TL;DR: In this paper, a shroud is provided which is disposed in encompassing relationship around the spray nozzle to which air is supplied at a controlled temperature and/or humidity which envelopes and becomes entrained in the spray forming a controlled localized atmosphere and achieving a controlled vaporization of solvent from the liquid droplets during the course of their travel from the nozzle to the surface of the substrate being coated.
Abstract: An apparatus and method for the spray application of solvent-thinned coating compositions whereby optimum coverage of a substrate with a liquid film is consistently achieved without incurring sagging, run-off or surface irregularities, such as orange peeling, in spite of wide fluctuations in the temperature and/or humidity of the surrounding atmospheric environment. In accordance with the invention, a shroud is provided which is disposed in encompassing relationship around the spray nozzle to which air is supplied at a controlled temperature and/or humidity which envelopes and becomes entrained in the spray forming a controlled localized atmosphere and achieving a controlled vaporization of solvent from the liquid droplets during the course of their travel from the nozzle to the surface of the substrate being coated.

TL;DR: In this article, a system for spray cooling large quantities of heated water has a plurality of spray forming means each consisting of a pluralityof associated nozzles connected by piping to pumps, each of the associated noizles having an outlet constructed and arranged to discharge the water in a coherent stream which impinges upon the stream ejected by each other associated nozzle in a common zone beyond the nozzle with a force which breaks the streams into a spray of drops having a resultant trajectory away from the nozzle into a receiver.

The water may be aerated before discharge from the nozzles, this being effectively accomplished by means of air inlets to a venturi passage in each nozzle.
