Patent CA-2340755-A1 (CA)
Inventor: YAMAGISHI KIYOSHI
IPC: G01F1/684
Filed: 1999-08-16
Abstract: A strainer integrated flowmeter (201) which comprises a strainer section (203) including a housing (202) formed with a flow passage (207), a filter member (209) and a filter member insertion cylinder (210), and a flowmeter section (204) including the housing (202) formed with a flow passage (208) and a flow sensor (226). The housing (202) for the strainer section (203) and flowmeter section (204) is shared therebetween and integrated, with the flowmeter section (204) disposed downstream the strainer section. The housing (202) has an exhaust hole (215) connected to the flow passage (207). This arrangement makes it difficult for foreign matter to enter the flowmeter and prevents air bubbles from remaining in the flow passage, thus making it possible to measure the flow rate of a fluid flowing through a pipeline accurately for a long time.

Title: Composes et procedes permettant d'ameliorer l'apport d'un polynucleotide libre
Inventor: MALONE JILL G
IPC: A61K38/00
Filed: 1999-08-19
Abstract: La découverte de procédés pharmaceutiquement définis, non toxiques et simples pour modifier génétiquement des cellules et des tissus permet de développer des variétés de médecines moléculaires. L'administration d'un polynucléotide libre, direct ou nu est un procédé d'apport de polynucléotide pharmaceutiquement défini, simple, et apparemment sûr. Des essais cliniques effectués sur des souris, des macaques et des hommes ont montré une transaction de différents tissus, tels que des tissus respiratoires, après l'application directe d'un polynucléotide libre. Toutefois, une transfection directe d'ADN est relativement inefficace en comparaison de beaucoup de systèmes de transfection. Cette invention concerne des agents d'amélioration de transfection qui augmentent l'activité de transfection d'un polynucléotide libre, ce qui facilite le développement d'alternatives simples et sûres à la transaction de tissu, et plus particulièrement à la transaction de tissu respiratoire. Les expériences décrites dans les spécifications montrent que des nucléases, à la fois extra- et intracellulaires, présents dans de nombreux fluides biologiques, tel qu'un fluide respiratoire, accélèrent le dégagement de plasmide biologiquement actif à partir du tissu, et que la co-administration d'un inhibiteur de nucléase avec un polynucleotide libre a pour effet une amélioration marquée de l'expression du polynucléotide considéré. Ces découvertes justifient l'invention d'un système d'apport de polynucléotide amélioré, et d'une technologie de transfection à base de plamide libre.

Title: Friction stir grain refinement of structural members
Inventor: FORREST R SCOTT
IPC: B64C1/00
Filed: 2001-05-16
Abstract: The present invention provides an improved structural assembly constructed of a plurality of structural members secured together. At least one of the plurality of structural members defines a first region characterized by comparatively high operational stress and a second region having a locally refined grain structure positioned such that the second region at least partially encompasses the first region to thereby enhance the strength, toughness and fatigue resistance of the at least one structural member in the first region. The present invention also provides a method for selectively improving the strength, toughness and fatigue resistance of a structural member in a region of high operational stress including the steps of casting the structural member in a pre-selected configuration. Regions of the structural member having comparatively high operational stress are identified. The structural member is secured to prevent movement. The region of the structural member having comparatively high operational stress is then mixed with a rotating friction stir welding probe to locally refine the grain structure of the structural member within the region of high operational stress to thereby improve the strength, toughness and fatigue resistance of the structural member in the region. The structural member can be secured to other structural members to form the frame of an aircraft. The improved structural assembly will have an increased operational life, as well as require less stock material with a corresponding decrease in the overall weight of the assembly.

Patent CA-2358180-A1 (CA)
Inventor: BRAVIN BEN
IPC: B65H19/18
Filed: 2001-10-02
Abstract: An automatic tape crossover machine having two feeding mechanisms to supply running and new tapes, respectively. A powered cutter is provided through which the running tape is to pass and be cut in response to a cut signal, where the cutter is positioned downstream of the first tape feeding mechanism. The machine also includes a joining mechanism at which a portion of a new tape is to be joined to the running tape in response to a join signal. Control circuitry automatically determines whether a tape exhaustion condition has been reached and asserts the join and cut signals to join the running and new tapes and to cut the running tape, before the tape feeding mechanism is emptied of the running tape. The machine thus allows the automatic transition from the running tape to the new tape, i.e. without requiring the presence or manual assistance of a human operator when joining the two tapes. In addition, the process line speed need not be altered for the crossover, thereby reducing the probability of inconsistencies in product quality.

Title: Mismatch repair detection
Inventor: FAHAM MALEK
IPC: C12Q1/6897
Filed: 2000-03-14
Abstract: Mismatch Repair Detection (MRD), a novel method for DNA-variation detection,  utilizes bacteria to detect mismatches by a change in expression of a marker  gene. DNA fragments to be screened for variation are cloned into two MRD plasmids, and bacteria are transformed with heteroduplexes of these constructs. Resulting colonies express the marker gene in the absence of a mismatch, and lack expression in the presence of a mismatch. MRD is capable of detecting a single mismatch within 10 kb of DNA. In addition, MRD can analyz e many fragments simultaneously, offering a powerful method for high-throughpu t genotyping and mutation detection.

Title: Identifying network servers capable of hosting a database
Inventor: BEILHARTZ DENNIS RUSSELL
IPC: G06F9/50
Filed: 2001-12-19
Abstract: An embodiment of the present invention provides an identification mechanism for identifying network servers capable of database hosting. The network servers are also capable of transmitting identification indicating their capability to host a database.  The identification mechanism operates over a network for networking a collection of network servers in which some are network servers capable of hosting a database. The identification mechanism begins by requesting an allocation of memory to receive transmitted identification of network servers capable of database hosting. Then the mechanism transmits a broadcast message, to the collection of network servers via the network, requesting transmission of identification of the network servers capable of database hosting. The mechanism waits for the allocated memory to substantially receive transmissions of identification of network servers capable of database hosting. Subsequently, the mechanism provides the received transmitted identification from the allocation of memory.

Title: Apparatus for reducing combustor exit duct cooling
Inventor: GATES ROGER J
IPC: F02C7/18
Filed: 2000-06-07
Abstract: The present invention is directed to gas turbine engines in which distinct components are integrally cast so as to increase resistance to thermal stress and thus decrease the amount of cooling airflow required to maintain the structural integrity of the components. The inner duct wall (34) of a reverse airflow duct is integrally cast with a circumferentially extending shroud (42) surrounding the stator vanes (38) forming the turbine nozzle. The integral casting permits the inner duct wall (34) to withstand greater degrees of thermal stress and thus require less cooling (47).
