Abstract: A butterfly valve for a conduit defining a passage for a flow of a fluid therethrough in a flow direction. The butterfly valve includes a shaft rotatably mounted to the conduit and defining a longitudinal axis along its length. The butterfly valve includes a valve body coupled to the shaft, such that the valve body is rotatable along with the shaft about the longitudinal axis between a closed position and a fully open position. The valve body includes a first major surface, a second major surface opposite to the first major surface, a perimeter surface, a central plane, a first lobe, a second lobe, and a third lobe.

Abstract: A system, composition and method of treating a body of water with an active in a tablet form or contained in a water soluble container to improve overall water quality and ensure adequate dispersion of the active. The composition preferably comprises active(s) and an effervescent couple in solid form. The method preferably comprises dispensing a treatment composition by dropping or throwing the pellets or water soluble containers into the water. The water soluble containers preferably are bag-within-a-bag containers, with an inner bag and outer bag each having the treatment composition and air. Upon contact with the water, the effervescent couple will react to form carbon dioxide, which aids in dispersing the active and any optional ingredients in the treatment composition throughout the water.

Abstract: A bait station for attracting and killing insects with a nithiazine-type insecticide is constructed in a substantially flat configuration, with the insecticide formulated as a solid coating on the surface of a solid sheet of moisture-free nonabsorptive material, the station further containing one or more ampoules of an attractant composition. The coated sheet and ampoules are held in a housing, with the ampoules in a compressible portion of the housing permitting them to be manually broken to discharge their contents on command, the housing containing appropriately positioned openings to both expose the insecticide surface and to permit release of the attractant vapors.

Abstract: The invention relates to novel compositions and methods for controlling cockroach populations using the (S)-(+) enantiomer of hydroprene.
