  • Agricultural product microscreen method and apparatus
    Patent number: 6150158
    Abstract: Methods and apparati for screening compounds for agricultural activity has now been developed which employ e.g., intact plants grown in microtiter plates on very small amounts of plant growth media containing a test compound. In comparison to the standard greenhouse screen, the microscreen requires vastly less space, labor, and test compound. However, unlike in vitro screens, responses of intact plants are assayed. Using the microscreen, high-throughput screening of test compounds can be accomplished using whole plant responses as the assay.

  • Apparatus and process for pneumatic segmenting of compacted fiber wads for continuous package layer formation
    Patent number: 4991261
    Abstract: A layered yarn package is formed of continuous filament yarn wads wherein the yarn alternates between compacted and extended lengths by axially compacting the yarn into a length, segmenting the length into alternating extended and compacted lengths, then arranging the compacted lengths in a common axial direction one next to the other to form a layer. The segmenting is accomplished by jetting pressurized fluid onto the continuous filament yarn wads in a programmed manner.
