Abstract: Denim articles of clothing such as blue jeans, are conventionally treated with a permanganate. The permanganate is thereafter neutralized with a liquid composition containing peroxide, a sulfate and deionized water. The composition neutralized the permanganate, prevents the yellowing of the article and reduces the biological oxygen demand in plant effluent.

Abstract: Stress cracking in poly(alkylene terephthalate) or polycarbonate articles of manufacture is inhibited by applying to the article a hydrophilic-substituted aromatic hydrocarbon having either an alkyl or aryl side chain, such as, e.g., a sodium sulfonate. Preferably, the stress crack inhibitor is applied to the article in the form of a dilute aqueous caustic bottle washing solution.

Abstract: A method is designed to treat the effluent from a commercial laundry facility. Commercial laundry facilities produce typically a relatively clean effluent produced by washing clothing, towels and the like. The same laundry facility can also produce an oily effluent from washing shop towels, mops and the like. The effluent produced by the commercial laundry is all subjected to a particulate filtration and heat exchanger. The nonoily effluent is then directed to the sanitary drain. The oily effluent is treated with a demulsifier to break down the oil/water emulsion and is subsequently transferred to a oil/water separator. This permits the capacity of the oil/water separator to be approximately 1/3 to 1/4 of that which would be required to treat all effluent in the laundry.

Abstract: A paint detackification treatment for paint spray booths include a water soluble polymer which is a dicyanadiamide formaldehyde condensation product in combination with multivalent metal salt, preferably aluminum chlorohydrate. The composition is added to the overspray collection tanks and acts to detackify particles of paint which are collected in a water curtain. The combination of the dicyanadiamide formaldehyde and aluminum chlorohydrate permits a lower concentration of polymer to be used and also permits this detackification product to be used with a wide variety of aqueous and oil based paints.

Abstract: An apparatus for dispensing solid or semi-solid detergents includes a hollow elongated opening or chute and an arcuate plate that extends from the side wall of the apparatus to beneath the chute. This plate provides a planar support for a detergent bar placed within the chute. Water is sprayed down the arcuate plate and projects against the detergent supported on the planar support causing it to dissolve and flow down a drain. The chute has a unique geometric design which is suitable to receive only one uniquely shaped elongated detergent bar. In a kitchen having several detergent dispensers, each detergent dispenser will have a uniquely defined chute so that only the appropriate detergent can be used in the appropriate dispenser.

Abstract: Method and apparatus for dispensing detergent from within a container comprises directing a water spray transversely of the container vertical orientation to dissolve and remove detergent in solution from the container. The transverse direction of water spray greatly improves detergent dispensing performance and minimize clogging of the system during down times.

Abstract: A final rinse for a phosphatized metal surface includes a phosphoric acid solution including aluminum chlorohydrate. The aluminum chlorohydrate solution is applied at a concentration of about 100 to about 1500 ppm at a pH of 3 to about 4.5. The pH is obtained by controlling the concentration of the phosphoric acid. This is preferably used to coat previously phosphatized metal surfaces such as iron, steel, aluminum and galvanize.

Abstract: An inert water soluble dye is added to a concentrated water treatment composition. This mixture is added to the water in a circulating water system such as a cooling tower. The concentration of the dye and the concentration of the actives in the treatment composition are proportionate to each other. The concentration of the treatment composition in the water system can be determined by measuring the percentage of light absorbed by the dye in the water. This can be determined by use of a colorimeter. Fluorescein is the preferred dye.

Abstract: A container and method for changing liquid cleaning compounds into a dispensing apparatus employs a blow molded plastic container that includes a filling inlet and a discharge outlet. The discharge outlet is a fitting adapted to snap onto a quick connect coupling and includes a tube that extends to the bottom of the container. The tube is inserted into the container while it is still hot. As the container cools, it shrinks forming a tight seal around the tube. The coupling snaps onto the outlet and sealingly engages it. The opposite end of the coupling is attached to the dispenser which acts to evacuate the cleaning compound from the container. Upon depletion of the cleaning compound within the container, the coupling is separated from the container. Since the coupling includes a one-way valve, cleaning compound within the tube is not released. This provides a closed system for dispensing cleaning compounds deterring misuse.

Abstract: This new detergent delivery system involves the formation of a detergent solution from a solid detergent material.

Abstract: A liquid chemical delivery system automatically delivers viscous chemicals to a number of destinations, such as a number of industrial clothes washers. Several distinct chemicals are pumped, one at a time, into a manifold. The chemical being pumped is mixed with water in the manifold and then transported through a distribution line to its specified destination. By mixing the chemicals with water, viscous chemicals are diluted and delivered using a low pressure delivery system. A single flow meter is used to calibrate all the chemical metering pumps and to recalibrate those pumps periodically, thereby providing accurate chemical metering. The manifold and distribution tube are automatically flushed with water after every chemical delivery so as to reduce corrosion and maintenance costs. In addition, potentially reactive chemicals are kept separate from one another despite the use of only a single distribution line.
