Title: A metering valve
Inventor: LAUBE DANIEL J
IPC: F16K21/16
Filed: 1989-12-13
Abstract: A metering valve is provided having a piston assembly mounted for movement between open and close modes.  The piston assembly is biased to assume a close mode.  The piston assembly assumes an open mode only when a predetermined external force is applied to a valve actuating element forming a component of the metering valve.  When the external force is removed, the piston assembly automatically returns to the close mode.  The rate of movement of the piston assembly during a first segment of travel from the open mode to the close mode is substantially slower than the rate of movement during a second segment of the travel.

Abstract: L'invention est constituée par un système et une méthode de mise à niveau d'un ordinateur. Certaines puces essentielles présentes dans l'ordinateur originel sont fonctionnellement éliminées du système informatique, sans toutefois être nécessairement extraites physiquement du système. Les fonctions qui auraient ordinairement été prises en charge par les puces originelles sont maintenant prises en charge par des puces plus performantes montées sur un module qui est enfiché dans le système. L'élimination fonctionnelle de certaines puces de l'ordinateur originel se fait par la simple insertion d'un module enfichable. Aucun remplacement ni aucune substitution des puces ou des cartes originelles n'est nécessaire. De plus, les systèmes informatiques de mise à niveau peuvent subir de nouvelles mises à niveau par le remplacement du premier module enfichable par un second module enfichable à caractéristiques de performance différentes.
