IPC: F22B37/40
Filed: 1919-10-23
Abstract: 160,207. Kermode, J. J. Oct. 23, 1919. Oil supply fittings.-In liquid fuel burners supplied with compressed air, as fitted to steamgenerators, ranges, &c., the supply of fuel is stopped automatically in the event of failure of the air supply. The fuel is delivered to a control-tank 2 which is connected at the top by a pipe 4<c> to the compressing-air pipe 4 supplying the burner or burners 1, and is fitted with a burner supply pipe 5 extending from nearly the bottom of the tank and passing well above the fuel level in the tank. The pipe 5 is fitted with am open-ended stand-pipe 5<c> in which the fuel rises to a height corresponding to the head due to air pressure in the tank, so that, if the air pressure fails, syphoning is prevented by the admission of air to the pipe 5. Instead of the stand-pipe 5<c>, a cock, opened automatically when the pressure falls, may be fitted on the pipe 5. The fuel and air pipes are fitted with control valves 5<a>, 4b, 4d, and a surplus air pipe 4<f> fitted with a control valve 4<g> is also provided. The liquid fuel may be preheated by leading the pipe 5 through the flues of the ranges &c. or by other means. The burners may be of the type illustrated in Specifications 15269/04, [Class 51, Furnaces &c.], 12040/07, [Class 126, Stoves &c.], 4003/12, and 26418/12.

Patent GB-633972-A (GB)
Title: Preparation of alkynyl-alkenylcarbinols
IPC: C07C29/42
Filed: 1947-09-26
Abstract: Alkynyl-alkenylcarbinols are prepared by reacting a haloepoxyalkane of the formula <FORM:0633972/IV (b)/1> where X is Cl or Br, and R, R1 are H, CH3 or C2H5, in liquid ammonia with an alkali metal derivative of an alkynyl hydrocarbon of the formula Y-C­CM, where Y is H or an alkyl or aryl group, and M is an alkali metal. Preferably, reaction is effected at the boiling point of the ammonia using a molar excess of the alkali metal derivative.  An atmosphere of inert gas such as nitrogen may be used.  Reaction times are suitably 5-18 hours. Suitable alkynyl hydrocarbons are acetylene, phenylacetylene, and 1-hexyne, and suitable haloepoxyalkanes are epichlor- (or brom-) hydrin, and brom-2,3-epoxybutane.  In examples: (1) sodium is dissolved in liquid ammonia in presence of ferric nitrate to form sodamide, the solution being saturated with acetylene to give sodium acetylide, epichlorhydrin then being added while cooling, ammonium chloride added, ammonia evaporated, and pent-2-en-4-yn-1-ol extracted with ether; (2) epibromhydrin is reacted similarly, yielding the same alkynyl carbinol and a compound of unknown structure; (3) 1-brom-2,3-epoxybutane yielded hex-3-en-5-yn-2-ol, and 2-(2,3-epoxy-1-butoxy)-hex-3-en-5-yne; (4) phenylacetylene is used in a similar process to (1), yielding 5-phenylpent-2-en-4-yn-1-ol; (5) 1-hexyne similarly gives non-2-en-4-yn-1-ol.  The products may be partially or completely hydrogenated to give, for example, a dienol; treated with mercury sulphate and sulphuric acid to give a furane derivative; with an amine and formaldehyde to effect the Mannich reaction; oxidized to the corresponding carboxylic acid, for example with chromic acid in acetone; subjected to oxidative coupling in presence of cuprous ammonium chloride to give the p  di-yne-glycol which may be hydrogenated to the corresponding alkane diol; or condensed with formaldehyde in presence of cuprous hydroxide.

Title: A fluid-flow control valve
IPC: B60T15/04
Filed: 1965-06-23
Abstract: 1,080,937. Fluid-pressure brakes; valves. WAGNER ELECTRIC CORPORATION. June 23, 1965 [Sept. 10, 1964], No. 26683/65. Headings F2F and F2V. A vehicle brake-valve has an inlet port 19, Fig. 2, an outlet port 20 leading to the brake chambers, an exhaust port 31 and an emergency port 21; the inlet port 19 is connected to a reservoir charged by a compressor via a check valve whilst emergency port 21 is connected by a manual valve to an emergency reservoir also supplied by the compressor, which manual valve may be moved to another position in which it isolates the emergency reservoir from port 21 and vents the latter. With the manual valve closed the emergency fluid-pressure lifts a piston 49 disposed in a reaction piston 37, against a spring 56. When the operator actuates the brake pedal a metering spring 48 is compressed and urges the reaction piston 37 downwardly so that a tubular extension 54 of the piston 49 abuts a closure member 35 to close-off both the outlet port 20 and the exhaust passage 55 of piston 49 from the exhaust port 31. Further downward movement of the reaction piston 37 unseats the closure member 35 and interconnects ports 19, 20 to energize the brakes; when the force created by the outlet pressure acting on the reaction pistons 37 equals the operator-applied force the piston 37 moves upwardly to provide a lapped position of valves 54, 35. Should the emergency pressure fail the spring 56 will urge the piston 49 downwardly to close valve 54 and open valve 35 to apply the brakes. If a mechanical failure prevents the application of movement to piston 37 the brakes may be applied by operating the manual valve to vent the emergency pressure beneath the piston 49. In a modification the valve 54 (Fig. 3, not shown), is formed on the end of an extension of the reaction piston 37 within which is slidable the tubular extension of the emergency piston. In another modification (Fig. 4, not shown), the emergency piston has a part open to the outlet pressure so compensating for any loss of emergency fluid and providing a metered supply of fluid to the brakes even in emergency conditions.

Abstract: 404,094. Motors. GRASEBY, R. C., Venner Works, Kingston By-Pass Road, New Malden, Surrey. Sept. 26, 1932, No. 26691. [Class 35.] Rotary machines.-A self-starting synchronous motor with unshaded poles consists of a soft iron stator .adapted to be supplied with single-phase current to cause adjacent poles to be of opposite polarity and a polarised rotor of which adjacent poles are of opposite polarity ; the rotor and stator are relatively unbalanced either magnetically or dynamically, the air gap being uniform, and the weight of the rotor is such that it will start rotating when current is supplied to the stator coil, a mechanical check being provided to prevent rotation in one direction. The slator consists of two rings 3, 5 formed with teeth 9 and embracing the coil 11. In the form shown the rotor consists of a permanent magnet 13 with poles 15, each pole being subdivided into two sub-poles 16, 17. Magnetic unbalance in this construction is obtained by removing a small amount of material from one side of some of the poles. Alternatively, the weight of the rotor may be unbalanced. The mechanical check comprises a double cam 2a on the spindle 21 co-operating with balls 31 and a fixed collar 25. In a modification, the check acts on a second shaft geared down from the rotor spindle.
Patent GB-482659-A (GB)
Title: Improvements in or relating to retorts and retort furnaces
IPC: C22B19/14
Filed: 1936-10-01
Abstract: Walls.-In a retort furnace a movable section is provided in the outer wall, through which horizontal pressure can be applied to the walls of the retort for the purpose of preventing vertical cracks or joints from opening.  As shown in Fig. 1 in connection with a vertical retort built up of superposed sections 3 of consistently greater length than breadth, one or both end walls 5 of each section contact with bricks 7, 8 which are pressed inwards by adjustable springs 9, 10.  The pressure may be exerted by a pneumatic piston, an hydraulic piston acting through a spring, or by a weighted <PICT:0482659/III/1> <PICT:0482659/III/2> <PICT:0482659/III/3> <PICT:0482659/III/4> lever having on one arm a roller bearing against the brick; and to allow vertical movement of the bricks due to expansion, rollers may be interposed between the spring pressure means and its fixed abutment on the setting.  In the construction shown in Fig. 10 a weighted lever 14 acts on a pair of bricks 7, which may be in contact as shown, or slightly spaced, through a wheeled carriage member 15.  The joint between the bricks 7, 8 and the setting may be stepped to minimize leakage of gases.  In one construction of setting two retorts are arranged in line on opposite sides of an abutment wall, and pressure is applied from both sides of the setting.  In another construction, Fig. 13, portions of the two side walls of the retort are made integral with portions of the end wall, which are angled as shown, and the brick 7 is shaped so that it will tend to close the tongue and groove joint 51. When the side walls of the retort are constructed of tiles, pressure may be applied separately to the two walls as shown in Fig. 17.  The gaps between the retort walls and the setting are sealed by loose granular material poured into grooves 35. The Specification as open to inspection under Sect. 91 includes also a construction in which the end wall of the retort, consisting of wedge blocks inserted between tapered block extensions from the side walls, forms part of the outer wall of the setting, pressure being applied to all the blocks forming the end wall.  This subject-matter does not appear in the Specification as accepted.
