Abstract: Procédé de préparation d'acétate de méthyle de grande pureté à des taux élevés de conversion de réactifs. Dans ce procédé on fait réagir de l'acide acétique cristallisable avec du méthanol pour former de l'acétate de méthyle et l'acide acétique cristallisable est utilisé également comme agent d'extraction pour l'eau et/ou le méthanol. On fait réagir en continu l'acide acétique cristallisable avec au moins une quantité stoechiométrique de méthanole dans une zone de réaction en présence d'un catalyseur acide. Un courant d'acétate de méthyle est extrait en continu de la zone par distillation. L'acide acétique cristallisable et le méthanol s'écoule à contre-courant dans la zone de réaction et le temps de résidence des liquides de réaction dans la zone est sélectionné pour permettre à l'acide acétique cristallisable de servir d'agent extracteur pour l'eau et/ou le méthanole. Pendant le fonctionnement, un contact intime a lieu entre l'acide acétique cristallisable et le méthanol et également entre l'acide et les azéotropes (azéotropes d'acétate de méthyle et/ou azéotropes d'acétate de méthyle/méthanol) qui se forment dans la zone de réaction. Ces azéotropes sont "cassés" par l'extraction au moyen de l'acide acétique cristallisable et également par la réaction entre cet acide et le méthanol dans les azéotropes d'acétate de méthyle/méthanol.

Abstract: The known nuclear hydroxylation of substituted phenols or phenol ethers with organic solutions of hydrogen peroxide in the presence of a catalyst is carried out in improved manner by employing both (1) a special, practically water free solution of hydrogen peroxide in an organic solvent which forms an azeotrope with water, which azeotrope boils below the boiling point of hydrogen peroxide, and (2) sulfur dioxide as a catalyst. Through this, the nuclear hydroxylation is substantially simpler than previously; difficult separations, e.g., from water-phenol, or the separation and recovery of the catalyst are eliminated. Besides, the yields are increased.

Abstract: In an apparatus having a record mode for recording video or other information signals in successive parallel information tracks on a record tape by means of a plurality of rotary heads repeatedly scanning across said tape and having respective gaps with different azimuth angles, and in which the apparatus is changeable to a playback mode for causing each of said heads to provide a respective output when it is scanning an information track in which information signals have been previously recorded by a head with a gap having the same azimuth angle; clogging of one or more of the head gaps which would prevent further recording is detected, in the playback mode, by switching from one to another of the outputs of the heads during each period required forthe scanning of the tape by each of the heads, detecting the levels of the head outputs during such switching therebetween, and operating a clog indicator when the detected levels of the head outputs are insufficient during the scanning of the tape by each of the heads. In order to avoid a false clog indication, the operation of the clog indicator is inhibited when the usual fixed head does not reproduce control signals in the playback mode, for example, as when there has been no previous recording of information signals on the record tape.

Abstract: @ Locking pins are usually in the form of so called split pins. These pins are impaired by the disadvantage that they normally can be used only once and very often do not form a distinct locking position in the axial direction for the shaft locking which the pin is intended to perform. These disadvantages are eliminated in that the pin (1) is formed from an elastic material, that it in its longitudinal direction has a symmetry plane, the section of which through the pin forms two opposite outlines (3,5) one of which (3) bends outwardly. The bentout outline has a peak height (12) measured from an opposite straight line (13), which connects two end points of the second outline of the locking pin, which peak height (12) is larger than the diameter of the bore, into which the locking pin is to be inserted. The wall thickness of the pin is overall less than the diameter of the bore, whereby at least one of said end points (at 6,7) are placed on the end portion of a shoulder (6,7), which is formed at the end of the pin.
