Abstract: 766,827. Moistureproof regenerated cellulose film. BRITISH CELLOPHANE, Ltd. May 20, 1955 [May 26, 1954], No. 15601/54. Class 140. Regenerated cellulose film is treated with a polyalkylene imine before the application of a moistureproof coating comprising a vinylidene chloride copolymer. Preferred is polyethylene imine of viscosity 100 poises in 20 per cent aqueous solution at 20 C. The imine may be added to the viscose or cuprammonium cellulose from which the film is formed, or the film in the " gel state," before drying, may be passed through an aqueous bath containing say 0.01- 1 per cent imine at pH 4-11 and 15-80  C. In the latter case the film may be treated in a preceding bath with a softening agent, or a softening agent, e.g. glycerine or polyethylene glycol may be added to the aqueous bath. Alternatively, a thin coating of the imine may be applied to the finished dried film in solution, 0.01-1 per cent, in an organic solvent, e.g. ethyl alcohol, and the solvent evaporated by heat. The vinylidene chloride copolymer with e.g. acrylonitrile, methyl methacrylate, methyl acrylate, ethyl acrylate, with or without itaconic acid or anhydride, may be applied in aqueous dispersion or organic solvent solution to provide coatings 0.00005 inch thick on each side of the film.

The motor and pump portions of the pistons 90 may be of various cross-sectional areas to provide a number of different output pressures from the second pump unit. The first unit pistons 46 are supplied via a common inlet 65 and bearing 60, and deliver via passages 72 to corresponding second unit pistons 90, and via check valves 78 to a common outlet 84. The return strokes of pistons 90 are effected by a constant pressure obtained from the first pump unit output by a pressure-sensitive throttle valve 108 controlling a passage 110, spring 106 acting to close valve 108 when pumping ceases. Pistons 90 draw from a common inlet 132 via annular passage 128 and deliver to a common outlet 136. In the embodiment of Fig. 6 (not shown), inlet passage 128 is divided by lands 182, 184 and has separate inlets 131, 186 supplying groups of pistons 90, which deliver to separate outlets 135, 188, Fig. 5 (not shown). In the embodiment of Figs. 9 and 10 (not shown), the first pump unit comprises a vane pump with spring-loaded vanes 202 engaging a rotary eccentric 206. Liquid enters via a common inlet 218, annular passage 216 and inlet valves 212 and is delivered to second unit pistons 94 and to a common outlet 222 via outlet valves 214 and annular passage 220. In one application, the first pump unit pumps hydraulic fluid and the second pump unit pumps paint to a sprayer, the first unit being controlled by a by-pass valve either to actuate the second unit or to actuate a paint agitator. When applied to operating an hydraulic press, the first unit acts to bring the press to its work-engaging position, and the second unit then acts to supply high pressure for the pressing operation, the by-pass valve being controlled automatically. If the delivery lines of the second pump unit are closed, the second unit pistons stop reciprocating and the first pump unit delivers all of its output to the by-pass circuit.

Abstract: 104,161. Morrison, W. Feb. 14, 1916, [Convention date]. Variable-speed and reversing-gearing.-In transmission gearing for use on motor-vehicles &c., the load is driven through combined epicyclic two or more speed gearing and epicyclic reversing-gearing, which is itself preferably driven from the engine through a dynamo-electric clutch of the kind described in Specification 27617/13, [Class 35, Dynamo-electric generators &c.]. The driving- shaft 2 is driven from the engine E through a leather coupling G and a clutch F' of the kind referred to, and is supported in an oil-containing casing 1 with sediment chambers 6. The shaft 2 carries a boss 7 connected by a one-way clutch 8 to a drum 9, which carries a sun-wheel 15 gearing with a planet-wheel 41 integral with another wheel 42 gearing with a sun-wheel 43 on a sleeve 46. The wheels 41, 42 are carried by a drum 37 adapted to be connected by a Weston plate clutch 20, 34 with the drum 9 for the solid drive, the clutch being normally engaged by means of a spring 24 bearing against the armature 27 of an electro-magnet 68. One side of the armature carries the presser-plate 33 of the Weston clutch, and the other side carries teeth 28, Fig. 6, engaging teeth 65 on the stationary magnet 68 for the low speed. The armature 27 is connected to a ring 30, turning with the drum 37, by a one-way clutch 29. The driven sleeve 46 of the speed gear curries a pinion 47 gearing with planet-wheels 48 carried on a carrier 50 and gearing with an annulus 61 secured to a drum 60 on the load-driving sleeve 4, the gearing forming a reversing-gear.
