Abstract: A cleaning apparatus includes a fluid reservoir assembly and a removable cleaning pad cartridge assembly. The reservoir assembly includes a reservoir body defining a closed fluid reservoir, a pump device, and at least one outlet valve which allows fluid to exit the reservoir when the reservoir is pressurized by the pump device. The cartridge assembly includes a cleaning pad support body, a cleaning pad support base, and a cleaning pad defined by an outer edge area. The support body and base are immovably joined together. The support body includes a downward-projecting outer lip, and the support base includes an upward-projecting outer flange. The outer lip of the support body is inward of the outer flange of the support base, and the outer edge area of the cleaning pad is between the outer lip of the support body and the outer flange of the support base.

Abstract: The present disclosure provides apparatuses for cleaning and/or hair gathering. The devices can include first and second components configured to form a liquid dispenser and define a reservoir when operatively engaged. The second component can be configured as a multi-layered absorbent pad wherein one of the layers can comprise a substantially rigid, porous, and/or thick material, and another layer can comprise a less rigid, less porous, and/or thinner layer than the one layer. The present method provides for applying pressure to within a liquid-dispensing reservoir to force liquid from the reservoir to one substantially rigid, porous, and/or thick layer and then to another less rigid, less porous, and/or thinner layer of a multi-layered absorbent pad. The second layer of the multi-layered absorbent pad can be applied to materials for cleaning and/or hair gathering.

Abstract: The instant invention is drawn to an apparatus and process for, direct ultrasonic mixing of a sample by use of an ultrasonic probe, in combination with sample conveying and/or sample analysis, thereby providing: convenient automated flexible sample preparation (e.g. mixing), conveying and/or analysis; and/or greater accuracy and precision of analysis than was previously achievable.
