Abstract: A cleaning system has a holder for holding one or more bottles. A precision metered dispenser is selected based on a viscosity of a concentrated cleaning solution to be dispensed and a desired dispensing quantity. Graphical pictorials are provided for illustrating instructions for dispensing and diluting the concentrated cleaning solution.

Abstract: A concentrated non-aqueous cleaning solution having a long shelf life includes an ester and an anhydrous surfactant. The ester is the active ingredient for dissolving graffiti, grease and other contaminants. The ester can be one of or a mixture of dimethyl glutarate, dimethyl succinate, dimethyl adipate, ethyl lactate, and a methyl ester extracted from soybean oil. The anhydrous surfactant is preferably alcohol ethoxylate. The ester in the concentrated solution does not degrade into an acid and alcohol as long as the solution is not mixed with water. This allows the concentrated solution to be shipped and stored and remain efficacious. The concentrate can be diluted with water immediately prior to use. Diluting before use makes the graffiti cleaner less expensive and prevents damage to sensitive surfaces but does not provide long enough time for the ester to degrade.

Abstract: The present invention is a portable dilution cleaning system for applying any detergent and/or rinsing product directly onto surfaces being cleaned. The system connects very quickly to a faucet (145) using a quick disconnect assembly (99) and a dispensing and rinsing gun (200, 200′ or 300) sprays use solutions and rinse water directly onto the surfaces to be cleaned. The quick disconnect assembly (99) includes a quick disconnect with a back flow prevention (100) and a quick disconnect aerator (147). The quick disconnect aerator (147) connects to the faucet (145) and the quick disconnect with a back flow prevention (100) connects to the quick disconnect aerator (147). A hose (256) interconnects the quick disconnect assembly (99) and the dispensing and rinsing gun (200, 200′ or 300).

Abstract: A liquid floor finish application applicator comprising a mobile unit and a wand unit. The mobile unit comprises a handle and wheels. In the cart is positioned one or more sources of floor finish, and a pump for delivering the floor finish to a length of liquid conduit. The wand comprises a distribution head typically a mop installation. The wand also comprises a spray head that can deliver the liquid floor finish to the floor. The conduit is in liquid communication with the wand. The spray head is configured to avoid dripping between finish application. The drip free head results from the aperture size of the spray aperture surface. The lengthy conduit between the cart and the wand permits ease of application by a two man team. A first man operates the cart while a second man operates the wand.

Abstract: A method for dispensing and handling chemical solutions by using a dispensing station. The dispensing station includes a cabinet having a fill compartment and at least one concentrate bottle compartment. The cabinet's top wall has a funnel for supporting a dilution gun. The gun is in fluid communication with a water source and has a removable insert containing an aspirator. The insert's outlet tube fits within the cabinet's funnel. A pickup tube extends from the concentrated chemical solution to the gun. A use container such as a spray bottle is sized and configured to fit within the fill compartment. In the preferred embodiment, the concentrate container has a plurality of grooves which are sized and configured to correspond with a plurality of ribs within the concentrate compartments. Additionally, the concentrate compartment's lower portion forms a track to accommodate a bottom portion of the concentrate 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).

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. A pair of cam members 50, 51 adjust the vertical position of the solid chemical 13 with respect to the spray nozzle 21. In a preferred embodiment, a visual indication of the concentration settings is provided, with the concentration settings corresponding to the nozzle-to-eroding surface distance.

Abstract: A system for diluting and dispensing concentrated liquid products is disclosed. The system includes a dispensing device (10, 150) containing a removable proportioning means such as an aspirator assembly (40, 154). A concentrate pickup tube (114) attaches to the dispensing device and is in fluid communication with the aspirator assembly. The dispensing device can utilize a rigid outlet tube (20, 159) which is removably attached to nozzle tip (18, 158) for dispensing to large containers. Also disclosed is a method for diluting and dispensing chemical solutions using the dispensing device of the invention.

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).
