Patent CA-2397115-A1 (CA)
Inventor: BURT RICHARD A
IPC: G01V3/20
Filed: 2001-01-10
Abstract: An apparatus for obtaining resistivity images of a borehole includes an array of measure electrodes separated from a pad or the body of the instrument by a guard electrode. The guard electrode is maintained at a slightly lower potential than the pad and the measure electrode is at an intermediate potential thereto. With this arrangement, the current from the guard electrode defocuses the measure current from the measure electrode as it enters the formation, and at greater distances, the current from the measure electrode is refocused by the effect of the current from the pad. This defocusing and refocusing defines a region of investigation away from the borehole wall that is relatively insensitive to borehole rugosity. Circumferential and vertical overlap may be obtained either by the arrangement of the measure electrodes, or by relying on the broadening of the measure beam as it enters the formation.

Title: Method and position control for a servo system for positioning a head laterally with respect to defined servo tracks
Inventor: KOSKI JOHN ALEXANDER
IPC: G11B21/10
Filed: 2001-07-06
Abstract: A method and position control for a servo system for positioning a head laterally with respect to defined servo tracks. The servo system comprises a servo sensor and detector (115) for sensing lateral position of the head (15) and a compound actuator (14) having a fine actuator portion (20) and a coarse actuator portion (16). The position control (116) provides position indications for the coarse actuator portion (16), which may comprise a table relating predetermined nominal lateral position indications to the defined servo tracks. The position control (116) positions the coarse actuator portion (16) at an estimated position with respect to the defined servo tracks, and responds to the servo sensor to determine which servo track is closest to the estimated position. The position control (116) sets the coarse actuator portion (16) position indication to the predetermined nominal lateral position indication of the closest defined servo track, e.g., by looking it up in the table. This thereby corrects the indication of the position of the coarse actuator portion (16).

Title: Vaccins a base d'acide sialique modifie
Inventor: JENNINGS HAROLD J
IPC: A61P35/00
Filed: 2001-07-26
Abstract: Le constituant acide sialique d'un marqueur de surface cellulaire contenant des unités d'acide sialique caractéristique de cellules mammaliennes cancéreuses est modifié de manière que les cellules exprimant normalement ce marqueur expriment au lieu de cela un marqueur de surface cellulaire contenant des unités d'acide sialique modifié qui est fortement immunogène. Par exemple, la présente invention permet, dans une certaine quantité de cellules du patient qui expriment régulièrement GD3 (soit différents types de cellules cancéreuses), l'expression d'un antigène de surface fortement immunogène, à savoir GD3 dans lequel les restes d'acide sialique sont modifiés. Ladite modification est avantageusement la N-acylation d'un précurseur de l'acide sialique, si bien que le précurseur N-acylé est chimiquement incorporé dans l'acide sialique pendant sa synthèse biochimique intracellulaire. Des anticorps spécifiques de l'antigène modifié, qui peuvent être induits à l'aide d'un conjugué d'une quantité adaptée du marqueur contenant les unités d'acide sialique modifié et d'un véhicule, peuvent ensuite être utilisés pour éliminer les cellules qui expriment GD3 modifié. Des vaccins peuvent être préparés à l'aide de conjugués du marqueur contenant l'acide sialique modifié, ou à l'aide d'anticorps produits en réponse à l'exposition d'un sujet approprié au marqueur contenant l'acide sialique modifié, pour traiter des états pathologiques cancéreux qui impliquent des cellules cancéreuses caractérisées, au moins en partie, par l'expression du marqueur contenant les unités d'acide sialique modifié.
Patent CA-2420109-A1 (CA)
Inventor: ROBINSON KEITH D
IPC: F24F13/04
Filed: 2003-02-18
Abstract: A fixed blade air mixing apparatus includes a plurality of radially extending vanes which extend away from a common center and terminate at their outer ends within a polygonal shaped shroud. The plurality of vanes include an inner section which is curved or pitched in one direction, and an outer section which is curved or pitched in a second direction away from the inner section, the inner and outer sections sharing a common leading edge. The apparatus is intended for use in eliminating stratification of airstreams of different temperatures flowing through a common passage, for example, in heating, air conditioning, or other ventilating ducts. The vanes are designed to establish downstream turbulence of the airstreams passing therethrough which produces optimum mixing effectiveness and a uniform velocity profile of the air downstream of the mixing apparatus with a minimum pressure drop as the air flows through the apparatus.

Title: Managing replacement of data in a cache on a node based on caches of other nodes
Inventor: BROWER DAVID
IPC: G06F12/08
Filed: 2001-08-30
Abstract: Caches on nodes in a cluster are globally managed so that a data item may be retained in any of the caches. A replacement policy that governs the replacement of data items stored in the caches selects buffers for replacement according to factors that include the state of the caches of other nodes. Some cached data items are designated as globally shared and assigned a primary cache. If a buffer holds a copy of a data item whose primary cache is another node, then the data item in the buffer is favored for replacement over a local data item or a global data item for which this is the primary cache. Cache retention values of buffers on different nodes may be compared. The buffer with the lowest cache retention value is selected for replacement. The replacement policy may also account for the way other caches in the cluster are configured.

Title: Conveyor personnel gate
Inventor: FRANK JAMES L
IPC: B66B29/08
Filed: 2001-10-26
Abstract: A freestanding conveyor personnel gate includes a support or base portion and a conveyor portion, which is pivotable and movable relative to the support between a closed position and an open position. The gate includes a latch mechanism which is operable to latch the gate in both the open and close positions. The latch mechanism is operable via a handle which is movable in either direction to disengage the latch mechanism and to raise or lower the conveyor portion toward its open or closed position. The conveyor portion is balanced and supported via a strut member which is pivotally mounted at the conveyor portion and the support portion. A biasing member is provided to bias the conveyor portion toward its closed position when the conveyor portion is moved past a neutral point between the open and close position. The biasing member is further operable to bias the conveyor portion toward its opened position when the conveyor portion is moved past the neutral position toward the open position of the gate. The biasing member thus self propels the gate toward its opened or closed position, while the latch mechanism locks the gate in the respective position once that position is reached by the conveyor portion.
