Patent CA-2439501-A1 (CA)
Inventor: SMITH DARRELL M
IPC: B32B21/04
Filed: 2002-03-08
Abstract: A molded wood composite article man-made from wood fibers or wood particles on at least an upper, molded surface of the article, and a method of manufacturing the article to include a relatively uniform density, detailed design contours and textured aesthetics on one or more molded depression- interior inclined surfaces, while preventing embrittlement, softness and blistering of the article along the depression-interior inclined surfaces. These attributes are achieved by molding one or more depressions into an initially planar layer of cellulosic material, wherein the molded depression s have a length to depth ratio in the range of about 5.0 to about 8.5, and hav e one or more inclined walls that have upper surfaces, along essentially an entire inclined span, that include detailed design contours, including adjacent curved and planar portions, e.g., bead and cove. The inclined depression-interior molded walls, having upper surfaces that include the adjacent curved and planar contours, have a thickness or caliper measurement , measured normal to a tangent at any point along the upper (finished) contour ed surface, that is smaller than the caliper so measured at horizontal, distal ends that are integral with the depression-interior contoured, inclined surface span, to make sure that the inclinedsurfaces of adjacent, stacked articles do not contact each other during shipping.

Title: Improvements in fluid measurements in a reaction vessel used in conjunction with a clinical analyzer
Inventor: BOWER RANDY K
IPC: G01F23/00
Filed: 2003-10-01
Abstract: A method for measuring the amount of fluid contained in a reaction vessel in a clinical analyzer includes the steps of adding a first aliquot of fluid to the reaction vessel and measuring the quantity of fluid contained therein. A second aliquot of fluid is then added to the reaction vessel and the quantity of fluid contained therein is also measured. Measurement of the two fluid quantities can occur with or without removal of the first aliquot in between measurements. In obtaining the two quantity measurements and comparing them against a standard, the effects of well geometry can be minimized. Preferably, a delta or ratio measurement is obtained between the first and second liquid volume measurements which can be compared against a standard so as to normalize apparent volume losses or gains due to reaction well dimensional variation. This approach enhances the analytical capability to detect true fluid delivery errors.

Title: Multiple-part fast cure powder coatings
Inventor: HORINKA PAUL R
IPC: C09D163/00
Filed: 2004-05-03
Abstract: The present invention provides a powder composition in multiple separate parts comprising one or more than one resinous powder component in one or more than one part and, for each resin component, one or more than one powder, liquid or gaseous curing agent component in one or more than one separate part, wherein the average particle size ratio of each resinous powder component to its curing agent powder or droplet component ranges from 1.3:1 to 60:1 to insure the attraction of the resin and its curing agent to one another. Useful resins may include epoxy resin, polyester resin or their combination. The shelf life of the powder composition can be extended indefinitely by storing each resin and its curing agent in separate parts. However, each resin and its curing agent react within a period of from 0.01 to seconds to form a cured powder coating when combined at a temperature of from 20°C and 200°C to enable very low temperature cure. In addition, the present invention provides a method of forming a powder coating from the inventive composition which comprises combining each of the separate parts in stream while or by applying them to a substrate, for example, as two or more than two separate feed streams from a single applicator device, followed by curing.

Patent CA-2485386-A1 (CA)
Inventor: MORRISON DENBY GREY
IPC: E21B19/00
Filed: 2003-05-28
Abstract: The invention describes a cost-effective alternative for deploying and installing subsea equipment (80) using a workboat or other vessel of opportunity (20). The equipment is not supported directly by the vessel, but is instead supported by one or more buoys (110, 160) below the wave zone. The buoys are controlled by a combination of chain (130), wire rope (140), and synthetic line (120, 170) linking it to the workboat. As such, the buoy system described herein decouples vessel motion from the payload by supporting the payload from the buoys below the wave zone. Because the buoys are below the wave action and its associated turbulence, there is little energy and hence little tendency for motion. The result is a stable, inexpensive, maneuverable system capable of servicing large subsea payloads in a wide range of water depths.

On détermine ensuite l'emplacement du point superficiel du premier réseau que l'on utilise pour mesurer la distance normale, l'emplacement déterminé servant ensuite à localiser le même point superficiel sur le second réseau. On détermine alors un nouvel emplacement pour un nouveau point correspondant au point sur le modèle du trait associé au premier réseau. On localise le nouvel emplacement à la distance de la distance normale déterminée, mais le long d'un vecteur normal qui croise le même point superficiel sur le second réseau.

Title: Timer-based feedback in multicast communication
Inventor: NEKOVEE MAZIAR
IPC: H04L12/18
Filed: 2003-06-12
Abstract: A multicast system is described in which a mechanism for suppressing feedback involves the receivers using an optimized timer function for selecting a backoff delay time before sending feedback, and canceling their feedback if in the meantime they detect that another receiver has sent a duplicate feedback message. The timer function is optimised, taking into account both the expected number of feedback messages and the extra latency which is introduced by the feedback mechanism, by minimizing an objective function expressed in terms of both these two aspects

Abstract: A retrievable drill pipe screen is adapted for releasable connection within a drill pipe string. The screen has a planar support plate for connecting a perforated tubular screen body to a fish neck wherein the plane of the planar support plate is generally parallel to the axis of the screen body. The orientation of the planar support plate provides minimal resistance to fluid flowing into the screen body while also reducing vortex effects that cause wear of screen components. Preferably, a wear distributor sleeve is fit within the screen body for protecting against wear of the screen caused by fluid flow and a retaining rod can secure the bottom of the screen body to the fish neck in the event that a lower portion of the screen body becomes detached.

Title: System and related methods for sensing forces on a movable barrier
Inventor: BENNETT THOMAS B III
IPC: E05F15/00
Filed: 2003-07-25
Abstract: An operator system and related methods (10) for sensing forces on a movable barrier (12) includes a motor (52), a trolley (30), and a trolley arm (34) having a first end slidably supported by the trolley (38) and a second end coupled to the movable barrier. The motor moves the trolley arm which in turn moves the movable barrier. A force detection mechanism (68) is coupled to the motor to determine a first component force value applied by the motor. A  controller (54) receives the first component force value and determines a detected force value by scaling the first component force value with a second component force value derived from an angular position of the trolley arm's first end with respect to the trolley. The angular position of the trolley arm may be fixed or variable. An angle potentiometer (72) is coupled to the trolley arm to generate an angle signal for use as the second component force value when the trolley arm's angular position is allowed to vary.
