Abstract: Neutral to mildly acidic externally-applied mastitis control agents based upon antimicrobial nitroalkanols (e.g. 2-bromo-2-nitropropane-1,3-diol) can be made more effective against Pseudomonas aeruginosa through "potentiation" with an aminocarboxylic-type chelating agent. The chelating agent is believed to improve cell-wall permeability, even at a pH well below 7.

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 reusable dispenser of solid or semi-solid fabric-conditioning agent is placed in the dryer drum and tumbled with the fabrics in the dryer thereby causing some of the fabric-conditioning agent to be transferred to the fabric. The fabric-conditioning agent comprises a fabric conditioner, a softening point modifier, and a viscosity modifier. When the dryer is heated, the heat of the dryer helps cause the fabric-conditioning agent to soften and assist in its distribution over the surface of fabric with which it is brought into tumbling contact.

Abstract: A laundry method is disclosed including the step of laundering oil soiled fabric in lipophilic surfactant composition and subsequently laundering such fabric with a hydrophilic surfactant based detergent system.

Abstract: The interior of the tank of a tank truck or a tank wagon, is cleaned using a selectively removable sprayhead and the built-in delivery pump of the tank vehicle. A removable sprayhead is inserted into the interior of the tank through a manhole and connected, via the delivery pump, to an external storage source of a solvent or cleaning solution. The solvent is, for example, a mixture including a chlorinated aliphatic compound and an aromatic compound, both compounds having a freezing point below 60.degree. C. The solvent is then pumped into the tank, and the hoses normally carried with the tank truck are connected so that the delivery pump can be used to recirculate the solvent through the tank. The solvent is recirculated until the tank is clean at which time it is pumped back into its original storage tank so that it can be reused.

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: Electronic laundry machine controller apparatus for automatically synthesizing, in response to single operator program selections, complete laundry cycles or programs from laundry machine control instructions stored, independent of operator selection or control, within an electronically read memory. A read only memory is preprogrammed to store laundry machine control instructions and program synthesis instructions for compiling a large number of different laundry programs, each having laundering steps or operations preconfigured to satisfy the peculiar laundering requirements of a large number of different commercial and institutional users. Program variation select means presettable by the manufacturer or upon installation of the controller enables preselection for execution from the large number of possible laundry cycles, only those laundry machine cycles which best satisfy the user's specific laundering needs.

Abstract: Ethanolamine (preferably triethanolamine) salts of phosphate esters (i.e., phosphate esters of ethoxylated alcohols) are used as carrier or complexing agents for iodine (e.g., in preparing pre-surgical germicidal compositions). These solutions have "fast-draining" properties and are especially useful for sanitizing containers in automated or continuous-line operations.

Abstract: An improved nozzle apparatus rapidly convertible, while operating, between spray and foam forming modes of operation. An elongate rigid generally cylindrical first conduit member receives surfactant bearing solution at an inlet port thereof and directs the solution under pressure to a spray forming nozzle connected at an outlet port of the first conduit. A second elongate conduit member coaxially slidably overlies the first conduit member and is movable relative thereto between extended and retracted positions. When in its retracted position, the second conduit member exposes the spray-forming nozzle, which is then enabled to direct a spray pattern of the solution longitudinally outward from the apparatus. When in its extended position, the second conduit member encompasses the spray-forming nozzle, and aspirates the spray therefrom with air to form foam which is ejected longitudinally outward from the second conduit member.

Abstract: A non-hazardous dispenser apparatus for converting powdered detergent, including those containing active chlorine, into a concentrated detergent solution for use by a washing machine. A curved screen member retainably supports a mass of powdered detergent thereabove within a generally cylindrical container configured for mounting to the side wall of a washing machine adjacent the detergent solution carrying reservoir thereof. A single spray-forming nozzle is mounted within the container and below the curved screen for directing a uniform spray of water at substantially the entire downwardly facing concave surface of the screen member. Only that detergent carried immediately above the screen member is wetted by the spray and passes in solution through the screen, after which it is collected and directed by a collecting portion of the container, into the washing machine reservoir.

Abstract: The disclosed foamable phosphatizing compositions comprise a phosphatizing agent combined with a high-foaming surfactant. When mixed with a gas such as air, the composition provides a relatively stable foam which adheres to overhead or inclined or vertical metal surfaces. When the foam has been in place on the metal surface for a certain minimum dwell time (and the coating weight has reached at least 10mg/ft.sup.2), the phosphatizing composition is rinsed off or is permitted to drain off. By procedures which involve reproducible laboratory tests, maximum and minimum dwell times or contact times can be determined even for use in the field under poorly controlled conditions. As a result, the control over the resulting phosphate coating weights is comparable to the control obtainable in immersion techniques or tunnel sprayer techniques.

Abstract: A system for converting powdered detergent in a shipping container into a concentrated detergent solution and for maintaining a predetermined volume of the solution available for use by a remotely located washing apparatus. A chassis defines a reservoir suitable for holding concentrated detergent solution and has an inlet port opening into the reservoir. A curved screen member is continuously mounted across and extends into the open mouth end of a detergent-filled container. A cradle assembly pivotally positions the container and screen in inverted position over the inlet port to the reservoir such that the curved screen retainably supports the detergent within the container. A single nozzle is mounted at the inlet port for uniformly directing a spray of solution from the reservoir against substantially the entire downwardly facing surface of the screen, dissolving a portion of the detergent carried thereby, which passes in solution through the screen and into the underlying reservoir.

Abstract: The disclosed organic ammonium phosphate salt concentrates can be diluted with water in the weight ratio of from 1:5 to 1:250 (concentrate:water) and used in bath, spray, or steam phosphatizing (sometimes called "phosphating"). These concentrates and the resulting diluted solution are reasonably pH-stable in the pH range of 3.0 to 5.5. Preferably, the concentrates contain a buffer, various surfactants, and, particularly for low temperature use (e.g. 20.degree.-55.degree. C.) an accelerator system. The concentrates are well suited to automatic dispensing of a phosphatizing spray or make-up solution (for a bath); they are efficient at low temperatures; and they have good storage stability.

Abstract: A detergent dispensing system for sequentially and automatically injecting various liquid products (e.g., detergents, fabric conditioners, neutralizers, etc.) into a laundry washing machine. Each liquid product is independently connected to a venturi-aspirator positioned within separate carrier fluid conduits (e.g. water conduits) and the product is drawn into the respective carrier fluid conduits upon passage of carrier fluid therethrough. Electrical control circuitry, including electrical timing apparatus, triggered by a signaling device synchronized with the machine washing cycle selectively actuates and deactuates a solenoid-operated valve positioned upstream of each venturi-aspirator so as to allow injection into the carrier fluid of a predetermined quantity of each liquid product at the desired point in the machine cycle.

Abstract: A fluid metering device mixes a predetermined quantity of a first fluid with a larger quantity of second fluid supplied to the device at a higher pressure on each cycle. The pressure of the second fluid provides the force necessary to motivate a first pumping means which on movement to an `outlet` position within a housing displaces the mixed fluids on an outlet side of the first pumping means to their destination. Movement of the first pumping means actuates a second pumping means which pumps a predetermined quantity of the first fluid into the housing on each cycle. On the maximum pumping stroke of the first pumping means being reached at the `outlet` position, a passage is opened in the first pumping means which is then restored to an `inlet` position, the second fluid in the housing passing through the passage during such restoration and thus being available for dispatch on the next pumping stroke.
