Abstract: A method and system are provided for injecting a color component into a plural component coating dispensing system. Base, cure and color components are pumped from respective containers at metered volume. The color component, which is preferably a low-viscosity automotive paint is injected into the either the base or cure stream at a point immediately prior to mixing all components in a dispensing device for dispensing the resulting colored fluid mixture onto a surface to be coated. The mixture may be dispensed by pouring or spraying onto the surface. The method and system are particularly useful for mixing and dispensing colored polyurethane or polyurea coatings, such as for spray-on truck bed liners.

Abstract: A battery operated, handheld fluid dispenser comprises a supply container having a body portion and a narrow neck extending upwardly therefrom. A pump and discharge unit is mounted on the upper end of the neck and comprises a pump diaphragm and pump chamber for pumping liquid from the container to a discharge nozzle. A battery powered pump drive unit is mounted on the container and comprises an electric motor having an output shaft coupled with the pump diaphragm through a cam and cam follower arrangement to displace the diaphragm through a pump stroke when the motor is energized. The cam is rotatably driven by the motor, and the cam follower is attached to the diaphragm, whereby rotation of said cam axially displaces the diaphragm, and the cam and cam follower have interengaging dual cam faces for balancing lateral forces therebetween during rotation of said cam relative to said cam follower.

Abstract: Mobile towers of an irrigation system have drive wheel assemblies that propel the towers along the ground. At least certain of the wheel assemblies may comprise dual wheels that share a common axis of rotation but are separately driven by their own drive motor. By driving the two separate wheels in unison but with their own individual drive shafts, increased ground-engaging surface area can be obtained without a consequential increase in load for any one motor.

Abstract: A mixing capsule for a two-component mixture comprises a preferably cylindrical container part. An axially displaceable piston is guided within the container part. An opening is provided on the front face of the piston and leads into a liquid receptacle with a burstable wall or membrane. The membrane closes the opening in the non-activated condition of the capsule. The hollow between the front faces of the container part and the piston constitutes a mixing chamber. The activation part can be displaced by means of activation pin that closes the discharge nozzle in the non-activated condition. In the activated condition of the capsule the activation part is to all intents and purposes completely accommodated within the liquid receptacle.

Abstract: The present technique provides a system and method for improving atomization in a spray coating device by internally mixing and breaking up a desired coating fluid prior to atomization. In one embodiment, a flow barrier is disposed in the spray coating device downstream of an internal fluid valve and upstream of a fluid exit. The flow barrier may have a plurality of passages configured to direct fluid streams to create a fluid swirling and rotating motion around a central axis of a central flow path to facilitate fluid mixing and breakup. The plurality of passages may direct the fluid streams toward a surface, and may be angled substantially toward one another or diverging from one another. Embodiments of the spray coating device may further include an atomization mechanism adapted to facilitate formation of a spray of the fluid flowing from the fluid exit. The resulting spray coating has refined characteristics, such as reduced mottling.

Abstract: A flow-through joint in an irrigation machine between the main pipeline section and a swing span, such as a corner span, permits a limited amount of generally linear displacement of the swing span within the joint for speed control or other purposes. A turret that rotates freely on the upright outlet port of the main pipeline section has a pair of coupling assemblies on opposite sides of the upright pivot axis through the outlet port, one of such coupling assemblies having a ball joint and the other being provided with relatively displaceable components. The arms of a connecting yoke on the inner end of the swing span are coupled with the ball joint on the one hand and the displaceable components on the other so as to provide the necessary swinging and pivoting motions while at the same time allowing displacing movement as necessary for control purposes.
