Patent GB-873487-A (GB)
Title: Method for the casting of fusible metals
IPC: B22C23/02
Filed: 1957-12-18
Abstract: 873,487. Casting processes. FROMSON, H. A. Dec. 18, 1957 [Dec. 20, 1956; July 10, 1957], No. 39408/57. Class 83 (1). Metals are cast in contact with a solid layer of a retaining material having low thermal conductivity and a melting-point lower than that of the metal being cast, which retaining material layer is supported by the surface of a backing material having a high thermal conductivity and absorbing heat from the melt through the retaining layer until the melt is at least partially solidified, while keeping at least a continuous film of the retaining material and all of the backing material in a solid state. The mould backing may have a melting-point below that of the material being cast and be for example Cu and its alloys, A1 and its alloys, Ag and its alloys, steel and graphite. The retaining surface material may be inorganic salts and mixtures thereof, and inorganic oxides and mixtures thereof. Examples of salts are those tabulated in Specification 769,128. The backing material may be cooled by a circulating coolant or it may rely on its mass to achieve the desired cooling effect, and there are equations given which are used to determine the practicability of particular combinations of material, weight of metal which may be cast in a particular mould &c. The tendency to superficial melting of the retaining layer keeps the casting in good thermal contact with the mould, avoids the formation of air gaps between casting and mould, permits ready removal of the casing from the mould surface and avoids wear of the solid backing of the mould. The retaining layer is usually renewed prior to each casting operation. It may also be fused after the casting is formed, by the residual heat of the casting, allowing easy removal of the casting, particularly when this is cast around the mould as in the production of seamless tubing. In one example steel slab one inch thick is continuously cast at one square foot per minute in a mould comprising a watercooled copper bottom 0.25 inches thick, with a solid retaining layer of barium chloride on the upper surface, on which is superimposed fused barium chloride maintained at its melting- point of 1760‹ F. The molten steel is solidified in a layer moving across the surface of the solid barium chloride and under the fused barium chloride, which latter prevents oxidation of the casting.

Abstract: 1,116,303. Making coiled wire by winding; endless conveyers. WHITNEY BLAKE CO. 15 Sept., 1965, No. 39480/65. Headings B8A, B8G and B8S. [Also in Divisions B3 and H1] Apparatus for imparting a coiled configuration to a cord such as plastic coated wire, comprising at least one mandrel upon which a cord may be wound, having holding means for attaching one end of the cord to the mandrel and a cord guide mounted on the mandrel so as to slide and rotate relative thereto and means for rotating the mandrel whilst preventing the cord guide from rotating therewith, whereby the cord is helically coiled in successive turns about said mandrel during rotation thereof. Mandrels 12 each having a plastic coated wire length W, clamped at one end by means 74 to the mandrel 12 and threaded through a guide 76 slidable on the mandrel, are released one at a time from a hopper 10 by means of a pivoted finger 36 rocked by a cam-operated lever 22. Each loaded mandrel is deposited on a saddle 44 on an endless conveyer 46 which carries the mandrel 12 along, with its ends 50, 52 rolling on an overlying magnetic track 58. Consequent rotation of the mandrel 12 causes the wire W to be coiled therearound the guide 76 being prevented from rotating by its sliding engagement with a table 90 on the saddle 44. The wound mandrel is transferred from the saddle 44 on to a lower conveyer 106 by notched wheels 96, rotation of the guide 76 in the uncoiling direction being prevented by a helical coil spring (88), Figs. 9, 10 (not shown), tightly surrounding the mandrel and secured at one end to the guide 76. The conveyer 106 carries the wound mandrels beneath heating means 104 which serve to set the insulation coating, which may be neoprene, on the wire thus to retain the helical form of the wire, the mandrels being rotated by engagement with a friction shoe 112. The wound mandrels then drip on to a cooling zone conveyer 114 and pass therefrom on to a discharge conveyer 120, cooling air being provided by a fan 128. The coiled wire is removed from its mandrel 12 by being reversely coiled on to a further mandrel 158, Fig. 11, to reverse the angle of pitch.

Abstract: 1,014,209. Pneumatic despatch apparatus. G. NIEMOLLER, Sept. 28, 1964 [Sept. 28, 1963], No. 39503/64. Heading B8A. A pivoted tube 5 for switching paths to alternative despatch tubes 3, 4 in a pneumatic despatch system is actuated by magnetic fields in such manner that it is initially withdrawn axially to break the sealed connection with the sealing surface 7 and is then moved sideways to the alternative position. Magnets or electromagnets 12, 13, 14 are arranged at the sealed connections and when the route is to be switched the polarities of the adjacent magnets as at 13, 14 are changed electrically to be in opposition so that the tube 5 is thrust axially against its spring-loaded pivoted joint 6. The polarities of one of the magnets (as at 12, 14) is also changed so that the tube 5 is then drawn towards the position opposite the tube 3. The tube 5 may carry a roller 19 engageable with a guide surface 18 having recesses 18a for the roller 19 at each station whereby the tube 5 is held away from contact with the sealing surface 7 while moving between stations. Spring-loaded end stops 16, are also provided.

Abstract: 1444347 Lubricating the inside of tyres DUNLOP Ltd 22 Aug 1973 [2 Sept 1972] 40824/72 Heading B2E [Also in Divisions B7 and C5] A gelled composition coated on at least a portion of the interior surface of a pneumatic tyre to lubricate regions which contact when the tyre is run deflated, comprises a liquid lubricant having a boiling point above 160C and preferably above 200C and a gelling agent therefor. Preferably the composition will not freeze at temperatures above -50C. The composition may remain as a coating to lubricate the run flat tyre, or may be broken down e.g. by shear, shear and temperature, a reagent, or a reagent in combination with shear and temperature (in the latter case the reagent will be included in the composition). The liquid lubricant includes a poly (oxyalkylene) glycol to which may be added one or more of alcohols e.g. ethyl alcohols, water, glycol ethers, soaps, alkalis, and polymers containing functional groups. The lubricant may be gelled by a finely divided gelling agent and the composition may be mechanically strengthened by the addition e.g. when the gelling agent is silica, of sodium stearate, sodium carbonate or hexamethylene diamine. The gelling agent may comprise silicates (e.g. clays, micas, asbestos) in the form of platelets, rods, fibres or spherical particles, silica, polar organic polymers (e.g. cellulose or nylon), crystalline polymers, or, when the lubricant includes a polymer containing functional groups, isocyanate, or metal oxides (e.g. magnesium oxide, zinc oxide or aluminium oxide). Reagents may include-for hydrogen-bonded gels-water, alcohols, acids, aprotic solvents (e.g. dimethyl formamide, dimethyl sulphoxide, tetra-hydrofuran) or certain aqueous inorganic salt solutions for ionic bonds-solvents of low dielectric constant; for gels using metal oxidesproton donors; for gels with weak chemical bonds (e.g. allophanates in polyurethane systems)-phenols. In examples disclosed a composition was prepared from poly (oxyalkylene) glycol-25g, silica-1.25g, with or without sodium carbonate- 0.25g. In a further example a composition was prepared from poly (oxyalkylene) glycol-25g, water-5g, alcohol-2.5g, silica-1.63g and sodium carbonate-0.33g. A suitable reagent for the above examples is hydrochloric acid in an amount 50% by volume of the volume of the gel. In another example poly (oxyalkylene) glycol-50g containing hydroxyl end groups was treated with a mixture of 2:4 and 2:6 tolylene diisocyanates (TD1) using cobalt naphthenate as catalyst, and the mixture was heated at 115C for 30 mins. TD1 in quantities of 3.3g, 2.2g and 1.6g gave, respectively, stiff, medium and soft gels. Other examples are disclosed which include poly (oxyalkylene) glycol, 5% (by weight) of silica, 11% (by weight) of water and sodium carbonate (in varying quantities), bicarbonate of soda, and borax. Also disclosed is a composition including poly (oxyalkylene) glycol and finely divided silica in an amount of 10g/100g of gel.
