Patent GB-603280-A (GB)
Title: Improvements in the production of morpholine salts of sulphonated azo dye components
IPC: C09B69/04
Filed: 1945-12-20
Abstract: Sulphonated azo dye components (e.g. diazotizable amines, coupling components and diazoamino compounds) in which at least one sulphonic acid group is neutralized by morpholine are manufactured by reacting the sulphonated component with morpholine at a temperature sufficient to volatilize any excess morpholine. When the azo dye component contains more than one sulphonic acid group, the amount of morpholine may be so chosen as to neutralize all the sulphonic acid groups, or only part thereof, in which case the remaining sulphonic acid group or groups may be neutralized by another base, e.g. an alkali metal (sodium or potassium) or an organic amine such as an alkylamine, an arylamine or an alkylolamine.  A sulphonated diazotizable amine may be diazotized and then reacted with morpholine to neutralize the sulphonic acid group with simultaneous formation of a diazoamino compound.  In examples: (1) chromotropic acid is slurried with excess of morpholine and the mixture is then heated to 65-70 DEG  C.; (2) R-acid is ground in a ball mill with an equimolecular proportion of morpholine and the product is dried; (3) G-acid is treated as in (1); (4) chromotropic acid is slurried and heated with a solution of diisopropanolamine in morpholine to produce a mixed salt; (5) naphthionic acid is treated as in (1); (6) sodium naphthionate is diazotized and the diazo compound is stirred with excess of morpholine in the cold, followed by heating to about 70 DEG  C.; (7) 2-naphthylamine-3 : 6-disulphonic acid is treated as in (1); (8) 4 : 41-diaminostilbene-2 : 21-disulphonic acid is similarly treated. Lists are given of additional sulphonated diazotizable amines (of the benzene, diphenyl and naphthalene series) coupling components (of the naphthalene series, especially naphtholsulphonic acids, and of the pyrazolone and heterocyclic series), and stabilized diazoamino compounds and amines for use as stabilizers therein.

Title: Process for the production of high apparent density water atomized steel powders
IPC: B22F9/08
Filed: 1974-08-06
Abstract: 1475421 Making steel powder USS ENGS & CONSULTANTS Inc 6 Aug 1974 [16 Aug 1973] 34650/74 Heading B3A A method of making steel powders having high apparent densities from water atomized steel particles comprises annealing the particles at 1400-2100 F. to soften them and reduce their oxygen content to below 0À2 wt. per cent, the annealing causing the particles to sinter together, and grinding the annealed sintered particles in a disc mill to produce powder with an apparent density in excess of 3À2 gm./c.c. and a particle size generally finer than 80 mesh. The atomized particles may contain up to 0À8% C, but preferably less than 0À15% C, and the carbon content is lowered by annealing in a decarburizing atmosphere. The initial oxygen content of the particles after atomizing is about 1% and they pack to a high apparent density, i.e. in excess of 3À2 gm./c.c. After annealing, which is carried out in a reducing atmosphere, e.g. hydrogen or dissociated ammonia, the apparent density is 2À8-3À2 gm./c.c. and the particles are in the form of a sintered cake. The cake is broken into small pieces which are fed to the centre of a disc mill, the resulting particle size being determined by the mill gap and the speed of rotation of the discs.

Title: Improvements in or relating to the production of knitted fabrics
IPC: D04B1/18
Filed: 1938-11-29
Abstract: 521,958. Knitting. GUYLER, A.F., and BOALER, W. H. Nov. 29, 1938, No. 34723. [Class 74 (ii)] Relates to a two - way stretch knitted fabric with laid-in elastic thread, for bathing costumes &c. The elastic thread is laid in, in zigzags, to form hexagons and/or diamonds. The material is made on a 12-feeder circular rib machine from which all the dial needles have been removed and replaced by a fewer number of the pushers shown in Fig. 7 which are provided with butts 18... 21 and throats 43. At feeders 2, 3, 5, 6, 8, 9, 11 and 12 the dial and cylinder cams shown in Fig. 2 are used. ' Fig. 3 shows the cams used at feeder 1 there being a half thickness cam 27 in the pasage 17 which advances the long pusher butts 21. A similar cam 29 advances long needle butts 25, while the short butts 24 rise up a slope 32, Fig. 8. The cams used at feeder 4 differ only in that the cam in the passage 17 is of full thickness and so projects all pushers with long or short butts 20, 21. Fig. 5 shows the cams for feeder 7 ; there is a half thickness cam 27 in passage 16 for acting on long pusher butts 19, while the cams for feeder 10 have a full thickness cam 27 in passage 16 to act on both long and short pusher butts 18, 19. To produce the flat diamond pattern shown in Fig. 11, the long and short butt needles are arranged alternately and at the places where two elastic threads are to be caught in together a pusher with a long butt 21 is placed. This pusher passes loops of elastic threads 40, 41 over the head of the neighbouring short butt needle which is depressed by ledge 31, and against' the stems of the two long butt needles on either side, which have been raised by the slope 30. While the elastic threads are thus stretched out, the short butt needles of the vicinity pass up slope 32 and retain the elastic threads in position as shown at 63. Similarly, the threads 40, 41 are tied in at mid-points 66. The places where the elastic threads are tied in in pairs may be extended over as large a number of needles as desired.

Abstract: 1430602 Wet air oxidation NIPPON STEEL CORP 23 July 1973 [22 July 1972 (2) 22 Nov 1972] 35071/73 Heading C1C [Also in Divisions C4-C5] Removal of H 2 S, NH 3  and, where present, HCN, from gases is effected by successively contacting the gas with (i) (optional) an aqueous solution or dispersion containing sulphur and/or polysulphides at pH > 7 to absorb HCN; (ii) an aqueous solution containing a redox catalyst at pH # 7 to absorb H 2 S; and (iii) an aqueous solution containing sulphate ions to absorb NH 3  and precipitate ammonium sulphate. Before recycling, the spent liquor from (ii) is regenerated by contact with an oxygen-containing gas (e.g. air) and its pH restored by drawing off a part thereof and replacing it with water, with addition of alkali if necessary. The drawn-off liquid is optionally filtered to remove sulphur (which may be fed to stage (i)), and is fed, optionally together with liquor similarly drawn off from absorbing solution circulating in stage (i), to a wet air oxidation stage (vide infra) from the effluent of which ammonium or calcium sulphate may be recovered; alternatively the effluent is fed to stage (iii). The gas may be coke oven gas, petroleum decomposition gas, petroleum purification gas, coal decomposition gas, natural gas, or gas from organic waste treatment. The redox catalyst may be iron oxide, manganese oxide, picric acid or a derivative thereof, or a quinone, naphthoquinone or anthraquinone derivative. Wet air oxidation of the above effluent, which contains one or more of sulphur, sulphites, thiosulphates, thiocyanates and polysulphides, is effected by contacting it with an oxygencontaining gas (e.g. air or oxygen, preferably in excess) at a temperature above 150‹ C. and at a pressure (e.g. 4À7-120 atm.) greater than the saturated vapour pressure of water at the temperature used. The effluent may be initially diluted with water and pre-heated by heatexchange with the oxidized liquor. Alkali (e.g. lime, quicklime, CaCO 3 , NaOH, Na 2 CO 3 , KOH, K 2 CO 3 , NH 3 , NH 4 OH) may be added before or after the oxidation so that the pH of the oxidized sulphate-containing liquor is above 7.
