Title: A process for dyeing cellulose-containing materials using dyestuff containing arylurethane groups
IPC: C09B62/78
Filed: 1958-04-18
Abstract: Solid dyeings and printings on cellulose materials are obtained by applying thereto a water-soluble dyestuff of the azo, nitro or anthraquinone series containing at least one arylurethane (-NH-CO-O-aryl) group and fixing the dyeing or printing, in the presence of an alkali-metal or ammonium salt of an organic or inorganic acid and other agents used in dyeing and printing, by steaming or heating to an elevated temperature, or by treating in the presence of alkaline agents at lower temperatures.  A trans-esterification reaction occurs between the cellulose material and the arylurethane group in the dyestuff and the hydroxy-aryl compound is split off.  Specified salts and other agents used in the process are sodium or ammonium phosphate, sodium or ammonium acetate, sodium bicarbonate, ammonium chloride or sulphate, sodium chloride or sulphate, alginates, tragacanth, urea and dinaphthylmethane sulphonic acids.  When the fixing process is carried out at 20 DEG -60 DEG C. an alkali such as sodium hydroxide or carbonate is added.  When steaming or heating to 100 DEG -180 DEG C., sodium acetate may be added but is not essential. The dyed or printed material is preferably dried before fixing. The dyeings and printings may be treated with cobalt-, nickel- or copper-yielding agents.  In examples cotton and rayon fabrics are dyed and printed by the above process with the following dyes, the shades obtained being shown in parenthesis: metanilic acid --> 2- or 3-carbophenoxyamino-5-naphthol-7-sulphonic acid (orange or red); 1- carbophenoxyamino- 3-aminobenzene- 4-sulphonic acid --> 1-(41-sulphophenyl)- 3-methyl- or -carboxy-5-pyrazolone (yellow); 4 : 41-diaminodiphenylamine-3 : 21-disulphonic acid \sQ 2-amino-8-naphthol-3 : 6-disulphonic acid \sQ 1 : 3-diaminobenzene reacted with phenylchloroformate (black); 1-carbophenoxyamino-3-aminobenzene-4-sulphonic acid --> 2-carbophenoxyamino-5-naphthol-7-sulphonic acid (orange-red); 1-carbophenoxyamino-3-aminobenzene-4-sulphonic acid --> 1-carbophenoxyamino- or 2-amino- 8-naphthol-3 : 6-disulphonic acid (bluish red); 1-amino-(41-aminophenylamino)-anthraquinone-2 : 5-disulphonic acid reacted with phenyl chloroformate (blue); a copper complex of 2-aminophenol-4-sulphonic acid --> resorcinol \sM 1-carbophenoxyamino- 3-aminobenzene- 4-sulphonic acid (brown); 4 : 41-diaminodiphenylamine-2 : p  31-disulphonic acid reacted with 4-chloro-3 : 5-dinitrobenzoic acid and the product treated with phenyl chloroformate (brown).

Title: Process for the separation of dihydro-equilin and oestradiol
IPC: C07J1/00
Filed: 1938-04-26
Abstract: 509,075. Sex hormones. SCHERING AKT.-GES. April 26, 1938, No. 12448. Convention date, April 30, 1937. [Class 2 (iii)] Oestradiol is separated from dihydro-equilin by treatment of the mixture with a saponin, whereby the trans-oestradiol present is precipitated. The mother liquor contains chiefly the dihydro-equilin, together with a little cisoestradiol. The latter can be removed by crystallization. The preferred sapoin is digitonine, but other saponins such as solamine, cyclamine, and dioseine may also be used. It is preferred to carry out the precipitation in alcohol solution, but other water-miscible organic solvents may be used. The precipitation of the saponide takes place by long standing, but it may be hastened by evaporation of the solvent and treatment of the residue with a solvent for the materials other than the saponide. The saponide which is precipitated is preferably split up by treatment with pyridine, but other high boiling liquids such as xylene, other heterocyclic bases, also organic acid anhydrides such as acetic anhydride. In an example, an oestrone-equilin mixture is reduced with sodium in propyl alcohol to an oestradiol-dihydroequilin mixture and treated with an alcoholic solution of digitonine. The precipitate is filtered and treated with warm pyridine to isolate the oestradiol. The mother liquors are treated with ether to precipitate excess of digitonine, and the ethereal solution evaporated to give dihydro-equilin.

Title: Aircraft navigation instrument
IPC: B64D45/00
Filed: 1955-04-29
Abstract: 776,578. Attitude indicators for aircraft. SPERRY CORPORATION. April 29, 1955 [June 17, 1954], No. 12503/55. Class 4. An instrument for providing an indication of the attitude of an aircraft in pitch and roll comprises a housing 12 provided with a viewing opening 13 in a front wall 14 and cross pointers 10 and 11 mounted respectively on pivots 15 and 16 for movement with respect to a reference index 69 at the centre of the opening 13. The pointer 10 is actuated by a galvanometer 17 or similar means energized by the algebraic sum of signals proportional to the displacement of the aircraft from a radio course, the heading of the aircraft relative to the bearing of the course, and the roll attitude of the aircraft. The actuating means for the pointer 11 is energized by a signal corresponding to the displacement of the aircraft from the glide slope beam of an instrument landing system or from the altitude of the aircraft relative to a predetermined altitude, and a signal proportional to the pitch attitude of the aircraft. The backguard for the pointers 10 and 11 comprises a hemispherical member 25 having a horizon defining line 35 which sub-divides the member into upper and lower areas of contrasting colours. The member 25 is pivotally supported on an axis 28 by a shaft 41 mounted in bearings on a U-shape gimbal 27 pivotally mounted on an axis 32 by a hollow trunnion fitting 29 mounted in bearings in diaphragms 30, 31 of the housing 12. A shaft 43, axially movable within the trunnion 29, carries an L-shape fitting 45 at one end which pivotally engages a pin 46 on an arm 47 fast with the shaft 41 whereby axial movement of rod 43, caused by a cam 42, rocks the member 25 in a pitching sense about axis 28 against a restraining spring 51. The cam 42 is driven through a gear train 57-59 by a pitch motor 56 energized in response to a signal corresponding to the error between the position of the member 25 about axis 28 and the pitch attitude of the aircraft as established by a vertical gyro. Motion of gimbal 27 about axis 32 is controlled through a gear train 39 by a roll motor 38 energized in response to a signal corresponding to the difference in position between the position of gimbal 27 and the horizontal or roll gimbal of the above-mentioned vertical gyro. In order to provide the pilot with a measure of the angle of pitch and the angle of roll, the member 25 is provided with a pitch scale comprising a series of lines and dots 75 which denote 5 degree and 10 degree pitch intervals. When viewed as a whole the scale defines a rollattitude indicating line which co-operates with indices 76 on the wall 14. The zero position of pointer 11 may be adjusted by a knob 60 to take account of changes of loading of the aircraft. Specification 690,985 is referred to.
