Abstract: A rotary disc atomizer adapted to generate relatively precisely controlled, uniformly sized spray droplets whether mounted in a vertical position or in significantly tilted positions. The atomizer includes a power driven rotary disc having a tapered fluid dispensing surface, a liquid supply whirl chamber in coaxial relation to the disc, and a liquid feed arrangement adapted to tangentially feed liquid into the whirl chamber so that it is rapidly moved in a relatively uniform thin sheet about the chamber and then exits in an annular uniform flow centrally onto the dispensing surface of the disc. The centrifical forces of the swirling feed liquid permit the atomizer to be mounted in substantially tilted positions without effecting the uniformity of the spray output or droplet size.

Abstract: A fluid transfer system including a cap member having a first fluid transfer member therein and being removably mountable on a second fluid transfer member. Cooperating lugs and slots formed by the cap member and second member lock the two members together when the cap is placed on the second member and rotated relative thereto. A resilient annular gasket is disposed between the second member and cap member and surrounds the liquid passageway therethrough to prevent leakage. The second member and cap members form an annular space on one side of the outer peripheral portion of the gasket, and an annular bead presses against the other side of the outer peripheral portion of the gasket so that the bead bends that portion of the gasket into the annular space to effect a liquid-tight seal on both sides of the gasket.

Abstract: An automatic power reduction circuit having a single silicon controlled rectifier in one leg of a bridge rectifier which is gated off when a capacitor reaches a predetermined voltage level so as to switch automatically the bridge output from a full-wave rectifier to a half-wave rectifier. An auxiliary silicon controlled rectifier is also provided to facilitate the quick discharge of the capacitor so as to reset the circuit to its initial state, thereby allowing fast, repeated operations and preventing malfunctioning upon a loss of power.

Abstract: A quick-disconnect nozzle connection for a spraying tip and a nozzle body. The spraying tip is defined by a cylindrical inlet stem at one end of the tip, an interior fluid passage communicating from the inlet of the cylindrical stem through the tip to an orifice, at least one arcuate section extending radially outwardly from the cylindrical surface of the stem, and a recess formed in each arcuate section.

Abstract: This invention relates to a solenoid valve primarily intended for association with agricultural equipment and provides a balanced valve for controlling the spraying of fluids wherein the armature is separated from the fluid and which requires minimum electrical power for actuation because of a balanced seat design so that the force acting on the valve stem due to fluid pressure is zero. Consequently, only a relatively small external force is required to move the stem and a small coil can be utilized to operate the valve.

Abstract: An unloader type valve for spray guns supplied from pumps to limit operating pressures of the pump when the spray gun is stopped. The valve utilizes an adjustable spring to select pressure forces for opening the valve and a variable flow passage from the valve to an outlet when the valve is open, the allowing matching of the valve to the precise operating pressures and flow rates in spray gun and pumping system installations.
