Title: Reservoir combine de fluide de cardiotomie et de sang veineux
Inventor: MCBRIDE ROBERT R

Abstract: Selon une réalisation préférée de la présente invention, un réservoir combiné (10) de fluide de cardiotomie et de sang veineux comporte un canal d'écoulement séparé destiné au fluide de cardiotomie et au sang veineux, ainsi qu'un élément de filtration (66) du fluide de cardiotomie servant aussi de démousseur initial. Le fluide de cardiotomie est démoussé, filtré et à nouveau démoussé. Le sang veineux est démoussé, puis les deux fluides sont combinés pour s'écouler du réservoir (10). La zone de filtration (152') du fluide de cardiotomie est séparée, pour un meilleur résultat, de la zone d'un élément de démoussage final (152"). Par conséquent, le fluide de cardiotomie et le sang veineux peuvent s'écouler simultanément dans cet élément de démoussage final (152") le long de voies d'écoulement séparées. La conception du réservoir (10) donne une plus grande liberté dans le choix d'une de zone de filtration (152') adaptée du fluide de cardiotomie tout en permettant la sélection de la zone de l'élément de démoussage effectif de façon à obtenir des débits acceptables du fluide de cardiotomie et du sang veineux dans diverses conditions de fonctionnement du réservoir (10). On obtient un rapport avantageux entre les zones de filtration (152') et de l'élément de démoussage (152") et le volume du réservoir (10), ce dernier ne nécessitant qu'un volume essentiel de fluide de traitement. Les admissions du fluide de cardiotomie et du sang veineux dans l'appareil peuvent être rotatives, vues en plan, indépendamment l'une de l'autre et du corps (12) du réservoir (10).

Granted: 2007-05-29
Abstract: Systems and methods of increasing the performance of computer networks (208), especially networks connecting users to the Web, are provided. Performance is increased by reducing the latency the client (252) experiences between sending a request to the server (256) and receiving a response. A connection cache may be maintained by an agent (260) on the network access equipment (254) to more quickly respond to request for network connections to the server (256). Additionally, the agent may maintian a cache of information to more quickly respond to requests to get an object if it has been modified. These enhancements and other described herein may be implemented singly or in conjunction to reduce the latency involved in sending the requests to the server by saving round-trip times between computer network components.

Abstract: A hermetic rotary compressor assembly having a housing, a cylinder block and a bearing assembly within the housing. The cylinder block and the bearing assembly define a cylindrical cavity which has a roller piston disposed therein. The rotary compressor assembly includes a motor drivingly coupled to the roller piston and the cylinder block has a vane slot extending completely axially through and extending radially from an outside perimeter surface of the cylinder block to the cylindrical cavity. At least a portion of the vane slot is defined by a pair of substantially parallel sidewalk and a vane is disposed in and guided by the vane slot and is urged against said roller piston. The cylinder block is fixed in a state of circumferentially oriented stress. A method to assemble the rotary compressor includes spreading apart the sidewalls of the vane slot in the cylinder block, inserting into the spread apart slot a gauge vane of thickness greater than the thickness of a reciprocating vane, releasing the block to cause the slot sidewalls to engage the gauge vane, fixing the cylinder block to hold the engaged sidewalls, removing the gauge vane from the slot, and inserting the reciprocating vane in the slot, whereby a clearance is maintained between the reciprocating vane and slot sidewalls. Another method includes closing together sidewalls of the vane slot to engage the gauge vane, fixing the cylinder block to hold the engaged sidewalk, removing the gauge vane from the slot, and inserting the reciprocating vane in the slot.

Abstract: A windshield wiper system for an automotive vehicle is disclosed in which the windshield wiper washer fluid is heated and delivered to the windshield through the rubber wiping element. In one embodiment, the windshield wiper fluid is heated to a substantial level of temperature and pressure within a sealed reservoir by the heat from the engine coolant system. In another embodiment, a tubular electrical high intensity heating element with turbulent counter flow is used to instantly heat the windshield wiper fluid, and the heating element is automatically electrically energized in response to fluid flow through the tubular heating element.  In another embodiment electrical direct current vehicle power or selectively alternating current external power is used to heat fluid to a substantial level of temperature and pressure within a sealed insulated reservoir. A novel windshield wiper blade is also disclosed in which the wiper blade has a longitudinally elongated fluid chamber formed along its length. The fluid chamber is closed at one end and connected to the source of the washer fluid at its other end. A  plurality of longitudinally aligned slits is formed through the wiper blade to the outlet edge to uniformly dispense the heated washing fluid downstream of wipe direction, and onto the vehicle windshield while one or more openings are also formed in the wiper blade to direct a portion of the heated washing fluid to the joints in the wiper support frame to remove ice binding the wiper frame flex joints.  Additionally, the dual configuration of the blade edge is such that the second edge pair wears out sequentially to the first edge pair effectively doubling the clean wiping life of the blade.

Abstract: In order to effectively terminate a burst transmission in a wireless system, a method and apparatus determines whether or not a burst transmission from a wireless unit to a base station should be terminated by evaluating at least one criterion related to the operation of the wireless system. Once it is determined that a burst transmission should be terminated, the transmission is terminated by lowering a target signal -to-noise ratio (SIR) by a predetermined amount. By lowering this target SIR, power control bits transmitted from the base station to the wireless unit instruct an extreme decrease in power of the burst transmission and. quickly act to terminate the burst transmission.

Title: Gas conversion using synthesis gas produced hydrogen for catalyst rejuvenation and hydrocarbon conversion
Inventor: DENTON ROBERT DEAN
IPC: C07B61/00
Filed: 1999-02-05
Granted: 2007-01-02
Abstract: A gas conversion process in which both hycdrocarbons and hydrogen are produced from a synthesis gas feed which comprises a mixture of H2 and CO, uses hydrogen from a portion of the feed for one or more of (i) hydrocarbon synthesis catalyst rejuvenation and (ii) hydroconversion upgrading of at least a portion of the synthesized hydrocarbons. Hydrogen is produced from a slipstream of the synthesis gas fed into the hydrocarbon synthesis reactor by one or more of (i) physical separation means such as pressure swing adsorption and (ii) chemical means such as a water gas shift reactor. If a shift reactor is used due to insufficient capacity of the synthesis gas generator, physical separation means such as pressure swing adsorption will still be used to separate a pure stream of hydrogen from the shift reactor gas effluent.
