Abstract: An improved controlled droplet applicator for applying fluid in droplet form to a target area. The applicator includes a rotary atomizer for generating fluid droplets of ideal size and density. The improvement includes a fan for rotating with the atomizer and for causing the fluid droplets to move toward the target area.

Abstract: A recirculating sprayer assembly directs treatment spray streams against a collector means having its lower end extending through an enlarged opening in a reservoir means. A screen means extends between the collector means and the adjoining edge or edges of the reservoir means. Alternatively, a fibrous mat collector is folded over with its free ends positioned within a tray member. A plurality of ports pass the recovered liquid retrieved by the mat into the reservoir as well as limit the admission of foreign particles into the reservoir. At the upper end of the tray, lip surfaces flare outwardly away from the collection plane of the mat to collect loose drops falling from the mat and return them to the tray for passage into the reservoir. In a still further embodiment, a folded-over fibrous mat collector fits into an upper slot opening of a trough-shaped reservoir having upper wall side openings extending generally outwardly from the collection plane of the mat.

Abstract: A recirculating sprayer adapted for mounting on a vehicle is improved for use at increased travel speed and for operation in higher wind conditions by angling the solid spray streams forwardly or rearwardly from a direction transverse to the travel direction. The sprays are employed in criss-cross, opposite pairs, with the spray stream patterns of adjacent pairs of spray nozzles abutting or overlapping one another for full coverage of all upstanding weeds or crops in an area traversed by the sprayer. A series of collector mats or panels may be arranged transverse to the travel direction, with sprays trained thereon for contacting each weed twice in its upstanding position once by each spray of a pair; the weeds may also be contacted once more as they are bent forward to pass beneath the panels and a reservoir thereunder. The collector may also be arranged in panels parallel to the travel direction, for increased ease in negotiating sloping terrain.
