Inventor: COPLEY DONALD WILLIAM
IPC: B60H1/12
Filed: 1962-08-07
Abstract: 1,031,729. Ventilating vehicles. SMITHS INDUSTRIES Ltd. Aug. 6, 1963 [Aug. 7, 1962], No. 30271/62. Headings F4U and F4V. In a system for both cooling the engine and warming the interior of a vehicle, air is directed over a radiation 10 by an engine-driven impeller 14 and through a pipe 19 to the vehicle interior, a valve 21 responsive to engine coolant temperature controlling the air flow through the radiator to keep air temperature in pipe 19 substantially constant, and an automatic pressure-release valve 25 being associated with pipe 19. Cool air supplied from atmosphere by impeller 33 is mixed in chamber 20 with the warm air, valve 37 adjusting the proportions. The position of valve 37 is set by manual operation of rod 44. When valve 37 is closed on pipe 31 or in an intermediate position, valve 25 is maintained against stop 56 by spring 26. When valve 37 is closed on pipe 19, the lost-motion between pin 51 and slot 50 is taken up and bell-crank lever 52, 54 rotated clockwise against the action of spring 57, and rod 30 causes lever 28 to pivot at 29 and open valve 25 further. After manual setting, valve 37 is adjusted to maintain a constant air temperature to the vehicle interior. This is done by capsule 43 of volatile liquid controlling the movement of element 40 and thus the pivoting of lever 38 about pivot 49.

Title: Electric signalling system
IPC: H03C1/52
Filed: 1924-12-17
Abstract: 241,417. Huizinga, M. J. Dec. 17, 1924. Modulating systems and apparatus; combined transmitting and receiving arrangerrients; coupling oscillating and radiating circuits. - A highfrequency signalling system in which no carrier wave is radiated during the intervals between the signals, comprises a local or storage oscillating circuit and an output or radiating circuit connected to two nodal points in the local circuit, or to two points at which the voltage is always the same in magnitude and phase. Energy is radiated only when the frequency of the oscillations or the electric constants of the local circuit, or both, are modulated. As shown in Fig. 3, the local circuit comprises two inductances and two condensers C<1>, C<2>. Oscillations are produced by a high-frequency generator and a coupling coil. The aerial and earth are connected respectively to points B, A in the inductances at which normally there is no voltage difference. Two microphones M<1>, M<2> connected together to form a push-pull arrangement, such as two carbon containers on opposite sides of a single diaphragm, are shunted respectively across the two halves of the lower coil, for causing modulation. In the system shown in Fig. 4, the oscillations are caused by a thermionic valve. Modulation is effected by the two condensers C<1>, C<2> which are combined to form a push-pull condenser microphone comprising, for instance, an oscillating diaphragm interposed between two rigid plates. In the modification shown in Fig. 6, the local circuit comprises a single inductance and condenser C. Oscillations of a frequency double the natural frequency of the circuit are caused by a high frequency generator and induction coil and tho output circuit is connected to two nodal points A, B in the inductance. Modulation is effected by suitable devices not shown. A receiver may be connected to the same aerial, a current limiting device being interposed to prevent the receiver from absorbing too much energy in the period of transmitting.

Patent GB-1013007-A (GB)
Title: A process for the preparation of polymer solutions from polymer latices
IPC: C08J3/09
Filed: 1964-08-04
Abstract: A solution of natural rubber or a homo- and/or copolymer is prepared by mixing the latex with at least one solvent in which the polymer is soluble, removing the latex water from the mixture by distillation during or after the step of mixing with solvent and freeing the mixture then remaining from impurities originating from the latex. Polymers exemplified are natural rubber and copolymers of butadiene/styrene and vinyl chloride(vinyl acetate. Solvents used are isooctane and white spirit.  The polymer-solvent mixtures are purified by successive extraction with water, aqueous methanol solutions which may be rendered alkaline, and water.  Other suitable extractants include saturated aliphatic alcohols or ketones with 1 to 4 carbon atoms, which same liquids may also be included initially in the solvent-latex mixtures. Further purification of the resultant polymer solutions is effected with conventional adsorbants.  The resultant polymer solutions may be hydrogenated using Ziegler-type catalysts or may be oxidized by blowing air or oxygen through the solutions.  The solutions may be used as adhesives or as lacquers and/or varnishes, especially as tin lacquers.
Patent GB-397708-A (GB)
Title: Improvements in and relating to an electrically controlled toy vehicles
IPC: A63H30/00
Filed: 1932-10-31
Abstract: 397,708. Distant-control systems. DOMBRINE, M. A., 49, Avenue Aristide Briand, Montrouge, Seine, France. Oct. 31, 1932, No. 30660. Convention date, Nov. 16, 1931. [Class 40 (i).] In an electrically-controlled toy vehicle wherein all the operations are controlled from a single fixed apparatus, the vehicle is connected to the control apparatus by a flexible cable that allows the operator to drive and steer the vehicle in any direction without the vehicle being compelled to follow any fixed path. Steering of the vehicle is effected from the control station, Fig. 6, by rotating a spindle 59 carrying a toothed wheel 63 situated below an insulating disc 62. Clockwise rotation of the spindle, through a spring arm 67, Fig. 9, frictionally mounted thereon, rocks a plate 64 to cause a contact 66 to brush against the ends of the teeth of the wheel 63. A series of impulses are thus transmitted to a magnet 441, Fig 4, on the vehicle, that repeatedly attracts a lever-arm 39<1> and through a stud 35 rotates a ratchet wheel 33 connected to the track bar of the vehicle. Similarly, counterclockwise rotation of the spindle 59 through a contact 65 energizes a magnet 44<2> to move the track bar in the opposite direction. In a modification, Figs. 10 and 15, the vehicle is steered by rotating a spindle 142 whereby an insulated cam 144 frictionally mounted on the spindle is positioned to allow one of two spring contacts 141<1>, 141<2> to brush against the teeth of a wheel 140 rigid with the spindle. Impulses are thus transmitted to one of two magnets 117<1>, 117<2> that repeatedly attracts a roller 116 and thereby causes a shaft 115 geared to the track rod 112 to rotate.

Title: Improvements in or relating to lubricating arrangements
Inventor: HAWORTH LIONEL
IPC: F01D25/18
Filed: 1955-10-26
Abstract: 806,922. Lubricating. ROLLS-ROYCE, Ltd. Sept. 11, 1956 [Oct. 26, 1955], No. 30685/55. Class 12 (3). [Also in Group XXVI] In a lubricating system for the bearings 104, 105 of a layshaft 101 of a reduction gear of a gas-turbine engine, chambers 124, 135 located within the shaft 101 are adapted to trap lubricant when the shaft ceases to rotate and means are provided for delivering the trapped lubricant from the chambers to the bearings when the shaft again starts to rotate. Located within the shaft 101 are sleeves 106, 111 forming chambers 117, 124 which are separated by flanges 114, 118 having holes 122, 116 providing passageways for oil. The space between the flanges 114, 118 is divided by a pair of radial walls 119 and the spaces so formed communicate with the space between the sleeve 106 and shaft 101 through drillings 121. A similar arrangement is provided at the other end of the sleeve 111 where a chamber 135 is formed. Oil enters the chamber 117 through a fixed nozzle 109 and due to centrifugal action the oil tends to form an annulus in the chamber 117. Some of the oil passes through holes 116 into chamber 124 from which some oil reaches the bearing 104 via ports 122, 121, and some oil reaches bearing 105 through ports 141, 140. When the shaft 101 stops rotating, oil is trapped in the chambers 124, 135 which is subsequently fed to the bearings 104, 105 when the shaft starts to rotate again. A similar arrangement is employed for feeding lubricant to the faces of the turbine discs, for prevention of corrosion, when the engine begins to rotate (see Group XXVI).

Title: Treatment of ores or other materials for extracting lead sulphate therefrom
IPC: C22B3/08
Filed: 1926-12-08
Abstract: 287,207. Dietzsch, F. Dec. 8, 1926. Copper and lead sulphites, sulphides, sulphates, thiosulphates, carbonates, oxides; calcium thiosulphate; silver sulphide and thiosulphate.-Oxidized oxide or roasted ores are treated with a solution of thiosulphate simultaneous with, or after, treatment with a solution of sulphur dioxide, to extract copper or lead and zinc or silver. Solutious of cuprous sulphite and lead sulphite or sulphate are formed. If the lead is present almost wholly as sulphate the sulphur dioxide is omitted. The metals are precipitated by adding a sulphide, polysulphide, carbonate, hydroxide or oxide of an alkali or an alkaline earth metal and the alkali or alkaline earth thiosulphate formed is used in further treatment. The alkalithiosulphate solution may be used concentrated under pressure or at a raised temperature. Sulphuretted hydrogen may be used to precipitate the metals, and the decomposed thiosulphate mav be regenerated by heating with lime and sulphurous acid and preferably sodium sulphate: e.g. an oxidized copper ore is leached with a sodium and calcium. thiosulphate solution saturated with sulphur dioxide and with an excess of the calcium salt present to prevent formation of s dium sulphate. The solution is recharged with sulphur dioxide reused, and finally freed from the gas by passing through fresh ore. The copper is precipitated by lime or sodium sulphide. A roasted argentiferous lead zinc ore is leached several times by a sulphur dioxide solution recharged after each leaching, and is then washed with water to clean it from zinc solution. The lead and silver are next separated by similarly washing with a solution of sodium and calcium thiosulphate and sulphur dioxide, the solution being finally freed as above from sulphur dioxide. The lead is precipitated by lime and the silver by sodium thiosulphite and sulphide. The zinc solution is boiled, forming first zinc monosulphite then sulphite and sulphate, and iron hydroxide. Zinc thiosulphate is formed by adding sodium and calcium thiosulphate solution. Ferric hydroxide is precipitated on boiling and passing in compressed air, or the iron is precipitated by chalk. Zinc hydroxide is precipitated by lime.
