Patent EP-0402187-A1 (EP)
Inventor: VILLAIN CLAUDE
IPC: A61B18/20
Filed: 1990-05-15
Abstract: An optical arm for guiding a laser beam consists of a succession of tubes (3, 4, 5) coupled to each other by anti-friction bearings (18, 19), the beam being propagated in the tubes; several axial reflecting mirrors (11, 12) each placed at the entrance of one of the tubes; a component (1) at the input end through which the laser beam enters the system, mounted on the output of a device for generating a laser beam in such a way that it can be detached; and a component (2) at the end of the system where the laser beam leaves it, adapted so that it cooperates with a manual device for the application of the laser beam. The optical arm incorporates a device (29; 47) for braking the rotational motion, operating on the first two coupled tubes (3, 4) near the end at which the beam enters, and a balancing system (34) mounted on the second coupled tube (4) from the said input end. <IMAGE>

Abstract: There is provided a process for preparing a sub-soluble and splittable, conjugated microfiber with a cross section having matrix orange islands and slightly connected with each other at the tip of the orange island in the matrix center. Conjugated fibers can be made into filaments and staple fibers. Filaments are spinning taken-up and then is carried out texturing by means of a belt nip twister and the resulting texture yarns are sub-dissolved following weaving to split. As to the staple fibers, it is staple fiber processed to obtain staple fibers and followed by processing into non-wovens or spinning to spun yarn and then weaving. Owing to a different splitting method from filament fabrics, staple fibers can be made to fabrics as follows:
     1. Suede fabrics;   2. Water resistant and humid permeable, high density fabrics;   3. Peachskin fabrics.

Abstract: L'invention consiste à éviter des phénomènes de résonance dans un réseau d'impédance inconnue pendant le fonctionnement d'un convertisseur. Par exemple, dans le cas d'une locomotive alimentée par convertisseur, pour éviter la formation dans le réseau d'ondes verticales se modifiant de façon incontrôlée pendant la marche de la locomotive, une fonction caractéristique de transmission (par exemple, l'impédance d'entrée du réseau) est identifiée d'abord de façon permanente par mesurage électrique et transformation de Fourier et simulée au moins dans le domaine de son maximum par un réseau virtuel de circuits oscillants discrets. Les variables d'état du modèle de réseau, par exemple les courants passant suivant le cas dans les circuits oscillants, peuvent être calculées à partir des paramètres réseau identifiés sous forme de fonction de l'instant de commutation du convertisseur. On peut calculer une impulsion-type optimale pour le fonctionnement du convertisseur, au moyen de la variation virtuelle des instants de commutation, impulsion ne causant aucune résonance dans le réseau réel.

Abstract: Une pompe comporte une pluralité de soufflets (51 à 54) groupés en étoile autour de l'axe d'entraînement et entraînés simultanément de sorte que le couple est appliqué uniformément. Le chargement asymétrique des soufflets, lequel réduit leur durée de vie, est évité grâce à un couplage amélioré du mouvement excentrique de l'arbre d'entraînement (34) avec les soufflets. Les sorties (62) des différents soufflets peuvent être reliées en parallèle ou en série, au choix, de manière à permettre un refoulement ou une pression de refoulement accrus, selon les besoins. Le carter de pompe (1) se compose d'une pièce en double croix servant de pièce de montage dans la technique de l'ultravide. Pour réaliser le vide complet dans la pompe, par exemple pour permettre l'introduction ultérieure de gaz ultra-purs, des soupapes à ressort (82) qui s'opposent au sens de refoulement sont maintenues temporairement en position ouverte, en service normal. A cet effet, les éléments de fermeture des soupapes sont réalisés dans un matériau magnétique et peuvent subir l'influence d'un aimant (84) monté à l'extérieur du carter de pompe (1, 73), lequel est réalisé dans un matériau non magnétique. La soupape reprend sa position fermée, dès que l'aimant (84) est amené et éventuellement arrêté dans une position éloignée.

Abstract: L'invention propose un nouveau procédé de séparation et un dispositif correspondant ainsi que l'utilisation du dispositif pour la séparation de différents mélanges de substances dans des conditions de respect de l'environnement, utilisant, outre des forces dynamiques, en particulier la pression superficielle entre les corps à trier, un tambour (2) déformable vers l'intérieur. Les corps à forte pression superficielle (6) tombent à l'intérieur du tambour (2) et sont éjectés vers le bas. En revanche, les éléments à faible pression superficielle (8, 9) sont écartés de la surface du tambour (2) et rejetés séparément. Pour la première fois, il est ainsi possible, avec des moyens extrêmement simples, d'obtenir une séparation de très bonne qualité, même avec des corps pour lesquels jusqu'à présent seule une séparation manuelle était économique. La nouvelle invention est particulièrement efficace pour la séparation des mélanges de matières valables, dites recyclables, surtout lorsqu'il s'agit de fractions qui sans cela seraient difficiles à séparer, comme les produits recueillis dans les bennes à ordures.

Abstract: A filter for removing impurities from waste gases, and especially from the waste gases of an internal combustion engine, includes a filter body consisting of a plurality of compression moulded, high temperature resistant, sintered filter plates consisting of metal powder, metal chips, metallic fibres or a mixture of these materials, which are arranged on top of or behind one another and kept at a distance from one another by spacers, to form between them a plurality of flow channels. The flow channels are open at one end and closed at the other end in order to form inlet and outlet channels. The walls of the filter plate situated between the inlet and outlet channels constitute filter surfaces. The filter plates are formed by filter discs lying on top of one another, arranged in a filter housing and having a free or open central interior space, so that the waste gases flow radially through the filter discs from the outside towards the interior space or from the interior space towards the outside.

Abstract: The invention provides a molten metal producing and refining method which does not damage the apparatus, realizes a stable and high second combustion rate, and is capable of effectively recovering heat generated by the second combustion. It is a molten metal producing and refining method wherein a metal-containing material, a carbonaceous material, a flux and O<6> gas are introduced into a furnace, the carbon dissolving into the metal bath in the furnace from the carbonaceous material is combusted with the O<6> gas to generate heat and CO gas, the CO gas is subjected to the second combustion with the O<6> gas to additionally generate heat, and the metal-containing material is melted and refined by both the generated heat and carbon, said method being characterized in that O<6> gas or O<6>-containing gas is blown into the furnace through large-diameter tuyeres installed near the bottom of the furnace and a part of the O<6> gas does not combust in the metal bath and leaves the metal bath unburnt, to perform the second combustion of the unburnt O<6> gas with CO gas in the slag bath in the furnace. <IMAGE>
