Abstract: The multi-piston bladeless wind turbine creates electrical energy using hydraulically connected pistons. The system may include a disk, a small piston in fluid communication with a large piston, and a crankshaft attached to the large piston. The disk transfers forces from the wind to the small piston. Hydraulic fluid then transfers the forces to the larger piston. When the disk and associated small piston have been forced to the end of their stroke by the wind, a gate in the disk is opened to reduce wind force on the disk by allowing air to travel through the disk. Subsequently, the disk and associated small piston are pushed back to the beginning of the stroke by the pressure created by the large piston's weight. This process is repeated by closing the gate in the disk. A crankshaft powering an electric generator is turned by the movement of the large piston.

Abstract: A split collar mountable turbine is assembled in two separate halves and circumferentially attachable around existing structures. Top and bottom attachment rings each comprise first and second arcuate elements adapted to interconnect circumferentially about an axis to form two rings formed in spaced relation.

Abstract: A hydraulic power generation system driven by compression air produced by fluid is provided. The present invention is featured in that it employs more than one group of windmills which can be driven by wind power, or utilizes hydraulic power, such as a river flow, tides at estuaries or bays to drive more than one group of hydraulic turbines. The rotation power of the windmills or the hydraulic turbines then drives a transmission and subsequently drives an air compressor to produce compression air. The compression air is compressed with a specific pressure and collectively stored in an air compression tank. The compression air stored in the air compression tank is guided to a water filled hermetic tank. The hermetic tank is connected with a hermetic water tower having a certain height, in which the hermetic tanks and the hermetic water tower are connected with a communicating pipe by which a pressure can be conducted.

Abstract: An air driven fan generator system includes, in association with a fan, a secondary fan, which is mounted coaxially with the fan and with the blades of the secondary fan being relatively closed to the blades of the fan. A generator device is associated with the secondary fan, so that power can be generated by the rotation of the secondary fan due to the movement of the air being passed through the fan. The secondary fan may have the same number, or a lesser number, of blades as the fan, and the pitch of these blades can be such as to provide the required output.

Abstract: A pump stroke is matched to the operating speed of a high speed windmill. The windmill drives a hydraulic pump for a control. Changes in speed of a wind driven shaft open supply and exhaust valves to opposite ends of a hydraulic actuator to lengthen and shorten an oscillating arm thereby lengthening and shortening the stroke of an output pump. Diminishing wind to a stall speed causes the valves to operate the hydraulic cylinder to shorten the oscillating arm to zero. A pressure accumulator in the hydraulic system provides the force necessary to supply the hydraulic fluid under pressure to drive the actuator into and out of the zero position in response to the windmill shaft speed approaching and exceeding windmill stall speed.

Abstract: This windmill head comprises a stub tower having a rotatable platform carrying a wind driven fan which drives a transmission mechanism. The mechanism has two cranks and pitman arms at opposite sides driving two rocking beams carrying counterweights. One beam is coupled to a vertical pump rod by non-rigid members to reciprocate the pump rod. The counterweights assist the beams in pulling up the pump rod and pumped load. A tail assembly tracks the wind by rotating the platform so that the fan faces the wind. The fan furls out of the wind when wind speed is excessive. A power unit may drive the transmission mechanism when wind speed is too low and high to drive the fan. The platform is carried by bearings which prevent vertical movement of the platform and components on it while the pump rod is being pulled up and pushed down, and while the counterweights are raised and lowered. The power unit can generate electric power when the wind speed is high enough to drive the fan.

Abstract: A water pump includes a pump stand and a spout mounted on the stand for communication with its interior. A rotary drive shaft supported by the pump stand extends downwardly to an underground water supply. A pump rotor supported by the drive shaft is positioned within a stator communicating with the water supply, for cooperating to pump water to the pump stand and the spout. An input shaft applies a rotary driving motion to a gear box mounted on the pump stand, which in turn applies a rotary driving motion to the drive shaft. The gear box includes first and second bevel gears mounted on the input shaft in a spaced apart relation. A first clutch permits relative rotary motion in a first direction between the input shaft and the first gear while prohibiting relative rotary motion in a second direction. A second clutch permits relative rotary motion between the input shaft and the second bevel gear in the second direction, while prohibiting relative rotary motion in the first direction.

Abstract: An apparatus adapted to be connected in a drill string is disclosed. It utilizes an axially located turbine which is driven by the mud flow through the drill string. The turbine is supported by a shaft and connected to an appropriate gear train. The gear train rotates an outer sleeve which has multiple turns of an external screw thereon. The screw or helix extends toward the wall of the drill bore. The helix lifts the column of mud in the annular space above the drill bit away from the drill bit thereby reducing the back pressure just above the drill bit. This improves the jetting action of the mud pumped through the drill bit and provides for a more rapid excavation of the immediate vicinity, thereby increasing the rate of penetration of the drill bit.
