Title: Improvements relating to aluminium phosphate and its production
IPC: C01B25/36
Filed: 1963-03-26
Abstract: Aluminium phosphate is recovered from a solid material containing it by treating under pressure with a saturated aqueous solution of SO2, or by passing SO2 gas into an aqueous slurry of the material, until at least a major portion of the aluminium phosphate dissolves; and recovering it from the separated solution. The material may be a naturally occurring mineral, e.g. the variscite-strengite series, and may first be ground to 5-40 U.S.S. mesh, and heated to 150-300 DEG C. to remove bound water. The SO2 treatment is preferably carried out, with stirring, at 20-40 DEG  C. and under a pressure of 0.14-3.5 kg/cm.2; sufficient water being added to retain aluminium phosphate in solution, and SO2 added to maintain saturation. The solution is then filtered, decanted, or centrifuged, and may be treated to give: (a) gel by sponging with hot air, steam, combustoin or flue gases, or by boiling at or below atmospheric pressure e.g. at 65-70 DEG  C., to remove SO2; the gel may be dried under vacuum at 65-95 DEG  C. and activated by calcination in air at 150-300 DEG  C., and has Al2O3:P2O5 ratio of 0.85-1.55, one volume of 0.35-0.75 cc/gm. and surface area of 110-235 m.2/gm.; or (b) crystals by heating at 150-225 DEG  C. under sufficient pressure to prevent evolution of H2O or SO2, cooling, and filtering; the crystals contain by weight 41-43% Al2O3, have Al2O3: P2O5 mol. ratio or about one, and a given X-ray pattern.

Title: Improvements in or relating to the colouring of oxide-coated aluminium and aluminium alloy articles
IPC: C23C22/83
Filed: 1947-05-05
Abstract: Oxide-coated aluminium or aluminium alloy articles are coloured by immersion in an aqueous solution containing ferric oxalate. The solution may also contain a soluble alkali metal or ammonium oxalate preferably in the proportion of 3 mols to each mol of ferric oxalate. Alternatively the ferric oxalate may be produced in solution by the addition of a soluble oxalate (e.g., potassium oxalate) to a solution of a ferric salt such as the nitrate, chloride or sulphate.  The amount of ferric oxalate used in solution may be 3-20 per cent, and preferably 5-10 per cent, and the pH may be 2-7 and preferably 6-6.5, pH adjustment being effected by the addition of, e.g., ammonium hydroxide to the solution.  The oxide coating is artificially produced, preferably anodically, and may be obtained by treatment of the aluminium or aluminium alloy with acids such as sulphuric or chromic, alkalis such as sodium carbonate or the alkali sulphate, and acid sulphates such as sodium or sodium acid sulphate; with or without the application of the electric current.

Title: Improvements in or relating to butterfly valves
IPC: F16K1/228
Filed: 1959-04-13
Abstract: 903,802. Valves. PARKER-HANNIFIN CORPORATION. April 13, 1959 [April 14, 1958], No. 12376/59. Class 135. The bore 11 of a valve housing 10, Fig. 1, has a reduced portion 12 with which co-operates a circular butterfly valve-closure mem ber 20 splined to an obliquely offset operating shaft 13 con nected, e.g. to an electric motor. A set-screw 22 enables the longitudinal position of the member 20 on the shaft to be adjusted; a seat 23 is disposed between the shaft and member 20- An annular peripheral groove on the lat ter houses a continuous flex ible metal sealing ring 30 Fig. 4, of G cross-section which is normally urged to the position shown by a sealing ring 35 of rubber or other resilient material; such an arrangement allows radial, transverse and pivotal movement of the ring 30 in the groove. The ring 30 is of larger external diameter than the internal diameter of the bore portion 12. The comparatively large relative movement between the ring 30 and member 30 which occurs during the last stages of valve closure results in a greater latitude in the setting of the means controlling the rotation of shaft 13. In a modification the rings 30, 35 are disposed in a groove in the housing 10.

Title: A device for filling and closing an aerosol container
IPC: B65B31/00
Filed: 1965-03-24
Abstract: 1,096,755. Filling and seating containers. COSTER TECNOLOGIE SPECIALI S.p.A. March 24, 1965 [March 25, 1964], No. 12432/65. Heading B8T. A filling and sealing head 1 which seals a valved closure member to an aerosol container and then supplies liquid propellant to the container via the valve, includes a collar 10 which engages the container top with - the closure member loosely in place, and is attached to a sleeve 7, whereby upward movement of the container relative the head causes the parts 10, 7 to telescope into the head against a spring 14, and claw members 30 are brought adjacent a container flange to which the closure member is to be secured. This upward movement causes an air valve 16 to be opened by a rod 15, whereupon pressure air enters a chamber 38 to force a piston 20 and shaft 23 downwardly against a spring 22; a wedge member 32 on the shaft is thus forced downwardly against inclined surfaces of the claw members to force them radially outwards to seal the closure member to the container. The valve stem of the container is received within packing 35 contained by a member 33 slidable within the wedge member 32 and urged downwardly by a spring 34 acting on a piston 29. After the closure member has been secured, the parts 29, 33 move upwards against the spring 34 and relative to the wedge member so that ports 43 become free of packing 45 and allow the passage of liquid propellant to the aerosol valve stem via passages 27, 28, 43 and 44. When a metered quantity of propellant has been supplied, a valve is operated to cut off the compressed air supply whereupon the various parts of the head return to their initial positions and the aerosol container is removed therefrom.

Title: Improvements in or relating to electric multi-channel pulse communication systems
Inventor: TREADWELL CYRIL GORDON
IPC: H04J3/06
Filed: 1950-05-18
Abstract: 669,227. Phase measurement. STANDARD TELEPHONES & CABLES, Ltd. May 18, 1950, No. 12450/50. Class 37. [Also in Groups XXXV and XL (c)] In a phase discriminator used in a pulse communication system (see Group XL (c)), having an automatic pulse timing system (see Group XXXV), the reference pulses 84, Fig. 3, F, are applied to terminal 85, Fig. 7, and thence to the paralleled suppressor grids of two gating valves 165, 166, the control grids of which are fed from terminals 90, 91 with gating pulses 174, 175, Fig. 3, E, respectively, from the taps of a delay network, Fig. 2 (not shown). The timing pulses 86, Fig. 3, D, are supplied to terminal 89 and thence, after inversion in transformer 169, to both control grids through diodes 171, 172, respectively. The valve 165 is thus unblocked during the interval between the leading edges of the pulses 84 and 86 to produce pulse 176, Fig. 3, G, at its anode, while valve 166 produces pulse 177 at its anode during the interval between the trailing edges of pulses 84 and 86. If the reference pulse 84 is symmetrically placed with respect to the timing pulse 86, pulses 176, 177 will be of equal duration. The balanced rectifier circuits 178 ... 186 produce zero potential at the output terminal 92 when pulses 176, 177 applied to their respective input circuits are of equal duration. Negative or positive control voltages are produced at terminal 92 depending on the direction and magnitude of the deviation of the reference pulse 84 from the symmetrical position relative to the timing pulse 86. This control voltage is applied to a master oscillator to vary its phase, to shift the reference pulse to the symmetrical position.

Title: Improvement in spindle and bearing therefor
IPC: F16C25/02
Filed: 1939-04-25
Abstract: 528,003. Bearings; lubricating. BRYANT CHUCKING GRINDER CO. April 25, 1939, No. 12455. Convention date, July 7, 1938. [Classes 12 (i) and 12 (iii)] A bearing bushing 4 has a circumferentially continuous inside face and is cut inwardly from its outward face to form a portion which can be displaced inwardly to take up wear. As shown for a grinding spindle, a pair of bushes 4 are mounted in a housing 6. Each bush has a pair of flexible integral portions 30, 31, formed by part circumferential slots 25 extending entirely through the wall thickness, and axial slots 28 extending partly through the wall thickness. The portions 30, 31 form the front and top parts of the bearing. The portion 30 may be flexed inwardly by a screw 40, and the portion 31 by a wedge piece 46 having a wedge face 47 engaging a ball 48 bearing against a wear plug 58. An end thrust ring 22 is secured to the shaft 1 and bears against a bushing 4 on one side and a collar 24 on the other. Each bush has two series of oil holes 70, 72 connected to passages 71, 73. The thrust ring 22 has radial oil grooves on each side the trailing edge of each groove being chamfered. Oil is led to the ring 22 by a passage 74 and escapes therefrom into passages 29, 76, to the supply dump. Means are provided for delivering lubricant at the openings 70. 72 at two different pressures. As shown in Fig. 6, a pump 81 supplies the passages 71, 73 through ducts 82, 84. The oil pressure is regulated by relief valves 85, 86, the valve 85 being set for a higher pressure than the other. The valve 86 may be rendered ineffective by closing a valve 88. The byepass from these valves leads to a duct 90 supplying the passage 74 at low pressure, and to an open ended pipe 91. The pipe 91 ensures that the thrust bearing runs in a bath of oil. The valve 88 is closed when starting the machine to enable oil at high pressure to be supplied, but after a short period of rotation it is opened. In modified arrangements the pipes 8, 84 have a choke coil inserted therein. Specification 528,443 is referred to.

Abstract: 429,402. Furnace atmospheres. BIRMINGHAM ELECTRIC FURNACES, Ltd., and LOBLEY, A. G., Tyburn Road, Erdington, Birmingham. April 27, 1934, No. 12695. [Class 51 (ii)] In the production of protective gases used in furnaces for the heat treatment of metals, hydrocarbons are burnt or reacted with sufficient air to convert the whole of the sulphur impurities in the fuel into SO2 and H2S, and the resulting products are then passed first through a cooler or condenser, in which sulphur is precipitated by reaction between the SO2 and H2S, and then through a purifier charged with materials such as lime, oxide of iron or sodium carbonate, which will absorb any remaining sulphur containing gas. The purified gas may be passed before use through a further cooler and a dryer, and through a chamber containing sawdust for the removal of carbon particles. The gas may be superheated either before or after desulphurization to crack the hydrocarbon content.
