Title: Method of and apparatus for the separation of gases
IPC: B01D67/00
Filed: 1958-01-29
Abstract: Mixtures of gases of different molecular weight are separated by diffusion through a semi-permeable membrane consisting of a sheet of aluminium oxide formed by anodic oxidation of aluminium foil.  Foil of thickness 0.007 to 0.05 mm. is suitable and is preferably treated on both sides with sulphuric acid and electrolysing at 8-50 volts. Oxalic, chromic or phosphoric acid may also be used.  The aluminium is substantially completely converted to an oxide layer which may be etched with acid, washed, and dried at 520 DEG  C. to increase the pore size diameter from 200 <\>fA to about 400 <\>fA.  Any aluminium metal remaining may be removed by treatment with chlorine at 500 DEG C.  The alumina sheet is preferably supported by a close mesh wire screen or a ceramic. A series of such permeable membranes may be mounted in separation cells connected in series, whereby a gas rich in one component appears at each end of the series.  For example, U235 may be separated from U238 by treatment of the gaseous uranium hexafluoride.

Patent GB-800710-A (GB)
Title: Improvements in or relating to detergent compositions
IPC: C11D3/32
Filed: 1957-01-29
Abstract: Detergent compositions contain an organic soapless detergent and an N-tris-(hydroxymethyl) - methylamide having the general formula R.CO.NH.C(CH2OH)3 where R is a saturated alkyl radical of 9.15 carbon atoms or an unsaturated alkyl radical of 9-17 carbon atoms.  The detergent may be anionic, non-ionic, or cationic and may be, for example, a sulphated fatty alcohol, a secondary alkyl sulphate, an alkyl sulphonate, an acyl tauride, a sulphonated alkylaryl hydrocarbon, cetyl-trimethylammonium bromide, a condensation product of ethylene oxide with an alkylphenol, or mixtures of such detergents.  Anionic detergents may be present as the alkali metal, ammonium or amine salts, the latter two being preferred if the compositions are to be produced in liquid form.  The compositions may also be produced in the form of powders, flakes, granules, or tablets.  The N-tris-(hydroxymethyl)-methylamide is typically derived from caprylic, myristic, palmitic or oleic acid, or from mixtures consisting essentially of such acids, such as those obtainable from oils such as coconut or palm oil; such mixtures should be free from appreciable quantities of stearic or higher saturated acids.  The preferred compound is N-tris-(hydroxymethyl)-lauramide.  The compositions may also include sulphates, silicates, carbonates, condensed phosphates, salts of carboxymethylcellulose, colouring agents, perfumes and, in the case of liquid compositions, solvents such as water, lower alcohols or alkanolamines, and thickening agents such as polyethylene glycols.  The pH of the compositions should be greater than 7, preferably 7-10, and may be adjusted, if necessary, by the addition of a base such as potassium hydroxide. A liquid composition normally contains 23-42 per cent of detergent and 8-12 per cent of the N-tris-(hydroxymethyl)-methylamide; in the case of solid compositions this latter proportion is 0.5-15 per cent.ALSO:N-Tris(hydroxymethyl)-methylamides having the general formula R.CO.NH.C(CH2OH)3, where R is a saturated alkyl radical of 9-15 carbon atoms or an unsaturated alkyl radical of 9-17 carbon atoms, are obtained by reacting the appropriate carboxylic acid or its chloride or anhydride with tris-(hydroxymethyl)-methylamine.  The 2-alkyl-4 : 4-bis-(hydroxymethyl)-oxazoline so formed is then partially hydrolysed by alcoholic hydrochloric acid, or by boiling with water, to yield the required compound.  Specified compounds are the N-tris-(hydroxymethyl)-methylamides of caprylic, lauric, myristic, palmitic and oleic acids, and of mixtures of acids derived from coconut and palm oil, such mixtures being free from appreciable quantities of stearic or higher saturated acids.

Title: Improvements in or relating to crankcase breathers for internal combustion engines
Inventor: SPARROW ALAN WYCLIFFE
IPC: F01M13/04
Filed: 1968-01-23
Abstract: 1,255,642. Separating oil from air; centrifugal separators. PERKINS ENGINES Ltd. 6 Jan., 1969 [23 Jan., 1968], No. 3478/68. Headings BIT and B2P. [Also in Division F1] ; An I.C. engine crankcase breather includes means for separating oil from a gas in which it is suspended, means for venting the gas after the separation and a duct adapted to contain a pressure head of separated oil so that, in use, the duct allows the separated oil to return to the crankcase while preventing back flow from the duct, the means for separating the oil comprising a primary and a secondary oil separator. Oil suspended in gas rises from the crankcase through rocker box 2 and tube 4 into cap 7 in which a primary separation takes place in a first wire mesh filter 10. The initially separated oil drops through portion 8 into chamber 9. The pressure in chamber 9 remains greater than atmospheric pressure and the gas rises through a second wire mesh filter 12 where the remaining oil is separated out and falls to the bottom of chamber 9 whilst the gas is vented to atmosphere. The separated oil is returned to the crankcase through duct 13 in which a pressure head A is maintained to prevent back flow. In modifications the duct either extends into a reservoir 18 or the duct 13 is twisted to form a vertical loop. In another embodiment the crankcase gas flows through an inlet tube 28, Fig. 2, tangentially into a casing 20 so that a primary separation takes place centrifugally and the separated oil flows into a duct 22. The gas rises through a filter 27 and further separated oil is returned to duct 22 whilst the gas is vented into the inlet manifold 32 through a spring loaded valve 31. In another embodiment the breather casing has an inlet aperture and an annular flange (39), Fig. 4 (not shown) in which a closed permeable walled tube (40) forms an upwardly directed extension. Crankcase gases flow up a helical ramp (49) between the casing and the tube and are vented from the open end of the casing. Oil separated by centrifugal forces runs to the centre of the ramp and through the permeable wall into a cylindrical duct which extends within a cup reservoir (43). A hole (46) in the reservoir above its lower end allows overflow of the separated oil into the rocker box. In modifications of this embodiment the helical ramp is formed from metal, or plastics or resin-based paper or wire or glass mesh or moulded integrally with the tube. The casing may include a wire mesh filter.

Filed: 1972-01-25
Abstract: 1380303 Mixing in conduits KENICS CORP 25 Jan 1972 [25 Jan 1971] 3480/72 Heading B1C A method of producing a predetermined minimum Sauter mean diameter drop size of one fluid phase in another, immiscible, fluid, with a narrow drop size distribution and for maintaining the drop size and distribution substantially constant comprises injecting the phases into an apparatus of the type described in Specification 1,122,493 in which the elements are arranged in alternate right and left hand curvature groups, with a velocity corresponding to that Weber number which will produce drops of the predetermined minimum Saunter mean diameter. As shown in Fig. 1, material of the continuous phase is supplied by a pump 13 to a header 15 into which material of the disperse phase is injected from a tube 16. The flow velocity of the mixture is primarily dependent upon the flow of the continuous phase; the pump 13 may therefore be controlled by a regulator 17 which may be calibrated in rate of flow through the conduit 10 or in Sauter mean drop size for the dispersion involved. The fluids may include gases, liquids, or fluent solid; applications may include making emulsions and non-stable dispersions in, e.g. chemical reactions, solvent extraction, classification of liquids, and heat exchange. A preferred use is the oxidation of sodium sulphite by dispersion of oxygen-containing gas in effluent water from washing of stack gases.
