Patent CA-2320077-A1 (CA)
Title: Swivel seal assembly
Inventor: DIETLE LANNIE
IPC: E21B21/02
Filed: 1999-02-16
Abstract: A swivel seal assembly is defined for providing sealed high pressure fluid communication between relatively rotatable generally coaxial conduits (4, 6) where dynamic runout and static misalignment may occur to one conduit relative to the other. A generally tubular washpipe (66) is mounted in pivotally articulating relation to one conduit, and a generally tubular seal housing (40) is telescoped over the washpipe (66) and mounted in pivotally articulating relation to the other conduit. High pressure, staged rotary seals (41) are supported by the seal housing (40) and maintain bearing and sealing engagement with the washpipe (66) so that the seal housing (40) and washpipe (66) articulate in unison in response to static misalignment and dynamic runout, thereby virtually eliminating relative laterial motion between the seal housing (40) and washpipe (66) and minimizing rotary seal (41) extrusion damage. The seal housing (40) and washpipe (66) are hydraulic force balanced regardless of the pressure to which they are subjected, and thus are not subject to pressure induced loads which might otherwise interfere with articulation.

Title: Systeme de rotation de bille de bois en boucle fermee
Inventor: PERREAULT JEAN-PIERRE
IPC: B27B31/06
Filed: 2001-02-27
Abstract: 1.0 PROBLÉMATIQUE   La rentabilité financière et environnementale d'une usine de sciage dépend en bonne partie de la valeur ajoutée à la matière première qui est des billes d e bois. Il est donc important de maximiser le volume de produit transformé pour chaque bille. C'est ce que l'on nomme le rendement matière.  Pour ce faire, les systèmes de sciage actuels lisent la forme de chaque bill e à l'aide d'un scanner, ajustent les outils de coupe et tournent la bille à l'angle qui sera le plus favorable au rendement matière. Cependant, les imperfections de forme des billes (noeuds, trous, ovalité, etc.) limitent la précision de la rotation. Les pertes dues à cette imprécision peuvent varier  de 5% à 20% sur le rendement matière.

Title: Internet archive service providing persistent access to web resources
Inventor: ONG PING-WEN
IPC: G06F17/30
Filed: 2001-03-30
Abstract: An Internet archive service is disclosed that provides persistent access to Web resources. Time-stamped Uniform Resource Locators ("URLs") that identify Web resources are combined with URL redirect techniques to create an Internet archive service to make the Internet persistent. The present invention provides persistent Web access, without requiring all web servers to directly handle time-stamps in a URL. A user enters a dated URL, for example, using a web browser, which is transmitted to a web server. The Web server receives the URL (containing a time stamp, a relative time-stamp or a variable time-stamp), and retrieves the correct Web page(s) from its own archive, or redirects the user to a predefined Internet archive site. An archive finder may optionally be provided to identify the best Internet archive service where the desired resource has been archived. The Web server interprets the extracted URL in accordance with the selected time stamp format. The present invention ensures that a time-stamped reference to any Web resource refers to the desired material.
Patent CA-2344253-A1 (CA)
Title: Method and system for conducting electronic auctions
Inventor: ROBERTS FREDERICK W
IPC: G06Q30/06
Filed: 1999-09-17
Abstract: A method and system for conducting electronic auctions is described. A dynam ic lot closing extension feature avoids collisions in closing times of multiple  lots by dynamically extending the closing time of a subsequent lot if a preceding lot's closing time is extended to be too close to the subsequent lot's then-currently scheduled closing time. Scheduled closing times can be extended with a flexible overtime feature, in which the properties of the event triggering the extension and the duration of the overtime period(s) ca n be tailored to a particular auction, particular lots of products within an auction, and to the particular time within an auction process. The bidding status of a lot can be set to a "pending" status after the nominal closing time for submission of bids to allow bidders to alert the auction coordinato r of technical problems in submission of bids. This allows the possibility for  a lot to be returned to open status for further bidding by all bidders. The auction may be paused by the auction coordinator to correct technical, marke t and miscellaneous problems that may arise during the course of an auction. Individual bid ceilings can be set for each bidder so that they are required  to bid lower than certain thresholds determined in advance of the auction. Failsafe error detection is performed to prevent erroneous bids from enterin g the auction. The auction coordinator has the ability to override any erroneo us bids that are entered to prevent prejudice to the auction.

Patent CA-2350138-A1 (CA)
Inventor: SINK DANNY R
IPC: F16C33/76
Filed: 2001-06-08
Abstract: An improved unitized bearing seal assembly employs a resilient primary seal lip, a secondary seal lip and an excluder lip carried by a first seal case. The seal lips contact surfaces of a second seal case. One of the seal cases rotates relative to the other. The bearing seal assembly also includes a labyrinth seal positioned radially inboard of the resilient seal lips. The labyrinth seal has two axially-extending gaps. One of the axially extending gaps is defined by a resilient axial lip. The two axial gaps are joined by a radial gap. One of the surfaces defining the radial gap comprises chaplets with recessed surfaces between the chaplets. The chaplets include radially directed surfaces and inclined surfaces joining the radially directed surfaces with the recessed surfaces. These surfaces are shaped to provide hydrodynamic pumping action. A lubricant cavity is located between the labyrinth seal and the primary seal lip. The labyrinth seal restricts exchange of lubricant between the seal lubricant cavity and a lubricant-bearing cavity of a bearing element with which the seal is used. The three resilient seal lips limit ingress of contaminants into the seal cavity. The outermost excluder lip has an increased surface area in contact with the sealing surface of the second seal case.
