Title: Improvements in the bonding of polyamides to rubber
Inventor: CANTZLER ERIKA
IPC: C08J5/06
Filed: 1958-06-04
Abstract: An adhesive for bonding polyamides to rubber comprises a mixture of 80 to 40% (all percentages by weight) of a 10 to 20% aqueous solution of a resorcinol-formaldehyde condensate at a molar ratio of formaldehyde to resorcinol of from 1:2 to 2:1 and p  20 to 60% of a 20 to 60% aqueous dispersion of a copolymer derived from 30 to 70% butadiene, 67 to 20% styrene and 3 to 10% of a N-vinyl-imidazole (including substituted derivatives) or a N-vinylcarbazole (including substituted derivatives).  For use with a polyamide fabric, the fabric may be soaked or impregnated with the adhesive mixture, allowed to dry and then pressed on to the rubber at 150 DEG C. with a pressure of about 20 kg/cm2.  If foils of polyamides are used, they are preferably pre-treated with an aqueous solution of a resorcinol-formaldehyde condensate. Example (1) describes a conventional preparation of a butadiene-styrene-N vinylimidazole copolymer and also the preparation of a suitable resorcinol-formaldehyde condensate.  A finely meshed fabric of polyamide fibres is bonded with a mixture of these two components on to an unvulcanised natural rubber.  In another example N-vinyl-benzimidazole replaces N-vinylimidazole.

Title: Hydrogen chloride purification
IPC: C01B7/01
Filed: 1958-06-05
Abstract: <PICT:0843996/III/1> An aqueous hydrochloric acid solution is freed from volatile impurities by passing the solution into a stripping zone in which the solution is stripped of the impurities by a vapour stream of hydrogen chloride and water, derived from the distilling zone, and removing from the stripping zone hydrogen chloride contaminated with the impurities as vapour, and a solution more concentrated with respect to HCl than the initial solution.  This withdrawn solution is passed to a distilling zone which is operated at a higher pressure than the stripping zone, and is distilled, to provide an aqueous azeotropic hydrochloric acid solution as liquid effluent, and a vapour effluent of hydrogen chloride and water, part of which is passed to the stripping zone to strip the incoming solution, and the remainder is separated e.g. by condensation into anhydrous hydrogen chloride and aqueous hydrochloric acid, which may be returned to the distilling zone. The pressure in the distilling zone is preferably maintained between 1 and 3 atmospheres absolute and between 0.9 and 1.5 atmospheres absolute in the stripping zone. Preferably less than 60%, especially 15%-30% of the vapour from the distilling zone is passed to the stripping zone.  The initial contaminated solution may be that obtained in thermal chlorination of aliphatic hydrocarbons followed by washing with aqueous media.  The contaminants generally consist of chlorine and chlorocarbons, for example carbon tetrachloride, perchloroethylene, methylene chloride, methyl chloride, and chloroform.  In the Figure the initial hydrochloric acid solution 1 enters the stripping column 3, and a vapour effluent-containing the contaminants leaves at 5. The more concentrated hydrochloric acid leaves at 6 and enters the distillation zone 8, from which azeotropic hydrochloric acid leaves at 9, part of which enters reboiler 11 and is recycled to zone 8, and the remainder leaves via line 12.  Part of the vapours leaving at line 14 are passed to the stripping zone via line 15, and the remainder enter the partial condenser system 17, which consists of a first condenser operated with cooling water and a second condenser operated with refrigeration.  The liquids condensed by these condensers are recycled to zone 8 via line 18, and substantially anhydrous hydrogen chloride leaves the refrigerated condenser via line 19.

Title: Process for the production of synthetic resins
IPC: C08G8/28
Filed: 1931-06-23
Abstract: Alkali metal compounds of phenolalcohols, which include all derivatives of mono- or polyhydric, mono- or multi-nuclear phenols which contain one or more alcoholic hydroxyl groups, are condensed with partially halogenated polyhydric alcohols, which include all polyhydric aliphatic alcohols such as glycol or glycerol in which one or more hydroxyl groups are replaced by halogens but wherein at least one alcoholic hydroxyl group is not replaced or mixtures thereof, to yield resinous products soluble in water and which are probably aryloxyalkylethers.  Phenolalcohols may be dissolved in alcoholic caustic soda lye and heated with the partially halogenated polyhydric alcohol, sodium chloride be precipitated and separated by filtration and the products obtained by removing the alcohol in vacuo.  The products may be used for impregnating, insulation, varnishes and plastics.  In examples (1) a cresol-alcohol obtained by treating technical cresol with formaldehyde in the presence of alkali and liberating the alcohol by means of acid is dissolved in alcoholic caustic soda and heated with a -monochlorhydrin; sodium chloride is separated by filtration and the alcohol is removed under reduced pressure giving a product, soluble in alcohol and water, which turns gummy, hard and insoluble after heating.  (2) Diphenylolpropanetetraalcohol dissolved in alcoholic caustic soda is treated with glycolchlorhydrin to give a diphenylolpropanetetraalcoholdiethanoldiether of the formula <FORM:0381200/IV/1> The product, which may be acetylated, is converted into a hardened mass by heating.  (3) A crude diphenylolpropanetetraalcohol prepared according to example 1 of Specification 261,522, [Class 2 (iii), Dyes &c.], dissolved in alcoholic caustic soda is heated with a -dichlorhydrin.  The Specification as open to inspection under Sect. 91 (3) (a) refers generally to the use of metal compounds of phenol-alcohols; this subject-matter does not appear in the Specification as accepted.

Abstract: 1,111,264. Determining oxygen content of molten metal electrically. YAWATA IRON & STEEL CO. Ltd. May 4, 1965 [May 6, 1964], No. 18682/65. Heading G1N. The oxygen content of molten metal is measured by means of a standard electrode 4, 5, 6 (Fig. 1) used as a reference in measuring the oxygen potential and a metallic electrode 8, which project through the bottom wall of a crucible 2 and contact the melt, and are connected to a recording meter 9. The standard electrode comprises a permeable shell 4, acting as an intermediate electrolyte, (of sintered magnesia, zirconia, alumina, silica, beryllia or thoria), which may be filled with powdered material 5 of constant low oxygen potential (e. g. graphite or silicon carbide), and a conductive rod 6 (of graphite, tungsten, silicon carbide). The crucible contents may be heated by a h. f. energized induction coil 1. The electrode 8 may be of iron tungsten or nickel surrounded by refractory material. In an alternative embodiment Fig. 3 (not shown) the standard electrode is constituted by an electrocast magnesia plug (4), which is used simultaneously as the intermediate electrolyte and as the standard electrode material and has a conductive rod of platinum or nickel embedded therein which is connected to the recording meter. When used in an industrial furnace Figs. 5, 7 (not shown) there may be a number of the standard electrodes (such as the Fig. 3 embodiment) used, each electrode being disposed in the furnace bottom wall at a different depth below the surface of the furnace adjacent the melt. As the furnace wall erodes in time then succeeding electrodes are selectively switched into a measuring circuit according to which one is exposed at the said surface.
