Abstract: A method of fabricating a structural panel having a predetermined shape in which an inflatable envelope assembly is formed from at least a pair of superplastically formed and diffusion bonded metallic core sheets. The inflatable envelope assembly can be disposed between first and second metallic face sheets which are generally superplastically formed into the predetermined shape prior to being assembled. Thereafter, the assembled face sheets and the inflatable envelope assembly can be superplastically formed and diffusion bonded to form an integral structure, such as structural panel having a compound curvature. Alternatively, the inflatable envelope assembly can be disposed between a pair of reinforced titanium composite sheets. The reinforced titanium composite sheets can also be joined to adjacent face sheets, such as by welding or diffusion bonding, such that an integral structural panel having the predetermined shape can be readily fabricated.

Abstract: The size of a walled ball-court's playing area is changed by moving a wall into and out of one side thereof (e.g., the end of an elongate court). The wall moves on wheels rolling in horizontal tracks inset into the floor of the court. The movable wall is mounted on one end of a frame extending outwards from the ball-court, and the weight of the wall is balanced with counterweights so that the wall does not tip when moved. A mechanical drive, which may be manually powered by a single operator, applies horizontal forces to the wall in order to move it back and forth along the tracks. In a preferred embodiment, two sets of wheels, spaced out along the movable wall, are used. In this configuration the spacing between the two sets of wheels is adjustable to allow an installer to select an optimal spacing.
