Abstract: A variable shaped wheel having a hub, a plurality of extendable ram rods connecting the hub and shape adaptable rim. Extension and retraction of the ram rods cause the rim to harmonize to a selected wheel shape such as horizontal oval, vertical oval, elliptical, tractor like and numerous other shapes, when stationary and while moving. The selected shape of the variable wheel in motion is maintained by continual length adjustment of the ram rods. The variable shaped wheel adjusts to the most effective, efficient shape for travel over varying surfaces such as asphalt, concrete, sand, mud, rock, snow, ice and others, providing optimum speed and comfort.

Abstract: An article of insulation and its method of manufacture, in which a planar sheet member has a plurality of score lines (24--24) made in the exterior surface thereof, and is then folded along the score lines (24--24) and then sealed to form an enclosed, airtight volume. Positioned between the upper and lower portions (12,14) of the sheet member are a plurality of thin, flexible, resilient, spaced interior elements (36--36). The combination is deformed to form corrugated surfaces and then expanded so that the upper and lower portions are spaced apart and the interior elements are again substantially flat. The space between the upper and lower elements is evacuated.

Abstract: An article of insulation and a method for making same. Outer sheet-like elements (22,24) of elastic deformable material are secured by adhesive to a base element (20) of rigid deformable material in a particular pattern which defines unbonded areas which are each bounded entirely by adhesive. The combination of the two outer elements (22,24) and the base element (20) is then deformed, following which the base element (20) retains its deformed shape while the outer elements (22,24) spring back to their original shape, leaving voids between the base element (20) and the outer elements (22,24) in which there is a partial vacuum.
