive heat-resistant material, in this process, the exhaust gases are first passed through an inlet port (1) directly into an immersed tube (2), which is cooled on all sides by a cooling medium. The cooling and scrubbing medium, which is enriched with corrosive substances, in the bottom part (3) of the equipment, which bottom part is filled with this medium up to an outlet port (9) configured as a siphon, is continuously withdrawn and replaced by feed of fresh medium, which passes through a port (11) into the trickling chambers (4, 5). The purified exhaust gases leave the equipment via a liquid separator (8) through an outlet port (7). The immersed tube (2), with respect to the corrosive, gaseous substances, is composed of corrosion- and heat-resistant material, for example quartz glass or fused silica, and the remaining parts of the equipment are composed of cheaper plastic, corrosion-resistant with respect to the corrosive, gaseous substances. The process and the equipment are suitable for example for freeing hot exhaust gases from hydrogen chloride or sulphur dioxide. <IMAGE>
