Abstract:
Fluid dispensing assemblies are disclosed, for use in fluid supply packages in which such fluid dispensing assemblies as coupled to fluid supply vessels, for dispensing of fluids such as semiconductor manufacturing fluids. The fluid dispensing assemblies in specific implementations are configured to prevent application of excessive force to valve elements in the fluid dispensing assemblies, and/or for avoiding inadvertent or accidental open conditions of vessels that may result in leakage of toxic or otherwise hazardous or valuable gas. Also described are alignment devices for assisting coupling of coupling elements, e.g., coupling elements of fluid supply packages of the foregoing type, so that damage to such couplings as a result of misalignment is avoided.
Abstract:
The invention relates to a protective cap for gas container, comprising a cap body forming a protective shell delimiting an internal volume designed to accommodate all or part of the valve-assembly, and an attachment device able to pivot between several angular positions, comprising a rest position in which the attachment device is fully folded, and an attachment position in which the attachment device is completely unfolded. The attachment device comprises a three-dimensional structure comprising two arms each bearing a cutout for fixing to a support, the said three-dimensional structure comprising an interior face shaped to conform to the exterior profile of the body of the cap when the attachment device is in the rest position.
Abstract:
The invention relates to a pressurised fluid container, in particular a pressurised gas cylinder, comprising a body (1) forming a sealed storage volume for the fluid. According to the invention, a first end of the body (1) comprises an opening (2), while a second end of the body (1) comprises a base (3) secured to the body (1). The body (1) is formed by a metal material, a metal alloy or aluminium. The container is characterised in that the base (3) comprises a metal material, a metal alloy or an aluminium alloy having an electronegativity on the Pauling scale that is greater than that of the material forming the body (1). The invention also relates to a method for the production of such a container.
Abstract:
A compressed gas cylinder hanger having resiliently flexible engagement with the neck of the compressed gas cylinder to fix or resist rotation of the compressed gas cylinder hanger about neck.
Abstract:
A gas cylinder (100) in the neck (20) of which is installed a balanced valve (26). The valve is fitted in the outlet of the cylinder and its output emerges into a recess (22) which opens to the top surface (23) of the cylinder. Thus the valve is protected from physical damage. A thread (27) in the bore enables the attachment of fittings such as a regulator or a filling device (not shown) which cooperate with the valve (26) to control passage of gas from or into the cylinder.
Abstract:
A pressure container comprising axially extending side walls formed of plastic extending between a top end and a bottom end. A metal top is attached at a top seam in pressure-containing relation to the top end of the side walls, and a metal bottom attached at a bottom seam in pressure-containing relation to the bottom end of the side walls. Optional top and bottom beads are formed in the side walls to aid in sealingly securing the metal top and bottom to the side walls. A method for containing pressurized materials by providing and filling such a pressure container is also shown.
Abstract:
A method of filling and sealing a gas capsule having (i) a hollow body portion and (ii) an elongate hollow neck portion having a free open distal end extending from the body portion is disclosed. The method is accomplished by applying a filling cap to the open end of the neck portion while evacuating the capsule and refilling with helium. Two crimping steps while pressure is maintained finishes the filling and sealing method.
Abstract:
The present invention relates to a spray can and a pressure releasing structure thereof, in which the pressure in the spray can can be easily and quickly released. A spray can 200 comprises a sealed can body 14 for holding a compressed fluid such as cosmetics, paints, or propane gas, a spout path 16 for leading the fluid in the sealed can body 14 to the outside, an opening/closing means 18 for opening and closing the spout path 16, and an open-state maintaining means 202 for maintaining the spout path 16 in its open state.
Abstract:
An apparatus and method for charging a gas storage and dispensing vessel with gas to a predetermined pressure level, e.g., a gas to be employed in a semiconductor manufacturing operation such as a hydride, halide or organometallic reagent gas. In the gas charging, a source gas is liquefied, e.g., in a cryotrap, and then gasified in closed flow communication with the vessel to introduce the gas thereinto, and such liquefaction/gasification steps are carried out alternatively and repetitively, to charge the vessel in a step-wise, progressive fashion with gas, until a full fill state is achieved, with the contained gas at the predetermined pressure level.
