Abstract: A dispensing assembly for dispensing a mixture of fluids is provided. In some embodiments, the dispensing assembly includes a first valve for selectively permitting fluid flow to a mixing chamber in which a second fluid is introduced, wherein the valve is actuated between open and closed positions responsive to fluid pressure downstream of the mixing chamber. In such embodiments, the fluid pressure downstream of the mixing chamber can change based upon whether fluid is dispensed from a spray gun, wand, nozzle, or other dispensing head of the dispensing assembly.

Abstract: An eductor for mixing two liquids wherein the eductor includes a closed or non-air gap back flow prevention member. The vacuum profile of the eductor is altered by changing an opening in a passage portion to controllably divert water flow around the venturi tube or diverting the water without the opening. This affords the changing of the vacuum profile without redesigning the entire eductor.

Abstract: A foam producing nozzle for attachment to a spray nozzle which is readily attached and removed therefrom. The foam producing nozzle has air channels which do not lend themselves toward leaking. The dilution rate of the chemical concentrate is not affected by the foam producing nozzle.

Abstract: A mixing and dispensing apparatus wherein a liquid concentrate is metered into a diluent stream of an eductor in a precise manner. A needle valve is employed in conjunction with a cam member and the cam member includes slopes of varying degrees. In this manner, a wide range of dilution rates can be accomplished with only a single revolution of the needle valve. The apparatus is particularly useful in mixing and dispensing chemical concentrates such as cleaning and sanitizing materials.

Abstract: A battery operated atomizer device comprising, in a housing (22), a liquid reservoir (30) from which a capillary type liquid delivery system (38) extends to contact a piezoelectric actuator an atomization plate assembly (34), the assembly (34) being supported by means of wire-like elements (36) in cantilever fashion over the liquid delivery system, the liquid delivery system comprising an outer tubular member (52) and a solid rod (56) which have facing surfaces configured to define between them, longitudinal capillary liquid passages.

Abstract: A plug and wickholder is configured to be reliably sealed to the neck of a bottle which contains a liquid to be atomized and to a cap which seals the bottle during storage. The plug and wickholder includes a first generally tubular wall which contains a wick and which fits tightly into a cap sealing wall, and it further includes a generally cylindrical sealing wall which fits tightly into a bottle neck. A second generally vertical tubular wall is interposed between the first generally tubular wall and the generally cylindrical sealing wall.

Abstract: Disclosed is an improved mixing eductor (10) of the type wherein the primary liquid (17), e.g., water, is in a main stream (201) flowing in a downstream direction. A venturi tube (51) is in the eductor (10) and has an annular sharp edge (131) in the main stream (201), thereby dividing such stream (201) into a primary stream (179) and a secondary stream (181) around the primary stream (179). The eductor (10) has an air gap (103) and a flow guide (47) downstream thereof. In a specific embodiment, the flow guide (47) is annular around the venturi tube (51) and the tube (51) and the guide (47) are in spaced telescoped relationship. Several embodiments of the eductor (10) and a new method for mixing liquids are disclosed.
