    摘要： A fish diversion apparatus for a water intake of a dam includes a frame extending between a top end oriented towards the water surface and a bottom end oriented below the water surface. The frame supports a number of bar screen panels below the water surface. The bar screen panels allow water flow therethrough from an upstream side to a downstream side. A flow scoop extends from the bottom end of the frame to direct the fish along the upstream face of the bar screen panels. A fish diverter device is provided adjacent the top end of the frame in communication with the upstream side of the bar screen panels.

    摘要： An apparatus and method are provided for tracking the position in three dimensions of one or more objects underwater. Two multibeam sonar heads are positioned to operate in intersecting planes. The two multibeam sonar heads are synchronized to the time signals are emitted from a transmitter. The echoes of the emitted signals are detected by both heads and the data from the two sonar heads is transmitted to a computer that processes the data and can display the position of the one or more objects.

    摘要： The amount of vapor of a halogenated phenol released by wood treated with the halogenated phenol is reduced by contacting the treated wood with an organic compound having cationic groups capable of forming a water-insoluble halogenated phenoxide salt. For example, contacting pentachlorophenol treated wood with a quaternary ammonium such as didecyldimethylammonium chloride significantly reduces the release of pentachlorophenol vapors from the wood.

    摘要： A protective optical filter assembly for thin film filters having two transparent substrates facing one another and separated by a resilient element, a sealed region is formed between the transparent substrates by applying a compressive force that compresses the resilient element. The thin film filter may be contained within a carrier. The compressive force may be generated by one or more interference-fit aperture rings or threaded apertures ring, a given aperture ring may be opposed by another such aperture ring or a fixed stop. Alternatively a snap fit carrier may be used to generate the compressive force. The sealed region may have a gas having a positive pressure or a liquid.

    摘要： A generally cylindrical shaped tool handle holds multiple sizes of tools. The handle includes one or more holding slots each positioned on one of multiple outer surface faces into which tools are inserted and held. Each holding slot includes one or more contoured compartments in which tools rest when engaged with the handle. Each contoured compartment is of a size and dimension which corresponds to one or more tool sizes. In the preferred embodiment of the tool handle, three of its outer surface faces have a continuous holding slot with multiple receiving holes for inserting therein hexagonal wrenches of multiple sizes. The continuous holding slots of the preferred embodiment of the handle include multiple contoured compartments for holding an inserted hexagonal wrench. Each contoured compartment is formed about a corresponding receiving hole. A lock is positioned over the contoured compartment to irremovably confine the short leg of the hexagonal wrench within the contoured compartment. Hexagonal shaped tools other than wrenches may be used with the handle of the present invention such as screwdrivers and socket wrenches. A tool holder of the present invention is designed to slide over the handle and to hold multiple sizes of tools which may be used with the handle. The tool holder includes a tool holding member having a plurality of cavities for inserting therein appropriately sized tools and a tool handle holding member having a cavity with an inner hollow shape corresponding to a shape of the handle.
