Patent GB-370978-A (GB)
Title: Improvements in and relating to the removal of carbon oxysulphide from gases
IPC: B01D53/48
Filed: 1931-01-12
Abstract: Carbon oxysulphide is removed from gases by passing the gases in association with hydrogen over a catalyst consisting of cuprous sulphide, tri-potassium phosphate and potassium carbonate, at ordinary pressure and at a temperature between 200 and 250 DEG  C., the carbon oxysulphide being converted into an equivalent quantity of sulphuretted hydrogen which is removed in any known manner.  If the gas contains less than 20 per cent of hydrogen it is preferable to add hydrogen to it before treatment. The catalyst may be supported on an inert carrier such as coal or silica and the cuprous sulphide may be produced in situ by the action of the sulphur containing gases on copper compounds.  The catalyst may be prepared by impregnating wood charcoal with an aqueous solution of phosphoric acid also containing excess of potassium carbonate, and after drying, impregnating the charcoal with ammoniacal copper oxide which may also contain some ammonium carbonate.  After again drying this second impregnation is repeated and after a final drying the catalyst is ready for use. The copper compounds are converted into cuprous sulphide when the sulphur containing gases are passed over it.  A catalyst may also be prepared by kneading coal dust or powdered silica with cuprous sulphide, tripotassium phosphate and potassium carbonate, glucose being used as a binder.  The resulting paste is fashioned into lumps.

Title: Plastic tapes
Inventor: KAIL JOHN ALAN ELLIOT
IPC: D01D5/12
Filed: 1966-01-12
Abstract: 1,129,137. Longitudinally oriented polymeric tapes. IMPERIAL CHEMICAL INDUSTRIES Ltd. 21 Dec., 1966 [12 Jan., 1966], No. 1424/66. Heading B5B. [Also in Divisions D1 and D2] Longitudinally oriented tapes comprising one or more layers of crystalline synthetic organic polymeric material are produced by extruding the material in the form of a tape (or preferably extruding the material in the form of a wide film and slitting the film longitudinally to form a number of tapes), heating the tape to a temperature at which it will draw uniformly but below its melting point, drawing it to at least 5 times its original length, quenching it to room temperature and allowing it to relax by at least 5% of its drawn length while under a longitudinal tension of from 100 to 5000 p.s.i. The tape may be stretched by passing it from at least one contacting roller surface rotating at a given peripheral speed through a zone in which it is heated to a temperature at which it will draw uniformly to at least one following contacting roller surface rotating at an appropriately higher peripheral speed and maintained at such a temperature that the drawn tape is cooled to room temperature. The drawn tape is then, while still at room temperature, passed to at least one further contacting roller surface at such a distance from the previous roller surface that the drawn tape is allowed to relax by at least 5% while under a longitudinal tension of from 500 to 5000 p.s.i. The distance between the point at which the tape reaches the drawing temperature and the second contacting roller surface may be relatively short. The heating of the tape in the drawing zone may be adjustable so that the heat supplied to the upper side of the tape may be greater or less than the heat supplied to the lower side of the tape. The tape may be folded longitudinally either before or after it is drawn. The wide film or the tape may be formed by melt extrusion. The polymer extruded may be polypropylene, polyethylene, polyoxymethylene or a polyester. Two polymers the optimum drawing temperatures of which are within 25‹ C. of each other may be extruded together. The two polymers may be polypropylene and high density polyethylene. The extruded film or tape may comprise a layer of extruded crystalline polymeric organic material coated on one or both sides with a layer of a heat sealable polymer, e.g. by coextrusion. The crystalline polymeric organic material may be polypropylene and the heat sealable polymer may be a low density polyethylene. If the film or tape is formed by melt extruding polypropylene, the tape may be drawn at a draw ratio of 7 to 13. and may be allowed to relax for at least 2À4 seconds. Woven articles such as sacks may be made from the tapes of the invention (see Heading D1K).

Title: Improvements in and relating to turbines and like machines
IPC: F01D5/14
Filed: 1957-01-16
Abstract: 851,524. Boundary layer control. SHEETS, H. E. Jan. 16, 1957 [Jan. 16, 1956], No. 1623/57. Class 4. [Also in Group XXVI] A turbine or blower blade of aerofoil section has a slot extending longitudinally of the blade and opening into the low pressure face of the blade along a line between the forward and rearward lines of maximum frictional intensity on that face. Frictional intensity is defined as the product of the viscosity of the medium involved and the velocity gradient in the boundary layer adjacent the surface. Preferably the slot opens into the face along a line located in the transitional region between laminar flow and turbulent flow. The slot may open into the high pressure face along a line rearward of the forward line of maximum frictional intensity on that face. In the Figure, the slot divides the blade, of chord c, into leading and trailing aerofoil-section portions. Flow takes place in the slot from the high pressure to the low pressure side, and the entry width m of the slot should be greater than the exit width s, the latter being between one half and five per cent. of the overall chord c. Similar limits are given for the length o of the slot. The slot may be located at 60 to 70% of the chord from the leading edge. The maximum distance n y  of the mean camber line from the chord line should be at a station n x  near the rear part of the leading portion. The angle #F between the chord line c<SP>1</SP> of the leading portion and the overall chord line should be smaller than the angle #R<SP>1</SP> between the line joining the trailing edges of the two portions and the overall chord line. The angle between the trailing edge of the high pressure surface of the forward portion and the chord line of that portion should be greater than the angle formed between the tangent to the lower pressure surface of the rearward portion at the slot exit and the chord line of the forward portion. The camber angle # of the blade should increase from tip to root. The angle # between the chord lines of the two portions should also increase from tip to root. The two portions may be connected across the slot by a stay of small radial dimension. The slot may be formed in rotor or stator blades. U.S.A. Specification 2,314,572 is referred to.

Abstract: 1361266 Animal feeds; preserving crops ELTSAC FEEDS Ltd 29 Dec 1972 [30 Sept 1971 14 Jan 1972] 45644/71 and 1819/72 Headings A1F A2B and A2D An animal feed is made by reacting a sugar containing product with calcium oxide or hydroxide, to form a product which solidifies and may be moulded into bricks or cakes or formed into meal. The sugar-containing product is molasses, root crops (e.g. swedes, mangolds, or fodder beet), sugar cane, bananas, grass, sugar beet pulp, or sugar beet tops. Alternatively the sugar may be produced from potato starch by treating finely divided potatoes with diastase (e.g. malt extract) at about 37C. The weight ratio of sugar-containing product to calcium hydroxide or oxide is greater than 8:1. The molasses is used at or near its boiling point, being heated either separately, or together with the other ingredients. A roughage source (e.g. bagasse, brewers or distillers grains, or wet straw processed with caustic soda) may also be included. Other named ingredients are urea, barley meal, herring meal, extracted groundnut meal, hay, salt, and wheat feed. When reacted with the sugar in grass, calcium compound acts as a desiccant and inhibits fermentation and mould. A proprietry livestock mineral mix may be included to form a lick or mineral block.

Title: Device for supplying gas to a liquid and stirring the liquid
Inventor: FUCHS HUBERT
IPC: C02F3/20
Filed: 1975-01-15
Abstract: 1462005 Stirring and supplying gas to liquid ALFA LAVAL AB 15 Jan 1975 [23 Jan 1974] 1829/75 Heading B1C A device for stirring and supplying gas to liquid, e.g. for use in aerating organic substance containing waste waters, precipitating divalent iron from water by oxidation to trivalent iron, or removing carbonic acid from steam boiler water by aeration, comprises a hollow rotary shaft 5 having a free end open at 7 and carrying one or more helical impeller vanes 9 each extending at least two thirds of the shaft circumference and each having, in addition to its helical inclination, at least a part of its surface inclined to the shaft axis towards the free end of the shaft, said vanes in use of the apparatus, being immersed in the liquid thereby stirring the latter, producing a liquid flow to suck air from the interior of the hollow shaft for mixture with the liquid, and avoiding undesired sedimentation and formation of stagnant liquid zones. The axial pitch of the vanes may decrease towards the shaft free end to accelerate liquid movement by decreasing intervane space. As shown, the hollow shaft 5, together with a driving motor 3 and a position adjusting lever 4 therefor, is universally mounted by a cardan joint 2 on a stationary beam 1. The shaft has air inlet openings 6 disposed, in use, above the liquid level, a foam breaking-up knife 8, and, if desired, a splash guard disc (not shown) disposed below the openings 6. The knife 8 preferably has trailing spiral arms (Fig. 14, not shown), to avoid sticking of solids thereto, and said arms may have screw inclination (Fig. 15, not shown) to suck up foam for breaking up. Two diametrically opposite helical vanes 9 are provided at the shaft free end and each vane makes about one full turn. In Figs. 3, 4, 7 (not shown), the vanes are turned down slightly at their outer edges. In Fig. 3 (not shown), the vanes are of constant radius, whereas in Figs. 4-7 (not shown), to prevent sticking of solids to the vane inlet edges, the vane radius increases from zero towards the shaft free end. In Fig. 5 (not shown), the shaft free end opening is flared to increase suction. In Fig. 6 (not shown), the vanes extend beyond the shaft free end as fins. In Fig. 7 (not shown), the shaft free end is flared and extends beyond the vanes, an optimum effect being obtained when said extension beyond the vanes equals half the wavelength of the waveform liquid flow. In Figs. 8, 9 (not shown), the shaft has an additional outlet opening disposed between two vanes which opening is shielded by a part cut out from the shaft wall and in trailing tangential relationship thereto to engender air suction. In Fig. 10 (not shown), the shaft outlet is S-shaped. In Figs. 11-13 (not shown), three vanes are of increasing radius towards the shaft free end, the outer edge of each vane is turned down, and, to prevent sticking of the solids and increase liquid flow velocity, the said outer edge is concavely joined to the surface of an adjacent vane.

Title: Improvements in or relating to methods of manufacturing cellular products
IPC: C08J9/06
Filed: 1951-01-24
Abstract: A synthetic resinous material is given a polyhedral cellular structure by admixing at least two constituents each consisting of a fine dispersion in an inert carrier of a substance capable of reacting with the substance or substances in the one or more other constituents to generate a gas to expand the resin.  Suitable inert carriers are starch, synthetic resins, e.g. polyvinyl chloride or polystyrene, and solvents and plasticizers, e.g. dibutyl phthalate. A reaction constituent may be mixed in the form of a solution in the case of a solid carrier, the solvent being subsequently drawn off. In the examples: 1 (a) sodium nitrite dissolved in ethanol/water is homogenized with polyvinyl chloride, the mixture dried and comminuted; (b) ammonium sulphate dissolved in 0.1 per cent. aqueous soap solution is mixed with powdered polyvinyl chloride and the mixture dried and comminuted. Equal amounts of the two ingredients (a) and (b) are mixed together with dibutyl phthalate as plasticizer and moulded as described in Specifications 652,696 and 660,358.  In example 2, the reacting constituents are ammonium nitrate in polystyrene, and sodium nitrite in polyvinyl chloride, and are used for expanding a mixture of rubber and polyvinyl chloride.  In example 3, ammonium bicarbonate and amyl nitrite, both in dibutyl phthalate, are used with polyvinyl chloride.

Abstract: 1320883 Washing and sterilizing apparatus SYBRON CORP 14 Jan 1972 [25 Jan 1971] 1886/72 Heading A4F [Also in Division A5] Articles, e.g. bed-pans, trays, dishes, etc, in chamber 8, are washed and rinsed by water from a reservoir 20, and then sterilized by steam, steam also being used to heat the water in the reservoir 20 via line 58. When the temperature of the water reaches that required for the wash cycle, as controlled by temperature sensor TS-2, a pump 28 fills the chamber 8, a second pump 46 then cycling the water, plus detergent from tank 38, until a time delay relay TDR-1 initiates draining through lines 52, 86. Rinsing, at a higher water temperature controlled by sensor TS-3, is facilitated by a pulse motor which intermittently activates the pump 28, the water being constantly drained from the chamber 8. During the following sterilizing cycle, all the steam from line 56 is directed to the chamber 8, condensate being drawn therefrom by opening solenoid valve SV-9 and activating water ejector 74. After sterilization, the steam in chamber 8 is condensed by passing water through coil 80 thereby causing a partial vacuum which activates vacuum switch VS-1 and initiates the venting of the chamber 8. Steam activated gaskets 64, 66 and valve V5 are opened to the atmosphere releasing the partial vacuum in chamber 8 allowing the removal of the articles on conveyer 18.
