  • Publication number: 20110210184
    Abstract: Various spray devices are presented for mixing two media. A device can include a housing, a first supply line for supplying a first medium, a second supply line for supplying a second medium, and a flow channel leading to a nozzle. The first and second media, for example, a gas and a liquid, respectively, can be mixed in various ways. Following such mixing, the mixed media are guided to an outlet nozzle or bore, and ejected. Using injection molding techniques, very fine grooves can be made in an exemplary spray nozzle device, by appropriately fashioning an injection mold. By carefully controlling the size, shape and dimensions of such grooves, and the pressures at which the two media are fed to the spray nozzle device, a correct ratio of air to liquid can be precisely maintained, which is key to obtaining a desired spray or foam as to droplet size, droplet speed, and type of spray, mist or foam.

  • Patent number: 7992809
    Abstract: Provided is a manual air-actuated spray paint apparatus and associated method for evenly disbursing paint in a controlled manner. Such an apparatus preferably includes a portable reservoir for holding the paint therein and a hand-actuated paint applicator removably coupled thereto. A mechanism for simultaneously discharging a single stream of paint and a volume of air may also be included. A discharge spout is removably mated to and in fluid communication with the paint applicator for mixing the single paint stream and the volume of air as they pass through the spout. A trigger is pivotally mated to the housing and is articulated between tensioned and released positions to activate the paint discharging mechanism. When the trigger is engaged, the paint is directed upwardly out of the reservoir and travels out the discharge spout to be applied to the surface intended to receive the paint.

  • Publication number: 20110147491
    Abstract: An internal mix air atomizing spray nozzle assembly comprising a nozzle body with a liquid discharge orifice defined by a relatively small diameter nose portion and an air cap having a central opening disposed in surrounding relation to the nose portion for defining an annular pressurized air passageway surrounding the liquid discharge orifice. To facilitate intermixing of liquid particles discharging from the air cap discharge orifices and for reducing negative pressures between the discharging flow streams, the air cap has an internal mixing chamber larger in diameter than the annular pressurized air discharge orifice and is formed with a plurality of circumferentially spaced discharge orifices oriented in skewed relation to a central axis of the nozzle. In the illustrated embodiment, the internal mixing chamber is defined by a cylindrical cavity within the air cap and a separate insert mounted in an upstream end of the air cap.

  • Patent number: 7950594
    Abstract: An ultrasound apparatus capable of mixing and/or atomizing fluids is disclosed. The apparatus includes a horn having an internal chamber, containing at least one free member, through which fluids to be atomized and/or mixed flow. Connected to the horn's proximal end, a transducer powered by a generator induces ultrasonic vibrations within the horn. Traveling down the horn from the transducer, the ultrasonic vibrations induce the release of ultrasonic energy into the fluids to be atomized and/or mixed as they travel through the internal chamber. As the ultrasonic vibrations travel through the chamber, the fluids within the chamber are agitated and/or begin to cavitate, while the free member moves about the chamber, thereby mixing the fluids. Upon reaching the front wall of the chamber, the ultrasonic vibrations echo off the front wall and pass through the fluids within the chamber a second time, further mixing the fluids.

  • Patent number: 7938341
    Abstract: A miniaturized aerosol jet, or an array of miniaturized aerosol jets for direct printing of various aerosolized materials. In the most commonly used embodiment, an aerosol stream is focused and deposited onto a planar or non-planar target, forming a pattern that is thermally or photochemically processed to achieve physical, optical, and/or electrical properties near that of the corresponding bulk material. The apparatus uses an aerosol jet deposition head to form an annularly propagating jet composed of an outer sheath flow and an inner aerosol-laden carrier flow. Miniaturization of the deposition head facilitates the fabrication and operation of arrayed deposition heads, enabling construction and operation of arrays of aerosol jets capable of independent motion and deposition. Arrayed aerosol jets provide an increased deposition rate, arrayed deposition, and multi-material deposition.
