Abstract: 1,211,275. Process for the dehydrohalogenation of a beta-haloalkyl phosphonate. STAUFFER CHEMICAL CO. 22 March, 1968 [7 April, 1967], No. 13930/68. Heading C2C. A process for the dehydrohalogenation of a beta-haloalkyl phosphonate comprises heating the beta-haloalkyl phosphonate at a temperature of from 90 to 130 C. in the presence of a catalyst system comprising an alkali metal carbonate and an organic acid having a pH value of from 1 to 6 measured as a 0À1 N solution at 25 C. and in a molar ratio of from 25 : 1 to 2 : 1 carbonate to acid. The process is applicable to compounds of the formula where n and in are 0 to 6, X is a halogen atom having a molecular weight greater than 30, e.g. chlorine, bromine or iodine, R and R<SP>1</SP> are hydrocarbyl groups which may be substituted and containing 1 to 18 carbon atoms, R<SP>11</SP> is hydrogen or is a hydrocarbyl group which may be substituted and contains 1 to 18 carbon atoms. Organic acids containing 1 to 12 carbon atoms are preferred, especially organic carboxylic and phenolic acids, e.g. benzoic, hexahydrobenzoic, heptanoic, propionic, chloroacetic and acetic acids, and phenol, pentachlorophenol and dinitrophenol. Specified carbonates and bicarbonates are those of lithium, potassium, sodium and ammonium. The reaction may be conducted in the presence of an inert solvent, and a foam depressant is desirably added. Examples are given of the dehydrohalogenation of chloroethyl bis-2-chloroethyl phosphonate to form bis-2-chloroethyl vinyl phosphonate. The organic acid may be replaced by an alkali metal salt of the acid.

Abstract: 692,694. Inductors. DEPARTMENT OF COMMERCE, DIRECTOR OF THE OFFICE OF TECHNICAL SERVICES OF. June 1, 1948 [June 23, 1947], No. 14775/48. Class 38 (ii). [Also in Groups XXXVI and XL (a)] Inductance coils are printed or otherwise deposited either directly on to the surface of a valve envelope, on to an insulating enamel applied to said surface, or on to a tubular body surrounding the valve. The inductance may be increased by printing between the turns of the coil 61, intervening lines 62 in an ink or paint containing a substantial amount of magnetic material, the width and thickness of these lines determining the degree of concentration of flux. Alternatively, non-conductive magnetic material may be sprayed on the coil and intervening areas of the envelope between the turns of the coil. Conductive magnetic material may be sprayed or painted over a high dielectric varnish covering the coil. Where the coils are formed on the outer surface of a tubular body surrounding the valve, the inner surface may be provided with a magnetic coating. The Specification as open to inspection under Sect. 91 describes producing coils by printing straight lines 110, Fig. 22 (Cancelled), on a flat sheet 111 and then curving the sheet and joining opposite edges so that the end of one line registers with the opposed end of the next line to form a helix, continuity being effected by a spot of solder at each junction. Alternatively, a zig-zag conducting line 101, Fig. 24 (Cancelled), may be printed on sheet 100 which has slits 102. The sheet is then deformed by bowing transverse strips 103 in opposite directions to form the sheet 100 into a cylinder and thus the line 101 into a helix. This subjectmatter does not appear in the Specification as accepted.
