Abstract:
A transportable pantograph truss bridge structure. The pantograph truss is in the form of an inverted triangle with deck sections incorporating gratings utilized as parallel tracks for wheeled vehicles. The bridge is suitable for rapid deployment in military applications and is portable on a wheeled trailer including erecting masts, cables, and winches. The pantograph truss is formed of sealed tubular elements, so as to be neutrally buoyant. The deck panels are formed in sections with grating formed of metal or of resin impregnated Fiberglas, carbon filaments or the like.
Solar Oven
US Patent:

Abstract:
A hemispherical oven body is formed from two concentric, spaced apart hemispherical shells having thermal insulation between and with spacing maintained by thermally insulating spacers in a triangular array. A single elongated fastener through the center point of each shell holds the shells together and provides a sighting point for aiming the oven at the sun. The shell edges at the oven face are closed by a resilient seal ring that extends above the shell edges and contacts a cover disk of glazing material. Combination hinge/handles are located at diametrically opposite sides of the cover disk, and a hinge pin on an edge of the oven body engages one of the handle/hinges. A reflector panel assembly includes a closed geometric figure formed by hinge rods connected at opposite ends to common anchors, which connect the hinge rods to the cover disk. The reflector panels pivot on the hinge rods to fold against the cover disk. A cross member formed from intersecting rods holds the reflector panels in operative position and cooperates with the fastener between the shells in providing a sighting aid for aiming the oven.
