A dispensing system for a rotary dispensing machine includes a tank, a fill tube, and a piston that moves along the fill tube and defines an air chamber and a fluid chamber within the tank. The tank is rotatable relative to the fill tube. A fluid is dispensed from the fluid chamber of the tank through at least one outlet formed in the tank.

A robotic fountain is proposed. The robotic fountain includes: a water supply pipe rotating while passing through upper and lower surfaces of a main body of the fountain; a fastening part formed between the lower surface of the main body and a lower end of the water supply pipe; a first motor configured to rotate the water supply pipe; a support part formed between the upper surface of the main body and an upper end of the water supply pipe; a bypass body fastened to the top of the water supply pipe; a through hole formed through one side of a lower surface of a rotary body, the rotary body fastened to an upper surface of the bypass body; an intermediate pipe configured to rotate inside the rotary body; a second motor for rotating the intermediate pipe; and a nozzle formed at the center of the intermediate pipe.

A wastewater spray distribution apparatus is operative to distribute wastewater produced by a sewage treatment system (10) onto a ground level (22) through operation of sprayers (118, 260). The exemplary sprayers include a manifold (142, 262) that includes outlet nozzles (158, 264) that can be readily removed and replaced. The exemplary manifold further includes interior areas bounded by surfaces that slope continuously downward from the outlet nozzles to the manifold inlet to assure the draining of water therefrom. Each of the nozzles include a base (140) which includes a liquid tight jacket (208). The jacket isolates components which facilitate movement of a rotatable hub (154), from water passing through the sprayer and other contaminants. A brake is provided in each nozzle and includes a liquid lubricant in the jacket that operates to limit rotational movement produced by the thrust of water passing from the outlet nozzles to assure that the sprayer operates at the appropriate rotational speed.

A coating device for applying a coating agent to the surface of a workpiece. The coating device includes a frame having a workpiece receptacle, a coating agent source, a compressed air source, and a rotary unit which is rotatable in relation to the frame. The rotary unit has a pump and a plurality of spray units, the pump on the suction side being connected to the coating agent source by a fluid-conducting rotary joint connection, and on the pressure side being connected to the spray units. The rotary unit has a pneumatic valve device, and the spray units have in each case one compressed air controlled valve for controlling the delivery of coating agent. The valve on the inlet side is connected to the compressed air source by a fluid-conducting rotary feedthrough and on the exhaust air side is connected to the compressed air controlled valves of the spray units.

A lawn maintenance device that is calibrated in the field by a user through a mobile software app to irrigate and/or fertigate one or more arbitrary geometrical areas defined by the user. The device includes a motorized rotary drive mechanism for controlling the rotational angle of a pivotable nozzle and a flow control valve for controlling water jet throw distance. At least one container is integrated into the device for dispensing fertilizer, herbicide and other such concentrated lawn or garden solutions. The device communicates with and is controlled by a web server which dynamically computes a watering path and triggers the device to commence irrigation over the computed path based on prevailing local environmental conditions and/or user settings.

A wastewater spray distribution apparatus is operative to distribute wastewater produced by a sewage treatment system (10) onto a ground level (22) through operation of sprayers (118, 260). The exemplary sprayers include a manifold (142, 262) that includes outlet nozzles (158, 264) that can be readily removed and replaced. The exemplary manifold further includes interior areas bounded by surfaces that slope continuously downward from the outlet nozzles to the manifold inlet to assure the draining of water therefrom. Each of the nozzles include a base (140) which includes brake (207). A brake is provided in each nozzle and is adjustable to provide brake force to limit rotational movement produced by the thrust of water passing from the outlet nozzles to assure that the sprayer operates at the appropriate rotational speed. Alternative arrangements include manifolds including fixed or adjustable flaps and radially outwardly adjustable arms to adjust rotational properties.

A cleaning apparatus includes a connection part rotatably mounted to a rotatable member. The connection part is in the form of a disc 36 of plastics material, with a central cavity with four radial passages extending therefrom leading to nozzles for steam to pass therethrough for cleaning purposes. In use the disc is rotated at a required speed to, for instance, clean a conveyor.

A dispensing system for a rotary dispensing machine includes a tank, a fill tube, and a piston that moves along the fill tube and defines an air chamber and a fluid chamber within the tank. The tank is rotatable relative to the fill tube. A fluid is dispensed from the fluid chamber of the tank through at least one outlet formed in the tank.

A bearing assembly suitable for a fluid delivery system such as a hydraulic water cannon, including for a first pipe that is moveable relative to a second pipe, the assembly comprising a main body adapted to be connected to an end of the first pipe, an annular centre swivel adapted to be connected to an end of the second pipe, the centre swivel including an annular, axially extending boss extending away from the main body, with the opposed radially extending face extending radially outwardly from said boss, and a bearing end cap adapted to engage around the second pipe and be fastened to the main body securing there between said centre swivel. The bearing assembly is adapted to operate at water pressures greater than 10 bar.

A rotary tank assembly is provided for a liner. The liner is structured to apply a compound to a plurality of container closures. The rotary tank assembly includes a compound tank, a fill tube structured to fill the tank with a volume of the compound to a desired level, a sensor assembly adapted to measure the level of the compound within the compound tank, and a rotary union assembly structured to pivotably couple the fill tube and the sensor assembly to the compound tank. The sensor assembly only requires one single probe.
