Patent GB-779098-A (GB)
Title: Resilient connectors
Inventor: JR ROBERT MOORHEAD CARRIER
IPC: B65G27/00
Filed: 1955-02-02
Abstract: 779,098. Jigging conveyers. CARRIER CONVEYER CORPORATION. Feb. 2, 1955, No. 3042/55. Class 78 (1). [Also in Group XXXII] The trough of a jigging conveyer is mounted on resilient mountings (see Group XXXII) which comprise blocks of rubber 224 (Fig. 47) in each of which is embedded a rigid strut. The latter is inclined at an angle to the vertical, and to the direction of movement of the trough which is divided longitudinally at 226, 226 into sections 221, 222, 223. The joint between adjacent sections is supported and sealed by longitudinal rubber strips 226a in each case. A modified form of connection between adjacent sections of the trough is shown in Fig. 29. The trough is vibrated by the action of a motordriven eccentric (not shown). In Fig. 34 a single unitary trough 173 is employed. The trough part is disposed between the resilient mountings 170, 171 in order to economize in height. A second conveyer of the construction shown in Fig. 34 may be mounted above a first conveyer of the same construction (Fig. 42, not shown) and may be driven by respective eccentrics on a common motor-driven shaft. In a further modification (Fig. 33, not shown) a single unitary resilient mounting extends the whole width of the base of the trough. A turnbuckle link may be connected between the trough and base of the conveyer adjacent each mounting, to ensure that the mounting will not be subjected to tension (Fig. 22, not shown).

Title: Palladium salts of condensed phosphoric acid
Inventor: CAMPBELL JOHN STEWART
IPC: C01B15/029
Filed: 1964-01-24
Abstract: Palladium metal is obtained from palladium salts of a condensed phosphoric acid by reduction with hydrogen in aqueous suspension.ALSO:Palladium salts of a condensed phosphoric acid having a polymerization number of from 2-14 are prepared by heating a halide, nitrate or sulphate of palladium and the condensed phosphoric acid or a precursor thereof, for example ammonium salts or hydrated monomeric acids such as orthophosphoric acid. The salts may be reduced to palladium suitable for use as a catalyst with hydrogen in aqueous suspension.  The salts may be used as catalyst in a process for producing hydrogen peroxide by contacting hydrogen and oxygen in the presence of liquid water. The salts may be in colloidal form or in comminuted form and the reaction is preferably carried out in acid medium. An oxygen-containing organic compound may be present, e.g. an alcohol, aldehyde, ketone, ether, ester, amide an oxygen-containing amine or carboxylic acid.  A hydrogen peroxide stabilizer as defined in Specification 1,056,121, may be present and the temperature and pressure conditions are described in Specification 1,041,045.  The hydrogen peroxide may be used directly for an oxidation process or the catalyst may be separated and the resulting solution evaporated.

Abstract: 1,194,174. Purification of sulphur. G. P. USTJUGOV, and J. S. CHERNOZUBOV. 21 Jan., 1969, No. 3296/69. Heading C1A. Sulphur is freed of bitumen and metalcontaining compounds, by boiling the sulphur, super heating the resultant vapours to above 1000‹ C., passing the super heated vapour through liquid sulphur at a temperature of 400-440‹ C., and recovering the sulphur from the so treated vapours. Suitably the sulphur is boiled in an evaporator, and the issuing vapours are passed up a vertical packed column, the bottom being heated to 1000-1100‹ C. and the upper zone is maintained at 400-440‹ C. forming by partial condensation a liquid layer of sulphur through which the sulphur vapours pass; the issuing gases containing sulphur, and H 2 S formed during decomposition of the bitumens, are then passed over a condenser at # 120‹ C. whereby purified sulphur is selectively condensed from the H 2 S.

Title: Improvements in the control of carburettors for internal combustion engines
IPC: F02D11/04
Filed: 1924-02-08
Abstract: 214,199. Barbarou, M. J. B. April 13, 1923, [Convention date]. Fluid-actuated valves. -The opening of the throttle valve of a carburettor for an aviation or motor vehicle engine is automatically modified or controlled according to the altitude at which the engine is working. The carburettor throttle valve 3 is mounted on a spindle 2, an arm 4 on which is connected to one arm of a bell-crank lever 6, Figs. 1, 3, keyed to a shaft 7. The other arm of lever 6 carries a stud 8 through the head of which can slide an arm 9 projecting from a ring 10 which can rotate about a piece 16 provided with an elongated hole 17 through which the shaft 7 passes. Another arm 11 on the ring 10 slides through the head of a stud 12 carried by a disc 13 moving freely over the shaft and actuated by the driver through a rod 15 and stud 14. The piece 16 is connected through a rod 19 to an elastic diaphragm 20 which divides a receptacle 21 into two chambers 22, 23 of which 23 is open to the atmosphere and 22 is connected with a vessel 24 in which any predetermined pressure may be produced. The diaphragm is also loaded by a spring 26. To open the throttle valve 3, the driver pulls the rod 15. This rotates the disc 13 which, through stud 12 and arms 11, 9, rotates the bell crank 6 and opens the throttle valve through rod 5. If the engine is at a low altitude the piece 16, ring 10 and the throttle valve are in the position shown in full lines in Fig. 1: At a higher altitude, the diaphragm will push the rod 19 so as to cause the piece 16 to slide over the shaft 7 and, the disc 13 and stud 14 being fixed, the ring 10 and arm 9 will be rotated to move the bell crank and open the throttle valve still further as shown in dotted lines. In a modification shown in Fig. 4, the throttle control lever 28 with pawl 31 works over a toothed quadrant pivoted at 29 and drawn by a spring 34 against a stop 33. The quadrant may however be moved to modify the throttle position by a diaphragm 35 similar to the diaphragm 20, Fig. 1, which acts on the quadrant through a rod 35<a>, pin 38, and slot 39.

Abstract: 1,153,015. Electrolytic machining. PHILIP MORRIS Inc. Jan.25, 1967 [Feb. 10, 1966], No.3798/67. Heading C7B. A method of electrolytically shaping a surface on a continuous conductive workpiece comprises passing said workpiece past anode and cathode in spaced relation therewith, the cathode having a working surface adapted to generate the desired predetermined shape on the surface of the workpiece, the gaps between workpiece and the anode and cathode respectively being filled by electrolyte so that the workpiece forms a bi-polar electrode, and electro-machining thereof may take place without physical contact between electrodes and workpiece. The invention is particularly applicable to the sharpening of continuous strip razor-blade blanks. Using the apparatus shown a razor-blade strip 11 is passed through a slit 18 formed in a fixture 10, to which electrolyte is supplied via inlets 20, 21 and feed channels 22, 23, which fixture is provided with anodes 25, 26 extending into said slit 18 so that one edge extends longitudinally therealong (see portion 27) parallel to the razor-blade strip, cathodes 30, 31 extending into the slot throughout its length and having working surfaces 32 positioned parallel to the blade edge to be sharpened and at a distance of less than 0À010 therefrom, and an electrolyte outlet 38, constructed such that the electrolyte pressure, which may be up to 350 lb/ square inch within the slit 18, drops considerably after passing between the cathodes 30, 31. In this form part of the current flows direct from anode to cathode without passing through the workpiece. Embodiments are also shown in which the chambers forming the slot through which the workpiece passes and into which anodes and cathodes are passed are maintained separate from one another, to thus prevent contamination of the catholyte by chlorine formed at the anode Fig. 4 (not shown); in which the strip is passed through the apparatus horizontally, two sets of electrodes being positioned therein such that both edges of the blades are sharpened therein, Fig. 6 (not shown) the workpiece being passed therethrough by means of a sprocket wheel which engages the slots formed in the razor blades Fig. 5 (not shown); and in which the cathodes may be adjusted laterally of the blade strip by a worm gear arrangement. An electrical circuit is described Fig. 1a (not shown) in which current from a 3-phase A.C. source is fed to the electrolytic cell via silicon controlled rectifiers connected respectively with bi-pass diodes to allow variation of the current, a transformer bank, diodes for rectifying the current, a filter capacitor for smoothing the resultant D.C. current. The cell may be operated using either constant current or constant voltage.
