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: The invention is an alkaline cleaning system which includes an alkaline detergent composition having a pH greater than 10.5 when diluted to a 1 wt-% aqueous solution, and an alkali stable continuous polymeric film dispersible or soluble in aqueous liquids covering the detergent composition. The invention also includes methods of using the alkaline cleaning system by applying an aqueous diluent automatically (by machine) or manually through partial or complete dissolution of the film covered solid.

Abstract: An apparatus and method for programming a detergent controller to vary the detergent concentration set-point according to the time of day and to achieve detergent concentration levels quickly without incurring overshoot. Thus, the present invention insures that the warewashing machine is operated at optimum efficiency and cost. To vary the set-point according to the time of day, the invention combines the features of a microprocessor, a clock and a controller into one unit. The user enters the time setting and set point into the controller. The microprocessor then compares the real-time clock signal with the user time settings and outputs an appropriate set-point value from the microprocessor to the controller. To achieve detergent concentration levels quickly without incurring overshoot, the controller senses the detergent concentration and dispenses the proper detergent level to the warewashing machine according to a predetermined detergent feed time based on the previous response time and the programmed set-point. Thus, the controller can change the response function if and when conditions change.

Abstract: The invention is a solid chemical concentrate system of at least two cooperative shapes. The first shape is an inwardly curved bar having an inner opening. The second shape is an insert which is capable of interlocking with the bar by insertion into the bar inner opening. The solid chemical concentrate provides chemical systems having active constituents which may be the same, different but compatible or functionally and chemically incompatible combined within one matrix to provide at least one substantially continuous surface. The system may also comprise an aqueous soluble or dispersible polymeric film cover.

Abstract: A system for proportioning and dispensing concentrated liquid products is disclosed. The components of the system's first embodiment are mounted upon a cart (12). A concentrate solution tube (14) is interconnected to a dilution assembly (61) containing an aspirator (26). A water supply assembly (69), containing a valve (75) and backflow preventer (74), is connected to the aspirator assembly (26) when dilution of the concentrated product (13) is desired. A discharge tube (68) carries the diluted product from the aspirator assembly (26) to a container (60). The system's second embodiment has a spray gun assembly (150) containing an aspirator (167), a valve (166), and preferably though not necessarily, a backflow preventer (165). The concentrate pickup tube (114) attaches to the spray gun assembly (150) with a releasable connector (170). The spray gun assembly has a rigid delivery tube (153) for dispensing to large containers (160), and a nozzle tip (180) for attachment to an inlet port (119) of a jug (111). Also disclosed is a method for dispensing and handling solutions.
