Title: Improvements in the manufacture and production of triarylmethane dyestuffs containing metal
IPC: C09B11/22
Filed: 1936-03-07
Abstract: Triarylmethane dyestuffs containing a hydroxyl group, and in ortho position thereto a further hydroxyl group or a carboxyl group are treated in substance with salts of chromium or copper. The resulting complex metal compounds of the dyestuffs when soluble in water may be used for dyeing wool, leather, silk and paper, and the sparingly soluble or insoluble products may be used for colouring lacquers, oils and waxes.  In examples: (1) the triarylmethane dyestuff prepared from 1-hydroxy-2-carboxynaphthalene-7-sulphonic acid and tetramethyldiaminobenzhydrol (cf. Specification 234,569, [Class 2 (iii)] is heated with a paste of chromium oxide in chloracetic acid; chromium fluoride, formate and sulphate may be used instead of the oxide; the dyestuff from sulphosalicylic acid and tetramethyldiaminobenzhydrol (cf. Specification 14621/90, [Class 2]) may be chromed similarly; by using copper sulphate the corresponding copper complex compounds are formed; (2) a triarylmethane leuco compound is prepared by heating 3 : 4-dihydroxybenzaldehyde and b -(2-methylphenylaminoethanesulphonic acid with alcohol and zinc chloride; by boiling with potassium bichromate solution, the complex chromium compound of the dyestuff is formed.

The spaced rings 7 are united by rods 8 passing through supports 9 projecting inwards from the rings. The rods and supports agitate the potatoes &c. as the drum rotates. The drum is rotated by contact with rollers 6 on the shafts 3 of the abraiding discs, the shafts being rotated by a motor 27 and belt 28. Water sprays are provided in the upper part of the casing. Filling and emptying doors 16, 17 are provided, and an outflow 19 leading to a screen box 20 and escape 22. The Specification as open to inspection under Sect. 91 describes also a machine wherein the abraiding discs instead of protruding into the drum are journalled within the drum and are driven by a fixed annular cogged wheel as the drum rotates. This subject-matter does not appear in the Specification as accepted.

Abstract: 512,618. Dyes. CHEMICAL WORKS, FORMERLY. SANDOZ. March 7, 1938, No. 7107. Convention date, March 8, 1937. [Class 2 (iii)] Dyes for wool or hair are made by coupling one mol. of the tetrazo compound of 4.4<1>- diamino-diphenyl-3.3<1>-disulphonic acid or of 2.7-diamino-diphenylene-sulphonedisulphonic acid in an acid medium with two mols. of the same or different 2-amino-8-naphthol-6-sulphonic acids of the formula in which R is H, alkyl or an'aryl radicle substituted by alkyl radicles in at least the two vicinal positions, whereby the azo groups enter in o-position to the amino groups. The coupling components may be used in the form of their O-arylsulphonyl derivatives, the arylsulphonic radicles being subsequently split off. R may be vic-xylyl or mesidyl, and the coupling may be carried out in acid solution in presence of sodium formate, sodium acetate, chalk, magnesium carbonate, sulpho-cyanides, xanthogenates or thiosulphates. In examples, (1) benzidine-3.3<1>-disulphonic acid sodium salt is tetrazotised and coupled with 2-amino-8- hydroxynaphtholene-6-sulphonic acid, or its 0-toluene-sulphonyl derivative' followed by saponification (violet shades on wool or hair), or with 2-mesidylamino-8-hydroxynaphthalene- 6-sulphonic acid (blue shades) ; (2) 2.7 diaminodiphenylenesulphone-disulphonic acid is tetrazotised and coupled with 2-amino-8-hydroxygraph-thalene-6-sulphonic acid (blue shades). The O-toluene-sulphonyl derivative of 2 amino-8-hydroxy-naphthalene-6-sulphonic acid is obtained by treating an alkaline solution of 2 - acetylamino - 8 - hydroxy - naphthalene - 6- sulphonic acid with p-toluene-sulphonyl chloride, followed by boiling the product with dilute mineral acid. Specification 13743/96, [Class 2], is referred to.

Filed: 1929-03-05
Abstract: 324,843. Dehn, F. B., (Mosinee Paper Mills Co.). March 5, 1929. Blow-down apparatus. - Scum and sediment collecting in a chamber 5 connected to the scum pipe and the bottom blow-down by pipes 7, 6 are blown off through a valve 12 automatically actuated in accordance with changes in the temperature or conductivity of the water in the chamber due to the accumulation of sludge. A temperature responsive element in the chamber is connected to a switch 16 which may be set to complete at any desired point a current through a relay 17 operating the blow off valve 12, which is thus opened when the temperature of the water around the temperature responsive element falls below a certain point due to the presence of sludge. The operation of the blow-off valve may be controlled directly by the heat responsive element. In a modification, the primary circuit of the relay 17 is completed through electrodes projecting into the sludge chamber, the current in the circuit being strengthened when the conductivity of the water is increased by accumulated sludge.

In order to suppress higher harmonics, the armature may be constructed in two identical sections e<1>, e<2>, Fig. 3, insulated from each other, and each provided with a commutator. The two sets of brushes are connected in series and the field winding i is connected across the outside terminaLs. By listening with a telephone t the brushes can be adjusted so that the harmonics in the windings are in opposition. The machine may also be provided with slip-rings and may function as a current transformer.
