A paint gun for atomizing (in particular by way of compressed-air-assisted atomization) and applying a coating material such as a paint has a material-guiding part, a non-material-guiding part, and a transmitting and/or receiving device for wireless signal transmission. In order to increase the functional reliability and provide optimal operability in the environment in which the coating material is applied, the transmitting and/or receiving device for wireless signal transmission is arranged at a distance from the material-guiding part and is associated with the non-material-guiding part. Alternatively or additionally, an increased functional reliability is achieved by designing the transmitting and/or receiving device for wireless signal transmission in accordance with two different radio standards. Furthermore, a material application system comprising such a paint gun as well as a method for operating same are described.

A Wurster processor and a powder feed system are coupled via an eductor so as to supply dry powder through the air diverter sleeve of the Wurster for discharging onto the circulating particles during operation of the Wurster. Agglomeration and aggregation of the particles is eliminated or minimized by isolating or separating the liquid spray by the spray gun from the dry powder.

A nozzle comprising a first light and a second light, wherein one of the lights is used to detect certain materials, such as bodily fluids, pet messes and stains and the like, while the other light is used for illuminating an area to be cleaned. The lights may be integrally incorporate into a nozzle or removably detachable therefrom.

In accordance with an example embodiment, there is disclosed herein a sprayer operable to dispense fluid from a fluid reservoir, such as a paint reservoir. The sprayer comprises a rechargeable battery pack that can be employed to provide power to a pump. The pump provides air to a nozzle assembly that is mixed with fluid from the fluid reservoir and dispensed via the nozzle assembly. In particular embodiments, the nozzle assembly comprises a disposable tip insert.

Aspects of the present invention provide a method and an apparatus for drying a region of a human body. The apparatus include a toilet seat assembly, and a drying nozzle assembly having one or more drying nozzle units with one ore more retractable elements adapted to deliver air at a predetermined temperature to the region of the human body, and a fan connected to the one or more drying units. In one aspect, the drying nozzle assembly also includes a first driving motor being connected to the one or more drying nozzle units and adapted for moving the one ore more retractable elements in retracting-and-extending motion, and a second driving motor being connected to the one or more drying nozzle unit and adapted for moving the one or more drying nozzle units in three-dimensional circular rotational motion.

An adapter (14) allows direct connection of a handheld spray device (10) to paint cans (12, 12A, 12B, 12C), of varying dimensions. The adapter (14) includes a cage (60) for holding the paint can (12, 12A, 12B, 12C), a cap (62) that connects the cage (60) to the handheld spray device (10), and a gasket (64) that seals the open upper end of the paint can (12, 12A, 12B, 12C) to the cap (62). The adapter (14) may also include a suction tube extension 66 that is connectable between the pump inlet (52) and the suction tube (54) of the spray device (10).

A pass box configured to accommodate and decontaminate an article by concentrating a mist of decontamination agent on an article's surface and to reduce a duration of aeration operations. The box includes a decontamination chamber, an aeration chamber in which residue of the decontamination agent is removed from the article's surface, a decontamination agent supply device, a decontamination agent control device, a moving device configured to reposition the article, and an air supply and exhaust device. The decontamination agent supply device converts a chemical into the mist and supplies it into the decontamination chamber. The decontamination agent control device includes vibration boards that are adjacent to internal wall surfaces of the decontamination chamber and that are ultrasonically vibrated to generate sound flows in the vertical direction thereby pressing the mist with acoustic radiation to concentrate the mist on the external surfaces of the article.

An atomizing spray device includes a housing having plural inlets and one or more outlets fluidly coupled with each other by an interior chamber. The inlets include a first inlet shaped to receive a first fluid and a second inlet shaped to receive a slurry of ceramic particles and a second fluid. The interior chamber in the housing is shaped to mix the first fluid received via the first inlet with the slurry received via the second inlet inside the housing to form a mixture in a location between the inlets and the one or more outlets. The interior chamber in the housing also is shaped to direct the mixture formed inside the housing as droplets outside of the housing via the one or more outlets such that, based on a discharged amount of the first fluid in the droplets, the first fluid promotes evaporation of the second fluid as the droplets traverse from the housing toward a surface of a component.

A nozzle includes a main chamber defining a first internal space, a first inlet defined in a first end of the main chamber to couple to a material sprayer, a second inlet to receive a solid material into the main chamber, and an outlet defined in a second end of the main chamber. The first inlet upstream from the second inlet to allow a fluid material to enter the main chamber before the solid material. The main chamber configured to mix the solid material with the fluid material.
