Patent GB-849103-A (GB)
Title: Improvements in or relating to manifolding
Inventor: FRANCIS FREDERICK GEORGE
IPC: B41M5/124
Filed: 1955-11-24
Abstract: 849,103. Colour-reactive copying paper. CARIBONUM Ltd. Nov. 6, 1956 [Nov. 24, 1955], No. 33763/55. Drawings to Specification. Class 96. [Also in Group XV] Manifolding paper carries a substantially colourless transferable non-acid coating including leucauramine as a reactant which is capable of producing colour when brought into combination with a second reactant included in a substantially colourless non-transferable coating carried by a sheet of copy-receiving paper. The leucauramine is preferably carried in a slightly alkaline oil and/or wax vehicle, e.g. methylcyclohexanol phthalate, spindle oil and/ or petroleum jelly, or a wax or wax-like substance, e.g. paraffin wax, carnauba wax, hydrogenated castor oil or beeswax. The second reactant is preferably tannic acid and/or phosphotungstic or phosphomolybdic acid or an alkali metal phosphotungstate or phosphomolybdate. The tannic acid is preferably dissolved, e.g. in dibutyl tartrate, and the solution may be applied as an aqueous emulsion. The leucauramine may be coated on one or both sides of paper sheets. If on one side, the paper may be coloured, and the coating may be made white by inclusion of titanium dioxide or zinc white. If coated on one side of white paper, the other side may be distinguished by printed markings. The second coating may be applied to the other side of paper coated on one side with the leucauramine, or may be applied to separate sheets of paper which may be semi-transparent to permit markings developed on it to be read positively through the paper. Paper carrying a leucauramine coating may be pre-coated with a thin layer of gelatine, methyl cellulose, ethyl cellulose, cellulose acetate, polyvinyl alcohol, dextrin, shellac or gum arabic. An example of a transferable coating contains hydrogenated castor oil, petroleum jelly, ethyl ether of Michler's hydrol, and leucauramine. Examples of receptive reacting coatings are (a) tannic acid, dibutyl tartrate, dextrin, blanc fixe, phosphotungstic acid and water. Examples of barrier coatings are (a) "Cellofar B " (Registered Trade Mark), water, and sodium carbonate; (b) ethyl cellulose, tricresyl phosphate, toluene, butyl alcohol, methylated spirit and caustic soda; and (c) gelatine, glycerine, water and sodium carbonate. Specifications 712,216 and 757,136 are referred to.

Title: Actuating mechanism for hoisting machine
IPC: B66D1/22
Filed: 1962-09-06
Abstract: 1,011,155. Hoist control systems. S. T. BUCK. Sept. 6, 1962, No. 34240/62. Headings B8B and B8H. [Also in Division F2] In a guided platform hoist, Fig. 1 (not shown), a vertical control cable 22 adjacent the path of movement of the platform is fitted with a plurality of steps 25 and the platform carries a projection 26 which can engage any of the steps and thereby pull on the cable to cause it to actuate hoist drive stepping means. Successive steps 25 are of progressively larger sizes and the platform extension 26 has an aperture 29 through which the cable is threaded and an adjustable cover-plate 30 for this aperture. The cover-plate 30 has apertures 31a to 31d, Fig. 3, whose sizes correspond to these of the steps 25 so that the device can be set to engage only one of the steps during an upward trip of the platform. The cable 22 is secured to the periphery of a wheel 20, Fig. 4, rotation of which turns a cam-shaft 19 whose cams 76, 77, 78 operate a brake 16 on a winch drum 14 by which the hoist is operated and a clutch 15 which couples an I.C. or other motor 11 to the winch shaft 13. The clutch cams 76, 77 respectively control operation of two clutch elements one of which causes the winch to wind the platform up and the other to lower it. The shaft 19 is free to rotate through a small angle on each side of a neutral position in which the brake is on and both clutches disengaged and the two end positions of this rotation produce conditions in which the brake is off and one clutch element is engaged. The winch is started by manually turning the wheel 20 or a handle 37 to rotate shaft 19 into its appropriate end position, in which position a detent cam 21 holds it until the stop-operated cable pull returns it to the neutral position. The clutch, Fig. 7 (not shown), comprises an epicyclic gear whose planet pinions are meshed with a wheel which can be arrested by a brake band operated by cam 76 and are mounted in a housing which can be arrested in like manner by operation of cam 77, the arrangement being such that the driven shaft 13 rotates in opposite directions in accordance with which clutch member is arrested. Specification 1,010,297 is referred to.

Abstract: 846,551. Packages; wrapping-machines. ROSE BROS. (GAINSBOROUGH) Ltd. Nov. 6, 1957 [Nov. 9, 1956], No. 34245/56. Class 94(1). Packages comprising two separate compartments filled with different liquids, e.g. the constituents of a shampoo, are formed by feeding three opposed portions of heat-sealable material, sealing longitudinal marginal portions of the material by heat and pressure to form a continuous tube with a central dividing wall, sealing the tube transversely at intervals by heat pressure and, after each transverse sealing operation, introducing separate quantities of liquid into the tube on opposite sides of the dividing wall. As shown, a pair of opposed outer webs 11 and an inner web 12 pass over guide rollers 13 and are fed downwardly by pairs of intermittently-driven rollers 14 arranged to engage the marginal portions of the webs, the latter passing between laterallyspaced pairs of heated, longitudinal sealing members 16 which are reciprocated in synchronism with the operation of the rollers 14 to form the webs into a tube sealed along its longitudinal edges. Liquid-supply pipes 17, each connected to a piston-type pump, pass one on each side of the inner web 12 and extend into the sealed tube. Arranged below the rollers 14 is a pair of heated lateral sealing members 10 which are reciprocated in synchronism with the members 16 to form lateral seals at intervals to complete a series of packages 19, of the form shown in Fig, 2, which are subsequently separated by knives 21 and fall on to a delivery conveyer 22. The members 16 and 18 are attached to common frames 23 reciprocated by rods 24 connected by crossheads 27 attached to cam-operated links 28. According to the Provisional Specification, the transverse sealing operations may be effected below the level of liquids in the tube.

The lathe or like machine tool may be provided with a tool slide 3, Fig. 3, adjustably connected to an hydraulic copying piston 18 of known type controlled by a stylus 12. The latter is adapted to contact selectively one of a number of templates such as 30a projected from a casing 35 supported from the lathe bed by brackets 10. The different templates are held in grooves in the forward edges of template-carrying plates 36, 36a, 36b, Fig. 4, which are arranged in parallel relation, one above the other in guideways within the casing 35. The back parts of the carriers are cut away and each back edge is connected to the piston 40, 40a, or 40b, Fig. 2, of a pressure cylinder 38, 38a 38b, respectively so that a selected template may be projected to bring it into position for contact with the stylus 12. The templates are arranged for limited float in the horizontal plane and may be accurately positioned by gauge screws 52, 53. Spring flap-members close the front of the casing 35.
