  • Patent number: 6527059
    Abstract: The apparatus for tilling soil provides a significant reduction in energy consumption. The apparatus includes one or more sweeps which are effective for subtilling the soil as it is moved therethrough. One or more tillers are provided ahead of the sweeps, sufficiently near the path of travel of the outermost ends or tips of the sweep blades so as to disturb or loosen the soil directly in the path of the ends of the blades. By positioning the tillers relative to the sweep tips in this manner, energy consumption may be significantly reduced in comparison to subtilling devices having coulters or other tillers positioned ahead of the center of the sweeps.

  • Patent number: 6502531
    Abstract: An apparatus is provided for restraining wildlife with minimal trauma to the animal. The apparatus includes a housing having open front and rear ends allowing the entry and exit of a target animal, while the rear end includes an openable/closable door effective for controlling the egress of the target animal from the housing. To immobilize the animal, a deer lift is disposed within the interior of the housing having opposed, outwardly and upwardly inclined surfaces which are vertically movable between a first, lower position and a second, raised position. The opposed surfaces are spaced from one another with the space therebetween defining a narrow passageway allowing the target animal to walk between the opposed surfaces in the lower position. However, the width between the opposed surfaces is sufficiently close such that they engage the trunk or body of the animal when raised.

  • Patent number: 6503698
    Abstract: A method for the cryopreservation of zona pellucida-intact, early-stage swine embryos, morulae and blastocysts includes centrifuging the embryos prior to cryopreservation in order to remove intracytoplasmic lipids. The lipids are localized external to the embryo proper inside the zona pellucida, thus neutralizing harmful effects which prevent subsequent embryological development. The embryos may be cryopreserved by vitrification or conventional freezing. After recovery and rehydration, zona pellucidae are removed, and intact, viable embryos are transferred to recipient females.

  • Patent number: 6490917
    Abstract: A magnetostrictive precipitation gage includes a catch tube having an upper opening configured to receive precipitation therein. A vertical magnetostrictive rod and corresponding magnetic float linearly displaceable thereon are used to determine the fluid level within the catch tube. More particularly, as the fluid level fluctuates in the catch tube, so will the vertical position of the float, which interacts magnetically with the magnetostrictive rod. Accordingly, the vertical position of the float may be detected to determine the fluid level within the catch tube, and calculations regarding precipitation may be performed.

  • Patent number: 6493363
    Abstract: A system for automated monitoring of pest insects having sensor units which include an insect electrocutor trap modified by the inclusion of electronic circuitry to sense, count and store the numbers of insects killed by it. The numbers of insects can be displayed at the electrocutor and/or transmitted to a remote computer that can acquire and time-stamp counts from thousands of distributed electrocutors for subsequent analysis and display. The data from the units is transmitted through a communications system which is organized into a two or more levels of multiplexing modules. Each multiplexing module has a plurality of inputs from next level multiplexing modules, with the exception of the last level multiplexing modules. The last level multiplexing modules have a plurality of inputs from sensor modules outputting data.
