Title: Apparatus for the selective removal of chemical species from a fluid.
Inventor: BATTS GREGORY NIGEL
IPC: G01N30/60
Filed: 1991-08-06
Abstract: Apparatus for the selective removal of a chemical species from a fluid comprises a housing defining a chamber, the housing having fluid inlet and outlet means, the chamber containing an impervious sheet or sheets arranged in layers wherein the layers are spaced apart from each other by spacer means, the layers being positioned relative to the inlet and the outlet to define a fluid flow path such that, when the apparatus is in use, fluid entering the chamber through the inlet passes between the layers before leaving the chamber through the outlet. The space between the layers is partially filled with particulate material capable of selectively removing a chemical species from a fluid, the particulate material being retained between the layers.

Title: Procede pour la recuperation de l'huile contenue dans des boues d'huile usee
Inventor: HEUER STEVEN RAY
IPC: C10M175/00
Filed: 1991-08-09
Abstract: De l'huile ayant une valeur commerciale est récupérée de boues d'huile usée qui résultent du raffinage et qui sont considérées comme dangereuses par le "Resource Conservation and Recovery Act" au moyen d'une série d'étapes de volatilisation et de condensation (qui peuvent être différentes selon la teneur en huile, en eau et en solides de la boue). Ce procédé permet de produire de l'eau et des sous-produits solides de récupération non dangereux. Une boue pouvant être pompée, ayant un faible indice de viscosité, une forte teneur en huile et/ou en eau est tout d'abord centrifugée dans une centrifugeuse (14) pour séparer l'huile et l'eau libres. Si les boues résiduaires sont acides ou si du nickel se trouve dans les boues en quantité suffisante pour que les filtrats résiduaires atteignent des niveaux inacceptables selon les prescriptions TCLP de l'EPA fédérale, une base (telle que de l'oxyde de calcium) est ajoutée au moyen d'une conduite (12), dans l'unité (19) à la boue d'huile usée épaisse, aux solides centifugés, ou à d'autres boues à faible teneur en huile et/ou en eau pour rendre ces boues basiques. Les boues mélangées basiques sont chauffées pour volatiliser l'eau et l'huile qu'elles contiennent dans un appareil d'évaporation huile-eau (23). Les solides déshuilés, friables et secs sont recyclés par l'intermédiaire d'une conduite (26a) avec des boues huileuses d'alimentation pour éviter une agglomération des matières et un encrassement de l'échangeur de chaleur. La vapeur d'huile et d'eau provenant des appareils de volatilisation à haute température (24a-24z) est recyclée et utilisée comme source de chaleur indirecte pour l'appareil de volatilisation à basse température (23). L'huile et l'eau volatilisée sont condensées dans un condenseur (30) et mélangées avec l'huile et l'eau résultant de la centrifugation, l'huile et l'eau étant essentiellement séparées par gravitation. L'huile est séparée de toute eau et de tout solide résiduaire. L'eau résiduaire non dangereuse, presque exempte d'huile, et les solides

Abstract: Châssis (2) d'abat-jour pliant comprenant: un membre de support supérieur (4) et un membre de support inférieur (6) espacés l'un de l'autre et se trouvant dans des plans parallèles; plusieurs éléments de châssis périphériques (8), s'étendant entre les membres de support (4 et 6), chaque élément de châssis (8) ayant l'une de ses extrémités (10) reliée pivotante au membre de support supérieur (4) et l'autre extrémité (12) fixée au membre de support inférieur (6) et étant pourvu d'une articulation située entre les deux extrémités. Le châssis comporte également un élément intermédiaire en araignée (14) comprenant un cercle central (16) ainsi que plusieurs branches (18) s'étendant en rayon autour du cercle, l'une des extrémité de chaque branche (18) étant fixée au cercle (16), tandis que l'autre extrémité (20) est montée pivotante sur une coulisse (22) montée sur l'un des éléments de châssis (8). L'élément en araignée (14) est mobile dans une direction sensiblement perpendiculaire aux membres de support (4 et 6), déplacement qui modifie l'état du châssis (2) en le faisant passer d'un état stabilisé, dans lequel aucun mouvement des éléments de châssis (8) n'est possible autour des articulations, à un état permettant pliage, état dans lequel chaque élément de châssis (8) peut pivoter librement vers l'intérieur ou vers l'extérieur autour de son articulation respective de manière à rapprocher les deux membres de support (4 et 6) et à plier le châssis (2). En effectuant un mouvement inverse, on éloigne les deux membres de support (4 et 6) l'un de l'autre, redressant ainsi le châssis (2).

Abstract: Annuleur d'écho (15) permettant de réduire le retour acoustique entre un haut-parleur (32) et un microphone (10) dans un système de communication en duplex intégral. Un filtre de blanchiment (14) égalise le spectre du signal du microphone et réduit son autocorrélation. Un diviseur de signal (16) divise le signal du microphone à bruit blanc en plusieurs signaux de microphone à largeur de bande limitée. De même, le signal du haut-parleur est blanchi et divisé en plusieurs signaux de haut-parleur à largeur de bande limitée, par un diviseur de signal (30). Chacun d'une pluralité d'annuleurs d'écho (18) génère un signal d'estimation d'écho représentant une approximation du retour acoustique d'un signal correspondant de haut-parleur à largeur de bande limitée, dans le microphone. L'annuleur d'écho (18) élimine chaque signal d'estimation d'écho contenu dans le signal de microphone à largeur de bande limitée et ayant la même bande de fréquence que celle du signal d'estimation. Des écrêteurs centraux (20) éliminent tout écho résiduel dans chaque signal dont l'écho a été corrigé. Des bruits de remplissage (22) simulent les signaux de bruit de fond éliminés par les écrêteurs (20).

Abstract: High torque brushless motors are proposed which have low weight and high efficiency. The permanent magnet rotor has many equally spaced poles of alternating polarity. The stator has a plurality of pole groups, each pole group have a plurality of poles with the same pitch as the rotor poles. Windings (211 - 216, 221 - 226, 231 - 236, 241 - 246, 251 - 256, 261 - 266) connected to electrical phases (R, S, T) are provided on the poles within each pole group to polarize the poles in the group with alternating polarity. The pole groups are displaced relative to each other and the gaps between the pole groups is filled by flux balancing poles (217, 227, 237, 247, 257, 267) which in many cases are unwound. The motor may be driven by means of an inverter and by providing it with at least two winding sections of each phase, configuration switches to connect the winding sections in at least one serial and one quasi-parallel configuration and at least twice as many bridgelegs (twice as many inverter switching elements) as would otherwise be required as a minimum in the selected bridge configuration it can be driven at two different torques. <IMAGE>
