A modular apparatus for coating glass articles with a chemical compound includes a coating hood section (10a) including a series of interconnected walls (12) defining an interior chamber (18, 20a, 20b) having an inlet (32) and an outlet (44), a blower (24) positioned at least partially in the interior chamber (18, 20a, 20b) to carry air from the inlet (32) towards the outlet (44); and a connector (50) for connecting the coating hood section (10a) to an identical coating hood section (10b). The connector (50) for connecting being defined on at least one of the interconnected walls (12) of the coating hood section (10a).

An overspray protection device has a housing which is engageable directly to a paint spray gun or to a conduit extending from the paint gun. An interior cavity of the housing provides a pathway for a stream of paint emitted by a spray nozzle to a surface being painted, which is protected from wind by a sidewall defining the shape of the housing and the interior cavity.

A fluid dispenser, comprising a dispenser faceplate having at least one ejection port and a dispenser guard. The dispenser guard has at least one opening configured to allow fluid exiting from the ejection port to flow through and at least one drainage structure. The dispenser guard is spaced from the ejection port with a gap small enough to attract the fluid accumulated around the ejection port to flow into the drainage structure.

A liquid-emitting device for gravity-based irrigation systems includes a support structure that defines a first axis and has a nozzle for generating an irrigation jet coaxial with the first axis, a tubular body below the support structure, and a baffle plate facing the nozzle and rotatably mounted in the tubular body to rotate about a second axis. The nozzle is stationary and the second axis is free to rotate about the first axis with a precessional motion. Guides are removably coupled to the tubular body to interact with the baffle plate and prevent the precessional motion while allowing the rotational motion about the second axis. A diverting member may be removably positioned downstream from the nozzle to distribute the liquid over an area of the soil. An arrangement of a nutating liquid-emitting device in combination with an anti-nutating adaptation kit is also disclosed.

A method of controlling application of at least one material to a substrate is provided. The method includes configuring at least one array having a plurality of micro-applicators such that a subset of the micro-applicators is individually addressable to apply the at least one material to the substrate. Individually addressing the subset of micro-applicators provides control of a pattern width of a coating applied to a substrate, control of a flow rate of the material applied to the substrate, control of an angle of application of the material to the substrate, control of which and how many materials are applied to the substrate, and combinations thereof.

An application system for applying a substance over a predetermined surface includes a frame movable over the predetermined surface, a pressurized carrier source, a vessel containing the substance. The system further includes a first conduit for conveying the substance from the vessel to at least one nozzle and a second conduit for conveying a pressurized carrier from the pressurized carrier source to the at least one nozzle for applying a mixture of the pressurized carrier and the substance over the predetermined surface. The system further includes a cover laterally surrounding the at least one nozzle for minimizing overspray of the mixture, the frame carrying the pressurized carrier source, the vessel, the first conduit, the second conduit, and the cover.

An ultrasonic atomization material applicator includes a material applicator with at least one transducer and an array plate with an array of micro-applicators. Each of the micro-applicators has a material inlet, a reservoir, and a micro-applicator plate with a plurality of apertures. At least one supply line is in communication with the micro-applicators and configured to supply at least one material to each of the micro-applicators. The at least one ultrasonic transducer is mechanically coupled to the at least one array of micro-applicators and configured to vibrate the at least one array of micro-applicators such that atomized droplets of the at least one material are ejected from each of the micro-applicators. A movement device configured to cyclically move the at least one array of micro-applicators back and forth about at least one axis of the at least one array of micro-applicators can be included.
