Title: Improvements in or relating to bottles and like containers
IPC: B43L25/02
Filed: 1934-02-06
Abstract: 434,658. Dispensing liquids. LLEWELLYN, J. B., 4, Bonaparte Mansions, Westbourne Grove, Notting Hill, London. Feb. 6, 1934, No. 3932. [Class 102 (ii)] [See also Group XV] A device for effecting a removal of the liquid contents of a bottle or container by increments comprises a diaphragm for effecting displacement of a part of the liquid by compression of the air above the liquid content, a well for receiving the displaced liquid and a manually operable actuating device for positively moving the diaphragm in opposite directions. The well 4 is centrally mounted in the diaphragm 6, which is held fluid-tightly to the neck 2 of the bottle by means of a cap 10, which may be screw-threaded to engage a corresponding thread on the neck 2, or may be attached to the neck by turning over the free end of the downwardly-depending portion of the cap. Upon depressing the well 4 and the diaphragm 6, ink or other liquid is forced up the tube 12 into the well 4, and remains therein until the well 4 is raised again, when it flows back into the bottle. A second outer and movable cap 15 screws on to the cap 10 and is formed with a central aperture so that the inner edge of its face engages a recess 19 formed in the well 4. As the cap 15 is suitably rotated, the well and diaphragm are depressed together to fill the well. A valve washer 20 in the well 4 with apertures 21 offset relatively to the inlet tube 12 may be provided to prevent splashing of the liquid ; alternatively, the tube 12 may communicate with an aperture in the side wall of the well 4. The valve washer 20 may act as a stopper by the addition of a suitable plug inserted in the well and adapted to press on the washer. The thread on the cap 15 may be omitted and the necessary movement imparted thereto by such means as an inclined groove and pin connection between the inner and outer cap members, with an offset at the end of the groove to constitute a catch for holding the outer cap in its lower position. In a modification, the diaphragm is fixed to the top of the bottle neck by a non-removable cap, over which slides a larger cap formed with an aperture in which is fitted the upper end of the well. The inner and outer caps are formed with co-operating projections and recesses so that the outer cap and with it the diaphragm and the well may be depressed and locked in the lowered position by rotating the outer cap to engage its circular rim beneath the projections on the inner cap. Alternatively, the inner edge of the aperture in the inner cap may frictionally engage the outer cylindrical surface of the well and thus serve to hold the diaphragm and well in adjusted position. The well and diaphragm may be formed of rubber, or in part of synthetic resin or the like, or the diaphragm may be of rigid material resiliently attached to the well and/or the bottle. The diaphragm may be integral with the well, or if subsequently secured thereto it may be of thin metal resiliently connected to the well. Specification 434,690 is referred to.

Title: Improvements in or relating to the synthesis of ammonia
IPC: C01C1/04
Filed: 1921-02-02
Abstract: The residual gases from the synthesis of ammonia under conditions of hyper-pressure are re-circulated through the series of catalysing-apparatus by returning them to the inlet to the last cylinder of the hypercompressor.  The accumulation of inert gases, such as argon, is prevented by periodically allowing the residual gases to escape to atmosphere.  Specification 130,086 is referred to.

Title: Improvements to carburetters for internal combustion engines
IPC: F02M7/133
Filed: 1947-02-11
Abstract: 658,175. Spray carburetters. SOLEX. Feb. 11, 1947, No. 3993. Convention date, Feb. 15, 1946. '[Class 7(iii)] A carburetter of the kind suitable for use with an engine having more than four cylinders is adapted for an engine having four cylinders or less by the provision of corrector means to increase the fuel supply at full throttle, high speed operation. In Fig. 2, the mixture strength at full throttle is kept constant by. controlling the fuel flow through an auxiliary jet 47 by a needle 51 connected to a suction-actuated diaphragm 50 which also forms an acceleration pump. The chamber 49 is connected to a chamber 55 having orifices 56, 57 leading to the induction pipe on opposite sides of the throttle valve 7, the suction in which causes the filling stroke of the pump when the throttle 7 is closed and the desired correction of the mixture strength with varying speed at full trottle. In modifications the needle 51 is contoured to cut off fuel flow through the jet 47 when the throttle is partially closed, or the needle 51 may control the main jet 3. Specifications 603,296 and 610,046 are referred to. The Specification as open to inspection under Sect. 91 describes further embodiments in which a needle valve 9, Fig. 2 (Cancelled), is actuated by an air-flow responsive plate 15 or a suction-actuated piston or diaphragm to reduce the emulsifying air entering at 6, and also comprises the subject-matter of Specification 658,207. A suction-actuated valve may also control the flow of emulsifying air through a pipe connecting the air intake 12 to the lower part 5 of the nozzle. This subject-matter does not appear in the Specifiaction as accepted.

Abstract: 635,873. Distortable - container switches. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 11, 1948, No. 4042. Convention date, March 27, 1943. [Class 38 (v)] The thin metal operating diaphragm 2 of a high-voltage, high-frequency vacuum switch intended for controlling the radio circuits of aircraft or for use at sea, is coated with an alkyd resin to ensure perfect sealing of the diaphragm and render it resistant to the effects of salt-water spray and also to improve the switch insulation. The switch comprises a glass envelope 1 to which is sealed at 14 a metal terminal thimble 12 united to the diaphragm 2 by a flange 2a. A tubular arm 11 of copperplated steel is brazed to the diaphragm and carries a contact 9 of molybdenum, which is movable by the arm 11 to engage contact 7 or 8, also of molybdenum, mounted on terminals 3, 4 in re-entrant seals 5, 6. The switch is evacuated through the tubular arm 11 which is then sealed at 11a. The alkyd resin, a rosinmodified, oil-modified, glyceryl phthalate resin thinned by a solvent such as benzene or toluene, is applied to the exterior of the diaphragm 2 and over the flange 2a, and also to the exposed part of the arm 11 and portions 3a, 4a of the terminals 3, 4. The diaphragm, thimble, and terminals 3, 4 are of an iron-nickel-cobalt alloy having the same coefficient of expansion as glass, the exposed parts of the terminals being cadmium-plated to provide low resistance to high-frequency currents and'resist corrosion.

Abstract: 1,134,752. Inflatable fairings. MARSTON EXCELSIOR Ltd. 8 March, 1966 [29 Jan., 1965], No. 4047/65. Heading B7W. An inflatable fairing, positioned for example on an aircraft fuselage behind a retractable radar -probe, comprises inflatable cells grouped on one side of an inflatable cover which, when the cells are inflated forms, on its other side, the aerodynamic surface of the fairing. The cells and the cover are of inextensible material, such as rubber-coated nylon, " Terylene " (Registered Trade Mark), or glass fibre. As described, the cells are tubes 1 approximately aligned with the airstream when inflated, and disposed side by side between inner and outer covers 3, 2. The tubes are bonded to each other and the covers, and are slightly flattened (Fig. 5, not shown), to increase the contact area. Adjacent tubes are vulcanized, and the tubes are sewed or bonded to the covers. The fairing is made by laying the inner cover over a former, then laying over it the tubes and the outer cover, pressure being then applied to partly flatten the tubes. The tubes may have individual inflation valves or may be interconnected by holes with restrictor or non- return valves.
