Abstract:
A sealed and insulating reservoir to contain a pressurized cold fluid, the reservoir comprising: a sealed rigid enclosure (4), a sealed membrane (1) intended to be in contact with the cold fluid contained in the reservoir, an insulating barrier (3) positioned between the sealed membrane and the internal surface of the rigid enclosure, the insulating barrier forming a supporting surface to support the sealed membrane, and a pressure‑equalizing device (5) able to limit the pressure differential between a first sealed volume (2) situated on the inside of the sealed membrane and a second sealed volume (3) situated on the outside of the sealed membrane.
Abstract:
A method and apparatus for compressing gases and supplying compressed gaseous fuel to a consuming device, such as a gaseous fueled vehicle or the like. One embodiment includes a gas compressor for compressing the gaseous fuel to an array of tanks having predetermined initial set points which are increasing for tanks in the array. One embodiment provides a selecting valve having first and second families of ports wherein the valve can be operated to select a plurality of ports from the first family to be fluidly connected with a plurality of ports with the second family, and such fluid connections can be changed by operation of the valve.

Abstract:
The present invention relates to a system (1) and method of refilling gas cylinders (3), that can be installed at retail sales establishments or on a vehicle to allow the consumer or user to directly refill an empty cylinder (3) at or near residential areas convenient to the consumer. The system (1) includes a quick coupler (9) that automatically connects with a fill valve (7) of a cylinder and a supply line (15) that extends between a reservoir (2) and the quick coupler (9) for transferring fluid to the cylinder. During a filling operation, the cylinder (3) is located within a locked compartment (4) to prevent user access. A control panel (5) allows the consumer to select a predetermined quantity of fluid to be delivered.
Abstract:
A portable liquid oxygen system may provide an average flow rate of oxygen gas at approximately 6 - approximately 20 Ipm using a rapid gas conversion mode. The liquid oxygen system may weigh less than 10 pounds. A heat exchanger may be provided, and wherein the rapid gas conversion mode may utilize a heater on the heat exchanger. The rapid gas conversion mode may utilize a Stirling engine passing air from a hot sink across the heat exchanger to a cold sink. The system may have multiple modes of operation. The modes of operation may be a continuum of settings and not discrete modes of operation. Flow capacity may be changed when switching between modes of operation. Oxygen gas pressure may be changed when switching between modes of operation. The system may automatically switch modes of operation based on a patient's condition.
