The agricultural sprayer includes a base with two vertical guides fixed thereon and carriages mounted on and capable of traveling along said guides. A ducted fan is turnably mounted on axles between the carriages. The inner surface of the fan duct is equipped with nozzles connected to a liquid container. One of the carriages consists of two parts: the first and the second one, with the second part capable of moving relative to the first one. The first and the second parts of said carriage have a duct-swinging crank-rocker mechanism mounted thereon. Said mechanism is configured for setting the inclination angle of the fan duct and adjusting its oscillation amplitude.

A portable misting system includes a housing, an air pump carried by the housing to provide a flow of air, a water reservoir carried by the housing to hold a supply of water, and a water pump carried by the water reservoir to provide a flow of water droplets. An air/water nozzle assembly is carried by the housing and includes a nozzle body and a misting nozzle coupled to an output of the nozzle body. The nozzle body has an air input coupled to the air pump to receive the flow of air, and a water input coupled to the water pump to receive the flow of water droplets.

An apparatus, system, and method for providing a non-linear fluid stream into an environment for cooling purposes are disclosed. Such an apparatus includes a body portion and a nozzle, the nozzle being adapted to direct water into the environment. Such an apparatus may include a body portion having a flow channel defined therein for gas flow therethrough; and, a nozzle operatively disposed within the flow channel; said nozzle adapted to direct a liquid therefrom; wherein the channel and the nozzle are operatively disposed relative to each other so that a gas flowing through the channel and the liquid are combined into a fluid stream directed from the apparatus into the surrounding environment.

A fluid dispersal node is disclosed that includes one or more fluid outlets, an electromechanical valve, one or more hardware processors, hardware memory, a hardware wireless communication module, an antenna, and a fluid-tight, substantially radio frequency (RF) transparent enclosure. The valve is disposed in the node, and controls fluid flow to the outlets. The processors, in turn, control the valve. The wireless module receives instructions for operating the valve and forwards those instructions to one or more of the processors and the memory. The processors, memory, wireless module and antenna are disposed within the RF-transparent housing. In some embodiments, the antenna is disposed on a riser associated with the node outside the enclosure. In other embodiments, the antenna is disposed in a fluid line connected to the node.

The present invention relates to a dust suppression system for use in a container, and a misting apparatus therefor. In one form, the dust suppression system comprises at least one misting apparatus for contributing to the creation of a mist layer for preventing the escape of the dust from the container, the misting apparatus comprising a means for generating an airflow, and a means for producing a mist in the airflow so that the mist is carried by the airflow.

A lawn or garden ornament that utilizes either wind power or a flow of fluid to rotate various structural or spinning elements about multiple axes of rotation. When wind power is used, the spinning elements may rotate in unison about a vertical axis. When a fluid power is used, the spinning elements will additionally rotate independently of each other about a horizontal axis, and will turn in unison about the vertical axis. When fluid power is used, the fluid may additionally be used for watering of a garden as the design of the decorative lawn ornament promotes an even distribution of fluid to the surrounding support surface.

Spray nozzle systems and methods of use are described herein. The spray nozzle system may include a stationary tube, a rigid rotor, and a sub-medium supply source. The stationary tube may be in fluid communication with a pressurized air source. The substantially rigid rotor is in fluid communication with the pressurized air source. The substantially rigid rotor includes a substantially rigid conduit that is in fluid communication with the passages of the stationary tube and the rotor. A portion of the conduit is substantially arched such that an outlet of the conduit is offset a radial distance in a radial direction from the rotor axis. Pressurized air ejected from the outlet produces directional components of the pressurized air in the direction of rotation about the rotor axis; and during use, the pressurized air rotates the rotor and sucks sub-medium from the sub-medium supply source into the stationary tube passage.

A spray apparatus having built-in air regulation and a swivel connection to an air supply and uses thereof are described herein.

An air cleaning apparatus with a moist filter is disclosed. More particularly, the present invention relates to an air cleaning apparatus with a moist filter, being operated such that: water stored in a bottom reservoir tank flows upward in a centrifugal manner; water molecules are finely cleaved in a microfine state and injected through multiple injection holes in the same centrifugal manner to become moist; under such conditions, water flowing into a rotational column, to which a centrifugal force is applied, is filtered while circulating a cycle wherein external air inflowing through air input holes formed below a moist layer is adhered to water molecules in the moist layer and drops down, thereby enabling ultrafine dust as well as fine dust to be filtered with high efficiency and excellent economic advantage.
