Patents by Inventor Richard G. Koegel

Richard G. Koegel has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6248938
    Abstract: A value-added composition of matter containing plant matter from transgenic alfalfa which expresses exogenous phytase activity is disclosed. The phytase activity is a gene product of an exogenous gene encoding for phytase which has been stably incorporated into the genome of alfalfa plants. The transgenic alfalfa expresses phytase activity in nutritionally-significant amounts, thereby enabling its use in animal feeds to eliminate the need for phosphorous supplementation of livestock, poultry, and fish feed rations.
    Type: Grant

  • Patent number: 6101797
    Abstract: Method for processing plant material in which a first rotatable crushing roller with an outer generally cylindrical surface cooperates with a second adjacent rotatable crushing roller also having an outer generally cylindrical surface. The rollers, mounted with their surfaces positioned in close proximity to each other, rotate in opposite directions to receive and crush plant material. A rotatable impact rotor having a plurality of outwardly extending projections is mounted rearwardly of the crushing rollers for impacting plant material that has passed between the rollers to macerate the plant material that has been previously crushed by the rollers. The crushed and macerated plant material is diverted and again impacted one or more times by the outwardly extending projections of the impact rotor.

  • Patent number: 5824779
    Abstract: A value-added composition of matter isolated from the juice of a transgenic green plant is disclosed. The composition of matter includes enzymatically-active phytase, xanthophylls, and dietary protein. The phytase is a gene product of an exogenous gene encoding for phytase which has been stably incorporated into the genome of the transgenic green plant, while the xanthophylls and the dietary protein are components native to the juice of the transgenic green plant.

  • Patent number: 5152127
    Abstract: An apparatus and method for the treatment of forage material and other agricultural plants by crushing and impact maceration. The apparatus includes a pair of rotatable, generally cylindrical crushing rollers and a rotatable impact rotor having outwardly extending projections such as fins. Forage material is first passed between the crushing rollers where force applied to the rollers flattens the tubular structure of the plant stem, splitting or creating longitudinal cracks and making the plant fiber more compliant and ribbon-like. Additional maceration occurs as the crushed material is next impacted by the impact rotor, resulting in further splitting and separation of the stems into ribbons. The resultant macerated forage material produced may be subsequently pressed into mats for accelerated field drying. The mats could then be harvested by either baling or chopping when the desired moisture content is achieved.
