Abstract: A gas valve having a cantilevered bi-metal arm subject to electrically energized heating regulates fluid flow between a fluid inlet and fluid outlet. A poppet is preloaded for seating with a valve seat and further includes a disc member to inhibit valve teasing. Projecting fingers from the arm operatively engage the disc member to provide consistent, repetitive movement between the poppet, arm, and valve seat so that the valve is uniformly opened and closed under various operating parameters.

Abstract: An inlet control valve particularly useful in connection with pneumatic tools or the like. The valve includes a longitudinally depressible member passing loosely through a frusto-conical plug in a matching frusto-conical valve seat. In the closed position, the plug is seated and the stem is sealed by an O-ring. As the trigger is depressed, the O-ring first releases a path for fluid flow about the shaft within the plug providing an idle speed. Further depressing of the trigger causes a shoulder to contact the plug and, thereafter, move the plug rearward which provides an increasing amount of fluid flow around the plug proportional to the amount of depression thus providing a variable speed.

Abstract: A closure insert assembly (10) for a control rod drive mechanism that has incorporated therein a vent valve arrangement which permits the release of air trapped in the nuclear reactor during the filling of the primary coolant system therein and allows the entrance of air into the reactor for the draining of same. To accomplish this, the vent valve is of the ball type which engages two oppositely disposed conical ball seats (44, 70), one of which is allowed to move laterally with respect to the other, causing the ball (66) and ball seats (44, 70) to be "self-centering" and resulting in a uniform compressive force being applied over minor circumferences on the ball (66). The use of conical ball seats (44, 70), one of which is laterally movable, also permits the axes of the conical ball seats (44, 70) to be non-parallel and/or non-concentric without hindering the operation and effectiveness of the vent valve.
