  • Patent number: 5947326
    Abstract: A bung comprises a deformable member with a generally cylindrical middle portion generally coinciding with the bunghole when inserted, and upper and lower frusto-conical ends which increase in diameter as each end extends from the middle portion. The middle portion is preferably of a size less than the hole to facilitate insertion of bung into and removal from the bunghole. Where the hole is tapered, the middle portion is similarly tapered. The spool-like shape of the stopper helps to prevent unintentional disengagement of the bung from the hole and to prevent overinsertion of the bung into the hole. The bung may further comprise one or more pull tabs to facilitate removal. The bung may define a bore to allow gas pressure to escape from the container, thus acting as a stopper. A rigid annular insert at the opening of the throughbore prevents deformation of the circular shape of the opening.

  • Patent number: 5145570
    Abstract: The subject invention is a plug for sealing recesses in anode blocks designed to hold anode rods, wherein the anode blocks are intended for the electrolytic extraction of base metals during their calcination treatment. The proposed plug is characterized by the fact that it is die-formed and composed of a material containing cellulose. This provides a very close seal in the anode recess, such that coke granules, which are inserted as fill material to displace oxygen in gaps between several anode blocks within a calcining furnace, cannot enter the anode recesses. Undesirable conglutination inside the anode recesses and burning of the material defining the anode recesses, caused by the unavoidable presence of some oxygen residue during the calcination process, can no longer occur. Because of the great solidity of the plug, deformations of the recesses in the lower rows of anode blocks in the calcining furnace are prevented.

The plug shank includes a frusto-conical surface intermediate a shoulder area and a pair of interconnected cap portions at its free end. A pair of elongated sockets symmetrically disposed adjacent either end of a central reverse cavity are provided with their openings in the head and their closed ends each defined by an elongated cap portion. A hand installation tool includes a bifurcated configured blade providing a pair of blade prongs adapted to be received in the sockets. Upon axial force being exerted by the tool on the cap portions the blade prongs deform the plug such that the shank is effectively drawn through a conforming vehicle body panel elongated slot-shaped aperture with the plug groove sealingly locked to the panel aperture upon removal of the tool.

  • Patent number: 4756852
    Abstract: Disclosed is a method of installing a reversibly porous, air-diffusible, water-restrictive, polymer plug in a port that extends through the wall of a nuclear waste storage container. The plug is inserted a predetermined distance, for example, with the aid of a screwdriver applied to a slot in the plug's outer face. When inserted, the plug prevents the loss of nuclear waste through the port while the air-diffusible nature of the material allows gases to pass through the material. The resultant venting action of the plug prevents the creation of pressure differences between the interior of the container and the environment. Thus, the likelihood of the container becoming overpressurized and leaking is minimized. In addition, the water-restrictive nature of the plug material restricts the ingress and egress of water from the container, reducing the likelihood of groundwater contamination during storage.

  • Patent number: 4690274
    Abstract: A container for generally flat, rectangular electronic components (so-called chips). The container comprises a tubular housing which can be closed on at least one of its ends by means of a closure member. The closure member can be clamped in at least one recess in a wall of the housing. The closure member is in the form of a key having a shaft and a handle. The shaft has, viewed in the longitudinal direction of the handle, a thickness substantially equal to the distance between the wall of the tubular housing provided with the recess and the opposite wall. The shaft has a thickened part in a direction at right angles to the longitudinal direction of the handle. The thickened part has a cross-section substantially corresponding to the dimensions of the recess. Furthermore, the distance of the handle from the thickened part corresponds to the distance of the end of the tubular housing from the recess. Consequently, the key is inserted into the tubular housing and then rotated 90.degree.
