Abstract: A flyable automobile comprising a right main wing connected to the flyable automobile and comprising a right wing inner portion and a right wing outer portion, the right wing outer portion hingedly connected to the right wing inner portion so that the right wing outer portion can be folded above the right wing inner portion, and the right main wing connected to the flyable automobile so that the right main wing can pivot into a storage compartment underneath in the flyable automobile, and a left main wing connected to the flyable automobile and having a left wing inner portion and an left wing outer portion, the left wing outer portion hingedly connected to the left wing inner portion so that the left wing outer portion can be folded above the left wing inner portion, the left main wing connected to the flyable automobile so that the left main wing can pivot into the storage compartment in the flyable automobile.

Abstract: A fluid stream solids separator provides a curved flow confining chamber to cause heavier constituents in a fluid stream, or slurry, flowing in the resulting curved path in the chamber to migrate radially outward with time and distance travelled. At least one skimmer blade is provided to protrude some distance into the stream from the radially outer flow boundary. The blade skims a strata of the heavier constituents from the stream and directs skimmed products into a separate exit flow path. A series of skimmer blades can be used to skim consecutive strata from the main stream. Fluid flow confining chambers of both mushroom and cylindrical shape are provided. Adjustment means, optionally provided, move the input guiding surfaces to change velocity and move the skimmer blades to change the thickness of strata extracted from the main stream.
