Patent CA-2172309-A1 (CA)
Inventor: KRUPKE LEROY GREGORY
IPC: E06B9/58
Filed: 1996-03-21
Abstract: A flexible roll-up door assembly includes opposed, elongated frame members supporting guides for longitudinal side edges of the door and for slide members connectable to a bottom beam of the door closure member by a latch mechanism which includes opposed latch members which engage the slide members, respectively. The slide members rotate to permit the latch members to separate in response to a predetermined force acting on the door closure or the bottom beam. The latch members are spring biased to retract out of or extend into cooperating slots in the slide members and may be reinserted in the slide members to reconnect the door to the guides. The latch members may include retaining projections cooperable with reentrant edges or other surfaces in the slots to retain the latch members engaged with the slide members. Alternate embodiments include latch members formed on the slide members and engaged in slots formed in a transverse bottom beam for the door closure member. Spaced apart tensioning reels are mounted on the door closure shaft and support cables which are trained through the guides and are connected to the slide members to apply a pulldown tensioning force on the door closure member. Pivotable brake arms, disposed adjacent the tensioning reels, have the tensioning cables trained thereover and are responsive to disconnection of the door bottom beam from the slide members to engage the tensioning reels to reduce the speed of cable windup.
Patent CA-2174367-A1 (CA)
Title: Turbine cooling cycle
Inventor: GLEZER BORIS
IPC: F02C7/141
Filed: 1996-04-17
Abstract: Air flow delivery systems for gas turbine engines are used to increase component life and increase power and efficiencies.  The present system increases the component life and increases efficiencies by directing a portion of a compressed air formed by the compressor section and located in a first fluid flow path to a second fluid flow path including a heat exchanger positioned operatively within the second flow path.  The second fluid flow path results in a flow of cooled cooling air to be directed to the components of the gas turbine engine to be cooled.  Thus, the components of the gas turbine engine are more efficiently cooled with a smaller quantity of air drawn from the compressor section generated air than if compressor generated air was used for cooling components of the gas turbine engine. Furthermore, more compressor generated air remains for combustion within the combustor section of the gas turbine engine.

Les informations d'image qui ont été traitées dans l'unité de traitement d'image sont stockées dans un support de stockage par une unité d'écriture d'image (1500). Lorsqu'on introduit dans une machine de jeu le support de stockage sur lequel sont enregistrées les informations d'image, ces dernières sont lues par l'unité de lecture de la machine de jeu. Dans l'unité d'exécution du jeu de la machine de jeu, un jeu préprogrammé est exécuté en fonction des informations d'image du jeu stockées dans une unité de stockage de jeu. Une unité de commande d'affichage exécute la commande d'affichage sur les informations d'image lues sur le support de stockage au lieu de lire une structure d'image particulière, ces informations d'image faisant partie des informations d'image stockées dans l'unité de stockage d'images de jeu. Par exemple, les traits d'un joueur entrés à la place d'une structure d'image particulière peuvent être affichés si l'on entre ces traits comme informations d'image.

Patent CA-2185494-A1 (CA)
Inventor: GRIMARD JEAN-PIERRE
IPC: A61J1/20
Filed: 1996-09-13
Abstract: A resealable vial featuring a connector assembly having a membrane and a pusher for selectively opening or sealing the fluid passageway between the bottle and the connector end of a luer hub. The connector assembly includes a body disposed on said bottle, and means for communicating fluid such as a luer connector hub which may be separately provided with the body or formed integrally therewith. The luer connector hub features a connector end open for access by medical delivery instrument, and an opposed end which is disposed for fluid communication with a recess defined by the body. The body defines a recess having a fluid path with the open top of the bottle. A membrane, preferably formed from an elastomeric material, is secured across both the recess and the open top of the bottle, and may be retained between the top surface of the bottle and the body. The membrane preferably includes a central area sealing the recess from the open top of the bottle, with one or more fluid openings defined on a portion of the membrane outside of the central area. A pusher is located in the recess. A force exerted on the pusher deflects the membrane towards the interior of the vial, urging the membrane and fluid openings away from the body to open the fluid path between the bottle and the recess. The pusher may be structured to include one or more fluid pathways so as to facilitate fluid flow through the recess. A sealing rib may be provided around the portion of the periphery of the recess to enhance sealing contact between the central area of the membrane and the recess.

Patent CA-2188532-A1 (CA)
Inventor: SCHROEDER WOLFGANG
IPC: G05D7/06
Filed: 1996-02-20
Abstract: A process is disclosed for adjusting the filling stream of automatic feeding flow-controlled filling machines. The object of the invention is to supply a medium volume in a uniform and clean manner to the container through the filling pipe. For that purpose, the speed of a filling stream ejected by the filling pipe is determined and stored as a set value. The real value of the speed of volume leaving the pump is measured by a speed sensor and the thus obtained values are compared in order to adjust the speed of the ejected filling stream. The capacity of the pump is modified until the stored value of the filling stream speed at the volume sensor matches the speed of the medium volume measured at the speed sensor. Only then the vessel filling process is started.
