Title: Manufacture of new dyestuffs
IPC: C07D513/04
Filed: 1920-08-27
Abstract: Sulphuretted dyes, which are probably thiazines, are obtained by sulphurizing b -oxynaphthoquinonearylimides (O : OH : NR = 1 : 2 : 4), or substitution products thereof; suitable sulphurizing agents are sulphur, alone or in presence of catalysts, solvents, or diluents, disulphurdichloride, sulphur sesquioxide, or, when the aryl residue does not contain a nitro group, alkali polysulphides, preferably in alcoholic solution at temperatures not exceeding 150 DEG  C.; dyestuffs having a primary, secondary, or tertiary amino group in the p-position to the nitrogen of the thiazine ring are excluded.  The resulting products, if they contain sulphonic or carboxylic acid groups, are acid mordant dyes, or if they are free from such groups are vat dyes; the vat dyeings may be aftertreated with metal salts, preferably chromium salts, giving fast green to black shades.  According to examples:-(1) the condensation product from p-chloraniline and 1 : 2 - naphthoquinone - 4 - sulphonic acid is heated with sulphur, naphthalene, and sulphur iodide or iodine, and the product is worked up by removing the naphthalene by solvent naphtha and free sulphur by sodium sulphide solution, then dissolving the dye in concentrated sulphuric acid, pouring on ice, filtering, and washing; the paste gives a yellow hydrosulphite vat dyeing wool violet-black shades which turn to claret-red on treatment with acid, and bluish-green on treatment with chromium salts in acid solution; similar dyes are obtained by the above treatment from the condensation products of 1 : 2 - naphthoquinone - 4 - sulphonic acid with aniline, o-, m-, or p-toluidine, p-anisidine, or p-phenetidine; (2) the condensation product from 1 : 2 - naphthoquinone - 4 - sulphonic acid and p-anisidine is treated at ordinary temperature with disulphurdichloride and acetic acid; the product dyes wool in a vat violet shades becoming green on after-treatment with sodium bichromate in an acid bath; similar products are obtained by the action of disulphurdichloride on the condensation products of 1 : 2 - naphthoquinone - 4 - sulphonic acid with m- or p-toluidine; (3) the condensation product from p-toluidine and 1 : 2 - naphthoquinone - 4 - sulphonic acid is treated with a solution of sulphur in fuming sulphuric acid; the product is a sulphonic acid dyeing wool from an acid bath green shades with chrome mordants; similar green to greenish-black acid mordant dyes are obtained from the condensation products of aminosalicylic acid or aminocresotinic acid with 1 : 2 - naphthoquinone - 4 - sulphonic acid by treatment with disulphurdichloride or sulphur sesquioxide, and a black acid mordant dye by treating with sulphur sesquioxide the condensation product from p-nitraniline and 1 : 2 - naphthoquinone - 4 : 6 - disulphonic acid; (4) the condensation product from amino-N-ethylcarbazole and 1 :2 - naphthoquinone - 4 - sulphonic acid is boiled with alcoholic sodium polysulphide; the product gives a yellow hydrosulphite vat dyeing wool or cotton green shades which may be afterchromed.

Patent GB-251244-A (GB)
Abstract: 251,244. Lederer, A. April 24, 1925, [Convention date]. Carbon ; sulphur.-In the production of carbon by heating carbon disulphide, part of the vessel in which the decomposition takes place is heated to the decomposition temperature, and another part is cooled to a temperature below this but above the condensation temperature of the compound, so that carbon is deposited in the hottest regions and other decomposition products pass to regions at lower temperature. The decomposition products in the form of vapour may be separated by blowing an inert gas in from one side of the vessel so as to drive out the sulphur vapour &c. through an outlet at the other side, or the vapours may be exhausted by a pump. An apparatus for carrying out the process may consist of a tube of porcelain, quartz, or other refractory material containing an axialiy-arranged carbon heating unit or electrode. The wall of the tube is cooled, and if the cooling is not sufficient to cause deposition of the sulphur, the sulphur vapour may be expelled from the tube by causing a drop of pressure within the tube. The carbon heating unit is heated by an electric current passed through it or by electromagnetic induction; the carbon is deposited on this heating unit, and may readily be removed. The wall of the tube may be coated with carbon, platinum, &c. to prevent reaction with the material of the vessel. Alternatively the vessel mav be a tube heated externally at one part and cooled at another. The tube either consists of, or is coated with, a material such as platinum or carbon which does not react with the products of decomposition. According to the Specification, as open to inspection under Sect. 91 (3) (a), the invention is not limited to the decomposition of carbon disulphide, but is applicable for obtaining pure carbon by heating other carbon compounds. This subject-matter does not appear in the Specification as accepted.

Abstract: 536,527. Recording-apparatus. COOL, H. R. Sept. 7, 1939, No. 25291. Convention date, Sept. 9, 1938. [Classes 106 (iii) and 106 (iv)] An instrument for use on motor vehicles comprises a uniformly driven chart carrier, and two recording styluses one of which is actuated by pendulum means responsive to the oscillations of the vehicle when in motion and the other is actuated by means operated when the speed of the vehicle exceeds a predetermined value. As shown in Figs. 1 to 3 the instrument comprises a hinged casing 10, 11 with a record disc or chart 20 driven by a clock mechanism 23. The part of the chart upon which the record is to be made is supported by a spring controlled platen 25. The primary record, showing when the vehicle is in motion, is made by a stylus 30 mounted on a pendulum lever 32. The stylus is formed with a metal point to scratch a waxed surface on the chart. An auxiliary stylus 40 for the.excess speed record is mounted on an arm 41 on a pivoted U-shaped member 42. This member co-operates with a stylus operating lever 50 on a pivoted U-shaped member 51 by means of a yielding connection comprising a leaf spring 52. A coiled spring 65 normally holds the stylus free of the chart and a finger 60, 61, prevents excessive movement of the stylus. The lever 50 is operated by the armature 73 of an electromagnet connected in circuit with the ignition system and including contacts that are opened or closed when the speed reaches a predetermined amount. Thus the record may be made after the engine has been started and up to the predetermined speed or it may be made only after the speed has been exceeded.
