Abstract: A flexible tube sprinkler comprises a connector at one end, a nozzle at the opposite end, and a flexible tube between the connector and nozzle permitting free movement of the nozzle by the weight thereof and by the reaction forces of the water discharged therefrom. Enclosing the connector end of the flexible tube is a rigid sleeve having an axial bore of larger diameter than the external diameter of the connector end of the flexible tube such that there is a clearance between the inner face of the rigid sleeve and the outer face of the connector end of the flexible tube permitting the rigid sleeve to be impacted by the flexible tube during the operation of the sprinkler to control the movements of the flexible tube and thereby the distribution of the water discharged from the nozzle.

Abstract: A nebulizer device for producing an aerosol spray via a flow of gas at varying oxygen concentrations is disclosed. The nebulizer device comprises a body defining an initial nebulization chamber, a subsequent baffling chamber and a venturi formed therebetween. Air intake ports are disposed on the body adjacent the nebulization chamber for providing the nebulization chamber with air in predetermined quantities. Regulating means are disposed about the nebulization chamber for regulating the flow of the air through the intake ports. An aerosol system for producing an aerosol of fine particles of liquid is located in the nebulization chamber upstream of the venturi such that the flow of the aerosol spray through the venturi encourages the atmospheric fluid to enter the device through the intake ports thereby diluting the aerosol. The venturi is located downstream of the intake ports and increases the flow rate of the atmospheric fluid through the intake ports.

The pipe ends may be carried by tractors, one of which will have a pump for forcing the spray medium along the pipe and that tractor, or the other, will have a winch with a drum on which the pipe is wound. The winch is controlled to maintain the pipe tensioned and clear of the ground despite variations in the spacing between tractors. A fixed structure could replace one of the tractors.

Abstract: Apparatus for converting a liquid into an atomized mist and, in one form of the invention discharging the mist to the atmosphere, in another form of the invention discharging the mist into an air stream for spraying the mist onto a receiving surface, and in still another form of the invention discharging the mist in a selected pattern of spray onto a receiving surface without the use of an air stream. The liquid is converted into an atomized mist by a mechanical operation wherein the liquid is fed through orifices in a spray head and a blade is moved rapidly over the orifices so as to shear particles of liquid from the main stream and discharge them therefrom as a fine mist. The airstream can be generated by a fan that is part of the apparatus and is driven by an electrical motor that actuates the blade, or the airstream can be generated by a second source of energy located remotely of the apparatus.

A shroud is provided to confine excessive adhesive, and a screen or field of vacuum-applying holes are positioned within the shroud and around the nozzles to suck excess adhesive back into a reservoir. A heater is used to keep the plastics soft and flowing.

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.

Abstract: Spray nozzles are aimed at openings in the side of capture chambers. Fluid is pumped directly from sumps within the capture chambers through the spray nozzles and into the capture chamber openings. Vegetation passing between the nozzles and the capture chambers is sprayed, and any fluid not intercepted by vegetation is returned to the sumps after entering the capture chamber openings. The fluid level in each sump is regulated by a float valve which interrupts a flow of fluid fed by gravity from a supply tank.
