Filed: 1938-10-18
Abstract: 519,473. Concentrating gold-bearing ores, &c. NEVILL, P. W. Oct. 18, 1938, No. 30094. Convention date, July 18. [Class 82 (ii)] Gold is concentrated from acid pulps of goldbearing ores, slimes, residues &c. by subjecting the pulp to treatment with acetylene in the presence of a soluble copper compound and then to froth flotation. The soluble copper compound may be present as such in the ore &c. may be derived from a copper compound in the ore by addition of acid, or may be added to the pulp. According to one example a gold ore was crushed and pulped, and after addition of copper sulphate and common salt the pulp was agitated with acetylene gas, oiled, and subjected to flotation, using acetylene to form the froth. In another case copper sulphate, ferrous sulphate, and common salt were added to the pulp which was then agitated, aerated first,with air and then with acetylene gas, oiled, and floated. In a further example after addition of copper sulphate the pulp was agitated with aeration in a closed container ; calcium carbide was then added to liberate acetylene and the pulp again agitated. It was then subjected to froth flotation.

Title: Methods of producing thin strips of material on a supporting surface
IPC: H01J29/08
Filed: 1937-11-03
Abstract: 505,183. Resistance coatings and deposits. HOLMAN, H. E. Nov. 3, 1937, Nos. 30112/37, 33433/37, and 23730/38. Drawings to Specification. [Class 37] [Also in Groups XV, XX, and XL) A non-inductive resistance, e.g. for a photoelectric device where a light-sensitive substance is required to have a low transverse resistance, is produced by applying a layer of material such as varnish to a surface, engraving the layer to expose parts of the surface, coating the engraved layer, and then treating it to cause it to expand or swell whereby the coating is broken along the edges of the exposed areas and the parts of the coating outside those areas may be removed. A single groove may be traced by means of parallel lines, or alternate lines of a series of parallel lines may be connected to a common conductor. In an example for producing fine metallic lines on a glass plate, the plate is coated with cellulose acetate varnish, spaced lines are formed in the layer by means of a ruling machine using a prismatic cutter freely movable in a vertical plane to follow irregularities in the contour of curved work, and a metal coating is applied by evaporation of metals such as platinum or tungsten heated in vacuo, by anodic bombardment or sputtering, or by electrolysis. The plate is then immersed in acetone whereby the varnish expands and breaks away the overlying metal and allows it to be removed: the plate may then be heated to burn the metal lines into the surface. A mat surface may be produced on the plate by etching before or after applying the layer. The lines may be formed in the varnish layer photographically by applying bichromated glue or gum, exposing to light through a stencil, washing away the unexposed parts, dissolving the corresponding parts of the layer and removing the remaining glue. Specifications 381,306, 454,937, 455,123, [all in Group XL], 480,918; and 500,805, [Group XL], are referred to. Reference has been directed by the Comptroller to Specification 294,987, [Class 198 (ii)]

Filed: 1971-06-29
Abstract: 1350244 Knitting machines FOUQUET-WERK FRAUZ & PLANCK 29 June 1971 [2 July 1970] 30315/71 Heading D1C In a circular multifeed knitting machine, a selector cylinder 13 coaxial with the needle carrier 1 carries selector jacks 16 coupled to needle control means 10, at least some jacks 16 having selectively movable elements 27 at different levels, all elements 27 being selected by a pattern carrier 80 at a selection position and respectively acted on by cam means 32, 33, 34, 35, 36, 37 at each of the knitting stations so as to move selected jacks and hence their associated needles between idling and knitting position, erase means being provided for returning the elements to their unselected position. A jack 3 is pivoted to each needle 2 and is swingable between a non-knitting position engaging a groove 4 and a knitting position with its butt 5 engaging cam track 6. Needles 2 have butts 8 to engage a cam track 7. The lower ends of jacks 3 are engaged between abutments 11 on members 10 which are guided in tricks in a disc 12 carried on a cylinder 13 mounted on drive ring 14 which rotates with cylinder 1. Members 16 longitudinally slidable in grooves in cylinder 13 are held by ring spring 18 and by cam parts 19. Cam parts 20, 21 at each knitting station are aligned with the jacks respectively in their lifted and lower positions and when pushed in cause these aligned jacks to be pushed in to make their associated needles are inoperative. Jacks 3 and members 10 are restored to normal position by cam 22. Pins 27 slide in grooves 26 in jacks 16 and are held by crosspiece 28 being associated with ring grooves in cylinder 13 having slanting lower edges 29. Butts 16" on members 16 co-operate with cam 30 which, before reselection pulls members 16 down so that pins 27 are pushed back to unselected position. Slidable members 32-37 aligned with pins 27 are each associated with a different knitting station and select their aligned pins 27 according to the pattern already selected to be knitted at that station e.g. by a band or tape 80 carried on a drum whose axis is parallel to that of cylinder 13 and which is driven in synchronism therewith. The tape 80 has tracks 32'-37' with holes corresponding to the pattern there being grooves in the drum so that pins 27 can pass through these holes and remain undisturbed. Pins engaging parts of the tape without holes are moved forward so that they are not engaged by their associated cams 32-37. Jacks 16 without pins 27 have pins 38 lifted by associated jack lifters 38' at knitting stations and these needles are not selected for patterning selection for interlock, 1:1 and 1:2 rib knitting is possible. This patterning arrangement can be used on the dial of a cylinder and dial knitting machine. In another arrangement Fig. 7 (not shown) pairs of pins are used so as to double the patterning possibilities for a given number of levels.

Title: A process for refining vegetable protein
IPC: B01J47/00
Filed: 1960-09-05
Abstract: Vegetable protein is refined from vegetable seeds from which at least part of the oil has been removed by treating the seeds with water in the presence of an anion exchange resin to extract soluble protein, separating the solution of the protein from the extraction residue and thereafter separating the protein from the solution.  The anion exchange resin may be washed with caustic soda solution followed, optionally by washing with water, the washings being subsequently treated with a cation exchange resin to remove sodium ions and so obtain a solution containing organic acids originally present in the vegetable seeds.  Examples of seeds are soybeans, peanuts, cotton, kapok, sunflower, rape and sesame seeds.  The solution of the protein may be treated with a cation exchange resin and neutralized to pH 7.0, prior to adjusting the pH to that of the isoelectric point of the protein to precipitate the protein.  Alternatively, the pH of the solution of the protein may be adjusted to the isoelectric point without prior treatment with the cation exchange resin.
