Title: Method for producing high-purity nickel from sulphidic materials
IPC: C01G53/09
Filed: 1972-05-23
Abstract: 1370259 Nickel; ion exchange purification of Ni chloride LE NICKEL 23 May 1972 [24 May 1971] 24282/72 Heading C1A Ni is obtained by drying and roasting a nickel sulphidic material, dissolving in HCl, oxidising the iron content, removing metals other than Ni on a basic quarternary ammonium anion exchange resin, neutralizing the Ni chloride solution, and electrolysing. The ion exchange step is carried out using two sets of resin columns arranged in series, which are each regenerated by rinsing with HCl, eluting with water, and restoring to their original state with Ni chloride solution, the elution solution of the first set being used to elute the second set, then mixed with HCl, purified on a third set of anion-exchange resin columns, and used successively for rinsing the second and then the first set. This solution is then recycled for dissolving more concentrate, together with HCl obtained from the Cl2 evolved in electrolysis. The Ni solution is passed through the first set of columns until Co and Cu begin to appear (this first effluent by-passes the second set); then the Ni solution is passed through both sets until the first set is saturated, when it is regenerated. The pure Ni chloride solution may be neutralized with Na2CO3. The third set may be eluted with water to recover Co, Cu, Zn and Fe. The initial material is obtained by leaching Ni laterite with H2SO4 and precipitating the metals with H2S.

Title: Machine for cutting up lengths of material or substance into sections having approximately a predetermined weight
IPC: A24C5/28
Filed: 1933-09-04
Abstract: 425,114. Cutting and slicing machines. LEGG, 0., 21, Goswell Terrace, Goswell Road, London. Sept. 4, 1933, No. 24467. [Class 5 (i)] [See also Group VIII] In a machine for cutting up lengths of material into sections having approximately a predetermined weight, the speed at which the knife operates is adjustable relatively to the speed at which the material is fed to the knife. An infinitely variable gear is interposed between the feed mechanism and the knife operating -mechanism. A change speed gear effects coarse adjustments of the knife operating mechanism or the feed mechanism. As shown, a number of reels 4 are provided, on which the lengths of material to be out are wound, and from which they pass to an endless band 5 running over a driving pulley 6 and guide pulleys 7. The feed part of the band runs in a channel 8, into which the material is pressed by rollers 9. The pulley 6 is driven through reduction gearing 15, and chain-and-sprocket gearing 16 from a shaft 18 of an infinitely variable speed gear 19, through which the knife operating mechanism is driven. The knife is driven from a shaft 27 through the medium of bevel gearing 20, 21, a universal shaft spring clutch, and chain-and-sprocket gearing. The crank disc 28 is carried by the shaft 27 and is provided with an adjustable crank pin on which is mounted a rod 30 for reciprocating the carriage. The shaft 27 also carries a sprocket 31, driven from a shaft 34, carrying the sliding gears of a change-speed gearing, the driving pinion 37 of which is mounted on a shaft 38, carrying a sprocket 39, adapted to be driven through the infinitely variable gear. When the machine is started the weights cut off by the knife are checked and a hand wheel 42 is operated to alter the speed of the knife relatively to the feed of material. The changespeed gear is adapted for cutting two different lengths of material one being, say, twice that of the other, but any ratio of gear selection may be incorporated.

Title: Fuel injection valves and their manufacture
IPC: F02M61/16
Filed: 1976-06-14
Abstract: 1524436 Fuel injectors L E JOHNSON 14 June 1976 [21 July 1975] 24559/76 Heading F1B [ Also in Division F2] In a fuel injector in which a compression spring 29 holds an injection valve 34 closed, in order to accomodate lateral forces impressed by the spring on the valve, the spring and valve are interconnected by a retainer which allows a rolling motion and which comprises a pin 42 extending through an opening 41 passing through the valve 34 perpendicular to its longitudinal axis, the pin 42 having a lesser radius than the opening 41. Preferably the opening has a double taper 45 producing a narrow bearing area S. In its simplest form (not shown) the retainer comprises only the pin which is flattened at both ends to form surfaces upon which the spring end directly bears. As shown in Fig. 3 there is provided an intermediate collar 44 and guide ring 46. These may be selected of different thicknesses to standardize flow patterns in a set of fuel injectors. The Specification also describes apparatus for measuring the required thickness of collar and/or ring with the spring under a test load, and for measuring the flow of a calibrating liquid through the injector nozzle at full opening. In Fig. 2, an outwardly opening injector is shown, wherein the maximum valve opening is limited by stop face 59 of the guide ring 46 which slides in a body 18. An annular orifice is formed by a conical valve seat 32 co-operating with bulbous member 36, which is shaped so as to centre the valve stem 37 during outward flow of fuel. The body 18 is friction welded to its holder 21 at region 63 and spaced from a filter assembly 67, 68 by a compressible corrugated ring 71. Fig. 6 shows an alternative construction omitting the collar 44, of Fig. 3 wherein the pin 42' has flats 74 bearing on a guidering 46'. The clearances between the valve stem 34' and guide ring 46' are flat on two opposing sides and arcuate on the two intermediate sides and of small dimensions to aid in centring the valve stem 34'. In Fig. 7 such a construction is employed, but the valve travel is limited by a cup 101. A pair of valves are provided; bulbous part 36' co-operating with conical seat 32', and a skirt 97 with a control edge 96. This double valve construction leaves a very small sac space 98 below the lower valve, thus reducing smoke emission from unburnt fuel. An inwardly opening valve 121 is shown in Fig. 10, the stem of which 119 is guided in a cylinder 123 supporting a spring acting - via a ring 46* on a pin 42* on the stem 119. A stop face 109* is machined to an optical finish and serves for introduction of fuel through a bore 136 and as a fuel leak, through bore 134 to cavities 139.

Title: Improvements in or relating to duplicating stencils
Inventor: BLAKE ALAN FRANCIS
IPC: B41N1/24
Filed: 1963-06-21
Abstract: A stencil sheet which can be cut both mechanically and by electric spark comprises a stencil tissue e.g. paper weighing less than 8 gms. per spare metre, and less than 0.0015 inches thick, strengthened with a modified polyamide resin, the tissue carrying on one face a stencil layer of relatively low electrical conductivity loaded with electrically conductive particles and capable of being cut mechanically.  The stencil layer consists of a coating of a nitrocellulose solution plasticized to render it capable of being cut on a typewriter, the coating being made conductive by incorporating therein a highly conductive carbon or metallic particles, or preferably, a higher proportion of a carbon of lower conductivity; in the latter case, the puncturing of the stencil by an electric spark can be arranged so that the void produced is proportional to the applied voltage thus rendering possible the formation of continuous tone originals by facsimile reproduction.  The tissue itself may have incorporated therein a highly conductive carbon, to reduce the electrical resistance of the tissue to that of the stencil layer.

Title: Improvements in or relating to articles consisting essentially of a polymer of tetrafluoroethylene and the manufacture thereof
Inventor: SQUIR ALAN THOMAS BARRINGTON P
IPC: B29C70/34
Filed: 1950-01-26
Abstract: A reinforced thick article is made by spreading evenly in a mould part of the polytetrafluoroethylene powder required to form the article, inserting a layer of reinforcement into the mould, covering the reinforcing layer in part at least with a further spreading of the powder, applying moulding pressure to the charge in the mould to produce a preform, sintering the preform and cooling it.  The Specification defines "thick," which may mean not more than 0.15 inch.  Instead of one layer of reinforcement, several layers may be inserted, powder being introduced after each layer so that there are alternate layers of powder and reinforcement.  The reinforcement may be metal gauze or wire, e.g. of stainless steel or chromium-coated phosphor bronze, and the wires forming one layer may extend in a different direction from the wires forming an adjacent layer or layers.  Part of the reinforcement may project from the surface of the article, thereby making that surface rough, which is useful when the article has to be clamped between two members.  The reinforcement may be only slightly smaller in surface extent than the mould cavity, to avoid distortion of the reinforcement during moulding.  In an example the pressure is built up gradually to 6 tons per sq. inch, the compressed preform is removed from the mould and sintered by heating at increasing temperatures up to 390 DEG C., and the sintered preform is cooled between two cold metal, e.g. aluminium plates or in cold water.  The moulding pressure may be applied to the charge through a rubber sheet.  The Provisional Specification states that electrical conductors may be embedded in the article.
