Patent CA-2437576-A1 (CA)
Title: Method for evaluating therapeutic efficacy
Inventor: DILLON SUSAN
IPC: C12N5/08
Filed: 2002-02-15
Abstract: The present invention relates to in vitro methods for evaluating compounds that better correlate with therapeutic efficiency than evaluating compounds based on potency alone. In general, the inventive methods comprises: (i) determining a potency value for a compound against its target receptor; (ii) determining a potency value for a compound against its target receptor; and (iii) comparing the potency value wit the desensitization value. If the desired action of a compound is as a receptor agonist, the compound's desensitization value should be larger than the compound's potency value. Th is ensures that the concentration of a compound required for potency will not also cause the receptor to desensitize at the same time, thus in an essence nullifying the desired effect. The inventive methods are used to evaluate novel motilide compounds as well as ABT-229 and EM-574, two motilide compoun ds for which clinical trials have been initiated.

Title: Bridge apparatus and bridge method
Inventor: KOBAYASHI YOSHIKAZU
IPC: H04L47/2416
Filed: 2003-08-28
Abstract: Disclosed is a bridge apparatus for the relay of a frame between a wire LAN and a wireless LAN. When a frame transmitted by the wire LAN is a specific frame, a QoS middleware unit of the bridge apparatus adds a bridging request to an FIFO queue having a high priority. And when the frame received from the wire LAN is not a specific frame, the QoS middleware unit adds a bridging request to an FIFO queue having a low priority. A bridging unit performs the priority processing for the bridging request present in the FIFO queue having a high priority, and transmits the frame to the wireless LAN.

Inventor: WENZEL KENNETH H
IPC: F16C33/72
Filed: 2004-01-21
Abstract: A method of reducing wear on a backup seal sealing a bearing chamber of a downhole tool. The method involves providing either the first sealing assembly, the second sealing assembly, or both with a floating piston which moves axially in the bearing chamber in response to changes in pressure. Movement of the floating piston determines positioning of one or more backup seals. Either the exterior surface of the rotating shaft or the floating piston is provided with an undercut, which provides a clearance space between the backup seal and the exterior surface of the rotating shaft. The backup seal does not engage the exterior surface of the rotating shaft until axial movement of the floating piston occurs to move the backup seal out of the undercut and into engagement with the exterior surface of the rotating shaft.

Title: Drill bit and cutter having insert clusters and method of manufacture
Inventor: BUFORD ERNEST L
IPC: E21B10/52
Filed: 2004-02-20
Abstract: Disclosed is a rolling cone cutter and drill bit employing multiple inserts retained as a cluster in an aperture in the cone cutter. Apertures in which the insert clusters are retained are multilobed apertures formed by intersecting bores formed in the cone steel. The apertures may also be created by forming spaced apart bores and milling regions of the cone steel that extends between the bores. The inserts in a cluster may be retained within the aperture to differing depths, may extend above the cone steel to differing extension lengths, and may have cutting portions having a variety of shapes. The inserts in a cluster may be made of different materials in order to optimize cutting duty. The bores forming the multilobed aperture may be parallel or skewed, and may create an aperture having a multilevel bottom surface so as to permit the insertion of an insert having a relatively large cutting surface in instances when the cone design would not otherwise permit the use of a cylindrical insert of the desired diameter.
