Abstract: Improved separation of emulsified hydrophobic organic soils can be obtained from aqueous effluents using an amphoteric dicarboxylate surfactant material in combination with cationic destabilizer or flocculent materials. Such a treatment in combination with an acidic pH adjustment causes the rapid separation of hydrophobic organic soils from the aqueous stream. The treated aqueous stream is environmentally compatible.Improved laundry detergents comprising an organic amphoteric carboxylate surfactant and selected nonionic surfactants provide both cleaning for fiber and fabric containing items soiled with substantial quantities of hydrophobic soil. The pH of an effluent generated in such cleaning processes can be adjusted to an acid pH and treated with a cationic material causing a break that permits rapid and substantially complete separation of the hydrophobic organic soils from the effluent. Residual concentrations of organic soil in effluent water can be less than 250 ppm and can be as low as 10 ppm.

Abstract: An insect trap using attractant light, comprising a source of light and a housing can be mounted on a vertical surface or placed near a ceiling surface. The housing and the source of light cooperate to form an upwardly facing opening for the facilitated entry of flying insect pests and for the reflection of light onto the vertical surface. Insects that enter the trap are immobilized on a surface within the trap. Cooperation between direct radiant light, reflected light and an upwardly facing entrance for insects substantially increase capture rates.

Abstract: Disclosed is a dispenser 10 for a solid chemical 13 and a method of dispensing the chemical 13. Water enters via an inlet line 22 and is sprayed from a spray nozzle 21, so that the solid chemical 13 is dispensed in the form of an aqueous chemical solution via outlet line 17. The solution's concentration is adjustable by varying the distance between the spray nozzle 21 and the exposed dissolving surface of the chemical 13. The spray nozzle's position is adjusted by means of a screw jack 68, a push-pull cable 93, a solenoid 100, or a lever 117.

Abstract: A protective aqueous antimicrobial film forming composition that can be applied to dairy animals to form a protective film. The film can be used to reduce the incidence of both contagious and environmental mastitis in dairy herds and can be formed from an aqueous composition that can contain a nonionic iodine complex, a polyvinyl alcohol composition, having a degree of hydrolysis greater than 92%, preferably greater than 98%, and a thickener. The aqueous mixture can be applied to udder and teats of dairy herds to form a protective coating that can prevent infection from staphlococcus, streptococcus, klebsiella and other pathogens. The film can be removed using water in a convenient short period of time permitting efficient milking operations. After milking, the composition can be reapplied to the herd and can protect the herd from mastitis until the herd is again milked.

Abstract: A method for dispensing solid rinse aids. The dissolved solid rinse aid is dispensed from a dispenser (100) to a solution tank or reservoir (40) which uses the heat of a high temperature warewash machine (10) to prevent bacterial or microbial growth and degradation of rinse aid solutions held within the reservoir (40). The dispenser (100) is a solid rinse aid dissolving unit that is preferably a gravity feed device dispensing solutions to the solution tank (40) located within the warewash machine (10). The dispenser (100) is fed with hot tap water or final rinse water to dissolve the solid rinse aid.

The aqueous rinse solution obtained by diluting the rinse aid with water is compatible with thermoplastics such as polycarbonate and polysulfone.

Abstract: The invention relates to a coating composition film or barrier layer containing an inorganic salt composition having a phosphate and a carbonate source and a surfactant composition. The aqueous coating can be applied to surfaces in food preparation units. The compositions of the invention can be used in methods for coating hard surfaces of food preparation units by applying the aqueous material through a spray or other aerosol apparatus to form a uniform coating. Upon drying, the water from the coating can evaporate leaving an organic/inorganic film which can support baked-on food soil and promote easy removal.

Abstract: A multiple product dispensing system includes a plurality of use solution dispensers and a controller for selecting one of the dispensers according to a preset regimen, e.g., selecting different dispensers on different days of the week. Each dispenser dispenses a controlled concentration of use solution using a diluent delivery apparatus that delivers a diluent to form a liquid concentrate from a solid chemical composition, and to form make-up diluent for diluting the liquid concentrate and forming a use solution of controlled concentration. A foam reducer reduces the kinetic energy of the make-up diluent prior to mixing with the liquid concentrate to reduce foaming. An unskilled operator may operate the dispensing system to dispense a use solution of carefully controlled concentration, and the controller will automatically select the proper dispenser according to the preset regimen, without any additional input on the part of the operator.

Abstract: A peroxyacid antimicrobial concentrate and use composition is provided comprising a C.sub.5 peroxyacid in combination with a C.sub.1 14 C.sub.4 peroxyacid, a C.sub.6 -C.sub.18 peroxyacid, or mixtures thereof. The combination of these peracids produces a synergistic effect, providing a much more potent biocide than can be obtained by using these components separately. Other components can be added to the composition such as hydrotrope coupling agents, stabilizers, etc. An effective antimicrobial use solution is formed at low concentrations when the concentrate composition is diluted with water. Sanitizing of substantially fixed, "in-place" processing lines in dairies, breweries, and other food processing operations is one utility of the composition.

Abstract: A pH greater than 7 aqueous ozonized cleaning composition can be used for cleaning a tenacious residue or film from solid surfaces. The cleaning properties can be potentiated by additive materials. Ozone, generated by electrical discharge, can be blended into effective aqueous cleaning compositions that can efficiently clean proteinaceous, oily or carbohydrate soil from a variety of surfaces. Immediately after ozone generation, the ozone containing gas stream comprising ozone and the residual air is injected through a hose into an aqueous potentiating additive containing carrier solution, forming a cleaning solution which is applied immediately to a soiled solid surface to remove a contaminating residue or film.
