Title: Cavitation free throttle valve - with two or more stages of progressively increasing flow area to avoid noise
IPC: F16K47/08
Filed: 1975-01-13
Abstract: The valve may have a housing with an inlet and an outlet.

Patent FR-2269130-A1 (FR)
IPC: G09G3/04
Filed: 1975-02-28
Abstract: A horological instrument includes a liquid crystal electro-optical display which simulates the movement of hands about a center by activating circumferentially spaced radial conductive segments. Generally, for the liquid crystal material between two corresponding segments to be activated an electrical potential must be applied between the segments which is, typically to achieve full brightness, substantially greater than the activation voltage of the liquid crystal material. The present invention effects activation of a selected segment-hand by applying an electrical potential, predetermined greater than the activation voltage, between the selected segment-hand and a corresponding segment or electrode. However, the deleterious effects of leakage currents and/or unwanted activation of a segment-hand not selected for activation is reduced by applying an electrical potential between all unselected segment-hands and their corresponding segment or electrode, which electrical potential is predetermined to be less than the activation voltage of the liquid crystal material.
