Title: Improvements in or relating to the preparation of a poly(epoxyalkoxyaryl)propane
IPC: C07D301/28
Filed: 1959-08-24
Abstract: Heat-resistant resinous solids are obtained by heating poly (epoxyalkoxyaryl) propanes having 3 or 4 epoxyalkoxyaryl radicals two of which are attached to the internal carbon atom of the propane chain, after addition of epoxy resin curing agents, such as dicyandiamide, mono- or polyamines and polycarboxylic acids and anhydrides.  The polyepoxyalkyl ethers may be mixed with fillers, solvents including monoepoxy compounds, pigments, plasticizers, phenolic resins, urea resins and melamine resins.  In Example (4), the tetraglycidyl ether of 1, 2, 2, 3-tetra (hydroxy-phenyl) propane is melted and added to melted meta-phenylenediamine, the resulting mixture is stirred cast into samples and allowed to cure.  The resulting solids are compared with cured samples of the glycidyl ether of 1, 1, 2, 2-tetra(hydroxyphenyl) ethane.  In Example (5) an acetone solution of the same glycidyl ether and of either a BF3/monoethylamine complex or a mixture of methyl endomethylene tetrahydrophthalic anhydride and benzyl dimethylamine was used to make a glass cloth laminate (see Group VIII).ALSO:The invention comprises a poly(epoxyalkoxyaryl) propane having 3 or 4 epoxyalkoxyaryl radicals two of which are attached to the internal carbon atom of the propane chain.  The novel compounds may be made by reacting an appropriate polyphenol propane such as 1,2,2,3-tetrakis(hydroxyphenyl)propane, 1,2,2tris(hydroxyphenyl)propane or ring-substituted polyphenols, or 1,2,2-tris-(2-hydroxynaphthyl) propane, with an epoxyhalide, such as epichlorohydrin, 1-chloro-3,4-epoxybutane, 1bromo-4,5-epoxypentane; 1- iodo- 5,6- epoxyhexane, 1-bromo-2,3-epoxybutane, 1-chloro-3,4epoxypentane, and 1-iodo-4,5-epoxyhexane, preferably in an amount of 2 to 10 moles per phenolic hydroxyl group.  The reaction may be effected in the presence of an alkali metal hydroxide, the mixture being heated to reflux, and water being distilled off azeotropically with epichlorohydrin.  The polyphenols used as starting materials are prepared by condensation of a phenol, such as phenol, cresol, 2,6-di-tbutyl phenol or napthol with a terminally halogenated acetone, such as mono- or dichloro acetone, preferably with acidic catalysts such as mineral acids, organic carboxylic acids or solid acidic ion exchange resins.  Examples describe the preparation of 1,2,2-tris(hydroxyphenyl)propane, and 1,2,2,3-tetra(hydroxyphenyl) propane and the formation of the glycidyl ether of the latter with epichlorohydrin.  The epoxy products may be hardened to heat-resistant resinous solids (see Group IV(a)).

Abstract: 1532235 Coloured anodizing aluminium ALCAN RESEARCH & DEVELOPMENT Ltd 10 Dec 1975 [16 July 1975] 29936/75 Heading C7B An Al or Al alloy article having a porous anodic oxide film at least 3Á thick on its surface is electrolytically coloured by means of optical interference effects by post-treating the oxide film so that it has average pore size of at least 260 at a distance from the Al/Al oxide interface within the range 500 to 3000 prior to electro-depositing inorganic pigmentary deposits in the pores of the film to a depth such that the separation between the interface and the outer ends of the deposits is in the range 500 to 3000 and the average cross-section of the deposits at their outer ends is at least 260. For example, an Al-Mg-Si alloy extrusion, degreased in an alkaline cleaner, etched in NaOH solution and desmutted, is anodized at 17 volts DC in H 2 SO 4  electrolyte to form an oxide film 15Á thick. The average pore diameter is increased to the required amount e.g. 300 or higher, at least at the base adjacent the barrier layer, by the post-treatment preferably by (a) electro-chemical dissolution e.g. in H 3 PO 4  with or without oxalic acid at 8 to 50 volts DC or chemical dissolution e.g. with H 2 SO 4 , HNO 3 , H 3 PO 4  or NaOH reagent; and/or (b) growth of additional anodic oxide film of larger pore diameter beneath the existing oxide film e.g. by continuing anodizing in excess of 35 volts. The pigmentary material (metal and/or oxide) may be electro-deposited using (interrupted) AC or DC from a bath containing Ni, Co, Sn, Cu, Ag, Cd, Fe and/or Pb salt. The coloured anodized A1 article may be sealed in boiling water.

Title: Hydrocarbon separation process
IPC: C10G67/02
Filed: 1950-12-07
Abstract: A hydrocarbon mixture is subjected to a primary separation to yield an aromatic-rich and an aromatic-lean fraction, the aromatic-lean fraction is subjected to selective adsorption to remove substantially all aromatics, the solid adsorbent after use is regenerated by washing with the aromatic-lean fraction at elevated temperature and the effluent from the solid adsorbent during regeneration is recycled to the primary separation. Hydrocarbon mixtures mentioned include petroleum distillates, such as kerosene, and cracked and reformed naphthas.  The aromatic-rich fraction obtained may constitute a toluene or xylene of high purity.  The primary separation may be solvent extraction with liquid sulphur dioxide, furfural or nitrobenzene as the solvent, a "Duosol" extraction employing propane and phenol-cresol mixture as the solvent, an extractive distillation with a solvent such as phenol, or an azeotropic distillation using for example methyl ethyl ketone and water to form the azeotrope. Adsorbents mentioned are silica gel, alumina gel, silicaalumina gel and activated carbon or charcoal.  In the examples, petroleum kerosene distillate is first solvent-extracted with liquid sulphur dioxide and then contacted with silica gel according to the above-described process.ALSO:A hydrocarbon mixture is subjected to a primary separation to yield an aromatic-rich and an aromatic-lean fraction, the aromatic-lean fraction is subjected to selective adsorption to remove substantially all aromatics, the solid adsorbent after use is regenerated by washing with the aromatic-lean fraction at elevated temperature and the effluent from the solid adsorbent during regeneration is recycled to the primary separation.

[A Specification was laid open to inspection under Sect. 91 of the Acts, May 3, 1935.] [Class 20 (i)] [See also Groups XI and XX] A traffic warning-lamp comprises a shell 1 formed with a large number of perforations 11 disposed closely together and fitted with glass members 12 which receive light from a source 13 arranged centrally within the shell and which also serve as reflex reflectors for light from external sources. The light source 13 may co-operate with a reflector 22, with or without an opposing reflector 21, and the inner surface of the shell 1 may be white enamelled or otherwise made reflecting. The shell 1 may be formed of thin sheet metal and the perforations 11 may have sunk edges in which are cemented offset edges on the glass members 12 so that the outer surfaces of the latter lie flush with the outer surface of the shell. The members 12 are made of glass having a high index of refraction so as to act with double total refraction, they may be coloured, and they may be of conical formation with apex angles of 90‹, or they may be in the form of vertically or horizontally disposed straight or curved prisms having two rear surfaces at 90‹ to each other. The shell 1 is mounted on a pedestal 4 having a conical or spherical circular recess 7 which rests loosely on a correspondingly shaped projection 8 on a base-plate 6 which is secured to a foundation 5 by means of bolts 9. Alternatively, the lower end of the pedestal may be surrounded by the projection. In each case, the lamp is easily knocked over by a vehicle, but in order to resist wind and like normal pressures, readily sheared transverse bolts or the like 29 may be employed. Fig. 5 shows a shell 1 having a thicker wall made of iron or concrete and provided internally with conical indentations 24 having reflecting surfaces. Comparatively soft mortar 28 is poured between the lower end 27 of the shell and a projection on the base-plate 6 which rests on the ground and is secured against tilting by means of an anchor post 26 driven through a central aperture 25 in the base-plate.
