Title: Improvements in or relating to the coating of metal surfaces
IPC: C23C30/00
Filed: 1936-06-24
Abstract: Bearing - members, e.g. journals, sleeve-valves, cylinders, or cylinder liners, which are made of hard metal and have been brought to the desired shape and smoothness are treated to convert the surface into a dense, amorphous, glass-like layer and are then coated with one or more layers of metal, each coating being treated to convert it into or to form at the surface a dense, amorphous, glass-like layer.  The coating metal may be the same as the base metal or may be any other hard metal, i.e. a metal with a melting point above 1200 DEG  C., which is soluble in or alloyable with the preceding layer.  To convert the surfaces from the normal crystalline state into the dense, amorphous, glass-like condition they are polished, burnished, hammered, rumbled, or subjected to a shearing stress, the treatment being such as not substantially to alter the configuration of the surfaces.  By this process an artificially run-in surface of non-corrodible metal such as chromium, nickel, cobalt, beryllium, manganese, or vanadium can be formed on a ferrous metal journal or other bearing-member.  The coatings may be deposited by electrodeposition, flashing, dipping, &c.

Filed: 1919-07-17
Abstract: 144,503. British Thomson - Houston Co., and Hastings, H. C. July 17, 1919. Electrode furnaces.-In a 3-phase furnace with more than two movable electrodes, one arc is regulated in accordance with its current strength, while each of the other arcs is regulated to maintain constant relationship between its pressure and that of the first arc. Regulation tending to maintain equality of electric pressure of the arcs is more sensitive than regulation by current strength, as the pressure variations are greater than the current variations in a 3-phase system. As shown, electrode 1 is adjusted by a motor under control of a contact-making ammeter C' connected to a series transformer. Each of the other arcs is regulated by a motor governed by a pair of differential pressure electro-magnets S<1>, S<2> or S<1>, S<3>, and relays A, B or C, D. Specification 136,500 is referred to.

Title: Process and apparatus for deoxygenating air by the combustion of sulphur or its incompletely oxidized compounds
IPC: C01B21/04
Filed: 1925-07-14
Abstract: 237,257. Chmura, T. July 14,1925. Nitrogen; sulphur. - Sulphur and substances containing sulphur, other than the higher oxidation products, for example sulphur dioxide, sulphuretted hydrogen, sulphur chloride, and sulphur ores are burned in air at atmospheric or higher pressure and the di- or tri-oxide produced, possibly mixed with elementary sulphur resulting from the decomposition of the dioxide into sulphur and the trioxide is separated under pressure rising to 1000 atmospheres, the residual nitrogen being rendered available for the synthesis of ammonia. To ensure the nitrogen being free from oxygen no more of the latter than that required to oxidize the sulphur to trioxide is introduced into the combustible mixture. Solid and liquid particles may be separated from the combustion gases by centrifugal force or by means of the silent electric discharge and water is removed both from the air and the combustion gases by means of sulphuric acid in order to prevent the subsequent deposition of corrosive acid liquor. Sulphur dioxide can also be absorbed and removed by means of alcohol, glycerine or mixtures thereof and sulphur trioxide by means of sulphuric acid. Residual uncondensed products may be removed at various stages during compression by means of adsorbents, by freezing out, or by chemical combination. By carrying out the combustion in one step or in stages in an internal-combustion motor or in a turbine the heat of combustion may be rendered available in order to meet the energy expended in the compression stage. When sulphur is employed as the fuel, it may be atomized from a nozzle by means of water under pressure heated by exhaust gases which may also be used for melting the sulphur and heating water when this is also introduced. The composition of the combustible mixture may be modified by the addition of oxygen as well as by the addition of inert gases. The parts of the engine exposed to the oxidation products are lubricated with liquid sulphur.

Abstract: 562,215. Wet separating. BERK & CO., Ltd., F. W., and SLACKE, R. L. R. Dec. 21, 1942, No. 18120. [Class 82 (ii)] In the washing of coal slurries from coal washers in which the slurry is treated by a sink-and-float process using as the heavy liquid a suspension in water of the shale present in the coal, two vessels containing water are connected by a syphon, the water in the first vessel being maintained at a substantially constant level and above the level of the water in the second vessel, the leg of the syphon dipping into the first vessel having a constriction above which coal slurry containing shale particles are supplied to that leg at a substantially constant pressure, so that a teetering suspension containing coal and shale particles is maintained above the constriction from which the coal particles are preferentially removed by the syphon. The syphon pipe 11 connects the second vessel 12 with a washer 7 having a constriction in the form of a spigot 8, above which is a sorting column 9, the latter and the washer 7 forming one leg of the syphon which dips into the first vessel 21. The discharge of the vessel 12 passes into a funnel 13 and a pipe 14 and the washer 7 is provided with a jigging diaphragm 15, and evacuating pipe 17 and a filling pipe 18 controlled by a pipe 19. The vessel 21 is connected to a dust elevator casing 22 for removing the shale and has water standing at a substantially constant level. A constant feed tank 1, fed by a valvecontrolled pipe 2, is provided with an overflow pipe 4, a slurry pipe 5 and connected by a feed pipe 6, itself connected tangentially to a water chamber 10 in the washer 7. In operation, the valve 20 is closed and the pipe 6 plugged. The washer is filled with water through the pipe 18 and as soon as water overflows through the pipe 11, the plug is removed from the pipe 6 and the valve 19 closed. When the vacuum indicated by the gauge 16 corresponds to the total height of the water above the level in the vessel 21, the valve 20 is opened fully. The slurry supply in the pipe 5 is now turned on which stops the supply through the pipe 2 and any excess overflows through the pipe 4 so that slurry is supplied at substantially constant pressure. A preliminary sorting of the coal and coarser shale is effected in the vicinity of the chamber 10, the coarse shale gravitating directly to the column 9 and the fine shale is prevented from rising and remains to form the heavy suspension. The coal is preferentially removed by the syphon pipe 11, a pipe 17 evacuating the large quantity of air contained in the slurry.
