Abstract: A communication line is installed in a network by automating a design phase and a configuration phase for the service and by automating the failure recovery in either of the phases. In the design phase, an optimal route for the communication line is found, and the network components are provisioned and assigned. If the assigned network components are not available or can not be validated, the components causing the failure are marked, and the design phase is retried without the marked components. After the design phase, the configuration phase begins. The circuit design is tested against actual network components. If the test is passed, the actual network is configured according to the circuit design and the circuit is activated. If there is a network component failure during the configuration phase, the good route elements in the design are released while the failed network components are marked. The design phase is retried.

Patent CA-2425130-C (CA)
Inventor: SEARS JAMES B JR
IPC: B22D27/04
Filed: 2001-09-12
Granted: 2006-10-10
Abstract: An improved process of operating a continuous casting mold of the type that includes at least one mold surface and at least one coolant passage that is in thermal communication with the mold surface includes determining based on at least one factor whether it would be most advantageous to direct coolant through the coolant passage in a first direction or in a second, opposite direction. For example, if the mold liner is beneath a predetermined thickness it may be advantageous to circulate the coolant so that it enters the water jacket and the coolant slots that are defined in the mold liner at the bottom and exiting from the top so that there is some prewarming of the coolant before it reaches the meniscus region. Conversely, if the mold liner is thicker it may be desirable to introduce the coolant at the top of the water jacket, thus enhancing the cooling effect in the meniscus region.

Title: Systeme et procede de collimation et de reorientation des faisceaux
Inventor: CAPEWELL DALE L
IPC: G02B6/42
Filed: 2001-10-31
Granted: 2010-03-09
Abstract: L'invention porte sur connecteur de fibre optique comprenant un prisme, une ferrule et une lentille asphérique. Le prisme comporte un élément de calage triangulaire doté d'une première surface, d'une deuxième surface et d'une base. La ferrule guide la fibre optique afin que cette dernière soit en contact avec la première surface du prisme. La lentille asphérique est intégrée dans la deuxième surface et positionnée de manière à ce que le prisme puisse réorienter un faisceau lumineux, à un certain angle par rapport à un axe de l'entrée de la source optique, par une réflexion interne totale au moyen de la base de l'élément de calage triangulaire. La lentille asphérique est utilisée afin de collimater le faisceau de lumière réorienté ou de le focaliser avant qu'il ne soit réorienté. Ce dispositif peut par exemple être utilisé à l'intérieur d'un système WDM (multiplexeur en longueur d'onde) afin de multiplexer et démultiplexer plusieurs longueurs d'onde de lumière, au moyen d'une configuration de trajet optique en zigzag et de filtres à couche mince afin de dissocier les longueurs d'onde.

Abstract: Apparatus and method for handling a container having a removable cover, e.g., a vial for holding a biological fluid specimen. The container may have therein an internal element that is releasably coupled to the cover, such as an assembly for processing the specimen in the container. The method involves applying an external force to the covered container sufficient to release the internal element from the cover, and then dislodging the cover from the container. The external force may be an acceleration force applied to the container, such as an impact force to the bottom of the container, or direct contact with the cover with sufficient force to deflect the cover inwardly. A  vertically mounted pressing member and a movably mounted gripper can be used.  The pressing member may act to eject the cover from the gripper after the container is clear of the gripper.
