Abstract: A spherical rotary machine which may be embodied as a pump, internal combustion engine, compressor or similar other device includes an outer shell with a substantially spherical interior surface, an inner shell including a substantially spherical outer surface centered within the outer shell, and six rotary pistons located between the inner and outer shell. Each piston is rotatable about its own central axis, the six axes being orthogonally centered on the center of the machine. Each piston includes a top convex spherical surface conforming substantially in shape to and located adjacent to the spherical interior surface of the outer shell, a bottom concave spherical surface conforming substantially in shape to and located adjacent to the spherical outer surface of the inner shell, and an oval conical side surface which is substantially defined by lines which are substantially radial with respect to a point near the machine center.

Abstract: A magnetic field transfer device includes a pair of oppositely wound inner coils which each include at least one winding around an inner coil axis, and an outer coil which includes at least one winding around an outer coil axis. The windings may be formed of superconductors. The axes of the two inner coils are parallel and laterally spaced from each other so that the inner coils are positioned in side-by-side relation. The outer coil is outwardly positioned from the inner coils and rotatable relative to the inner coils about a rotational axis substantially perpendicular to the inner coil axes to generate a hypothetical surface which substantially encloses the inner coils. The outer coil rotates relative to the inner coils between a first position in which the outer coil axis is substantially parallel to the inner coil axes and the outer coil augments the magnetic field formed in one of the inner coils, and a second position 180.degree.
