Title: Process for the Separation of Mixtures of Hydrocarbons having Different Degrees of Saturation
Inventor: GOLDUP ALAN
IPC: C07C7/152
Filed: 1966-04-27
Abstract: 1,177,343. Separating hydrocarbons. BRITISH PETROLEUM CO. Ltd. 25 April, 1967 [27 April, 1966], No. 18388/66. Heading C5E. One or more components of a hydrocarbon mixture comprising substantially all cyclic or substantially all non-cyclic components having different degrees of saturation is preferentially sorbed by contact in the liquid or vapour phase with a compound having the basic nuclear structure: and which forms an inclusion complex more readily with one or more components of the mixture than with the others. Suitable compounds are tris - (o - phenylenedioxy) cyclotriphosphazene, o - phenylenediamino cyclotriphosphazene and 2,3 - naphthyldioxy cyclotriphosphazene. These may be used in the free state, or on a support, suitable supports being ground firebrick, diatomaceous earth, silica gel, alumina or porous glass, the support preferably being silanized. The feed may be diluted by an inert gas or liquid, and the subsequent desorption of the sorbed components may be effected by displacement with another sorbate, by elution with an inert gas or liquid, by reducing the ambient pressure, or by raising the temperature. A purging stage may be interposed between the sorption and desorption steps. Typical feeds are n-hexane/hexene-1, n-heptane/ heptene-1 and cyclohexane/benzene mixtures, the first named component being preferentially sorbed in each case.

Abstract: 1,009,568. Valves. SHELL RESEARCH Ltd. May 9, 1963, No. 18394/63. Heading F2V. [Also in Division A4] A control valve for use in a liquid supply system, e.g. for aircraft refuelling (see Division A4), is actuated to reduce liquid flow by the fluid pressure at a selected point acting in conjunction with an accumulator as the pressure reaches a pre-determined value. Fluid pressure from a point 25 in the fluid supply pipe is built up in accumulator 23 from a sense line 22 through a restricted-return valve 24 and fed to the liquid space 37 beneath a diaphragm 38 which is loaded by an air space 39 to actuate closure member 29 to obturate valve inlet 27 from the outlet 28. The air space 39 may be charged with air to the required pressure via a non- return valve 42 and a pressure gauge may be connected at 41. A restricted interconnection 145 between the valve air space 39 and the air space 141 of the accumulator 23 may be employed as a " fail safe " arrangement in the event of leakage from the accumulator which would otherwise render it inoperative.

Title: Process of deflocculating solids
IPC: B01J13/00
Filed: 1926-07-23
Abstract: 259,889. Acheson, G. W. March 8, 1926, [Convention date]. Colloidal sols.-Solid bodies, such as graphite, carbon black, clay, pigments, lead arsenate, sulphur &c., are brought into the colloidal state by deflocculating and reflocculating them by attrition with an organic agent, such as tannin, cutch, or extracts from cereals or starchy bodies, and peptizing the reflocculated aggregates, preferably by means of an infusion of a grass such as hay or straw, though other suitable vegetable infusions may be used, or inorganic peptizing agents such as sodium silicate. For example, graphite in the form of a heavy paste is treated in a mill with 6 per cent of tannin, to which a small amount of ammonia has been added, until all the tannin has been absorbed. The operation is repeated, with further additions of tannin, until most or all of the deflocculated graphite is reflocculated. In the case of electric furnace graphite, for instance, 80 per cent of the charge was deflocculated and reflocculated after a total addition of tannin equal to 18 per cent of the weight of dry graphite. The reflocculated aggregates are then treated in the same or a second mill with the peptizing agent.

Patent GB-587515-A (GB)
Title: Improvements in or relating to cellulose ester coating compositions
IPC: C09D101/14
Filed: 1942-12-30
Abstract: A coating composition comprises cellulose aceto-butyrate and an organic di-isocyanate modified polyester or polyester-amide of the kind described in Specification 553,733, i.e. a high molecular weight polymer obtained by heating an organic di-isocyanate with a low molecular weight linear polymer produced from ingredients comprising a di-basic carboxylic acid or an ester-forming derivative of such an acid, at least one complementary bifunctional esterifiable compound having two alcoholic groups or one alcoholic and one amino group, and optionally one or more additional bifunctional compounds of the group comprising diamines, amino-acids, hydroxy acids, and ester or amide forming derivatives of these.  The composition may be used for coating cables particularly electric cables comprising conducting wires with insulating layers of rubber and sleeves of braided cotton, silk, or asbestos.  The composition gives coatings of good flexibility, toughness, water-proofness, oil-resistance, freedom from tackiness, and heat-resistance.  Coatings which are not thermoplastic at temperatures in the region of 150 DEG  C. are obtained. Plasticizers may be present, e.g. dibutyl phthalate, dimethyl glycol phthalate, trichlorethyl phosphate, triphenyl or tricresyl phosphate. The composition may contain an anti-oxidant, e.g. hydroquinone, phenyl-b -naphthylamine, or benzidine.  The modified polyesters or polyester-amides are soluble in some mixtures of aromatic hydrocarbons with alcohol but they may be rendered insoluble by the action of formaldehyde. Paraformaldehyde may be included in one portion of the composition and ammonium chloride or oxalate or other acid-liberating substance in another portion, the two portions being blended just before the composition is used.  In an example, an organic di-isocyanate modified polyesteramide is dissolved in a mixture of benzol and alcohol, and hydroquinone is added. Paraformaldehyde is added to one portion of the solution and ammonium chloride is added to another portion.  Each portion is then mixed with a separate solution of cellulose acetobutyrate containing tricresyl phosphate, benzol, alcohol, and acetone. The two solutions are then mixed together and a cotton braided cable is coated several times with the lacquer so formed.  After drying, the coating is allowed to age by hanging the cable at room temperature for several days.  In another example methyl ethyl ketone is used as the solvent. Specifications 580,524 and 581,134 also are referred to.
