Abstract: A mixing device for use in a duct (12), particularly for use when testing the efficiency of a filter (10) in the duct by aerosol injection, consists of a pipe (24) with a closed end arranged near the middle of the duct (12). The other end of the pipe is connected to a source (26) of compressed air. Near the closed end are one or more narrow holes (28) so that narrow air jets are created across the width of the duct. The air jets create large-scale turbulence in air flowing in the duct, even where that air flow was already turbulent, such that thorough mixing is achieved within as little as two duct diameters or less, while producing negligible pressure drop. The mixing device may be combined with an aerosol injector (20, 22).

Abstract: A twist-on or wire-nut electrical connector (10) having a rigid, electrically insulative upper body (12), a flexible, elastic, electrically insulative lower skirt (14), and a coil spring (22) within the body for gripping wires (30) which may be inserted therein. The provision of a flexible, elastic skirt (14) allows the insertion of a larger number of wires (or larger sized wires) into the connector; the skirt (14) further deforms to fit more easily within a crowded junction box or other high-density wiring environment. Unlike prior art twist-on connectors, the lower skirt (14) is attached directly to the open end of the polymeric body (12), allowing greater application of torque to the rigid body. In the preferred embodiment, the upper body (12) is formed of polypropylene, the lower skirt (14) is formed of a styrene-butylene compound or an olefinic thermoplastic vulcanizate, and the connector is constructed by multicomponent injection molding.

Abstract: A method and apparatus for minimizing the environmental release of acids and toxic organic compounds from a waste incinerator-air pollution control train. The apparatus comprises an incinerator (1), a gas cooling means such as a waste heat boiler (7) or quench chamber, a means for the partial removal of acid gases and dioxins by contact with either finely-divided alkaline solids or alternatively, by an alkaline solution in a spray drier-absorber, a dry solids collection means such as a fabric filter or electrostatic precipitator, a wet scrubber means (22) for residual metal, dioxin/acid gas removal and an induced draft fan. In the method of this invention, the final wet scrubber stage operates without alkaline neutralization, but under scrubber acid concentrations and operating conditions that provide an exhaust gas within compliance limits of emission regulations. The contaminated liquor blowdown from the wet scrubber, which contains toxic organics and acids, is recycled back into the incinerator. The aqueous acid liquor blown down to the incineration is vaporized therein, most of the toxic organic content of the liquid is destroyed by the re-incineration, and the regenerated acid gases are largely removed by the first dry scrubbing stage.
