  • Patent number: 4039847
    Abstract: A device and method of converting tidal currents into power. The device comprises a plurality of modules and is mounted in tidal water so that one face is presented inland and the opposite face is presented seaward. Each module comprises a turbine mounted on an elevator means which moves the turbine vertically in response to water level changes during a tide. The modules are alternately presented toward the inland and seaward directions thereby permitting tidal water movement associated with both flood and ebb tides to be converted into power. Apparatus for sensing the amount of water flowing over the turbine for controlling the movement of the elevator device, and apparatus for withdrawing power from the device are also disclosed.

  • Patent number: 4035658
    Abstract: A high power wind turbine with kinetic accumulator is disclosed. The invention includes a circular wall, a wall turbine movably mounted to the circular wall so that it can be moved to face the wind, a non-linear generator connected to the wind turbine to generate electrical power, a fly wheel, and a drive wheel disposed in contact with the fly wheel to drive the fly wheel. A reversible non-linear motor is connected to the drive wheel to drive the drive wheel or to be driven by the drive wheel. The non-linear generator is connected to the reversible motor to rotate the drive wheel to rotate the fly wheel when the non-linear generator generates excess electrical power. The fly wheel rotates the drive wheel to drive the reversible motor to generate electrical power when the non-linear generator does not generate sufficient electrical power.

  • Patent number: 4033528
    Abstract: A parachute system removably mounted on an aircraft. The system comprises a container removably and releasably attached to an aircraft fuselage. The container has a lid which is biased open and a locking mechanism which maintains the lid closed until a parachute is to be deployed. A drogue chute ejecting mechanism ejects a drogue chute when the lid is opened, and the drogue chute deploys a main chute stored in the container and which is connected to the container. A coupling attaches the container to the aircraft fuselage and is disconnectable so that the chute system can be jettisoned from the aircraft.

  • Patent number: 4031695
    Abstract: A hedging apparatus is disclosed which comprises a wheeled vehicle having a specially adapted chain saw thereon for cutting limbs and branches from trees, hedges, or shrubs, which are planted in rows. The chain saw is provided with a plurality of spaced-apart guide bars which extend forwardly of the cutter chain, thus assuring the severing of limber branches which would otherwise be pushed aside by the saw and remain uncut. Resilient springs in the form of elongated rods can be used in conjunction with the guide bars to prevent chattering of the branches being cut. To particular advantage, a positioner can be provided for setting the chain saw blade at a selected pitch angle and for maintaining the selected pitch angle during a hedging operation. To further advantage, a hopper can also be provided for collection and disposal of the severed limbs and branches during the hedging operation so that they do not have to be subsequently gathered up and hauled to another site for disposal.

  • Patent number: 4030890
    Abstract: An apparatus and method for separating hydrogen and oxygen from water molecules. A solar reflecting means reflects solar energy onto a water containing tank to boil water contained therein and form steam. The steam is transferred either to a turbine-generator assembly for producing power, or to a dissociating means for producing hydrogen and oxygen. The steam in the dissociating means is forced to traverse a spiral path wherein it undergoes a circular motion to subject it to centrifugal force while contacting a heat transfer surface. Solar energy is concentrated on the heat transfer surface and heat in amounts sufficient to raise the temperature of the steam to the dissociation temperature thereof is transferred thereto. Hydrogen and oxygen are separated from each other by the centrifugal forces, and are withdrawn from the dissociating means. An electric starter and means for moving solar reflecting means are also disclosed.

  • Patent number: 4023500
    Abstract: A high-speed ground transportation system wherein a vehicle rides on a film of air and is propelled as a free piston through a tunnel by pneumatic pressure. Seals on the vehicle create fluid communication between a high pressure area behind the vehicle and the area beneath the vehicle while preventing fluid communication between that high pressure area and an evacuated area located in front of the vehicle, to create an air film beneath the vehicle upon which it rides. Cargo handling means are located near the tunnel and shunting means enable the vehicle to be shunted into those cargo handling areas when desired. Booster stations located at selected points serve to increase a pressure differential across a vehicle to assist that vehicle when necessary, and magnetic means are used to maintain the vehicle in a upright orientation as it is propelled through a tunnel.

  • Patent number: 4013382
    Abstract: An apparatus for converting water wave movement into power. A float is located in a body of water, and the apparatus converts the up and down movement of that float caused by waves in the water to operate a pump to displace hydraulic fluid through a hydraulic pumping station which actuates fluid motors, or the like to produce power. The force of the float movement is multiplied by a mechanical advantage so that the pump displaces the hydraulic fluid on both the upward and downward movement of the float even in calm water. A plurality of modules are interconnected to take advantage of as much of a wave front as desired.
