A battery powered fluid sprayer includes a battery mounted to a vertically extending wall of the fluid sprayer. The battery powers an electric motor to power a pump to pump fluid to a spray gun for spraying. The battery is disposed within a battery chamber enclosed by a door. The battery is suspended above a base of the battery chamber to isolate battery from any fluid that may enter the chamber.

An arrangement for automated painting of an object includes a paint robot, a cover and a cover blocking member. The paint robot defines an axis joint about which a first portion rotates relative to a second portion. The cover covers at least a portion of the paint robot. The cover blocking member is in the form of a strip brush including a plurality of bristles. The strip brush is carried by the paint robot and is positioned between the paint robot and the cover.

A paint shield 10 for receipt on top of a doorway floor and between a first door jam and a second door jam. The paint shield includes a flat base sheet having one end with a first cutout center on one end and dimensioned to match a cross section of the bottom of the first door jam and engage the sides of the first door jam to prevent wet paint from spilling onto the floor next to the door jam. The paint shield also includes a sliding top sheet received on top of the flat base sheet. The top sheet has one end having as second cutout with a second cutout center on one end and dimensioned to match a cross second of the bottom of the second door jam.

Aerosols can be created by filament stretching and breaking of Newtonian and non-Newtonian fluids by applying a strain to and stretching the fluid. The fluid is stretched along a strain pathway and forms a fluid filament between diverging surfaces. The stretched fluid filament breaks into droplets that can be harvested to form a mist or aerosol. The aerosol creation systems can include one or more pairs of counter-rotating rollers that are positioned adjacent to each other that stretch the fluid or a pair of pistons that move toward and away from each other to stretch the fluid. Some aerosol creation systems can include multiple pairs of counter-rotating rollers that are positioned in a circular, oval, or linear pattern. The aerosol creation system with multiple pairs of counter-rotating rollers can generate mist is one or more directions and can be positioned between two concentric rings or linearly, among other configurations.

A method of generating a building assembly that includes spraying a coating material onto a plurality of pieces of substrate disposed on a first assembly face. The spraying includes spraying the coating material onto the plurality of pieces of substrate via a sprayer configured to apply the coating material to a target surface via a nozzle coupled with a mobile storage container storing the coating material, the coating material impregnating voids of the substrate. The method also includes allowing the coating material impregnating the voids to dry and harden and become rigid to generate the building assembly.

A shroud for a sprinkler head having a series of removable tabs to allow for configuring a shield-to-shield water distribution from the sprinkler head. The shield has removeable tabs of which allow for water to be sprayed past the shield. The shroud is utilized to configure the distribution of water from a sprinkler head so as, for example, to limit water distribution on unintended or undesired areas. Embodiments of the shroud can be configured to attach by a clip to a sprinkler head, by engagement with a weight threadingly engaged with the sprinkler head, by friction engagement with the sprinkler head, or by alternate attachment. The shroud can be configured in different embodiments to attach to a specific sprinkler head in the industry or configured to attach to different varieties of sprinkler head.

A spray application system and a method of its operation are provided for applying a spray treatment onto a surface of an airframe of an aircraft. The spray application system includes a set of multiple modular hood units that are combinable to form a combined enclosure that defines a shared interior volume. Each modular hood unit of the set includes one or more enclosure walls. At least two airframe-interfacing edges of each modular hood unit define a portion of a spray treatment region of the airframe. At least one inter-unit-interfacing edge of each modular hood unit is configured to interface with another inter-unit-interfacing edge of a neighboring modular hood unit of the set to form at least a portion of the combined enclosure. A spray access port is defined within an enclosure wall of each modular hood unit.

A spray containment system for a wing-body section includes a forward module, a center module, and an aft module. The forward module has a forward closeout panel configured to engage a forward end of a fuselage center section of the wing-body section. The center module has opposing module side panels each configured to engage a wing lower surface of a wing of the wing-body section. The aft module has an aft closeout panel configured to engage an aft end of the fuselage center section. The forward module and the aft module are independently movable and are configured to be assembled around the wing-body section to define an internal environment that is sealed from an external environment for containing contaminants including at least one of vapors, overspray, and liquids generated during application of one or more of coatings, sealants, and adhesives to localized areas of the wing-body section.
