Title: Improvements in and relating to the production of spongy products of rubber and rubber-like material
IPC: C08L21/00
Filed: 1937-02-22
Abstract: In the production of spongy articles of rubber or artificial rubber by frothing aqueous dispersions thereof and subsequently setting the froth in a mould, the formation of a surface skin is eliminated at least in selected places by applying to the corresponding parts of the mould surface a substance capable of reducing the surface tension of the dispersion and preferably having a stabilizing effect thereon. The surface tension reducing substance, e.g. sulphonated lorol, may be applied in the form of an aqueous solution.  The mould surface is preferably non-porous, e.g. aluminium but it may be porous, e.g. wooden.  The dispersion may be frothed by the processes described in Specifications 455,138 and 489,031.  In order to prevent the coagulated gel from collapsing owing to its lack of adhesion at the mould surface where skin formation is suppressed and also to facilitate removal of the uncured articles from the mould an insertion of a very open material, e.g. fishing net or strands of thread, may be provided transversing the moulded article.  Articles specified are toilet sponges, filters, and articles of upholstery. The Provisional Specification describes the production of spongy articles having a smooth surface skin by setting the froth in a mould having a porous surface such as plywood, cardboard, plaster of Paris, fabric or earthenware, a thicker skin being produced if the surfaces are coated with a coagulant or with a dispersion of rubber, and states that the articles are more easily removed from the mould if the surface thereof is treated with an alcohol of high molecular-weight or a soap.

Patent GB-408691-A (GB)
Title: Improvements in the manufacture and production of hydrocarbons rich in carbon from those poorer in carbon
IPC: C07C2/00
Filed: 1932-10-12
Abstract: In the conversion of normally gaseous hydrocarbons into hydrocarbons of higher carbon content, particularly into acetylene, the initial hydrocarbons are first heated sufficiently to convert them in part into normally liquid, particularly aromatic, hydrocarbons; the latter are then separated, without removing any normally gaseous olefines present, and the residual gases are subjected to partial combustion with free oxygen at a temperature above 1000 DEG  C.  Suitable initial hydrocarbons are methane, ethane, propane, butane, ethylene, propylene and butylene, and gases containing them such as natural gas, coke oven gas, cracking gases, oil-distillation gases, and waste gases from destructive hydrogenation processes.  The temperature to which the gaseous hydrocarbon must be heated for the production of normally liquid hydrocarbons varies with the hydrocarbon and the pressure used; thus, for methane at atmospheric pressure a temperature of 900--1000 DEG  C. is required, while for propylene or butylene at 5--300 atm. pressure a temperature of 250--600 DEG  C. is sufficient. The separation of the normally liquid hydrocarbons may be effected by washing or absorption.  The partial combustion of the residual gases is preferably effected with an inverted flame or by surface combustion.  In the example, a gas containing methane 8, ethane 14.2, propane 51.9 and butane 11.9 per cent is passed at 850 DEG  C. through a pipe of V2A steel coated with molybdenum to produce a gas containing ethylene 34.4, hydrogen 23.6, and paraffin hydrocarbons 39 per cent, and containing liquid hydrocarbons in the form of vapour or mist; the liquid hydrocarbons are separated by cooling and electrofiltration, and the residual gases are heated to 700 DEG  C. and then subjected at 1300--1400 DEG  C. to partial combustion with preheated oxygen, a gas containing acetylene 10.2, ethylene 15.4, methane 28.9 and hydrogen 28.2 per cent being obtained; the heat produced by the partial combustion may be used in the first heating stage.
Patent GB-417379-A (GB)
Title: Improvements in the removal of weak gaseous acids from gases
Filed: 1933-02-27
Abstract: Weak gaseous acids and readily volatile liquids in the vaporous phase are simultaneously removed from gases containing them by washing the gases with true solutions, or colloidal solutions or emulsions or suspensions of difficulty volatile strong organic bases, or of salts of strong bases with weak acids, in organic solvents preferably of high boiling point.  The weak gaseous acids referred to are hydrogen sulphide, carbon dioxide and cyanogen compounds such as hydrogen cyanide.  The readily volatile liquids referred to are benzene, benzine, carbon disulphide alcohol, ether or acetone.  Suitable organic solvents are mineral oils, tar oils, ordinary or low temperature tars, high boiling oils obtained in the destructive hydrogenation of coal &c. and alcohols of high boiling point, preferably not below 160 DEG  C.  Suitable bases or basic compounds are alkylamines such as dibutylamine, dodecylamine, ethylene diamine or the amine mixture obtainable by the catalytic reduction of the amides of coconut fatty acids; alkylolamines such as diethanolamine, triethanolamine or butanolamine; arylamines such as phenylenediamine or methylmetaphenyldiamine; alkylalkylolamines such as methylethanolamine, ethyldiethanolamine or butylmonoethanolamine; quinoline and its homologues or crude quinoline bases; pyridines such as pyridine, crude pyridine bases or piperidine or its homologues; quaternary ammonium bases such as tetrabutyl-ammonium hydroxide, or basic salts of strong inorganic or organic bases with weak acids, such as piperidine borate, tetramethylammonium borate, sodium phosphates, the sodium salt of alanine, sodium stearate, or alkali metal salts of amino- or nitro-phenols or amino- or nitro-naphthols or of boric acid, or salts of phenols.  Aniline is too weakly basic to be suitable. The gases may be washed at room temperature and atmospheric, increased or reduced pressure, the absorbed constituents being expelled by heating.  Carbon dioxide is not so readily absorbed by the solutions &c. so that it is possible to remove from gases containing, in addition to readily volatile liquids, small amounts of hydrogen sulphide with large amounts of carbon dioxide, a comparatively large proportion of only the hydrogen sulphide.  In the regeneration of the solvents by heating e.g. by direct contact with steam, the liquids of low boiling point are separated in the liquid state by condensation while the gases are recovered as such.  The weak gaseous acids dissolved in the condensed liquids may be expelled by heating.  The weak gaseous acids may be freed from the volatile liquids by washing with oil.  Examples are given which describe the treatment of coal distillation gas and coke oven gas.  The Provisional Specification describes also butyldiethanolamine and the alkali metal salts of aliphatic or aromatic carboxylic acids as being suitable basic compounds. Specifications 341,584, 391,780, and 391,786 are referred to.
