Title: Improvements in or relating to pyrophoric lighters using liquefied gaseous fuel
IPC: F23Q2/173
Filed: 1954-02-23
Abstract: 739,940. Pyrophoric lighters. NATIONALE SOC. ANON. Feb. 23, 1954 [July 17, 1953], No. 5250/54. Class 75 (3). In a liquefied gaseous fuel lighter in which fuel passes to the burner through a porous material which is compressed by a tightening device to adjust the fuel supply, the porous material is located in a guide tube against a resilient support which yields under the action of the tightening device in such a manner as to slide the porous material in the guide tube to obtain a uniform compression in the material. The porous material 17 is shown located within a resilient tube 18 mounted in the guide tube 5. The tube 18 which may be of artificial rubber fits at one end on a spigot 21 of an axially movable member 22 and at the other end over the end of and against a spring- loaded collar 19 mounted on a tube 16. The compression of the porous material 17 and the resilient tube 18 is effected by rotating a member 31 rotatably mounted on the upper end of the tube 5 and attached to a washer 28 having a D-shaped hole 29 engaging a D-shaped portion of a screwed member 10. The member 10 on being rotated compresses the porous material 17 and the resilient tube 18 between the member 22 and the collar 19. The burner 11 carries a plug 27 of resilient material which closes a fuel passage 23 in the member 22 when the burner 11 is moved downwards by closing the lighter. A cotton or nylon wick 32 located in the tube 16 feeds liquefied fuel to the porous material 17, The initial compression of the porous material 17 and resilient tube 18 is effected by a screwed plug 15. The porous material 17 may comprise asbestos, cotton or nylon. In a modification, Fig. 3 (not shown), the resilient tube 18 is omitted and the compressible porous material 17 fills the space between the member 22 and the collar 19.

Title: Improvements in or relating to composite assemblies adapted for use in reinforcing portions of sheet material and for use in bonding portions of sheet material together
IPC: B32B27/00
Filed: 1953-02-26
Abstract: 727,844. Compound sheet materials. B.B. CHEMICAL CO., Ltd. Feb. 26, 1953 [Feb. 27, 1952], No. 5349/53. Class 140. A composite assembly for use in patching or joining plastic sheet material such as flexible vinyl resin sheeting comprises a thin flexible sheet of plastic material having firmly bonded thereto a film of a non-tacky, activatable butadiene-acrylonitrile copolymer adhesive containing a toughening agent, and also comprises a relatively stiff protective supporting sheet in strippable engagement with the adhesive film. The thin flexible sheet may be of vinyl chloride polymer, vinyl chloride-acetate copolymer, or vinyl chloride-vinylidene chloride copolymer, and may contain an ester plasticizer such as tricresyl phosphate, dibutyl, dioctyl or di-2- ethylhexyl phthalate. The toughening agent for the adhesive may be a vinyl chloride-acetate copolymer, chlorinated rubber, or a mixture of these. The adhesive, which may contain an ester plasticizer such as di-2-ethylhexyl phthalate, may be deposited on the supporting sheet from a solution in an organic solvent such as a mixture of toluene and methyl isobutyl ketone, the thin plastic film being applied to the adhesive layer after evaporation of the solvent. The supporting sheet may be a polythene-coated paper web, which, as shown, may be led from a roll 18 below a trough 14 where it receives a coating of a solution of the adhesive which is dried in the subsequent passage of the web through an oven 22. The dried, adhesivecoated web is united between rollers 24, 26, with a web of flexible vinyl resin film 28 that has been moistened with a mixture of toluene and methyl isobutyl ketone by a wick 34. The adhesive film originally applied to the paper web becomes strongly bonded to the vinyl resin film and remains strippable from the paper. Instead of applying a web of vinyl resin film to the adhesive-coated paper web, small sheets of vinyl resin film of differentcolour or design may be applied adjacent to one another. In use, the polythene-coated, protective paper sheet is stripped from the adhesive-coated vinyl resin film, which is pressed over the tear to be mended or the abutting edges of two pieces of vinyl resin film to be joined, after activation of the adhesive with a solvent, or with the use of heat, e.g. from a domestic iron.

Title: Electroflotation process
IPC: B03C5/00
Filed: 1972-02-25
Abstract: 1378884 Electroflotation ELECTRICITY COUNCIL 25 Feb 1972 [25 Feb 1971] 5445/71 Heading C1C [Also in Division C7] Finely divided solid particles (including waxes fats and greases), are separated from a liquid in which they are dispersed, e.g. an electrophoretic suspension or oil-in-water emulsion, by electroflotation comprising electrolysing the liquid, e.g. water to form gas bubbles using at least two horizontal electrodes disposed one above the other at the lower end of the vessel containing the liquid, the upper electrode(s) being perforated to allow the passage of bubbles generated at the lower electrode and the anode(s) comprising a coating of Pb-O 2  electro-deposited on to a substrate or Ti. The vessel may be provided with an inlet and outlet on opposite sides for a continuous liquid treating process, separated particles being retained in the vessel on the liquid surface. An anode may be formed by degreasing a Ti substrate, e.g. with trichloroethylene, removing the Ti oxide film therefrom by cathodization, e.g. in H 2 SO 4 , and electrodepositing PbO 2  thereon from a solution containing one or more lead salts so that the anode current density is increased during electrodeposition, e.g. first at 20 to 50 mA./cm.<SP>2</SP>, then at 50 to 100 mA./cm.<SP>2</SP>. The Ti substrate may be grid or gauge. An expanded stainless steel, mild steel or brass cathode may be used. For an electrophoretic suspension, migration of charged particles to a particular electrode may be prevented by shielding with a plurality of electrodes of opposite charge. A flocculating agent may be added to break an emulsion prior to electroflotation.

Title: Improvements in and relating to internal combustion engines of the sleeve valve type
IPC: F02B75/02
Filed: 1921-02-17
Abstract: 177,667. Lincoln, J. W. Feb. 17, 1921. Valves; valve-gear.-Fig. 1 shows a two-stroke engine. The cylinder has four ports controlled by a sleeve valve i, namely a compressed-charge admission port h, an exhaust port k<1>, a transfer port l<1> from the crank chamber, and an admission port m to the crank chamber. The exhaust port opens after the crank has turned through about 135‹, and at the same time a scavenging-charge of air or combustible mixture enters by the port l<1>. Soon after, a compressed charge flows through the ports h, until the crank has turned through 50‹ on its upward path, when the port closes and the charge is compressed. The engine shown has two cylinders which are supplied by a double-acting pump, the delivery being controlled by a piston valve g. The functions of the ports h, k<1> may be interchanged. The valve i is worked by an eccentric j<3>. A four-stroke engine has the ports in the cylinder similarly disposed, and the port k serves to admit the combustible charge into a vacuum in the cylinder during the suction stroke. The exhaust port opens when the crank has turned through 125‹, to be followed by the entry of the scavenging-air from the crank chamber, the port l in the sleeve being somewhat higher than in the two-stroke engine. The sleeve is worked by an eccentric revolving at half-speed.

Belt fasteners are fixed to a belt end by a ram 3a, linearly reciprocable normal to the belt face, carried by a head 3 movable across the width of the belt on transverse rods 2a, the belt end being gripped between plate members 5, 6. Belt fasteners, not shown, e.g. as described in Specification 1,003,512, are located in slots 15 in a comb 4 and retained by a rod 16, and the belt end, not shown, is butted against the comb 4, the plate 5 being lowered by moving a handle 12 in a helical slot in a fixed collar 11 to clamp the belt end. The ram 3a is lowered manually, or by a power-operated mechanism, by means of a rack-and-pinion drive to force securing elements, e.g. staples, held in a slot 14 in the plate 5, into the belt either singly or in groups. As the ram is raised again the head 3 may be automatically moved along the rods 2 ready for the next stroke, by a cam-operated pawl engaging notches in one of the rods 2a. In a modification, narrow clamping plates are used, and a separate fixed plate, which may in addition be integral with the comb 4, having a slot 14 for the staples, is spaced above an anvil supporting the belt end. In Fig. 2 (not shown), the comb 4 and attached slotted plate 5 can be pivoted clear of the head 3 and rods 2a for easy loading of fasteners and staples. In Fig. 4 (not shown), a modified head 3 in which staples on bars 31 in magazines 36 are urged toward the ram by end plates 37 and tension springs 38. As the ram 3a is lowered, sprung knife edges 33, 34 separate the two innermost staples and hold them against a sprung peg 35, sprung balls 39 preventing the staples from falling. As the ram continues downwards the staples are pushed into the belt, the knives 33, 34 and peg 35 being forced back flush with the ram face.

Filed: 1916-04-17
Abstract: 124,811. Chandler, L., and Metropolitan Carriage, Wagon, & Finance Co. April 17, 1916. Sights and methods of sighting. - Relates to anti-aircraft sighting-apparatus of the kind in which the correct elevation of the gun for any given range and angle of sight is shown by an indicator line intersecting a series of corrected range curves, and comprises an arrangement wherein the relation of the range curves to the indicator line is automaticallv varied as the sight is brought to bear on the target, and the elevation of the gun is determined by bringing an arm or pointer thereon to bear on the point of intersection on the appropriate range curve. As shown in Fig. 1, the corrected range chart h is attached to the sight-carrier d and is intersected by an indicator line k hanging freely or constrained by parallel links c, e, so that as the sight is directed on to the target, the indicator line remains perpendicular whilst the range chart moves in relation thereto. The gun is then elevated until an arm or pointer g, fixed to the trunnion or otherwise to the gun, passes through the point on the appropriate range curve, intersected by the indicator line. The parallel links c, e are connected by a cross-bar f terminating in brackets m, o, between which a wire constituting the indicator line k is strained by a screw n. The range-curve plate h is detachably secured to the sight-member by screws j, and is provided with a peripheral protractor scale h<2>, the intersection of which by the indicator line k shows the inclination to the horizontal of the line of sight. The corrected range curves may be continued to the left of the zero line to give depression readings j for targets below the muzzle horizon. A scale f<2> on the left-hand edge of the plate shows the angle of the gun axis with respect to the sight-line.

Title: Improvements relating to power plant in which a vapour is used to heat a gaseous working fluid
IPC: F02G1/04
Filed: 1948-02-26
Abstract: 643,598. Hot air or gas power plant. KAY, C. W. Feb. 26, 1948, No. 5819. [Class 7 (i)] Vapour, particularly steam, is used as an agent for heating a constantly gaseous working fluid, particularly air, the heating agent and working fluid flowing in separate closed circuits without mixing and the heating agent being alternately vaporized in a boiler and condensed without having been expanded, in a separate vessel in which heat is transferred to the working fluid which is then expanded to afford useful work and the heating agent is vaporized in the boiler and condensed in the separate vessel at substantially the same temperature and pressure without appreciable increase or loss of sensible heat and the temperature and pressure of the working fluid is raised substantially solely by the transfer of the latent heat of condensation of the heating agent. As shown pistons c, w, d each of which co-operates with a crank shaft g operate respectively in a hot air displacer cylinder a, a motor cylinder v and a cold air displacer b. The hot air displacer cylinder is connected to a heater m by a duct L and to a cooler j by a duct h while the cold air displacer cylinder b is connected to the opposite sides of the heater and cooler respectively by ducts n and k. If steam is used as the heating agent this steam direct from a boiler, not shown, enters the heater at o and water at the same temperature and pressure at the steain leaves at p. The cooling agent is suitably water which enters at q and leaves at n a throttle valve u is provided between the cylinder a and the motor cylinder v. Non- return valves s, t control the flow of air. In order to provide for reversing the engine a second pair of non-return valves may be fitted at the points where the ducts k I communicate with the cold and hot displacer cylinders respectively. One or other of the pairs of non-return valves is rendered inoperative by holding the valves off their seats. The valves s, t may be pressure actuated or mechanically controlled. In modification the cylinders a and v are combined in a single cylinder the piston of this cylinder having an area equal to the combined areas of the pistons c, w. Reversing may be provided for by known link motion associated with mechanism for controlling the valves or by mechanism for altering the angle between a motor crank x' and displacer cranks e' f. The air flow may alternatively be controlled by an oscillatory sleeve valve preferably in the cylinder b. The cylinders may be doubleacting in which case the heater and cooler will be duplicated. The cranks may be replaced by other mechanism such as links, rocker arms and eccentrics. A flywheel and/or a second motor cylinder similarly operated with its crank at 90 degrees to the crank x<SP>1</SP> and with a pair of displacers will be provided in practice. Pressure may be maintained by a small air pump driven from the main crank shaft.
