An applicator and method of use is disclosed for applying coatings and paints to various surfaces. As shown, the sprayer may have an undercarriage frame that supports three-wheels. All three wheels may run parallel with the first wheels and second wheels attached to the sprayer frame via an undercarriage with the third wheel positioned behind and between both the first and second wheels on a separate arm or frame. The width of the sprayer booms may be adjusted. The undercarriage may be folded entirely or only a portion therein. The arm of the third wheel may be folded or telescope, as required by a particular application. A handle, which may be adjustable, may be positioned between the sprayer frame and the undercarriage. Use of the applicator according to the method discussed herein reduces operator fall exposure and increases application efficiency.

The system includes a robot multi-jet system having a spray section, a drier section, and a catalyst section. The drier section includes a warm air blower, the catalyst section includes a photocatalyst tank, and the spray section includes a plurality of jet extensions. A first jet extension connected to the photocatalyst tank sprays a uniform layer of a photocatalyst through a first set of jets, and a second jet extension that is mechanically connected to the drier section and in fluid communication with the warm air blower is configured to spray a gas onto an inner surface of the glass tube with a second set of jets. Both the drier section and the catalyst section are mounted on wheels to move the system on the inner surface of the glass tube. A motor is electrically connected to a battery mounted within the robot and mounted to the wheels.

An agricultural sprayer includes a computing system configured to receive a first input associated with a target application rate at which agricultural fluid is to be dispensed onto the field. Moreover, the computing system is configured to receive a second input associated with a turn being made or to be made by the sprayer. Additionally, the computing system is configured to determine a maximum ground speed for the turn at which a selected nozzle dispenses the agricultural fluid onto the field at the target application rate based on the received first and second inputs. Furthermore, when the turn is being made, the computing system is configured to control an operation of the sprayer such that the ground speed of the sprayer is at or below the determined maximum ground speed.

A fountain apparatus (100) includes a submersible pump (1), a water supply pipe (2) including one end connected to a discharge port (13b) of the submersible pump (1), a rotating mechanism (5) including a rotating shaft (51) and a water jet nozzle (50) configured to jet water supplied through the water supply pipe (2), and a support mechanism (4) provided at the other end of the water supply pipe (2) and configured to rotatably support the rotating mechanism (5) via the rotating shaft (51). The water jet nozzle (50) includes a first jet nozzle (53) configured to jet the water in a jetting direction having a propulsive force component in a circumferential direction of the rotating shaft (51).

A flexible misting umbrella apparatus for keeping a user cool in hot environments includes a handle having a handle sidewall, a handle top side, and a handle bottom side defining a handle cavity. A water reservoir is coupled within the handle cavity. A pump is coupled within the handle. A trigger is coupled to the handle and is in operational communication with the pump. A flexible tubing extends from the handle top side and is in fluid communication with the pump. The flexible tubing is malleable under the force of a user's hand and otherwise maintains its shape. An umbrella frame is coupled to the flexible tubing. A plurality of nozzles is coupled to the umbrella frame and is in fluid communication with the flexible tubing to release mist when the trigger activates the pump. An umbrella canopy is coupled to the umbrella frame.

The autonomous paint spraying machine is an autonomous mobile system for making paint markings on surfaces. The autonomous paint spraying machine includes a chassis having longitudinally opposed first and second edges, where the first edge has a linear contour and the second edge has an arcuate contour. A linear track is mounted on the chassis adjacent the first edge, and an arcuate track is mounted on the chassis adjacent the second edge. A paint receptacle is mounted on an upper surface of the chassis, and a plurality of driven wheels are mounted on a lower surface of the chassis. A controller is configured for controlling actuation and orientation of the plurality of driven wheels. First and second spray nozzles each receive paint from the paint receptacle. The first spray nozzle is slidably mounted on the linear track, and the second spray nozzle is slidably mounted on the arcuate track.

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.

An apparatus and a method for increasing the movement speed of the rail vehicle while carrying out measures for controlling weeds on track systems. A rail vehicle equipped with an apparatus for increasing the movement speed of the rail vehicle while carrying out measures for controlling weeds on track systems.

A spray pyrolysis system and method are described for manufacture of mixed metal oxide compositions, e.g., mixed metal oxide catalyst compositions having utility for gas processing applications such as hydrogenation, dehydrogenation, reduction, and oxidation. Mixed metal oxide automotive exhaust catalyst compositions produced by such system and method achieve a substantial reduction in temperatures required for removal of automotive exhaust pollutant species, as compared to catalyst produced by conventional batch precipitation techniques. The spray pyrolysis system and method enable catalytic metal(s) to be integrally incorporated in the mixed metal oxide composition, thereby obviating a separate catalytic metal impregnation operation.

A work machine can include a frame; a spray system couple to the frame and including a spray bar having a plurality of nozzles; a pressure sensor to detect a pressure of a liquid within the spray bar; and a controller to determine whether the detected pressure of the liquid within the spray bar has exceeded a pre-determined pressure threshold.
