Patent DE-4228471-A1 (DE)
Inventor: YUEKSEL LEVENT DR
IPC: B01D53/50
Filed: 1992-08-27
Abstract: In the method proposed, the flue gases are scrubbed (3) with a solution containing an alkali. The scrubbing solution is then purified, before or after an oxidation stage (4), in an operation (6) comprising a combination of sedimentation and membrane filtration. At least a part of the solids in the concentrate obtained from the membrane filtration is separated off by sedimentation and the remaining liquid fed back to the membrane-filtration process and hence into the main circuit, and the alkali-metal sulphate crystallized out. A pure-white alkali-metal sulphate free of dark-coloured impurities is thus obtained inexpensively.

Title: Modular roofing for slab constructions
Inventor: GROSMANN HANS DIPL ING
IPC: E04G23/02
Filed: 1993-06-15
Abstract: The object of the invention is to convert flat roofs of slab constructions in East Germany (or elsewhere) to form residential units. Furthermore, a contribution is to be made to helping the environment by reducing the emissions, in contrast with the manufacturing processes which are conventional today. The main factors are the following: Savings in building materials, reduction in structural timber, savings in water and primary energy, and consequently reduction in emissions. The object is achieved by the invention in that the rapid erection of roof dwellings on site is made possible by a standardised module system with a mounting/closure system, appropriate for the standardised slab constructions. The transportable individual modules are erected in external manufacturing workshops as units which are ready for occupation. They are distinguished by a functional link between structural engineering and domestic engineering. The exterior configuration and function of the roof skin can be modified in order to take into account methods, e.g. photovoltaics for retrofitting purposes as well as architectural retrofitting operations and desired alterations. For this purpose, known methods of manufacturing individual elements and domestic engineer are combined to form a new concept. The advantages which can be achieved by the invention consist, in particular, in the fact that existing flat roofs can be rapidly converted into residential units in an environmentally friendly manner.

Title: Radial bearing for an automatic transmission
Inventor: GIESE PETER DIPL ING DR
IPC: F16C33/78
