Title: Method and apparatus for manufacturing mineral wool, and mineral wool produced thereby
Inventor: BATTIGELLI JEAN
IPC: C22C38/00
Filed: 1992-08-03
Granted: 2000-05-30
Abstract: The only methods hitherto available for the production of mineral wool from materials such as basalt either utilize a stationary nozzle (blast drawing method) or external centrifuging whereby unsatisfactory yield and/or a not entirely satisfactory fiber quality, particularly with regard to a high content of unfiberized components, are achieved. By way of the invention, application of a fiberization method is suggested which, in spite of a high fluidity of the molten mineral material such as basalt, arrives at high quality fibers with a low bead proportion at good yield. This is made possible by selection of specific materials and their fiberization in specific conditions. Whereas fiberization of these fluid materials is carried out in external centrifuging at viscosities of a few tens of poises, fiberization by internal centrifuging at viscosities of more than 100 poises is required, according to the invention, in order to achieve a mineral wool for insulation purposes with a low bead content.

Abstract: In a process for the production of aluminum hydroxide involving extraction of alumina from an alumina-containing ore by an aqueous alkaline solution, supplying a slurry containing the alumina-containing ore with a high solid content, which has been prepared from a small amount of an alkaline solution together with an aqueous alkaline solution which is preheated to a temperature that is high enough to have a temperature after the mixing with the slurry that is higher than the extraction temperature of alumina. Simultaneously or after the mixing feedings the mixture to an extraction apparatus comprising a tube reactor, extracting alumina from the alumina-containing ore under conditions of a temperature of 120-160°C and an extraction time within 10 minutes, separating residue from an extract solution immediately after the extraction, desilicating the extract solution, and adding seeds of aluminum hydroxide to the extract solution which is desilicated to precipitate aluminum hydroxide. By this production process, it is possible to economically produce aluminum hydroxide with little contamination by silica from an alumina-containing ore with a high content of reactive silica.

Title: Bidirectional gasket having water energizing pockets
Inventor: WESTHOFF JAMES A
IPC: F16L5/10
Filed: 1994-02-03
Granted: 1997-01-21
Abstract: A molded or extruded bidirectional gasket providing a watertight seal between an opening in a manhole assembly and a pipe extending into the opening, comprises a T-shaped anchoring portion for embedment in a manhole opening.  An A-shaped pipe engagement portion is joined to the anchoring portion by a slender connecting web enabling stretching and bending of the gasket when a pipe  is  inserted.   The connecting web divides the recess into a pair of pockets on opposite sides of the web.   One of the pockets has an opening end which widens to receive water under pressure when the gasket bends to receive a pipe.  The opening of one pocket is enlarged as the other pocket is sealed.  The A-shaped portion has legs providing such recesses.   The gasket apex has a recess to locate voids therein which, in addition to enhancing mechanical softness of the gasket, also provide the ability to alter gasket compression by introducing a liquid filler thereinto.  Tapered projections near the apex wipe the external periphery of a pipe upon insertion and also contribute to the compression of the nose portion of the connector.

Abstract: The object of the invention is an optical fibre of cylindrical construction, providing a lateral light outflow. The optical fibre, which is adapted to convey a light flow from one of its ends, the inlet end (6), to the other end, the outlet end (8), is characterized in that it comprises, at least on a given area (2) of its outer surface, a large number of closely spaced degradations (4) of very small size in relation to the fibre diameter, each of said degradations (4) causing the outflow of conveyed light through the point so that the fibre seems globally illuminated; the surface density of the degradations (4) varies in accordance with the direction of propagation of the light flow, which is thus substantially uniformly discharged over the entire length of the fibre.
