US Patent:

45862109, May 6, 1986

Filed:

Mar 11, 1985

Appl. No.:

6/710124

Inventors:

John L. Mueller - Phoenix AZ

International Classification:

A46B 1306

US Classification:

15 29

Abstract:

A washing apparatus includes a centrifugal brake mechanism that limits a rotating speed of a rotary head supporting a ring of bristles, and also includes a mechanism which brings vanes of the rotary head into alignment with a high pressure water jet when the bristles of the washing apparatus are pressed against a surface to be washed. The device prevents excessive amounts of water from being thrown outward by the rotating bristles, yet is small enough to allow scrubbing of hard-to-reach portions of, for example, a car surface.

Abstract:

A VTOL aircraft has a substantially delta-shaped lifting body fuselage with airfoils disposed along all three sides. In vertical flight mode the airfoils act as exhaust diverters. A flow of exhaust gas flows from a centrally located vertical flight gas diffuser over the top surface of the lifting body and then is directed downward by the airfoils to provide vertical lift. In vertical flight mode, the entirety of the exhaust from the engine is diverted to the vertical flight gas diffuser by means of a transition duct that diverts the flow of gas through a 90 upward bend into the vertical flight gas diffuser. In horizontal flight mode the transition duct is fully retracted to permits the entirety of the engine thrust to be directed rearward to propel the aircraft in a horizontal flight mode.
