Abstract: A method and system are described to remove solvent vapors emanating from a source in a work place. The air stream is passed through a fogging chamber in which a plurality of ultrasonic foggers are used to create a supersaturated condition in the form of vapor and droplets of a scrubbing liquid such as water. The supersaturated condition is accompanied with a large amount of turbulence and mixing flows throughout the chamber to reduce the ability of solvent vapors from bypassing contact with the scrubbing liquid. The scrubbing liquid droplets and vapor are then condensed out in a cooling condenser and collected to leave a scrubbed air stream from which a substantial amount of the solvent vapors is removed. The scrubbed cooled air stream may then be recirculated for reuse in the work place. Several embodiments are shown and described including a scrubbing system in which several fogging chambers and condensers are used in tandem for an enhanced removal of solvent vapor from the air stream.

Abstract: A device is described to enable the direct hygienic collection of a urine sample in a specimen tube. The collection aid is formed with a hollow body. A main opening of the hollow body is oriented to receive a female or male voiding stream which is confined in a chamber having specimen and excess urine outlet ports. The specimen outlet is shaped to releasably retain a specimen container such as a centrifuge tube while the excess urine outlet is effectively sized and selectively spaced from the specimen outlet to assure sufficient flow through the specimen outlet for a sample while enabling the remainder to be drained away. In one embodiment the hollow body is formed of relatively rotatable segments shaped to enable the hollow body to be adapted to be used for both male or females. Several embodiments are described.
