Patent CA-2433793-A1 (CA)
Inventor: ROSENBLUTH ROBERT F
IPC: A61B17/00
Filed: 2001-01-09
Abstract: Cathéters d'embolectomie (10, 10', 10'', 10''', 10''''), microcathéters à échange rapide, systèmes et procédés pour évacuer les caillots ou d'autres matières obstructives telles que les thrombus, les substances thromboemboliques, les fragments emboliques de la plaque d'athérosclérose, les corps étrangers, etc. L'invention peut notamment s'utiliser pour l'évacuation percutanée des substances thromboemboliques ou d'autres matières obstructives à partir de petits vaisseaux sanguins du cerveau à la suite d'un accident cerébro-vasculaire en évolution ou d'une période d'ischémie cérébrale. Dans certains modes de réalisation, les cathéters d'embolectomie comprennent des dispositifs de récupération de caillots qui peuvent se déployer à partir du cathéter une fois que celui-ci a été déplacé, au moins partiellement. à travers le caillot. Le dispositif d'évacuation de caillots comprend un nid en fils à capacité de déploiement (14), conçu de manière à ce que les caillots ne puissent pas le traverser. Le cathéter d'acheminement peut comprendre des tubes télescopiques interne et externe, le dispositif d'évacuation de caillots étant radialement limité par le tube externe. Le retrait du tube extérieur a pour effet d'enlever la contrainte exercée sur le dispositif de récupération de caillots et lui permet de se déployer pour se mettre en configuration déployée. Un fil de guidage de perfusion est particulièrement utilisé conjointement avec le cathéter d'embolectomie; il permet de perfuser des médicaments ou des liquides de visualisation à une certaine distance du caillot.

Title: Bottle and closure
Inventor: ZIEGENHORN DAVID
IPC: B29C49/00
Filed: 2002-02-12
Abstract: There are various ways to latch a closure onto a container. It has been foun d that for blowmolded containers (30) that the support flange (36) for the bottle preform can later be used as a part of the latch mechanism (14) to secure a closure (10) onto the container. Preforms have a support flange by which the preform is handled prior to being placed into the mold and in the mold. Prior to being placed in the mold, the preform is heated to about 85 ~ C to about 200 ~C. During this time and in the mold, it will be supported by t he support flange. This support flange is used after the container is blown and filled as one part of the latching mechanism of the closure. The closure wil l have a portion that is an interference fit with the support flange of the bottle to thereby secure the closure to the bottle.

Title: Automatic priming system
Inventor: CARPENTER TODD L
IPC: F02M1/16
Filed: 2003-09-17
Abstract: An automatic priming system for internal combustion engines, which is operable at engine cranking speeds and which is automatically disabled at engine running speeds. The automatic priming system is driven by pressure fluctuations within the engine crankcase which are caused by reciprocation of the piston. At engine cranking speeds, fluid communication between the engine crankcase and a chamber is substantially equalized, such that positive pressure pulses from the crankcase air space pass from the chamber through a check valve to the carburetor for priming. At engine running speeds, communication between the crankcase air space and the chamber is restricted such that the pressure within the chamber is below atmospheric, positive pressure pulses are not present within the chamber, and the priming function is automatically disabled.

Abstract: An improvement in damping vibrations in the cables of cable stayed bridges involves the provision of one or more viscous damping elements within the space between the cable and a surrounding stay tube. The direction of action of the damping element(s) is generally parallel to the longitudinal axis of the cable. In one embodiment a toggle mechanism is provided at each end of a viscous damping element to connect the element to both the stay tube and the cable. Each toggle mechanism is pivotally connected to the viscous damping element as well as to the stay tube and cable so that transverse vibrations occurring in the cable are transmitted via the toggle mechanism to the viscous damping element so as to effectively dampen such vibrations. In a typical scenario the viscous damping element will be a piston and cylinder arrangement with a viscous fluid retained within the cylinder, similar to an automotive shock absorber.
