  • Patent number: 9506285
    Abstract: A sealing system for doors and windows includes a reservoir device, a sealing tube configured to expand and to contract, and a transfer valve configured to couple the reservoir device to a first end of the sealing tube. Responsive to either of a door or window closing, a medium may be transferred from the reservoir device via the transfer valve to the sealing tube. Responsive to receiving the medium, the sealing tube may expand to substantially seal a gap between an edge of either of the door or the window and a surface in proximity to the edge. Responsive to either of the door or window opening, the medium may be discharged from the sealing tube via the transfer valve. The sealing tube may contract in response to discharging the medium.

  • Patent number: 8985647
    Abstract: A locking band for use with a container having an annular end portion defining a top opening and a removable cover overlying said opening. The locking band comprises a split circular ring, generally U-shaped in cross section, having first and second ends and including an outer circumferential wall. The second end is of a larger size than the first end to define a handle. A first notch opens outwardly proximate the first end and a second notch opens inwardly proximate the second end. Circumferential spacing between the notches is a select amount greater than a circumference of a cover. A band link has a first end and a second end, each end including a shaft receivable in the respective first and second notches. Spacing between the shafts is substantially similar to the select amount. In use, with the split circular ring surrounding the removable cover and annular end portion, the handle is forced inwardly toward the first end until the handle overlies the first end to secure the cover on the container.

  • Publication number: 20130062893
    Abstract: The present disclosure provides a locking device for restricting access to a hatch of a pressure vessel, and, more specifically, a locking device that is responsive to the internal pressure in the pressure vessel so as to minimize the ability of one to open the hatch while the vessel is still pressurized. In some embodiments, the locking device comprises first and second portions of the locking device configurable between an open and a closed configuration and a pressure-responsive locking member in fluid communication with an outlet port of the pressure vessel and arranged to automatically retain the first and second portions in the closed configuration when the pressure inside of the pressure vessel is above a predetermined threshold, wherein in the closed configuration the first and second portions restrict manipulation of the hatch and/or a locking mechanism of the hatch.

  • Patent number: 6435576
    Abstract: An annular closure ring and bolt assembly for securing a lid or cover in sealed relation with an open-head drum is provided in which an annular split closure ring is closed by tightening a bolt between a pair of laterally spaced lugs attached to opposite ends of the closure ring. Each lug includes a hole to receive the bolt wherein at least one lug hole is unthreaded, and the bolt includes a shoulder or sleeve such that when the bolt is inserted into the unthreaded hole, the shoulder fits substantially flush with that unthreaded hole. The bolt engages either a threaded hole in one of the lugs or a jam nut to draw the lugs together and tighten the closure ring around the drum. The tight engagement between the unthreaded hole of the lug and the shoulder of the bolt thereby reduces movement of the bolt within the unthreaded hole to secure the connection of the ring around the open-head drum.
