Abstract: A system and method for simplified construction and erection of planar devices such as walls comprises two types of steel channel members twisted together at right angles to form a tight, weldless and fastener-less connection. Slots in one member mate with flange elements of the other member to form the tight connection. Both steel members may be cold rolled from flat steel stock, the mating slots being cut into the flat steel stock prior to rolling. Though the resulting connections rely upon the strength of the steel itself instead of fasteners or welds, auxiliary screws or other fasteners optionally may be employed to prevent untwisting of the members after installation.

Abstract: Apparatus and method for constructing at a given site a building having a predetermined shape with a periphery that is essentially defined by a width and a length, and the building having generally vertical walls. At a second site creating an upright structure having an interior bounded by spaced-apart and generally vertical walls but no floor, the separation of said walls serving to define an empty shell whose size and shape corresponds to that of the building that is to be constructed. Connecting horizontal beams to the interior of the upright structure so that they and the upright structure can be lifted. Positioning inside the upright structure a trailer that has the necessary load capacity to transport the upright structure over a public road. Temporarily connecting the trailer to the horizontal beams and transporting the upright structure to the first site. Disconnecting the trailer from the upright structure and removing the trailer from the interior of the upright structure.

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: Tilt-wall concrete panels adapted for constructing small buildings with "finished" interiors, especially single-family residences, etc. A peripheral frame of wooden members is laid on top of a barrier film of plastic (e.g., 4 mil polyethylene) on a horizontal surface. Wood-like studs are then placed within the frame and nailed thereto. Any desired utility cables and service pipes are positioned within the frame. An insulating foam cover, preferably high-density polyurethane, is then generated within and over the frame, to a depth that at least covers the wood-like studs and any utility or service lines. Foam about 1.5 inches thick will cover these elements and bond them securely together as a stable, easily movable "plate"--after the foam plastic has hardened.

Abstract: A fishing rod holder assembly (10) is provided for attachment to the side of a boat (14) or the like. The assembly (10) comprises a base (18) of a size and shape to be mounted in a recess position in the side of a boat and a rod engaging body (16) releasably attached to the base by a clamping assembly (19). The body has a socket portion (46) for engaging the pistol grip of the rod. The body (16) varies in thickness in the area engaging the assembly (19).
