Inventor: HAMADA HITOSHI
IPC: H01M8/02
Filed: 1998-12-17
Abstract: An improved fuel cell makes uniform partial gas pressure of a fuel gas flowing through a gas passage formed between an electrode and a separator of a fuel cell, activating an electrode reaction in a whole region of the electrode surface along the gas passage.  The inlet and outlet for the fuel gas are disposed on a diagonal line of the separator to define a gas passage such that fuel gas smoothly flows even though portions of the passage away from the diagonal line.  This may reduce the separator size and improve the volumetric efficiency of the fuel cell and the diffusibility of fuel gas as well as the drainage of water produced by the electrode reaction.

Title: Fault management system for a telecommunications network
Inventor: CHASKELL ANDREW DAVID
IPC: H04M3/00
Filed: 1997-11-12
Abstract: There is described a method of operating a fault management system for an access network which forms part of a public telecommunications network. In the access network, terminating lines in the form of pairs of copper wires extend from a local switch (10) through a series of nodes to terminal equipment provided for user of the network. The fault management system includes a test head (104) and an access network management system (102). Each night, the test head (104) performs a series of tests on each of the terminating lines. The results of the tests are transmitted to the access network management (102). The test results are then converted into circuit scores, each of which is indicative of the operational quality of the tested circuit.  For each node, the circuit scores of the tested circuits passing through the node are combined to produce a node score which is indicative of the operational quality of the node. In order to identify the node having the worst operational quality and therefore most in need of investigation, the nodes are ranked in accordance with their node scores. When a customer reports a fault, the test head (104) performs a series of tests on the customer's line and transmits the results to the management system (102). The management system (102) checks the test results for the presence of a suspected fault and identifies the nodes through which the line passes. Then, for each of the identified nodes, it evaluates a score for each one of a set of factors and combines the scores to produce a combined score representative of the likelihood of the suspected fault being present at the node. In order to assist in identifying the node which is causing the suspected fault, the nodes are then ranked in accordance with their combined scores.

Patent CA-2280811-A1 (CA)
Inventor: PACKARD BEVERLY S
IPC: C12N5/071
Filed: 1998-02-20
Abstract: The present invention provides for novel reagents whose fluorescence increases in the presence of particular proteases. The reagents comprise a characteristically folded peptide backbone each end of which is conjugated to a fluorophore. When the folded peptide is cleaved, as by digestion with a protease, the fluorophores provide a high intensity fluorescent signal at a visible wavelength. Because of their high fluorescence signal in the visible wavelengths, these protease indicators are particularly well suited for detection of protease activity in biological samples, in particular in frozen tissue sections. Thus this invention also provides for methods of detecting protease activity in situ in frozen sections.
Patent CA-2281181-A1 (CA)
Inventor: BEALL CLIFFORD H
IPC: E21B34/16
Filed: 1999-08-27
Abstract: An improved control system, particularly useful for Subsurface Safety Valves (SSVs) is disclosed. The control system has an operating piston which acts on a flow tube to move a flapper to an open position. The flapper is spring-loaded to close when the flow tube moves up. A return spring acts on the piston to lift the flow tube to allow the flapper to close. The operating piston is exposed to a control line from the surface as well as to a bypass piston.   Opposing the hydrostatic forces of the control line is a pressurized chamber with a pressure in excess of the hydrostatic pressure. A secondary chamber acts on one side of the equalizing piston and is pressurized to a pressure less than the anticipated hydrostatic pressure in the control line. The system, including the operating piston, is configured so that when leakage occurs into or out of the control system in many places, the SSV will fail toward its failsafe closed position.

Title: Procede de production de panneaux composites et de moulures faconnees
Inventor: SEIDNER MARC A
IPC: B27M3/08
Filed: 1998-03-12
Abstract: Un procédé de fabrication débute avec la formation d'un panneau de réception (200), lequel définit une pluralité de rainures parallèles espacées (206) s'étendant longitudinalement. Le panneau de réception (200) présente une surface ouverte le long de laquelle sont exposées les rainures (206) et une surface opposée (202) de laquelle les rainures sont inaccessibles. Ensuite, il est préférable que la couche de plaquage soit en bois, mais les substrats peuvent être constitués d'un matériau moins cher tel qu'un matériau composite. Une fois le panneau de réception fabriqué, il est arqué pour former un arc autour d'un axe parallèle aux rainures (206). Alors que le panneau de réception est à l'état arqué, des bandes (210), de préférence en bois, sont insérées dans les rainures. On applique un adhésif sur une interface entre les bandes (206) et les surfaces des rainures ainsi que les bandes de bordure. On fait alors revenir le panneau de réception à un état non arqué, et cela de manière simple en cessant d'exercer les forces l'ayant amené à prendre une position arquée. On peut couper le panneau composite à travers les bandes pour former une pluralité de segments pouvant être utilisés comme moulures façonnées. Le découpage peut être effectué par passage du panneau composite sur un scie à refendre présentant une pluralité de lames parallèles.

Abstract: On a réussi à isoler de lignées cellulaires de type ostéoblastes trois gènes codant des protéines sécrétées par une membrane à l'aide d'un procédé de clonage spécifique des protéines sécrétées par une membrane. Après avoir analysé un de ces gènes, on a découvert que la protéine codée par ce gène est une nouvelle protéine réceptrice qui comporte une région extracellulaire unique, qui se fixe aux membranes cellulaires par l'intermédiaire d'une molécule GPI ancrée et supporte dans celle-ci une région répétitive riche en cystéine conservée dans la super famille du récepteur du facteur de nécrose tumorale (TNF). On a également découvert que, lorsque cette protéine est en grande partie exprimée dans une lignée cellulaire de type ostéoblastes, la prolifération des cellules est réprimée, les cellules sont modifiées morphologiquement et l'activité de la phosphatase alcaline, qui est une des indications de la différentiation des ostéoblastes, est élevée.

Abstract: La présente invention concerne un système (100) dénumériseur de mise en forme d'erreurs comprenant un séparateur (102), un jeu de dénumériseurs (104, 108), un jeu de filtres analogiques (106, 108) facultatifs, un dispositif de sommation (112) et un filtre analogique (114) facultatif. Le séparateur (102) sépare le signal d'entrée numérique en un ensemble de signaux à basse résolution dont un seul possède une puissance significative dans la bande de signal du système. Ces signaux sont dénumérisés par des dénumériseurs (104, 108) de mise en forme de désadaptations; dans certains modes de réalisation, ils sont filtrés par des filtres analogiques (106,108,); et ils sont ensuite additionnés par le dispositif de sommation (112). Des imperfections dans les dénumériseurs (104,108) utilisés ne provoquent que de très petites erreurs dans la bande de signal, et ces erreurs sont essentiellement sans corrélation avec le signal numérique d'entrée. Le système dénumériseur de la présente invention est comparable à un dénumériseur à élément à échelle dans lequel la distorsion est transformée en une composante de bruit possédant une très faible puissance dans la bande de signal.

IPC: F16H61/46
Filed: 1999-11-03
Abstract: A remote drop box can be provided for tractor hydraulic drives; however, a system for providing lubrication to and cooling of the remote drop box is necessary. Maximum drawbar pull and maximum road speed capability are both,desirable when a variable hydrostatic motor defines the working range. The hydrostatic motor must be operated very close to its maximum rated operating speed during roading, which leaves very little margin for overspeeding that occurs when the tractor is roading downhill. An improved overspeed control is also desirable. A problem encountered when a hydrostatic drive is used with a high torque engine in that, as the engine speed drops, the available charge pump flow also drops and eventually reaches a point where the required servo pressure to maintain the hydraulic pump in stroke cannot be maintained. Such a condition needs to be alleviated to provide an effectively operating hydrostatic drive system. Load sensing hydrostatic drive systems can encounter vibrational or surging problems, particularly when flow compensators in valving interact with the flow compensator of the hydraulic pump. This interaction will cause rhythmic flow pulsations or surging within the hydraulic system, which is undesirable. Stabilizing the hydraulic system can be accomplished with an attenuator/hose assembly.
