    Abstract: The disclosed diaryl urethanes are made by capping poly(oxyalkylene) diols with monoisocyanates. These diurethanes are characterized by a desirable hydrophobe/hydrophile balance typically evidenced by low cloud points, the ability to form micelles in aqueous media, the ability to reduce stable foam, and the ability to be taken up and retained by paper fibers, thereby imparting increased hydrophilic character to paper sheets made from the fiber. The low foaming or de-foaming capability of these compounds is particularly useful in paper re-wet compositions and machine dishwashing detergents and additives. The hydrophobe/hydrophile balance is typically obtained through a combination of oxyethylene and oxypropylene units or blocks in the oxyalkylene chain.

    Abstract: A cleaning method and system for meat smokehouses and similar meat processing facilities including a plurality of atomizing spray nozzles positioned within the smokehouse and the duct work therein. While air and steam are circulated within the smokehouse, a cleanser solution is introduced into the facility through the atomizing spray nozzles. The atomized cleansing solution provides a saturated atmosphere of cleanser which is carried to all surfaces of the smokehouse by the circulating air. After completion of the wash operation, pure water and/or a weakly acid aqueous solution is introduced into the smokehouse through the nozzle system to effect rinsing of the smokehouse.

    Abstract: Fabrics are treated in machine drying apparatus to reduce static electricity carried by the fabrics, soften the fabrics and improve other fabric properties. A sponge impregnated with a heat softenable solid or semi-solid fabric-conditioning agent is placed within the dryer drum and the fabrics are tumbled in the dryer thereby causing some of the fabric-conditioning agent to be transferred to the fabric. When the dryer is heated, the heat of the dryer helps the fabric-conditioning agent to soften and assists in its distribution over the surface of fabric with which the impregnated sponge is brought into tumbling contact.

    Abstract: A continuous on-stream milk standardizing and blending system. Whole milk having a known fat content is introduced into a centrifugal separator for separating the milk into its skim and cream components; the milk entering the separator through a conduit having a flow meter positioned therein for providing a digital output signal corresponding to the flow rate therethrough. A digital control unit compares the input signal from the milk flow meter with an input signal received from a similar flow meter positioned in the cream conduit downstream from an air-operated throttling valve; the control unit providing a control signal which regulates the setting of the throttling valve. This setting controls the flow rate of cream through the cream conduit and, thus, establishes the fat test of the cream based on the known fat test of the whole milk. A portion of the cream is then recombined with the skim component in an amount controlled by the digital control unit so as to provide a standardized milk product of the desired fat content (e.g. 3.5% milk). Various additional additives (e.g. condensed skim milk) can also be blended with the standardized milk product.
