Abstract: 364,457. Electrolytic purification of hydrogen peroxide. OESTERREICHISCHE CHEMISCHE WERKE GES., 5, Technikerstrasse, Vienna. April 8, 1931, No. 10386. Convention date, July 24, 1930. [Class 41.] Hydrogen peroxide is treated in the cathode chamber of a diaphragm cell for removal of acidic impurities or in the anode chamber for the removal of metallic impurities or successively in any order in both. The second electrolyte may be a hydrogen peroxide solution of the same concentration as that to be purified so as to prevent loss by diffusion. Stabilizing compounds may be introduced into the solution being purified by ionic migration ; for this purpose a dilute solution of phosphoric acid or a phosphate or pyrophosphate may be used as catholyte, when the solution to be purified is anolyte. Salts of pyrophosphoric, phosphoric, salicylic and boric acids may be added to a solution to be purified as anolyte, these remaining therein and acting as stabilizers. To maintain the conductivity of the solution traces of unobjectionable compounds such as alkali metal or alkaline-earth metal hydroxides may be added. The solution may be passed through the anode compartments or the cathode compartments of a series of cells; in this case, the other compartments may be supplied only by diffusion and electrolytic transport. In the last cell of a series, a voltage must be maintained sufficient to prevent back-diffusion. For cathodic purification the cathode may be of graphite, tin, aluminium or a special steel and the anode of platinum. For anodic purification the anode and cathode are both of platinum. Detailed examples are given. Specification 349,771 is referred to.

Abstract: 1,197,695. Ultrasonic inspection devices. BRANSON INSTRUMENTS Inc. 5 March, 1968 [22 March, 1967], No. 10644/68. Addition to 1,124,898. Heading H4D. The system of the parent invention is modified in that a polarity sensitive device is provided for initiating the time interval measurement in response to a reflection signal caused by the ultrasonic pulse passing from a material of relatively low specific acoustic impedance to one of higher specific acoustic impedance. This ensures that the measurement is initiated by the reflection at the workpiece entrant surface, and not by the reflection at the interface between the plastics coupling block and the liquid film which couples the block to the workpiece. The entrant surface and block/film interface reflection signals overlap in time to give a composite signal with an initial portion of one polarity and a subsequent portion of opposite polarity. The polarity sensitive device described is a transistor circuit which responds to the subsequent portion only, for initiating a time measurement by the system described in the parent Specification.

Patent GB-690307-A (GB)
Title: Preparation of naphthostyrils
IPC: C07D209/92
Filed: 1951-05-07
Abstract: Naphthostyrils are prepared by reacting an alpha-naphthyl isocyanate or isothiocyanate, which may bear substituents which do not react with Friedel-Crafts catalysts, e.g. chloro, bromo, nitro, hydroxy and alkoxy groups, with a Friedel-Crafts catalyst such as aluminium chloride, aluminium bromide, boron trifluoride or zirconium chloride, preferably in an inert diluent, which may be a solid such as sodium chloride but is preferably an organic liquid such as o-dichlorobenzene.  The reaction may take place at an elevated temperature suitably at 100-200 DEG  C.  In place of an alpha-naphthyl isocyanate, the reaction mixture formed by reaction of phosgene with an alpha naphthylamine may be used.  When the starting material is an isothiocyanate, a thio-naphthostyril is probably formed as an intermediate which is transformed to the naphthostyril by treatment with aqueous alkali and acidification during the separation of the product.  In examples: (1), (2) and (5) alpha-naphthyl isocyanate is reacted with aluminium chloride to give naphthostyril; (3) 1-amino-4-chloronaphthalene is reacted with phosgene followed by aluminium chloride to give 4-chloronaphthostyril; (4) 1-amino-2-methylnaphthalene hydrochloride is treated as in (3) to give 2-methylnaphthostyril; (6) alpha-naphthyl isocyanate is treated with zirconium tetrachloride to give naphthostyril; (7) 1-amino-5-methoxynaphthalene hydrochloride is treated with phosgene followed by zirconium tetrachloride to give 5-methoxynaphthostyril; and (8) alpha-naphthyl isothiocyanate is treated with aluminium chloride to give naphthostyril.
