Patent DE-3816571-A1 (DE)
Inventor: HAUPT HANS JUERGEN DIPL CHEM D
IPC: C04B35/00
Filed: 1988-05-14
Abstract: In a process for the production of refractory mouldings based on dead-burnt dolomite and/or dead-burnt lime, even with enrichment by magnesium oxide, and with addition of a carbon-containing binder in amounts by weight of up to 6%, and a further addition of carbon in amounts by weight of from 0 to 20%, the advantages of high-temperature conditioning are utilised, but the loss of carbon is avoided and the shelf life of the refractory mouldings obtained is increased. This is achieved by subjecting mouldings to heat treatment up to 800 DEG C in a furnace whose atmosphere contains < 2% by volume of oxygen and > 8% by volume of carbon dioxide (CO2). Basic, refractory mouldings are obtained which emit virtually no smoke on heating when used in metallurgical vessels, in particular pans for steel treatment.
Patent DE-3818579-A1 (DE)
Title: Separator for floating and/or suspended matter
Inventor: DAUM WILFRIED DIPL ING
IPC: B01D21/00
Filed: 1988-06-01
Abstract: There are separators of cylindrical shape of the type lying longitudinally and of the vertical type. An increase in the nominal size can take place only by an enlargement of diameter, but this is limited by the dimensions for HGV transport. According to the invention, inflows and flow-offs are now placed on the curved walls, so that the flow passes through the cylindrical container transversely to the axis. The scum board or overflow wall is located at the lowest vertex, so that one inspection shaft is sufficient.

Patent DE-3832773-A1 (DE)
Inventor: NEUHOLD HEIMO
IPC: B28B3/12
Filed: 1988-09-27
Abstract: The invention relates to a process and a device for producing mineral-fibre boards (3), in which, following a thickness precompression in a prepress (4), a longitudinal compression is performed by bulging out of the mineral fibre layer (3) in several successively arranged compression stages (8 to 11) up to entry into the tunnel oven (5). This achieves the effect of a gradual longitudinal compression, which results in a very uniform and lasting alignment of the fibres within the layer (3). This in turn increases to a considerable extent the compressive strength and abrasion resistance of the end product. <IMAGE>

Title: Special self-tapping hanging and standing device for the beer barrel
Inventor: MACK HEINZ
IPC: B67D1/06
Filed: 1988-10-26
Abstract: The invention is mainly characterised in that a unit or a device hangs on the wall and can be fastened to the wall panelling by means of 2 or 3 slotted fastening plates and in that a moveable supporting panel can be made to adopt a 20@ tapping position, so that the last glass of beer can still be tapped without tilting the beer barrel. A beer barrel with a capacity of between 10 litres and about 25 litres can be hung on the wall on this device. The table remains free for other items of use to customers. A beer barrel hanging from the wall is jointly purchased and drunk by a small group of customers who gather round it. Thus small groups are formed, the conviviality is encouraged and there are no charging problems, as fixed quantities are sold in advance, instead of each glass of beer being individually sold by the staff, as usual. No time is spent waiting and the staff can devote more attention to customers and other services, leading to an increase in sales. Beer has hitherto been tapped from a large beer barrel into beer glasses, in which it is sold in individual portions by the staff, the central point being the bar and the tap, which will remain the case for the customers gathering around the bar. Only the customers at tables or seated or standing in alcoves are served by the staff and generally have to wait longer for their beer. This device causes the central point to be split into a number of different points for small groups of customers, who jointly purchase a barrel of beer, the latter hanging on the wall for the group of customers to tap themselves, and having a ...

Title: Fluid-flow engines having an adjustable contouring (shaping) grating (grid)
Inventor: FREUDENAU GUENTER
IPC: F03D7/06
Filed: 1989-01-07
Abstract: In order to reduce the flow resistance of the counter-rotating end of a rotor, use is made of a special form of a profile configuration flow attack surface on which the lift chiefly acts. It consists chiefly of a grating which can rotate about an axis and at least 1 flap which bears against the grating as determined by the flow and in accordance with phase. The grating (adjustability provided) dictates the profile configuration of the flap. The principle is: the contouring grating/hinge/flap system can be configured diversely and can be extended. A device is provided in order to achieve relative storm fitness. A fluid-flow engine according to the principle can be set up using the simplest of means.
Patent DE-3901920-A1 (DE)
Title: Apparatus for high-pressure injection
Inventor: TUTTASS EDMOND ING GRAD
IPC: B09B1/00
Filed: 1989-01-24
Abstract: By means of this apparatus and the high static pressure of a free-flowing substance of high density, the earth material can be forced open at great depths and then free-flowing materials, preferably substances to be disposed of, can be injected at great earth depths by means of the apparatus according to the invention. The apparatus consists of one or more high-pressure vessels into which the respective substances, e.g. radioactive waste, are alternately fed under low pressure and then are injected in each case under high pressure through a borehole at great earth depths and are, for example, permanently disposed of. Shut-off members and non-return stop valves permit the alternation in the low-pressure feeding and the high-pressure emptying of the injection pressure vessels. Three injection pressure vessels enable material to be injected continuously into the earth. Diaphragms in the pressure vessels and a sealing liquid separate if need be the surface pump circulation liquid from the free-flowing material to be disposed of. The apparatus according to the invention is also suitable for injecting water at great earth depths for extracting terrestrial heat or for crude-oil or natural-gas displacement, if need be with effluent disposal. Furthermore, the apparatus also serves to inject any material under high pressure, e.g. construction materials for the consolidation or pressure moulding, e.g cold working, of waste or earth substances to form building blocks or construction elements.
