Title: Manufacture of thioindigoid dyestuffs
IPC: C09B7/10
Filed: 1944-10-25
Abstract: Thioindigoid dyestuffs are prepared by combining a mixture of a 6-halogenated and a 4-halogenated-7-methyl-3-oxythionaphthene, if desired in the form of reactive 2-derivatives, with a component suitable for the production of thioindigoid dyes.  The mixture of 6-halogenated and 4-halogenated derivatives referred to may be obtained by chlorinating o-nitrotoluene, whereby a mixture containing 6-chloro-and 4-chloro-2-nitro-1-methylbenzene is obtained, and the product (which contains about 66 per cent of the 6-chlorinated derivative) is reduced, diazotized, reacted with a xanthate and converted to a mixture of the corresponding oxythionaphthenes in known manner.  The mixture of oxythionaphthenes may be converted to a dyestuff by combining with a thioindigoid component, e.g. the p-dimethylamino-anil of 4-methyl-6-chloro- (or 6-bromo)-thionaphthene quinone, of 5 - chloro - 4,7 - dimethyl-thionaphthene quinone, of 5-chloro-7-methyl thionaphthene quinone, of 1-chloro-2,3-naphth-thioisatin, or of 2,1-naphth-thioisatin. Alternatively, the mixture of 6-halogenated and 4-halogenated-7-methyl-3-oxythionaphthenes may be converted to the reactive 2-derivatives, e.g. the p-dimethylamino anils, and condensed in that form with an oxythionaphthene.  The dyestuffs are suitable for dyeing and printing silk, wool, cotton, linen, artificial silk and staple fibres of regenerated cellulose and superpolyamide fibres. The dyestuffs may be converted to leuco-ester salts by known methods. In examples: (1) the mixed 6- and 4-chloro-7-methyl-3-oxythionaphthene is condensed with 4-methyl-6-chloro- (or bromo)-thionaphthenequinone-p-dimethylamino-anil; (2) the mixed oxythionaphthenes of (1) are condensed with 5-chloro-4,7-dimethyl-thionaphthenequinone-p-dimethylamino-anil; (3) the mixed oxythionaphthenes of (1) are condensed with the p-dimethylamino-anil of 1-chloro-2,3-naphth-thioindoxyl, or with the p-dimethylamino-anil of 2,1-naphth-thioindoxyl; (4) a mixture of cotton and regenerated cellulose s aple fibre is dyed in a bath containing the dyestuff of example (1) vatted by the addition of sodium hydrosulphite; (5) the dyestuff of example (1) is made into a printing paste by mixing with wheat starch, water, tragacanth, British gum, potassium carbonate, glycerine and sodium formaldehyde sulphoxylate.

Title: Improvements in methods of producing foam
IPC: B01F3/04
Filed: 1936-08-27
Abstract: A lasting foam is produced by dissolving a foaming agent in a mobile liquid such as water, adding solid particles, of more than colloidal dimensions, which do not react with or dissolve in the liquid, and then dispersing a gas in the liquid so as to form the foam and disperse the solid particles in the foam.  The particles may consist of finely ground alumina or, for fire-extinguishing, of ground limestone or sodium bicarbonate.  The solid particles may have fertilizing, weed-killing, or pest - combating properties; for example, sulphur or copper arsenate powder may be used, and copper-lime liquor may be used as the liquid.  For curative baths, powdered sulphur and/or alumina may be used. British Specification 263,812, [Class 47 (ii)], and U.S.A. Specification 1,971,997 are referred to.  The Specification as open to inspection under Sect. 91 refers also to the use of foam as a carrier for solids which are to react with gases for the purpose of absorption or of separating fluid or solid constituents, and states that gases for reaction, such as cyanogen or oxygen, may be employed in making the foam.  Gases may be purified by means of a foam containing lime or calcium bicarbonate. Powdered solids may be added to foam produced chemically by the reaction of aluminium sulphate or sodium bisulphate with sodium potassium bicarbonate or carbonate.  The gas for foam production may be derived from the reaction of carbides or hydrides with water. This subject-matter does not appear in the Specification as accepted.ALSO:A lasting foam is produced by dissolving a foaming agent in a mobile liquid such as water, adding solid particles, of more than colloidal dimensions, which do not react with or dissolve in the liquid, and then dispersing a gas in the liquid so as to form the foam and disperse the solid particles in the foam.

July 24, 1931, No. 21242. Convention date, April 22. [Class 40 (v).] The frequency of a valve oscillator is kept constant, despite changes in anode voltage, by providing an auxiliary anode and applying to it a voltage proportional to that of the main anode, whereby any frequency change due to alteration of anode voltage is counterbalanced by a frequency change of equal amount but of opposite sense due to alteration of the auxiliary anode voltage. In the example shown, the tuned circuit 5 is kept in oscillation by connecting its opposite sides to the grid 2 and the anode 3, the intermediate plate of the double condenser 6 being connected to the cathode. The voltages of the anode 3 and the auxiliary anode 4 are derived from tappings on potentiometer 13 through resistances 14, 15. The auxiliary anode is connected to the control grid 2 by a variable condenser 10. The tappings 18, 19 are adjusted by experiment to positions in which an alteration of the supply voltage 12 does not affect the frequency.
