摘要:
A protective assembly for electronic components. The protective assembly has a chassis and a removable cover. The removable cover is secured to the chassis by a latch and a catch. The catch is biased by a spring to a first position. The latch slidingly engages the catch to displace the catch during the installation of the cover. The spring returning the catch to the first position when the cover is disposed on the chassis in the securing position. The panel being removeable by sliding the catch against the spring to release the latch from the catch.

摘要:
A pressure actuator is provided for a valve having a housing and an actuating stem, wherein an annular housing is attachable at one end of the valve housing and a cylindrical piston element is concentrically fixedly mounted to the other end of the annular housing. A cup-shaped cylinder is provided to cooperate in sliding and sealing relationship with the exterior of the piston. The cylinder defines an annular space between its exterior surface and the interior bore of the annular housing and spring elements are mounted in the annular space. If desired, an indicating stem passes through a bore in the fixed piston element and is interiorly engaged with the movable cylinder element, thus providing an indicating actuator wherein the total length of the actuator is not substantially in excess of twice the stroke of the actuator.
