Patent CA-2266872-A1 (CA)
Inventor: STEWART WILLIAM MCMURRARY
IPC: F16F9/00
Filed: 1999-03-25
Abstract: Method of stabilizing valve lift-off movement in an automotive hydraulic shock absorber having compression and expansion chambers filled with a hydraulic shock-absorber fluid and divided by a valve body with one or more orifices that have fluid flow therethrought controlled by a spring biased valve that lifts off from the valve body when the fluid pressure differential between chambers is above a predetermined amount. The steps of the method comprise (a) stationing the spring biased valve with respect to the orifices so that the fluid forcing the valve to lift off and overcome the spring bias will exit from the orifices in a manner that creates a velocity gradient in the expansion chamber resulting in pressure differences that disturb a smooth lift-off of the valves; and (b) modifying the hydraulic shock absorber fluid to form a mixture containing fumed amorphous silica whereby the fluid mixture will possess a viscosity inversely proportional to the velocity of the fluid mixture regions, the mixture will achieve the needed hydraulic attenuation.

Abstract: Cette invention concerne une attache chirurgicale (10) se présentant sous forme d'une boucle à virole (14), ainsi qu'un instrument et un procédé permettant d'effectuer une greffe sur une anastomose artérielle ou sur des anastomoses d'autres tissus mous, ceci selon une procédure chirurgicale à invasion minime ou endoscopique. Cette attache de type boucle à virole comprend une aiguille (12), une suture (16) et une virole (14). L'aiguille et l'élément suture permettent, par exemple, de coudre l'attache à travers la greffe et l'artère que l'on veut joindre. L'élément virole permet de former la boucle de type virole sans qu'il soit nécessaire de nouer l'élément suture de manière à ce que ce dernier puisse jouer le rôle de point de suture et permette de fixer la greffe et l'artère l'une à l'autre. L'aiguille et la virole sont montées sur l'extrémité distale de l'instrument. Des commandes situées dans une poignée permettent de manipuler l'aiguille et d'appliquer l'attache de manière contrôlée. Le procédé décrit dans cette invention fait appel à la boucle de type virole ainsi qu'à des instruments afin de joindre des tissus mous et d'effectuer des greffes sur des anastomoses artérielles.

Patent CA-2282037-A1 (CA)
Title: Valve control system
Inventor: MUNSHI SANDEEP
IPC: F16K31/365
Filed: 1999-09-13
Abstract: A fluid control valve has a valve member which, on closing creates a stagnation zone between the valve member and a surface within the valve. In the stagnation zone fluid pressure is greater than it is in an adjacent constriction zone. This causes the valve to close slowly, thereby reducing the likelihood that water hammer will occur on closure of the valve. The design of the valve member also reduces resonances which can cause annoying noises and premature wear. A flow restriction chamber further slows closure of the valve. The fluid control valve may be controlled by a conventional 3-way pilot valve. Preferably the fluid control valve is used with a pilot valve according to the invention having a rocker member which, on actuation, first closes an inlet valve member and then opens an outlet valve member. The pilot valve may be used in other situations where a 3-way valve is needed.
