Abstract: In one example, a portable expandable shelter includes an enclosure with one or more movable portions such as a side or end, and further includes a foldable frame configured and arranged for operation in unison with movement of the movable portion of the enclosure. This example of the portable expandable shelter also includes a cover that encloses at least a portion of a space defined by the movable portion and the foldable frame.

Abstract: A fluid controlled containment berm system for automatically forming a containment berm to contain hazardous liquid spills. The fluid controlled containment berm system includes a liner including a floor and a sidewall, a buoyant member attached to an upper portion of the liner, and a pair of diffuser members attached between the floor and the sidewall.

Abstract: Containment berms and associated support systems and structures. In one example embodiment, a containment berm bracket includes a substantially rigid first member and a substantially rigid second member. The first member defines a first complementary structure. The second member that defines a second complementary structure and a sidewall clamp. The second complementary structure is configured to releasably engage with the first complementary structure in order that the members can be releasably attached to each other.

Abstract: A bladder support system for reducing the stresses placed upon a bladder unit. The bladder support system includes a bladder unit fillable with a fluid, a base member comprised of a sheet structure, wherein the base member is positioned adjacent to the bladder unit and a plurality of straps attached to the base member. The plurality of straps are comprised of an elongated structure and removably attach the base member to the bladder unit in such a manner in which the plurality of straps and the base member encompass the bladder unit.

Abstract: A coil cap cover for a cylindrical coil of aluminum stock provides round portion 20 sized to fit either end of the cylindrical coil of aluminum and a substantially rectangular attached skirt portion 60 which covers an adjacent portion of the cylindrical sidewall of the coil. A welded region 70 connects a perimeter edge of the round fabric portion to an upper edge of the fabric skirt portion, creating a three-dimensional coil cap. An overlap weld 80 fastens the upper edges of the ends of the skirt portion together with a segment of the perimeter of the round fabric portion. A crimp weld 90 fastens a lower corner of each end of the skirt portion together. In a preferred version of the invention, an overhang region radially outward from the welded region provides a plurality of curved blades separated by curved notches. A portion of each blade may be folded over the edge of the coil, depending on the diameter of the coil.
