Abstract: A work piece holder for dual-in-line packages and other electronic devices comprises a base on which is mounted a fixed jaw and a movable jaw having opposing vertical surfaces that are substantially parallel to one another. At least a portion of the area encompassed by these two jaw surfaces constitutes a grasping area for immobilizing at least one DIP or similar electronic device located on the upper surface of the fixed jaw. The movable jaw is urged into contact with the fixed jaw by at least one spring or other resilient means associated with the movable jaw. The holder is equipped with a means for releasing the secured device(s) from the holder, which comprises means for exerting a force on the movable jaw in a direction substantially opposite to the force acting on the movable jaw.

Abstract: A valve comprising a cylinder with a number of inlet and outlet ports at one end having movable therein a resiliently surfaced piston, wherein the valve is closed by movement of the piston to a position wherein the resilient surface simultaneously closes all of the ports. Means is provided to normally urge the valve toward an open position and closing means which may be highly pressurized air is provided to move the piston to a valve closed position.
