摘要： A gasket for sealing between the open end of a manway nozzle body of a containment vessel and an associated cover comprising a resilient annular ring member having a bail including a plurality of rigid arcuate inserts spaced about the bail that extends between radially inner and radially outer depending legs. The bail includes at least one annular upstanding chevron extending about an upper surface and at least one annular depending chevron extending about a lower surface. The inserts and bail have about the same thickness. A method includes compressing the gasket between the manway nozzle and cover, and the rigid inserts limit the compression of the gasket.

摘要： A handle assembly is provided for an outlet valve of a tank car wherein the outlet valve has a valve stem rotatable about an axis and is operative to open and close the outlet valve. The handle assembly includes a valve handle for manually opening the outlet valve, a rotatable shaft coupled to the handle, and a coupling coupled to the outlet valve and selectively coupleable to the shaft. A valve rotation control structure includes a first movement control component on one of the coupling and the shaft. The valve rotation control structure is configured to permit the coupling or shaft to move parallel to the axis of the valve stem between a first locked position and a second rotatable position and to rotate about the axis of the valve stem between a first valve closed position and a second valve open position at the second rotatable position.
