Abstract:
A compression tank device (1) for sea transport of petroleum products, comprising a relatively elongated metallic cylindrical portion (4) and end gables (6, 6null), the cylindrical portion (4) being fixedly connected to the end gables (6, 6null) through sealing connections (16, 16null), and the cylindrical portion (4) of the compression tank (1) and a portion of the end gables (6, 6null) being braided with a fibrous material (8), the fibrous material (8) being oriented mainly in the circumferential direction of the compression tank (1).
Abstract:
This container (1) is, in particular, a container made of composite material intended to contain a fluid under pressure, and having a cylindrical side wall (1a) and rounded ends (1b), commonly known as nulldomesnull. The device (2) comprises: a shell (10) made of a puncture-resistant material, shaped to envelope at least the entirety of a dome (1b) of the container (1), delimiting a space between its interior face and the exterior face of the wall of the container (1); and a compressible material (11) capable of deadening a knock or impact, filling the entirety of the aforementioned space.
Abstract:
The present invention provides a compressed gas cylinder that is capable of storing a compressed fluid at high pressures. The cylinder of the present invention includes a body terminating in an inwardly domed cap. The dome included in the cap of the compressed gas cylinder of the present invention is formed such that the material near the tip of the dome is relatively thinner than the material near the base of the dome. The tip of the dome, therefore, creates a pierce region in the cap that can be pierced through the application of a relatively low pressure.
Abstract:
A surge prevention valve may be used to prevent the formation of an initial surge of high pressure. The valve may be located, for example, between a high pressure gas cylinder and a medical pressure regulator. The valve is provided with first and second valves located within a housing and integrating a pressurization orifice. The initial opening of the valve in an axial direction enables gas to flow through the pressurization orifice at a first flow rate. The full opening of the valve in the axial direction enables the gas to flow through the second valve at a second flow rate, which is much higher than the first flow rate. The controlled pressurization of the gas through the orifice delays the time during which the gas reaches full recompression. The valve may be further provided with a vent for venting pressurized gas away from a nominally closed top surface of the lower valve element. The valve may be also provided with a valve inlet tube extending into a gas cylinder to prevent contaminants, particles and/or impurities from entering the valve.
Abstract:
A removable debris shield and method to internally protect a portion of a vessel, such as a pressure vessel, during fabrication. Pliant material sufficient to span a desired interior portion of the vessel has a hem located around the periphery of the material and having at least one opening. A hoop is removably inserted through the opening into the hem to extend the material across the desired interior portion of the vessel. In one embodiment, a spreader bolt spreads the hoop to force it tightly against the walls of the vessel.
Abstract:
Compressed gas canister (1null) intended to supply gas to a fastening appliance (2) that runs on compressed gas, comprising a protective edge (12) forming a bowl inside which an ejection valve (16) having a bearing and displacement surface (26) is mounted so that it can move in translation between a position of rest and a gas-ejection position, the ejection valve (16) being mounted, inside a seal (3null), set back from the edge (15) of the bowl, and the bearing surface (26) of the valve (16) does not protrude beyond the edge (15) of the bowl in the position of rest and is set back from the surface (30) facing towards the outside of the seal (3null, 23) in the gas-ejection position.
Abstract:
A method of, and apparatus for, closing an opening defined at least in part by a wall which at least partially surrounds the opening. The wall has a first thickness. According to one embodiment, a strip of material includes a groove which opens in a first direction and resilient projections which extend in a second, generally opposite direction from the first direction. The method according to this embodiment includes receiving the edge of the surrounding wall in the groove. The projections project at least partway across the opening substantially to obstruct access to it. In another embodiment, a method of closing an opening defined at least in part by a wall of a cover for a valve of a fuel tank includes providing a device having a perimetrally outwardly opening groove. The device further includes resilient projections which extend generally in an opposite direction to the direction in which an adjacent region of the groove opens. The groove receives the edge of the surrounding wall. The projections project at least partway across the opening substantially to obstruct access to it.
Abstract:
A bracket for restraining a compressed gas cylinder in an upright position against a wall, said bracket being adjustably secured to a horizontal strut. The strut is a channel with inward curved lips along its tip and slots on the bottom of the channel to allow the strut to be attached to a wall. The strut nuts and strut bolts adjustably connect the bracket to the strut. The bracket secures the compressed gas cylinder to the bracket. More than one bracket can be attached to the strut.
Abstract:
A camping-type container for a liquified gas fuel. The inventive container comprises: a container body formed of a transparent material such that a user can see the liquid level of the liquified gas fuel in the container; a top end structure provided on the top end of the container body; and a discharge valve provided in the top end structure, the discharge valve being a valve of the type attachable to a camping-type appliance.
Abstract:
A gas supply system including a gas cabinet defining an enclosure including therein a gas dispensing manifold and one or more adsorbent-based gas storage and dispensing vessels mounted in the enclosure and joined in gas flow communication with the gas dispensing manifold. The enclosure may be maintained under low or negative pressure conditions for enhanced safety in the event of leakage of gas from the gas storage and dispensing vessel(s) in the enclosure. The gas supply system may be coupled to a gas-consuming unit in a semiconductor manufacturing facility, e.g., an ion implanter, an etch chamber, or a chemical vapor deposition reactor.
