Title: Apparatus and method for dispersing a liquid treating agent

Abstract: A liquid treating agent is dispersed by introducing it into a stream of air under pressure, attenuating the air-entrained liquid on the inside diameter of a conduit so the liquid will subdivide into unsuspended droplets when released through an opening, and releasing the attenuated liquid through a dispersing conduit preferably of smaller diameter so the droplets will be impelled forward, falling on the substrate.
