Abstract: An apparatus for sampling a gas stream and concentrating selected constituents found therein. The apparatus includes a collection chamber into which a gas stream is drawn and a nozzle which sprays charged droplets of a collection fluid countercurrent to the gas stream. The charged droplets, now containing the selected constituents, are propelled to the wall under the influence of an electrostatic force and collected in a collection well at the bottom of the collection chamber. The apparatus can include a cyclonic flow inducer which imparts a circumferential component to the gas stream velocity, thereby enhancing collection efficiency by increasing the residency time of the gas stream within the collection chamber.

Abstract: A carrying case for wire and cable that includes a removable top and bottom with sides, front and back hinged at three junctions and latched at the forth. The case opens to form a linear sheet exposing six wire supporting hooks. In the closed condition two groups of three hooks are end abutting and top wall abutting thereby preventing the cable from leaving the hook in the event the case is tumbled about.
