Patent CA-2304046-A1 (CA)
Inventor: VITERI FERMIN
IPC: F25J3/04
Filed: 1997-09-22
Abstract: A low pollution engine (500) is provided for delivering power for vehicles.  The engine has an air inlet (510) which collects air from a surrounding environment. A portion of the nitrogen in the air is removed using a technique such as liquefaction, pressure swing adsorption or membrane based air separation. The remaining air is primarily oxygen, which is then compressed and routed to a combustion chamber. The chamber has an igniter and inputs for the pressurized oxygen and pressurized hydrogen containing fuel, including methane.  The combustion products of water and carbon dioxide are expanded through a power generating device, such as a turbine or piston expander (560). The combustion products are then passed through a condenser (580) where the steam is condensed and the carbon dioxide is collected or discharged. A portion of the water is then routed back to the gas generator.

Title: Nanocomposites a interfaces activees prepares par broyage mecanique d'hydrures de magnesium et usage de ceux-ci pour le stockage d'hydrogene
Inventor: SCHULZ ROBERT
IPC: H01M8/06
Filed: 1998-10-21
Abstract: L'invention vise un procédé de préparation d'un nanocomposite à base de magnésium et d'un autre élément ou composé connu pour absorber l'hydrogène et être peu miscible au broyage avec le magnésium ou son hydrure, tel le vanadium, le titane ou le nobium. Selon ce procédé, on soumet le magnésium ou un composé à base de magnésium connu pour absorber l'hydrogène à une hydrogénation en vue d'obtenir l'hydrure correspondant sous la forme d'une poudre. On mélange alors la poudre d'hydrure ainsi obtenue avec l'autre élément ou composé ou un hydrure de cet autre élément ou composé et on soumet le mélange ainsi obtenu à un broyage mécanique intense jusqu'à obtention du nanocomposite correspondant sous la forme d'un hydrure.  Enfin, si requis, on soumet le nanocomposite ainsi obtenu à une désorption d'hydrogène. L'invention vise aussi le nanocomposite à base de Mg ainsi préparé, qui a l'avantage d'être peu coûteux et d'avoir des performances inégalées pour le stockage de l'hydrogène grâce à sa microstructure (c'est-à-dire à la nature des interfaces et à la distribution spatiale de ses composantes) qui est extrêmement fine et donne lieu à un effet de synergie incroyable entre le Mg et l'autre élément ou composé.

Abstract: La présente invention concerne des procédés et un appareil qui détectent de manière améliorée la rotation non uniforme sans utiliser de repères susceptibles de créer des ombres sur les tissus situés derrière les repères ou d'autres éléments indésirables dans l'image. Dans des exécutions spécifiques, la présente invention fournit une solution utile et particulièrement simple au problème de la déformation due à une rotation non uniforme de l'image échographique intravasculaire dans les systèmes à balayage mécanique. Dans lesdites exécutions, la présente invention utilise la corrélation de signaux reçus, par la réverbération d'ultrasons dans un cathéter (13) rempli de liquide bulleux et le vecteur d'imagerie en découlant pour déterminer la rotation non uniforme du transducteur (22) dans ce cathéter (13). En d'autres termes, la présente invention recourt à la corrélation de vecteurs d'imagerie dans une zone de taches de sang, en utilisant une largeur donnée du faisceau d'ultrasons d'un transducteur (22) pour déterminer la rotation non uniforme de ce transducteur (22).

Title: Method for optimizing mobile wireless communications routed across plural interconnected networks
Inventor: LIU CHUNG-ZIN
IPC: H04M7/00
Filed: 2000-08-03
Abstract: A telecommunication system routs real-time information traffic from an originating digital radio unit served by an originating network to a terminating unit served by a terminating network via an intermediate network interconnecting the originating and terminating networks. The originating digital radio unit has an encoder/decoder (e.g., a vocoder) for generating digital wireless frames from information that is input thereto. The originating network includes an originating node with an encoder/decoder for performing wireless-specific conversion of the digital wireless frames to digital wireline (e.g., PCM) traffic. The intermediate network includes an originating-end interface node with an encoder/decoder for compressing the digital wireline traffic for transport across the intermediate network. Optimization of communications routed between the originating and terminating units is achieved by routing the digital wireless frames without wireless-specific conversion being performed at the originating node of the originating network nor compression conversion being performed at the originating-end interface node of the intermediate network, such that the rate of information traffic throughput is maximized.

The method includes the steps of: providing a source document of the desired type; providing a sink document for providing access to the database; identifying a cut-set of links which is the smallest set of links such that removing them from the database completely disconnects the source document and its linked documents from the sink document and its linked documents into first and second subsets of documents, respectively; and defining the first subset of documents as desired type documents and the remaining documents as undesired type documents. Preferably, the database is the World Wide Web, the documents are web pages, and the links are hyperlinks between web pages. The identifying step preferably comprises: mapping at least a portion of the database into a graph structure; and applying a maximum flow algorithm to the graph structure, the subset of the graph structure which remains after application of the maximum flow algorithm being the first subset of documents. Also provided are a computer program product and program storage device for carrying out the method of the present invention and for storing a set of instructions to carry out the method of the present invention, respectively.

IPC: H04M3/533
Filed: 2000-10-18
Abstract: Using the present invention from a telephone set interface, users will be able to compose, reply to and forward messages. Once a directory is established, simply speaking the name of a message recipient will suffice to address a message. The spoken name of the intended recipient is compared to pronunciations of names of possible recipients in the directory until a match is found. An e-mail address of the match may then be used for addressing an outgoing e-mail. Alternatively, a telephone number of the match may be used for addressing an outgoing voice message. Other directories (system, corporate, public) may also be queried to match the spoken name.

Title: Method for manufacturing a fibre mat, fibre mat and use of such fibre mat
Inventor: PALLESEN BODIL ENGBERG
IPC: D04H1/58
Filed: 1999-04-29
Abstract: There is described a new method for making a fibre mat under the use of plant fibres, preferably from flax and hemp. The fibres are pre-treated and shortened, whereafter they are separated for establishing a fibre mass comprising single fibres with lengths within a desired interval. Hereafter, the fibre mat is produced by a dry-forming process as the fibres are oriented randomly in the fibre mat. The dry-forming process preferably takes place by using a former head which is placed above a vacuum box as the fibres are deposited on a former wire between these two elements. The plate is fixed as inter-fibre bonds are established between the single fibres. The inter-fibre bonds may be established with or without the use of binders. The formed fibre mats will be open and airy, but at the same time sufficiently stable and cohesive for handling. A field of application for the fibre mat will be isolation.

The cartridge receiver has a perimeter and the opening at the upper end of the base completely surrounds the perimeter of the cartridge receiver. The hollow space of the base is adapted for containing a shaving preparation, such as a soap cake, a liquid soap, shaving cream or a body wash and may be combined with skin beneficial ingredients and/or scent. In one embodiment, the body of the shaving assembly includes an adjusting element so that an adequate supply of the shaving preparation may be supplied completely around the perimeter of the cartridge receiver. In other embodiments, the shaving assembly includes a resilient element for urging the shaving preparation toward the upper end of the body. The cartridge receiver may also be movable for changing the position of the razor blade relative to the shaving preparation. The shaving assembly may also include a razor embedded in a mass of shaving preparation so that the cutting blades of the razor lie in substantially the same plane as the top surface of the shaving preparation.
