Abstract:
The present invention provides a system (1) to prevent the formation of fuel vapors comprising a containment tank (10) and a variable volume tank (12) accommodatable within the containment tank (10), wherein the variable volume tank (12) is configured to receive liquid fuel. Our invention can be used in any tanks or reservoirs of liquid products that attack the ozone layer, preventing the formation of vapors that are extremely harmful to nature and the environment.
Abstract:
A unit for inflating an inflatable object includes a first sub-system for initially inflating the inflatable object and a second sub-system for automatically adding air to the inflatable object when the air pressure within the object falls below a predetermined threshold after inflation. The air pressure within the inflatable object is monitored and measured by an electric pressure sensor that communicates with a PC circuit board. The unit allows air into and out of the inflatable object using a solenoid configured to open and close a valve. The first and second sub-systems are both contained within the same housing affixed to the inflatable object and use the same solenoid and valve to add air into the inflatable object.
Abstract:
An orientation independent delivery device. The delivery device includes a gas chamber, a delivery chamber, a gas cell, and a delivery aperture. The gas chamber includes a gas-side rigid portion and a gas-side flexible barrier. The gas-side flexible barrier is sealed to the gas-side rigid portion. The delivery chamber includes a delivery-side rigid portion and a delivery-side flexible barrier. The delivery-side flexible barrier is sealed to the delivery-side rigid portion and is oriented adjacent to the gas-side flexible barrier. The gas cell is coupled to the gas-side rigid portion of the gas chamber. The gas cell increases a gas pressure within the gas chamber to expand the gas-side flexible barrier. Expansion of the gas-side flexible barrier applies a compressive force to the delivery-side flexible barrier allowing a delivery material to escape from the delivery chamber.
Abstract:
A gas container and method of maintaining gas in a container and assembling a gas container are provided. The gas container includes at least a first section and a second section with the first and second sections being substantially hollow and movable relative to each other and a liquid seal for sealing gas within the container. The liquid seal is disposed between the first section and the second section, wherein a first anti-corrosion coating is provided so as to float on the surface of the liquid in the liquid seals, such that in use, the first anti-corrosion coating is caused to be applied to at least a portion of the second section during motion of the second section relative to the first section.
Abstract:
A system and method utilizing compressed gas according to which the gas is compressed at a location above ground and transported to an underwater location. The gas is stored at the underwater location and later returned from the underwater location to the above-ground location for utilization as energy.
Abstract:
A transport unit includes a plurality of permanent magnets arranged to provide a magnetic holding field for protecting hyperpolarized gas during storage and/or transport. The permanent magnets are configured in a relatively light weight manner to project a substantially cylindrical magnetic holding field or spherical holding field in space. The magnet arrangements can include primary magnets and field shaping secondary magnets which act to enlarge the region of homogeneity. The permanent magnet arrangement can also be provided with a cylindrical shaped flex sheet magnetically activated to provide the magnetic holding field. The permanent magnet arrangements do not require disassembly to insert or remove one or more containers of hyperpolarized gas in or out of the transport unit.
Abstract:
A compact portable transport unit for shipping hyperpolarized noble gases and shielding same from electromagnetic interference and/or external magnetic fields includes a means for shifting the resonance frequency of the hyperpolarized gas outside the bandwidth of typical frequencies associated with prevalent time-dependent fields produced by electrical sources. Preferably the transport unit includes a magnetic holding field which is generated from a solenoid in the transport unit. The solenoid includes a plurality of coil segments and is sized and configured to receive the gas chamber of a container. The gas container is configured with a valve, a spherical body, and an extending capillary stem between the valve and the body. The gas container or hyperpolarized product container can also be formed as a resilient bag. The distribution method includes positioning a multi-bolus container within the transport unit to shield it and transporting same to a second site remote from the first site and subsequently dispensing into smaller patient sized formulations which can be transported (shielded) in another transport unit to yet another site.
Abstract:
An improved cryogenic tank is provided which has insulation secured to the inner surface of the tank and a relatively thin sealing membrane within the tank to contain cryogenic liquid. Space containing the insulation is maintained at a reduced pressure sufficient to maintain the insulation in engagement with the outer tank wall.
Abstract:
The present invention provides a compressed fuel tank, comprising: an inner tank in which liquefied gas is stored; a support rod penetrating a central axis of the inner tank and having both sides of the inner tank fixed at both ends thereof; an insulating member provided to surround the inner tank so as to block heat transfer to the outside; an outer tank accommodating the inner tank, the support rod and the insulating member therein; and a rod support part fixed to both sides of the inside of the outer tank to support both ends of the support rod so as to transfer the load of the inner tank to both sides of the outer tank.
