Patent CA-2248072-A1 (CA)
Inventor: DINGSOR ANDREW D
IPC: H04B1/40
Filed: 1997-05-05
Abstract: Procédé, dispositif et article servant à corriger les erreurs de fréquences de porteuse. Un signal de modulation de fréquence est reçu par une antenne et transmis à un récepteur. Ce récepteur admet le signal de modulation de fréquence à la fréquence de porteuse et émet un signal de bande de base. Ce signal de bande de base est ensuite traité par un processeur de signaux numériques effectuant la correction et le décodage de la fréquence de porteuse afin de produire un flux de données qu'un microprocesseur transmet à un ordinateur central. Les différences entre la fréquence de porteuse de modulation de fréquence et la fréquence utilisée pour démoduler le signal de modulation de fréquence peuvent déplacer le niveau de polarisation de courant continu du signal de bande de base. Le processeur de signaux numériques corrige cette différence de fréquence au moyen d'une valeur de correction de réception appliquée ensuite à chaque échantillon de signal reçu. La transmission des données s'effectue depuis l'ordinateur central vers le processeur de signaux numériques par l'intermédiaire d'un microprocesseur. Le processeur de signaux numériques effectue le codage et la correction de fréquence de porteuse des données afin de fournir un signal de bande de base à un émetteur qui module ce signal de bande de base afin de produire un signal de modulation de fréquence à la fréquence de porteuse souhaitée. Les différences de fréquence entre la fréquence souhaitée de modulation de fréquence et la fréquence utilisée afin de moduler le signal de bande de base peuvent produire des erreurs dans les systèmes récepteurs. Le processeur de signaux numériques corrige cette différence de fréquence au moyen d'une valeur de correction d'émission qu'il applique ensuite à chaque échantillon de signal codé.

Patent CA-2254970-A1 (CA)
Inventor: TENNENT HOWARD
IPC: C01B31/02
Filed: 1997-05-15
Abstract: This invention relates to rigid porous carbon structures and to methods of making same. The rigid porous structures have a high surface area which are substantially free of micropores. Methods for improving the rigidity of the carbon structures include causing the nanofibers to form bonds or become glued with other nanofibers at the fiber intersections. The bonding can be induced by chemical modification of the surface of the nanofibers to promote bonding, by adding "gluing" agents and/or by pyrolyzing the nanofibers to cause fusion or bonding at the interconnect points.

Title: Photo-addressable substrates and photo-addressable side-group polymers with highly inducible double refraction
Inventor: KOSTROMINE SERGUEI
IPC: G11B7/2533
Filed: 1997-05-15
Abstract: It is possible to produce extremely rapidly photo-addressable storage media from inherently slowly photo-addressable polymers by irradiating the substrates over a large area with a light source suitable for conventional inscription so that an optical anisotropy, i.e. a double refraction with a preferential direction in the plane of the substrate, occurs. If the substrates prepared in this way are briefly intensively irradiated, the pattern is inscribed extremely rapidly and permanently. The invention also relates to novel side-chain polymers in which high optical anisotropy can be generated by irradiation. This optical anisotropy is very heat stable.

Title: Method for carbon dioxide recovery from a feed stream
Inventor: LANG GARY
IPC: C01B32/50
Filed: 1999-04-30
Abstract: The method of the invention recovers CO2 from an inlet cold feed stream containing a low concentration thereof, and includes the following steps. An inlet feed stream is passed through a heat exchanger, against a compressed flow of the inlet feed stream, to cool the compressed flow. The compressed flow is further cooled and compressed to a high pressure, fed to a distillation column and there converted into a vent gas including CO2 and a high purity bottom liquid CO2. A first portion of the bottom liquid CO2 is expanded to achieve a first cooled liquid CO2 refrigerant flow, which is then vaporized against the vent gas to recover condensed CO2 therefrom. The condensed CO2 is then reintroduced into the distillation column. A second portion of the bottom liquid CO2 is expanded to achieve a second cooled liquid CO2 refrigerant flow, which is then used to subcool the CO2 product output.

IPC: G06F13/14
Filed: 1999-06-29
Abstract: One embodiment of the present invention provides a method and an apparatus for verifying configuration of storage devices in a computer system based upon device identifiers within the storage devices. The method and apparatus provide a computer system that reads device identifiers from storage devices in the computer system, and uses the device identifiers to create a mapping associating the device identifiers with corresponding physical paths to the storage devices. Upon reconfiguration of the storage devices, the computer system again reads device identifiers from storage devices in order to verify that the system was reconfigured correctly. In a variation on this embodiment, the computer system additionally associates a logical path with each storage device. When the computer system subsequently receives an access request for the storage device directed to the logical path, the computer system translates the logical path into an associated physical path, and uses the physical path to access the storage device.

Abstract: A water filter device has a collecting pot (1) with a spout (2) disposed at the front, with a handle (3) disposed at the rear in opposite relationship, and with an electrical heating element (5) arranged in the lower boiling region of the collecting pot (1), in this arrangement the collecting pot (1) is closable at the top by a lid (4) and provided in the interior is a filter insert (8) in which a filter cartridge (9) which can be filled with a purification agent is arranged so that untreated water can be poured into the filter insert (8) by way of the filter cartridge (9) and can pass due to the force of gravity to at least under the filter cartridge (9). The filter insert (8) is arranged in an insulating insert (6) in such a way that provided between the boiling region at the bottom in the collecting pot (1) and the filter insert (8) with the filter cartridge (9) is a partition wall (10, 10a) which is generally arranged at a spacing from the filter insert (8) and which is at least partially in the form of a horizontally extending plate. Provided in the lower region of the insulating insert (6) is a through opening (7) for the connection between the discharge end of the cartridge (9) and the collecting pot (1).      So that such a water filter device can be simplified to the effect that the filter insert (8) can be removed separately from the insulating insert (6), in which case the inserts (6, 8) can be better cleaned, the pouring properties of the pot are improved and operation of the device can be better adapted to different amounts of water to be purified, it is provided in accordance with the invention that the through opening (7) is arranged in the rear region (D) of the collecting pot (1) which is in opposite relationship to the spout (2), the substantially horizontally extending part (10a) of the partition wall (10) is inclined rearwardly relative to the through opening (7) and extends above the boiling region at least partially over the cross-section of the collecting pot (1).
Patent CA-2286547-A1 (CA)
Title: Resin applicator
Inventor: KENNEDY MATTHEW GORDON CHARLES
IPC: B05C17/005
Filed: 1999-10-20
Abstract: The invention is an applicator and process used to fill in the edges of composite panels with resin or emulsions. The applicator is attached to a pressurized canister filled with resin that forces the resin through the applicator's channel, into a space between the applicator's spatula and the panel's edge. The sidewalls of the applicator guide the applicator along the edge of the panel as it is drawn along to fill the edge and also to prevent spill over. The aft-end of the applicator body is a spatula that tapers toward the panel's edge and acts to smooth the resin flush with the panel's sidewalls. A finger guide allows the applicator to work using finger pressure. The applicator is drawn along with the hands, and where the leading edge of the applicator body rests on the panel there is a rounded lip to allow the applicator to traverse smoothly over roughness and imperfections on the panel's edge. The rounded lip feature also functions as a pivot that allows the applicator to be pivoted in such a way that the sidewalls will rise above the panel's edge so that the applicator can clear obstacles like adjoining panels without having to be removed from the panel being filled. Ribbing on the underside of the spatula facilitates the flow of resin over the entire edge of the panel. The applicator may be fashioned to accommodate varying panel thickness or edge profile, such as straight, angled, or bullnosed. The applicator may also be used to apply adhesives to the edges of solid panels.      The invention can alternatively be fashioned for automation.

IPC: H04B10/291
Filed: 1999-11-16
Abstract: In a duplex WDM transmission system, an optical amplifier that uses different amplification paths for amplification of the different directions of signal propagation requires filters to keep the loop gain less than unity for all wavelengths within the amplification waveband. Simple high-pass and low-pass filters can be used when red channels are used for signals propagating in one direction, and blue ones for those propagating in the other. Comb filters are, however, required for use in any optical amplifier employed such a transmission system using any form of interleaved form of channel allocation in place of the red/blue allocation. Examples of such amplifiers are described, these amplifiers having filters possessing an arrayed waveguide grating structure.
