Title: Improvements to filling-heads for counter pressure filling machines
Inventor: JOSEPH DENIS ROGER LOUIS
IPC: B67C3/26
Filed: 1960-06-08
Abstract: 931,846. Counter-pressure filling machines. ETABLISSEMENTS CHELLE. June 8, 1960 [June 9, 1959; Jan. 27, 1960], No. 20186/60. Class 125(2). A filling-head for a counter-pressure filling machine comprises an obturating member having ports 30, which act as guideways for projections 31 on a liquid valve 6, and a base 33 which is brought into contact with the underside of the projections 31, as shown in Fig. 3, in order to prevent air, trapped in the bottleneck after filling of the bottle, from passing the valve 6 in its open position and so entering the main liquid-container. The filling-head comprises a fixed nozzle 1 having a seating 5 for the valve 6 provided with a seal 7, the valve 6 being secured to a nozzle 8 having an air return port 10. A member 2 is slidable on a column 3 to enable the nozzle 1 to engage a bottle neck. A tube 11 integral both with the valve 6 and a guide-piece 12 is slidable within the stem 13 of a gas valve 14 accommodated in a tube 16 which slides, with the aid of a spring 21, on a tube 17 secured to the main container. The member 12 is urged upwards by a spring 24. The obturating member is secured to a spring 31a anchored at 32 on the tube 11 and its upward movement is limited by a stop 34 fixed to the tube 11. The tube 17 has ports 35, 36 for the passage of liquid from the main container. Operation. The gas valve 14 pressurizes a bottle on release of a control device bearing on a cap 25, thereby enabling the spring 21 to lift the gas valve sleeve 13 by means of an inward rib 19 on the tube 16. Gas pressure is passed underneath the valve 6 which is raised together with the parts 11, 12 and 34. Liquid from the main container flows through the ports 35, 36 and into the bottle. The pressure of the liquid maintains the obturating member in the position shown in Fig. 1, the ports 30 having allowed the valve 6 to move upwards relatively to the obturating member, Fig. 2 (not shown). The flow stops when liquid reaches port 10 in the nozzle 8, so creating an air lock. The obturating member is then raised by the spring 31a into contact with the stop 34 which brings the base 33 up against the underneath of the projections 31 on the valve 6 to make an airtight seal due to surface tension of the liquid surrounding the base 33. After the bottle is removed, the valve 6 falls on to its seating carrying the obturating member with it. Four modifications are described, Figs. 5-14 (not shown).

Title: Improvements in or relating to a method of forming mosaic elements
Inventor: CASSMAN HARRY
Filed: 1957-06-26
Abstract: In a method of forming mosaic elements on the end wall of a television pick-up tube in which a metal is deposited through a stencil to form the elements, a further metal is deposited through the stencil and the metals are caused by heating, to alloy so as to enable the elements to adhere more firmly to the support, and the stencil is then moved away, e.g. by tapping the end wall of the tube as described in Specification 740,751.  The alloy is formed by baking the envelope during the deposition of the second metal.  The first metal may be antimony and the second metal sodium, potassium, lithium or caesium.  A process is described in which after sodium is deposited on antimony elements and an alloy formed, the elements are photo-sensitized by successively depositing potassium, sodium again, further potassium, and caesium.  Finally, oxygen may be admitted. The antimony may be deposited by evaporation in the main envelope and the other metals generated in side tubes.

Title: Improvements in the recovery of vanadium
IPC: C22B34/22
Filed: 1926-08-23
Abstract: 269,780. Stevens, R. H., Norris, G. C., and Watson, W. N. Aug. 23, 1926. Drawings to Specification. Vanadium sulphates and oxide; ferric and zinc vanadates; zinc sulphate.-Vanadium present in sulphate solutions is reduced from the pentavalent to the tetravalent condition, as by means of ferrous sulphate or sulphite, or by zinc dust followed by ferrous sulphate, impurities, such as silica, ferric iron, and alumina, are then precipitated from the solution by addition of a basic material, and the vanadium is then converted to the pentavalent or trivalent condition to facilitate its subsequent precipitation as vanadate or oxide respectively. The invention is described as applied to the treatment of a solution obtained from a zinc-vanadium ore by leaching it as described in Specification 269,777. The solution is neutralized, after the vanadium has been reduced by the addition of a base such as zinc oxide, lime, or limestone, and the precipitate removed. Copper, if present, may be removed with the other impurities by the addition of a soluble sulphide after the solution has been neutralized, and phosphorus may also be removed at this stage in the manner described in Specification 269,778. Vanadium may be recovered from the impurity precipitate by subjecting the latter, in the form of a filter cake, to weak acid washes as described in Specification 274,297. The purified solution is next treated, either with zinc dust to reduce the vanadium to the trivalent state, or with acid to obtain an acidity of 2-5 grms free sulphuric acid per litre and then with manganese dioxide to reoxidise the vanadium to the pentavalent state. From the solution so obtained, preferably heated to 50‹ C., vanadium is precipitated by means of a base, a ferric compound being added when pentavalent vanadium is present, as described in Specification 269,779, and the vanadium being then precipitated as ferric or zinc vanadate, whilst when trivalent vanadium is present, vanadium trioxide is obtained. After the removal of the precipitate, the zinc solution is, if necessary, further purified before being subjected to electrolysis. A flow sheet for the application of the process to a zinc-vanadium ore is included in the Specification.

Abstract: 1,176,164. Drawing thermoplastic filamentary yarns. IMPERIAL CHEMICAL INDUSTRIES Ltd. 10 April, 1967 [11 May, 1966], No. 20815/66. Heading B5B. Apparatus for drawing yarns of synthetic filaments including a feed roll and a draw roll rotatable at a higher peripheral speed than the feed roll is characterized in that the peripheral surface of at least the draw roll which contacts the yarn is composed of metallic round or elongated microprotuberances of substantially equal height, the peaks of which are not sharp, being of flat or rounded form, and the direction of elongation being parallel to the roll axis, Roughening of surfaces for use in the invention may readily be accomplished by photo-etching methods. The term "microprotuberance" is defined as meaning protuberances which are measurable only by special techniques (such as using a "Talysurf" instrument) and which are larger than the protrusions of a highly polished surface, which protrusions are of the order of 10 micro inches (0À254 microns) or less in height. The microprotuberances may be microridges parallel to each other and to the roll axis and may be spaced at equal or at irregular intervals around the roll circumference. The cross-sections of the microridges may be triangular, the apices of the microridges being rounded or flattened. Alternatively the crosssections of the microridges may be square or rectangular. The filamentary yarn being drawn may consist of polyethylene terephthalate or nylon 66.

Title: Improvements in or relating to hydraulic speed governors
IPC: G05D13/00
Filed: 1953-07-29
Abstract: 743,747. Fluid-pressure servomotor control systems. MASSEY MACHINE CO. July 29, 1953, No. 21043/53. Class 135. A hydraulic speed governor for an engine, in which the throttle response for small speed changes is slow and for large speed changes rapid, comprises an engine driven sleeve 15, housed in a casing 14 and slidably mounting a valve piston 16 responsive to flyweights 20 carried on arms 21 pivoted to the sleeve at 22 and the valve at 24 so that increase in engine speed moves the valve downwards. Pressure liquid supplied by an engine-driven pump 25 is directed by the valve to one or other side of a double-acting piston 44 operatively connected to the engine throttle and returned therefrom to a tank 53. Pistons 61, 66 connected to the valve piston 16 and the piston 44 respectively, on increase in engine speed, move to decrease the volumes of chambers 62, 68 interconnected by a line 71 and, on decrease in engine speed, move to increase the volumes of these chambers. A line 73 connecting the chamber 68 to the tank has an adjustable throttle 75 and a cylinder 80 housing a piston 82 loaded on either side by centralizing springs 88, 89 and having an orifice in its head controlled by a non-return check valve 100. On a small increase or decrease in engine speed the rate at which the piston 44 moves and hence the engine throttle responds is dependent upon the rate at which liquid can leave or enter the line 73 past the throttle 75. The desired response being obtained by the setting of the throttle 75. In the event of a large increase in engine speed consequent upon a sudden decrease in load, the piston 82 moves rapidly upwards to increase the volume below it and so offset the decrease in volume of the chambers 62, 68 and permit rapid movement of the piston 44 and a rapid throttle response. This is followed by a momentary opening of the check valve 100 and the subsequent return of the piston 82 to its neutral position. In a modification, the piston 82 and the check valve 100 are housed in separate chambers. In another arrangement, the check valve is arranged to open in the opposite direction so that on a large decrease in engine speed consequent upon a sudden increase in load the throttle will be rapidly moved to restore the engine speed to its set value. Specification 666,991 is referred to.

Abstract: 938,031. Spray-producers. REVERTEX Ltd. June 8, 1962 [June 12, 1961], No. 21166/61. Class 69 (3). Two liquids, e.g. different coloured paints, are fed through flexible pipes 21, 22 and ducts 7, 8 into a mixing chamber 6, in a spray nozzle 1, and a gaseous medium, e.g. compressed air, is fed through a flexible pipe 23 and a duct 20 to an annular space enclosed between a deflector 11 and a cap 17. The deflector 11 is flanged at 14 and an air diffuser 16 is mounted in the cap near the nozzle outlet, slitted inwards from its circumference so that, in combination with the flange 14, it imparts motion to the compressed air such that the outlet of the nozzle is surrounded by an annular swirling stream. The liquids pass through a mixing ring 9 which has an 8-shaped aperture and serves to prevent bonding and misting. The mixing chamber 6 and outlet duct 15 are both short whereby, when the liquids impinge on a surface to be sprayed by them, they retain their identity to give a pattern effect of overlapping areas. The sprayed pattern may be varied by changing the mixing ring, as facilitated by a slot 10. The pattern may also be varied by varying the rates of flow of the liquids.
