    Abstract: An isolation lock through which a workpiece item can move in a path between first and second regions at different pressures, the lock comprising a housing having an upper item entrance and a lower item exit at opposite sides of the housing, a movable member within the housing defining an item-receiving surface disposed substantially in a plane which lies at a constant acute angle to the horizontal regardless of its position to enable gravity movement of the workpiece over the surface, the member movable to translate the item-receiving surface between upper and lower positions in which, respectively, the uppermost portion of the surface is adjacent the entrance to receive the workpiece and the lowermost portion of the surface is adjacent the exit to deliver the workpiece and means providing an air-tight seal between the exit and the surface when the surface is in its upper position and between the entrance and the surface when the surface is in its lower position. The movable member is shown as a piston movable in reciprocating linear motion, the item-receiving surface comprising an end surface of the piston, and an internal flange is provided intermediate the entrance and exit, this flange disposed to engage the piston when the piston is in its upper position, a resilient seal member being disposed between the flange and the piston to provide the air-tight seal between the exit and the surface.

    Abstract: A pressure vessel including an open-ended cylindrical vessel and a plug extending into the open end of the vessel and defining a space of annular transverse cross-section therewith. One or more sealing rings are disposed in the said space and are compressed by means of a plurality of spaced studs disposed around the space and threadably engaging the vessel and the plug.

    Abstract: A lightweight sealing structure is provided for pressure vessels wherein a resilient ring carrying two O-rings is positioned adjacent the closure and wall of the vessel. Internal pressure urges the resilient ring and O-rings into sealing engagement with the internal surface of the vessel.

    Abstract: A closure system for a high pressure chamber which is particularly designed to permit the use of an interior glass coating or other non-metallic liner material. The closure design includes a demountable cover for a chamber opening, a gasket member which will extend around the interior periphery of the opening, and an inner ''''piston'''' member, which will assist in providing a sealing of the gasket member around the chamber opening. A release bolt provides for pushing inwardly against the inner piston member so as to let fluid pressure into or out of the chamber from a port located centrally in the cover member at a zone opposed by the piston member.
