Abstract: Disclosed is a method and apparatus (10) for dispensing powdered pesticide (13). A housing (11) is separated into an upper chamber (12) and lower chamber (51) by a porous media layer (19). The powdered pesticide (13) is contained within the upper chamber (13) and is fluidized when compressed air enters the dispenser from air inlet line (18). The fluidized pesticide is dispensed through outlet line (34) and nozzle (36) when a control valve (50) is activated. Only particles having a size smaller than a predetermined size are dispensed; the remaining, relative large pesticide particles remain in the upper chamber until physically removed.

Abstract: A solid cast warewashing detergent composition that can be formed, cast and distributed within a container or capsule. The cast composition which has improved cleaning, bleaching and dissolution properties, can be made by forming a hydration mass of an alkali metal metasilicate, an alkali metal phosphate, an alkali metal hypochlorite, chlorinated alkali metal phosphate, and sufficient water of hydration to harden the mass. Such cast detergent compositions can be attached to dispensing mechanisms in warewashing machines and can generate, as a result of the action of a stream of water on the cast material, a high performance warewashing solution.

The composition comprises a source of alkalinity, a water-conditioning vinyl polymer with pendant --CO.sub.2 H groups, a soil-dispersing phosphinopolycarboxylic acid, and a water-conditioning organic phosphonate.

Abstract: A dispenser suitable for dispensing multiple solutions to, preferably, multiple utilization points. A laundry washing system (18) according to the invention includes a dispenser (20) which dispenses a plurality of cleaning solution to a plurality of washing machines (72) through a single common conduit (25). Conduit (25) is flushed after dispensing one solution but before dispensing a second chemically incompatible solution. A preferred dispenser (20) is capable of servicing multiple laundry machines (72) using a first-in first-out approach wherein the machines request service from a control system (74) which temporarily disables any "late-comers" until the appropriate solution can be dispensed to the machine (72) making the first, or highest priority, request.

Abstract: A dishwashing apparatus designed in such a manner as to have one incoming waterline and self cleaning filters. Solid additive sources are situated in containers mounted on top of the dishwashing apparatus and fed with water by means of a pump. A flip-top solid detergent dispenser comprising a base having a funnel-shaped interior, a nozzle positioned within the interior of the base, and a detergent container support connected by a hinge to the base can be mounted on the dishwashing apparatus. The detergent container support is designed to hold only a particular shaped detergent container and to prevent dripping of detergent solution upon the user. A circular metallic ring having a plurality of holes is situated around the funnel-shaped interior of the base. Water is flushed through the holes of the circular metallic ring at designated times to purge one of the filters of air and to insure that the detergent is rinsed down through the funnel-shaped interior of the base.

Abstract: Disclosed is a cleaning-in-place valve actuator (23) for cleaning a soft serve shake machine (10). The valve actuator (23) is mounted upon the front of the soft serve shake machine (10), and a motor (20) moves a series of mechanical linkages (15, 11) so that a shifting fork (8) pivotally and reciprocally rotates. The forked ends (64) of the shifting fork (8) attach to levers (42) on the soft serve shake machine (10) and cause the lever (42) to move back and forth. The movement of the lever (42) opens and closes a draw valve (40) which controls flow to the machine's outlet nozzle (31), so that the cleaning solution can flow to all parts of the soft serve shake machine (10) for thorough cleaning.

Abstract: Aqueous processes and compositions of the invention for obtaining a "stone-washed", distressed or "used and abused" look in clothing, particularly in the panels and seams of denim jeans and jackets involve compositions that are stone-free that avoid mechanical abrasion of the fabric. In particular, the process and composition of the invention used to obtain the distressed, "stone-washed" or "acid washed look" are free of common pumice or pumice-bleach compositions, used in large institutional-size laundry machines, and rely solely on the chemical action of aqueous treatment compositions. The aqueous treatments can be made from liquid or solid concentrates.

The solid cast detergent, surrounded on all but its upper surface by the mold, is used in automatic washing machines having a dispensing device designed to dispense a liquid aqueous detergent formed from the solid cast detergent using an impinging liquid spray. The liquid aqueous detergent flows out of the dispensing device generally simultaneously with its formation in the dispenser. The cast detergent composition includes an alkaline hydratable chemical and optionally further includes one or more preformed cores or plugs comprising an available chlorine source, a defoamer, or the like.
