Patent GB-1004607-A (GB)
Title: Cellular masses and their production
IPC: C08J9/06
Filed: 1962-05-17
Abstract: In a process for the production of cellular masses of polymerizable resins by evolution of gas (within the mass of polymerizable resin) by the reaction between a salt and an acid an anhydrous liquid mixture is made up from at least a resin, salt and the anhydride or an acid and water is added to the mixture in the form of an aqueous dispersion of a thermoplastic resin.  A polymerization catalyst may also be a component of the anhydrous dispersion.  Specified resins are unsaturated polyesters, and acrylic, urea - formaldehyde, melamine and phenolic resins. Carbonates, bicarbonates, nitrates and nitrates may be used as salts.  Examples of anhydrides are maleic, phthalic, fumaric and pyromuric anhydrides.  By varying the water content of the aqueous dispersion it is possible to alter the speed of the reaction. The suspension may be an aqueous emulsion of styrene-butadiene or vinylidene resin or of vinyl or acrylic resins. The viscosity of the reaction mixture may be altered by adding aluminium naphthenate or heptanoate, complex silicates, ethyl or benzyl celluloses, vinyl or acrylic resins or cellulose acetobutyrate which make the mixture thixotropic.  Specified fillers are kaolin, kieselguhr, lycopodium powder, wood flour, cork powder and fibres. The products may be open or closed celled.  In an example, there are separately prepared mixtures of (A) rigid polyester from maleic anhydride, phthalic anhydride and diethylene glycol, flexible polyester resin from maleic anhydride, phthalic anhydride, succinic acid, sebacic acid, ethylene glycol and triethylene glycol (each resin being dissolved in styrene), a vinyl resin, maleic anhydride and calcium carbonate; (B) paste of benzoyl peroxide in tricresyl phosphate, dissolved in a polyester resin; (C) water, glycerine, styrenebutadiene resin emulsion and dimethylaniline. Mixtures (A) (at 55 DEG  C.) is mixed with (B) and then (C) (at 55 DEG  C.) is stirred in.  The mixture is poured into a mould and when the reaction has taken place the moulding is heated at 80 DEG  C. to remove water and styrene.
Patent GB-660130-A (GB)
Title: Improvements in or relating to anion exchange resins
IPC: B01J41/12
Filed: 1948-07-15
Abstract: In making anion-exchange resins, an irreversible gel is formed by the reaction of guanidine, biguanide or guanyl urea (in the form of free bases or their salts) with formaldehyde or paraformaldehyde and a ketone that contains at least two reactive hydrogen atoms and that reacts with formaldehyde to form methylol compounds, the reaction being carried out with or without preliminary condensation of the ketone with some of the aldehyde before any reaction with the guanidine &c. takes place and the reaction mixture being maintained alkaline throughout the reaction.  Thus the reaction may be effected either by mixing all the ingredients and heating the mixture until a gel forms or by preliminary condensation of the ketone with some of the formaldehyde and thereafter effecting further condensation by adding the guanidine &c. with the remainder of the formaldehyde. Ketones specified are: acetone, methyl-ethyl ketone, methyl n-propyl ketone and cyclohexanone.  When acetone is used, the upper limit of the guanidine &c. is 1.5 mols. per mol of acetone, and the amount of formaldehyde is from 3 to 6 mols. per mol. of acetone.  The reaction is maintained alkaline by an alkali such as caustic soda preferably in amount between 0.1 and 0.5 mol. per mol. of ketone, which is added preferably in two portions, one before and one after the preliminary condensation.  The gels produced are dried, e.g. between 70 DEG  and 160 DEG  C. and then granulated, preparation for use or regeneration consisting in treatment with caustic alkali or alkali metal carbonate. Examples are given.  Specification 572,836 is referred to.ALSO:An anion-exchange resin, formed as an irreversible gel by reacting guanidine, biguanide or guanyl urea with formaldehyde or paraformaldehyde and a ketone (see Group IVa), is used in the treatment of water or other liquid.

Patent GB-348931-A (GB)
IPC: D01F2/28
Filed: 1930-06-23
Abstract: The solutions obtained by esterifying cellulose in liquid sulphur dioxide, as described in Specification 301,036, [Class 2 (ii), Cellulose &c.], are worked up into artificial fibres or films by dry or wet spinning or extrusion processes, without first isolating the cellulose ester.  Residual catalyst that may be present in the solutions may be removed by neutralization and washing, before or after the solutions are worked up.  In one example, a solution obtained by acetylating cotton linters in liquid sulphur dioxide in the presence of hydrochloric and sulphuric acids, is treated with sufficient sodium carbonate solution to neutralize the acids present, then freed from salts and water by freezing, filtered, and spun into a dry-spinning chamber, suitably without heating.  In another example, the same solution, after filtering but without first neutralizing and removing the acids, is sprayed into water or a salt solution, and the threads are wound, washed and dried.

Patent GB-720064-A (GB)
Title: Process for the preparation of benzene and benzene homologues
IPC: C07C5/367
Filed: 1952-07-29
Abstract: Benzene and its homologues are prepared by subjecting C6 cycloalkanes viz. methyl cyclopentane, cyclohexane and mixtures thereof, to dehydrogenation in the vapour phase at an elevated temperature in the presence of a gas containing hydrogen and a platinum catalyst under pressure to form benzene, separately subjecting cycloalkanes having more than 6 carbon atoms to dehydrogenation in the vapour phase at an elevated temperature in the presence of a platinum catalyst and a gas containing hydrogen to form benzene homologues, the gas containing hydrogen being under such a pressure that the gas separated from the hydrocarbon products after this dehydrogenation is under a pressure higher than that employed in the dehydrogenation of the C6 cycloalkanes and using this separated gas, wholly or in part, in the dehydrogenation of the C6 cycloalkanes.  The C6 cycloalkanes may be contained in a hydrocarbon fraction having a boiling range closely approximating to their boiling points. Similarly, the higher cycloalkanes may be a fraction from the same or different source. The C6 hydrocarbons are preferably treated at 450-525 DEG  C., under 10-15 atmospheres hydrogen pressure and the higher hydrocarbons at similar temperatures under 20-50 atmospheres.  The catalyst is preferably used on an acidic carrier, e.g. alumina-silica or alumina treated with a hydrohalic acid or otherwise containing halogen.  The hydrocarbons are usually fed at the rate of 1-10 liquid volumes per volume of catalyst per hour and the hydrogen is used in molar amounts of 2-10 times that of the hydrocarbon.  In a process illustrated by a flow sheet (not shown) a petroleum fraction rich in C6-8 cycloalkanes is separated into C6 and C7-8 fractions. The C6 fraction is passed with hydrogen through a series of reactors containing the catalyst under the specified conditions, the mixture being heated prior to entering each reactor and the final products are separated into a benzene-rich fraction and a gas containing hydrogen, part of which is recycled.  The C7-8 is likewise treated with hydrogen in a similar series of reactors but at a higher pressure and the products are separated into a toluenexylene fraction and a gas containing hydrogen, part of which is recycled and the remainder fed into the stream of C6 hydrocarbons treated in the lower pressure hydrogenation.  If desired, the C7-8 fraction may be separated into C7 and C8 fractions and each separately dehydrogenated as above, the C8 fraction being treated under a still higher pressure and the gas separated from the xylene product being used in the dehydrogenation of the C7 fraction.

Abstract: 425,572. Valve amplifying circuits. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. July 2, 1934, No. 19492. Convention date, July 1, 1933. [Class 40 (v)] In high-frequency amplifier circuits comprising a single valve feeding a push-pull pair, the anode-cathode capacity of the first valve and the inductance between the anode and the mid-point of the output circuit are balanced by an impedance network between the cathode and the cathode side of the output circuit. The anode-cathode capacity of the valve 1 is balanced about the mid-point of the output inductance 4 by a condenser 12. The inductance of the connections between the cathode and the mid-point of 4 and the anode to the inductance 4 are represented by the lumped inductance L and this is balanced by inductances 13, 14. Balance is thus ensured for all working frequencies and the amplifier is thereby stabilized and parasitic oscillations are prevented.
