Title: Improvements in the manufacture and production of azo dyestuffs and their chromium compounds
IPC: C09B45/16
Filed: 1927-10-07
Abstract: 279,429. I. G. Farbenindustrie Akt.- Ges. Oct. 22, 1926, [Convention date.]. Monazo dyes are obtained by coupling the diazo compounds of 1 :2-aminonaphthol or its diazotizable derivatives with 1-naphthol-8-sulphonic acid. The products give on wool red shades which become grey on chroming. Chromium compounds of the dye stuffs are obtained by boiling, or heating to 120‹ under pressure, with chromium formate solution. In examples, diazotized 1-amino-2-naphthol-4-sulphonic acid and a nitrated derivative thereof are specified as first components; the chromium compounds therefrom produce greenish-blue and black dyeings respectively on wool.
Patent GB-722238-A (GB)
Title: Improvements in or relating to the production of rutile pigment
IPC: C01G23/053
Filed: 1952-10-23
Abstract: In the production of a rutile pigment from metatitanic acid or titanium dioxide in which a rutile promoter is added before calcination, the promoter is prepared by peptizing titanium hydrate with hydrochloric or nitric acid to form a sol, coagulating the sol by the addition of metatitanic acid and separating the coagulum from the peptizing acid, which may then be reused to prepare further sol, and also to prepare titanium hydrate by reaction with sodium titanate.  According to an example, the promoter is prepared by adding hydrochloric acid to titanium hydrate (obtained by neutralization of sodium titanate with hydrochloric acid) to form a slurry and thereafter heating slowly to boiling to form a sol in which the titanium hydrate is converted from anatare to rutile.  The sol is then added to washed metatitanic acid and the resulting coagulum deliquored and washed.  The hydrochloric acid is evaported, fortified and reused. The coagulum is added to washed sulphate hydrolysate before or during bleaching.  According to an example, the promoter is formed by adding hydrochloric acid to a cake resulting from neutralizing sodium titanate with hydrochloric acid.  The slurry formed is heated to boiling to form a sol.  To the sol is then added washed metatitanic acid and the resulting coagulum is deliquored to recover the hydrochloric acid for reuse, and washed.  The coagulum is then added to titanic acid prepared by treating a titanium sulphate solution with sodium hydroxide and working the precipitate.  The combined precipitate and coagulum are bleached by suspending in water in the presence of zinc and weak sulphuric acid, heating to 90 DEG C., cooling and filtering.  After bleaching, the product is calcined at 900 DEG C. in the presence of 0.23 per cent. potassium hydroxide and 0.07 per cent. alumina to give a rutile conversion of 95 per cent.

Abstract: 262,067. Bragg, C. S., and Kliesrath, V. W. Nov. 25, 1925, [Convention date]. Fluid-pressure. - A servo-motor for actuating motor vehicle brakes and like applications having a connection with the inlet manifold of an internal combustion engine wherein a vacuum is maintained on both sides of the piston in the naimad " off " position, is designed as a single acting unit, the return strode being effected by the retracting springs on the brakes or other actuated part. The controlling valve is carried by the pedal lever of a braking system. The servomotor cylinder 1, Fig. 2, is connected with the inlet manifold of an internal-combustion engine by a pipe 62 containing a non-return valve 63, and the piston 3 has a. hollow ported in which are valves 40, 41 arranged so that in the position shown in the drawing there is a vacuum on both sides of the piston. Movement of the pedal 88 results in air being admitted at 10, and 24, past the open valve 41, to the right-hand side of the piston, which is thereby moved and actuates through the link 9 a brake or like mechanism. Releasing the pedal results in the return of the piston under spring influence. The right-hand side may be placed in communication with the air or vacuum under the control of a valve 192, Fig. 8, the casing 191 of which is carried by the lever 188.
