    Abstract: An apparatus and method for shipping a high value liquified gas product using a low value liquified gas product as a cooling medium, the low value liquified gas product having a boiling point lower than the high value liquified gas product, the high value liquified gas product being contained in a first vessel, the low value liquified gas product being contained in a second vessel, which is contained within the first vessel, the second vessel being in heat exchange relationship with the low value liquified product contained in the first vessel whereby heat conducted to and absorbed by the high value liquified product is expended as heat of vaporization of the low value liquified product, thereby maintaining the volume of liquified high value product substantially constant and preventing expensive losses through vaporization thereof.

    Abstract: A system for transferring fluid from a filling reservoir to a receiving tank. The system includes a fluid transfer line for conveying fluid from the filling reservoir outlet to the receiving tank inlet, and couplings for selectively connecting the fluid transfer line to a filling reservoir outlet and a receiving tank inlet. The system further includes a vapor return line for conveying vapor from a receiving tank vent to a filling reservoir inlet to simultaneously prevent pressure from building in the tank and a vacuum from developing in the reservoir as fluid is transferred from the reservoir to the tank, and couplings for selectively connecting the vapor return line to the filling reservoir inlet and the receiving tank vent. In addition, the system includes a portable platform adapted for movement to a position near the filling reservoir and the receiving tank, and a pump mounted on the platform for selectively inducing fluid to travel through the fluid transfer line from the filling reservoir to the receiving tank when the reservoir outlet valve and the tank inlet valve are open. The system also includes a compressed gas source in communication with the fluid transfer line for blowing gas through the line to remove residual fluid from the line to prevent the escape of residual fluid and associated odor from the line when the fluid transfer line couplings are uncoupled from the filling reservoir outlet and the receiving tank inlet.

    Abstract: A safety shut-off system especially adapted for propane delivery trucks and the like utilizes a pressure differential switch to immediately close the outlet valve of the cargo tank in the event that the differential between an initial reference pressure in the system and the current delivery pressure becomes high enough. When the delivery process is started, both sides of the pressure differential switch are simultaneously exposed to the delivery pressure so that the switch remains in a standby condition. As the delivery pressure becomes stabilized, a timer closes a trapping valve on the high pressure side of the pressure differential switch, trapping a quantity of fluid against the high pressure side of the switch to comprise a reference pressure. The other side of the switch remains in open communication with the delivery pressure so that, if the delivery pressure should abruptly fall, the higher, pre-established reference pressure on the high pressure side of the switch causes the switch to be operated, closing the shut-off valve.

    Abstract: A system is disclosed for handling, storing, transporting and dispensing cryogenic fluids, liquid natural gas, compressed natural gas, and their equivalents. Internal valves are disclosed for dispensing such fuels from containers used in the system. The containers, in one aspect, are mounted in protective frame systems which are stackable and which provide access to the containers and the valves. A fuel injection system is disclosed for directly injecting LNG into an engine's combustion chamber. Such systems include a railroad system in which a container of fuel is carried on a flat car behind a locomotive and the, e.g. liquid natural gas, is conveyed to the locomotive with appropriate valves, conduits, pumps, and controls.
