Patent GB-109435-A (GB)
IPC: C22B19/00
Abstract: 109,435. Berglund, E. S. Sept. 5, 1916, [Convention date]. Furnace details.-Two or more electric zinc-reduction furnaces are connected to a common condenser in such a way that one or more of the furnaces may be shut off without disturbing the working of the remaining furnaces, and the formation of zinc powder is prevented or diminished. In the arrangement shown in Figs. 1 and 2 the furnaces 31, 32, having electrodes 3, 4, charging openings 5, 6, and slag openings 7, 8, are provided with outlets 9, 10, which conduct the zinc vapours along a common pipe 11 and inlet 12 into a chamber 13 provided with electrodes 14, vapour pipe 15 and condenser 16. Movable disks 21, 22 inserted in transverse slits in the pipe 11 serve to cut off either of the furnaces when desired. The chamber 13, in which the temperature of the zinc vapours may be regulated before they enter the condenser, may be dispensed with and the vapours conducted directly to the common condenser. By placing a layer of glowing carbon in chambers 13, the vapours flowing through may be purified.

Title: Method and material for making powder images electrically
IPC: G03G13/22
Filed: 1949-04-26
Abstract: 679,715. Producing photographs electrically. BATELLE MEMORIAL INSTITUTE. April 26, 1949 [May 1, 1948], No. 11014/49. Class 98 (ii). A method of making a powder image comprises producing an electrostatic charge image on an insulating image layer and flowing over the said layer a developer mixture of a powder which is attracted or repelled by electric charges and of a granular carrier, which powder and carrier are charged triboelectrically by contact with one another, said powder having a charge of opposite polarity and said carrier having a charge of the same polarity as that of the charge on the insulating image layer. The insulating image layer is either a photoconductive insulating layer (i.e. an insulating layer that is rendered conductive, when struck by light, at the parts so struck) on which an electrostatic charge image is produced by photographic exposure after uniform charging, or an insulating layer conforming in area to the desired image, the electrostatic charge image in this case being produced by charging the insulating layer. Typically a grounded metal plate covered with an insulating photo-conductive layer or with an image-wise layer formed by baking an exposed and developed bichromated colloid layer is charged by corona discharge while moving it past a series of points or parallel wires at a potential of 4.5-20 k.v., the insulating layer being charged to a potential of 100-1000 volts. The charge is retained only imagewise by the plate bearing the baked colloid layer but that bearing the photoconductive layer is uniformly charged and to produce an electrostatic image thereon it is exposed by projecting a light image on to it, thereby discharging the insulating layer imagewise, the potential falling to about 50 v. in the highlights. The plate is developed by flowing across it, as by tipping it, an electroscopic powder mixed with a granular carrier, the relatively massive carrier particles carrying the powder with them except when it is attracted by the charge concentration. The electroscopic powder may be ball milled particles of 0.1-20Á diameter of a heat-formed agglomeration of a phenol formaldehyde resin, a resinmodified phenol formaldehyde resin, asphalt, pitch or calcium lactate with a pigment such as carbon black, while the granular carrier which may be conducting or insulating particles of 30-60 mesh may be polymethyl methacrylate, sodium chloride, ammonium chloride, aluminium potassium chloride, Rochelle salt, sodium nitrate, aluminium nitrate, potassium chlorate, or zircon. The two materials may be mixed in a ratio of one part electroscopic powder to 15-100 parts carrier, the ratio of the components determining the contrast in the final image, any ratio being permissible provided that the carrier particles are sufficiently covered by the insulating electroscopic powder to be always of an insulating character. Specification 672,767 is referred to.

Title: Improvements in or relating to the removal of dust and sulphur compounds from flue gases by washing
IPC: B01D45/08
Filed: 1931-04-14
Abstract: 376,383. Washing gases. CORNER, G. H. C., McGINN, J., Norton Hall, The Green, Norton-on-Tees, and IMPERIAL CHEMICAL INDUSTRIES, Ltd., Millbank, London. April 14, 1931, No. 11075. [Class 55 (ii).] Flue gas is passed transversely through two or more successive sets of more or less interpenetrating curved vertical baffles down which water flows so that the gas moves sinuously from one concave surface to another without sharp change of direction, and dust and sulphur compounds are removed. Curvature of the transverse sets of baffles increases in the direction of gas flow, and the curvature of the final sets is reduced to avoid entrainment of water. The baffles may be so spaced that cleaner gas passes along the convex surface. The casing of the baffles is tapered toward the outlet, near which the sets of baffles are spaced more widely. Alkaline solutions, e.g. hot or cold lime water or milk of lime are sprayed on the baffles, which are of steel coated with vitreous enamel or with lead. Specification 358,103 is referred to.

Title: Improvements in or relating to the production of articles of or containing rubber
IPC: C08J5/02
Filed: 1932-04-19
Abstract: Threads, tubes, &c. are made by extruding aqueous dispersions of rubber and the like into a coagulating medium which operates partly or entirely under continuous penetrative osmotic action, and comprises a concentrated solution of a salt of a weak acid which is capable of considerable dissociation, together with such an amount of the weak acid that the Ph value is not lower than 5.0 and not higher than 6.5.  The aqueous dispersions are characterized by the presence of a substance adapted to react with the coagulating medium, and which until it has so reacted is substantially inert to the dispersions, but thereafter is decomposed into a mild coagulant effecting a smooth coagulating action throughout the thickness of the thread.  Suitable inactive substances which can be added to the dispersions are salts of a weak acid and a weak base such as the ammonium and ethanolamine soaps of the fatty acids and colophony. Specifications 219,635, 290,313, 303,544, 307,315 and 311,844, [all in Class 70, Indiarubber &c.], are referred to.

Abstract: 1,026,717. Clocks. P. S. B. INSTRUMENTS Ltd. March 22,1965 [March 20,1964 ],No 11898/64. Heading G3T. [Also in Division F2] The timing device is of the kind driven by a spring barrel and controlled by an escapement, and wherein a synchronous motor keeps the barrel nearly fully wound. The motor drives through wheel 15, Fig 2 (not shown) on barrel arbor 16 and relative movement between the barrel wheel and arbor operates a trip switch to stop the motor and prevent overwinding. A toothed wheel 21 eccentrically mounted on wheel 15 is engaged by a single slot 23 of a part 24 fast with the barrel wheel. Four revolutions, say, of the wheel 15, e.g. in twenty-four hours, serve to bring a pin 25 on wheel 21 into position to move a finger 40 of a spring- urged slide 37 so that a trip 30 moves inwardly to actuate a microswitch 29 and stop the motor. The subsequent movement of the barrel brings a pin 27 thereon into position to engage the end 41 of the trip and move it outwardly to again start the motor and allow the plate 37 to return. Alternate teeth of wheel 21 are cut away for half their length to facilitate operation, bearing an adjacent pair of full length teeth to act as stops limiting the angular movement of the wheel.
