Abstract:
Disclosed are a device for protecting a container and a container equipped therewith. The container is, in particular, a container made of composite material intended to contain a fluid under pressure, and having a cylindrical side wall and rounded ends forming a dome. The device includes a shell made of a puncture-resistant material, shaped to envelope at least the entirety of the dome of the container, delimiting a space between an interior face of the shell and an exterior face of the wall of the container, and a compressible element capable of deadening a knock or impact, disposed in the space.
Abstract:
A deep ocean gas storage system for storing compressed gas, the system comprising an inflexible thin walled storage vessel anchored to the sea floor having an axis located in water substantially perpendicular to and on a sea floor below sea level, a gas intake for admitting and discharging compressed natural gas to and from the vessel; a water port for admitting and discharging water to the vessel using hydrostatic pressure to discharge compressed gas from the vessel at a substantially constant discharge pressure as the volume of the gas in the storage vessel decreases when water content of the vessel increases; a conduit fluidly connected with the water port oriented substantially parallel to the axis having a discharge opening above the level of sea water in the vessel; and a valve disposed at the gas intake to the vessel for controlling compressed gas admission and discharge.
Abstract:
A fuel cylinder for use in fueling vapor-powered machines and devices is claimed. The fuel cylinder contains a fuel vapor withdrawal pipe that bends upward towards the top edge of the cylinder when the cylinder is in its position of use, for example, the horizontal position if the tank is used horizontally. A liquid splash guard surrounds the inlet of the fuel vapor withdrawal pipe to protect the inlet from splashing of liquid propane in the cylinder. A brace connects to the fuel vapor withdrawal pipe to stabilize the fuel pipe during high vibration use. In one embodiment, the splash guard and brace are welded to the internal surface of a joggle in the rim of the upper head portion of the cylinder before the upper head portion and lower head portion of the cylinder are mated and welded together.
Abstract:
A portable propane tank carrier system is provided which includes a tank carrier, stabilizer ring, and tank neck cover. The tank carrier includes a rectangular main tank cover panel, and upper and lower radial sidewall panel. The tank carrier closely conforms to the shape of a portable propane tank while providing an upper opening adapted to receive a neck portion of the tank and a lower opening adapted to receive a tank base ring portion of the tank. The stabilizer rings may be attached to the bottom of the tank carrier to prevent the tank from tipping over.
Abstract:
A method of generating a high-level vacuum comprises evacuating a chamber having a substantially-pure gas therein to a medium-level vacuum, and freezing the residual gas to generate the high-level vacuum within the chamber. Impurities, such as atmospheric air, may be purged from the chamber by evacuating the chamber to a medium level vacuum (e.g., around 10−2 Torr) and subsequently filling the chamber with the gas. This purging process may be repeated multiple times to decrease the level of impurities in the gas filling the chamber. The substantially-pure gas may have an impurity-level of less than approximately 100 PPM and may comprise carbon-dioxide, although the scope of the invention is not limited in this respect. The medium level vacuum may range between approximately 1×10−2 Torr and 5×10−2 Torr allowing the use of a roughing pump, and the high-level vacuum may range between approximately 1×10−5 and 1×10−8 Torr.
Abstract:
A mounting bracket having a living hinge operable to enable mounting straps of the mounting bracket to move between retracted and extended positions. In the extended position, the mounting straps are configured to extend around and retain a fire extinguisher. In the retracted position, the mounting straps are removed from the fire extinguisher. The living hinge may include a continuous piece of material that extends between the mounting straps and a base member of the mounting bracket to which the mounting straps are coupled.
Abstract:
A system and method of transferring, by a patient, high purity gas from a supply source to a portable cylinder. The system comprises a regulator that operatively connects to the supply source that stores the high purity gas. A cylinder valve removeably connects with the outlet of the regulator while a residual pressure valve operatively connects to the cylinder valve. The residual pressure valve includes a chamber in communication with the cylinder valve, wherein a piston assembly separates the chamber into a high pressure area and a low pressure area. During a fill process, the portable cylinder removeably connects to the valve outlet such that the high purity gas flows directly into the chamber via the regulator and cylinder valve to slide the piston assembly within the chamber to allow the flow of the high purity gas through the chamber and into the portable cylinder. During a non-fill process, pressure of residual gas of the high purity gas slides the piston assembly in contact with the cylinder valve to seal the chamber from atmospheric contaminants while maintaining a residual pressure of the residual high purity gas within the portable cylinder.
Abstract:
This invention relates generally to an improvement in low pressure storage and dispensing systems for the selective storing of gases having Lewis acidity or basicity, and the subsequent dispensing of said gases at pressures, e.g., generally below 5 psig and typically below atmospheric pressure, by modest heating, pressure reduction or both. The improvement resides in storing the gases in a reversibly reacted state within a reactive liquid having opposing Lewis basicity or acidity.
