Abstract: 203,937. Stanton Ironworks Co., Ltd. and Wilson, P. H. Oct. 24, 1922. Centrifugal machines. - A pipe a is lined centrifugally with concrete &c., so that the lining h extends over the ends of the pipe, by mounting it in a cage f provided with a rolling surface c and sliding over the spigot end a ring d having a flange d'. The latter is held in position by bolts e attached to an angle-iron ring f, and determines the thickness of the lining, 'being distanced sufficiently from the end cf the pipe to allow the lining to cover the ends. The faucet end is similarly covered by means of a ring i having a packing of rubber &c. n, and 'held in position by centreing studs m. Iron sprigs r, s, Fig. 2, embedded in the ends of the pipe serve to hold the concrete in position.

Abstract: 504,296. Casting. JONES, E. F. Oct. 23, 1937, Nos. 28966/37 and 17089/38. [Class 83 (i)] Machines; moulds; castings, extracting.- Molten steel poured into a container 21 is displaced by a piston 22 into cavities 46 in a mould from which it is removed when set and preferably at a forging heat and rolled to the desired section. Fingers 49 on a plate 48 pivoted to a lever 32 coupled to a hydraulic cylinder 28 close the upper ends of the mould cavities and exert pressure on the steel during, setting. The container is mounted on a truck carrying a hydraulic cylinder for operating the piston through toggle mechanism. The mould is provided with pivoted hooks 40 for engaging projections on the container and with brackets 39 which may be engaged by hooks 37 on the lever 32 when it is desired to raise or, lower the mould. Before the metal in the container is set the mould is raised to break the connection between the metal in the mould and in the container. A series of trucks and moulds may be provided. Specification 381,790 is referred to. Moulds.-The mould, Fig. 5, consists of an outer casing 38, in halves, and an inner shell 44 separate from the casing and spaced therefrom by ribs 45 to form the mould cavities 46.

Title: Carburetor
IPC: F02M3/04
Filed: 1972-06-21
Abstract: 1395355 Spray carburetters J M J DE PONTAC 21 June 1972 [30 June 1971] 29122/72 Heading F1B The flow of fuel from a float chamber 2 to a fuel chamber 4, which communicates with the induction passage Venturi 3 through ducts 5, is controlled by a needle 35, coupled to an air-flow responsive valve 45 in the induction passage, and the pressure difference between the float and fuel chambers. The chamber 2 is subject to the pressure in the inlet 28' through a tube (43), Fig. 1 (not shown), and the chamber 4 is subject to the pressure at the carburetter inlet through a flowpath regulated by a bellows 51 subject to the inlet pressure and a control member 22 positioned is aligned recesses in first and second plates 14 and 15 of the carburetter. The tube 30 containing the bellows 51 is connected to an intake pipe supplying the inlet 28' and the valve 49 operated by the bellows controls the cross-sectional area of a calibrated opening in a disc 48. The member 22 is rotatable by a cable to close the flow-path to the chamber 4, through a recess 29 in the plate 15 and an opening 25 in the plate 14, for starting and partially close the flow-path when an associated enzyme is cold. To reduce the fuel flow on over-running a valve 54 subject to the pressure downstream of the carburetter throttle valve via a passage 60 connects the recess 29 to the chamber 2 by uncovering an opening 19. The chamber 4 is also connected to the inlet 28' through a tube 40 under the control of a valve 64 and a cylindrical valve 68. The valve 68 closes the flow-path from the tube 40 when the throttle valve is opened rapidly, the rod 72 coupled to the air valve 45 raising the valve 68 until sufficient fuel has flowed from the chamber 2 through the restricted passage 74 to permit the valve to move downwardly relative to the piston 77. The diaphragm 62 of the valve 64 is subject through a passage 66a to the pressure at an induction passage port 67 which is upstream of the throttle valve only when the throttle valve is closed or partially closed. The valve 64 opens the opening 32 in the flow-path in a range of throttle valve positions between idling and full load at which the valve 64 is closed. The carburetter may be supplied with air by a compressor (103), Fig. 8 (not shown), driven by an electric motor (104) which energized when the accelerator pedal (107) is depressed beyond a certain extent.

[Class 39(iii)] A cooking oven comprises a lagged container A with slideways E on the side walls, on which is slid an electrically-heated plate K with a plug J<1> engaging one of several sockets D arranged at different heights in apertures in the rear of the oven, and heatinsulated shelves M are slid into place above and below the heating plate so that a smaller oven of adjustable size is formed within the container. The top of the oven has an aperture B which may be closed by a slide or the top may be turned up as an anti-splash shield, so that when a heater is slid into the top of the container it forms a hot-plate; and when a heat-resistant shelf M is spaced slightly below, a griller is formed. The heater has a grid-like top and when detached may be placed on a stand for frying, toasting or as an electric fire. The sockets D are mounted on a vertical skeleton bracket N at the rear of the oven and the apertures are covered by sliding doors O when not engaged by a heater socket or are opened for oven ventilation. The heater comprises wire wound on grooved porcelain tubes J mounted on metal rods between metal strips H<1> in a metal frame, on the top and bottom of which slide removable heat-resistant cover plates G<1>.

Abstract: 1,139,530. Lasers. COMPAGNIE GENERALE D'ELECTRICITE. 27 June, 1967 11 July, 1966], No. 29603/67. Heading H1C. An autocollimation device for a laser comprises a beam splitter 13 having a surface 13a forming one of the resonant cavity mirrors of the laser and a surface 13b associated with an eyepiece 14. As shown the beam splitter is a biprism through which the laser radiation is passed to a beam expander 15 comprising two converging lenses. The central portion of the expanded beam is reflected from element 17, which is to be adjusted, and returns to the internal surface 13e of the biprism for reflection through an absorption screen 14a and focusing lens 14b to eyepiece 14 for direct observation. Surface 13d of the biprism is angled to prevent stray laser light 21a being reflected into the eyepiece. Alignment of the spot of light observed through the eyepiece with a reticule indicates correct alignment of element 17. Alternatively, alignment of two light spots may be employed.

Title: Preparation of vinyl ethers
IPC: C07C43/16
Filed: 1956-10-01
Abstract: In a process for making vinyl others from acety lene and alcohols free of acidic hydrogen in the presence of a strongly basic alkali metal compound as catalyst and 10-100% of an inert organic solvent capable of dissolving at least 18 volumes of acetylene at 0 DEG  C. and 1 atmosphere, the acetylene is absorbed at elevated pressures and a temperature not exceeding 14 DEG  C., and the mixture is then heated to 160-250 DEG  C. under pressure sufficient to keep the acetylene dissolved in the liquid phase.  The strongly basic catalyst may be an alkali metal oxide, hydroxide, alkoxide, cyanide or sulphide thereof, an alkoxide formed in situ being preferred; the alkali metal itself may be used to generate the catalyst.  Suitable solvents are certain ethers (including cyclic ethers), acetals and glycol and polyglycol ethers and N-alkyl-pyrrolidones: these are such as dissolve at least 20 volumes of acetylene at 0 DEG  C. and 14 at 10 DEG  C. (at 1 atmosphere). The ratio of solvent to alcohol should be 1 : 10 to 1 : 1 by weight, and preferably 1 : 7 to 1 : 1.5.  The acetylene may if desired by diluted with an inert gas, the pressure used for absorption being preferably 9.4-30 atmospheres and the temperature +10 to -30 DEG  C.  Examples show the preparation of vinyl ethers of ethanol, n-butanol, t-butanol, n-octanol, a mixture of C10-C14-C18 alcohols, cyclohexanol, benzyl alcohol, allyl alcohol, p-(t-octyl)-phenoxyethanol, ethanolamine and its N-methyl, N : N dimethyl and N-aminoethyl derivatives, 3-amino-1-propanol, ethylene glycol (giving monoand di-ethers) and b -vinyloxyethanol.  In general, R may be alkyl, alkenyl, cycloalkyl, cycloalkenyl, aralkyl or aralkenyl and many suitable alcohols are mentioned, some of which are substituted by alkoxy, alkylthio, chlorine, amino or heterocyclic groups, or combinations of such groups.  2-Methyl-1 : 3-dioxolane is a by-product when ethylene glycol is used.  The acetylene solvents used in the examples are dimethoxyethane, methylal and triethylene glycol dimethyl ether.  Other suitable solvents are listed.  The preferred range of reaction temperatures is 180-210 DEG  C.
