Title: Improved process for fractionating highly unsaturated fatty acids from less unsaturated and saturated fatty acids
IPC: C11C1/00
Filed: 1952-09-24
Abstract: Mixed fatty acids or their glycerides, particularly of the semi-drying oil class, are separated according to their unsaturation by treating the sodium soaps thereof in suitable particle size with a water-miscible organic solvent consisting of an aliphatic monohydric alcohol or water-containing aliphatic ketone in which the soaps of the saturated fatty acids and those with one double bond are insoluble and the soaps of the highly unsaturated fatty acids are soluble.  After removal of the solvent from the extract, the soaps in each case may be acidified to obtain the saturated fatty acids and acids of low unsaturation on the one hand, and highly unsaturated fatty acids on the other hand.  The former may be used directly as soaps, acidification being then unnecessary; the latter, after acidification, may be esterified with glycerine or pentaerythritol to obtain drying oils.  The oils specified to be treated comprise soybean oil, liver oils, sardine, herring and other marine oils.  The solvents specified comprise methanol, ethanol, isopropanol, acetone and methyl ethyl ketone.  The extraction is preferably a continuous counter current extraction and may be carried out in steps, by which the soaps of the highly unsaturated fatty acids are extracted first and then the soaps of the fatty acids of lower unsaturation are extracted, leaving the saturated acids and the acids of lowest unsaturation undissolved.
Patent GB-604512-A (GB)
Title: Improvements in or relating to the production of coated sheet material
IPC: D06M15/39
Filed: 1944-12-01
Abstract: A coating composition comprising as main ingredient a cellulose ester or ether or thermoplastic synthetic resin and also a small proportion of a salt formed from an aliphatic monocarboxylic acid of 14-18 carbon atoms and a dialkylamine of not more than 10 carbon atoms, is calendered on to fabric or other sheet material. The salt may be dibutyl ammonium oleate.  The plastic material may be cellulose acetate, ethyl cellulose; polyvinyl formal, acetal, or butyral; a polyamide, polyester amide, polyvinyl acetate or copolymers of vinyl chloride with vinyl acetate, diethyl fumarate or diethyl maleate.  In an example, the composition comprises a polyamide, diphenylol octadecane, dibutyl phthalyl butyl glycollate, dibutyl ammonium oleate, and soft carbon black.  The polyamide is formed from hexamethylene diammonium adipate and sebacate, and caprolactam.  In another example, an alkoxymethyl polyamide is used.  Another composition comprises polyvinyl acetal, dicapryl phthalate, dibutyl ammonium oleate, a urea - formaldehyde - n - butyl alcohol condensation product, clay, whiting, and pigment.  Other compositions comprise vinyl chloridevinyl acetate copolymer, butyl phthalyl butyl glycollate, barytes, dibutyl ammonium oleate, and pigment; cellulose acetate, phthalic diester of monomethyl ether of ethylene glycol, pigment and dibutyl ammonium oleate; ethyl cellulose, halogenated methyl abietate, dibutyl "cellosolve" sebacate (Registered Trade Mark), carbon black, and dibutyl ammonium oleate.  The proportion of dialkylamine salt may be 0.5 to 5 per cent of the total weight of the composition.  The presence of the salt in the composition removes the tendency of the composition to stick to metal surfaces during its preparation for calendering on to fabric. Polyester amides from combinations of dibasic acids, diamines, glycols, hydroxy acids, amino acids, and amino alcohols, and polyester amides which have been reacted with di-isocyanates, may be used.  Such products may be rendered insoluble and infusible after calendering, by treatment with formaldehyde.  Specifications 483,399, 540,134, 540,135, 553,733, 557,544, 561,108 and 573,482 are referred to.

Title: Ion exchange processes
IPC: B01J47/10
Filed: 1955-08-22
Abstract: <PICT:0775529/III/1> A process for the recovery of a selected ion from a pregnant solution by ion exchange comprises contacting the solution with an exchange-ion-bearing ionexchange-material, eluting the contacted material with an eluting ion-bearing solution to displace the adsorbed selected ion, and contacting the eluted material with an exchange ion bearing solution to displace the eluting ion into a recovered solution.  As applied to a uranium recovery process, a solution containing 1gm/litre of uranium flows upwards in a column 1 meeting a down flow of a quaternary ammonium strong base ion exchange resin and the resin and adsorbed uranium are fed intermittently to the top of a washing chamber 2 in which some slimes and excess uranium bearing solution are removed.  In column 3, the washed resin and adsorbed uranium meet an upward flow of a nitrate solution, and the nitrate ion i.e. the eluting ion is taken up by the resin which with its double charge of uranum and nitrate ions is fed to the top of column 4.  Here the uranium separates out and is delivered through an outlet 20 for normal recovery in oxide form, the residual solution being fed back to the base of the column. The resin carries the valuable nitrate ions to a column 5 where they are freed by upflowing sulphuric acid and fed back to column 3 to react with a further quantity of uranium solution.  In column 6 resin and adsorbed sulphate ion are rinsed preferably with dilute sulphuric acid, any residual nitrate being returned via the column 5.  A bisulphate ion may replace the sulphate ion.  From column 6, the resin may pass through a regenerating circuit 32 and be fed to the column 1.  The process may be used in recovering a thiocyanate ion from water.

Aug. 28, 1931, Nos. 24256/31 and 4850/32. [Classes 38 (ii) and 38 (iv).] In apparatus for supplying direct current to a secondary battery B, or to a load L in parallel with the battery, comprising a transformer TR and a rectifying device, the primary winding of the transformer being connected to the alternating current circuit through a choke or chokes, the impedance of which is varied by a magnetizing winding or windings carrying the direct current output or a part thereof, regulating means are associated with the choke or chokes and with the magnetizing windings for the purpose of varying the output characteristics of the arrangement for imposing higher and lower voltage limits at which heavy current is supplied. The arrangement is such that a heavy charging current is supplied when the battery voltage falls below the lower limit, and continues to flow until the battery voltage reaches the higher limit, after which the charging current either falls to zero or continues at a low value, so that a trickle charge still flows to the battery. In the arrangement shown, two separate chokes CH1, CH2 are provided, and the magnetizing windings MC1, MC2 are oppositely connected, so that any alternating currents induced in them cancel out. The same effect may be obtained by providing a single choke with an extra limb, not traversed by alternating flux, on which the magnetizing winding is placed. The magnetizing windings are shunted by a variable resistance R2, and the chokes by a condenser C1 and variable resistance R1. In a modified arrangement, a dip in the output characteristic is obtained by providing a further winding on each choke, these windings, shown in broken lines, being connected, in series with a regulating resistance R3, across the leads on the direct-current side of the rectifier and acting in opposition to the main magnetizing windings. The rectifying device may comprise a bridge arrangement of copper oxide rectifiers a .. d. The windings of the chokes and the magnetizing windings may be tapped to secure further regulation. The effects obtained by the various methods of regulation are described with the aid of output characteristic curves.
