Abstract: 384,015. Unscrewing bottle-stoppers ; chucks. BREWILL, A. W. L., Manor House, Castle Donnington, Leicestershire, and HOLLAND, I., 128, Waterway Street, Nottingham. Sept. 29, 1931, No. 27097. [Class 83 (iii).] A device for removing screw stoppers from bottles &c. c o m - prises a chuck provided with gripping jaws which are movable to grip and rotate the stopper &c., so as to remove the same, and means operating a u t omatically to eject the removed stopper &c. from the device. The bottle neck, carrying the screw stopper, is inserted, in an inverted position, through a guide member 19, which may be rubber lined, the head of the stopper contacting with the head 9 of a spring-pressed plunger 7 which is depressed against its spring 10, thereby moving inwardly a number of jaws 3, pivoted at 4 to a chuck 1, to grip the side of the stopper. On further downward pressure being applied to the bottle the chuck 1 moves downwardly against a spring 14, tail portions 18 on the jaws 3 thereby riding upwardly on a fixed cam surface 15 by which a second grip is applied between the jaws and the stopper. The spindle 2, carrying the chuck and slidably mounted in brackets 12, is constantly rotated by a belt &c. on a wheel 20, feathered to the spindle, to impart the necessary rotary motion to withdraw the stopper. In a modified arrangement the chuck 1 is not slidable and the spring 14, cam surface 15 and tail portions 18 are omitted, the first gripping action, by the depression of the plunger 7, being the only one provided. Automatic starting and stopping means may be incorporated, the spindle 2 only rotating when a bottle-stopper is being removed.

Filed: 1947-10-09
Abstract: 638,587. Thread tensioning. SULZER FRERES SOC. ANON. Oct. 9, 1947, Nos. 27156 and 27157. Convention dates, Oct. 10, 1946, and Sept. 2, 1947. Addition to 605,475, [Group IX]. [Class 74 (ii)] [Also in Group IX] A thread 1 is braked by pressing it against a taut flexible member which is made of hard material and owes its flexibility to its dimensions. In the form shown, a steel strip 75 is carried by levers 77, 78, one resting against a stop 89 while the other is loaded by a spring 86 anchored at 87; or the spring may be anchored to the lever 77. The levers rock on ball joints 79 to enable the strip to accommodate itself to brake shoes 10, 11; the shoes may be lifted alternately out of contact with the thread. The strip 75 may be initially straight, in which case bending stresses are induced in it by the clamping arrangement shown; or it may be first bent to fit the clamps 76 so as to be under pure tension. Instead of the strip 75, two strips may be used, anchored in a fixed clamp midway between the levers 77, 78, in which case the strips can be differently tensioned by attaching the spring 86 to points on the levers at different distances from their pivots 79; the braking effect then changes periodically as the shoes 10, 11 are raised and lowered. The strips may be in the form of endless belts as described in the parent Specification.

Abstract: 861,737. Treating potatoes &c. WEDDERSPOON PROCESSES Ltd. Sept. 3, 1957 [Sept. 5, 1956], No. 27224/56. Class 49. [Also in Group XXX] Timed movement of potatoes or other tubers through an elongated trough containing liquid, e.g. an aqueous preparation of an organic mercury compound, is effected by paddle members which are moved from one end of the trough to the other in spaced sequence, the tubers being delivered into the trough from a conveyer at a rate so co-ordinated with the rate of movement of the paddle members through the trough as to deliver the same quantity of tubers into each compartment between adjacent paddle members in the trough. With the apparatus of Figs. 2 and 3, paddles 3 at equallyspaced intervals on endless chains 4 traverse a liquid-filled trough 1, and the tubers are delivered on the upper run 6 of a conveyer C, which is transverse to the trough, and are diverted from this conveyer by arms 8 and 8<SP>1</SP> to fall into the trough compartments formed by the paddles 3. The paddles extend across the width of the trough and are provided with slits 14 for passage of liquid during movement of the paddles through the trough. A flexible apron 10 having its fixed edge near the edge of the upper run 6 of the conveyer C is engaged at its free edge by each successive paddle 3, so that tubers falling from the conveyer as a paddle is passing thereunder will fall on to the apron, and, after passage of the paddle and release of the apron, will fall into the liquid in the trough. The tubers leave the liquid by an incline a the end of the trough. Specification 861,738 is referred to.

Title: Process for the manufacture of vinyl chloride polymers and copolymers
IPC: C08F14/06
Filed: 1962-07-16
Abstract: In a process for the polymerization of vinyl chloride, optionally together with not more than 20 weight per cent of comonomer, the polymerization is effected in aqueous medium in the presence of an ammonium salt of a carboxylic acid containing 8 to 22 carbon atoms, and the polymer immediately before it has been completely dried is in admixture with a salt mixture containing an ammonium salt together with an alkali metal, alkaline earth metal, cadmium or lead salt of a carboxylic acid containing 8 to 22 carbon atoms, the cations in the salt mixture being 10 to 95 per cent ammonium and 5 to 90 per cent of the chemical equivalent of the metal.  Polymerization may be effected in the presence of the mixture, or in the presence of the ammonium salt as sole emulsifier and part of the salt converted to metal salt by the addition of a metal compound, e.g. an alkali metal or alkaline earth metal hydroxide, before drying the polymer. Many suitable comonomers are listed including vinyl and vinylidene halides, vinyl esters, unsaturated acids and esters thereof, and mixtures, e.g. of vinyl chloride, vinyl acetate and maleic anhydride.  Suitable carboxylic acids are caprylic, lauric, myristic, palmitic, stearic, oleic, linoleic, hydroxystearic, ricinoleic, epoxystearic, dihydroxystearic, hydroxyacetoxystearic, cyclohexyl propionic and p.-t.-butyl benzoic acids.  Polymerization may be effected in the presence of catalysts, e.g. benzoyl peroxide, lauroyl peroxide, 2,4-dichlorobenzoyl peroxide, acetylcyclohexanesulphonyl peroxide and azodiiso-butyronitrile; seed latices; and non-ionic emulsifiers, partial fatty acid esters of polyhydric compounds and polyethers. The polymers may be compounded with conventional stabilizers, fillers, pigments and plasticizers, e.g. di-n-butyl phthalate, di-2-ethylhexyl phthalate, diethyl sebacate, triethyl citrate and tricresylphosphate.  In examples vinyl chloride is polymerized in the presence of lauroyl peroxide and (1) ammonium salt of oxidized oleic acid and the polymer treated before drying with sodium hydroxide; (2) a mixture of ammonium laurate and sodium laurate; and ammonium dihydrostearate and the polymer treated before drying with (3) calcium hydroxide and (4) sodium acetate; and vinyl chloride and vinylidene chloride are copolymerized in the presence of lauroyl peroxide and (5) ammonium laurate and sodium laurate.  The polymers are compounded with dioctyl phthalate to form plastisols.

Abstract: 672,969. Valves. CLIMAX ROCK DRILL & ENGINEERING WORKS, Ltd. Nov. 21, 1949 [Oct. 21, 1948], No. 27399/48. Class 135. In a piston slide valve having a ported liner and a landed piston slidable therein, at least one of the piston lands has a seal between it and the liner comprising a pair of rubber rings mounted in grooves and so spaced that on one of the rings passing a port the other still makes sealing contact. As shown, for controlling the supply and exhaust of pressure fluid to and from a double-acting cylinder, the valve comprises a casing 1, Fig. 1, having ports 2 ... 6 and an axial bore 7 housing spaced liners 8, 9 within which is slidably mounted a piston valve 19 having lands 20. A sealing ring 21 of synthetic rubber is mounted in a groove in each of the outer lands whilst a pair of similar rings are mounted in grooves in the ports' inner lands and so spaced apart that on movement of the piston to control radial ports 12, 13 in the liners 8, 9 a seal is formed at all times, between the piston and the liner even when one of the rings is passing its associated port. The piston is biased to the right by a spring 22 and operated by a pivotally mounted lever 26 having a projection 27 pivotally mounting a rod 28 engaging a recess 29 in the end of the piston. A projection 31 on a plate 32 secured to the lever 26 engages stops on a plate 24 secured to the casing to limit the movement of the piston in both directions. In a modification, the plate 32 is replaced by a plate 46, Fig. 3, of different shape formed with an arcuate slot 50 engaging a pin 49 fixed on the lever 42 and connected by a spring 48 to a casing plate 43. In this arrangement, on continued anti-clockwise movement of the lever 42, after the pin 49 engages the upper end of the slot 50, the lever 42 and plate 46 both move against the spring 48 to move the piston 19 into a third position. In another arrangement, the piston 19 is operated by a cam engaging a roller mounted on the piston. In a further modification, the right-hand end of the casing is fitted with an adaptor to which compressed air is supplied to or exhausted from the cylinder to operate the piston. In a still further arrangement, adaptors may be fitted to both ends of the casing and bleed passages in the piston connect the central pressure port 3 to spaces at either end of the piston. The pressure in these spaces may be relieved to atmosphere by solenoid-actuated pilot valves to operate the piston. The casing may have three ports instead of five to control a single-acting cylinder.
