Patent CA-2431385-A1 (CA)
Title: Method for controlling/regulating the distribution of the injection molding compound, and multi-cavity injection mold
Inventor: WERFELI FRIEDRICH
IPC: B29C45/78
Filed: 2001-11-09
Abstract: The invention relates to a method and to a device for controlling/regulating the distribution of the injection molding compound in multi-cavity injection molds, especially for molds with a large number of cavities, for example 48 to 128 cavities. The invention distributes the injection molding compound in groups of, for example, four to twelve nozzles.  Each group is provided with one classical nozzle, as the master nozzle, that is controlled via the local heating capacity and temperature sensors. All other nozzles or cavities of the same group are configured as slave nozzles that have no temperature sensors. The virtual actual temperatures are computed via saved model computations and are displayed on the user panel. The user is thus provided with the desired/actual temperature values for every nozzle and can thus influence every single nozzle, depending on the result, in the form of temperature values. The invention allows reduction of the regulation to a minimum while the quality of the injection molding compound distribution is maintained, thereby reducing production costs and allowing a more economic operation of the control and regulation systems.
Patent CA-2433634-A1 (CA)
Inventor: BANDARU RAJANIKANTH
IPC: C12Q1/68
Filed: 2002-01-04
Abstract: L'invention concerne un nouveau procédé de ligature d'oligonucléotides contenant des 5'-phosphorothioates sur des matrices complémentaires, par l'action d'ADN ligases. Cette réaction est facilement appliquée à la synthèse d'un ADN monocaténaire circulaire contenant une liaison 5'-phosphorothioate au site de la jonction de ligature. L'efficacité de la réaction de ligature dirigée par 5'-phosphorothioate par une réaction d'ADN ligase dépendant d'ATP est semblable à la ligature de 5'-phosphate traditionnelle. L'invention concerne également l'utilité de la ligature enzymatique dans le sondage de séquences spécifiques d'ADN. L'invention concerne en outre une nouvelle ligature non enzymatique de 5'-phophorothioates appliquée à la synthèse d'ADN monocaténaire circulaire de phosphorothioate et de phosphate, ainsi qu'un procédé de détection de la présence d'un mauvais appariement d'une paire d'oligonucléotides habituellement complémentaire au moyen d'une technique à base d'enzymes qui montre la présence d'un mauvais appariement par l'impossibilité de former un cercle d'ADN monocaténaire ligaturé qui peut éventuellement être amplifié au moyen de procédés habituels d'amplification par cercle roulant.

Title: Removable seal of essentially gas-impermeable thermoplastic elastomer
Inventor: VARMA RAJESH KUMAR
IPC: B65D41/04
Filed: 2002-02-12
Abstract: A thermoplastic elastomer ("TPE") which is oxygen-permeable is provided with excellent barrier properties against oxygen by melt-blending with a liquid polyisobutene oil plasticizer in an amount insufficient to render the plasticized elastomer tacky. If made tacky, enough detackifier is used to allow the product to be formed into a removable seal. The TPE may be a conventional thermoplastic vulcanizate or a block copolymer of a vinylaromatic compound, typically styrene, and a conjugated diene, typically butadiene or isoprene, or mixtures thereof, the block may be a diblock, triblock or higher block, but the preferred polyblock copolymer is a triblock with styrene end-blocks and a butadiene/isoprene mid-block. Preferably the diene mid-block is hydrogenated to provide a poly(lower)monoolefin mid-block. When the TPE is a TPV, some or all of the mineral oil used to make the TPV processable may also be substituted with the polyisobutene plasticizer. The elastomeric product is particularly useful for sealing elements for containers in which foods, beverages and medical products must be preserved for a long period.

Abstract: A packet switch router processes downstream digital information to provide dedicated bandwidth to each subscriber destination in a hybrid fiber coax (HFC) network. The router includes a network module that terminates a network connection, a switch that forwards data from the network module, and a channel module. The channel module includes a switch interface, a cell processing engine, one or more modulators, and a radio frequency (RF) transmitter network. The switch interface forwards packetized data from the switch to the cell processing engine. The cell processing engine organizes the packetized data into multiple data streams, encapsulates data in each data stream into data cells, and multiplexes the data cells into a multiplexed cell stream.  Each modulator is configured to modulate a multiplexed cell stream into an analog signal. The RF transmitter network up converts and combines a plurality of analog signals into a combined electrical signal for transmission.

Title: Photochemical system and method for the removal of pcdd or pcdf compounds from industrial process emissions
Inventor: GOSHAW DAVID
IPC: B01D46/02
Filed: 2002-04-15
Abstract: A photochemical process for removing or minimizing the concentration of PCDD or PCDF compounds within an industrial gas stream. The process includes the direct photolysis of PCDD or PCDF compounds. Light within a particular spectral range is irradiated (28) into the gas stream and is absorbed by the PCDD and PCDF compounds in the presence of a hydrogen donor and this results in producing a lower chlorinated PCDD or PCDF compound form. In addition, th e gas stream may be treated (22) by removing particular matter therefrom and thereafter subjected to the above-described irradiation (28). Further, as another optional step, the gas stream may be irradiated (14) with the specif ic purpose of targeting PCDD and PCDF precursor compounds. In this case, the irradiation is absorbed by the precursor compounds causing them to be chemically modified to different compounds that do not participate in chemic al reactions that result in the formation of PCDD and PCDF compounds.

Title: Methods, systems, and software for automated growth of intelligent on-line communities
Inventor: SARHAN NABEIL O
IPC: G06F17/30
Filed: 2002-03-29
Abstract: In recent years, computers have become everyday communication tools, fast approaching the commonness of telephones and televisions. Driving this approach is rapid growth of the much-heralded Internet, which functions as a planetary communications system, enabling users to communicate with each other, to transmit data to each other, and to search for data of particular interest. Two problems stemming from the rapid Internet growth are the time and effort often necessary for users to find data of particular interest and the difficulty for users to find and communicate with other users who share interests in similar kinds of information. Accordingly, the present inventor devised systems, methods, and related software for encouraging and managing growth of databases, particularly theme-oriented databases, such as health-in-formation databases (Figure 5). One exemplary method entails establishing a theme-oriented database (520), receiving user contributions to the database, and granting users access rights to the database (152, 154, 156, 158) based on their contributions. The exemplary method also scores user contributions for quality and/or relevance to the theme of the database, and grants access rights based on the scores. Additionally, the exemplary method records the queries users of the database and facilitates communications between users having similar queries.
