Abstract: A turbine airfoil unit is described which enables an aircraft to ascend and descend vertically. Multiple turbine airfoil units may be arranged within a large disk-like structure and thereby overcome size limitations placed on helicopters by their rotors. One or more central engines providing a flow of air under pressure relative to ambient air supplies power to one or multiple turbine airfoil units. The pressurized air from the engines is funneled into the containing disk-like structure and distributed to all turbine airfoil units encompassed therein. The supplied air acts on the turbines to rotate the airfoils and thus create lift. The lift is transmitted to the disk-like structure and to the remainder of the aircraft by bearings between the turbine airfoil unit and the containing portion of the disk-like structure. The large disk-like structure is known in the popular culture as a flying saucer.

Abstract: The present invention relates to a gyroscopic stabilizer consisting of two interlocking wheels which comprise the field and armature of a synchronous electric motor. The wheels of equal mass and moments of inertia revolve about a common stationary shaft in opposite directions at the same rate of speed. The wheels interlock so that they may revolve relative to each other, but all other motion of one wheel relative to the other is prevented. The total angular momentum of the system is zero. In case of sudden destructive deceleration, no angular momentum is transferred to the stabilized object. Gyroscopic action of the wheels is maximized, and the nongyroscopic mass of the mechanism is minimized.

Abstract: A combined tachometer/gear number indicator, preferably in further combination with a speedometer, is described for use on a motor vehicle for synchronizing engine speeds and vehicle speeds to avoid clutch wear when changing gears. A plurality of coaxial transparent dials carry gear number, engine speed and vehicle speed indicia, and markers are provided for indicating data.

Abstract: A combination trailer and pontoon boat is disclosed in which the supporting wheels are attached to the boat by a confining track. This provides for the controlled launching and landing of the boat while the supporting wheels are fixed in place on dry land. Ramps permit the loading of the towing vehicle onto the boat while both are on dry land. A towing structure moves beneath the boat during loading and off-loading of the tow vehicle and is then pivoted upward in the waterborne mode. The supporting wheels are winched from their position beneath the boat rearward and upward along the confining track in the waterborne mode. The combination trailer and pontoon boat is a towable, one vehicle ferry.
