Patent CA-2261196-A1 (CA)
Inventor: LAURENT JEAN
IPC: G01V1/42
Filed: 1999-02-18
Abstract: Méthode et dispositif de surveillance sismique permanente d'une formation souterraine au moyen d'un ou plusieurs ensembles d'émission-réception sismique comportant chacun une source (S) telle qu'un vibrateur et des récepteurs d'ondes élastiques tels que des géophones et/ou des hydrophones. - Un puits est foré dans le sol. Les récepteurs sismiques y sont descendus et couplés avec la formation environnante. La section du puits est élargie dans sa partie supérieure, de façon à constituer une cavité aux parois de laquelle est plaquée la source sismique. Les récepteurs et la source sont reliés à un station extérieure de commande et d'acquisition de signaux. Les puits peuvent être des puits d'exploration que l'on fore par exemple autour de puits d'exploitation de gisements recélant des fluides ou bien encore des puits mixtes d'exploration et d'exploitation. Chaque source peut également être couplée avec une cavité voisine du puits. Les opérations de mise en place de ces ensembles sont relativement simples et la zone d'emprise au sol des différents puits est réduite ce qui facilite leur intégration sur des chantiers d'exploitation de gisements. - Application à la surveillance de gisements pétrolifères ou de réservoirs de stockage de gaz par exemple.

Title: Method and system for automatic detection for isdn switch time in north america
Inventor: JOU LIANGWHA
IPC: H04Q11/04
Filed: 1997-08-11
Abstract: An ISDN modem is preprogrammed to operate by any one of multiple ISDN  protocols, and is provided with a setup program (200) wherein, with the modem connected to an ISDN switch, the multiple protocols (201, 204, 207) are automatically tested one-at-a-time until one is found by which a successful connection to the switch may be made, or until all fail. In the event a successful connection is made, that protocol in use at the time of the successful connection is selected for continued use. In the event that all preprogrammed protocols fail, a user is offered an input mechanism (211) whereby an alternative protocol selection may be entered for trial.
Patent CA-2264328-A1 (CA)
Inventor: JAMES DONALD
IPC: G01R31/306
Filed: 1999-03-01
Abstract: Disclosed is a method and apparatus for increasing the speed of electromagnetic emission scanning of an electronic device under test. Included is an array of electromagnetic emission detection probes, decoder and driver circuits to address a selected number of probes in the probe array in a predetermined manner, a micro-controller to instruct and supervise the decoder and driver circuits, an analogue to digital converter, a memory circuit, a system controller and a display. The device under test is energized and located adjacent to the array of probes. The micro-controller instructs the decoder and driver circuits to address, individually and successively a specific group or list of probes during a first scanning period. The emission level from each of the addressed probes is measured, digitized and stored in memory circuits as a first data set. The system controller integrates, scales, maps and displays the first data set on the display for interpretation by an operator concomitant with the next data set being collected by the micro-controller. Collected data sets are passed to the system controller for processing and the sampling steps are repeated until the operator receives the desired level of electromagnetic characterization and terminates the scan.

Title: Method and apparatus for well workover or servicing
Inventor: DALLAS L MURRAY
IPC: E21B33/03
Filed: 1999-05-12
Abstract: The present invention relates to a method and apparatus for the servicing or workover of a hydrocarbon well. The apparatus includes a pair of hydraulic cylinders pivotally mounted to a pair of base beams connected to each other. The cylinders are moveable from a horizontal position for transportation to a vertical position for operation in which position the two cylinders flank a wellhead and are adapted to lift the wellhead and attached production tubing using a workover beam and a lifting sub. The wellhead and production tubing can be rotated as or after they are elevated. A motor may be mounted to the workover beam to rotate the wellhead and the tubing. A calibrated pressure gauge may be used to indicate the weight being lifted. The apparatus can be wheel mounted and towed behind a crane truck. The advantage is a safe, economical and time-saving apparatus for performing jobs that previously required the setup and operation of a workover rig.

Abstract: A manifold (24) is interposed between a pipe bracket (26) and a service valve (30) of a passenger rail car (20) braking system (22) also having a brake application relay valve (32), a primary control reservoir (48), a emergency control reservoir (54), and a main reservoir (44). The manifold includes electronically controlled emergency fill (78), normal fill (80), vent (82), and bypass (84) valves and pneumatically controlled secondary emergency fill (136), secondary normal fill (138), secondary vent (140) and manifold relay (142) valves. Electrical signals are received by the electronically controlled valves (78, 80, 84) which then operate the pneumatically controlled valves (136, 138, 142) to transmit pressure from the control reservoirs (48,54) to a brake application relay valve (32). The brake application relay valve then operates to transmit pressure from a main reservoir (44) to a braking device (36) which brakes the passenger rail car (20). When the braking device (36) is to cease braking, the vent valves (82, 140) operate to vent pressure from the brake application relay valve (32) which then ceases the transmission of pressure from the main reservoir (44) to the. braking device (36). Speed control orifices (174, 176) and a volume adding chamber (160) are used to fine tune the braking system (22).

IPC: A61F2/958
Filed: 1998-03-06
Abstract: L'invention concerne un cathéter à ballonnet élastique présentant une réponse élastique améliorée et une dilatation longitudinale réduite, et son procédé de fabrication. Le ballonnet comprend un polymère bloc styrène-éthylène-butylène-styrène (SEBS), qui est pré-étiré dans le sens longitudinal lors de son procédé de fabrication. Afin de fixer la longueur efficace d'un ballonnet de cathéter, le cathéter est doté d'au moins une barrière à adhésif, qui empêche l'adhésif de s'infiltrer par effet de mèche dans la longueur efficace du ballonnet. De préférence, on introduit deux tubes thermodurcis avec un diamètre extérieur de taille presque équivalente au diamètre intérieur du ballonnet à l'extrémité distale du cathéter. Après que le cathéter a été correctement mis en place, on applique l'adhésif au niveau des extrémités proximale et distale du ballonnet. Comme l'adhésif s'infiltre dans le ballonnet, les tubes thermodurcis arrêteront en définitive l'adhésif de manière à éviter qu'il ne continue de s'infiltrer par effet de mèche dans la longueur efficace du ballonnet. Un autre aspect de l'invention concerne un procédé de fabrication de cathéter à ballonnet permettant d'améliorer le centrage du ballonnet sur le cathéter. Après étirement d'un tube de ballonnet, le tube étiré est fixé sur un dispositif de serrage et stabilisé à environ 100 ·C pendant 15 mn. Cette étape de stabilisation offre la garantie qu'un ballonnet monté sur un cathéter gonflera de manière uniforme.
