Patent EP-0146659-A1 (EP)
Inventor: OKAMOTO HARUO
IPC: C03B37/014
Filed: 1983-12-22
Abstract: The invention provides a novel method for the preparation of a synthetic quartz glass body substantially free from hydroxy groups as a class of undesirable impurities when the quartz glass body is used as a precursor of optical fibers. The method comprises subjecting a gaseous mixture composed of a silicon compound and a fluorine-containing hydrocarbon compound such as carbon tetrafluoride and trifluoro chloromethane to combustion or thermal decomposition in an oxidizing condition to form silicon dioxide which is deposited on the substrate to form a porous sintered body to be subsequently melted into a transparent quartz glass body. When the silicon compound and the fluorine-containing hydrocarbon compound contain no chlorine atoms, the resultant quartz glass body is also free from chlorine impurity undesirable in optical fibers. The above principle is applied to the direct preparation of a precursor rod of optical fibers by conducting the combustion or oxidative decomposition of the silicon compound in the space surrounded by the inner wall of a quartz glass tube outwardly heated at such an intensity that the silicon dioxide is deposited in transparent quartz glass layers.

Abstract: Dans un procédé de sustentation d'un toit en tôle métallique, la tôle (1) constitue une couche imperméable superficielle et est ondulée de préférence en forme trapézoïdale, de la façon connue. Les crêtes avec une section transversale trapézoïdale s'étendent dans le sens de la longueur de la tôle, et des creux trapézoïdaux sont situés entre les crêtes. Ledit sens de longueur s'étend sensiblement en parallèle avec le sens de sustentation, le sens de la largeur, du toit, et la tôle est au moins en connexion avec les bords longitudinaux (23) du toit, posés sur des poutres de sustentation (4) ou éléments correspondants agencés perpendiculairement audit sens de la largeur. Le procédé se caractérise spécialement par le fait que la charge du toit ou d'une section du toit est soutenue en tant que forces de traction par des barres (27, 29) qui s'étendent entre les bords longitudinaux (23) du toit ou d'une section du toit. Des forces de réaction sensiblement correspondantes auxdites forces de traction sont appliquées sur la tôle (1) en tant que forces de compression s'exerçant dans le sens longitudinal de la tôle en attachant lesdites barres à la tôle, ou au moins à ses bords longitudinaux, ce qui fait que la capacité de ladite tôle ondulée de recevoir des forces de compression s'exerçant dans le sens de sa longueur est utilisée pour soutenir le toit. L'invention porte également sur une armature de toit pour appliquer le procédé.

Abstract: Die an sich bekannte Kernhydroxylierung von Phenol mit organischen Lösungen von Wasserstoffperoxid in Gegenwart eines Katalysators wird sowohl mit speziellen, praktisch wasserfreien Lösungen von Wasserstoffperoxid in Lösungsmitteln, die mit Wasser Azeotrope bilden, die unterhalb des Siedepunktes von Wasserstoffperoxid sieden, wie auch mit Schwefeldioxid als Katalysator durchgeführt. Hierdurch läßt sich die Kernhydroxylierung wesentlich einfacher als bisher durchführen; schwierige Trennungen, z.B. von Wasser-Phenol, oder die Abtrennung und Rückgewinnung des Katalysators fallen fort. Außerdem sind die Ausbeuten gesteigert.

Abstract: In separating a mixture of solid material particles including non-magnetic electrically conductive metals into a light fraction and a heavy fraction, where the light fraction includes the non-magnetic particles, the mixture is directed into an upwardly extending airflow passageway from an inlet channel extending laterally from the passageway. The inlet channel is spaced between the inlet and outlet ends of the passageway. An alternating magnetic field is provided adjacent the entrance of the mixture into the airflow passageway for accelerating the particles in the desired direction. The mixture is fed through the inlet channel into the airflow passageway in layer form, preferably as a single layer. A main flow of air passes upwardly through the airflow passageway from the lower inlet end and develops a highly turbulent vortex-like airflow. The airflow, in combination with the magnetic field, effects separation of the light and heavy fractions of the material. A secondary flow of air is directed upwardly into the air flow passage in the region of the introduction of the mixture and accelerates the air flow and carries the light fraction upwardly to the outlet end of the passageway.
