Patent GB-813885-A (GB)
Title: Process for the oxidative polymerisation of viscous liquids
IPC: C09F7/06
Filed: 1957-06-12
Abstract: <PICT:0813885/III/1> Unsaturated oils, such as linseed, castor, safflower, tung or fish oil, are oxidatively polymerized ("blown") by a process in which a film is drawn from the surface of a pool of oil contained in a reactor by means of one or more revolving bodies which dip into the liquid, such as a drum, the film then being exposed to air or other oxygen-containing gas.  As shown, a suitable apparatus comprises a trough 1 containing heating or cooling means and a drum 3 dipping into oil contained in the trough, the drum being rotated by means of axle 4 connected to belt-driven pulley 10.  The upper part of the drum is enclosed by a hood 6 through which pass oblong nozzles 7 connected by pipes 8 to an air supply, whereby air is blown on to and over the surface of the oil film carried on the surface of the drum when the drum is rotated. As desired, the air may be heated or cooled before use.  Scraper blade 9 removes excess liquid, and another blade (not shown) may be provided to strip the treated film of oil from the drum.  If desired, two or more reactors may be used in cascade in order that different conditions may be applied during different stages of the process.  For example, the first stage may be confined to peroxidation in the absence of catalyst, while polymerization, preferably in the presence of a catalyst, is left to subsequent stages.

Title: Improvements in or relating to the manufacture of explosives
IPC: C06B21/00
Filed: 1934-06-22
Abstract: 438,218. Conveying liquid explosives. BURDEN, W. M., JACKSON, C. G., PRING, J. N., and ROTTER, G., c /o Research Department, Royal Arsenal, Woolwich, London. June 22, 1934, No. 18564. [Class 102 (ii)] To avoid risk of transmission of detonation in transferring a liquid explosive from one place to another during manufacture, the liquid explosive, for example nitroglycerine, is mixed with an inert liquid, for example water, and conveyed through a conduit having means which cause sufficient turbulence to produce or maintain an emulsion or suspension of the explosive in the inert liquid. The turbulence may be produced by a helical ridge or other sinuosities, bends, or obstructions in the conduit, or by making the conduit in the form of a flattened and twisted pipe.

Abstract: 1418769 Treating spent liquors by electrodialysis SYBRON CORP 17 April 1973 [5 May 1972] 18565/73 Heading C7B Spent acid liquor containing metal, e.g. produced in the digestion/extraction of ores or the pickling of metals with inorganic acid, is treated, eg. to recover and concentrate H 2 SO 4  or HCl from depleted pickle liquor used to remove mill scale, by passing it through a spent liquor chamber 18 of an electrodialytic apparatus comprising in sequence an end anode chamber 14 with an anode 10 e.g. of Pb therein, at least one concentrating chamber 16 separated from the adjacent anode chamber by an ion permeable (anion or cation permselective or non-selective) membrane 4, the spent liquor chamber 18 separated from the (first) concentrating chamber by an ion permeable (anion permselective or non-selective) membrane 6 which permits migration of anions e.g. sulphate or chloride, and an end cathode chamber 20 with a cathode 12 e.g. of steel therein separated from the spent liquor chamber by an anion permselective membrane 8, each chamber having an inlet 34, 46, 48, 64 and outlet 38, 40, 52, 62 so that anolyte (e.g. H 2 SO 4  or HCl), electrolyte (e.g. H 2 SO 4 , CrO 3 , HCl and/or HNO 3  or acetic, citric and/or oxalic acid), spent liquid (e.g. H 2 SO 4 -FeSO 4 , HCl- FeCl 2 , H 2 SO 4 -NiSO 4 , CrO 3  containing Cr, Fe, Al and/or Mg ions, Cr03- A12 (CrO 4 ) 3  with or without HNO 3  or H 3 PO 4 ), and catholyte (e.g. NaOH, KOH, NH 4 OH, Ca(OH)2 and/or Ba(OH)2), respectively, is subjected to electrodialysis to concentrate acid in chamber 16 and form insoluble products in chamber 18. The catholyte contains ions (e.g. OH) which form insoluble products in the spent liquor chamber 18 with the metal and preferably a sequestrant, e.g. triethanolamine, N-2- hydroxyethylenediamine, 2-(2-hydroxypropylamino)-ethylamine, diethylenetriamine, triaminotriethyleneamine, tetrakis-(2-aminoethyl)- ethylenediamine or triethylene-tetraamine, to prevent formation of insoluble compounds (e.g. ferrous /ferric hydroxide) within the matrix of membrane 8. As shown, insoluble products formed in chamber 18 are removed in device 26 and the liquor depleted of insoluble products is fed to chamber 46, the effluent therefrom being the influent anolyte stream. Preferably two concentrating chambers are interposed between the spent liquor and anode chambers Fig. 3 (not shown), the electrolyte feed stream of one being the effluent of the other. Similarly, there may be two anode chambers separated by a non-selective membrane.
