Patent GB-993192-A (GB)
Title: Electrolytic refining of silicon and germanium
IPC: C25C7/00
Filed: 1963-03-08
Abstract: Silicon or germanium is purified by passing D.C. between an anode in contact with a fused salt bath containing an oxide of the metal to be purified and a fluoride and a cathode in contact with another fused salt bath containing a fluoride, the baths being separated by a molten alloy of the metal being purified and a nobler metal, whereby the oxide is reduced to metal and deposited in the alloy and metal from the alloy is deposited in a purified state on the cathode.  The catholyte may be (1) an alkali metal cryolite or a mixture of such cryolites with or without an alkali metal or an alkaline earth metal fluoride or a mixture of such fluorides; (2) one or more alkali or alkaline earth metal fluorides; (3) one or more alkali or alkaline earth metal chlorides with one or more alkali or alkaline earth metal fluorides or fluosilicates; while the anolyte may be as in (1) and (2) above together with an oxide of the metal being refined.  For silicon refining at a bath temperature of 1000  DEG C. the catholyte also may contain silica and the molten alloy intermediate electrode is a copper-silicon alloy containing 16% silicon by weight.  For germanium refining at a bath temperature of 930  DEG C. the alloy used is a silver-germanium or copper-germanium alloy containing up to 50% germanium by weight.  The cell used is divided by a wall which dips into the molten alloy intermediate electrode and rotatably supports a stirrer which rotates in the alloy about an axis arranged vertically within the wall. Specification 989,452 is referred to.

Title: Improvements in or relating to apparatus for delivering measured quantities of liquid
IPC: B67D7/16
Filed: 1926-04-09
Abstract: 273,814. Shell-Mex, Ltd., and Lawson, J. April 9, 1926. Hose and flexible pipes. - In apparatus for delivering liquids by means of a flexible pipe, as in the case of a kerbside petrol pump with a horizontal swing arm designed to carry the petrol over a footpath, a small siphon tube is fitted in the delivery pipe in order to remove substantially all the liquid delivered by the measuring-chamber. Fig. 1 shows a delivery pipe 8 with a flexible pipe 10 terminating in a cock 12. Inside the pipes 8, 10 is a siphon pipe 14, the inner end of which is in a sump 13 and adjacent to a sight glass 15. In a modification, a small annular chamber 16, Fig. 2, is formed round the sump 13; in this liquid will remain when the siphonic action is completed.

Title: Aircraft engine propeller brake mechanism
IPC: B64D35/00
Filed: 1958-03-25
Abstract: 824,618. Helical band brakes. GENERAL MOTORS CORPORATION. March 25, 1958 [April 19, 1957], No. 9540/58. Class 103 (1). An aircraft propeller brake mechanism comprises a hollow brake actuator rod moved axially by a plunger through a helical spring to apply the brakes, a piston on the rod being subjected to pressure of the engine lubricating oil to act against the brake applying force and if sufficiently great preventing brake application. The brake mechanism comprises a helical band 39 surrounding a rotatable drum 17 mounted in the gear assembly on the output shaft of the engine, the end 43 of the band being anchored to a fixed member 45 and the other end being integral with a rotatable ring 46 having a peripheral tooth portion 47 engaging a tubular actuator rod 49 having an enlarged portion 61 slidable in a cylinder 62 and surrounding a plunger 55 bearing against the end of the rod 49 through a ring 81 and having a flange 57, a helical spring 59 being mounted between the flange 57 and the rod 49. The brake is applied by cam 76 engaging roller 79 on member 80 abutting plunger 55 and operating by compressed air supplied to the lower face of a piston 71 in cylinder 73, the plunger compressing spring 59 and moving the rod to rotate ring 46 to tighten the band. Air supplied from the source 67 to connections 84, 83 to the upper side of piston 71 moves cam 46 down to release spring 59 to move plunger 55 until stopped by ring 81, the band unwinding to move the rod 49 to the left. If the brake is applied when the engine is started a pump P is driven from the propeller to supply hydraulic fluid to chamber 63 between the rod portion 61 and cylinder 62 via filter F, check valve 91, chamber 93 and conduit 65 to move the rod to the left against the spring 59 to release the brake. During starting and shut down of the engine a plunger 97 moved by spring 99 prevents major flow of oil to lubricating passages 95, but allows a small bleed through passages 96, the plunger maintaining oil pressure in the chamber 93 to prevent application of the brake until the propeller speed has decreased to a safe value for braking, the brake then being applied by spring 59. Should the propeller then tend to rotate backwards the band 39 winds itself on to the drum to greatly increase its braking force. The brake may be applied manually by a pivoted lever acting on plunger 55, as in Fig. 5, not shown.

A method of image formation comprises dusting or grounded uncharged image support 11 with a mixture of several differently coloured photoconductive toner particles 13, each having a low photo-conductive response in the spectral region corresponding to its own colour and a higher response outside the spectral region. The particles are uniformly charged before or after dusting but prior to exposure so that the particles adhere to the support by induction.

Abstract: 581,322. Electromagnetic switches. IGRANIC ELECTRIC CO., Ltd., and GRAFTON, W. F. July 31, 1941, No. 9745. [Class 38 (v)] The accidental opening or closing of an electromagnetic switch by the shock of an explosion, gun fire &c. is prevented by inertia members 5, 6 which move when the shock occurs, so as to latch the switch in its closed or open position. The members 5, 6 are pivoted at 7 and pressed apart by a compression spring 10, separation of the members being limited by slots 8, 9 in them which receive a pin 4 on the armature 1 that is pivoted at 3. The pin 4 slides along the slots 8, 9 during opening and closing of the switch. Shock will move one of the members 5, 6 against the action of the spring 10 so that the pin 4 enters a pocket 11 in one of the slots and prevents, momentarily, the movement of the armature.

Title: Improvements in and relating to refractory bodies adapted for use as heat transfer media and/or as supports for catalytic materials
Inventor: REYNOLDS PETER WILLIAM
IPC: B01J21/16
Filed: 1950-04-21
Abstract: Substantially spherical, refractory bodies suitable for use as heat transfer media and/or as supports for catalytic materials are produced by incorporating a liquid adjuvant in a finely ground material comprising silica and alumina, the alumina content being from 72 to 42 per cent. by weight, mixing to a plastic mass, dividing, moulding the pieces into substantially spherical bodies between two surfaces between which there is relative motion, carefully heating to drive off and/or decompose the adjuvant, and then heating strongly, e.g. at 1450-1550 DEG C., to convert at least 70 per cent. of the alumina and silica content into mullite.  The starting material may consist of a mixture of alumina and silica, or, say, sillimanite, kyanite, andalusite or kaolin to which alumina may be added.  Up to 2 per cent. magnesia may also be incorporated. Suitable liquid adjuvants are water, mineral oil, diluted molasses, tragacanth mucilage, solutions of sugar or starch, greases, petroleum jellies.  In the production of the bodies, the plastic mass is rolled into rods between two moving parallel rubber bands, the rods being cut and simultaneously rolled between corrugated surfaces; alternatively, the rods are cut into short lengths which are moulded between two parallel rubber bands moving in opposite directions and at different speeds, the upper band also having a lateral reciprocating motion. The diameter of the bodies is suitably 3/4 in.- 1/16 in. Specifications 608,849, 628,321 and 630,549, [all in Group XIII], are referred to.  The Provisional Specification discloses (i) the granulation of a mixture of alumina, kaolin and water or molasses solution in a drum or paddle mixer, prior to drying and heating, (ii) pelleting, e.g. with punches and dies, to give bi-convex pellets of granules produced as at (i) above, but using graphite as a lubricant, and (iii) pelleting as at (ii) above, but using dies to give bodies having hemispherical ends joined by a short cylindrical section.
