Abstract: An apparatus for removing dust from a fiber sample for subsequent analysis is disclosed. A first upper cylindrical chamber containing a fiber sample has a tangential air jet and a radial air jet installed to swirl and tumble the fiber sample in a cyclonic fashion, thus liberating the dust from the sample when either a positive or a negative pressure is applied through the air jets. The liberated dust particles are then screened out through a 100 mesh screen filter and exhausted through a funnel. The device can be equipped with a second stage chamber containing a plurality of step-stage filters and a third stage plurality of microfilters to selectively screen the dust particles. A blow bottle containing an aqueous medium to absorb even the finest dust particles or gas can also be added as a fourth stage.

A soft woven nylon rope wick is used to convey chemical solution from a reservoir by means of capillary action. The rope apparatus, which is physically supported, is leveled and positioned to selectively contact certain plants as the wick is moved across an agricultural field. Thus chemical solution is deposited selectively only on contact with the wick.

Abstract: The undesirable coloration generally found in cottonseed and other oilseed protein isolates prepared from oilseed flours or concentrates is substantially eliminated or improved by treatment of the flours with a specific solvent mixture containing a non-polar solvent, a polar solvent, a quantity of water, and a small quantity of a food-grade organic acid. The improved isolates render the consumer product more acceptable from the point of view of improved coloration.
