Abstract: Liquid samples of like composition and like or unlike volume are collected simultaneously. Liquid is withdrawn continuously from a body of liquid to be sampled. The withdrawn liquid is passed continuously into and fills a confining region having multiple outlets. Streams of liquid from the respective outlets are diverted intermittently for sample collection and otherwise are returned to the source body of liquid or to waste. The multiple-outlet confining region is embodied in a plenum chamber, and individual diverter chambers are provided for the streams of liquid from the plenum chamber, together with means for effecting the diversion.

Abstract: Liquid samples are collected simultaneously by intermittent diversion of a stream withdrawn from a body of liquid to be sampled and passed by a diversion locus into a splitting region having multiple outlets. The liquid is prevented from flowing through the outlets during periods of diversion, and upon completion of such period the outlets are opened to pass liquid streams therefrom. This multipleoutlet confining region is embodied in the sample compartment of a diverter chamber, and the valving includes a horizontally movable slide adapted to close off and to open up all the outlets in unison.

Abstract: Conveyor apparatus for temporary holdup of textile strands, especially crimped strands for setting. Screenlike conveyor belts receive the strand between downwardly converging flights and discharge the strand from between upwardly diverging flights. The conveyor apparatus is housed in a heated steam-fed enclosure.

Abstract: Surface wetting of scored textile film strands facilitates fibrillation thereof. Liquid water of inert aqueous solution is applied by various means in the form of droplets or a thin surface layer to such strands, which then are compressed laterally and longitudinally to fibrillate and crimp them, as by stuffer crimping, in a continuous process optionally including predrawing the strands to increased length.

Abstract: Successive samples are taken periodically from a body of liquid with the aid of pressurized fluid serving as both timing medium and sample propellant. Alternative high-pressure and low-pressure paths for the fluid correspond to high-lift and low-lift uses in sampling apparatus adjustable as to interval between successive samples and duration of taking of each sample, as well as convertible between levels of sample lift.
