Abstract: Various methods and apparatuses may be used to spray sloped surfaces, such as by using a nozzle (1). The method of the invention for spraying a fluid on turf having sloped surfaces may include spraying the fluid using a flat fan spray angle between 110 and 130 degrees and an inclination angle between 4.5 and 9.0 degrees. In some implementations, spraying the fluid may include spraying the fluid using a flat fan spray angle of approximately 120 or 127 degrees. In some implementations, spraying the fluid may include spraying the fluid using an inclination angle of approximately 4.5 degrees. In some implementations, spraying the fluid may include spraying the fluid using an inclination angle of approximately 6.5 degrees. In some implementations, spraying the fluid may include spraying the fluid using an inclination angle of approximately 9.0 degrees. In some implementations, the inclination angle may include a backward facing angle.

Abstract: Embodiments of the invention provide a bayonet system for attaching a nozzle body to a nozzle turret. The bayonet system can be rotated with respect to a spray nozzle. A seal can be positioned between the spray nozzle and the nozzle turret. The seal can be compressed by moving the bayonet system without exerting any substantial torsion force on the seal. The bayonet system can help prevent unintentional disengagement of the spray nozzle.

Abstract: An anti-vibration mechanism for lock nuts is disclosed. The invention is made up of a cylindrical tube having a hex nut midway along its length and external threads on each side of the hex. One of the threaded ends is adapted to have an internally threaded, knurled collar screwed onto it. To ensure this collar does not vibrate loose, a groove is machined into the threaded zone on which the knurled collar is to be screwed and an elastomeric O-ring is fitted into this groove. When the knurled sleeve is tightened, there is an increased frictional engagement between the O-ring and the threaded inner diameter of the knurled collar preventing loosening of the collar.

Abstract: Nozzle attached to the boom of agricultural sprayers each include an improved air eduction system and discharge slot eliminating the need to change the angle of the boom and nozzle to ensure a comprehensive spray pattern irrespective of boom height and improved penetration of the material sprayed into and under the crop canopy.

Abstract: A spray nozzle has a pre-chamber and a mixing region. A first inlet defines a first fluid flow path for admittance of a first fluid to the pre-chamber. A second inlet defines a second fluid flow path which is crossed by the first fluid flow path for admittance of a second fluid to the pre-chamber. A wall is positioned between the pre-chamber and the mixing region and has an aperture therethrough coaxial with the first fluid flow path. Fluid can pass from the mixing region out of the spray nozzle through an outlet, the outlet not lying on the first and second fluid flow paths. A first fluid entering through the first inlet mixes with a second fluid entering through the second inlet in the mixing region prior to the mixed first and second fluids passing out through the outlet.
