Abstract: 420,824. Colour photography. BAKER, T. T., The Hut, Hatch End, Middlesex, and DUFAYCOLOR, Ltd., 19, New Bridge Street, London. June 6, 1933, No. 16300. [Class 98 (ii)] A multicolour screen for use in colour photography and kinematography is prepared by applying one colour to the surface of a film or base, printing a pattern of inky resist thereon from a printing surface, e.g. a roller, having mercurial ink-repelling areas, bleaching the colour from the parts unprotected by the resist, dyeing the bleached parts a second colour and removing the resists. The process may be repeated for producing a three-colour screen. In carrying out the process, a cellulose acetate film, prepared for example as described in Specifications 243,032, [Class 70], 281,803, 287,635,.or 301,439, [all in Class 2 (ii)], is coated with a layer of collodion, e.g. in a machine of the type described in Specification 321,222, [Class 140], dyed green with an alcoholic solution of malachite green and auramine. An irregular pattern in greasy ink is then printed thereon from a steel roller having inking areas 1 of chromium and inkrepelling areas 2 of mercury, and the dye is bleached from the unprotected parts with a mixture of alcohol, caustic potash, and acetone. The bleached parts are then dyed red with basic red N extra and the ink removed with benzene. A second ink resist falling indiscriminately on the red and green areas is then printed on the film, from which the colour is bleached in the unprotected parts as before, and the bleached parts dyed with an alcoholic solution of crystal violet and malachite green. The ink is removed with benzene and the film is dried, coated with a substratum e.g. of synthetic resin varnish and a layer of emulsion applied to it. The resist pattern may be irregular or regular and in the latter case the resist patterns are formed by sets of parallel lines and printed at right angles to one another. Specification 322,432, [Class 98 (ii)], also is referred to.

Title: Improvements in the production of staple fibres
IPC: D01G1/04
Filed: 1931-06-04
Abstract: 384,335. Severing fibres. BRITISH CELANESE, Ltd., 22, Hanover Square, London, and HALE, F. C., of British Celanese, Spondon, near Derby. June 4, 1931, No. 16404. [Class 31 (i).] Staple fibres are produced by cutting continuously fed filaments while gripping the filaments at points adjacent to the point of cutting and on both sides thereof, either continuously with their production in the case of artificial filaments, or otherwise. Suitable apparatus comprises a cutting blade, means for gripping the filaments on each side of the cutting point, and means for moving said blade across the path of the filaments. In the form shown, a pair of rollers, at least one of which preferably has a resilient surface so that the nip of the rollers covers an area, are provided and one or more cutting blades arranged to sever the filaments at the centre of the nip. The cutting blades conveniently rotate with the rollers and are actuated by a cam as each blade arrives opposite the nip. A slicing motion may be imparted to the blade, in addition to the radial cutting movement, either by separate cam means, or by so mounting the blades that a single operating means produces both motions. Slots are preferably arranged in one roller to be entered by a blade of the other roller, and the blades may be wide enough to cut a large number of filaments simultaneously. Means such as brushes may be provided to remove the cut fibres from the face of the rollers. The filaments 20 are passed over a feed roller 21 to the nip of the rollers 5. 6, each of which is provided with a rubber covering 9 and a plurality of cutting blades 11 actuated in turn as they arrive opposite the nip by the stationary cam 17 to sever the filaments whilst they are held on each side of the cutting blade. Brushes 23 remove any fibres which adhere to the rollers, the fibres being drawn by suction down a shoot 31.

Title: Improvements in or relating to method and apparatus for treating liquids containing suspended solids
IPC: C02F1/52
Filed: 1946-05-30
Abstract: 622,474. Gravity-separation apparatus INFILCO, Inc. May 30, 1946, No. 16446. Convention date, Oct. 26, 1942. [Class III] A process of clarifying liquids containing solids, such as sewage, by sedimentation in a tank, includes mixing the liquid to be clarified in a mixing zone with partially thickened sludge drawn from a level substantially spaced above the bottom of the tank whereby the solids suspended in the liquid are conditioned for sedimentation, and discharging the mixture into the tank at a level above the level of withdrawal of thickened sludge and below the liquid level. The mixing zone is preferably arranged within the sedimentation tank. A tank 1 is spanned by beams. 10, from which is suspended a cylinder 11, open at top and bottom, the lower edge being a suitable distance below the water level in the tank so that liquid escaping from under it will be clarified in passing to a launder 7. An inner cylinder 12, also open at top and bottom, is adjustably supported and carries an adjustably-mounted baffle plate 15, of diameter somewhat greater than that of the inner cylinder 12. The bottom of the cylinder 12 is substantially above the bottom ,of the tank 1, and its upper end is substantially below the liquid level but above the lower end of the cylinder 12. In use, the tank is filled with sewage, and a propeller 30 rotated to draw partially-thickened sludge in over the plate 15 into the inner cylinder 12, from which it passes into the cylinder 11 and then downwardly. Raw sewage entering through an inlet pipe 35 will become mixed with the rising column of partially thickened sludge, and its solid matter entrained therein. The mixture passing out from the lower end 21 of the outer cylinder 11, being of a density approaching that of the sludge at the level of the plate 15 tends to level off across the basin, and from this layer a quantity of clarified sewage corresponding to the rate of inflow, will rise to the launder 7. As a result of this levelling across the basin, the circulation effect of the propeller 30 extends to a layer over the whole tank area between the level of the lower edge 21 of the outer cylinder and the baffle plate 15. The space occupied by the mixing zone 11, 12 may thus be made quite small and the effective volume of the tank 1 not materally reduced. Also the circulation causes a substantial quantity of the liquid in the tank to be aerated by exposure to the atmosphere in the cylinder 11.
