Patent CA-2240226-C (CA)
Inventor: WALL WESLEY JAMES
IPC: B65D51/00
Filed: 1998-06-10
Granted: 2009-03-24
Abstract: A method of impregnating a polymer plastic plug with wood preservative. A first step involves dehydrating a polymer plastic plug to reduce its naturally occurring moisture content. A second step involves introducing liquid wood preservative into the polymer plastic plug while the polymer plastic plug is in a dehydrated state by immersing it in the liquid wood preservative and boiling the liquid wood preservative at temperatures that are less than that required to turn the polymer plastic plug into a molten state. In accordance with the teachings of this method liquid wood preservative is absorbed into the dehydrated polymer plastic plug in place of the naturally occurring moisture content.

Title: Caching dynamic webpages
Inventor: KUPERMAN LEON
IPC: G06F17/30
Filed: 1998-06-12
Granted: 2002-04-30
Abstract: Web pages for commercial applications, such as electronic retail, are built "on-the-fly" in Hypertext Markup Language (HTML) from product data stored in the merchant's database. To reduce costs in time and computing resources and to improve customer access to data from the merchant's web site, pages created in HTML are cached on the merchant server.  On a customer request for a page, the merchant server checks the cache first for the page, and if it isn't found there, generates a new page from the database. To maintain the validity of the content of the cached pages, the database tables include triggers that cause identifying information for any changes made on the stored data to be forwarded to a cache log. A  synchronization daemon walks the cache log from time to time to locate pages that should be purged from the cache because their content is no longer synchronous with the data stored in the database. By setting preferences for identifiable customers in advance, data generated from the database can be selected for specific customer groups.

Title: Process and apparatus for removing odor from animal confinement buildings
Inventor: POTEAT JERE
IPC: A61L9/12
Filed: 1998-12-16
Granted: 2007-06-05
Abstract: Apparatus and methods for removing odor from the air exhaust of animal confinement buildings are described. One embodiment of the apparatus includes a plenum housing attached to an existing exhaust fan on an animal confinement building. The plenum housing has an entrance and an exit, and houses a baffle having a roughened surface. Water is delivered to the baffle surface by spray headers which are configured to spray water from a top edge of the baffle. A water curtain is generated by spray nozzles at the plenum housing exit. A trough is configured to collect a water effluent from a bottom edge of the baffle. In use and according to the methods described, an air stream consisting of exhaust air from an animal confinement building is directed toward the water- flooded baffle surface. Odor particles in the air stream impinge on the baffle surface and are adsorbed by the water. The air stream continues to flow past the baffle surface and through the water screen at the plenum housing exit. Additional odor particles and water soluble gases are absorbed and adsorbed by the water screen. Droplets from the water screen fall to the baffle surface and are collected with the effluent. The effluent is drained away directly to a lagoon or to a primary waste water treatment facility for treatment to remove odor particles and gasses.

Abstract: A self sealing valve includes a diaphragm (602) positioned within a valve housing (606) by a movable hanger arm (610) which suspends the diaphragm from a mounting point (612) in the center of an air inlet (614). The hanger arm (610) is a rotating diaphragm hanger that has one end secured adjacent to an inner wall (618) of the air inlet (614) by a pair of pins (634). There is a contoured section (648) between the hinge pins (634) of the inner wall which interfaces with a contoured end (650) to provide for at least four distinct interaction possibilities. A first retains the hanger arm (610) in a valve closed position. A second causes the valve to exhibit a biased closed condition. A third locks the valve open and a fourth facilitates assembly.</ SDOAB>

Title: Hydraulic elevator with plunger brakes
Inventor: SEGGEBRUCH ERNIE
IPC: F16D65/22
Filed: 1999-04-23
Granted: 2006-08-22
Abstract: A brake for a plunger of a hydraulic elevator is provided which in a preferred embodiment includes a pressure plate, a first brake ring, a wedge plate, a biasing spring and a fluid release actuator. The pressure plate is movable along an axis generally parallel with the axis of the plunger. The first brake ring encircles the plunger and has an inner surface for engagement with the plunger. The fast brake ring also has a second surface for force engagement with the pressure plate. The first brake ring additionally has an outer wedge surface. The first wedge plate has a first wedge surface for engagement with the wedge surface of the first brake ring. The spring biases the pressure plate and wedge plate toward one another. The fluid release actuator urges the pressure plate away from the wedge plate.  Upon release of the actuator relative movement of the pressure plate towards the first wedge plate causes the brake ring to circumferentially grip the plunger and prevent movement axial of the plunger.
Patent CA-2271334-C (CA)
Inventor: RUBBRIGHT HARRY A
IPC: A23L23/10
Filed: 1999-05-07
Granted: 2002-10-01
Abstract: A container for microwave cooking having geometric features which improve the efficiency and uniformity of microwave cooking of food products containing liquids and which enhance boiling uniformity while preventing boilover of the contents. The container has a bottom portion and a side panel wherein the bottom portion contains a central segment in the shape of a section of a sphere.     The side panel is tapered outwardly as it extends from the bottom portion to an end opening. Sharp corners are avoided within the container. As the result of the geometry of the container, a more uniform distribution of heat within the contents of the container is attained during cooking and the combination of uniform heating, the lack of sharp corners and the tapered side panel causes boiling of the contents without bumping, thereby minimizing the risk of boil over.

Abstract: A checksum is extracted from an image downloaded to a content recipient. The content recipient transmits the extracted checksum to a data collection site. The data collection site compares the received checksum to a refer-ence checksum. If the received checksum and the reference checksum match, the data collection site uses an image corresponding to the reference checksum as the downloaded image. If the received checksum and the reference checksum do not match, the data collection site retrieves the down-loaded image from the content recipient.

Abstract: La présente invention concerne un procédé d'affichage de données de guide électronique de programme (EPG) dans un format essentiellement en forme de grille, sans utiliser les informations de "chaînes" comme axe. Plus particulièrement, au lieu d'être présentées par canal et par heure, les données EPG sont uniquement présentées par heure. En outre, divers algorithmes de troncature sont utilisés pour raccourcir les descriptions de programmes, ce qui permet de placer ces descriptions dans les espaces ou les cellules vides d'une rangée disponible. Ainsi, on peut afficher les informations des programmes de différentes chaînes dans une seule rangée, et améliorer de ce fait l'efficacité d'emploi de l'espace d'affichage.
