Patent CA-2285916-A1 (CA)
Title: Automatically continuously variable fold position sheet folding system with automatic length and skew correction
Inventor: FERRARA JOSEPH J
IPC: B65H45/14
Filed: 1999-10-13
Abstract: An improved sheet folder for flimsy printed sheets with an automatic fold position correction system. The folder may have an input sheet feeder, a fold chute with a chute entrance, reversible sheet feeding rollers in the fold chute adjacent to the chute entrance, fold rollers, a folded sheets output path, and a sensor system for sensing the length of folded sheets in the folded sheets output path. A sheet to be folded is may be partially fed into the fold chute, engaged by the reversible rollers, and fed thereby further into the chute by a selected distance corresponding to a desired folding position along the sheet. Then, the reversible rollers are stopped at a selected sheet stopping position and reversed to feed the sheet into the fold rollers, cooperatively with the input sheet feeder. The fold rollers feed the folded sheet into the folded sheets output path. The sensor system there provides a control signal modifying the selected stopping position of the reversible rollers, to provide a fold position correction system. For integral or separate fold skew correction, the reversible rollers are transversely spaced and separately servo driven, and the sensor system is a plural sensor array extending transversely across the folded sheets path to provide skew correction signals differently controlling the selected stopping positions of the separately driven reversible rollers. Additionally disclosed is a special fold position correction system for 1/2 or even-folded sheets.

Title: A method and an apparatus for production testing involving first and second permeable formations
Inventor: WOIE RUNE
IPC: E21B49/00
Filed: 1998-04-06
Abstract: When production testing a permeable first formation (4), fluid flowing out therefrom is subjected to a pressure measurement and a flow rate control. In order to avoid bringing up the fluid flowing out during the production test to surface position where the fluid's inherent explosion and fire risk as well as poisonousness would cause substantial problems, a fluid flow path arranged for fluid transfer between the formations (4, 6) is established between said first formation (4) to be production tested and a second permeable formation (6), said fluid flow path which, in a suitable apparatus, is constituted by a channel-forming pipe (8). From this channel second permeable formation (6) receives said fluid and keeps it for some time. In the position of use, the apparatus is assigned sealing means, i.a. annulus packers (10, 11, 12) which are placed such that fluid flow between the formations (4, 6) is limited to only follow said fluid flow path.

Title: Synthese d'hydrocarbures en suspension associee a une filtration externe des produits
Inventor: DEGEORGE CHARLES W
IPC: C10G2/00
Filed: 1998-05-15
Abstract: Cette invention se rapporte à un procédé de synthèse d'hydrocarbures en suspension qui fait usage d'une cuve de filtration de suspension, externe au réacteur à combustible en suspension. On fait passer la suspension en provenance du réacteur par une ou plusieurs zones de retrait des gaz et des solides, l'une de ces zones au moins pouvant être présente dans le réacteur et la cuve, de manière à réduire la teneur en gaz et en solides de la suspension avant qu'elle n'entre au contact du filtre dans la cuve. Le filtre sépare le liquide contenant les hydrocarbures en suspension des gaz et des solides, ledit liquide constituant le filtrat qui est transféré en vue de sa valorisation. Des robinets équipant les conduits pour gaz et fluides permettent d'isoler la cuve de filtration du réacteur pour l'entretien, pour remplacer les filtres et pour faciliter la surveillance de l'écoulement de la suspension dans la cuve. Il est possible d'injecter un gaz riche en hydrogène dans la cuve de filtration de manière à empêcher la désactivation du catalyseur. Lorsque le réacteur fonctionne, la suspension est mise en circulation de manière hydraulique entre le réacteur et la cuve en raison des différences de densité.

Title: Start-up method and apparatus in refrigeration chillers
Inventor: CAREY MICHAEL D
IPC: F25B1/047
Filed: 1998-05-12
Abstract: The existence of inverted start conditions in a refrigeration chiller (10) is identified by sensing the liquid level (64, 68) in the chiller evaporator (20). That liquid level (64, 68) is indicative of the location of the chiller's refrigerant charge at start-up. If the sensed liquid level (64, 68) is below a predetermined level, an inverted start condition is verified to exist. Failed starts and chiller system shutdowns are reduced or avoided.

En réponse aux phases de ce processus, un signal optique est généré à la surface de chaque microparticule, signal qui est caractéristique de l'interaction entre l'analyte porté par la microparticule et le réactif de traitement distribué. On analyse les différents analytes simultanément en collectant et en enregistrant des images des signaux optiques générés par toutes les microparticules du réseau plan. L'invention est caractérisée par la corrélation de la séquence des signaux optiques générés par chaque microparticule du réseau plan au cours du processus d'analyse.

Abstract: The invention relates to a communications network (MPLS-D) with two or more network nodes (ISR1 to ISR3) each provided with a Layer 2 switching element (SW1 to SW3) and a switch controller (SC1 to SC3) for controlling the respective Layer 2 switching element (SW1 to SW3), to such a network node, to such a switch controller, and to a method of supporting shortcuts through such network nodes. The switch controller (SC1) is composed of several independent modules, namely a shortcut control module, at least one trigger module, and at least one protocol module. If respective predetermined criteria are satisfied, the at least one trigger module initiates the assignment of a shortcut, which is formed by a direct Layer 2 connection, to a Layer 3 connection. The shortcut control module communicates with the respective Layer 2 switching element (SW1), initiating the assignment of data packets to shortcuts by marking data packets with a label assigned to the respective shortcut, and controlling the switching of shortcuts through the respective Layer 2 switching element (SW1). The at least one protocol module distributes labels to switch controllers (SC2, SC3) of other network nodes (ISR2, ISR3) of the communications network (MPLS-D) and thereby coordinates the assignment of labels to shortcuts.
