Abstract: A reusable closure for placement within the neck of a returnable and reusable container for liquid includes an improved sealing device for preventing contamination of the container. The sealing device achieves a tight seal between a ball and a valve seat within the closure. A cap abutment or spring may optionally be provided to further enhance the tightness of the seal.
Abstract: Agriculturally acceptable pesticidally active ingredients, such as herbicides, fungicides, and insecticides of low melting point, typically in the range from about 30.degree. C. to about 130.degree. C. and preferably in the range from about 30.degree. C. to about 90.degree. C. and low water solubility, typically in the range from about 0.01 ppm to about 1000 ppm and preferably in the range from about 0.01 ppm to about 300 ppm are frequently formulated as water-dispersed agrichemically acceptable formulations such as wettable powders (WP), water-dispersible granules (WG), and suspension concentrates (SC) and the like.

Abstract: A combination respiratory filter and sampling device has been developed which collects airborne contaminants for respiratory exposure measurements. The devices, which fit existing commercial half-mask respirators, are generally smaller and lighter in weight than existing filters, and have low resistance to airflow, so they can be comfortably worn by people performing their normal work duties. Each device consists of at least a front, a middle and a back section which can be independently separated and analyzed by traditional laboratory techniques. The filtering and sampling media thicknesses and types can be adapted to target specific compounds.
