Title: Process for producing acetylene
IPC: C07C2/80
Filed: 1964-08-04
Abstract: A process for producing acetylene comprises reacting at least one hydrocarbon with carbon vapour and rapidly cooling the reaction products to a temperature at which the decomposition rate of acetylene is negligible.  Preferably, the reaction takes place at atmospheric pressure using aliphatic hydrocarbons, e.g. C1-C5 paraffins, ethylene, propylene and butylene; cyclobutane, cyclopentane and cyclohexane and light petroleum naphtha fractions. Benzene, toluene and xylene may also be used. As shown in Fig. 2, hydrocarbon is fed via inlet pipes 19 and/or 20 into a carbon are provided by terminal electrodes 11 and 12, one or both of <PICT:1068913/C4-C5/1> which is made of carbon.  The product gas is rapidly quenched by spray means 23 using as coolants, water, gas or hydrocarbon oils. As an alternative to the arc, carbon vapour may be produced by resistance heating a carbonaceous material to a temperature at which carbon volatilizes.  The acetylene concentration (vol. per cent) in the product exceeds 25%.

Abstract: 855,831. Moulding-machines. DARWINS, Ltd. Sept. 18, 1959 [Sept. 27, 1958], No. 30945/58. Class 83 (1). A shell-moulding machine comprises a pattern-plate-support 1 mounted for rotation about a horizontal axis, a mix container 9 disposed mouth-upwards below the supportcarrying arms 12 extending parallel to but below said axis, vertically-guided bearings 10 on said arms, and means to move the bearings upwardly into positions coaxial with the axis of the support but clear of the rotation mountings 2 of the support, to bring the containermouth 16 into abutting contact with the support for rotation therewith. The patternplate-support, which contains heating elements 31, is rotated by a rack-and-quadrant mechanism 6, 7, actuated by cylinders 4, and the container is moved vertically by cylinders 14. An ejector-plate 33 is actuated by cylinders 34, which together with a weight 36, counter the weight of the container during immersion. A hood 17, having electric-heating elements 26, is movable by cylinders 19 into and out of position over the pattern-plate-support, a spring-loaded flap 21 being closed in the stationary positions by stops 23, 24, to prevent loss of heat. In the retracted position, the hood lies over a plate 30. The machine-controls are arranged for either manual or automatic operation.

Filed: 1937-02-05
Abstract: 484,074. Fluid-pressure servomotorcontrol systems. OHNRICH, A. Feb. 5, 1937, No. 30978. Convention date, Feb. 8, 1936. Divided out of 482,631 and addition to 454,637. [Class 135] An arrangement for controlling the speed of the driving engines of reciprocating conveyer shoots according to the parent Specification is modified by providing the pressure chamber 43 of the control pump 30, driven by a connection 152 from the shoot 163 or directly from the engine, with a further compensating or relief valve 202, in addition to the manually adjustable leak-off valve 100 which is controlled by the pressure of the driving medium in the engine cylinder 2 acting on a control piston 203 against a spring 208. Thus, if the load on the engine falls off, the engine tends to speed up and the driving pressure falls off, which results in the valve 202 closing to increase the control pressure to close the engine valve 19.

Title: Improvements in mercury, or other vapour electric lamps
IPC: H01J13/00
Filed: 1925-12-10
Abstract: 260,436. Reynolds, F. Dec. 10, 1925. Arc lamps.-A mercury or other metallic vapour lamp of the atmospheric type has at one end of the lighting tube a reservoir and a chamber for mercury or other liquid displaced from the reservoir, the arrangement being such that, when the lamp is working, the difference in levels of the liquid in the reservoir and chamber will not alter to any extent when the lamp is tilted. The reservoir C, Fig. 3, is connected with the lighting tube A, Fig. 1, and is surrounded by the displacement chamber D with which it communicates through an aperture c. The tube A has a restricted part a and an extension G heated by a coil to start the arc. When the lamp is not working mercury fills the tube and reservoir and also the chamber D to the level h. When the arc is started the mercury level falls in the reservoir and rises in the chamber to the position j. A cutout electrode e, mounted in a stopper E as described in Specification 189,993, short-circuits the coil after starting. In modifications (a) the displacement chamber is arranged inside the reservoir and (b) the reservoir and chamber are arranged side by side. Specifications 5596/08, 21834/08 and 172,666 also are referred to.

Title: Method of preparing liquid fuels for combustion
IPC: C10L1/32
Filed: 1926-12-09
Abstract: 286,386. Dehn, F. B., (Gasone Corporation). Dec. 9, 1926. Liquid-fuel supply.-A combustible mixture is obtained by subjecting the fuel and an expansible medium separately to a comparatively low pressure, mixing the fuel and the medium, subjecting the mixture to an emulsifying action, again subjecting the mixture to a further mixing and emulsifying action, subjecting the emulsion to a high pressure, and finally instantaneously lowering the pressure before combustion to permit expansion and explosive disintegration by projecting the emulsion into a chamber at a lower pressure. As shown, fuel, water, and air are supplied through conduits 10, 11, 12 and valve cages 13 to low pressure pumps 7, 8, 9, the pistons of which operate in unison. The fluids, compressed e.g. to 100 lbs. to the square inch pass through valve cages 21 to a mixing-chamber 27 delivering to an emulsifying apparatus E containing a series of fine screens. The preliminary emulsion passes through conduits 28, 29 and valve cages 34, wherein it is further emulsified owing to the tortuous path through which it is compelled to flow, to three high pressure pumps the pistons of which operate in succession. The emulsion, compressed e.g. to 3000 lbs. to the square inch, is then delivered through valve cages 35 to a chamber 50 communicating through a conduit 52 with a valve supplying the fire box of a boiler or the like. The conduit 52 is provided with a spring-loaded bye-pass valve 19 through which excess emulsion is delivered through a conduit 20 to a pipe 18 communicating with the valve cages 13.
