Abstract: 1,142,308. Perborates. ALPINE CHEMISCHE A.G. 17 May, 1966 [20 May, 19651, No. 21836/66. Heading C1A. Perborates are produced by oxidizing in a liquid organic medium containing a solid borate (which is substantially insoluble in the medium) and water (which is dissolved in the medium and/or is present as borate water of crystallization), a compound containing per molecule at least two hydrogen atoms which oxidize with the formation of hydrogen peroxide, the oxidation being effected with a molecularoxygen-containing gas such as air. The oxidizable compound may be a hydrazo compound (e.g. hydrazobenzene), an aminophenol or a hydroquinone (e.g. anthrahydroquinone, 2- ethylanthrahydroquinone), and may be regenerated by reduction after the reaction. The organic medium preferably dissolves a high concentration of the oxidizable compound and its oxidized form, and should dissolve at least a small volume of water; it may be an alcohol, ether, ester, or ketone or a mixture of these and hydrocarbons. The water concentration in the reaction mixture is preferably at least 2 mols per mol of borate, but if too high a sticky mass is obtained instead of a particulate product. The water concentration can be further adjusted by means of the amount of moisture in the molecular-oxygen-containing gas. The preferred starting borate is sodium metaborate, which is preferably used in the proportion of 0À6-2 mols per mol of theoretically obtainable hydrogen peroxide. The reaction may be conducted at 10-60‹ C.

Abstract: 370,301. High potential switches. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl- Ufer, Berlin.) Aug. 7, 1931, No. 22416. Convention date, Aug. 7, 1930. [Class 38 (v).] Latching. - In order to prevent opening of the circuit at a gasblast switch when inadequate blastpressure for safe rupture of the arc is available, a pressure piston valve c at a certain minimum pressure admits the gas pressure from the container a to the diaphragm of a pressure responsive device to open, rapidly and with considerable force, a switch in the tripping-control circuit of the breaker. As the pressure in the container falls off the piston c is pressed downwards exposing the passage e to the pressure which distorts the diaphragm f and forces the spring-controlled rod g into engagement with the contact-arm i. Closure of the switch n, which is normally effective to trip the circuit-breaker, leaves the breaker unaffected. The valve arrangement described may lock closed a valve controlling the supply of pneumatic pressure for the opening movement.
