Title: A method and means for heat treating a toothed convex surface of an article by high frequency induction heating
Inventor: FROST LEONARD FRANK
IPC: H05B6/02
Filed: 1955-04-15
Abstract: 831,271. Induction heating. DELAPENA & SON Ltd. April 13, 1956 [April 15, 1955], No. 10963/55. Class 39(3) Apparatus for heat treating toothed convex surfaces of articles, e.g. the periphery of a gear wheel or segment, by high frequency induction heating, is as described in Specification 831,269 and includes a dummy inductor 31 of slightly larger profile than an inductor 11, the dummy being used to set the angular position of the article about the axis of the convex surface to enable the inductor to enter a tooth space in an exactly symmetrical manner. In setting up the apparatus, the dummy indicator is substituted for the inductor 11 between guides 30, and a sliding element 23 adjusted until both the dummy inductor and a pin 37 of a locating element 36 lie opposite a tooth space 33 of the gearwheel 12 being treated, i.e. within the thickness of the gearwheel. The dummy inductor is then moved into the tooth space 33 by horizontal adjustment of a carriage (not shown) and the gearwheel is thus locked in the angular sense on the shaft on which the gearwheel is rotatably mounted. The pin 37 of the locating element is caused to enter the -tooth space 33 by adjustment of the locating element which, after locking in its adjusted position, is retracted clear of the tooth space. The inductor 11 is then substituted for the dummy 31 by moving the shaft supporting the gearwheel downwardly or by moving the horizontally adjustable carriage outwardly. The dummy inductor is larger in profile than the inductor 11 so that a suitable air gap results as the inductor traverses a tooth space. Subsequent operation of the apparatus is as described in Specification 831,269. Specification 831,270 also is referred to.

Title: Production of hydroxy aromatic ketones
IPC: C07C49/825
Filed: 1974-03-12
Abstract: 1458695 Preparation of alkyl-o- or p alkanoyl phenols SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 12 March 1974 10991/74 Heading C2C The invention comprises a process for the preparation of compounds of the general Formula I in which R<SP>1</SP> represents an optionally substituted hydrocarbyl group, R<SP>2</SP> represents an alkyl group (e.g. 5-1,1,3,3-tetramethyl butyl, 5-tertnonyl, and 5-tert-butyl) having a tertiary or quaternary carbon atom and n is 1, 2 or 3, in which R<SP>1</SP>CO is in an ortho- or para-position relative to the OH group and in which the aromatic nucleus has, optionally, one or more substituents other than -C(O)R<SP>1</SP> or -R<SP>2</SP> groups, by contacting an ester of Formula II wherein R<SP>1</SP>, R<SP>2</SP> and n are as defined above and in which the aromatic nucleus has, optionally, one or more substituents other than -C(O)R<SP>1</SP> or -R<SP>2</SP> groups, with a chloride or bromide-type Lewis acid in the presence of a solvent and, during the course of the reaction, expelling the HCl or HBr formed from the reaction mixture. The expulsion of HCl or HBr may be achieved by boiling and/or passing an inert gas through the reaction solution. p-Alkyl phenols are produced as by-products in some reactions as are methyl 5-alkyl-2- hydroxyphenylketones in which the alkyl group is not the group R<SP>2</SP> present in the starting material but a degradation or other product thereof. Thus methyl 5-tert-butyl-2-hydroxyphenyl ketone, methyl 5-octyl-2-hydroxyphenyl ketone and methyl 5 - alkyl - 2 - hydroxyphenyl ketone are obtained in the product of the reaction of 1,1,3,3-tetramethylbutylphenylacetate, t-butylphenylacetate and tert-nonylphenylacetate respectively and tert-nonylphenol, tertiary butylphenol and octyl phenol are also obtained, the first in the reaction of tert-nonylphenylacetate and the last two from the reaction of tertbutylphenylacetate.

Abstract: Fibre-spinning solutions of relatively low viscosity and good clarity are obtained by dissolving a polymeric material containing 90-98 per cent. acrylonitrile and 2 - 10 per cent. vinyl pyridine groups in a solvent together with 0.01 to 5 per cent by weight, based on the solution, of sulphuric acid or an alkyl ester of an aromatic sulphonic acid, e.g. methyl p - toluene sulphonate.  The polymeric material may be a blend of a polymer or copolymer of acrylonitrile and a polymer of copolymer of vinyl pyridine, or it may be a copolymer of the two monomers.  In the blends, the acrylonitrile may be copolymerised with up to 10 per cent. of the monomers, e.g. vinyl acetate and chloroacetate, alkyl acrylates and methacrylates, alkyl maleates and fumarates, styrene, vinylidene chloride and methacrylonitrile.  The vinyl pyridine may be copolymerised with up to 70 per cent. of another monomer, e.g. acrylonitrile or any of the above mentioned compounds. These compounds may also be used as a third monomer with acrylonitrile and vinyl pyridine in a terpolymeric system.  The vinyl pyridine may be any isomer or may be alkyl substituted, e.g. 2-, 3-, or 4 - vinyl pyridine, 2 - vinyl - 4 - ethyl, 2 - vinyl - 5 -thyl and 3 - vinyl - 5 - ethyl pyridine, 2 - vinyl - 3 - methyl -, 5 - vinyl - 2 - methyl- and 2 - vinyl 4 - methyl pyridine.  Solvents for the polymers include N - N - dimethylacetamide, butyrolactone, N-N-dimethyl formamide, ethylene carbonate, maleic anhydride, N - N - dimethylmethoxyacetamide, succinic anhydride and a  - cyanoacetamide.  Fibres are formed by spinning the solutions into a bath containing, e.g. a mixture of 60 per cent. N, N - dimethylacetamide and 40 per cent. water.  The fibres may then be washed with water, stretched and dried.
