Abstract: A rotational damper for a motor vehicle, includes a gyro element which includes a first shaft mounted such that it can be rotated with respect to a first component and is connected to a second component which performs a relative movement with respect to the first component, wherein the first shaft has a frame, in which a second shaft lies orthogonally and is mounted rotatably, wherein the second shaft has a frame, in which a third shaft is mounted orthogonally with respect to the second shaft and such that it can be rotated in the second frame, wherein the second shaft and the third shaft are each connected to a shaft drive, and the third shaft has an inertia weight, wherein a rotation of the second shaft by the second shaft drive brings about a change in the angular velocity or the moment of the first shaft which is connected to the second component.

Abstract: The vehicle can be referred as a type of speedboat, because it is designed for very high speed on water. Preferably, the vehicle consists of a hollow shell 1 of circular section that floats and spins on the surface S of the water. The engine 2, which also includes the cabin, is located inside the shell 1. The output shaft of the engine 2 drives the shell 1 about axis O. As the shell 1 spins, the viscous forces between the spinning surface of the shell and the liquid, cause movement of the vehicle. Means of preventing counter rotation, of the engine 2 inside the shell about axis O are included. This is provided by the weight of the engine, which hangs low and off-centered about axis O; and by the aerodynamic uplift acting on the tail 3, through the lever arm action on the frame of the engine 2.

Abstract: The invention accesses an inexhaustible energy source of the ocean to produce ship propulsion and to generate electrical energy.

Abstract: A hydro-rotor for providing propulsion or generating electricity in a device positioned in water. A hollow tank having a forward and aft tapered end in the preferred embodiment is mounted about a longitudinal axis to a pair of stabilizer plates. A helical flight is mounted circumferentially to the tank and extends from the forward end to the aft end of the tank. An electric motor and power source within the tank drivingly rotates the flight thereby propelling the tank through water. A pair of stabilizer plates extending outwardly of the flight and along the length of the longitudinal axis are controllingly pivoted to radial positions providing directional stability to the craft. The hydro-rotors may be rotatably mounted utilizing stabilizer plates to a ship providing propulsion therefor.

Abstract: A marine craft comprises an outer hull of completely spherical shape, an inner hull of hemispherical shape, universal bearings between the inner hull and outer hull supporting the inner structure in the outer hull and permitting universal movement, and a mass in the inner hull biassing it into a reference position. A plurality of spaced apart groups of four fins are provided on the exterior of the outer hull to procure propulsion of the craft along the surface of the water on rotation of the outer hull about any diametric axis. The four fins of each group are joined to each other in a generally cruciform configuration. The fins of any one such group are coplanar with a first pair of mutually perpendicular diametric axes of the outer hull while the fins of another one of such groups are coplanar with a different pair of mutually perpendicular diametric axes.

Abstract: A multidirectional amphibious safety vehicle comprises an outer cylindrical shell having two opposite ends and a longitudinal axis therethrough; a stationary central pipe having two opposite ends and extending along the longitudinal axis of the outer cylindrical shell; elements, secured around the central pipe, for rotating the outer cylindrical shell about the central pipe whereby the safety vehicle moves forward and backward over land, water, and other terrain; and a motor, mounted on at least one of the two opposite ends of the central pipe, for driving the safety vehicle sideways on water.

Abstract: A buoyant apparatus for transport or amusement which is propelled by a human operator in a standing position. An annular float has a platform secured to its upper side and a plurality of circumferentially spaced fins extending from its lower side. Struts with pontoons are removably connectable to a rotatable mast which extends through the platform. When a human operator strands on an outer ring portion of the platform, the pontoons float in the water and stabilize the annular float in an inclined position, raising the fins on one side of the float out of the water. When the operator walks forwardly, counteracting the torque by holding a paddle against a strut, forward propulsion results. When sufficient skill is acquired, the struts and pontoons are disconnected from the mast, and the operator drags the buoyant paddle in the water to provide balance and counteract torque sufficiently to result in forward propulsion.
