Title: Multiplexeur et demultiplexeur pour liaisons de communication a fibres optiques monomodes
Inventor: BOORD WARREN TIMOTHY
IPC: H04B10/2507
Filed: 1999-02-10
Abstract: L'invention concerne un multiplexeur et démultiplexeur optique destiné aux systèmes de communication par fibres optiques à multiplexage par répartition en longueurs d'ondes à canaux denses (DWDM). En tant que multiplexeur, le dispositif combine spatialement les signaux optiques provenant de plusieurs sources laser (dont chacune a une longueur d'onde différente) et injecte les faisceaux laser spatialement combinés dans une seule fibre optique. En tant que démultiplexeur, le dispositif sépare spatialement les différentes longueurs d'onde d'une liaison optique multiplexée par répartition des longueurs d'ondes et injecte chacune desdites longueurs d'onde dans une fibre optique différente. Dans les deux modes de réalisation, le dispositif comprend des composants optiques massifs et des composants optiques intégrés. La séparation ou la combinaison spatiale des faisceaux laser de différente longueur d'onde s'obtient au moyen de réseaux de diffraction massifs. Les composants optiques massifs sont également utilisés pour collimater et former les faisceaux laser se propageant dans l'espace libre, ce qui permet de coupler efficacement la lumière dans les fibres optiques monomodes, ou les guides d'ondes optiques intégrés, et diminue la diaphonie optique. Des diviseurs de faisceau polarisants orientent la polarisation de la lumière, de façon à optimiser l'efficacité de la diffraction par les réseaux et à diminuer la perte due à la polarisation. En outre, les faces terminales des fibres optiques et des guides d'ondes intégrés ont subi un polissage d'angle, ce qui diminue l'écho de fond et ainsi le bruit dû au retour à la source laser. De préférence, le réseau de diffraction et l'optique de focalisation sont spécifiées de façon à permettre le multiplexage et le démultiplexage de longueurs d'onde laser séparées de 0,4 nanomètres (nm) dans la bande de longueur d'onde de 1550 nm. Le champ de vision préféré de l'optique permet de multiplexer et de démultiplexer jusqu'à 32 canaux de longueur d'onde séparés de 0,4 nanomètres dans la bande de longueur d'onde de 1550 nm. Les exemples de performances sont donnés pour la bande de longueur d'onde de 1550 nm, mais les composants du dispositif peuvent être conçus pour une utilisation dans d'autres bandes, telles que la bande à faible affaiblissement par absorption à .lambda. ?1310 nm des fibres optiques.

Abstract: A method and device effect controlled uniform temperature drying of a wet web, such as a paper web substantially immediately after formation in a paper machine, without damaging the supporting fabric carrying the web. The web has a central region and first and second border regions. The wet web to be dried is conveyed on a conventional supporting fabric/wire in a first direction generally parallel to the web border regions, and in a hood drying air is blown against the web from the opposite side thereof as the supporting fabric so that the drying air picks up moisture and becomes moistened air. The moistened air is discharged from the volume adjacent the hood, for example is discharged from at least one hood positioned at and encompassing an impingement surface over which the web and supporting fabric pass. Air supplied for blowing against the web is heated to raise its ability to retain moisture. Drying air with a first temperature and first velocity is directed against a central region of the web, and drying air with a second temperature, lower than the first temperature, and second velocity, higher than the first velocity, is directed against the web in the border regions.  The hood may be divided into at least one central block and first and second border blocks, corresponding to the central region and first and second border regions of the web. A first plurality of air nozzles may be disposed within the hood central block, and second and third plurality of air nozzles disposed in the hood first and second border blocks, with a different fan and heater supplying air to each of the plurality of air nozzles.

Title: Controle chimique de la porosite d'une ceramique au moyen de carboxylate-alumoxanes
Inventor: CALLENDER RHONDA LYNN
IPC: C01F7/02
Filed: 1999-03-26
Abstract: L'invention concerne en général un procédé servant à contrôler la dimension des pores, la répartition de cette dimension et la porosité de céramiques à base d'oxyde d'aluminium et consistant à sélectionner des substituants de carboxylate-alumoxanes et de nanoparticules d'oxyde d'aluminium. Ce procédé permet d'obtenir des pores intragranulaires de l'ordre du nanomètre à créer dans des corps de céramique d'alumine et d'oxyde d'aluminium. On effectue le contrôle de la dimension des pores et de la répartition de cette dimension par l'intermédiaire de différents substituants chimiques des carboxylate-alumoxanes et des nanoparticules d'oxyde d'aluminium. La dimension et la répartition des pores à l'intérieur de la céramique d'oxyde d'aluminium dépend de l'identité des substituants de carboxylate. En particulier, la formation d'une porosité intragranulaire par rapport à une porosité intergranulaire dépend de l'identité des substituants de carboxylate. L'invention concerne également des procédés servant à fabriquer des revêtements de céramique sur des fibres de céramique et de carbone pour des mises en application composites et des membranes de céramique présentant des dimensions de pores de l'ordre du nanomètre. On contrôle la dimension des pores, la répartition de la dimension des spores, la porosité et, de ce fait, la résistance, la perméabilité et l'adhérence de surface du revêtement de céramique au moyen du choix du substituant de carboxylate-alumoxane. La thermolyse de couches centrifugées autonomes de ces carboxylate-alumoxanes permet d'obtenir des disques d'alumine dont la dimension de pores, la répartition de cette dimension et la porosité ont été contrôlées. Dans un autre mode de réalisation, on trempe un substrat poreux dans une solution de carboxylate-alumoxane ou on le revêt de cette solution, puis on le soumet à une thermolyse afin d'obtenir une membrane composite.

IPC: G06F17/30
Filed: 1999-09-03
Abstract: A method and apparatus are provided for handling within a database system data items that are associated with data types whose native structure is not known to the database system. The data items are stored within the database system in their native structure, even though it is not understood by the database system. To store the data items, the database system calls a pickling routine that is provided by the user, or by the runtime subsystem of the programming environment that is native to the data item. To retrieve the routine from storage, the database system calls an unpickling routine, also provided by the user or the appropriate runtime subsystem. Because the database maintains the data items in their native format, no conversions are required as the data items are passed between the database system and external routines that manipulate the data items. Techniques are also provided for declaring attributes of the data item that can be accessed within the database system. The user provides routines for the database system to call in order to access the declared attributes, which may be different than the actual attributes that the data item has in its native environment.
