Patent GB-728183-A (GB)
Title: Aluminium photographic surfaces
Inventor: FREEDMAN MEYER LEWIS
IPC: C25D11/04
Filed: 1953-04-27
Abstract: 728,183. Aluminium photographic plates. HORIZONS, Inc. April 27, 1953, No. 11590/53. Class 98 (2). An aluminium base photographic plate capable of being stored without fogging is produced by oxidizing an aluminium plate in known fashion, followed by a second oxidation with an aqueous solution containing 0.01 to 10 per cent by weight of a salt or acid containing oxygen and a polyvalent metal in the acid radical, washing and drying the plate, impregnating the oxide surface with an aqueous solution of a silver salt, 0.1 to 2.0 per cent by weight of a hydrocolloid and a minor proportion of an oxidizing salt or acid as defined above, treating it with an aqueous solution of an alkali metal halide and a minor proportion of an oxidizing salt or acid as defined above, and washing and drying the thus treated plate. The second oxidation oxidizes any minute aluminium areas at the base of the oxide coating which are not oxidized in the first oxidation. Suitable reagents for this second oxidation and also for including in the water-soluble silver salt and the alkali metal halide solutions are chromic acid, or alkali metal ferricyanides, dichromates or chromates. Alternatively, the silver salt solution may be saturated with the silver salts of the above oxidizing agents such as silver ferricyanide or silver chromate. The silver salt is preferably silver nitrate. The hydrocolloid in the silver salt solution acts as a diffusion barrier to control the diffusion of the soluble salts and prevent the silver halide being formed in coarse crystals on the outer surface of the oxide layer. The hydrocolloid may be purified gelatin, polyvinyl alcohol, methyl cellulose or gum arabic. It is preferred to use an alkali metal chloride as the water-soluble halide, and after the formation of silver chloride, to immerse the plate in an alkali metal bromide and/or iodide solution, and such a solution may also contain a trace of silver nitrate. After the silver halide is deposited, the plate may again be treated with a solution of a mixture of alkali metal ferricyanide, bromide and dichromate. The first oxidation may be carried out by anodic oxidation in an electrolyte of oxalic acid and an oxalate of an alkali metal at a pH of 1 to 5, using either alternating or direct current, or by treating the aluminium plate with a solution of alkali metal dichromate, chromate or ferricyanide. The image formed by exposure and development in the usual way may be toned with gold or selenium. A final treatment to seal the surface consists in boiling the finished plate in a solution of sodium sulphate or acetate, or it may be treated with silicones or soap. U.S.A. Specification 2,115,339 is referred to.

Title: Improvements in and relating to machines for bending sheets or plates of metal
IPC: B21D5/02
Filed: 1948-04-30
Abstract: 640,605. Angular bending. RHODES, C. J. April 30, 1948, No. 11947. Addition to 556,836. [Class 83 (iv)] The mechanism employed in the parent Specification for cutting or shearing metal sheets or plates is applied to the operation of the beam 5 of a bending machine for bending sheets or plates of metal. The beam 5 is raised and lowered equally near each end by links 12 connected to levers 14 rocking about fixed pivots 15 and connected by links 17 to a common rod 20 which runs parallel to the beam and is slidable in either longitudinal direction in fixed guides by hydraulic means associated with pedal or hand-operated control mechanism. The beam 5 carries a bending tool 4 which is adjustable in relation thereto by worm gears on a shaft 8 driven by a motor 10. A fixed bending tool 3 is provided on the bed 2 of the machine and disposed beneath the tool 4. A double-acting piston 21 actuated by oilpressure in a cylinder 22 is attached to the end of the rod 20, which, when moved to the left as viewed in Figs. 1 and 4, acts through the links 12, 17 and levers 14 to feed the beam 5 in the downward direction. Oil is drawn from a reservoir 37 through filters 39 and supplied by a motor-driven rotary pump 36 to the cylinder 22 by depression of one of the foot pedals 24 or a hand lever 25. The pedals 24 and lever 25 are connected by a linkage to the control slide in a distributer valve 41 which is connected to the pump 36. As the beam is moving in the downward direction, oil flows from a port 44 in the valve 41 into a port 49 in the cylinder 22, while the oil in'front of the piston is forced therefrom back to the distributer valve 41 and reservoir 37. When the beam 5 has reached the end of the down stroke, a cam thereon contacts a trip lever to re-set the distributer valve 41 in the up-feed direction so as to reverse the direction of flow of the oil. The piston 21 moves to the right until the beam reaches the highest point in its travel, when the piston uncovers a port 48 and allows the oil to exhaust therethrough to. a return valve 55, into the valve 41 through the port 44 and out through a port 45 to the reservoir. The cylinder is provided with a draining valve 54 and a valve 53 to allow air bubbles to escape.

Title: Bag handle making and applying machine
IPC: B31B50/25
Filed: 1948-05-05
Abstract: 642,021. Bag handles. UNION BAG & PAPER CORPORATION. May 5,1948, No. 12316. Convention date, May 5, 1947. Drawings to Specification. [Class 133] Handles for shopping bags are formed from continuous strips of material, e.g. paper, supplied in rolls, the handles being made and affixed simultaneously in pairs. From the supply rolls the strips are drawn through a scoring device for scoring longitudinally and are thus divided into a central portion and lateral portions, which are preferably of slightly less width than the central portion. They then pass into contact with pasting means to apply paste to the lateral portions, through folders to fold the lateral portions inwardly on to the centre, one after the other. The strips pass between squeeze rollers for compression. The three-ply tapes are then passed through a drying compartment which has means for gradually converging them toward superposed upper and lower draw roll mechanisms, one for each tape. A pair of handle folding cylinders are arranged in the path of the bags, which are fed through the machine, and which cylinders are rotatable on horizontal axes and between which the bags pass. The said mechanisms pull the tapes to feed them transversely across the periphery of the respective handle folding cylinders on the sides diametrically opposite to the pathway of the bags. Each folding cylinder has a pair of spaced grippers which grasp the relevant tape when fed into position after guidance by suitable means, means being provided to sever the tape at the proper length to form handles. The grippers then firmly clamp the central portion of the strip which is the grip portion, against the periphery of the cylinder and carry the strip past folding cams which fold the ends backwardly at right angles to the central portion. Pressure rollers then engage the tape at the folds and permanently crease it. Further rotation of the cylinders carries the folded ends between guiding means to paster rolls whereby paste is applied to the trailing portions of the rearwardly folded ends. The pasted portions are applied to a bag as it passes between the cylinders, presser means on the cylinders firmly pressing the pasted portions into contact with the bag. As the bag passes on from the presser means, the grippers are retracted, and strippers detach the handles from the cylinders and guide the bags to a discharge mechanism. Suitable mechanism is described in considerable detail with respect to drawings.
