Filter media test fixture

A flexible diaphragm can be moved to line opposite surfaces of a tank vehicle so that incompatible fluids alternately can be transported in the vehicle without the need for cleaning it. The diaphragm is prevented from entering a manway on the vehicle, and an outage gauge is confined entirely within the manway to prevent damage to the diaphragm.

Railroad tank car

A flexible diaphragm can be moved to line opposite surfaces of a vehicle so that incompatible fluids alternately can be transported in the vehicle without the need for cleaning it. The edge of the diaphragm may be held against the inside surface of the vehicle container by a series of aligned clamps that are independently movable. The terminal edge of the diaphragm is enclosed in a transient pressure absorbing chamber defined in part by the under surface of the clamps which enables the clamps to exert increased sealing pressure on the diaphragm during the transient pressure surges caused by movement of the liquid when the vehicle changes speed or direction suddenly.

Railroad tank car and method for transporting liquids

A flexible diaphragm can be moved to line opposite surfaces of a tank vehicle so that incompatible fluids alternately can be transported in the vehicle without the need for cleaning it. Both sides of the diaphragm are vented to the atmosphere automatically whenever the vehicle container is filled with fluid. The diaphragm is prevented from entering a manway on the vehicle, and an outage gauge is confined entirely within the manway to prevent damage to the diaphragm.

A flexible diaphragm can be moved to line opposite surfaces of a vehicle container so that incompatible fluids alternately can be transported in the vehicle without the need for cleaning it. The edge of the diaphragm may be held against the inside surface of the vehicle container by a clamp. The terminal edge of the diaphragm contacts an abutment around its entire periphery. The clamp extends over the diaphragm terminal edge and the abutment.

Container

A flexible diaphragm can be moved to line opposite surfaces of a vehicle container so that incompatible fluids alternately can be transported in the vehicle without the need for cleaning it. The container is loaded and unloaded in a manner which causes the diaphragm to neatly lie against the container surface without forming wrinkles, creases or bubbles. The movement of the diaphragm is controlled by the sequence and timing by which inlet and outlet conduits on opposite sides of the diaphragm are opened and closed.
