Abstract: 947,083. Bottling. S.A. DE CONSTRUCTION DE MATERIEL D'ALIMENTATION. Feb. 6, 1961 [Feb. 8, 1960], No. 4331/61. Heading B8T. A filling head of a counter-pressure machine comprises a spring-loaded sleeve 12 sliding in a fixed block 14. At the start of filling the bottle raises the cone 1 against the sleeve 12 and forces member 6 up against a stop 11, whereby sleeve 12 is raised and causes lever 26 at the top of rod 28 to pivot and lift a valve 24 away from the end of a vent pipe 24 carried by the sleeve to admit counterpressure through the orifices 2 of nozzle 3. When counter-pressure is established in the bottle, spring 20 lifts the valve 5 away from its seat 7 and the liquid flows through orifices 17<SP>1</SP> and past valve 5 into the bottle. When the liquid level reaches orifices 2 the flow is reduced and finally a float valve 9 closes orifices 10<SP>1</SP> to shut off the flow. As the bottle is moved away from the nozzle, valve 23 closes the vent tube and during the initial downward movement of valve 16 a relief valve 33 is opened by a cam 32 to release the pressure from the neck of the bottle.

Abstract: 851,617. Building tyres. CONTINENTAL GUMMI-WERKE A.G. Feb. 14, 1958 [Feb. 15, 1957], No. 4832/58. Class 144 (1). The sidewall rubber covering strips 24 are each applied to a carcass 2, built on a tyre-shaped former 1, by means of an inflatable expansible deformable annular bag 20 on which the strip 24 is first laid, the bag 20 being subsequently positioned coaxially adjacent the former 1 and then inflated to expand and shape the strip 1 against the carcass sidewall. As shown the former 1 has a bored hub 4 to receive in each end a mandrel 5 which is telescopically mounted in a tube 7. Each tube 7 is slidably mounted in a pedestal 6 under the control of a power cylinder 8 and carries a fixed ring 12 thereon to abut and locate against the former 1. Each tube 7 carries also a sleeve 11 slidable thereon under the control of a further power cylinder 10, the sleeve 11 carrying a frusto-conical steel cage 13 which flares towards the former 1 and terminates in a cylindrical flange 14. A cylindrical diaphragm 20 is sealed at one end to the small diameter end of the cage 13 and its other end is sealed and clamped to the ring 12 so as to overlie a series of radially expansible segments 16 housed in a circumferential recess 15 of the ring 12, the segments 16 being expansible under fluid pressure introduced into the recess 15. A further recess 15 is provided in the ring 12 adjacent the former 1 to house an inflatable expansible annulus 19. In use, with the cage 13 and diaphragm 20 in the state shown in full lines on the right-hand side of the Figure, the sidewall strip 24 and a chafer strip 23 are positioned thereon as shown. The tube 7 is then moved to locate the annulus 19 on the ring 12 below the bead 26 of the carcass 2, the mandrel 5 being telescoped into the tube 7 against a spring (not shown). The annulus 19 is then inflated to stitch the chafer strip to the underside of the bead 26, and the diaphragm 20 is then inflated to the position shown by broken lines 27. At a predetermined bulging, sensed by a feeler mechanism, not shown, the cylinder 10 is actuated to move the cage 13 towards the former 1, the diaphragm 20 thereby being deformed first to the position shown at 28 and finally, with possible attendant relief of inflation pressure, into the position shown in the left-hand side of the Figure wherein it resiliently stitches the sidewall strip 24 to the carcass.

Title: Improvements relating to the mechanical finishing of textile materials
IPC: D06Q1/08
Filed: 1940-03-15
Abstract: 538,452. Treating textiles, with liquids resinous condensation products. CALICO PRINTERS' ASSOCIATION, Ltd., LANTZ, L. A., and INGHAM, J. S. March 15, 1940, No. 4889. [Classes 2 (iii) and 15 (ii)] Mechanically produced effects on textile fabrics and other textile materials, e.g. effects produced by embossing, glazing, schreinering, or calendering, are rendered permanent to washing by impregnating the materials with formaldehyde or a polymer thereof and another aldehyde, or a ketone, aldehyde-alcohol, or ketone-alcohol, . which is water-soluble and forms with formaldehyde a water-soluble precondensate, or impregnating with such a precondensate, drying and heating so as to obtain an insoluble resin on the materials. The mechanical treatment may be effected after the materials have been impregnated with the resin components or pre-condensate and dried but before the heating to form the insoluble resin. Aldehydes or ketones which may be used in conjunction with formaldehyde are acetone, methyl ethyl ketone, cyclohexanone, acetaldehyde, crotonaldehyde, aldol, and diacetone alcohol. The pre-condensate may be formed by allowing the components to react together at a slightly elevated temperature for a prolonged time in the presence of a mild alkali. Formation of the insoluble resin on the material may take place in presence of sodium, potassium, calcium, or barium hydroxide, or sodium or potassium carbonate. The process may be applied to yarns and loose fibres as well as fabrics. In an example, acetone and formaldehyde are condensed in presence of baryta. Viscose rayon taffeta is impregnated with an aqueous solution of the pre-condensate containing also formaldehyde and sodium carbonate. The fabric is dried at 70‹ C., embossed, heated at 140-150‹ C. for one minute, washed and dried. In another example, acetaldehyde is mixed with formaldehyde solution, paraformaldehyde, and caustic soda and the mixture is stirred and cooled for one hour. Cotton fabric is impregnated with a solution of the pre-condensate containing also sodium carbonate. The fabric is dried, conditioned, embossed, and heated to 170‹ C. Cyclohexanone, formaldehyde, and lime are mixed at 70‹ C. The mixture is cooled and the lime is precipitated with ammonium oxalate. The solution is filtered and saturated with potassium bicarbonate. Cotton fabric is impregnated with the solution, dried, embossed, and heated. Crotonaldehyde, formaldehyde, and barium hydroxide are allowed to react at 55‹ C. The mixture is cooled and paraformaldehyde and barium hydroxide are added. The barium is removed by adding potassium bicarbonate and filtering. Cotton fabric is impregnated with the solution.

Abstract: 1,160,974. Builder motion. JAMES MACKIE & SONS Ltd. 7 Dec., 1966 [4 Feb., 1966], No. 5074/66. Heading D1D. In a ring frame provided with a building motion consisting of a progressive upward movement and a superimposed reciprocatory movement derived from a rotary cam and having an auxiliary drive for driving the frame at a lower speed and for lowering the ring rail for doffing, the lowering movement is synchronised with the rotation of the cam by controlling the start of the lowering movement from a part moving in fixed relation with the rotary cam. As shown, ring rail 4 is reciprocated by a drive originating at a cam 11, the drive passing through a winch mechanism 17 whereby the rail is lifted by small amounts during the build to shape the packages. When the build is complete a switch 31 is operated by an element 30 associated with. the drive to the ring rails and a switch 83 in series with switch 31 is operated by a pin on a cam element 80 fixed to cam 11. As a result the normal machine drive is stopped, a lower speed motor started and then engaged to the main drive shaft through a pneumatically operated clutch. A pneumatic clutch 39 is then operated so that the delivery rollers drive the winch mechanism in reverse to accelerate the lowering of the ring rail. When the ring rail reaches its lowest point a portion of the cam 80 actuates a valve to cut off the air supply to clutch 39 and so return the winch mechanism to its normal condition. The undercoils are then wound beneath the bobbin and then a pin 81 on cam 80 operates a switch to stop the machine ready for doffing.
