  • Publication number: 20240076688
    Abstract: Compositions and methods for controlling pests are provided. The methods involve transforming organisms with a nucleic acid sequence encoding an insecticidal protein. In particular, the nucleic acid sequences are useful for preparing plants and microorganisms that possess insecticidal activity. Thus, transformed bacteria, plants, plant cells, plant tissues and seeds are provided. Compositions are insecticidal nucleic acids and proteins of bacterial species. The sequences find use in the construction of expression vectors for subsequent transformation into organisms of interest including plants, as probes for the isolation of other homologous (or partially homologous) genes. The pesticidal proteins find use in controlling, inhibiting growth or killing Lepidopteran, Coleopteran, Dipteran, fungal, Hemipteran and nematode pest populations and for producing compositions with insecticidal activity.

  • Patent number: 6867310
    Abstract: The present invention provides transition-metal-catalyst-based methods for the arylation and vinylation of activated methyl, methylene, and methine carbons with aryl halides, vinyl halides, and the like. The methods of the invention provide several improvements over existing methods, including the ability to synthesize efficiently and under mild conditions ?-aryl and ?-vinyl products from a wide range of starting materials, including ketones, esters, hydrazones, and imines. Furthermore, the methods of the invention may be used in an asymmetric sense, i.e. to produce enantiomerically-enriched chiral ?-aryl and ?-vinyl products.

  • Patent number: 6772449
    Abstract: A toilet seat ventilation assembly for mounting on a toilet bowl includes a seat having a and air passageway and plurality of vent holes formed in the seat. A tubular manifold is rotatably secured in mounting fixtures at the rear of the toilet seat. The toilet seat is rotatably secured to the manifold by hinges having a passageway for communicating air from the toilet seat to the inlet of the manifold. The mounting fixtures have a passageway for communicating air from the outlet of the manifold to an exhaust conduit. The toilet seat cover has hinges for connecting the toilet seat cover to the manifold in a fixed manner. Pivoting the toilet cover between a horizontal position and a vertical position causes the manifold to rotate within the toilet seat hinges and the mounting fixtures.

  • Patent number: 6766747
    Abstract: A game table includes a storage area with a center leaf horizontally mounted in the storage area. When the top cover is in a closed position, the center leaf is positioned at the bottom of the storage area. A pulley system is used to raise the center leaf into a playing position when the top cover is moved to the open position. When the top cover is closed again, the pulley system lowers the center leaf into the storage area. A game board and game pieces positioned on the center leaf are maintained in the same position when the top cover is closed and the center leaf is lowered into the storage area. By maintaining the center leaf in a horizontal position, persons playing a game can suspend the game and safely keep the game pieces in the same position by merely closing the top cover. The game may be resumed by opening the top cover to raise the center leaf back into the playing position.

  • Patent number: 6323366
    Abstract: The present invention provides a method for the preparation of a wide range of primary arylamines. The arylamines are prepared in two efficient, straightforward transformations: 1) an activated aryl group and an imine group are combined, in the presence of a transition metal catalyst, under conditions wherein the transition metal catalyst catalyzes the formation of a carbon-nitrogen bond between the activated carbon of the arene and the imine nitrogen; and 2) the resulting N-aryl imine is transformed, via any of a number of standard protocols, to the primary arylamine. The method of the invention may also be exploited in the preparation of vinylamines.
