Abstract: 1,080,166. Winding webs. KEELAVITE HYDRAULICS Ltd., & BERTRAMS Ltd. July 15, 1964 [May 3, 1963], No. 17646/63. Heading B6B. In a two-drum web winding machine, the spindle 14 of the web-roll 1 is supported in bearings 15 in the lower ends of a pair of piston rods 16 of a pair of hydraulic cylinders 18. The cylinders 18 initially load the web-roll to engage the drums with an adjustable predetermined nip-pressure. As the web-roll increases in diameter the increase in weight is relieved by the cylinders with an increase in pressure in the pressure chamber 20. The increase in weight is detected by one of the drums 3 which is mounted in a pair of levers 6 pivoted at 7. The levers are loaded by an hydraulic cylinder 11. The chambers 19 and 13 of cylinders 18 and 11 are connected to a common source of adjustable pressure. The cross-sectional areas of the chambers 19 and 13 and the leverage ratio of the levers 6 are such that with an empty webroll shell supported on the drums 2 and 3 the forces applied to the levers counterbalance. The amount of movement of the levers 6 is limited by adjustable stops 6a. The movement of the levers 6 due to increase in weight of the web-roll 1 is detected by a movable member 38 of a sensitive control device 39 by which the pressure in a hydraulic system including the pressure chambers 20 is controlled.

Title: Processes for the production of 3-cyanopyridine
Filed: 1942-12-15
Abstract: 3-Cyano-pyridine is made by heating an alkali or alkaline earth metal salt of pyridine-3-sulphonic acid with a mixture of sodium and potassium cyanides or ferrocyanides in the presence of an inert organic material liquid at the reaction temperature, to about 310 or 410 DEG  C., depending on whether an alkali or alkaline earth metal salt is used, condensing the vapours and purifying by vacuum distillation.  The inert organic material may be petrolatum, liquid or solid paraffin or a mineral oil of high flash point boiling above the distillation temperature of the nitrile.  In examples, the sodium and/or potassium salt of pyridine-3-sulphonic acid is mixed with sodium and potassium cyanides in various ratios or with sodium cyanide and potassium ferrocyanide, and added to high-boiling mineral oil in a retort. Part of the oil decomposes and begins to distil at 250, and reaction is complete at about 310 DEG  C.  The condensate is ice-cooled to solidify the nitrile which is separated from the oil and vacuum distilled.  The calcium sulphonate is similarly treated, the reaction temperature being about 410 DEG  C.

Abstract: 792,920. Printed circuits. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 22, 1955 [June 25, 1954], No. 18067/55. Class 37. A printed circuit is made by electroplating a separable metal layer 2 of a thickness not exceeding 10 microns on a temporary metal base-plate 1, providing a non-conductive resist 3 to the metal layer in the negative image of the desired pattern, depositing metal 4 on the uncovered parts of the metal layer 2, applying the patterned side of the base to an insulating layer 5, separating the base 1 from the layer 2 and removing the layer 2 by chemical and/or mechanical action. The plate 1 may be of stainless steel and the layer 2 of copper. The resist 3 may be formed by covering the layer 2 with polyvinyl-butyral rendered light-sensitive by ammonium chromate. This is exposed under a transparency of the desired pattern, the non- exposed portions being subsequently removed. The pattern 4 may be deposited on the uncovered copper by electroplating, if desired in two layers, for example a layer of rhodium, gold, silver or tin-lead alloy, followed by copper. The insulation 5 may comprise a stack of paper soaked in cresol resin against which the patterned base 1 is pressed in a heated press which cures the resin and presses the pattern into the insulation. The steel plate is removed from the copper layer 2 and the latter is dissolved in a ferric chloride bath. The resist 3 is swollen in ethanol and then removed mechanically. Alternatively, the resist 3 may be removed before the pattern is transferred to the insulation 5. Specification 639,178 is referred to.

Title: A process for preparing polymethylbenzenes containing at least three methyl groups, particularly durene
IPC: C07C6/12
Filed: 1955-06-22
Abstract: A polymethylbenzene containing at least three methyl groups is prepared by (1) methylating a methylbenzene containing either 1, 2 or 3 methyl groups with methanol in the vapour phase and in the presence of an acidic catalyst under conditions to yield a methylation product containing tetramethylbenzenes and higher polymethylbenzenes; (2) subjecting said methylation product to distillation to separate a durene containing tetramethylbenzenes fraction and a higher boiling fraction containing higher polymethylbenzenes; (3) recovering durene by crystallization from the tetramethylbenzenes fraction with separation of an isodurene-and prehnitene-containing mother liquor; (4) subjecting a mixture comprising said higher polymethylbenzenes fraction or a portion thereof and one or more methylbenzenes each containing either 1, 2 or 3 methyl groups to transmethylation at a temperature between about 425 DEG  and 500 DEG  C. in the presence of an acidic catalyst to produce a transmethylate containing tetramethylbenzenes; and (5) returning said transmethylate to separation step (2).  In a preferred modification the transmethylate produced in step (4) is subjected to distillation to separate an intermediate fraction consisting essentially of tetramethylbenzenes, and the intermediate fraction is combined with the tetramethylbenzenes fraction produced in the separation step (2) prior to the recovery of durene therefrom by crystallization. Specified polymethylbenzenes containing at least 3 methyl groups which may be produced are pseucumene prehnitene, durene and pentamethylbenzene.  The transmethylation step may be carried out in contact with a solid acidic catalyst such as hydrogen fluoride-treated alumina, acidic silica-alumina, hydrogen-fluoride treated silica alumina and aluminaboria at temperatures of about 475 DEG  C.  Isomerization may be effected by the same or a more acid catalyst.

Title: Process for the production of synthetic resins from alcoholamines and organic acids
IPC: C08G63/685
Filed: 1931-06-23
Abstract: To the polycarboxylic acid used in the parent case is added a resin acid, i.e. all natural or artificial resin-like products which contain one or more free carboxyl groups or unsaturated fatty acid of the higher series as derived from natural fats or oils which acids may be partly or completely esterified with alcohols, preferably with polyhydric alcohols.  The products may be employed as plasticizing agents for oil varnishes, cellulose derivative varnishes and as plasticizers and catalysts in the manufacture of phenol-aldehyde resins.  As resin acids may be used colophony, Kongo copal, Manila copal, Kauri copal, the acid synthetic resins obtained by the condensation of natural resins with phenol-formaldehyde condensation products and the purely synthetic acid resins such as the condensation products of salicylic acid and formaldehyde.  As unsaturated fatty acids there may be used the acids of drying oils such as linseed oil fatty acids, wood oil fatty acids or castor oil fatty acids, their glycerol esters such as the oils themselves or their esters with other polyhydric alcohols such as glycol, polyglycol, polyglycerol or mannite, the alcohols being partially or wholly esterified such as monoricinoleic acid glycol ester, mono- or di-linseed oil acid glycerol ester.  In examples (1) succinic acid, French colophony and diethanolamine are heated together giving a resin soluble in ether, acetone, ethylacetate, benzol and benzine and capable of forming a film with a nitrocellulose varnish.  (2) Technical triethanolamine and linseed oil acids are heated together to give a product insoluble in water which is further heated with phthalic acid anhydride.  (3) Adipic acid, French colophony and triethanolamine are heated together to give a product suitable as a softening means for nitrocellulose varnishes.  (4) Phthalic acid anhydride, adipic acid, French colophony and tributanolamine are heated together.  (5) Phthalic acid anhydride, French colophony, monoethanolamine, and glycerol are heated together giving a resin which forms weatherproof nitrocellulose varnish films with nitrocellulose wool.  (6) Phthalic acid anhydride, diethanolamine, a polymerized glycerol such as diglycerol and the acid resin produced in accordance with Specification 259,030 but not neutralized by alcohols or metal oxides are heated together. (7) Colophony, phthalic acid anhydride and diethylmonoglycerylamine are heated together giving a resin soluble in acetone, ethylacetate, benzol and diethyl ether but insoluble in alcohol.  With nitrocellulose and suitable solvents it yields light-resisting varnishes or lacquers. Specification 259,030, [Class 2 (iii), Dyes &c.], is referred to.
