  • Publication number: 20050166284
    Abstract: Compositions and methods for protecting a plant from an insect pest are provided. In particular, nucleic acid sequences encoding insect protoxins modified to comprise at least one proteolytic activation site that is sensitive to a plant protease or an insect gut protease are provided. Cleavage of the modified protoxin at the proteolytic activation site by a protease produces an active insect toxin. Methods of using the modified insect protoxin nucleic acid sequences and the polypeptides they encode to protect a plant from an insect pest are provided. Particular embodiments of the invention further provide modified insect protoxin compositions and formulations, expression cassettes, and transformed plants, plant cells, and seeds.

  • Patent number: 6733623
    Abstract: An apparatus and a method for adhering a flexible film to a ventilated platen without air entrapment problems are described. In the apparatus, a tool body and a tool lid are connected together by a hinge means in a clam-shell configuration. The tool body has a cavity formed such that a ventilated platen can be tightly positioned therein with a top surface of the platen exposed. A flexible film is mounted to an inner surface of the tool lid facing the tool body and pushed down onto the ventilated platen while air is being withdrawn from the ventilated platen. The adhesion process for the flexible film to the platen can be completed without any air entrapment problem existing between the film and the platen.

  • Patent number: 6330982
    Abstract: This invention relates to a hammer mill used for feed processing, food processing or chemical industries. The said hammer mill has a casing, a rotor arranged in the casing and is provided with several hammers, and a vibrating screen with an active power source located around the rotor. The vibrating parameters can be set for control. In the cross section of the rotor, the width of the screen in the horizontal direction is more than that in the vertical height and it is symmetrical at the left and the right.
