Abstract: The outstanding tensile strength of some materials are used in compression applications by using air pressure to supply the outward force on an enclosure and by using interior tension members to maintain the geometry of the air-pressurized structure. The air pressure on each face of the structure is balanced by the tension in the tension members. Due to the high modulus of the tension members, the air-pressurized structures are very rigid. It is the air pressure that actually supports any load placed on the structure, but it is the tension members that maintain the geometry when the load is removed, and the strength of the tension members determine how much air pressure can be sustained. The mass of tension material required in such a structure is roughly equivalent to the amount of filament material required in a cable to support the same load. The Compressed-air Rigid Building Blocks can be stacked like bricks to form strong, lightweight walls, buildings, towers, and other structures.

Abstract: In the manufacture of hollow turbine blades or vanes especially those having a columnar crystalline growth in the alloy, the blade is cast in two opposed halves against a central mold element, the latter being rigid enough to avoid deformation during heating of the mold prior to pouring and during solidification. This central element has on opposite surfaces the configurations of the inner surfaces of the hollow blade. Cooperating with this inner element are outer elements having cooperating inner surface configurations of the convex and concave sides of the blade respectively. After the blade halves are cast simultaneously in the assembled mold and removed therefrom they are bonded together to form a complete blade.
