Abstract: An apparatus providing improved dispensing of liquid-additives such as soap, shampoo, or bodywash, into an existing waterline outlet in bathroom or kitchen, while optionally featuring a unique Bubblizer™-chamber enabling user to observe an eye-catching dynamic fluidic-admixture display via a 2-inch diameter preview-window, prior to emergence of the bubblized-admixture via a conventional showerhead. The SudsMix™ shower-unit version readily suspends from an existing wall-extending gooseneck-pipe where it fluidicly couples into the water-line without aid of tools. Introduction of the liquid-soap additive is initiated remotely via a pushbutton valve conveniently located at waist-level, while concealed conduit-lines feed selected additive upward from the reservoir-section to the Bubblizer™-chamber integrated into the upper portion of the wall-hugging housing. Other adaptations of the Bubblizer™-chamber are a hand-held wand-like bathing back-scrubber, and similar kitchen-sink dish-scrubber.

Abstract: The invention relates to a compressed air foam producer, wherein a fire or decontamination specific additive is injected directly into the foam forming flow supplied to the main water flow and/or the main water flow.

The foaming agent-additive-water mixture, which is produced directly on site, is mixed well together and with the main water flow ensuring a fine, uniform distribution of the additives in the compressed air foam. The thus produced compressed air foam ensures optimal, economical and environmentally friendly fire-fighting and decontamination.
