Abstract:
A high-efficiency liquid oxygen, (LOX) storage/delivery system utilizes a portable LOX/delivery apparatus with a portable LOX container. A portable-unit LOX transfer connector is connected to the portable LOX container and is connectable to a main source of LOX in a primary reservoir LOX container. A portable-unit oxygen gas transfer connector is provided for transferring oxygen gas from the portable LOX container to an oxygen gas delivery device for delivering oxygen gas to a patient. An inter-unit oxygen gas transfer connector also is provided for connecting the portable apparatus to a stationary source of oxygen gas in the primary reservoir container, for transferring oxygen gas to the portable apparatus. A portable-unit primary relief valve is connected to the portable LOX container for venting oxygen gas out of the portable LOX container when pressure in the portable LOX container reaches a predetermined level. When the inter-unit oxygen gas transfer connector of the portable container is connected to the stationary source of oxygen in the primary reservoir container, oxygen gas can be transferred to the oxygen gas delivery device for delivery to the patient from the portable LOX container while oxygen gas is transferred to the portable container from the stationary source of gas in the primary reservoir LOX container.
Abstract:
This invention is directed to an apparatus for controlling the discharge of pressurized fluids from the outlet of a pressurized vessel, and particularly directed to multiple fluid dispensing check valve devices within the vessel for storing and controlling the flow of fluid or gases out of the vessel.
Abstract:
An apparatus for safely delivering a hazardous fluid substance to a receiving structure includes first and second supply cylinders containing the fluid substance and each supply cylinder having a supply cylinder release port; a high pressure containment vessel having a vessel wall and being sized to receive and safely enclose the first and second supply cylinders; a high pressure first tube extending from each of the first and second supply cylinders, and in fluid communication with the supply cylinder release ports and extending to and being in fluid communication with a vessel port in the vessel wall; and a vessel valve in fluid communication with each of the first tube for controlling delivery of the fluid substance from the first and second supply cylinders and from the vessel.
Abstract:
A liquefiable gas pressure cylinder and method for making the same with the cylinder including a cylindrical shell, and heads fusion welded at opposites ends of the shell. The side ends where the heads are joined to the shell are crimped radially inward to each end to form chimes. The welds are 100% radiographed and heat treated. The heads are dished to have a domed center portion which has a profile and thickness so that the domed center portions will reverse before any other part of the cylinder is stressed beyond a yield limit for such part.
Abstract:
A fluid storage and dispensing system including a fluid storage and dispensing vessel enclosing an interior volume for holding a fluid. The vessel includes a fluid discharge port for discharging fluid from the vessel. A pressure regulating element in the interior volume of the fluid storage and dispensing vessel is arranged to flow fluid therethrough to the fluid discharge port at a set pressure for dispensing thereof. A controller external of the fluid storage and dispensing vessel is arranged to transmit a control input into the vessel to cause the pressure regulating element to change the set pressure of the fluid flowed from the pressure regulating element to the fluid discharge port. By such arrangement, the respective storage and dispensing operations can have differing regulator set point pressures, as for example a subatmospheric pressure set point for storage and a superatmospheric pressure set point for dispensing.

Abstract:
A gas storage and dispensing system comprising a vessel for holding a gas at a desired pressure. The vessel has a gas pressure regulator in its interior volume, to maintain pressure of dispensed gas at a desired pressure determined by the set point of the regulator. A second gas pressure regulator may be joined in series gas flow communication with the first gas pressure regulator, with the second gas pressure regulator being in initial contact with gas that is dispensed prior to its flow through the first gas pressure regulator, and with the set point pressure of the second gas pressure regulator being at least twice the set point pressure of the first gas pressure regulator.
Abstract:
The present invention provides a heating apparatus for effectively heating a gas container, and more particularly a liquified gas filled in the gas container. The heating apparatus comprises a mounting base having a first space and a second space, each formed in its inside, and an air fan heater for supplying heated air to the first space of said mounting base. In said mounting base, a first through hole communicating with said first space and second through holes communicating with said second space are formed inside of a mounting area, and third through holes communicating with said second space are formed outside of said mounting area. When a gas container is mounted on the mounting base, the heated air is blasted from said first space onto the bottom face of said gas container through said first through hole, whereby heat is effectively transmitted from the bottom face of the gas container to the liquified gas contents of the gas container.
Abstract:
A convoluted or multiple-pass neck tube joins inner and outer elements of a vacuum-jacketed vessel. The additional length of the convoluted neck tube creates an increased distance for heat to conduct from the outer to the inner vessel. As such, a convoluted neck tube can be substitute in place of a straight neck tube or a bellows neck tube to reduce heat gain into the inner vessel. An additional benefit achieved by the convoluted neck tube is greater flexibility of the neck tube, thus yielding more stress resistance.
Abstract:
A dual-chamber composite pressure vessel includes a first enclosure formed of a fiber reinforced resin matrix, having a hollow cylindrical central section, and first and second oblate end sections formed integrally over respective ends of the central section to define a first chamber. Also included is a second enclosure formed of a fiber-reinforced resin matrix, integrally with the first enclosure, and having a second hollow cylindrical section which is joined at one end to and extends from the second end section co-cylindrically with the central section of the first enclosure. The second enclosure also includes a third oblate end section formed integrally over the other end of the second cylindrical section to define a second chamber.
