Title: Improvements in or relating to electric translating devices embodying thermal protective apparatus
IPC: H02K11/00
Filed: 1940-07-15
Abstract: 542,181. Protective cut-out arrangements. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. July 15, 1940, No. 11704. Convention date, July 13, 1939. [Class 38 (v)] A translating device, such as a motor having a running winding 34 and a starting winding 32 which is controlled by a centrifugal switch 33, is controlled by a thermostat 20 in the form of a bimetal disc mounted on the end bell 14 by means of a plate 26, and subject to a single-loop, bare-wire, radiant heater 24 and to a heat-storage coil 22 of insulated wire non-inductively wound into a compact mass and thermally insulated from the end bell by a disc 30 of felt-like material or "Micarta" (Registered Trade Mark). In Fig. 3 the coil 22 is in the starting-winding circuit so as to cause the thermostat 20 to quickly open the circuit 8 in the event of overloaded starting conditions or stalled rotor, the mass of the coil being such that the circuit is held open for a prolonged period of, say, three to five minutes. In modifications, however, it can be connected in the running-winding circuit, or in the main circuit so as to respond to starting and running conditions, Figs. 4, 5 (not shown). In a further form, Figs. 7, 8 (not shown), the coil 22 is inserted between two halves of the starting winding and carried on that winding, the thermostat being also located on the winding- side of plate 26. In Fig. 6 (not shown) a modified supporting arrangement is illustrated for the coil and thermostat, and the latter is included in the circuit itself so as to be directly heated. Where the coil 22 is in the running or main circuit, the continuous heating tends to accelerate tripping, but is counter-acted by raising the opening temperature of the thermostat or changing the resistance of heater 24.

Title: Improvements in or relating to the manufacture of low-friction bearing materials andbearing elements
Inventor: COLLINS JOHN HENRY
IPC: F16C11/06
Filed: 1960-04-06
Abstract: 929,886. Laminates. ENGINEERING PRODUCTIONS (CLEVEDON) Ltd. June 6, 1961 [April 6, 1960], No. 12200/60. Class 140. [Also in Group XXV] Low-friction bearing material is made by bonding a sheet formed from granules of a fluorocarbon resin, such as polytetrafluoroethylene, which is porous or apertured, to a backing of nylon or other synthetic-resinous or other material capable of penetrating the pores of apertures of the sheet, or to one or more layers of fabric impregnated with such material, and hardening. The sheet material may be rendered porous by mixing the granules of fluorocarbon resin, with or without a filler such as asbestos fibres or slate powder, with a soluble or volatile binder-which is leached out or otherwise removed after sheeting. Examples of binders are polymethyl methacrylate, which is afterwards volatilized by heating, and chalk subsequently dissolved out with dilute acid. Bonding may be effected by heat and pressure. If the sheet is apertured the holes 9, Fig. 9, may be coned or of dovetail shape to provide keys for the backing material 5. The sheet 8 may be shaped, for example to cup form as shown, before application of the backing, or the completed laminate may be shaped, e.g. into a bearing, bush or sleeve. Alternatively a porous fluorocarbon resin sheet or sheets 14, Fig. 7, may be applied to a ball joint member 11, or the similar shaped male member of a mould, and the backing material 13 injected into the joint socket 10 through an aperture in a closure member 15, or into the female member of the mould.
Patent GB-580987-A (GB)
Title: Improvement in and relating to the recovery and utilization of tin
IPC: C25C1/14
Filed: 1944-06-27
Abstract: Metallic tin is extracted from ores containing cassiterite (stannic oxide) or from sulphide ores, by the electrolysis, after purification, of a solution of alkali metal stannates or thiostannates formed by the fusion of the ore with caustic alkalies. After fusion, with preliminary roasting if necessary to remove sulphides, the ore is disintegrated and freed from excess alkali, which is subsequently re-used, by washing with water.  A second wash with water recovers most of the stannates in solution together with a large number of other metallic impurities which are precipitated, either hot or cold, by addition of hydrogen sulphide or solution of sodium or potassium sulphides, any soluble polysulphides being destroyed if necessary by the addition of a sulphite.  The tin is precipitated as stannic acid by treatment of the hot solution with carbon dioxide or sodium bicarbonate solution and washed to remove carbonates, whilst the residual carbonate solution is treated with lime to precipitate siliceous impurities and recover the caustic alkali for re-use in the fusion.  The stannic acid is then dissolved in caustic electrolyte from the cell to maintain the stannate concentration in the bath, iron anodes being used.  The Specification also refers to the use of mixtures of sodium and potassium salts, and to the use of potassium stannate and hydroxide in the cell and sodium hydroxide in the preliminary fusion.  In processes for use with tin-sulphide ores, the sulphide may either be fused with caustic alkali to produce thiostannate, the pure tin sulphide being precipitated by carbon dioxide and redissolved, or the sulphur may be removed as already stated, by roasting, and the material thereafter treated to produce stannic acid.  Chemical equations and figures of temperatures, efficiencies &c. are given in the Specification.
