Abstract: The invention disclosed relates to an apparatus for purging hazardous or volatile materials from external loading lines fixed to the bottom of cargo tank compartments. According to the invention, pressurized gas is directed into each external loading line to force the material to the lowest point in the loading line, through a purging tube, and back into the cargo tank compartment.

In another embodiment, the apparatus is partly contained on the cargo loading facility and partly contained on the cargo tank.

Abstract: A method and apparatus for filling of a dispensing container with a product to be dispensed, particularly useful for highly viscous products, in which the container has a vented dip tube structure which is inserted into the container before it is filled. Filling is accomplished by inserting a filling nozzle into the container so that it cooperates with the top of the dip tube. Filling of the container therefore occurs through the dip tube. The vent in the dip tube structure allows the air in the container to be vented as the container is filled. Because the container is filled through the dip tube, the product completely fills the dip tube at the time when the pump structure is inserted into the container. The vent structure can be used as a vent for the container during a dispensing operation as well.

Abstract: A method and apparatus for filling of a dispensing container with a product to be dispensed, particularly useful for highly viscous products, in which the container has a vented dip tube structure which is inserted into the container before it is filled. Filling is accomplished by inserting a filling nozzle into the container so that it cooperates with the top of the dip tube. Filling of the container therefore occurs through the dip tube. The vent in the dip tube structure allows the air in the container to be vented as the container is filled.

Abstract: In a valve assembly receivable in an outwardly projecting neck in a keg, for normally sealing the keg and for cooperation with a detachable coupler by which the keg is tapped, the cylindrical spring retainer of the assembly has at its axially inner end deflector surfaces so liquid flowing inward along that cylindrical wall during filling of the keg through the gas passage of the valve assembly is deflected radially across the inner end edge of that wall as a sheet-like jet. This prevents upward spray out of the annular space between the siphon tube and the spring retainer, thus preventing overcarbonation, excessive foaming and underfilling of the keg.
