Title: Improvements in electric discharge devices comprising an evacuated envelope containing a luminescent screen
IPC: H01J29/28
Filed: 1936-08-25
Abstract: 479,306. Electrode materials. GENERAL ELECTRIC CO., Ltd. (Patent-Treuhand-Ges. f³r Elektrische Gl³hlampen) Aug. 25, 1936, Nos. 23328 and 24137. [Class 39 (i)] [Also in Group XX] In an evacuated or gas-filled discharge device having a luminescent screen which becomes electrically charged by the agency (e.g. cathode rays) which produces luminescence, the screen is deposited on an oxide underlayer having an absorptivity for visible light not substantially greater than that of zinc oxide, and a resistivity not greater than 100 ohms per cm. cube, in order to conduct away the electric charge. The oxide may be commercial zinc oxide or niobium oxide. It may be formed on a glass surface provided with an electrode which may be a metallic layer burnt into the glass near the boundary of the oxide layer, whereby it may be maintained at the desired potential ; or if the screen is to be viewed from the side on which the exciting agency falls, the oxide layer may be formed on an opaque metallic conductor, e.g. platinum which may be highly polished. The layer may be produced by spraying the powdered oxide, or by oxidizing a metal layer, or by cataphoresis; and its conductivity may be improved by a trace of a reducing binder, such as gum tragacanth or cellulose acetate, or by exposure to a discharge through a reducing gas such as hydrogen. If the luminescent layer shares a metal with the oxide layer, the luminescent layer may be formed from the underlying oxide by chemical surface treatment. Thus a sintered plate of zinc oxide containing a few tenths of 1 per cent of manganese may be coated thinly with silica and heated to 1000-1200‹ C. to form a surface layer of zinc silicate activated with manganese ; or a plate of zinc oxide containing silver as impurity may be converted superficially into zinc sulphide activated with silver by heating it in hydrogen sulphide at about 400‹ C. Specifications 449,392, 458,635, and 460,756, [all in Group XX], are referred to. Reference has been directed by the Comptroller to Specification 458,635.

Title: Improvements in or relating to the manufacture of ethers of phenylmethylcarbinol andits homologues, and the decomposition thereof
IPC: C07C41/06
Filed: 1938-08-10
Abstract: 517,934. Hydrocarbons ethers. DISTILLERS CO., Ltd., STANLEY, H. M., MINKOFF, G., and YOUELL, J. E. Aug. 10, 1938, No. 23597. [Class 2 (iii)] Ethers of phenylmethylcarbinol and its homologues are made by condensing an arylsubstituted mono-olefine, e.g., styrene, alphamethylstyrene, and p-isopropylstyrene, with an alcohol in the presence of an acid condensing agent, e.g., sulphuric acid, perchloric acid or chloracetic acid. A polymerisation inhibitor, e.g., pyrogallol, is preferably added to the reactants. After the condensation, the condensing agents are removed or neutralised, e.g., by addition of triethanolamine, and the ether is separated by fractional 'distillation. The invention is particularly applicable to the separation of styrene and its homologues from mixtures containing them, such as the styrenecontaining mixtures obtained by, thermal decomposition of hydrocarbons, e.g., ethyl- and isopropyl-benzene, the styrene in such mixtures being converted into an ether of phenylmethyl-' carbinol which is separated and finally decomposed into styrene and the alcohol by heating with a catalyst, consisting of an acidreacting salt, an alkyl sulphuric acid, boric acid or a phosphoric ester, or by vapour-phase decomposition in the presence of solid contact substances such as pumice stone, kieselguhr or aluminium silicate. In examples, (1) a mixture containing styrene and isopropylbenzene is condensed with methyl, ethyl, isopropyl or nbutyl alcohols to give the corresponding ethers of phenylmethylcarbinol, and (2) alpha-methylstyrene is condensed with n-butyl alcohol to give the n-butyl ether of phenyldimethylcarbinol.
