Abstract: 1314244 Steam separator GENERAL ELECTRIC CO 5 June 1970 [5 June 1969] 27378/70 Heading BIT [Also in Division F4] Fluid, e.g. steam, is made to flow through a processing device, e.g. dryer 28, in a direction different to the directions of flow into an inlet header 32 and out of an outlet header 33 by arranging the flow cross-section of the passages from the inlet header into the processing device to increase in the direction of flow into the inlet header, and the flow crosssection of the passages from the processing device into the outlet header to decrease in the direction of flow out of the outlet header. In the embodiment partly dried steam from a nuclear reactor generator (see Division F4) enters a drying arrangement comprising adjacent rows of dryers 28 having partitions 29 between the drier in a row and partitions 31 between the rows. Steam rises vertically into an inlet header 32 and is deflected to flow substantially horizontally through drier 28 by a flow control plate 34 which has holes increasing in number or in size towards the top. After removal of the water by contact with the corrugated vertical baffles the steam passes into outlet header 33 via a similar but inverted flow control plate 36. The fluid flow arrangement may be incorporated into a heat exchanger instead of a steam dryer and counter-flow of fluids may be used.

Damping apparatus for lithographic machines.-A lithographic printing plate is damped by applying liquid thereto in a continuous film in excess of that required, and directing a continuous air jet of blade form against the plate, whereby the liquid from the printing areas and the excess from the non-printing areas is displaced towards that side of the blade remote from the inking means, the blade being inclined at an angle between 0 and 33 degrees to the normal to the plate at the point of contact, in a direction such that the air forming the blade has a component of movement towards the inking means. As shown, the air blade is created by a slot 23 (of uniform dimension for a distance sufficient to minimize spread) which is formed by an adjustable top-plate 21 and a fixed wall 28 and is supplied from a source of adjustable high-pressure air, via a conduit 24. The air blade is raked back from the normal preferably 10 to 30 degrees (20 degrees as shown), the travel of the lithographic plate 11 on the plate cylinder 10 being upwards. Beneath the air blade, vacuum means is provided to remove the excess dampening liquid 20 from the plate 11; an adjustable plate 30 on a lower wall 29 forms with the wall 28 a chamber 33 connected at 34 to an extractor haying separating means so that the dampening liquid can be re-circulated. The dampening liquid may be applied by a roller close to, but not touching, the printing plate, as described in Specification 685,938; the applying roller may be driven so that its surface adjacent the printing plate travels in the same direction thereas at about <SP>3</SP>/ 5 ths of the linear speed, or in the opposite direction. Alternatively the dampening liquid may be applied by a wick dipping in a trough (Fig. 4, not shown) or by spray.

Title: Improvements in the production of fibrous sheet materials
IPC: D04H1/64
Filed: 1960-08-16
Abstract: 914,713. Coated bonded fibrous material; coated bonded non-woven sheet material. DU PONT DE NEMOURS & CO., E. I. Aug. 16, 1960 [Aug. 24, 1959], No. 28319/60. Class 140. A process for making moisture-permeable sheet material comprises forming a mat of staple fibres, impregnating the mat throughout with a solution of a synthetic polymer in an organic liquid solvent which is a non-solvent for the fibres, and precipitating the polymer and extracting substantially all the organic liquid solvent from the impregnated mat by treating it with an inert liquid which is miscible with the solvent and is a non-solvent for the fibres and for the synthetic polymers. Suitable fibres are polyethylene terephthalate, regenerated cellulose, cellulose acetate, polytetrafluoroethylene, nylon, copolymers of acrylonitrile and vinyl chloride, copolymers of vinyl chloride and vinylidene chloride, polyethylene and polystyrene. The mat may be formed by carding, by deposition on a foraminous carrier from a liquid suspension, or by air deposition. The mat may be needled before treatment with the binder. Suitable binders are polyurea polymers, plasticized polyvinyl chloride, copolymers of vinyl chloride with vinyl acetate or vinylidene chloride, copolymers of butadiene and acrylonitrile, copolymers of butadiene and styrene, and butyl rubber. Specified solvents are dimethyl formamide, dimethyl sulphoxide, tetrahydrofuran, tetramethyl urea, N,N-dimethyl acetamide and acetone. Suitable precipitants are water, glycol monoethyl ether, hydroxyethyl acetate and polyols, e.g. glycerol and ethylene glycol. Impregnation with the binder solution may be effected by immersion after which the mat may be drained or squeezed to remove excess liquid. Treatment with the precipitant may be effected by immersion or spraying. The mat may then be dried in an oven or by passage over smooth heated rotating drums. Examples describe the preparation of a binder polymer (i) from units of polytetramethylene ether glycol, tolylene-2,4-diisocyanate. The treated mat may be printed, stencilled, embossed or dyed, and may be coated on one or both sides, e.g. with polymer or copolymers of vinyl chloride, polyurethane elastomers, or synthetic rubbers, e.g. neoprene, copolymers of butadiene and styrene, or copolymers of butadiene and acrylonitrile.
