Abstract: The process consists in extracting, in a liquid-liquid extractor 1, the gallium present in a basic solution of sodium aluminate (Bayer liquor) by means of an extractant known under the tradename of Kelex, dissolved in an organic solvent. The organic phase containing the gallium is subjected to a first liquid-liquid extraction 2 by means of an acidic solution to remove, to at least a large extent, aluminium and sodium and then to a second liquid-liquid extraction 3 by means of another acidic solution to recover gallium. This acidic gallium solution is purified by extraction of gallium with an extractant at 4. After the extraction of gallium the acidic solution is recycled to the extractor 2 to reduce the usage of acid in the process. <IMAGE>

Date Oct. 20, 1988.Deposition of a first relatively hard material on a second material that is relatively soft using a rotating rod, bar, tube or other body without translation of the rotating body relative to a workpiece of the second material is achieved by positively cooling the interface between the body and the workpiece such that a shear layer at which heat is being generated moves away from the surface in the direction of the rotating body. On removal of the rotating body from contact with the workpiece, the workpiece is found to be surfaced with material from the rotating body. In a second stage the already deposited material from the rotating body may be cooled by a surrounding body of liquid to enable further material from the rotating body to be deposited on the workpiece. The workpiece may be of plain carbon steel and the rotating body may be of high speed steel or a nickel-based alloy.

Abstract: In the continuous production of non-woven mineral wool, fibre/gas/air mixtures (3, 4) generated by a plurality of unravelling units (14 to 17) are directed, to form a wool lap (25), onto collecting conveyor units (19, 21) having curved suction surfaces (c, d) which are under suction pressure. The arrangement is such that each fibre/gas/air mixture formed by the individual unravelling units (14 to 17) is assigned an imaginary suction surface increasing in size in the conveying direction, specifically d c. It is thereby possible, in a space-saving design, with a constant suction pressure to produce on each collecting conveyor unit mineral-wool laps of rock wool with bulk densities even below 25 kg/m<3> of good product quality. Furthermore, multi-layered felt webs can be formed by connecting a plurality of units in series or by an oscillating deposition of an individual lap. <IMAGE>

Abstract: A method of packaging a beverage containing gas in solution and a beverage package has a chamber 9 in a moulded open topped container 1 (of plastics or metal) in a bottom wall 8 of which is formed a restricted orifice 10. The bottom of the container 1 is received in a cup shaped closure 11 and sealed thereto at 16 to form a chamber 12 which communicates with the chamber 9 through the orifice 10. The chamber 9 is charged with beverage 17 and its headspace 21 is dosed with liquid nitrogen or carbon dioxide prior to sealing with a cap 18 so that the headspace 21 is at a pressure greater than atmospheric. With the sealed package in equilibrium the chamber 12 contains beverage derived from the chamber 9 through the orifice 10 and has a headspace 22. Upon opening of the package by removing the cap 18 and exposing the headspace 21 to atmosphere, the pressure differential between the headspaces 21 and 22 causes beverage and/or gas in the chamber 12 to be ejected through the orifice 10 into the beverage 17 and thereby gas in solution in the beverage to be liberated to form or assist in the formation of a head of froth onthebeverage.

Abstract: Method of contention resolution upon the simultaneous generation, by several local digital interfaces (A, B, C, D, E) able to correspond with one another, of a digital frame (T) on a local bus (LAN). Each digital interface transmits a frame-header contention module which possesses a high-significance fixed part defining a fixed priority and a low-significance variable part. The binary number which corresponds to this variable priority is decremented by one unit after each failure after subsequent collision. By contrast, that of the master passes, after transmission of the frame of this master, to its lowest priority value (all 1). <IMAGE>

Abstract: A process for making plastic siding panels, such as outdoor weatherable vinyl panels with an embossed wood grain pattern, comprises extruding a vinyl sheet, and overlaying on the extruded sheet a flexible carrier sheet having coated thereon (a) matte release layer bonded to the carrier sheet, and (b) decorative coating on the matte release layer facing toward the extruded plastic sheet. An embossing roll applies pressure at elevated temperatures to transfer the decorative coating from the matte release layer and bond it to the extruded sheet, while the embossing roll embosses a three-dimensional impression pattern in the laminate transferred to the extruded sheet. The carrier sheet and its matte release layer are then released from the laminate transferred to the vinyl sheet. The matte release layer transfers a low 75 DEG  gloss level, preferably in the range of 8 to 12 gloss units, while enabling free release of the carrier from the embossed low gloss surface at elevated temperatures. In one embodiment, a multi-layer wood grain printed acrylic/polyvinylidene fluoride blended decorative coating is simultaneously transferred to a vinyl extrusion and embossed with a three dimensional wood grain texture. A color coat behind wood grain print coats contains pigment at a level that protects the vinyl substrate from UV deterioration. The matte release layer contains a suspended wax which enhances forming the low gloss surface while improving release of the matte release layer from the transferred laminate. A silicone resin in the matte release coat combines with the wax to further enhance release properties.
