Abstract: An upright-wall, ceiling or roof made of panels fastened together along contacting panel edges. Each panel is made of a can-supporting planar element (a sheet of plywood, masonite, plastic or the like), reinforcing bars defining outer edges of the panel, cans between the reinforcing bars, wide-mesh wire or plastic panel-reinforcing network on the cans, and molded matrix material (foamed, cellular, polyolefin plastic, or concrete of portland or other cement and sand or porous aggregate -- for example, cinders, vermiculite, pumice, charred sawdust or the like) on the cans. The can-supporting element is placed in a mold, cans are put on this element optionally parallel to it but with their axes preferably perpendicular to it, the wide-mesh network is placed on the cans, and the moldable plastic material in fluent form is poured or injected into the mold thru the wide mesh of the network around the cans and on the network.

Abstract: A winged aircraft, adapted to takeoff and land with its longitudinal axis at a very steep angle of inclination, including: balloons that have a center of buoyancy forward of the center of gravity and tend to turn the craft into the said steep angle; a controllable-thrust stern-elevating propeller in an upright wind tunnel, having a lift rearward of the center of gravity that in horizontal flight balances the torque of the balloons; and an elongated, stiffly resilient body frame of a multiplicity of inflated small tubes extending in the fore-and-aft direction, supported by longitudinally spaced, rounded ribs, disks or the like. This frame is round in the middle and somewhat streamlined at each end, its stern portion rearwardly sloping downward at its top and upward at its bottom. The assembly of tubes, preferably extending from the foremost to the rearmost parts of the frame, is flattened into substantially linear, horizontal shape at the rear portion.

Abstract: A low-cost building, building section or wall, usable as a house, mobile home, vehicle, or part of these or other structures, having numerous parallel rows of end-joined used or new cans, each can preferably consisting of a tube and can-cover elements at ends of the tube and containing thermal insulation, which may be only dead air in the relatively small hollow can space but preferably includes loose small portions of low-cost insulating material, such as sawdust, vermiculite, cotton linters, dry sand or dust, ashes, cinders, ground bark, rice or other seed hulls. Abutting pairs of can cover elements are tightly held together by connecting means which may be bonding material (epoxy putty, solder or the like) or bands of slightly stretchable adhesive tape which encompass and adhere to portions of juxtaposed pairs of the end-joined cans. A layer of mesh sheathes one side of each group of the can rows, and the other side is sheathed with wall material which may be mesh or insulating solid panels.

Abstract: A construction member including a row of cans and a pair of channels of mesh or the like, housing and holding the cans together. Each of these channels includes an elongated middle piece of the mesh and an elongated lateral piece on each side of the middle piece, angularly and integrally joined to the middle piece. The pair of opposite lateral pieces on each side of the can row meet at middle portions of the cans, and one of this pair has elongated edge portions which overlap edge portions of the other lateral piece of the pair. Fastening means (screws or other rod-like elements and/or epoxy putty or the like) pass thru the lapped edge portions on each side of the can row, and when, as is preferable, screws are utilized these are screwed into material of at least the end cans of the can row, thus holding the mesh channels together and the cans within the channels. The cans preferably contain low-cost insulation.
