Title: Improvements in or relating to the conditioning of anthraquinone vat dyestuffs
IPC: C09B67/28
Filed: 1948-01-13
Abstract: An anthraquinone vat dye is made into a physical form suitable for use as a pigment by admixing with aniline or a nuclear-substituted aniline in the liquid state, and thereafter separating the mixture into its component parts.  The aniline is preferably liquid at room temperature, but heat must be used otherwise.  The aniline may be separated by conversion to a watersoluble salt (e.g. hydrochloride or sulphate and washing with water, by steam distillation, or by solvent extraction.  The dyestuff may also be subjected to acid-pasting.  The amines may contain halogen, alkyl, or alkoxy substituents.  The mixing may be accompanied by grinding.  In examples: (1) N-dihydro-1 : 2 : 11 : 21-anthraquinone azine is mixed with aniline in a Baker-Perkins mixer, with and without prior acid-pasting with sulphuric acid, followed by conversion of the aniline to its hydrochloride or sulphate and washing with water; (2) the same dyestuff is ground in a ball-mill with the following amines, followed by separation of the amine hydrochloride: (a) o-toluidine, (b) m-toluidine, (c) technical mixed toluidines, (d) technical mixed xylidines, (e) m-chloraniline, (f) p-tert.-butyl-aniline, (g) 2-amino-4-chloro-toluene, (h) o-anisidine; (3) Flavanthrone is acid-pasted with sulphuric acid, mixed with aniline, and the aniline separated as hydrochloride; (4) 1.2-anthraquinone-naphthacridone is treated as under (3). Specification 503,666, [Group IV (b)], is referred to.

Abstract: 1,126,677. Knitting. KAYSER BONDOR Ltd. 9 Jan., 1967 [13 Jan., 1966], No. 1101/67. Heading D1K. A circularly knitted compressive structure, as shown in Fig. 1 comprises a sequence of courses comprising knitting at least one course of an elastomeric yarn such as spandex, followed by at least two courses of inelastic yarns such as opposite hand synthetic yarns one of which is knitted in a tuck formation in alternate wales in the first sequence followed by it being knitted in a tuck formation in the intermediate wales in the following sequence. The loops of the tuck course are drawn larger and cause the loops of the previous inelastic yarns combined with the tuck loops to rob yarn from adjoining loops such that the yarn in the latter loops is straightened out and the following course yarn caused to distort around it to form locking loops within the bight of the loops of the elastomeric yarn. Other yarn sequences can be achieved on a three, four or more feeder circular machine.

Title: Process for desulphurising enriched gas-purifying materials
IPC: C10K1/26
Filed: 1953-01-19
Abstract: Gas purifying materials are desulphurized for re-use by roasting with gases containing sulphur dioxide and not more than 21 per cent. by volume of oxygen at a temperature above the ignition temperature of sulphur and not substantially over 400 DEG C. whereby part of the sulphur is burnt to sulphur dioxide and part sublimed.  In one method gases resulting from roasting sulphide ores may be utilized after cooling to about 300 DEG -400 DEG C. by the addition of air or by indirect cooling &c.  Part of the oxygen present is used for combustion of the sulphur to produce heat to warm up the material and distil some sulphur.  An alternative method employs gases obtained by burning a hydrogen sulphide-containing gas escaping from an ammonium sulphate saturator.  Additional air or inert gases may be included as for cooling, the roasting gases desirably containing about 3-12 per cent. sulphur dioxide and enough oxygen to burn the required amount of sulphur to maintain the reaction temperature. Specification 683,480 is referred to.
