  • Patent number: 6223925
    Abstract: A mechanism for selectively securing a cover to a flange of a pressure vessel. A plurality of such devices can be employed, using a plurality of studs that extend through matching openings in the flange and cover. A movable anchor plate or plates, also with holes through which each stud extends, is disposed adjacent to the flange or cover. The head of each stud will fit through its associated hole of the anchor plate (and into the opening of the closer one of the flange or cover) only if the anchor plate is properly oriented. When the anchor plate is so oriented, a piston head at the opposite end of the stud can be actuated away from the flange and cover to retract the stud head into the opening of the flange or cover. This protects the stud when the cover is disengaged from the flange. The stud can be biased in the opposite direction to permit the anchor plate to be reoriented into a position in which the stud head cannot pass through the anchor plate, so the stud can clamp the flange and cover together.

The backing plate assembly located within the interior of the tank provides a solid structure that can be used to anchor the access plate onto the tank wall over the opening. Interior and exterior gaskets are used to create a fluidtight seal around the opening and to facilitate assembly of the mounting assembly.

  • Patent number: 5425466
    Abstract: A combination manway cover and pressure relief apparatus (2) for a tank (4) having a manway opening (14) and containing a fluid. A body (12) covers the manway opening and is guided and biased along a substantially vertical, linear path (16). The body is guided along the path by bolts (18) which pass through a plurality body, gasket and flange bolt holes (22, 23, 24). The weight of the body biases the body along the path toward the manway opening. Pressure relief for the tank is provided when the fluid pressure within the tank moves the body away from the manway opening.

  • Patent number: 5346090
    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.

  • Patent number: 5316167
    Abstract: A container for a fuel tank having an access opening is provided with a closure which fits within a channel in the container to cover the access opening. An elongated bolt has a collapsible cylinder located between the bolt head and the top of the closure to hold the closure to the container. The cylinder is located about the shank of the bolt, and is collapsible above a selected threshold pressure. Under normal bolting conditions, the cylinder is rigid to provide sufficient force to maintain the closure against the tank. Should an abnormal pressure develop within the tank, the closure moves axially along the shank of the elongated bolt, crushing the cylinder and providing additional tank volume to absorb the increased fluid pressure. This reduces the likelihood of catastrophic failure of the closure and also reduces pressure stress on the other tank structures.

  • Patent number: 5297693
    Abstract: A closure member for sealing an opening for a cavity in a housing to prevent fluid from being communicated to the surrounding environment. The closure member has a shaft with an end member having a irregular radial surface thereon. A first torque is applied to the irregular surface to move threads into corresponding threads in the housing to join the closure member to the housing. A self locking fastener has as stem with threads that extend from a head that engages the housing when a second torque is applied to the head. A washer retained on the stem engages the irregular surface and deforms as the second torque is applied to the head. The deformation prevents relative rotation to thereafter occur between the closure member and housing to assure that the opening in the cavity remains sealed.

  • Patent number: 5273178
    Abstract: The invention provides a closable container having an access opening closable by closure doors comprising preferably two hinged doors hingedly mounted on the container on opposed sides of the access opening, and a releasable locking mechanism for the doors. The locking mechanism includes a pair of T-shaped pressure plates hingedly mounted by means of hinge pins on opposed sides of the access opening, to be pivotally displaceable around axes disposed at right angles to the pivotal axes of the hinged doors, to a closed position in which they are positioned over the doors to overlap at least partially with the edges of each door. An engagement block with a handle is provided to hold the pressure plates and the doors in the closed position, the engagement block being rotatably displaceable from a disengaged position to an engaged position in which it engages the pressure plates to exert force on the plates so as to press the edge regions of the doors uniformly against the sides of the access opening.

  • Patent number: 5191991
    Abstract: A fastening which allows a bolted-on cap to part from a body when excessive pressures develop in a cavity in the body, comprises a nut and bolt arrangement, and includes a weakened tubular spacer surrounding each bolt, between the bolt head and the cap. The wall of the spacer is drilled or scored in its mid-length area. The material and proportions of the spacer, and the proportions of the score or drilling, are so matched in relation to a particular pressure environment, that on excessive pressure developing, the load exerted on the cap causes the spacer to collapse in controlled manner, rather than merely crushing or breaking.

  • Patent number: 5119956
    Abstract: An expendable closure assembly is provided for use (in multiple units) with a lockable pressure vessel cover along its rim, such as of an autoclave. This assembly is suited to variable compressive contact and locking with the vessel lid sealing gasket. The closure assembly consists of a thick walled sleeve insert for retention in the under bores fabricated in the cover periphery and the sleeve is provided with internal threading only. A snap serves as a retainer on the underside of the sleeve, locking it into an under bore retention channel. Finally, a standard elongate externally threaded bolt is sized for mating cooperation with the so positioned sleeve, whereby the location of the bolt shaft in the cover bore hole determines its compressive contact on the underlying gasket.

    Abstract: A pressure vessel includes an enclosure adapted to contain a structural assembly in a pressurized environment. The vessel includes first and second enclosure components which together define the enclosure, the first enclosure component is movable relative to the second enclosure component which permits the enclosed pressure to be vented. Structure is provided for coupling between the first and second enclosure components, wherein the structure becomes inoperative when the pressure within the vessel reaches a predetermined excessive level thereby allowing the first enclosure component to separate from the second enclosure component. Structure for limiting the distance the first enclosure component may separate from the second enclosure component is also provided.
