摘要:
A fluid container (10) for fluid containment. The internal surface of the container body (12) defines a fluid-containment chamber (14), which has at least one fluid inlet and/or outlet port (18). Associated with at least one fluid inlet and/or outlet port (18), there is a fluid-flow control device, having a control body (16)integrally formed with the container body (12) as one piece.

A device and method for extracting tubular structures are provided. An incision is made at a proximate and at a distal end of a tubular structure. An extracting device is inserted into and passed through a tubular structure until the operational head of the device extends past the distal incision. An actuator on the handle of the device is actuated, longitudinally extending the operational head of the device. The edge of a tubular structure is positioned axially in the mouth of a hook wire on the operational head. The actuator on the handle is released and the hook wire engages and captures the tubular structure. The user manually pulls the tubular structure, invaginating and removing it.

A steel liner (a pipe or vessel) is wrapped with a stack of sheets of glass fiber-reinforced epoxy matrix composite arranged in angle ply pattern. The stack is cured on the liner to bond the sheets together and to the liner. The wrapped liner is then internally pressurized to cause the liner to yield while the composite remains elastic. When de-pressurized, the liner has compressive residual stress and the composite has tensile residual stress. When the resulting hybrid structure is subsequently again pressurized, it is found that the elastic regime of the liner has been extended.

A highly reliable digital level sensor assembly (321) is provided to replace optical (34) and capacitance type sensors in high purity chemical delivery systems (218). The digital level sensor assembly (321) is particularly useful in bulk chemical refill delivery systems (218) for high purity chemicals employing a manifold (222) that ensures contamination free operation and canister change outs with a minimum of valves and tubing.
摘要:
A method of coating an interior of a gas storage container, where the method includes supplying a chemical vapor precursor to the storage container, and forming a metal coating on the interior surface of the container, where the coating is formed from the chemical vapor precursor. Also, a gas storage container that includes a gas storage vessel with an interior surface that has a liner formed on the interior surface of the storage vessel. The liner may include tungsten metal with a purity of about 99%, by weight, or more. Additionally, a system for making a metal lined gas storage container that may include a chemical vapor precursor generator, and a precursor injection assembly for transporting the precursor into a gas storage vessel. The system may also include an exhaust outlet for removing gaseous deposition products from the gas storage vessel.
摘要:
A cylinder having an integral valve body and a method of making the same which includes the steps of selecting a body of material; forming a valve body in the body of material; and removing material from the body of material to form at least a portion of the cylinder wall which is integrally formed with the valve body. The integration of the cylinder with the valve body eliminates the seal commonly found between conventional cylinders and valve bodies and, accordingly, significantly reduces back diffusion into the cylinder having an integral valve body. Additionally, the above cylinder and integral valve body can be combined with a valve stem which forms a metal to metal seal with the valve body and thus, eliminates the need for any seal elements, for example polymeric or elastomeric seals. This further minimizes any potential back diffusion into the cylinder. The remainder of the cylinder is preferably formed by one of various types of enclosures. One embodiment preferably uses a generally straight valve body design. The significantly reduced diffusion experienced by these cylinders having integral valve bodies makes them ideal for use as miniature transportable cylinders without compromising the ability of the cylinders to stably contain reactive gases.

An apparatus for winding steel ribbon (70) around a vessel inner shell (22) to construct a pressure vessel includes a vessel support and rotation mechanism (30), a vessel elevation adjusting mechanism, tracks (46) for supporting and guiding the vessel support and rotation mechanism, a carriage (54) having rail track engaging mechanism for traveling adjacent the vessel inner shell, and a ribbon pulling mechanism (76) mounted on the carriage for delivering the ribbon under tension to pre-stress the vessel. The apparatus preferably includes a locking mechanism for locking the vessel support and rotation mechanism to the track, after positioning it at the ends of the vessel inner shell. The vessel support and rotation mechanism includes several vessel support rollers (30) mounted on tracks. A method for winding steel ribbon using the apparatus mounting a vessel inner shell, securing an end of the ribbon to the inner shell, delivering the ribbon to the inner shell under tension, and advancing the carriage along the track.
