Abstract: A visible record loose-leaf binder for pages of strip sheet material arranged in partially overlapped fashion has a hinged cover to which are attached L-shaped members having a plurality of prongs thereon. The prongs extend through perforations in the sheet material to maintain the sheets in the binder. Sets of compensating pads having increasing height from the center of the binder to its upper and lower edges are provided to maintain the overlapped sheet material in substantially flat configuration when the binder is closed, and also provide a flat writing surface when the binder is opened. The L-shaped members are hinged together and held in opposed relation by a band surrounding the members. The band may have an internally or externally accessible locking means for opening and closing thereof.

Abstract: A multiple panel container especially useful for compost tanks, grain bins, and the like storage constructions has pairs of hinged together corner forming panels overlapping with each other or with insert panels. The panels have a plurality of spaced recesses along the width thereof to be aligned at the overlap and receive fasteners fixedly securing the panels together to form the perimeter of an enclosure of desired size which can be covered with a tarpaulin supported from expansible and contractable trusses. The panels can be arranged to provide compartments in the enclosure and to provide access doors. The panels can be folded flatwise and stacked in a compact pile when not in use. The panels can be composed of plywood, metal, sheet plastic material or the like.
