Abstract: A spherical liquid dispensing system which can easily be handled by one person. This system is made from a substantially uniformly molded sphere supplied with a reinforced neck for filling and dispensing. The sphere further has a flange about its outer circumference to facilitate mounting in a stackable rectangular support frame. This spherical liquid dispensing system can be supplied with a standard solid cap or a cap with valves including a first valve to allow for the pressurization of the sphere, a second valve to dispense the contained liquid and a third valve for pressure relief. The threads and sealing surface on the neck of the sphere are designed to release contained pressure before releasing the cap and to vent the contained pressure downward from the cap.

Abstract: The present invention provides a method for coating the interior surface of a cylinder with a uniform, relatively thick layer of a polymeric material. The method includes the steps of dispersing a particulate polymeric material into the interior cavity of a cylinder. Any openings in the cylinder are then closed. The cylinder is then subjected to rotational movement while at the same time subjecting the cylinder to oscillation in a vertical plane. The polymeric material is then heated to a temperature above the melting point of the polymeric material, and maintained at that temperature for a time sufficient to coat the polymeric material onto the interior surface of the cylinder. The rotation and oscillation of the cylinder is then halted and the polymeric material is cooled.

Abstract: A liquified petroleum cylinder has a reserve cylinder within it provided with a separate outlet external to the main cylinder. The reserve cylinder may be provided with a non-return valve (not shown in FIG. 1), whereby both cylinders may be filled with gas through the same external valve.

Abstract: This invention includes an above ground gas storage vessel of tubular or cylindrical configuration. A head or cap with threads mating the threads of the tube is screwed on each end of the tube to form a pressure vessel. Each cap contains a passage therein threaded to mate a reducing bushing. The reducing bushing likewise contains a passage which is at least partially threaded. This passage may be capped to prevent gas flow or valve to allow the flow of gas as required. In an alternative embodiment, the cap assembly is inserted into the tube and retained therein. A packing assembly would be used to seal the tube to prevent the escape of gas. A plurality of vessels are secured in a vertical-parallel arrangement using a support structure to increase gas storage capacity while taking up a minimal amount of ground space.

Abstract: A boss is disposed in a polar opening in a pressure vessel which has a filament wound outer shell and a non-metallic internal liner. The boss has a tubular neck which projects outwardly from the vessel interior and an annular support flange which extends radially from the internal end of the neck and supports the perimeter of the polar opening. An offset attachment flange extends radially from the support flange and has two axially opposed surfaces with locking grooves formed therein. Each locking groove has a bottom wall intermediate a pair of mutually skewed sidewalls for maintaining positive engagement with and retention of complementary respective tabs on the liner. In an application where the liner is a blow molded component, an injection molded interface member is attached to the support flange and provides a site at which the liner is welded.

Abstract: A radiation-shielding storage/transport container has a cast-iron vessel having an open end defining an end face, a steel ring engaging the end face and forming at least one annular seat, a weld unitarily bonding the ring to the end face, and a cover secured to the steel ring in the seat thereof. The cast-iron vessel is formed at its open end with an annular seat having a shoulder surface forming the end face. The weld is an aluminothermic weld that extends over the entire surface of the interface between the ring and the vessel. The ring is formed with two such seats and the cover includes an inner plug cover and an outer cover each in a respective one of the seats. The outer cover is of steel and a second peripheral weld connects the outer cover to the respective seat.

Abstract: The invention teaches apparatus suited for holding highly corrosive solvents heated under sealed conditions to temperatures up to 500.degree. C., for even extended durations. The apparatus is in the form of an open top vessel having a removable cover therefor, a seal cooperating between the vessel and cover, and clamping structures isolated radially beyond the seal from the vessel contents to hold the cover and vessel sealed together. The vessel and cover can be made structurally of chemically resistent material, such as a nickel alloy; or can be made as a separate chemically resistent liner, cover and seal structure contained within an outer pressure shell and cover, and clamping structures. The liner, cover, and seal would be formed of chemically resistent tantalum (Ta), platinum (Pt) or polytetrafluoroethylene. Gem-quality diamonds can be refined by using different related vessels exclusively to hold respective caustic, acid and rinse solvents, and moving the diamonds from vessel to vessel sequentially.

Abstract: A shutter for large pressure vessels comprises a lid assembly (Y) constituted of a seal plate (1) formed of a flexible material of a size fit for the opening of a pressure vessel and a multitude of beam members (2) attached to the outer surface of the plate (1) and extending widthwise. The beam members are connected to the seal plate in such a manner as to be parallel to each other along a reference line for connection, extending in the widthwise direction of the seal plate, and advance or retreat while flexing along a guide member (7) having at least one bending portion (71). The guide member extends between a closing position (A) disposed in front of the opening portion and a storage position (B) disposed on an outer housing of the pressure vessel, so that the assembly can be housed in a relatively small space. This shutter is most suitable for use on a medical autoclave and a retort for food processing.

Abstract: A ring assembly for compressed gas cylinders includes either a separate adaptor removably attachable to existing gas cylinders or, a ring member integral with the top portion of manufactured cylinders. In any case, a ring plate provides a horizontal, radially disposed lift plate that serves to allow lifting, transporting and storage of the cylinders. In the adaptor version, the ring plate surrounds a collar having upper and lower portions respectively provided with external and internal threads. The lower portion threads engage with the existing external threads on the top portion of gas cylinders and which normally provide for attachment of the required safety cap while the upper portion threads duplicate the cylinder threads and thus enable attachment of the protector cap thereto. Manipulation or hanging of a cylinder equipped with the ring adaptor may be by manual grasping of the ring plate or by insertion of lift hooks into holes formed in the ring plate or by placing lift forks beneath the plate.

Abstract: This invention relates to vessel for high pressure and optionally high temperature processes. More specifically it relates to a pressure vessel having a non-threaded plug, the vessel being useful as a chemical reactor and for polymer processing at high pressures and optionally elevated temperatures.

Abstract: A remotely operable vessel cover assembly used with a vessel. The cover assembly has a mounting rim secured to the vessel surrounding a circular opening and a circular cover to fit against the mounting rim. A force ring having a plurality of openings is attached to the cover. Connector pins are attached to and extend from the mounting rim and through a plurality of holes in the cover and the force ring. A lock ring is rotatably attached to the force ring and locks the extending heads of the connector pins to the force ring to restrain the cover in an initial position. A force actuator, disposed between the force ring and the cover, expands under fluid pressure to react against the cover forcing the cover against the mounting rim. Upper and lower ramps are connected to the periphery of the cover and a ramp ring respectively. The ramp ring, rotatably supported between the force ring and the cover, has lower ramps positioned to match upper ramps on the cover.

Abstract: A safety seal for a pressurized system, such as a pressurized oil sprayer used in lubricating engines, or a pressurized paint sprayer, wherein the closure, for an inlet member, for addition of material such as oil or paint, is prevented from being removed, when the system is in the pressurized state. A resilient band, inaccessible from the exterior of the system, is tightly compressed by internal pressurization against an interface between the closure and inlet member thereby locking the closure into a non-removable position. Reduction of internal pressure permits the resilient band to contract away from the interface, thereby unlocking the closure from its non-removable position, with the closure being removable thereafter for addition of material into the inlet.
