Applicant discloses a novel method of spray applying multiple courses of a rapid cure, two part polymer sealant to an aircraft surface. The method sometimes uses a two part polymer mix for use in the aircraft industry that is applied with pneumatic mix and spray gun. The two part cartridge is used in the mix and spray gun so the mix is applied immediately upon mixing, but the two components are kept separated unless the gun is applying the mix. The multiple courses cure to form a clear sealant that allows for inspection of cracks and corrosion beneath the sealant. It cures quickly so that the coated part may be further processed, for example in the assembly line during aircraft build. Applicant further discloses multiple spray gun systems for applying such a two-part polymer mix to aircraft parts.

A spray disk includes multiple nozzles at an outer perimeter of the spray disk, a center hole, and multiple partitions. The partitions are arranged around the center hole and have the center hole as an inner perimeter. Each partition includes an air inlet to receive compressed air, a liquid tank to store a liquid, and a corresponding nozzle from which to spray the liquid with the compressed air. The spray disk can be used in an automatic makeup machine.

Presently described are components of a spray application system. At least one component comprises a liquid repellent surface layer. The liquid repellent surface (e.g. layer) may comprise a porous layer and a lubricant impregnated into pores of the porous layer; a fluoropolymer; a fluorochemical material and an organic polymeric binder; or a fluorochemical material melt additive and a thermoplastic polymeric material component. The component is typically a liquid reservoir, a liquid reservoir liner, a lid for a liquid reservoir or liner, or a combination thereof. In some embodiments, the component comprises a thermoplastic polymeric material. In some favored embodiments, the component is a removable liquid reservoir or liner. In some favored embodiments, the component is a collapsible liquid reservoir or liner. The spray application system typically further comprises a gravity-fed spray gun. Also described are spray application systems, methods of using a spray application system, as well as methods of making a component of a spray application system wherein the component has a liquid repellent surface.

Silencing and separation in a cold-air, essential-oil, diffuser apparatus and method pass flow through a channel having comparatively high aspect ratios of length to thickness and width to thickness. Curved, tapered, non-parallel, and quasi random surfaces reduce probability and power of resonant frequencies. Offsetting flow through a channel is followed by impingement against an obstructing surface, redirection elsewhere within a drift (separation) chamber, and exiting through a smaller, and differently oriented exit port. Silencing is improved by changes of cross-sectional area creating high-pass and low pass acoustic filters, changes of direction, and absorption of acoustic energy in fluid-droplet-laden air.

The present application provides an atomizer structure and an atomizer having the same. The atomizer structure includes: a spray assembly including a first cavity; a bottle body configured for containing liquid and configured to be connectable to the spray assembly, the bottle body comprises a second cavity; a first connecting member communicating the first cavity and the second cavity and configured for guiding the liquid contained in the second cavity to enter the first cavity, when an air pressure in the first cavity is less than an air pressure in the second cavity; and a second connecting member selectively communicating the first cavity and the second cavity such that a quantity of remaining liquid in the first cavity can enter the second cavity, and configured for preventing liquid in the second cavity from flowing into the first cavity when the atomizer structure is tilted or inverted.

A method of texturing a wall or ceiling with non-acoustical joint compound by providing a collapsible bag having an opening at its top and is adapted to contain non-acoustical joint compound for forming a textured coating on the wall or ceiling and providing a spray nozzle having a low pressure input port, a joint compound suction port attached to the opening at the top of the collapsible bag, and an output port for spraying the non-acoustical joint compound. A low pressure stream of air from an air gun attached to the low pressure input port urges a small quantity of the non-acoustical joint compound to be sprayed out of the spray nozzle when the bottom of the collapsible disposable bag is raised above its top to either allow or force the joint compound to flow into the suction port and into the interior of the spray nozzle.
