Abstract: A waterproof cover having special utility for a flat or low-slope roof for a building. The roof includes a structural part comprising beams, joists, rafters, etc., as well as a substrate in the form of plywood panels, metal decking, etc. A waterproof cover is secured over the substrate. The cover is formed by placing a plurality of waterproof sheets loosely over the structural substrate, and connecting the abutting edges of adjacent sheets to one another, much like an old-fashion quilt is assembled. The preferred sheets constitute lightweight, thin but relatively stiff sheets of resin-impregnated fiberglass having a thickness of about 0.065 inch; and the joints between adjacent sheets are formed in situ by a mixture of fiberglass fibers and cured resin. The plurality of sheets are joined to one another (along their abutting edges) to form one giant waterproof cover.

Abstract: A hand-held trotline holder adapted for safety accumulating, storing, and dispensing a trotline having a main line with spaced drop lines carrying hooks. The trotline holder includes an arcuate handgrip and spool-like member that rotates with respect to the handgrip. The spool-like member comprises a hollow cylindrical hub with two circular flanges; one of those flanges is attached at each of the two ends of the hub. The trotline is accumulated around the hub and contained between the two flanges. The hub is adapted to rotate about its central (longitudinal) axis, and the two flanges (which are preferably formed integrally with the hub) therefore rotate in planes perpendicular to the hub's central axis. Rigidly affixed to the outer face of the first flange is a series of peripherally and outwardly opening compartments; each compartment has at least one radially extending slot for storing one or more hooks attached to the drop lines.
