Abstract: Disclosed is a secure shelter for housing at least one individual for a sustained period during and after a natural disaster event. The shelter comprises a hardened enclosure having a securable hatch access door, an interior cabin and at least one user seat with a full safety harness. Each seat is preferably attached to the enclosure walls and may include an energy attenuating connection, while life supporting elements within the cabin include lighting, air filtration and intake means, communication and locating means, storage for supplies, as well as a power supply for sustained and independent operation. The device is preferably positioned within the basement of a home and tethered to a structural wall, or alternatively is affixed to the ground using structural footings when in use outside of a mobile or trailer home. The device protects users and maintains a comfortable, survivable environment during and after a natural disaster event.

Abstract: A release assembly for operating a remote mechanism such as a subsea well connector includes a funnel-shaped body adapted to engage the well connector and a movable arm adapted to engage and disengage a locking cap of the well connector and provide lifting force in order to actuate the locking cap.

Abstract: This invention relates to an improved gate valve having floating seal elements which are back-relieving and reversible for long-term permanent sealing under varied pressure conditions. The sealing elements are mounted in unrestrained relation in juxtaposed recesses in the fluid passage facing the movable gate with annular gaskets facing both the gate and the recesses for improved self-aligning sealing engagement therewith. The sealing elements and their annular gaskets may be reversed, interchanged, or readily replaced as desired, the valve structure being especially useful for inherently fail-safe slab type gate valves.
