Abstract: 1,195,795. Liquid filtering. HYDROMATION ENG. CO. 17 July, '1968, No. 33936/68. Heading B1D. A filter bed of granular plastics or wood saw dust, through which liquid normally flows from inlet pipes 84 to outlet pipes 87, is .periodically cleaned by fluidising the bed with additional clean or unfiltered liquid and forcing the resulting slurry to flow 'round a circuit including a wedgewire screen 81, through which liquid and filtered solids are withdrawn but which retains the filter medium. In Fig. 8, the screen 81 is in the filter tank 80, and pump ,103 delivers liquid to injection pump 97 to circulate the slurry. In Figs. 1 to 7, not shown, the screen (54) is located outside .the filter tank, and is of cylindrical shape and wedgwire construction, flow being inwards or outwards (Figs. 7, 5). Centrifugal pump (47) forces the .slurry round circuit (45, 46, 47, 50 55, 41) while pump (30), which normally delivers unfiltered liquid from tank (33), delivers filtered liquid from tank (37) to make up for liquid leaving the screen through outlet (58). This liquid is separated from the filtered solids by settling in tank (59). Outlet pipes (23), 87 are of helically wound wedgewire construction and closed at the tops, while inlet .pipes (16), 84 are perforated along one side (Fig. 4) and open at the top. At the beginning of a filtration cycle, the filter .tank (11), 80 fills with liquid and flow is downwards through the bed, later the flow is radial. The bed may be polyvinyl chloride .particles with pock marked surfaces, grown in an emulsion, spherical particles of foamed polystyrene, shredded polyethylene, polypropylene or .sawdust.

Title: Improvements in or relating to the manufacture of graphite
Inventor: REDDING GEOFFREY BRIAN
IPC: C01B31/00
Filed: 1965-08-09
Abstract: 1,147,456. Isotropic graphite. UNITED KINGDOM ATOMIC ENERGY AUTHORITY 8 Aug., 1966 [9 Aug., 1965], No. 34080/65. Heading C1A. Isotropic graphite is made by tumbling graphitic granules with smaller anisotropic grains and pressing the larger particles formed by snowballing into a coherent body. Suitable grains are made by graphitizing at 2,600‹ C. a calcined anisotropic petroleum coke crushed to below 50Á, mixing this graphitized material with a solution of phenol-formaldehyde resin and crushing and sieving the dried product to below 76Á. A stream of these prepared grains is sprayed with a solvent for the resin just prior to falling into a tumbling mass of granules, e.g. anisotropic graphite ground to 500Á. A charge of the "balls" formed is pressed at 2,000 p.s.i. whilst simultaneously being heated to polymerize the binder and, after removal from the pressing die, is baked in a gas stream to 850‹ C. and degassed under vacuum at 1,800‹ C. In a modification carbonaceous material such as calcined or non-calcined coke, is used for the grains, the granules, or both, and the balls formed are pressed into a coherent body which is then heated to graphitization.

Abstract: 859,647. Stuffing-box substitutes. GENERAL ELECTRIC CO. Ltd. July 28, 1959 [Oct. 24, 1958], No. 34099/58. Class 122 (5). In a shaft seal for a gas-filled machine, for example, a hydrogen-cooled alternator, in which a sealing liquid is caused to flow between cooperating sealing surfaces on a collar 2 fixed to the shaft 1 and a sealing member 7, the sealing surfaces extend axially and are arranged so that the flow of sealing liquid towards the inboard or machine-interior end of the seal is opposed by centrifugal action. Tapered sealing surfaces 3, 4 on the collar 2 co-operate with similar sealing surfaces 5, 6 on the member 7 which is slidable in a housing 8 but prevented from rotation by a pin 9 and sealing oil is supplied to the co-operating surfaces 3, 5 and 4, 6 from a chamber 12 fed through ducts 13 from an oilpressure chamber 14. Oil flowing to each side of the seal between the sealing surfaces is opposed by centrifugal action. The thrust on the member 7 is determined by the gas pressure in the machine and the oil pressure in chamber 14 and, if desired, the force in the inboard direction may be augmented by springs 18. The sealing surfaces on the inboard and outboard sides of the seal may be respectively radially and axially disposed.

[Class 18.] A powder box comprises a compartment 2, Fig. 2, for powder and a sieve 12 which supports a puff 10 ; and when air is driven into the compartment 2 by a pump or a rubber bulb 4, a cloud of powder is blown on to the puff. The powder is supported on an apertured plate 11 and the space 1 underneath constitutes an air compression chamber. The sides of the box may be vertical instead of inclined. In a modification, the sieve 12, Fig. 7, a cylinder 16, and the plate 11 constitute a piston arrangement pressed down against a spring or springs 15 by the lid 18. A leather cup washer 6 is held between the plate 11 and cylinder 16 so that, when the cover is removed and the piston forced upwards by the spring, air passes between the washer and the side of the box and enters the chamber 1.
