  • Patent number: 8251238
    Abstract: A closure device includes a door carrying a series of interconnected shear blocks and a keystone shear block designed to transfer stresses created by pressure acting on the door to a surrounding hub. Each interconnected shear block has a limited rotation relative to its adjacent blocks. A holding band operating handle is in communication with a driving link which, in turn, is in communication with the keystone shear block. Actuating the handle causes the keystone shear block to move in an upward vertical direction. The linear movement of the keystone shear block allows the limited rotation of the interconnected shear blocks to occur, thereby causing the circumferential holding band to collapse within itself from an expanded-engaged position to a contracted-removed position relative to said hub. A pressure warning lock provides a safety device and prevents actuation of the holding band operating handle when the pressure chamber is under pressure.

Tracks are disposed on the vacuum distillation apparatus in a position to engage the wheels and raise the lid vertically above a manhole of the vacuum distillation apparatus upon pivotal movement of the lid, which is initiated by nominal physical exertion of a single operator. Extending outwardly from and adjacent the manhole is a flange. The flange has a channel to receive a gasket. A protrusion extends outwardly from a bottom of the lid in a position to extend into the channel and sealably engage the gasket when the wheels disengage the tracts. Clamp assemblies are provided to releasably engage the lid with the flange and draw the protrusion into sealable, releasable engagement with the gasket.

  • Patent number: 6540097
    Abstract: A cooking vessel has a container having an encircling container margin bent outwardly and with a cover having an encircling cover margin bent outwardly. The container can be closed airtight by the cover with the aid of a closing mechanism acting on the container margin and cover margin. The closing mechanism comprises a closure ring extending over the container circumference with a C-profile cross section open radially inwardly, which, with the aid of an actuating mechanism, can be moved from an open position with greater diameter, in which the cover can be lifted from the container, into a closed position with lesser diameter, in which the container margin and the cover margin are clamped together by interspacing a sealing ring between a lower flank and an upper flank of the closure ring.

  • Patent number: 6164481
    Abstract: A spin spray shield connected with a bucket to thereby assist the bucket to retain centrifugal paint spray when a roller is cleaned with a spinning tool, without detracting from the funtionality of the bucket for other purposes. The spin spray shield generally includes an annular shield member for being selectively located selectively substantially entirely above the mouth of a bucket to thereby serve as a shield for retaining spin generated paint spray within the confines of the interior of the bucket, and further includes a guide member located adjacent the side of the bucket for guiding selective movement of the shield member with respect to the mouth of the bucket.

  • Patent number: 5947320
    Abstract: A closure system including a polymeric split ring clamp and a polymeric lid for a polymeric drum. To maintain the integrity of the closure, the lid rim region is formed having an annular restraining notch which cooperates with twist inhibiting blocking components formed within the interior of a cooperating inwardly opening polymeric split ring clamp. The blocking component may be provided as a sequence of regularly spaced block-like protuberances located within the inward upwardly disposed region of the ring clamp. A secondary closure arrangement is provided with the split ring clamp which receives a polymeric banding strap to prevent one end of the split ring from disengaging with an associated pivot arm. When the split ring clamp is in a fully open or pre-clamping mode orientation, a capture groove is formed with the ring pivot shaft formed at one end of the split ring clamp.

  • Patent number: 5941406
    Abstract: The object of this invention is a lidded barrel with a barrel lid and a clamping-ring closure. Between its flat lid plate and its outer rim, the barrel lid is provided with a circular, perimetric groove while also featuring in its periphery at least one bung well with or without a bunghole. When a barrel is dropped, the areas around the bung well are most vulnerable to breakage, i.e. it is in these areas that the barrel lid is most likely to slip out of the clamping ring with leaks resulting. In order to improve leak resistance of a lidded barrel, especially one suitable and approved for hazardous liquids, under extreme stress-load conditions, the area around the bung wells of the barrel lid is to be stress-relieved in the event of overstress (dropped barrel).

    Abstract: The cover is intended for a container with an angled rim and has a sealing mechanism acting peripherally on the edge of the container. There is, around the edge of the cover, an open elastic metal sealing ring exerting a spring force which increases with the diameter of the sealing ring. In its position of rest the sealing ring is clamped between the end region of a part of the rim of the container and the end region of an annular angled section on the edge of the cover. The sealing mechanism comprises means for expanding the diameter of the sealing ring against said spring force.

  • Patent number: 5823340
    Abstract: The invention concerns a sterilization container which is preferably intended for hospital waste and is formed by a bin (1) having a filler opening, which is delimited by the upper edge of the side wall (5) of the bin and is opposite the base (4) thereof, and a lid (2) for covering the filler opening. The bin (1), and possibly also the lid (2), consists of a tough plastics material which is permeable to microwaves and is still resistant to elongation above the boiling point of water. A pressure-tight sealing arrangement (20), disposed between the bin (1) and the lid (2), and a closure arrangement (3, 29), for securing the lid (2) on the bin (1) against the effect of internal pressure in the bin (1), ensure that the contaminated waste collected in this waste-collection container can be sterilized when the container has been hermetically closed and the waste has been moistened by microwave radiation and then disposed of in the sterile state.

  • Patent number: 5713482
    Abstract: A split ring clamp for retaining a lid upon an enclosure such as a plastic or fibrous drum is provided which is formed entirely of polymeric material such as a high molecular weight, high density polyethylene copolymer. The assemblage includes two parts, a channel-form split ring and a pivot arm joining the two ends of the split ring together over the rim structure of a container. One end of the ring supports an integrally formed pivot shaft receiving notch as well as an outwardly extending toe with a rearwardly disposed contact surface. The opposite side of the ring is formed having a receiver channel within which there is provided an inwardly depending toe with a rearwardly facing contact surface. The pivot arm is formed having a transversely disposed arm pivot shaft and a ring pivot shaft receiving notch having a shaft access opening which is outwardly disposed and extends to a shaft bearing surface. Such an arrangement permits a more thin profile for the ring and pivot arm assembly.
