  • Patent number: 7521816
    Abstract: A water powered motor for extracting raw energy from a water current and converting it to kinetic energy. The water powered motor is generally rectangular in shape with a generally round water wheel consisting of foldable vanes. The vanes receive raw energy produced by water current transforming that raw energy into usable energy for powering a pump, electric generator or as a general power source to power other equipment such as desalinization machinery.
    Type: Grant

  • Patent number: 5779541
    Abstract: A combine yield monitor replacing a portion of a conventional cross-auger moving grain through a combine. The monitor having a housing which has an opening through a bottom wall of the housing. The yield monitor further including an auger, rotatably mounted within the housing, having a screw blade and connected to the cross-auger to replace a portion of the cross-auger. The auger having a portion of the screw blade removed intermediate the ends to form an accumulation volume for momentarily stopping grain flow through the auger. The auger further having a portion of the screw blade positioned over the opening to move grain away from over the opening. A load cell located below the opening for measuring the weight of the accumulation volume of grain in the auger.
