Title: Improvements in or relating to continuous fermentation process
Inventor: MILLIN DAVID JOHN
IPC: C12G3/08
Filed: 1965-06-18
Abstract: <PICT:1079517/C6-C7/1> In the production of a potable beer there is maintained a circulating body of yeast-containing fermentation medium on one side of a partition and a moving body of wort on the opposite side of the partition, and the partition is essentially porous to permit the passage of the soluble constituents of the wort and for the soluble products resulting from the fermentation of such constituents by the yeast to pass therethrough, but the pore size is sufficiently small to effectively bar the passage of yeast cells. Although the pore size should preferably be below 3 microns to effect total retention of the yeast, it is stated that pore sizes up to 10 microns, which will effectively retain yeast cells up to 7 microns in size, can in some cases be used.  In the simplest procedure Fig. 3 (not shown) hopped wort and a yeast suspension are passed along the opposite sides of a cellulose acetate membrane, or a resin-bonded fibreglass or a sintered plastics filter.  According to a further embodiment Fig. 2 (not shown) yeast-containing fermentation medium is circulated externally of a porous tube (38) of 1-3 microns pore size, or several parallel porous tubes, and brewer's wort is circulated within the tube or tubes from a holding vessel (41).  Referring to the embodiment depicted in Fig. 1, yeast-containing fermentation medium is circulated from a fermentation vessel 1 to the passage 6 between two cellulose nitrate or cellulose acetate membrane filters 8 of 0.3 micron pore size and back to the fermentation vessel by linked variable rate pumps 4 and 5, while fresh wort from a supply tank 12 is pumped under pressure through the left-hand membrane 8 to be carried upwardly by the yeast-containing fermentation medium and a corresponding amount of fermentation medium is displaced through the right hand membrane into a beer receiver 16 from which a proportion of the liquid may be recycled. Carbon dioxide gas is removed from the fermentation vessel 1 by the vortex separator 20 and is collected in a gas holder 21.

Title: Improvement by a new method of manufacturing solid materials by melting or cooling or both while under the influence of centrifugal force
IPC: B22D13/06
Filed: 1937-09-27
Abstract: 502,832. Moulding glass. RUBBISOW G. A. Sept. 27, 1937, Nos. 26118 and 31596. [Class 56] [Also in Groups XXII and VII] A mould, crucible, &c. containing molten metal, alloy, glass, jewel waste or equivalent material, &c. is rotated about an axis which is substantially at right angles to the longitudinal axis of the mould at least until it commences to solidify, for at least 5 seconds or a proportionally longer time if the radial thickness of the material is greater than 1 cm., and at such a speed that the pressure in kg/cm<2> in the interior of the material at a distance of 1 cm. from the inner surface is not less, in numerical value, than one fourth the specific gravity of the material. The treatment may be continued during cooling and if desired during ageing. A mould &c., or a holder 6, Fig. 4, containing one or more moulds 5, may be permanently or adjustably fixed to an arm 2 .rotating about a vertical, inclined, or horizontal axis 1, Fig. 10, or be pivoted at 20 so as to swing into radial position when rotation commences. The weight of the arm may be counterbalanced or a number of such arms may be arranged about one axis. In modifications a number of moulds are arranged on the rim of a wheel or formed as recesses 27, Fig. 11, in a hollow drum 26 for casting lenses free from bubbles &c. and stated to have modified optical properties. The material may be melted and heated during treatment, generally or locally, e.g. to ensure uniform cooling in non-uniform bodies, by gas; electric resistance wires in the wall of the mould, or electrodes 21, 22, Fig. 10, the former being free to move radially and pressed by a spring or weight 35. The mould may be separated from its holder 6 by insulating material 8, Figs. 4 and 10, or may be lined with or made of crushable material to facilitate extraction. Cooling may be accelerated by air currents or by water circulated by the centrifugal action and regulated by the cross-section or radial position of the inlet and outlet or by the pressure in the supply pipe. Rotation may be reversed or shocks or vibrations may be applied to the mould during the process. Centrifugal force may also be applied in two different planes by mounting the mould 5 at the end of an arm 42, Fig. 14, carried by and rotating about the axis of the arm 2. To keep the material molten for suffucient time it may be pre-heated to say a temperature 25 per cent over its melting point in degrees centigrade instead of or as well as heating during centrifuging.

Abstract: 1,128,317. Cables. GENERAL ELECTRIC CO. 14 June, 1966 [22 June, 1965], No. 26381/66. Heading H1A. Insulation for stranded conductors 1 surrounded by paper wrapping 2 comprises a layer 3 of cured polyolefin surrounded by a layer 4 of inorganic fibrous material such as asbestos impregnated with a chlorinated polymeric material. The lifetime of the insulated wire, determined by accelerated heat ageing is greater than that of a wire lacking the impregnated fibrous layer. The polyolefin may be polyethylene, polypropylene, polybutene or polypentene, or a copolymer of ethylene and propylene, butene, pentene, or vinyl acetate, an ethylene-propylene rubber or ethylenepropylene terpolymer rubber. The polyolefin is applied by extrusion and incorporates a cross-linking agent. Alternatively curing is achieved by irradiation. The extruded composition may also contain antioxidants, e.g. hydroquinone ethers, aryl amines, aniline derivatives, wax-formulated polyamines, phenol derivatives, acetone-phenylamine reaction products such as hydroquinolines, and other conventional additives. The asbestos may be applied to the polyolefin layer by means of a carding machine, and impregnated with an organic solution of the chlorinated polymer. The latter may be a chlorinated elastomer, e.g. polyvinyl halides, copolymers of vinyl halides with vinyl acetate or other vinyl esters, or with acrylonitrile, methacrylonitrile or acrylate esters, or with unsaturated dibasic acid esters, or chloroprene rubbers. Posthalogenated preparations may be used, e.g. olefin polymers or copolymers chlorinated or chlorosulphonated after polymerization, or chlorinated natural or synthetic rubbers.

Title: Improvements in and relating to the manufacture of silica glass
IPC: C03B27/06
Filed: 1921-10-06
Abstract: 189,926. British Thomson - Houston Co., Ltd., (General Electric Co.). Oct. 6, 1921. Forming silica-glass articles.-A method of making shaped articles, rod, or tube of transparent silica consists in fusing the silica in a vacuum, cooling it to a congealing temperature, transferring this vacuum-fused silica to a heating space under atmospheric pressure, reheating the silica to a plastic state, and then moulding to a desired form, or extruding through a die, by applying pressure. The silica is first freed from bubbles by melting it in vacuo and subjecting it to pressure in the manner described in Specification 188,451. The resulting mass of glassy silica is transferred to a furnace, shown in Fig. 2, comprising a carbon tube 15, connected to water-cooled terminals 16, 17 by which the heating current is supplied, and surrounded by a packing of charcoal or other heat insulating material in an asbestos receptacle 22. The silica is contained in a graphite crucible 25 situated within the heater and provided with a graphite piston 30, the rod 31 of which is loaded with a weight 32. The crucible has a vent 26 communicating with the surrounding space which is open to atmospheric pressure. The weight on the piston pressing on the plastic silica eliminates bubbles and produces a clear glassy mass. The bottom of the crucible may be fitted with a die so that the silica can be extruded as a rod or cane 40 into a vessel 41 containing water. In making quartz tubing, the bottom of the crucible is provided with a die 44, Fig. 4, having an opening into which fits a tubular core 43 communicating with the atmosphere. Before the furnace is put into operation and before silica is placed therein, the graphite crucible, piston, and die, are fired in vacuo to about 2000 C. Mineral matter is thus volatilised from the crucible and furnace members which come into contact with the silica, and the final product is obtained free from cloudiness or opacity.
