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 dispenser (10) and method for washing dishes and utensils in a dishwashing machine are disclosed. The dispenser (10) is comprised of a container (11) and lid (12), the dispenser containing a solid detergent composition (13). A slot (23) in a side wall (17) and baffle (26) allow for controlled drainage of the detergent solution. The lid (12) has a plurality of openings (18) through which water from the dishwashing machine enters, so as to dissolve the solid detergent (13). The dispenser (10) is positioned within the washing chamber (20) of a dishwashing machine (19).
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 multiple product dispensing system (100) includes a plurality of use solution dispensers (10a, 10b, 10c) and a controller (110) for selecting one of the dispensers (10a, 10b, 10c) according to a preset regimen, e.g., selecting different dispensers on different days of the week. Each dispenser (10a, 10b, 10c) dispenses a controlled concentration of use solution using a diluent delivery apparatus (13) that delivers a diluent to form a liquid concentrate from a solid chemical composition (22), and to form make-up diluent for diluting the liquid concentrate and forming a use solution of controlled concentration. A foam reducer (24) 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 (100) to dispense a use solution of carefully controlled concentration, and the controller (110) will automatically select the proper dispenser according to the preset regimen, without any additional input on the part of the operator. Therefore, the likelihood of operator error occurring is greatly reduced by the automatic selection of the proper dispenser (10a, 10b, 10c) and the control over use solution concentration.
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:
A dispenser (100) for dispensing a chemical product that is dissolved by diluent. The dispenser includes a package (170) having a diaphragm, or fingered collar (180) attached to its opening. The diaphragm (180) has a plurality of flexible members or flexible fingers (185). The dispenser may utilize an injection manifold (109) that is sized and configured to be positioned on a washing machine top proximate the gap between the washing machine's top and lid. Still further, the invention includes a low level chemical product indicator. The indicator includes a focused light source (98a). The focused light source is a high intensity light emitting diode having a viewing angle of less than 6 DEG and an intensity of above 10,000 mcd. The dispenser also includes an apparatus and method in which a dispensing time of a dispenser is dynamically varied in response to diluent temperature during operation of the dispenser.
Abstract:
The invention relates to an apparatus for diluting liquid concentrate materials to liquid use solutions. An aspirator system (16) is adapted to receive a container (11a) of liquid concentrate in a reservoir (10). The reservoir contains means (13) to open the liquid concentrate. Additionally the reservoir contains means to support the liquid concentrate during addition of concentrate to the reservoir. When empty, the liquid concentrate bottle can be placed in a reservoir for the empty container (11b). The receiver has filling means for the container that can deliver dilute use solution to the container. The liquid concentrate container and the dilute use solution container are substantially identical. The apparatus is controlled using a flow controller (14) that activates liquid diluent causing the liquid diluent to pass through the aspirator drawing concentrate at a fixed dilution ratio. The aspirator can be used in a station with multiple apparatus, each adapted to a particular liquid concentrate and dilute use solution. The typical container for such a station comprises a plastic bottle (11) having a fitment adapted to the receiver opening means. The preferred container for the liquid concentrate contains a fitment comprising a closure for the bottle opening having impressed into the closure a circular indent operatively connected with a thick hinge member. When inserted into the reservoir, the opening means causes the fitment to fail at the circular indent resulting in a clean separation of the circular portion from the closure permitting the contents of the concentrate container to drain into the reservoir.
Abstract:
The present invention is directed to a clinic sink system and method for precleaning soiled articles, such as diapers, hand towels, washcloths, personal linens, general bed linens, and bedpans soiled with human waste products. A method is provided which is capable of precleaning soiled articles prior to cleaning in a conventional washing machine. In a preferred embodiment, odors may be controlled by introducing a deodorizing agent into solution with water sprayed from a dispenser onto an article, and disease may be controlled by introducing a sanitizing agent into the solution. A preferred dispenser (10) for use therewith includes a container (18) and a base (12) which form a substantially sealed reservoir. Such a dispenser is capable of providing a controlled concentration of chemical product in solution.
Abstract:
A solution storage and dispensing apparatus and method of operation therefor are disclosed. The solution storage and dispensing apparatus includes a selector valve (68) and a control valve (62) which selectively output a liquid such as water to one of a plurality of storage containers (11a, 11b, 11c, 11d). Each container (11) has an aspirator (26) mounted therein which receives the water and a chemical concentrate to form a solution therein. A container is filled by selecting the container using the selector valve and actuating the control valve to dispense water to the selected container.
Abstract:
Disclosed is a dispenser (10) for use with an automatic floor scrubbing machine (75), and a method for cleaning a floor. The dispenser (10) has a solid chemical (13) which is dissolved by water spray from a spray nozzle (21). The detergent solution is then directed by a conduit (25) to a scrub brush (85). A water reservoir (83) provides water for the detergent solution, and a valve (38) directs water to a rinse conduit (37) for rinsing of the floor. After cleaning, the dirty water or detergent solution is carried through conduit (36) to a recovery tank (84).
