    摘要： A foot propelled two-wheel-in-line vehicle having a two-wheel friction drive including a front drive epicyclic contra-rotating element, pedalled driving wheels, a pedal actuated rear wheel brake, and an automatic variable-speed transmission comprising a centrally disposed rotor in friction-tight contact with a plurality of pulley wheels normal thereto and radially traversing thereon, said wheels flexibly connected with mating wheels and with said epicyclic element in such manner as to impart torque to the perimeter of the cycle wheels.

    摘要： A convertible auxiliary turbine capable of providing turbopropeller thrust interchangeably with pure jet propulsion, comprising a controllable fluid deflector element, and an inverted free-floating rotor having planular drive-vanes aligned with the normal flow direction of the engine's gas stream. Thus, no rotative force is imparted to the turbine until the flow direction is varied. At a given change, the turbine begins to spin, outboard swingable propeller blades are urged to open by action of centrifugal force, and propeller thrust is generated in ratio to the angle of deflection, with jet power in inverse ratio thereto.
