Abstract: A high-pressure rotary nozzle includes a magnetic coupling for the purposes of driving a rotor body within the nozzle housing. The nozzle housing defines an internal chamber, and a propulsion ring is retained within the housing such that a liquid introduced into the propulsion ring causes the propulsion ring to rotate and passes into the chamber. The rotor body is pivotally supported within the chamber and is operably coupled to the propulsion ring such that the rotor body moves along with the propulsion ring. The rotor body rotates about the housing, such that the liquid exits the chamber in a rotating jet.

Abstract: A gun mount for a spray gun includes a rigid bracket that is installed on a rigid vertical support such as a gun mover. The bracket securely mounts the guns so as to reduce vibration and swaying during a spraying operation, even when the guns are being vertically moved by an oscillator. A position label or other suitable indicia is provided on the bracket so that the gun mount position can be recorded and thereby accurately repeated during subsequent installations. The bracket in one embodiment includes a series of vertical and horizontal mounting holes that permit a gun body to be installed at a desired vertical and horizontal orientation. A gun blow off arrangement is also provided for mounting associated pairs of air nozzles in position to blow powder from gun exterior surfaces. The associated pairs of air nozzles are mounted on a common bracket that can be selectively and slideably positioned on a channel support.

Abstract: The present invention includes a unique irrigation sprinkler system with a unique sprinkler head design; a unique method of defining the planted area to be served by the sprinkler head; a unique method for determining when that planted area needs to be watered; a unique way of providing even coverage throughout the planted area when being watered; the ability to use one sprinkler head to individually water multiple, non-overlapping planted areas; a unique way of addressing multiple sprinkler heads in the same sprinkler system; and a unique method for remotely determining the integrity of the sprinkler system.

Abstract: A mechanism that steers a high energy density output(s) in a shaking motion other than a rotating motion that when translated across a surface evenly affects the surface. One application can be used as an end effector. A pivot on the mechanism induces an angular motion that eliminates the tops and bottoms of the pattern produced by the shaking motion. As a waterjet stripping mechanism which may be an end effector, a nozzle or output manifold with one or more orifices or outputs is attached to a non-rotating tube eccentrically mounted within a rotating tube that shakes the nozzle or output manifold so as to direct the stream of water to the target in a skewed circular pattern.

Abstract: An assembly for spraying a fluid along an orbital path generally consisting of a support member, an elongated member universally connected to the support member intermediate the ends thereof, a drive shaft having a crank arm mounted thereon for rotational movement therewith, a universal connection between the crank arm and the end of the elongated member and an opposite end of the elongated member having a fluid passageway provided with an inlet connectable to a fluid supply line and at least one outlet.

Abstract: A rotary drive sprinkler having a multiplicity of nozzles which can be changed at any time. The nozzle assembly can have a cylindrical housing having a plurality of nozzles to rotate against a cylindrical housing having at least one stream outlet opening. A nozzle assembly can have a cylindrical cavity at its outer portion receiving a flexible nozzle strip for directing flow from a nozzle housing. A nozzle sleeve, or ring, having a plurality of exit nozzles around the outside of the nozzle assembly can be rotated about an inner housing.

Abstract: A spray cleaner (10) is provided for rotatingly cleaning an interior of a vessel or the like. The spray cleaner has a main body (12) and a rotating spray body (14). The main body is at a proximal end of the spray cleaner, and the rotating spray body is at a distal end of the spray cleaner. An internal flow conduit (22) in the main body of the rotating spray body communicates a fluid inlet in the main body to a plurality of spray nozzles (18) in at least one spray head which is a part of the rotating spray body. A drive train (30) for rotating the spray body is positioned in the main body, such that the flow conduit passes around the drive train in an annular passage coaxial with the drive train, providing cooling thereto. A vaned rotor (26) in the flow conduit is connected to an input shaft (28) of the drive train, which transfers torque to an output drive system (42) that is fixedly connected to the rotating spray body.

Abstract: A sprinkler includes a riser having a lower end for receiving a pressurized fluid and a nozzle that is mounted at an upper end of the riser for rotation about an axis. A turbine is mounted for rotation inside the riser. A drive mechanism connects the turbine to the nozzle so that rotation of the turbine by the pressurized fluid rotates the nozzle. The sprinkler includes mechanisms for preventing over-spinning of the turbine when the pressurized fluid is air or a mixture of air and water. Damage to the turbine drive shaft or its bearings due to over-spinning of the turbine is thereby avoided. In one version of the sprinkler, the over-spinning prevention mechanism applies a brake force to the turbine. In another version of the sprinkler, the over-spinning prevention mechanism re-directs air or a mixture of water and air around the turbine.

Abstract: A reversing gear drive system is provided in an irrigation sprinkler for reversibly shifting the direction of rotation of a sprinkler spray head for back and forth part-circle rotation between adjustably set end limits, to sweep an outwardly projected stream of irrigation water through a predetermined arcuate pattern to irrigate a surrounding terrain area and associated vegetation. The reversing gear drive system includes a gear carrier having first and second output gears driven rotatably in opposite directions. A shift mechanism is provided for shifting the gear carrier between forward-drive and reverse-drive positions with the first and second output gears alternately engaged with a ring gear for rotatably driving the spray head in opposite directions. The shift mechanism includes a shift lever and a reverse trip spring for engaging arcuately spaced limit stops mounted for rotation with the spray head.

Abstract: A device for controlling the flow of water spray nozzle, comprises a valve member (E) normally biassed to a seated, closed position; an actuator (D) carried by a rotatable actuator shaft (C) and operable on the valve member (E) to displace the latter, against its bias, to an unseated, open position; a wheel (I) adapted, in use, to make frictional contact with the conveying run (K) of a loaded conveyor belt and to be rotated about an axis co-axial with that of the actuator shaft (C) by linear movement of the loaded belt, and a coupling means to couple wheel rotation to the actuator (D), and comprising firstly a disc or annulus (A) of electrically conducting material also rotatable about an axis co-axial with that of the wheel (I) and secondly a plurality of magnets (G) also carried by the actuator shaft (C) rotatable co-axially with the wheel (I) and disc or annulus (A) and located with air-gap spacing from the disc or annulus, with means to restrict the rotation of the actuator shaft (C) through a prescribed

Abstract: A spinning wash nozzle assembly having a fluid brake pump within the rotating spinner housing. The fluid pump has a sump which is also within the rotating spinner housing such that centrifical forces acting on the fluid tend to separate the heavier fluid from any air within the sump. As a result, only the fluid is drawn into the pump as opposed to fluid and air. This avoids undesirable effects on the pump from air being drawn therein.
