Title: Continuous bleaching of textiles
IPC: D06L4/26
Filed: 1957-09-12
Abstract: Textile material is bleached by impregnating it in a bath of inactive alkaline or neutral alkali chlorite, i.e. an alkali or alkaline-earth metal chlorite or ammonium chlorite, containing a potentially acid salt, i.e. a salt which, when dissolved in the alkaline or neutral chlorite bleaching solution, renders it acid on heating, removing the material from the bath, removing excess solution and then heating the material so that the solution remaining in it is acidified and activated by the decomposition of the salt therein.  Preferred potentially acid salts are those which at temperatures up to 50 DEG C. do not yield acid solutions but at temperatures of at least 60 DEG C. decompose and become strongly acid.  Suitable potentially acid salts are salts of a strong acid and a volatile base, e.g. ammonium chloride, ammonium nitrate, ammonium sulphate, ammonium phosphate, ammonium tartrate and ammonium oxalate, of a strong acid and a weak base, e.g. magnesium chloride, calcium chloride, calcium sulphate, magnesium sulphate, magnesium phosphate, calcium phosphate, magnesium nitrate and calcium nitrate, and of a strong acid and an organic base, e.g. triethanolamine hydrochloride, diethanolamine hydrochloride, triethylamine hydrochloride, diethylamine hydrochloride and ethylene diamine hydrochloride.  The bleaching solution may also contain a wetting agent, a number of which are specified.  The material may be heated by blowing in steam. Specified fibres are cotton, viscose and cuprammonium rayon staple fibres, linen, hemp and other bast fibres, cellulose di- and triacetates, nylon, "Dacron" (Registered Trade Mark) and "Orlon" (Registered Trade Mark).

Abstract: 827,689. Steam boiler steam and water drums. BABCOCK & WILCOX CO. Sept. 17, 1957 [Sept. 21, 1956], No. 29269/57. Class 123(2) In a marine boiler comprising a furnace 11 lined with radiantly-heated steam generating tubes 16B...16D and fired by burners 12, the hot gases flow from the furnace through a screen of water tubes 16A into a pass 13 locating successively a superheater 24, a convection-heated bank 17 of steam generating tubes and a bank 25 of downcomer tubes. All the tubes extend directly or via headers between a water drum 15 and a steam and water drum 14. The drum 14 is provided internally with partitions 26, 27. The low density steamwater mixture from the highly-heated tubes 16A...16D discharges into a compartment 29 between the partition 26 and the drum and flows therefrom against a baffle 40 which deflects it downwardly into the steam space of the drum. The lower velocity, higher density mixture from the tubes 17 discharges into a compartment 30 between the partitions 26, 27 and flows therefrom against a baffle 41 which deflects it horizontally into the steam space. Gravity separation of the mixtures occurs in the steam space, the separated steam discharging from the drum through an outlet pipe 33 whilst the water collects in the water space 28 of the drum. The discharge of the different quality steam-water mixtures into separate compartments and their separation above the water level in the drum improves the steam dryness and avoids entrainment of steam in the water entering the downcomers 25 thus improving the circulation head of the boiler.
