    Abstract: A fast-set, plural component, spray applicator includes a stationary mix chamber to eliminate dynamic metal-to-metal high pressure fluid sealing. The stationary mix chamber mixes the plural components before dispensing the mixed components from the spray applicator. The spray applicator includes fluid needles configured to engage and disengage seals to perform the fluid valving. Needles control both fluid and air flow to the stationary mix chamber.

    Abstract: This application discloses the hand sanitizer device which includes at least outlet tube and foaming sub-assembly. Said outlet tube's end connects with said foaming sub-assembly via the water tube fitting, allowing gas-liquid mixture to transmit through said outlet tube, said water tube fitting and to said foaming sub-assembly. Said foaming sub-assembly includes shell and foaming part, wherein said shell has the through hole and internal threads at one end. Said shell with internal threads connects with said water tube fitting with external threads at the end. The other end of said shell has the contact part extending internally from the other end's edge of said through hole, within which said foaming part is located and pressed between said contact part and the end of said water tube fitting. Technical proposals from this application can facilitate the changing, maintaining and cleaning the foaming part of the hand sanitizer device for users.

    Abstract: The device includes a vessel for filling with a mixture of water and a foam-forming component. The vessel comprises a device for injecting air into the foam generation mixture. The device has at least two vessels arranged one above the other in a vertical direction in a leveled form for filling with the mixture and for injecting air into the foam generation mixture. The vessels are open towards an outlet region in such a way. The foam generated in the vessels is merged in the outlet region.

    Abstract: A print head comprising nested chambers for in-situ reactant formation is disclosed. The print head comprises a first chamber nested within a second chamber. The first chamber comprises a first nozzle, the second chamber comprises a second nozzle. The first nozzle is substantially coaxial with the second nozzle. A susceptor to convert electromagnetic energy to heat is within the first chamber. The susceptor comprises one or more openings extending between the upper portion and the lower portion. The susceptor may be heated by induction heating or by optical heating to vaporize a precursor substance within the first chamber. The vapor may react with a reactive gas flowing through the first chamber or expand through a nozzle into a second chamber where the vapor may react with the reactive gas, forming nanoparticles. Patterned films may be written onto a two-dimensional or three-dimensional surfaces.
