  • Cargo carrying air vehicle
    Patent number: 8544797
    Abstract: A system for controlling the lift of an airship for carrying a cargo and a supply of fuel has a self supporting hull made of a flexible gas impermeable material. Air which is located in the hull is at an internal pressure which is greater than the atmospheric pressure of the air on the outside of the hull, and a bag filled with helium is located within the hull and is surrounded by the air in the hull. A heating means is provided to heat both the air and the helium. The bag located within the hull and surrounded by the air in the hull has enough helium in it at ambient temperature to lift all but the cargo and fuel in the airship, and the air and helium, when heated, provides increased buoyancy due to the increase of expansion of both heated gases to lift the airship with its fuel and cargo.

  • Article of and method for forming a generally orthogonal corner arrangement having no external fasteners or protrusions
    Publication number: 20110272312
    Abstract: A box for holding a book or object having orthogonal corners wherein each corner includes a first surface having a bent ear, a second surface having a fold over flap and a third surface that is formed when the fold over flap of the second surface is folded over the bottom and top edges of the bent ear. The end of the fold over flap has tabs at its end which engage tab receptors which are located in the third surface before it folds over the bottom edge of the bent ear. The tab receptors are cavities which extend only partially through the third surface.
