Abstract: Systems and methods can determine a liquid flow in a spraying system. An amount of liquid that is output from the spraying system during a pump cycle is determined. A number of pump cycles that occur within a given amount of time are measured. The number of pump cycles are measured using an electronic speed controller (ESC). Additionally, the ESC indicates the number of pump cycles within a given amount of time within a threshold of precision. The amount of liquid flow in the spraying system is calculated based on the measured number of pump cycles and the determined amount of liquid that is output from the spraying system.

Abstract: A system for aerial spraying of agricultural crops or the like in which droplets of a controlled size are formed and discharged onto the ground instead of a fine spray. A system is provided for reducing pressure before delivery of the liquid to the discharge nozzles. The nozzles are directed so that the droplets are impelled by the air stream from the upper part of the nozzle structure and are then affected by the air stream and gravity in furtherance of the desire for droplets rather than micron-sized spray mists which too readily drift away from the desired area to be covered.

Abstract: A dispenser for discharging insects from a moving vehicle includes an insect retaining assembly and an insect acceleration chute. The chute receives air at several locations for accelerating the insects to the speed of the air passing the vehicle. The retaining assembly includes at least one surface for retaining the insects formed from a series of louvers which can be individually rotated on axles to discharge the insects. A metering valve is provided for delivering insects from the retaining assembly to the chute at a constant rate. A refrigeration apparatus is preferably provided for supplying cooled air to the retaining assembly to cool the insects. A method for discharging insects from such a dispenser includes the steps of depositing insects on each retaining surface and rotating the louvers individually at a constant rate to drop the insects from each surface at a constant rate.

Abstract: A rigid stabilizer bar is suspended from a quick-release cargo hook attachment point of the helicopter, and a yoke structure is releasably carried by the hook in fixed relation to the bar for suspending a load, opposite ends of the yoke having flexible lines connected to spaced apart locations on the load. Opposite ends of the stabilizer bar are connected by bungee cords to landing skid anchors for stabilizing the yoke. The load is oriented by yawing and rolling maneuvers of the helicopter. In an emergency, the yoke, together with the lines and the load, can be jettisoned from the vehicle by releasing the hook. The load can be a dispensing module for directing a fluidic medium such as crushed walnut shells in a high-pressure air blast from a nozzle that is located on a boom projecting from the module, onto an elevated workpiece such as an insulator of a tranmission line tower for cleaning the insulator. The cleaning module produces a stream of particulate. The helicopter can fly with the module suspended beside the insulator, the nozzle being aimed relative to the workpiece horizontally by yawing the helicopter and vertically by rolling the helicopter. The nozzle is also movable, and the boom can be raised and lowered by remote control for effective access in a variety of workpiece configurations. The module also generates foam for fighting fires.

Abstract: A centrifugal applicating device is disclosed which is hingedly connected below the product reservoir of an agricultural spray aircraft. The device includes an upper plate having a pair of feed openings and a pair of star wheel applicators rotatively carried by the upper plate below the feed openings. Each star wheel applicator includes a plurality of hollow nozzles in fluid communication with the feed openings to receive measured portions of granular agricultural materials. Each nozzle is formed with an enlarged, planar paddle on one side in position to be impinged by wind forces to rotate the star wheel applicators as the aircraft flies. A synchronizing mechanism interconnects the star wheel applicators to synchronize the speed of rotation and to assure a uniform spray pattern.
