Title: Improvements in or relating to the production of anhydrous magnesium chloride and tothe production of metallic magnesium therefrom
IPC: C01F5/32
Filed: 1945-12-08
Abstract: Anhydrous magnesium choride is produced by forming a slurry of ground pitch with finely divided magnesium oxide or a compound yielding it on heating, drying the slurry, forming the dried cake into lumps of convenient size, heating at 450-1000 DEG  C. in substantial absence of air until substantially all volatile constituents have been removed, and treating the resulting mixture of magneisum oxide and carbon with gaseous chlorine at 800-1000 DEG  C.  Magnesium hydroxide from seawater, the normal or basic carbonates and coal-tar pitch may be used.  Up to 5 per cent (of the magnesia) of sodium and/or potassium chloride may be incorporated in the slurry.  The magnesium compound preferably suffices to absorb all the agglutinants in the pitch and provides a magnesia to carbon ratio of 3 to 6 : 1 in the heated mixture. An equal weight of pitch and magnesium hydroxide may be used. Heating may be at 450-700 DEG  C. in a reducing atmosphere using direct heat or superheated steam.  Dried slurry may be briquetted with wet slurry to form the lumps.  The activity of the heated lumps to chlorine may be reduced by hydration or carbonation or restricting the decomposition to magnesium oxide.  Hydrogen chloride evolved in the chlorination may be absorbed in magnesia slurry and used in the process.  Magnesium chloride tapped from the base of the chlorinator may be electrolysed to magnesium.  The volatile constituents distilled from the pitch may be condensed and used as fuel, as a source of high boiling compounds, or instead of pitch in the process.

Patent GB-338281-A (GB)
Abstract: 338,281. Chilowsky, C. Jan. 18, 1929, [Convention date]. Oil gas.-In obtaining oil gas by partial combustion of heavy oil with superheated air and steam, the mixture is introduced into a hollow member in the combustion chamber with an out. let so placed that the flames are led by the member walls towards the inlet for unconsumed products and afterwards pass between the combustion-chamber walls and the hollow member. An atomized jet of oil, superheated steam and air issues from a nozzle 10 and impinges against a crucible 19 which may be of graphite or carborundum or non-oxidizing steel and in which eddy currents are set up. The flames are caused to pass in contact with the outer walls of the crucible, the products of partial combustion then discharging through a catalyst 12. Or the crucible may itself constitute a catalyst. For initially heating the apparatus solid igniting material may be supplied through an orifice 13, air being injected through the nozzle. A porous grooved brick 22 may be disposed in the crucible. A space may be provided above or below the crucible in which the partial combustion is completed. In modifications, the nozzle is disposed eccentrically of the crucible so that the, jet impinges obliquely on its wall or the nozzle may be arranged to project the jet tangentially along the inner surface of a cylindrical member replacing the crucible. The spraying nozzle may be supplied with air and steam or with mixtures at higher and lower pressures. In the form shown in Fig. 6, oil issuing from an axial tube 1 is sprayed by air and steam at 1-2 kg. per sq. cm, pressure from a nozzle 5. A further quantity of air and steam at a few hundred grams pressure is supplied by a pipe 7 to an annular chamber 8 terminating in a convergent nozzle 18 and communicating through small orifices 27 with a chamber 28 in the vicinity of the nozzle 5 which is situated at an adjustable distance from the nozzle 18. The two nozzles may be supplied with fluids at the same pressure or nozzle 5 may be disposed of. In another construction the nozzles are relatively close and the inner wall 26 of chamber 8 is dispensed with.

Abstract: 908,212. Valves. OIL CENTER TOOL CO. Oct. 4, 1960 [Dec. 28, 1959], No. 33971/60. Class 135. A relief valve for controlling fluid comprises a housing 11 having inlet and outlet passages 34, 32, a valve closure member 62 urged by a spring 82 into contact with a seat 40, the closure member being moved out of contact with the seat by a piston 54, detent means 132, 134 for preventing the piston from moving the closure member, and detent release means 102, 106 responsive to inlet pressure and adapted to release the detent means from the piston when the inlet pressure rises above a predetermined level. As shown, the piston 54 forms an integral part of a slidable member 50 which is loaded by the spring 82 thereby normally maintaining the valve 62 in contact with the seat 40. A pilot piston member 100 is mounted within the member 50 and is loaded by a spring 110. The detents, which comprise rollers 132 connected by links 134, are mounted in the member 50 and, in the closed position of the valve shown, the rollers co-operate with an annular groove 24 in the housing wall and with the cylindrical end 102 above the piston 100. In operation, when an increase in pressure builds up in the inlet 34, the pressure acts on the piston 100 via passages 94, 96 in the member 50 which moves upwardly thereby releasing the detent from the groove 24 and thus allows the member 50 to lift against the action of the spring 82 and open the valve 62. When the member 50 reaches its limit of travel, a spring- loaded detent 152, 154 engages with a groove 140 formed on the member 50 and thereby retains the valve in the open position.
