A fluid dispenser apparatus includes a fluid dispenser having plurality of nozzles aligned in a first longitudinal direction. A dispenser shield is positioned relative to the plurality of nozzles, the dispenser shield configured to form an aperture aligned in the first longitudinal direction with the plurality of nozzles. The plurality of nozzles are configured to dispense fluid towards a substrate. The dispenser shield is further positioned such that fluid dispensed from a first subset of the plurality of nozzles passes through the aperture while fluid dispensed from a second subset of the plurality nozzles is captured by the dispenser shield.

A handheld sprayer (10) includes a fluid module (12′) mounted to a drive module (14′) at a static connection (16) and a dynamic connection (18′). The static connection (16) supportably attached the fluid module (12′) to the drive module (14). The dynamic connection (18′) connects a drive (84) of the drive module (14′) to a pump (24) of the fluid module (12) such that the drive (84) can power the pump (24) by the dynamic connection (18). The fluid contacting components of the handheld sprayer (10′) are in the fluid module (12′). The fluid module (12′) can be mounted to and dismounted from the drive module (14′) by a sliding motion.

A spray apparatus that includes a stand, a motor secured to the stand, a spray applicator secured to the stand, and a rotatable disc secured to the stand relatively above the spray applicator such that the rotatable disc is positioned within a spray field of the spray applicator. The rotatable disc is coupled to the motor such that the rotatable disc is configured to rotate in response to activation of the motor. The rotatable disc is configured to receive an overspray from the spray field to generate a spray pattern from the spray applicator. The apparatus includes a scraper positioned in fixed engagement with the rotatable disc, where the scraper is configured to remove accumulated overspray from the rotatable disc.

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.

A roll to roll fabrication apparatus includes an injection plate for injecting a chemical treatment liquid on a film transferred from a supplying roll to a collecting roll; and liquid blocking rolls disposed between the supplying roll and the collecting roll, and configured to prevent the chemical treatment liquid injected from the injection plate from being introduced to another process region.

Disclosed herein are various embodiments of a system and method for operating a surface pressure washer with a wand component. The method may include the steps of cleaning a first surface through a first fluid path, where the first fluid path includes a pump, a pressure regulating valve, a diversion block, and a spray gun, while spray nozzles are not discharging fluid to a second surface, actuating a valve connected to the diversion block, thereby reducing the pressure available to the first fluid path and creating a second fluid path, where the second fluid path includes the pump, the pressure regulating valve, the diversion block and the spray nozzles, where the spray nozzles are configured to rotate above the second surface when the second fluid path is open, and cleaning a second surface underneath the pressure washer system through the second fluid path.

A coating apparatus for coating a component with a coating agent includes an applicator for delivering at least one coating agent jet of the coating agent to the component. The coating apparatus includes an intercepting device which in an active position intercepts the at least one coating agent jet between the applicator and the component so that the at least one coating agent jet does not strike the component.
