Title: Production of mutual solid solutions of titanium carbide and titanium monoxide
Filed: 1954-07-12
Abstract: Mutual solid solutions of titanium carbide and titanium monoxide wherein the molar ratio of carbide to monoxide is not greater than 1 are formed by heating to 1500 DEG  to 1800 DEG C. an intimate mixture of titanium monoxide with elemental carbon the molar ratio of carbon to titanium monoxide being not greater than 1, and continuing the heating until carbon monoxide evolution has ceased.  The titanium monoxide/carbide mixture is useful in the production of titanium by electrolysis.  The titanium monoxide may be prepared by electrolysis of the dioxide in a fused salt bath of one or more alkali or alkaline metal halides as in Specification 701,288, or by reacting titanium carbide and a metal oxide such as magnesia, lime or zinc oxide at 1300 to 1750 DEG C. as in Specification 711,077 or as in Specification 735,597 by heating titanium sesquioxide in the presence of titanium carbide at 1400 to 1700 DEG C. the sesquioxide being prepared by reacting titanium dioxide with a metal oxide such as lime, magnesia or zinc oxide at 1000 to 1200 DEG C., but preferably the titanium monoxide is produced according to Specification 754,889 by a two stage reduction of the dioxide with elemental carbon first to the sesquioxide and then to the monoxide.  The carbon employed is preferably lamp black or petroleum coke, suitably purified by calcination in a neutral atmosphere at 1370 DEG C.  The reaction is preferably effected in a graphite crucible lined with molybdenum sheet, the furnace either being swept with a current of inert gas or preferably, operated under a high vacuum such as 100 microns of mercury. The mixture of reactants may be briquetted but preferably is tamped into the reaction vessel and blow holes provided for gas evolution.  The termination of the reaction is indicated by the restoration of the degree of vacuum to its original value after the rising pressure due to gas evolution.  The reaction product which is a tightly sintered mass is not fused but if necessary after cessation of carbon monoxide evolution the product may be heated to a fusion temperature in excess of 1800 DEG C. and cooled and solidified to form a fused silvery grey crystalline mass.  If ilmenite is employed as an original source of the titanium monoxide residual iron in the titanium carbide/monoxide mixture may be removed magnetically.

Title: A fluid control valve for use in a friction device operating mechanism
Inventor: MAY WALTER CURT
IPC: B60T13/44
Filed: 1962-05-28
Abstract: 959,862. Clutch control; fluid-pressure brakes. WAGNER ELECTRIC CORPORATION. May 28, 1962, No. 20390/62. Headings F2E, F2F and F2L. [Also in Division G3] Actuation of a friction device, e.g. a brake or clutch, connected to a lever 12, Fig. 1, is effected by operating a pedal 16, which, through a wire or rod 15, moves a rod 51, Fig. 2, to the left, thereby carrying a piston 47 toward a slidable valve closure member 36 against a spring 50; this results in leftward motion of the valve easing 29, which, via a rod 14, initially actuates the lever 12, Fig. 1, to take up slack in the friction device. Concomitantly, the piston 47, Fig. 2, engages the closure member 36 and closes an exhaust passage 38 to isolate a chamber 33 therefrom. Further movement of piston 47 disengages the closure member 36 from its seat 31 and enables fluid from a reservoir 23, Fig. 1, and a compressor 24 to flow from a port 21, Fig. 2, to an outlet 25, which leads to a booster cylinder 18, Fig. 1, also connected to the lever 12. The cylinder 18 also serves to translate the casing 29, Fig. 2, relative to the piston 47 and closure 36 to move the seat 31 to a lapped position. When the pedal 16 is released the parts are returned to the positions shown by a valve spring 41 and spring 50 wherein the fluid supply is cut off by the closure 36 and the cylinder 18 is connected to exhaust by passage 38, which is also open to the interior of the piston 47 via a passage 54. In a modification, the booster piston 79, Fig. 4, control valve 36, slot 31 and piston 47 are disposed as a unit in the booster cylinder 74 which pivoted to a frame 67; the friction device actuating lever 62 is pivoted on a pin 83 between the clevis ends 82 of the booster piston-rod 81; the pedal-rod 63 is also received intermediate the ends 82. When the piston 47 unseats the closure 36, the pressure fluid acting on the piston 47 provides " feel " for the operator. Should the pressure fluid fail, the friction mechanism may be operated directly from the pedal.

Title: Manufacture of cobaltiferous azo-dyestuffs
Filed: 1952-08-13
Abstract: The invention comprises cobaltiferous azo dyes containing monoazo dyestuffs found in complex union, the ratio of metal atoms to dyestuff molecules being less than 1 : 1 (and preferably about 1 : 2); the monoazo dyestuffs are free from sulphonic acid and carboxylic acid groups and are of the formula:  <FORM:0719274/IV(c)/1> where R1 is a benzene residue free from sulphonic acid amide groups (the hydroxyl group being ortho to the azo linkage) and R2 is a benzene residue containing at least one sulphonic acid amide group.  There may be two different dyestuffs in the complex, the second being also of the above formula or of the benzene-azo-naphthalene type.  The metalliferous dyestuffs are made by normal metallization processes, preferably using less than one atom of cobalt per dyestuff molecule and/or carrying out the process in a weakly acid or alkaline medium. Suitable metallizing agents are cobalt acetate, cobalt sulphate, cobalt hydroxide, complex cobalt compounds of aliphatic dicarboxylic acids and o-oxycarboxylic acids and cobalt amine salts.  The metal-free starting materials are obtained from the appropriate diazotized o-aminophenols and 1-phenyl-3-methyl-5-pyrazolone sulphonamides. They need not be separated from the coupling mixture before metallization.  Preferred compounds are those which contain a sulphonamide group of the type -SO2-NX1X2 where X1 is hydrogen or alkyl and X2 is hydrogen, alkyl or aryl, particularly where X1 is hydrogen and X2 is hydrogen or C1-C6 alkyl.  The diazotized 2-aminophenol may contain chlorine or nitro substituents in the 4- and/or 6-positions.  The metallized products can be used for dyeing and printing silk, leather, wool and superpolyamides or superpolymethanes.  Examples show the production of cobalt complexes from (1) 4-nitro-6-chloro-2-aminophenol-->1-phenyl-3-methyl-5-pyrazolone -31-sulphonamide, (2) 4-nitro-2-aminophenol --> 1 - phenyl-3-methyl-5-pyrazolone-31-sulphonamide, and (3) a mixture of 4-chloro-2-aminophenol --> 1-phenyl-3-methyl-5-pyrazolone - 31-sulphonamide and 5-nitro-2-aminophenol --> 1-acetylamino-7-naphthol.  Other suitable components are mentioned. A further example shows the dyeing of wool with the product of (1).
