Title: Apparatus for rerolling rolled sheet material
IPC: B65H35/00
Filed: 1975-05-01
Abstract: 1511263 Re-rolling rolled sheet material; winding webs CHROMALLOY AMERICAN CORP 1 May 1975 [10 May 1974] 18149/75 Headings B8M and B8R Sheet material 13a is unrolled from a supply roll 13 at a first station of an apparatus, advanced in a longitudinal direction and rerolled to form a roll 13d at a second station of the apparatus. The sheet is guided on to a support roller mechanism having three rollers 110, 111 and 112 by a guide roller 127 mounted on a pivoted arm 124. Shields 123 of the pivoted arm 124 assist in forming the initial roll 13d. The guide roller 127 is biased towards the roller mechanism so that it presses against one surface of the sheet, and as the roll 13d progressively becomes larger the arm 124, shields 123 and roller 127 progressively move away from the roller mechanism to assume the dashed line position (see Fig. 11) when the roller 127 presses against the other surface of the sheet material. Belts 12 trained around rollers 14, 15 translate the material towards the second station. The sheet material can be severed laterally by a rotating cutter blade 72 travelling along a lateral slot 71 relative to the longitudinal direction. The rollers 14, 15 are supported on a carriage 10 which is adjustable in lateral directions and is itself supported on an undercarriage 24. The carriage 10 pivots about an axis 42 when off-set rollers 45, 46, (47) and (48) Fig. 1 (not shown) are rotated by means of a handle 50 to control the unrolling direction of the material. Eject bars (55), operated by air-bags (57) Fig. 8 (not shown) can eject the supply roll 13 rearwardly when required. The material travels along a table 60 which has multiple ports 64 supplying pressurized gas or air for supporting the material. A pivoted arm 91 has a safety shield 90 to shield the blade 72 during a cutting operation and pivots, when actuated, to grip the material between its roller 103 and roller 104 to allow a meter (105) Fig. 1 (not shown) to register the material length. Actuator means 140 is used to rotate the arm 124 forwardly to dump the roll 13d. Air bags 152 and ejector arm 150 can eject the roll 13d. A control panel (175) Fig. 1 (not shown) controls the operation. The shields 123 may be made of polytetrafluoroethylene. The sheet materials include carpets, linoleum, paper, cardboard, rug cushioning materials, foam rubber, urethane foam, felt padding, textiles, canvas, roofing felt, burlap, plastics, leather, cork &c.

Title: Improved variable speed gearing for motor vehicles and machinery
IPC: F16D43/24
Filed: 1930-06-17
Abstract: 352,687. Variable -speed gearing. LAW, C., 3, Brentmead Place, Golders Green, London. June 17, 1930, No. 18486. [Class 80 (ii).] Variable-speed gearing comprises worm or spiral epicyclic gearing in which the speed is varied by adjusting resiliently the amount of friction in two similar toothed pairs. Upon a disc B fast on the driving shaft A is carried a spindle C with a worm G at one end and a spiral pinion E at the other. Worm G engages worm wheel J fast on driven shaft K. Pinion E engages spiral-toothed wheel M capable of a limited angular displacement relatively to shaft K. A spring R connects wheel M to a sleeve P having a helical connection with a sleeve S slidable on a straight spline on shaft K. The gear pairs GJ and EM are of the same ratio so that in the position shown in Fig. 1, the pinions G, E run idly round on the wheels J, M without driving. When sleeve S is slid towards wheel M, sleeve P is turned and spring R strained. Friction or grinding action is set up in the toothed gearing which causes shaft K to be driven. The speed is controlled by the position of sleeve S. A second spiral wheel N engaged by pinion E is loose and serves to equalize the action, like a flywheel. A second worm and pinion set is shown in Fig. 2 to increase and balance the drive.

Patent GB-403142-A (GB)
Title: Improvements in or relating to the production of compositions and goods containing two or more substantially mutually insoluble plastics
IPC: C08L91/00
Filed: 1932-06-30
Abstract: A plastic composition of two or more insoluble plastics dispersed one within the other so that the product contains three or more phases successively enveloping one another, all the phases except the last being in a dispersed condition, is produced by dispersing first one of the plastics in another as the continuous phase, then dispersing the mixture obtained in a third plastic, which may be identical with the first, and repeating the operations until the required number of phases is obtained.  For p  example, a continuous mass of one plastic is formed on mixing rolls or in an internal mixer, such as is commonly used in the rubber industry, and the second plastic is then dispersed into the plastic already on the rolls or in the mixer by gradual addition with continuous milling or mixing.  The dispersion so formed is removed from the rolls or mixing machine and is then in similar manner dispersed into a continuous mass of the third plastic by gradual addition and milling or mixing.  This sequence of operations may be extended to three or more successive dispersion operations.  Examples of three-phase compositions, commencing with the innermost are (a) casein, rubber, casein; (b) urea-formaldehyde, casein, urea-formaldehyde; (c) casein, urea-formaldehyde, casein; (d) urea-formaldehyde, phenol-formaldehyde, casein; (e) vulcanized rape oil (rubber substitute), casein, rubber.  In an example, a dispersion of 10 parts of dry casein in 20 parts of rubber is made, the latter also containing vulcanizing ingredients; into the warm mixing is incorporated a small quantity of ammonium hydroxide solution to soften the casein; a second quantity of 40 parts of casein with 15 parts of 10 per cent ammonium hydroxide solution is warmed to 100 DEG C. and is milled to a transparent mass into which the casein in rubber dispersion is milled so that the second casein mass forms the continuous phase; the composition can be subsequently moulded and hardened.  Other examples are given.  The invention does not include the preparation of multiple phase plastics in which rubber is dispersed in a plastic and the mixture dispersed in rubber, as described in Specification 403,141.

Abstract: 982,652. Solvent recovery from solutions of polymers. CRAWFORD & RUSSELL Inc May 25, 1961 [May 27, 1960], No. 18949/61. Heading B1B. An organic solvent, e.g. pentane, benzene, carbon tetrachloride, is evaporated from a solution of a polymer, e.g. ethylene-propylene copolymer, by injecting the solution into a liquid, having a temperature higher than the boiling-point of the solvent, in an apparatus wherein, after rapid evaporation of a substantial portion of the solvent, the "blown" polymer, in the form of one or more strands, floats on the surface of the liquid which is moving in a horizontal direction. Water, heated by steam pipes 14, Figs. 1 and 3, is circulated by pump 16 and conduits 15, 17 through tank 12 and trough 10. Polymer solution is pumped through slit 42, Fig. 6, or openings 24, Fig. 7, in manifold 25 beneath the surface of the hot water at one end of the trough. Evaporation of some of the solvent quickly takes place, and a ribbon 26 or several strands of polymer rise to the surface of the water. While the ribbon or strands are carried down the trough on the surface of the flowing water, the polymer is sprayed with hot water-from nozzles 28, whereby further evaporation of solvent takes place. The polymer and water spill over the open end 11 of the trough. The polymer is received on cotton-mesh, endless belt 36 which conveys it through the hot water in tank 12 in a completely immersed condition ; so that still more solvent is evaporated. The solvent vapours are conveyed by a hood 30 to a condenser. The polymer is withdrawn from the apparatus by conveyer 38. A salt solution may be used in place of water as the heat transfer and conveying agent. Methanol and ethanol may also be used.

A press comprises a fixed frame, a toolsupporting bed mounted for movement towards and away from a fixed tool, a doubleacting jack secured to the frame, and a plurality of connecting rods pivotally mounted on the frame, the ends of the connecting rods being connected to the jack and to spaced portions of the tool-supporting bed whereby reciprocation of the jack causes movement of the toolsupporting bed in a direction such that it remains parallel with its original position. A movable bending blade 1 of a press brake, having a fixed counter blade 2, is supported on a member 5 carried by side members 6 guided for vertical movement. The blade 1 is lowered and raised by a double-acting hydraulic jack 30, a piston 23 of which is connected by levers 16, pivoted at 17 to the fixed press frame, to the side members 6. The piston 23 is raised, to lower the blade 1, by oil delivered under pressure through a duct 34 to bear on that part of the face of the piston 23 surrounding a fixed stem member 28 and, through a duct 35 in the piston 23, on the end of an internal chamber 26 of the piston 23. The piston 23 is lowered, to raise the blade 1, by pressure oil through a duct 32, 31, 33, bearing on the lower annular surface of the chamber 26 surrounding the stem 28, the thrust on the piston 23 being thus much smaller than the previous upward thrust on the piston. The bending blade 1 may be replaced by a shear blade and a bending anvil 2 by a shear counter blade. Connecting rods disposed radially about the drive piston to distribute and balance forces applied over the surface of a platen may be used in a platen press.
