Abstract: A building aperture cover reinforcing device includes a support post having a first end spaced apart from a second end by a middle portion. Engagement pins extend from each end of the post, and linking hooks extend from the middle portion of the post. An upper anchoring assembly adapted for securement to an upper boundary wall of a building aperture selectively maintains the first engagement pin in a securing orientation, while the second engagement pin is selectively held in place by a lower anchor plate. The linking hooks engage corresponding linking plates disposed on the selected aperture cover. Each engagement pin includes bracing notches that engage corresponding edges of pin apertures located within the anchoring assembly and anchor plate, when the post shifts laterally. The bracing notches prevent vertical motion of the post during negative wind loads and positive wind loads.

Abstract: A collapsible tent comprising a closed loop resilient coilable tent member, the member being distorted to form at least three tent support nooses, each tent support noose adjoining the other tent support nooses along at least a portion of its perimeter. The tent support noose having a perimeter substantially the same as that of the other tent support nooses and a tent membrane attached to at least a portion of the perimeter of the tent support noose and extending between the opposing portions of the tent support noose to restrain the tent support noose. A common adjoining region loop member secured within the tent membrane. A collapsible hat includes a closed loop resilient coilable hat member, and a hat membrane attached to at least a portion of the perimeter of the hat member. The hat member forms a common adjoining tent region for the tent support nooses.

Abstract: A preformed coving (1) suitable for casting into a bund wall (69), said coving (1) including: a base portion (3) positionable on or in close proximity to a floor (37) and having a concave curved front face (5) and a dependent flange (11) adapted for location in a recess in said floor; a wall portion (7) having a front face (9); and attachment means (23) remote from said front faces adapted to receive a fixing device (47) for securing said coving (1) to said floor (37). The coving (1) may further include support means (31) to receive a support and/or spacer element (57) to support a reinforcing rod (67) to be cast into the bund wall (69) or to space one coving from another when the bund wall (69) requires a coving on each of its sides.
