Abstract: A system for controlling the operation of a moving irrigation system lengthens the period of the on-and-off cycle specified by the speed timer to drive the pivot arm assembly. This reduces the frequency of the on-and-off cycles and thereby reduces wear and tear on the drive components. To modify the cycle period, a processor determines a modified on-time and a modified off-time having the same ratio of on-time to off-time as the speed timer to maintain the same average speed for the pivot arm assembly. The processor then controls operation of the pivot arm assembly to move in an on-and-off manner using the modified on-time and modified off-time.

Abstract: An agricultural sprayer spray head is adapted for being mounted to a spray boom together with a plurality of like, equally spaced spray heads. Each spray head includes a body containing a flow control member mounted for rotation about an axis and including a fluid control passage arrangement located for effecting an intermittent connection between a fluid inlet leading to, and an outlet leading from the body as the control member is oscillated or rotated by a powered motor so as to effect a pulsing flow through said control passage arrangement. The powered motor operates at a speed controlled by various input parameters including vehicle speed and field and crop conditions so as to maintain a desired spray application rate.

Abstract: The invention concerns a two-part spray application system and method for applying a two-part spray on an object. First and second pumps have outlets, with the pressure at each outlet monitored by pressure transducers. During the spraying process for each object, the pressure at the outlet of each pump must exceed a minimum threshold pressure at least once, or a fault condition is indicated. Such fault conditions may indicate a leak or disconnect in a hose downstream of the pumps.

Abstract: A device carried on a moving vehicle for creating marking lines, which are a plurality of elements and are made of a highly viscous marking material, on a surface that is to be marked. The device includes a housing formed by walls and a discharge slot formed in at least one of the walls of the housing and extending transversely to a direction of movement of the vehicle, the discharge slot being limited in extent by a front discharge slot edge and a rear discharge slot edge, seen in the direction of movement of the vehicle. A pressurized material supply line leads to an interior of the housing. A rotatable hollow cylinder formed of a jacket is located in the interior of the housing and is arranged to rotate with the movement of the vehicle carrying the device. The cylinder is provided with a plurality of passages through the jacket, which, depending on a rotary position of the cylinder, establish a connection between the pressurized material supply line and the discharge slot.

Abstract: A retort is described for use with paperboard containers (48) to reduce moisture absorption during processing of foodstuffs therein. The improvement includes using solid cone spray nozzles (50) with spray angles in the range of about 100 degrees to about 115 degrees. In one embodiment, the distance (D?) between the nozzles and the container is in the range of about 70 mm to about 200 mm. In another embodiment, the flow rate if each nozzle (50) is reduced relative to known systems, while the total vessel flow rate is kept the same as per cubic meter load. Further, an overpressure may be added to the vessel via compressed air. In accordance with other aspects, an Impact reduction is used which relates nozzle flow rate, pressure, distance, etc. with moisture absorption in paperboard containers.

Abstract: A device for the cleaning and maintenance of the cooling fins of a heat exchanger of an air conditioner unit includes a pistol-grip water nozzle having a water inlet providing a water pressure of between about 40 to about 80 pounds per square inch (about 300 cm Hg), the nozzle having a threaded outlet.

Abstract: A crop spraying apparatus includes a self-powered blower mounted on the rear rack of an ATV, with an air manifold extending behind the blower. Left and right spray nozzle assemblies are mounted on respective branches of the manifold, each actuatable either individually or together, so that the spray pattern may be directed to either side or both sides of the ATV.

From the valves the solution is fed to injectors, each injector secured in one of the spray nozzles. The blast of air exiting each nozzle breaks up the injected solution into a fine mist that is carried by the air stream to the crops.
