摘要： This invention relates to an internal-combustion engine of generally spherical configuration having a generally spherical rotor mounted on a rotor shaft in a generally spherical shell. Combustion chambers are formed in appropriate recesses in the rotor and the inside of the spherical shell. The recesses are bounded by fixed partitions and movable pistons between the fixed partitions so that a series of combustion chambers are formed one on each side of each piston. The pistons are each connected to a central hub at the center of the rotor, and the hub is rotatable to a limited extent in a direction perpendicular to the rotor shaft. The pistons are therefore able to sweep through limited angular motion and during each motion increase the volume of one series of combustion chambers and decrease the volume of the other series of combustion chambers. A mechanical activating mechanism is provided so that the central hub is caused to rotate in a reciprocating manner through various angular positions that are predetermined in relation to the angular position of the rotor; in this manner the piston sweeping motion is precisely linked to the angular position of the rotor. Appropriate ports and ignition components are provided so that fuel and air can enter the various combustion chambers in proper sequence, be compressed, burned and exhausted also in proper sequence.

摘要： A planar writing surface is attached to a vertically arrangable support panel for engagement next to an automobile console. The support panel has a pair of side edges which each have a vertically adjustable support leg thereon. Each support leg may be independently heightwise adjustable to each touch the floor of the auto next to the console, and provide rigidity to the writing surface. The writing surface panel may flip onto the support panel through an arc of 270 degrees, about its common hinge.

摘要： A composite tube for a gun barrel and a method for making the tube are disclosed. The tube includes a plurality of elongate carbon fibers and a resin material surrounding a longitudinal bore axis. The elongate carbon fibers are aligned parallel with the longitudinal bore axis and are under compression along the longitudinal bore axis. Such a tube for a gun barrel may be made by wrapping a tubular metal liner with a resin matrix material containing a plurality of elongate carbon fibers, and aligning the carbon fibers parallel with the longitudinal axis of the liner. The resin matrix material is cured, and the elongate carbon fibers are placed under compression along the longitudinal axis of the liner. Compressing the carbon fibers along the longitudinal axis of the liner produces a tube of surprising stiffness. The tube provides a highly stable gun barrel of reduced weight for good accuracy.
