Patent CA-2308178-C (CA)
Inventor: BOWERS BRUCE O
IPC: C08C19/08
Filed: 1998-10-21
Granted: 2010-05-04
Abstract: L'invention concerne des procédés et un dispositif de production d'un substitut de polymères neufs à partir de déchets de caoutchouc vulcanisé, comme par exemple des pneus d'automobile. Ces procédés se déroulent sans utilisation de solvants ou de produits chimiques et le substitut résultant présente sensiblement les mêmes propriétés physiques que la matière neuve. Ce procédé et ce dispositif permettent d'effectuer une analyse initiale du matériel de récupération à traiter et de déterminer les paramètres de traitement pour ce matériau particulier. Le traitement effectif du matériau consiste à broyer les déchets de caoutchouc et à prétraiter le matériau broyé en l'exposant à de l'air chaud et sec avant de le traiter dans un environnement haute température et haute pression. L'environnement haute température et haute pression est créé par une enceinte sous pression dans laquelle le matériau prétraité est introduit puis exposé à un environnement haute pression et haute température variable, réglé de façon à optimiser la dévulcanisation du matériau. Le matériau est agité en continu pendant le traitement de manière à assurer un chauffage et une exposition uniforme des matériaux ce qui permet de produire un substitut utilisable sans diminution sensible des propriétés physiques telles que la résistance à la traction et la résistance à la déchirure.

Title: Method and apparatus for increasing fluid recovery from a subterranean formation
Inventor: KELLEY TERRY E
IPC: E21B43/00
Filed: 1997-12-01
Granted: 2006-06-27
Abstract: A downhole injector (10, 26, 38, 54) is provided at the lower end of the production tubing string (TS) for passing liquids from a downhole formation (F) into the tubing string while preventing gases from passing through the injector. The injector may include a screen (36) for preventing formation sand from entering the injector. The system may include a packer (44) in the annulus (A) above the injector. In one application, a vent tube (46) extends upward from the packer into the annulus for maintaining a desired liquid level in the annulus above the packer. A  plurality of through ports (40) establish fluid communication in the annulus above the packer and the production tubing string so that the downhole pump (P) may efficiently pump downhole fluids to the surface. The injector may be used with one or more lift valves (LV) for raising liquid. The injector may also be used with horizontal wellbores for increased hydrocarbon recovery.

Title: Self-locking chair
Inventor: LALIBERTE MARC
IPC: A47C1/022
Filed: 2000-10-17
Granted: 2004-04-27
Abstract: A self-locking system comprising a state selector for detecting the intent of an occupant to rise from a chair and then automatically causing a lock to block the mobility functions of the chair. The state detector is responsive to movement of an upper portion of the body of the occupant while the occupant is still supported in a normal seated position on the seat of the chair, thereby advantageously allowing the locking of the mobility functions of the chair to occur before the occupant starts to lift his weight from the seat of the chair.

Abstract: A packet-based protocol includes data flow control signals for efficient transmission of data on various interconnects, including high speed parallel and serial interconnects. The packet protocol also enables routing of data in large systems or across standard video and computing networks. The packet protocol is data independent and permits sharing of different types of video data over a common interconnect and system design. The packet protocol also offers a flexible method for routing data between devices. Command data also may be sent between devices using this protocol. Using this packet protocol, any data storage or data processing device may also operate as a switch and may implement data flow control over its input and output interconnects. Flow controlled data transfer may be implemented using this protocol in a manner that is independent of the transport medium of the interconnect.

Abstract: In a satellite network with on-board switching and bandwidth on demand, traffic monitoring is required to facilitate billing data collection and to avoid congestion at the satellite. In addition to traffic monitoring, performance monitoring is necessary to quickly respond to link degradation or possible equipment anomalies.  Monitoring terminals (MTS) specially equipped with traffic measuring and policing and link performance measuring capabilities are used to monitor traffic and performance. The monitoring terminal (MTS) is located in each satellite beam to perform the monitoring functions for that beam. The monitoring terminals (MTS) are low-cost terminals that receive down-link traffic in their respective beam, and record statistics on a per transmit-terminal or per virtual connection basis. Records are periodically transmitted to a central location where they are processed for billing, enforcing traffic contracts, and taking actions against link degradations.

Title: Sensor apparatus with two resonant transducers and a single conductor
Inventor: ATHERTON ERIC
IPC: G01L9/00
Filed: 2001-03-27
Granted: 2011-06-14
Abstract: A measurement head particularly for borehole use can measure multiple parameters with no electronics in the head and only a single conductor cable. Double-ended tuning forks (26, 28 and 38, 40) in the head are arranged to respond to different parameters such as temperature and pressure by adjusting their resonant frequencies. A drive signal on the conductor (50) is applied to transducers (30, 32, 42, 44) on all the tuning forks and those whose instantaneous resonant frequency is close will resonate. The signal is removed and the transducers return a decaying signal at the resonant frequency along the conductor. Other drive frequencies are tried, to locate the other sensors whose frequency ranges are separate.

Title: Seal configuration to reduce seal extrusion
Inventor: DELBRIDGE SCOTT
IPC: F16J15/06
Filed: 2002-11-28
Granted: 2009-04-14
Abstract: A seal configuration to reduce seal extrusion includes a body having an opening with inwardly tapered peripheral sidewalls. A closure having an attachment portion larger than the opening and an axially projecting stopper portion adapted to fit closely within the opening. The stopper portion has an endless peripheral seal groove extending in spaced relation around the axis in which is positioned a peripheral seal which conforms to the tapered peripheral sidewalls. A backing ring of pliable memory retaining material is positioned between the peripheral seal groove and the attachment portion of the closure. The backing ring resists extrusion flow under pressure. In response to an increase in internal pressure within the body, the peripheral seal is extruded against the backing ring which deforms to prevent the peripheral seal from entering the extrusion gaps.
