Title: Process for the preparation of ª‡-glycols and their derivatives
Inventor: AUSTERWEIL GEZA VICTOR
IPC: C07C29/10
Filed: 1949-10-17
Abstract: a -Glycols, the corresponding di- or polyglycols and alkyl ethers of a -glycols are prepared by reaction of 1 : 2-alkylene oxides with a compound of the general formula R-OH, where R is hydrogen or an alkyl radical, in the presence of an organic hydrogen-active cation-exchange material.  The reaction may be carried out under atmospheric or slightly higher pressures. Reaction with water yields the glycols, polyglycols being obtained by increasing the proportion of epoxide used.  Methyl, ethyl, butyl and so on ethers of the a -glycols result when the alcohols are employed.  In examples: (1) ethylene oxide is bubbled through water containing in suspension a finely-divided resorcinol-formal hydrogen activated cation exchanger, the temperature being maintained at 41 DEG  C. and the products comprise 90 per cent a -glycols with higher glycols; (2) ethyl alcohol and gaseous ethylene oxide are passed in counter-current flow through a hydrogen-activated cation-exchanger of sulphonated polystryrolene at a temperature maintained below 35 DEG  C. and glycol ethyl ether is recovered from the resulting alcoholic solution.  Propylene oxide is also mentioned as a reagent and sulphonated lignites and phenolformaldehyde resins are given as further examples of suitable cation-exchangers.  The Specification as open to inspection under Sect. 91, relates to the production of glycols and their derivatives by reaction of 1 : 2-alkylene oxides with compounds of the formula R-OH, where R may be hydrogen or an alkyl, aryl or aralkyl radical, in the presence of an acid catalyst insoluble in water and the glycol solutions formed and natural and artificial zeolites are mentioned.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to grinding and like processes
Inventor: POPE PETER JAMES
IPC: B24B49/16
Filed: 1964-06-27
Abstract: 1,114,415. Grinding, stropping, honing, polishing. WILKINSON SWORD Ltd. 23 June, 1965 [27 June, 1964], No. 26687/64. Heading B3D. A method of effecting an abrasive process, e.g. grinding, stropping, honing or polishing, in which an abrasive member is applied to the material being processed with a force of predetermined value includes the steps of (a) continually monitoring the presence of the material to be processed by sensing a partial vacuum maintained by the material, the partial vacuum being broken when the material is absent, and (b) applying a counterforce to the abrasive member in response to breaking of the vacuum, the value of the counterforce being greater than the predetermined value. Razor blade strip conveyed by a pegged band through a guide 16, is stropped by stropping discs 10, 10 carried by a pair of double arms 11, 11 pivoted at 12 on a part 13 mounted on a slide 14 adjustable towards and away from the guide 16 by a control knob 15. The arms 11, 11 carry counterbalance weights 20, 20. The discs 10, 10 may be driven from one or more motors mounted on the machine base and driving through a layshaft coaxial with the pivot 12 and belt or chain drives. For other operations on the strip grinding or honing wheels or polishing pads are used instead of the discs 10 10. One double arm 11, 11 is loaded by a pneumatic cylinder 22, supplied from a reservoir 23 through a regulator 24; a gauge 25 is provided. The arms are damped by an hydraulic, pneumatic or eddy-current damper 26. The other double arm is similarly but oppositely loaded. Partial vacuum may be used instead of pressure. Contact of the discs with the guide when no strip is present is prevented by a pneumatic cylinder 27 supplied from the reservoir 23 through a regulator 29. When strip is present it closes a hole 31 so that a vacuum pump 32 reduces the pressure on one side of a diaphragm valve 30 to cut off the air supply to the cylinder 27. The controlled loading and the counterforce may be produced by other means than penumatic, e.g. by dead weights, electrical means, hydraulic pressure or springs in conjunction with mechanical linkages.

Abstract: 1435127 Silylesters of sulphonyl azides; modified hydrocarbon polymers SHELL INTERNATIONALE RESEARCH MAATSOHAPPIJ BV 5 June 1973 [7 June 1972] 26735/73 Headings C3S and C3P Novel silyl esters of sulphonyl azides having the formula (N 3 SO 2 ) m -A-(COOR) n , wherein A denotes an organic group (e.g. an aliphatic or aromatic group), R denotes H or a silyl group -SiH x R<SP>1</SP> y  provided that at least one R denotes such a silyl group, m and n denote integers of from 1 to 3, R<SP>1</SP> denotes an organic group, x is 0 or 1 and y is 2 or 3, so that x + y is 3, are prepared by reacting a compound of formula (N 3 SO 2 ) m -A-(COOH) n  with a silylating agent introducing a group -SiH x R<SP>1</SP> y . The above compounds are added as modifiers to hydrocarbon polymers in relative quantities varying from 0À001 to 20% by weight and are subsequently hydrolysed in situ and the mixture then heated to between 115‹ and 250‹ C., when the azide group reacts with the polymer with the evolution of nitrogen. The silyl ester may be added to the polymer as a solution or to a solution of the polymer. Silyl ester may also be added to molten polymer or may be used to treat the surface of polymers, particularly when the latter are in the form of yarns or fabrics. Hydrolysis may be effected by means of incipient moisture present or during steam stripping of any solvent pressure. Treated fabrics and yarns may also be steam treated. The treatments are particularly applicable to polyethylene, polypropylene, copolymers of ethylene and propylene, polystyrene, polyisobutene, polybutadiene, cis-1,4-polyisoprene and styrene/ butadiene random copolymers, and is effective in improving the green strength of conventional vulcanizates formed from such polymers. Example I describes the preparation of trimethylsilyl ester of 3-azidosulphonyl benzoic acid and Examples II and III describe the use of this compound to modify polyisoprene rubbers which are subsequently vulcanized.

Patent GB-745284-A (GB)
Title: Improvements in or relating to the production of catalysts
IPC: B01J23/44
Filed: 1951-11-16
Abstract: Hydrocarbons, e.g. naphthas or gasoline fractions, are hydroformed in the presence of a catalyst prepared by mixing dry activated alumina with a solution of a platinum or palladium compound to form a paste, treating the paste with hydrogen sulphide gas to precipitate the metal, drying, calcining, and reducing with hydrogen (see Group III). Hydroforming is carried out at 600-1000 DEG  F., at pressures between atmospheric and 1000 lb. per sq. inch, and with hydrogen recycle rates of 2000-12000 cubic feet per barrel of feed.  For fixed bed operation a feed rate of 0.25-4 volumes of liquid per volume of catalyst per hour is used and for a fluidized process 0.2-3.5 parts by weight per weight of catalyst per hour.  The catalyst is particularly effective at pressures of 50-200 lb. per sq. inch; carbonaceous deposits formed on the catalyst at these pressures may be removed as described in Specifications 657,565, 745,283 and 745,340, [Group III].  The Specification includes tables, relating to the hydroforming of a virgin naphtha by a fixed bed process, showing operating conditions and characteristics of the products.ALSO:Catalysts for hydroforming hydrocarbons (see Group IV(b)) are prepared by mixing dry activated alumina with a solution of a platinum or palladium compound to form a paste, treating the paste with hydrogen sulphide gas to precipitate the metal, drying, calcining, and reducing with hydrogen.  The alumina may also be treated with a halogen-containing compound, e.g. a fluorine compound or hydrogen chloride, before, after, or together with the solution of the metal compound.  Preferred proportions based on the weight of alumina are platinum 0.1-2 per cent, palladium 0.25-5 per cent, and fluorine, as hydrogen fluoride, 0.25-3 per cent.  In the examples, aqueous solutions of chloroplatinic acid, palladium chloride (containing hydrochloric acid), and hydrogen fluoride are used. Improved catalysts are obtained when the alumina contains 2-8 per cent silica.  The Specification also describes, for comparative purposes, the preparation of catalysts by a similar method, but starting with a wet alumina gel.  The catalysts may be in pill or powder form and may be used in fixed bed, moving bed, or fluidized processes.  When hydroforming is carried out at below 500 lbs. per sq. in pressure, the catalyst may be regenerated as described in Specifications 657,565, 745,283, and 745,340 are referred to.
