Title: Process for the production of aliphatic and cycloaliphatic oximes
Filed: 1951-05-23
Abstract: In a process for the production of oximes from alkali or alkaline earth metal salts of the primary or secondary nitro-compounds of the aliphatic or cycloaliphatic series a solution or suspension of the salt in an organic solvent or suspension agent is treated with nascent hydrogen or hydrogen in the presence of a hydrogenation catalyst, if necessary under pressure, while maintaining an acid reaction.  Nitrocompounds mentioned include nitroethane, 1-nitropropane, 2-nitropropane, 1- and 2-nitrobutane, the various isomeric mononitropentanes and mononitrohexanes, nitrocyclohexane and 1-nitro-2-methylcyclohexane.  The salts are obtained in the known manner, e.g. by treating the nitro-compound with metal hydroxides. Organic solvents or suspension agents mentioned include alcohols such as methyl, ethyl, propyl and butyl alcohols, aliphatic hydrocarbons such as cyclohexane, methylcyclohexane and methylcyclopentane, carbon tetrachloride and chloroform.  Nascent hydrogen may be produced by means of a metal in a solution of the salt of the nitrocompound to which is added an aqueous acid, e.g. hydrochloric acid or sulphuric acid.  In the catalytic reduction known hydrogenation catalysts may be employed, those mentioned being the metals, metal oxides and metal sulphides of the sixth and eighth groups of the periodic system.  In examples: Cyclohexanone oxime is produced with cyclohexylamine, cyclohexylamine hydrochloride, cyclohexanone and cyclohexanol as by-products on reducing the sodium salt of nitrocyclohexane in aqueous methanol with hydrochloric acid and zinc dust suspended in aqueous methanol (1) and acetaldoxime and ethylamine are produced by spraying a methanol solution of nitroethane into a heated autoclave containing nickel catalyst suspended in methanolic acetic acid and hydrogen under pressure (2).

Abstract: 873,548. Magnetizing and demagnetizing apparatus. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 6, 1960 [April 9, 1959], No. 12221/60. Class 35. A magnetizing coil 7, into which a capacitor 1 may be discharged, is critically damped by a resistor 8 which has a rectifier 9 in series with it so that it is operative only when the potential across the coil reverses, i.e. at the end of a discharge. The capacitor is first charged from a D.C. source at 3, 4 and is then connected to the coil 7 either by a mechanical switch and a diode or a thyratron 5, triggered by removing a blocking voltage at 12. The rectifier 9, which may be a gas-filled diode, blocks the damping resistor 8 whilst the coil current is building up, then becomes conducting during decay, the resistor 8 then preventing overshoot. By rearranging switches 10, 11, 13 the thyratron may be short-circuited and the damping circuit disconnected to allow the coil 7 and capacitor 1 to ring, the device then being used for demagnetization.

Filed: 1945-05-16
Abstract: A lightweight, shape-retaining insulating product is obtained by introducing gas into an aqueous solution of a protein, an inorganic tanning agent and a foaming agent, shaping the foam produced and drying the shaped foam.  An improved product is obtained by incorporating into the solution before the shaping a fibrous material such as wood pulp, alpha-cellulose fluff, asbestos, or rock or glass wool.  The foaming agent is preferably an anion-active surface tension lowering agent, e.g. a sodium salt of an alkyl aryl sulphonate or sulphated alcohol.  Glue is the preferred protein but egg albumen or soyabean protein may be used in conjunction with a solubiliser.  Suitable tanning agents are the basic sulphate, the acetate and chloride salts of chromium, aluminium and ferric sulphates and alkali metal or ammonium hypochlorites, tungstates and molybdates.  The gas used is air and is preferably introduced at a temperature of between 30 DEG  - 100 DEG  C.  Waterproofing agents, e.g. asphalt, wax emulsions and water-repellent soaps may be added. Generally the foam is shaped into a board on a sheet element such as Kraft paper to which it adheres on drying.  Fillers, e.g. admixed clay, plasticizers etc., may be included in the compositions.
