  • Patent number: 7385301
    Abstract: A wave energy conversion system converts wave energy within a wave medium into electrical energy. The wave energy conversion system includes a base substantially connected to a wave-medium floor, a tidal platform connected to the base and a tidal float connected to the tidal platform. An axle is connected to the tidal platform with an inductive coil positioned within the axle, such that an axis of the inductive coil is parallel to the axle. A magnetic sleeve includes a magnetic sleeve opening, such that the axle passes through the magnetic sleeve opening. A float member is connected to the magnetic sleeve. A wave moving through the wave causes displacement of the float member, causing the magnetic sleeve to move relative to the inductive coil and generate electrical energy within the inductive coil.

  • Patent number: 6688971
    Abstract: A chopper arrangement for a harvesting machine comprises a body that is rotated in a predominantly vertical axis of rotation. The body is provided with a plurality of radially extending knives that are axially distributed along the body. The knives have radially outer ends that are arranged in a conical shape. In this way the knives at the first end having a smallest radial extension are rotated at a slower circumferential speed than knives having a larger radial extension.

  • Publication number: 20020028703
    Abstract: The present invention relates to a feeding device of an agricultural vehicle having a first auger, arranged on the floor of a collecting device for harvested crop. A second auger receives the harvested crop from the first auger. The second auger extends, at least across a portion of its length, at an angle to the longitudinal direction of the first auger. A flexible continuous feeding spiral extends through the first and second augers. The feeding spiral (44) is preferably flexible and coreless.

  • Patent number: 6070816
    Abstract: A straw chopper arrangement for an agricultural combine wherein the chopper is provided two vertically arranged rotors. The rotors are provided with a number of circumferentially spaced radially extending impeller blades. The outer ends of the impeller blades are provided with pivotally mounted flails. The flails are vertically spaced from one another. The straw chopper arrangement is also provided with a chopper housing for receiving the rotors. The housing having at least two walls that are provided with inwardly extending shear bars which are located in the vertical space defined by vertically adjacent flails.

  • Patent number: 5019014
    Abstract: A harvesting machine is provided with a foreign material protective device to extract stones, sand and other material from the harvesting goods which are gathered by the header. With the present invention, the protective device is provided with a housing defined by two longitudinal walls, perpendicular to the flow of crop material, and two side walls, parallel to the flow of crop material. The longitudinal walls of the housing diverge slightly towards the outlet opening of the housing. The outlet opening is closed by a door having an impeller which extends into the housing when the door is closed. The impeller ejects material from the housing through the outlet opening when the door is opened.

  • Patent number: 4211057
    Abstract: An automatic table height control for a combine harvester including a height sensing assembly and a control system. The height sensing assembly includes a finger support shaft rotatably journaled on the bottom of the table. A spring is provided to rotate the shaft in one direction. A plurality of ground engaging fingers are pivotally connected to the finger support shaft. A lost motion connection is provided to limit rotation of the finger support shaft relative to each finger. An iron vane is attached to one end of the finger support shaft. A pair of proximity switches are mounted on the crop harvesting table adjacent the path of movement of the iron vane. When the vane is close to both proximity switches, they are open. When one of the ground engaging fingers rotates the iron vane away from one proximity switch that switch closes and energizes a relay in the control system that energizes a solenoid on the header height control valve to raise or lower the table.
