Abstract:
An ultrasonic mixing system having a treatment chamber in which at least two separate phases can be mixed to prepare an emulsion is disclosed. Specifically, at least one phase is a dispersed phase and one phase in a continuous phase. The treatment chamber has an elongate housing through which the phases flow longitudinally from a first inlet port and a second inlet port, respectively, to an outlet port thereof. An elongate ultrasonic waveguide assembly extends within the housing and is operable at a predetermined ultrasonic frequency to ultrasonically energize the phases within the housing. An elongate ultrasonic horn of the waveguide assembly is disposed at least in part intermediate the inlet and outlet ports, and has a plurality of discrete agitating members in contact with and extending transversely outward from the horn intermediate the inlet and outlet ports in longitudinally spaced relationship with each other. The horn and agitating members are constructed and arranged for dynamic motion of the agitating members relative to the horn at the predetermined frequency and to operate in an ultrasonic cavitation mode of the agitating members corresponding to the predetermined frequency and the phases being mixed in the chamber.

Abstract:
A dryness indicator includes a wicking strip continuous between a reservoir end and an opposed open end; a liquid-impermeable top layer disposed on one side of the wicking strip; and a liquid-impermeable bottom layer disposed on the opposite side of the wicking strip, wherein the top layer is affixed to the bottom layer to at least partially enclose the wicking strip, and wherein the indicator is configured such that the open end of the wicking strip can be placed in liquid communication with an object or surface. The dryness indicator also includes a reservoir including an oil-based colorant with the potential to be in liquid communication with the reservoir end of the wicking strip, wherein the wicking strip is configured such that colorant wicking from the reservoir end and an unreacted water-based fluid wicking from the open end meet to define a timing line.

Abstract:
A web article (28) includes at least a first fibrous layer (36) laminated with a first facing surface (72) of at least one polymer film layer (38). The first fibrous layer can include a first quantity of cellulosic fibers. The first fibrous layer and the at least one polymer film layer have been configured to provide a target web (26), which has been moved at a selected web speed. A rotating anvil roller (34) and counter-rotating pattern roller (32) have been urged together to provide a selected nip force value. Additionally, the target web has been moved at the web speed through a nip region (30) between the anvil roller (34) and pattern roller (32) to provide an operative first bond between the first fibrous layer (36) and the at least one film layer (38).
