  • Transgenic plants and methods for production thereof
    Patent number: 6753459
    Abstract: Genetic constructs, transformation vectors and methods are taught for production of transgenic plants which can be selectively removed from a growing site by application of a chemical agent or physiological stress. The invention links a target gene for the trait of commercial interest to a conditionally lethal gene, which can be selectively expressed to cause plant death. By use of the genetic constructs, transformation vectors and methods of the present invention, invasion of environments and contamination of commercial non-engineered productions by transgenic plants can be avoided. Methods are also taught for transformation of Brassica species.
    Type: Grant
    Filed: June 22, 2001
    Date of Patent: June 22, 2004

  • Piston positioning indicator
    Patent number: 4140045
    Abstract: In a piston actuated valve, means for determining the position of the operating piston by means of at least one insulated contact probe which is inserted through the wall of the cylinder. Two or more can be used, one in each extreme position of the piston. As the piston moves into its extreme position, contact is made with the probe and a suitable signal is sent, indicating that the piston is in that extreme position.
