Abstract: A boat or ship (marine vessel) can be powered and propelled by using wind or solar energy. This propulsion results in the forward movement and six degrees of motion (roll, heave, pitch, yaw, surge, and sway) of the marine vessel. These motions have kinetic energy. This invention capitalizes on the fact that the solar wind and wave energy are cyclical by nature. The present invention enables the vessel to store energy harvested from these energy sources during periods when levels of energy is available from wind, solar, or the motion of the vessel in waves. This invention makes this stored energy available for use during periods when the external natural sources of energy (wind, wave, or solar) are not available in adequate quantities to maintain a reasonable speed of advance for the marine vessel. The harvesting of the energy during high energy cycles, storing it and using it when needed in this invention allows a marine vessel to get maximum speed of advance over a course.

Abstract: A hybrid engine including a set of sequencing generators, an electric motor, and a rotary internal combustion engine, including pivotal vane elements mounted on a rotor and biased into engagement to sequentially form intake, compression, combustion and exhaust chambers between the rotor and its housings annular inner wall.

Abstract: A power unit includes two or more power modules (1, 2, 3), each comprising an engine (11), a transfer case (12) connected to the engine (11) and a hydraulic pump set (13) connected to the transfer case (12). A controlling method for the power unit is also disclosed. Compared to the prior art of using a single super high power engine, the hydraulic mobile crane using the in power unit has advantages of low cost, high reliability, and not being subjected to the restrictions by road transportation conditions during transportation.

Abstract: A wind-energy and radiation-energy collector system has at least one radiation-energy collector with a radiation-absorbing absorber and a reflector element. The reflector element collects radiation and directs the radiation at the absorber. At least one wind wheel, which is arranged in a direction opposite the receiving direction of the radiation-energy collector and which is supported on the system, is provided. The arrangement of the radiation-energy collector and the wind wheel is movably supported so that the arrangement can be oriented either with the radiation-energy collector facing the sun or with the wind wheel against the prevailing wind direction.

Abstract: The present invention is a new and novel wind generator system particularly suitable for small wind applications that harnesses low velocity wind effectively. In a preferred embodiment of the invention, the wind generator system comprises a drive shaft; one or more retreating blades and one or more advancing blades attached to the drive shaft and extending radially outwardly therefrom; a generator assembly coupled to the drive shaft and effective for generating electrical power; and a housing having an inner chamber for receiving the blades and a wind directional apparatus that operates to adjust the speed of the wind and to channel wind along a desired flow pathway towards the one or more of the retreating blades and blocks airflow from impinging on one or more advancing blades.

Abstract: A hybrid engine including an electric generator, an electric motor, and a rotary internal combustion engine including pivoted vane elements mounted on a rotor and biased into engagement to sequentially form intake, compression, combustion and exhaust chambers between the rotor and its annular wall.

Abstract: A set of independently usable linear drive, which include at least one fluid power and at least one electrical linear drive. The principal housing bodies of the linear drive are respectively provided with an elongated receiving space, in which fluid power drive means or electrical drive means are located dependent of the type of drive. As regards their outer shape the principal housing bodies at least essentially the same and their receiving spaces possesses the same cross sectional form. Accordingly on the basis of a large number of the identical component different types of linear drive may be produced.

Abstract: A special purpose helicopter based on an existing airframe, power train, and engine, modified to provide greatly enhanced performance, payload, speed and maneuverability. The modification consists of modifying an original helicopter universal transmission center case for installation of twin drive shafts, at 180.degree. apart, and mounting a second engine on the airframe structure, at 180.degree. to the first engine, and forward of the transmission. An exhaust system for the second engine is split into two units for directing the exhaust outwardly and upwardly.

Abstract: A gas turbine plant including one or more gas turbine units comprises a base member formed like a box having square end walls and four side walls joined thereto. An output shaft is journalled centrally in the end walls and carries a gear wheel, the diameter of which is slightly less than the side dimensions of the end walls. The rotor shaft of the gas turbine is, at least partly, enclosed in a housing component having a base portion adapted to be mounted upon arbitrary side wall of the base member. Two gear wheels are mounted upon a lay shaft in the housing. One of these gear wheels meshes with a gear wheel upon the rotor shaft, while the other gear wheel, when the unit is mounted upon the base member, meshes with the gear wheel enclosed therein.

Abstract: An energy conversion apparatus and method for the transfer and utilization of kinetic energy received by one or more natural kinetic energy receptors from one or more "natural kinetic energy source" such as for example solar energy, wind energy, water currents and tides, geothermal energy and the like, for powering one or more electricity generating devices. The "natural kinetic energy" is converted into fluid pressure by "receptor(s)" coupled with hydraulic fluid pressure pump(s). Back flow of fluid is prevented from flowing through the non-operating fluid pumps by check valve(s). The fluid pressure is used to operate one or more fluid pressure motors coupled with electricity generating unit(s). When first and second fluid pressure motors are used, means is provided for directing all of the fluid under pressure through the first pressure motor until it is operating at a desired speed before fluid pressure is permitted to operate the second pressure motor.

Abstract: A surge tank for a plurality of pneumatically operated motors which impart motion to a machine. The tank comprises at least one portion of a support table for the machine.
