Title: Improvements in and relating to the production of free carbon from hydrocarbons
IPC: C09C1/48
Filed: 1929-03-14
Abstract: 309,488. Lewis, G. C. April 11, 1928, [Convention date]. Natural gas, utilizing.-Free carbon is obtained from natural gas by heating it to a temperature at which cyclic hydrocarbons are formed, and below that at which free carbon is formed, removing the condensible materials and so producing a residual gas containing 15 to 70 per cent of free hydrogen, and incompletely burning this residual gas. If the raw material, such as casinghead gas, contains a considerable proportion of propane, butane, octane, &c., it is passed through chambers 11 containing adsorbent charcoal, silica gel, or an absorbent oil, so as to leave only methane and ethane; this is led through a conduit 12 and preheated by a burner 21 in the chamber in which the carbon is produced; the gas is then passed through a conduit 13 of a heat interchanger to coil 14 in a furnace 15. The temperature to which the gas is heated depends upon the material of the coil 14, the composition of the original gas, and the hydrocarbons it is desired to produce, and is usually between 600 and 900‹ C. After passing through the heat interchanging chamber 23, the gas flows through a series of chambers 17, which may be surrounded by cooling jackets 18, and which contain solid adsorbents such as charcoal, silica gel, or the like, or liquid absorbents, so that the benzene, toluene, naphthalene, anthracene, &c. are separated out. The residual gas is delivered to the burner 21 where, for carbon black, the frame impinges on a cooling surface, or, for lamp-black, the combustion takes place with insufficient oxygen.
Patent GB-416730-A (GB)
Title: Improvements in or relating to the manufacture of abrasive material
Filed: 1933-03-20
Abstract: Abrasive granules are treated, so that a binder such as glue will adhere to them more tenaciously, by applying a rough adherent coating to at least part of the surface of the granules.  The granules may be mixed with a slurry of vitrifiable material such as clays, bentonite, talc, cryolite, fluorspar, or feldspar, or mixtures thereof, the excess slurry is drained off, forced drainage, e.g. by vacuum, being used if desired, and the granules are then heated to burn the coating produced.  Fluxing materials such as borax, alkaline silicates, halides or hydroxides may be added to lower the fusion point of the coating material or to attach an infusible material to the granules. Temporary binders such as dextrin, powdered gums or sulphite cellulose liquor residues may be added to the coating material to increase its adhesiveness before the heat treatment.  In one method, abrasive granules such as fused alumina or silicon carbide are stirred with a slurry composed of 5 per cent slip clay such as albany clay, 2 per cent borax, and 93 per cent water, and after the granules have been wetted the excess slurry is drained off and the granules are dried at about 150 DEG  C.  The granules are then heated to about 900 DEG  C. to fuse the clay on to their surfaces.  The granules are next cooled to about 250 DEG  C., treated to remove loose foreign matter, e.g. by agitation in water, and dried, e.g. at 300 DEG  C. or a lower temperature where high capillarity is not required.  The product has increased resistance to flow which enables it to be more easily picked up by the glue when it is being attached to polishing wheels.  Specification 193,081, [Class 91], is referred to.

Title: Improvements in retractable landing gear
IPC: B64C25/10
Filed: 1932-03-23
Abstract: 388,226. Retractable undercarriages. GRUMMAN, L. R., 75, Ivy Way, Port Washington, New York, U.S.A. March 23, 1932, No. 8624. [Class 4.] An aeroplane comprises a body having an opening in the side, a collapsable undercarriage having a jointed compression member one end of which carries a wheel, and means acting upon one joint of the compression member to collapse the undercarriage and retract it into the body in such a manner as to cause the wheel to overlie the opening in the body side. A wheel 1 is mounted on an angular axle 2 held at its lower end by a pivoted yoke 3 and at its upper end by a similar yoke 4 pivoted to the body inwardly of and above the pivot of yoke 3. Movement of the wheel in its extended position is restrained by a compression strut having a lower portion 5 and an upper portion 6 pivoted together by an offset pivot 16. The upper portion 6 is formed as a yoke and pivoted to spaced transverse bulkheads as are the members 3, 4. Fixed to the upper end of part 6 is a pulley or similar device 10 which may be rotated by cables 11 from a winch or similar means within reach of the pilot. Clockwise rotation of the pulley when the strut is in the position shown at the right of Fig. 1 causes the hinge 16 to break inwardly, continued rotation causing the wheel to assume the position shown in the left side of the Figure. Reversed rotation of the pulley 10 would cause the wheel and strut to resume their original position. The strut part 5 may incorporate a hydraulic shock absorber. Specification 17433/15, [Class 4, Aeronautics], is referred to.

Title: Improvements in or relating to ordnance
IPC: F41A19/36
Filed: 1942-06-25
Abstract: 578,478. Ordnance. MOLINS, D. W., and MOLINS MACHINE CO., Ltd. June 25, 1942, No. 8765. [Class 92 (ii)] Relates to firing- mechanism for automatic guns having a sliding breech-block in which a fire-control device operates a trigger on the block through the medium of a firing lever, and consists in providing a catch device to prevent the firing lever moving under the pressure of the fire-control device until closing of the breech-block releases the catch. To diminish the pressure of the fire-control device on the sliding breech-block, a multiplying lever is included in the catch device. One form is shown applied to an automatic gun having automatic loading and ramming appliances and a sliding breech-block b opened on run-out by a cam-operated roller i and retained by the extractors for automatic closure on ramming the cartridge. The usual firing lever n, pivoted at o to the gun breech for operating the trigger w, on the breech-block, is actuated by the usual firing handle on the cradle when run-out is complete and a roller 14 on an extension Z of the firing lever n is engaged by a roller 13 on a bell-crank 12 operated by the firing handle on the cradle. According to the present invention, a second catch lever 16, pivoted at 17 and bearing against an extension 27 of a member g actuated during opening and closing of the breech, is also connected to the roller 14 by a link 19 near the pivot 17. The pressure of the firing handle or other firing device on the roller 14 is thereby conveyed to the lever 16 through a multiplying gear which diminishes the pressure of the lever 16 on the side of the breech-block. Further, the lever 16 prevents the firing lever from moving inwards to fire until the closure of the breech operates the member g and removes the extension 27 from the path of the lever 16. The firing lever has a projection u entering a recess v in the breech-block when this is closed. Fig. 4 shows in plan the means whereby the bell-crank 12 carrying the roller 13 is put under pressure at the end of run-out by a roller 11 on the bell-crank engaging a spring plunger 1 on the cradle. To permit of lanyard or like firing in place of automatic firing, a second manually-operated catch 22 may engage the plunger 1. The spring plunger 1 for effecting firing is alternative to the use of a firing handle for operating on the bell-crank 12. Fig. 7 shows a modification in which the catch-lever is in the form of an arm 37 pivoted on the axis of the roller 14 which engages a stop 38 under the pull of a spring 40 when the breech is open, thus preventing inward firing movement of the firing lever n. When the breechblock rises to closed position, a projection 41 on the block releases the arm 37 and permits firing.

Abstract: 1,091,957. Generators operating by electromagnetic interaction with fluids. SIEMENS SCHUCKERTWERKE A.G. March 2, 1965 [March 11, 1964], No. 8959/65. Heading H2A. In an MHO generator having helical plasma flow the magnet windings 8, 9 are excited with A.C. and the electrodes 6 forming the axial ends of the duct are electrically interconnected at the periphery of the duct by conductors parallel to the axis 7 of the helix. The conductors are formed by longitudinally extending segments of conducting material 11 spaced apart by insulating material 10 and forming the outer wall of the duct 1. By connecting the electrodes together a circumferentially directed Hall current I H  is produced which induces an output current in the magnet windings. The effect of centrifugal force is also reduced since the magnetic field produced by the circulating main current interacts with the current between the electrodes to produce a radially inwardly-directed force on the plasma.

IPC: H04N3/36
Filed: 1958-03-21
Abstract: 874,676. Television. BUSH & RANK CINTEL Ltd. May 27, 1958, No. 9089/58. Class 4(3) Television apparatus comprises a plurality of simultaneously operable image forming optical paths 3, 4 between a single point in a scanning device I and a like plurality of image planes 7, 8 to -which said paths are respectively normal, and means for causing the optical axis of the scanning device to coincide selectively with any of the paths. In the embodiment illustrated, the scanning device comprises a cathode-ray tube flying-spot scanner and kinematograph films are located in planes 7 and 8, the cathode-ray tube being mounted so as to pivot about an axis lying in the effective screen surface so that it may be moved between positions B and C where the scanned area is disposed perpendicular to the respective optical paths. Both paths remain operative, that to which scanner is perpendicular being free of optical distortion whilst the other is subject to keystone distortion and loss of edge focus. The apparatus permits a changeover of transmission from one kinematograph film to another, the film for transmission, being scanned in the distortion free manner whilst the other is scanned in a distorted manner but with sufficient accuracy for preview and monitoring purposes. The films are viewed by photo-electric cells 9 and 10 whose outputs are applied to a transmitter 15 and monitor 16 through change-over switches 13, 14 which are coupled to the mechanism for angularly displacing cathode-ray tube 1 and arranged so that the "undistorted" signal is always applied to the transmitter and the "distorted" signal to the monitor. In a second embodiment of the invention, Fig. 2 (not shown), the cathode-ray tube flying-spot scanner is replaced by a camera tube and the photo-electric cells by light sources. Reference is also made (without giving details) to an arrangement for use with images reflecting rather than transmitting light. One or two additional optical paths may be provided in a plane perpendicular to those shown in Fig. 1.
