Patent EP-0521852-A1 (EP)
Inventor: WUEST WILLI DR
IPC: C07C303/44
Filed: 1990-06-19
Abstract: Selon un procédé de production d'acides sulfoniques d'alcane inférieurs à partir de leurs sels alcalins, on fait réagir ceux-ci avec du HCl et on sépare le mélange de réaction. Selon ce nouveau procédé, on mélange les sels alcalins des acides sulfoniques d'alcane, le cas échéant mélangés avec du chlorure alcalin, qui se présentent sous forme d'une boue saline aqueuse concentrée, avec un excédent molaire de HCl plusieurs fois supérieur à la quantité d'acide sulfonique d'alcane, puis on sépare la phase solide ainsi obtenue, on élimine par distillation l'excédent d'HCl contenu dans la phase liquide isolée, le cas échéant avec une partie de l'eau, et on récupère les acides sulfoniques d'alcane pratiquement dépourvus de chlorure avec l'eau résiduelle dans la phase résiduelle de la distillation. Ce procédé permet ainsi d'obtenir des acides sulfoniques d'alcane pratiquement dépourvus d'ions de chlorure.

Abstract: Procédé de production de microfilaments de très faible diamètre pour des fils synthétiques ou des nappes de monofils continus, selon lequel les microfilaments sont extraits et étirés, sous grande vitesse d'extraction, à travers un trou de filage, à partir de filières alimentées avec une matière en fusion. Il est prévu d'exposer les microfilaments, immédiatement après leur sortie du trou de filage, à un courant d'air chaud entourant le microfilament à la manière d'une enveloppe. On obtient ainsi un refroidissement en continu des microfilaments, de sorte qu'en dépit d'une vitesse d'extraction élevée, on évite des cassures de filaments et qu'en outre , les vitesses d'extraction du dispositif de filage peuvent être maintenues, même à de très faibles diamètres.

Abstract: The invention relates to a container with side walls, base and lid covers and with a tip which can be bent over about a folded edge to create a pouring opening. When bent over, the tip (7) is positioned with its surface on the container wall (6) adjacent to the folded edge (13). The container should be designed in such a way that its closure can be opened without the use of a tool, i.e. especially without using scissors, and subsequently closed again. The tip (7) exhibits a nozzle-shaped element (11) which projects from its surface which is adjacent to the folded edge (13) to form the pouring opening. The container wall (6) has a recess (12) into which the nozzle-shaped element (11) fits in the closed position.

Abstract: The transporting, namely lifting up, conveying and setting down, of cardboard boxes (10) and the like is made possible in the packaging industry by the use of palletisers (23). On an articulated arm (24) is a gripper (27) with upright supporting arms (29, 30) which carry supporting limbs (31, 32) for grasping the underside of the cardboard box (10). The supporting limbs can be swung out of a horizontal supporting position into an essentially vertical release position. The latter position permits problem-free lifting of the gripper after a cardboard box has been set down, even when working in confined spaces. The supporting arms (29, 30) of the gripper (27) can in turn be swung out of an essentially upright position into a spreading oblique position to allow cardboard boxes to be grasped when the supporting limbs (31, 32) are horizontal. <IMAGE>

Abstract: The present invention relates to a method for processing a video signal coded in the form of blocks of k words, this signal being written to or read from two frame memories (FM1, FM2) each comprising an input port, a high-speed output port and a low-speed output port. According to this method, the digital video signal at the input is formed of sets of M' blocks with N' blocks containing luminance data (Y1, Y2,...) and M'-N' blocks containing chrominance data (C1, C2,...), the blocks containing the chrominance data (C1) being written into the first memory (FM1) and the blocks containing the luminance data (Y1) being written into the second memory (FM2), the memories being reversed with each frame. Next, the blocks containing the luminance data and the blocks containing the chrominance data are read simultaneously on the high-speed output port of each memory, the memories being reversed with each frame, and the data are optionally processed so as to obtain at the output video data exhibiting a compression ratio of M/N with M > N.

Un ou plusieurs points d'intérêts se trouvant sur le bloc image du système vidéo de surveillance sont identifiés conjointement avec un point prédéterminé de la ligne de base obtenus à partir d'une vue en images de la ligne de base se superposant sur le bloc image du système vidéo de surveillance. Cette phase d'identification est effectuée manuellement par l'opérateur qui actionne un bloc de touches à effleurement (56) ayant des lignes quadrillées fines qui correspondent aux points des pixels dans l'image du bloc image vidéo. La distance entre deux points identifiés est calculée sur la base de l'échelle de l'image vidéo et des données relatives à la position de la caméra.
