A cleaning device for atomizing and spraying liquid in two-phase flow comprising a nozzle provided with multiple liquid bypass pipelines each having liquid guiding outlets inclined at a predetermined angle and an exhaust mesh plate having vertical gas guiding outlets, which makes the high speed liquid flow and high speed gas flow sprayed out therefrom collide against each other sufficiently to form ultra-micro atomized particles with uniform and adjustable size. The ultra-micro atomized particles are sprayed out downwardly to the wafer surface under the acceleration and vertical orientation effects of an atomized particle guiding outlet to perform a reciprocating cleaning for the wafer. Other components such as an ultrasonic or megasonic generation unit, a gas shielding unit, a self-cleaning unit or a rotating unit can also be provided to perform the multifunction of the nozzle.

An air cap for a spray gun, in particular a paint spray gun, having at least one central opening, which is delimited by a mouth, and two horns, each having at least one inner and one outer horn air duct and one inner and one outer horn air opening. The spacing between the front end of the central opening and an axis which perpendicularly intersects the central axis of the central opening and runs through the centre of an inner horn air opening is between 0.6 mm and 2.6 mm. The spray pattern generated by the air cap has a longer core region and a steeper transition of the layer thickness between the external region and the core region, compared to conventional air caps leading to improvement in coating quality. A nozzle assembly and a spray gun, in particular a paint spray gun, can have an air cap having the above properties.

A spray head for directing water into a spray pattern that includes a casing configured to receive a supply of water and a plurality of nozzles disposed on the casing with each nozzle being configured to emit water in a stream away from the casing. The plurality of streams of water from the plurality of nozzles are configured to form a hyperboloidal shaped spray pattern.

A fluid control valve includes a body, a first diverter, a second diverter, and a first actuator. The body includes an inlet configured to receive a supply of fluid. The first diverter is movable in a radial direction within the body between a first radial position and a second radial position. The second diverter is movable in a longitudinal direction within the body between a first longitudinal position and a second longitudinal position. The first actuator is operatively coupled to the first diverter and to the second diverter. The first actuator is configured to simultaneously move the first diverter between the first and second radial positions and the second diverter between the first and second longitudinal positions.

An electrostatic spray apparatus includes an electrostatic spray gun having a first external surface and a second external surface. A first electrode is disposed on the first external surface and is configured to ionize a material and to generate a first electrical field between the first electrode and a grounded object. A second electrode is disposed on the second external surface of the apparatus and is configured to generate a second electric field between the second electrode and the grounded object.

A two part adhesive spray system is provided herein. This system provides numerous enhancements to the prior art including limiting overspray “fog,” saving on sprayed material because of a more efficient spray pattern, and providing a more efficient bond than that of the prior art. In particular, the present invention provides a spray pattern having both adhesive and activator. The activator is sprayed in a smaller spray area than the adhesive, which is sprayed on a larger area. As such, when sprayed on a substrate, the activator provides a rapid tack to hold a second adhered material to the substrate sufficient to hold it in place while the remainder of the adhesive dries and/or cures.

The present disclosure provides a system and method articulating and rotary spray system for fluids that includes a first drive for rotating a mast for different headings and a second drive for rotating a nozzle for different pitches at any time with or without rotation of the mast. The method and system uses a system of interacting gears that rotate a control rod in variable synchronization to control the nozzle pitch relative to the mast heading while the control rod orbits about a center of rotation of the rotating mast along a longitudinal axis.

The present invention provides spray devices for plumbing fixture fittings and unitarily formed components thereof having complex flow paths, made of multiple materials, and/or that are movable.

An alternator, such as for use in an electrostatic spray gun, comprises an electromagnetic alternator, a housing and an impeller. The electromagnetic alternator has a shaft. The electromagnetic alternator is disposed within the housing. The housing has an air aperture. The impeller is mounted to the shaft within the housing so as to be aligned with the air aperture. The impeller includes blades having curved leading and trailing edges. In one embodiment, each blade has a curvature so as to be perpendicular to the air aperture across an entire arc over which each impeller blade has a line of sight of the air aperture.

A fuel injector for a fuel spray nozzle of a gas turbine engine combustor includes an angular lip axially projecting into an upstream section of an annular passage to guide a fuel layer vortex to flow along a radially outer passage wall of the annular passage and to guide an air layer vortex to fill into and pass through an annular space between the fuel layer vortex and a radially-inner passage wall of the annular passage. The air layer vortex is free of mixing with the fuel layer vortex before the fuel layer vortex is discharged from the annular passage for fuel atomization.

This invention relates to thermal spray coatings and processes onto non-smooth surfaces. The coating and processes can coat non-smooth surfaces without substantial degradation of the underlying surface texture or profile of the non-smooth surfaces so as to sufficiently preserve the underlying surface texture or profile. The ability for coating fractional coverage to maintain the surface profile while maintaining wear resistance is unprecedented by conventional thermal spray processes

Electrospray ionization is today the most widely used ionization technique in chemical and bio-chemical analysis. Interfaced with a mass spectrometer it allows to investigate the molecular composition of liquid samples. With electrospray a large variety of chemical substances can be ionized. There is no limitation in mass which enables even the investigation of large non-covalent protein complexes. Its high ionization efficiency profoundly changed bio-molecular sciences because proteins can be identified and quantified on trace amounts in a high throughput fashion. This review article focusses mainly on the exploration of the underlying ionization mechanism. Some ionization characteristics are discussed which are related to this mechanism. Typical spectra of peptides, proteins and non-covalent complexes are shown and the quantitative character of spectra is highlighted. Finally the possibilities and limitations in measuring the association constant of bivalent non-covalent complexes are described.
