Abstract: Disclosed are a computing device bezel and a facia button that is used with the bezel. In one embodiment, the facia button includes a base member, a finger interface that is supported by and that extends from the base member, an axis about which the facia button can pivot, and a spring member that is adapted to resist pivoting of the facia button, wherein the facia button is configured to contact and press an associated button of a device contained within the computing device.

Abstract: A self-closing actuator mechanism and a gate valve system equipped with the actuator mechanism, in which a coil spring acts on a gate valve actuating arm only in a closing direction, the coil spring being held in a compressed condition by retaining clips that are connected by a spring under tension and which carry a meltable link material on them between each clip and a holding sleeve. The clips release automatically, under the tensioning of their connecting spring, when either the holding sleeve is retracted or the link material melts. The gate valve system is designed to meet all regulations pertaining to the transportation of hazardous cargoes, while being low in cost and able to be retrofit installed on existing tank gate valves in a simple and easy manner.
