Title: Method of and apparatus for filling containers such as cans
IPC: B65B31/04
Filed: 1930-09-02
Abstract: 364,646. Bottling ether. DEHN, F. B., 103, Kingsway, London.-(Mallinckrodt Chemical Works; 3600, North 2nd Street, St. Louis, Missouri, U.S.A.) Sept. 2, 1930, No. 26193. [Class 125 (ii).] Relates to filling cans with ether &c. by methods in which the cans are filled with inert gas which is subsequently displaced by the incoming liquid. According to the invention the air is removed from the cans &c. by counterflow-diffusion with nitrogen &c. as the liquid is introduced. The apparatus employed comprises a base 1 arranged at a slope of 4‹ so that the liquid in the supply tank 24 will be deeper on one side (see line A-A), Fig. 1. Cans are supplied to a rotary can-wheel 23 by a conveyer 101. The wheel 23 revolves intermittently at thirty-two movements per revolution, and has thirty-two can-receiving recesses on the periphery each provided with a can controller 85. Supported on a base E is a fixed wheel 9 having a can raising cam 11 at its outer periphery and a cam and valve plate on the inner hub thereof. The wheel 23 is rotated by a hub on the vertical shaft 15 which carries the tank 24. Telescopic nitrogen tubes 35 co-operate with ether tubes 37 and are operated by a cam 27. The intermittent rotation of the wheel 23 is controlled by a ratchet and pawl mechanism 41 and is imparted thereto by a pawl 43 operated through linkage 65, 61, 63, 47 from the shaft 69. As each can is pressed into a recess 85 it engages a control pin 107 which co-operates with an actuating rod 127. The rods 121 extend into the tank 24 where they control ether valves which deliver measured quantities from cups through the pipes 37 to the cans D. If there is no can in a recess 85 the ether valve corresponding to that recess is not operated. The cans are lifted by elevators 139 operated by the cam 11, into contact with the sealing heads 147. Caps Fare fed by a supply pipe 5 to a passage 163 from which air is excluded by a gate valve 165 when the valve is down. The nitrogen tubes 35 surround the ether tubes and have openings 177 communicating with a slot 181, and thence to the valve ports 183. Openings 187 are provided in the tubes for ejecting nitrogen. The valves 195 are operated by feelers 209 which are engaged by the cans as they are lifted, and ether and nitrogen are supplied simultaneously to the cans therefrom. The displaced air passes out by a port 197. The capping head 291 comprises two die-blocks which are closed around the capsule by downwardly moving spurs. A rail 105 holds the cans in the wheel 23, and diffusion of air and nitrogen takes place over twelve movements of the wheel before the ether valve is opened. Ether and nitrogen flow into the cans during the fourteenth to the twenty-second movement. The ether cups fill on the deep side of the tank 24, and discharge on the shallow side, means being provided to compensate for changes of temperature. Specification 207,745, [Class 125 (ii), Bottle &c., Filling &c.], is referred to.

Filed: 1935-09-24
Abstract: A dihydroxy-alkyl benzene is added to textile lubricants to inhibit development of acidity and mould during storage of the lubricant or fabric.  0,8--0,575 per cent of hexyl-, propyl- or butyl-resorcinol, hexyl-hydroquinone or hexyl-pyrocatechol is suitable.  The composition may comprise glycerine, an oil such as olive oil, castor oil or tea-seed oil; starch, solubilized dextrine, and/or gelatine; other agents such as waxes or resins may be present.  The composition may be applied direct or in solution.ALSO:Threads, yarns, fabrics, and other textile materials are sized with a composition containing a dihydroxy-alkylbenzene.  The composition preferably has a starch and/or gelatine base and contains up to 1 per cent of hexyl-resorcinol.  The dihydroxy-alkylbenzene preserves the size and prevents bacterial or mould action.  Other suitable compounds are propyl and butyl-resorcinol, hexyl-hydroquinone and hexyl-pyrocatechol.  The size may comprise starch, solubilized dextrine, and/or gelatine; also glycerine, an oil, e.g. olive oil, castor oil or tea-seed oil; other agents such as waxes or resins may be present.  The size may be applied direct or in solution, by drawing yarns over rollers, wicks, discs or other means, e.g. as described in British Specifications 337,433, [Class 120 (ii)], 355,794, [Group IX], 359,477, 366,585, 390,861, 391,443.  392,904, 398,191, [all in Group IV], and 404,171, [Group IX], and in U.S.A. Specifications 1,929,192, and 1,972,924.  Yarn in package form may be treated with a solution of the size; or the size may be applied to fabrics by padding mangles.  In an example, cellulose acetate yarn is passed through a bath containing 4 parts of gelatine, 5 of dextrine rendered soluble in water, 2 of glycerine, 1/2 -1 of olive oil, sufficient water to make a milky solution, and ,25 per cent of hexyl-resorcinol, so that the yarn takes up 5 per cent of its weight of solid ingredients.

Abstract: 426,335. Fluid - operated signalling systems. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Continental Car Hire Co. (Continentale Wagon-Exploitatia Maatschappij Naamlooze Vennootschap) ; 75, Parklaan, The Hague) Sept. 27, 1933, No. 26641. [Class 118 (ii)] In a fluid-operated signalling system, the quantity to be indicated co-operates with a valve in a pipe line so that the pressure in the line is released when balance is reached, an indicator being provided to indicate the pressure and consequently the value of the remote quantity. As shown in the Figure, the variable quantity alters the rotary position of the inclined disc 11 and consequently varies the distance between the disc 11 and the valve stem 13. When the pressure in the pipe line is increased the bellows 12 expands and eventually causes the valve to open and release the pressure, which at this time indicates the value to be transmitted and is shown by indicator 8.
