Abstract: A clog-resistant injector spray nozzle allows relatively unobtrusive insertion through a small access aperture into existing ductwork in occupied buildings for atomized particulate sealing of a ductwork. The spray nozzle comprises an easily cleaned and easily replaced straight liquid tube whose liquid contents are principally propelled by a heated propellant gas, such as heated air. Heat transfer is minimized from the heated propellant gas to the liquid tube until they both exit the injector, thereby greatly reducing the likelihood of nozzle clogging. A method of duct sealing using particles driven by heated propellant gas is described, whereby duct-sealing operations become both faster, and commercially practicable in inhabited commercial and residential buildings.

Abstract: In an atomizer device for the production of a liquid-gas mixture (4), the mixture (4) is introduced, particularly for compression, into a nozzle arrangement (3) in which the kinetic energy of the mixture (4) is in large part converted into compression energy by a pressure rise of the air. The atomizer device (2) includes a central air feed (16) and a nozzle chamber (18) for the supply of liquid surrounding the air feed. At or in the atomizing device, means (17) are arranged in the nozzle chamber for producing a swirled liquid flow in the nozzle chamber (18), and the swirled liquid flow emerges via a nozzle aperture (19) surrounding the air feed.

A supersonic jet of gas is emitted from a nozzle and shock waves are developed in the jet. In one embodiment the supersonic jet is directed into a shock chamber. Liquid or micronized powder material is introduced into the supersonic jet to form an aerosol. In one embodiment, smaller aerosol particles are separated from larger aerosol particles with a separator. In another embodiment, the produced aerosol is contained in an aerosol storage chamber prior to inhalation by the users.

Abstract: A three-stream atomizing nozzle that has an air stream divider that separates the atomizing air from the source into three streams. The first stream is a straight air stream staying closest to and around the atomized water jet. The second stream is a swirl running around the first straight stream. The third stream is also a straight stream that wraps around the first straight stream and the second swirl. The nozzle also has a mixing chamber in which the three air streams are mixed together for the atomizing purpose. From the combination of the three air streams the nozzle can produce fine water droplets that are suitable for many uses and more importantly creates a tailorable water mass profile. The mass profile can be tailored into a shape that is close to a square shape which creates minimal coupling between adjacent zones.
