Abstract: 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.

Abstract: 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.

Abstract: A fluid coupling including an annular adapter with a cam receiving groove and an annular coupler slidable onto the adapter with cam levers movable to engage cams within the cam receiving groove. The adapter is made of Ultra High Density Polyethylene and has a metal insert or collar defining the cam receiving groove.

Abstract: A system to remotely report the load condition of a railroad car including a mechanism to sense the load condition in the form of a switch responsive to load condition to change the state of an electrical circuit, a controller to recognize the state of the circuit and a radio wave transmitter directed by the controller to report the condition to a remote receiver. Load is sensed by recognition of the distance between two components of the car, one which remains relatively fixed regardless of the weight of the car, the other which moves relative to the first component as the car weight changes.
