Abstract: L'invention concerne un procédé de surveillance et d'analyse de procédé de fabrication de papier, qui comporte les étapes consistant à : mesurer un grand nombre de quantités (x¿i?, t) du processus ; introduire ces quantités mesurées (x¿i?, t) comme vecteur d'entrée (X, t) dans un réseau neuronal, qui, en réponse au vecteur d'entrée, produit un vecteur de sortie (Y, t) comme quantité continue ; déterminer et stocker en mémoire au moins une empreinte compatible avec une bonne situation de processus du point de vue de la possibilité d'exécution, c.-à-d. un vecteur de sortie optimal (Y¿o?, t) ; comparer sensiblement en temps réel les empreintes stockées et les empreintes ou vecteurs de sortie obtenu(e)s dans une situation normale de processus ; déterminer, sur la base de cette comparaison, une différence à présenter sous forme graphique à l'utilisateur. Selon l'invention, on détermine une quantité k=k(t) scalaire continue dépendant du temps, destinée à être présentée à l'utilisateur, comme distance géométrique entre l'empreinte mesurée instantanée (Y, t) et l'empreinte optimale (Y¿o?), et cette quantité scalaire k=k(t) est présentée à l'utilisateur par l'intermédiaire d'un écran.

Title: Sealing apparatus having sequentially engageable seals
Inventor: RAMSAY THOMAS WILSON
IPC: F16J15/00
Filed: 2001-04-13
Granted: 2007-07-24
Abstract: Advantageous seal systems (1500) are provided that include a barrier member movable relative (1504) to a shaft (1550) to allow sequential engagement of resilient seal members (1506), e.g. , lip seals, with the shaft. Movement of the barrier member (1504) may be effected manually or through introduction of pressurize d fluid to effect piston-like movement. The disclosed seal assemblies may include an automatic leak detector and may utilize such leak detection to effectuate automatic movement of the barrier member. The barrier member may be moved relative to the shaft while the shaft is in movement, e.g., rotating or re-ciprocating, thereby permitting seal maintenance without interruption in operation. As seal members are sequentially brought into sealing engagement with the shaft, the previously engaged seal members contribute to the sealing performance of the seal assembly, although no longer effective to establish a stand-alone seal with the shaft.

Title: Procede permettant de produire des structures a l'aide de forces centrifuges
Inventor: DALTON PAUL D
IPC: B29C39/08
Filed: 2001-05-11
Granted: 2009-07-28
Abstract: L'invention concerne une variété de structures creuses présentant des morphologies uniques, fabriquées à l'aide de techniques de centrifugation par rotation. Selon le procédé décrit dans cette invention, la séparation de phases des solutions solubles s'effectue à l'intérieur d'un moule rempli pendant la rotation de ce dernier autour de l'un de ses axes. Au fur et à mesure que la séparation de phases s'effectue dans le moule en rotation et à l'application de force centrifuges, l'augmentation de la densité de l'une des phases permet d'obtenir un sédiment à la périphérie. Après ou pendant la sédimentation, la gélification des particules à séparation de phases se fixe sur la morphologie du tube et le solvant reste au centre du moule. Le solvant est retiré du moule formant ainsi un tube. La possibilité de commander la vitesse de rotation, et la chimie de préparation permettent de manipuler les dimensions du tube et la morphologie de la paroi. Cette technique permet une nouvelle approche de la fabrication des tubes polymères. Elle nécessite une quantité faible de produit de départ, elle permet d'obtenir une structure de tubes multicouches, elle peut être appliquée à divers polymères et elle peut permettre d'obtenir des structures creuses diffusantes tout en maintenant une bonne résistance mécanique.

Title: Five-port topology for direct down-conversion
Inventor: RATNI MOHAMED
IPC: H04B17/40
Filed: 2003-01-17
Granted: 2006-04-04
Abstract: The underlying invention generally relates to the field of five-port receivers, especially to a new topology for a five-port junction device (11) with three power sensors (PD1, PD2 and PD3) to be applied to the processing and direct down-conversion of broadband RF signals within an operation band-width between 1 and 7 GHz. Thereby, said receiver does not need any additional passive (resistive) network, which leads to a significant increase in the overall signal-to-noise (S/N) performance. Compared to receivers with a resistive five-port topology according to the state of the art, a non-optimized structure sensitivity enhancement (system gain) of 8-9 dB can be observed. Since a simpler technology is em-ployed, a significant decrease in microchip side (of more than 50 %) can be achieved.      The key issue of the proposed solution is to connect power detectors (PD1, PD2 and PD3) in a II-type network topology, and to attach resistive and/or reactive components - e.g. a combination of two or more parallel and/or series-connected resistors (R), capacitors (C) and/or inductors (L) or a transmission line (1a) of a specific length, which is usually placed outside of the microchip (10) - between two connection nodes (A and B). The actual matching of the power detectors (PD1, PD2 and PD3) does not play an important role due to the calibration procedure, Thus, the main issue is how to get the highest possible power with minimum losses to the detector sources (PD1, PD2 and PD3) while approving the same method of phase shifting as conventional solutions.

Abstract: High availability for a fibre channel switch in a storage area network can be implemented using redundant supervisors. An active supervisor can identify high availability characteristics associated with a message and determine whether the message should be mirrored onto a redundant supervisor, logged, and/or made persistent. Messages can be logged in a pending transaction buffer and stored using persistent storage services. Mirroring can be performed using synchronization queues that allow messages to be passed asynchronously to a redundant supervisor while maintaining full synchronization between supervisors and causing little delay to operation of the active supervisor.
