A system and method treating a horizontal surface of uncured concrete. The surface treatment system comprises a boom mounted to a vehicle body and an implement mounted to a mounting plated disposed at the working end of the boom. The implement comprises a texturing brush configured to engage a horizontal surface of the uncured concrete to apply a texture pattern thereto. The implement also comprises a first and second spray bars. The first spray bar is configured to apply a first chemical to the bristles of the texturing brush when in an engaged position. The second spray bar is configured to concurrently apply a second chemical to the textured surface of uncured concrete while the texturing brush is applying the texture pattern to the horizontal surface of the uncured concrete.

The invention relates to a modular system for weed control for a rail vehicle. The modular system has a control unit for producing control signals for controlling valves and mixers in a separate herbicide and mixing module and for producing a second set of control signals for controlling valves of a nozzle rod. The herbicide and mixing module has a container for holding different herbicides and electrical connection elements for connections to the control unit. Furthermore, a nozzle rod is present, which is fitted with a nozzle set, in order to spray herbicides of the herbicide and mixing module. In addition, a camera module is present, which produces a weed signal in response to the detection of a weed, in order to control the spraying of the herbicides. The camera module is at such a distance from the nozzle rod that, despite high speed, there is sufficient time to provide the herbicide at the nozzles.

A cleaning process of wafer polishing pad, the process includes providing a wafer polishing pad, performing a planarization process with the wafer polishing pad, leaving a residue on the wafer polishing pad after the planarization process, and performing a cleaning step with a cleaning nozzle to remove the residue, the cleaning nozzle comprises at least one Y-shaped pipe, one end of which is a water outlet, and the other two ends are respectively a water inlet and an air inlet, wherein a cleaning liquid flows from the water inlet to the water outlet, and a pressurized gas flows in from the air inlet.

A system for spraying plants comprises a location-determining receiver for estimating a position of a sprayer with respect to one or more rows of plants. A distance sensor is arranged to measure a distance between a nozzle assembly and a plant row segment. A guidance module is adapted to align the nozzle assembly with a target path between the rows of plants, such as a centered path between the rows, or offset between the rows of the plants. A first nozzle is targeted toward a first zone with respect to the plant row segment based on a first spray pattern of the first nozzle. A second nozzle is targeted toward a second zone with respect to the plant row segment based on a second spray pattern of the second nozzle. A nozzle selection module for selecting automatically a first nozzle or a second nozzle based on maximum coverage of a target zone around the plant segment based on the first zone, the second zone, and the measured distance.

A liquid spraying system having an elongated liquid supply boom and a plurality of spray nozzle assemblies. The spray nozzle assemblies have a compact design with a nozzle body having a liquid inlet and a first spray nozzle carrying liquid outlet section on opposite upper and lower sides, second and third spray nozzle carrying liquid outlet sections disposed in transverse relation to the supply boom; and first and second check valve supporting sections disposed parallel to the liquid supply boom. A first of check valves is operable for controlling liquid flow from the supply boom to one or both of the second and third spray nozzles, and a second check valve is operable for controlling liquid flow from said liquid inlet to said first spray nozzle. The illustrated check valves are operable in response to the pressure of the supply liquid.

A sump pump irrigation assembly for reducing water erosion from a sump pump outlet includes a plurality of fluid fittings. A respective one of the fluid fittings is fluidly coupled to an outlet of a sump pump to receive water from the outlet. A supply pipe is fluidly coupled to the fluid fitting that is fluidly coupled to the outlet to receive the water from the fluid fitting. A plurality of drainage pipes is each of the drainage pipes is in fluid communication with the supply pipe to receive the water from the supply pipe. Each of the drainage pipes has a plurality of holes therein to release the water outwardly therefrom. A plurality of cleanout fittings is each fluidly coupled between a respective pair of the drainage pipes. Each of the cleanout fittings has an access port to facilitate debris to be removed from the cleanout fittings.

A shower head insert comprises at least two water nozzle cartridges, each having at least two nozzles configured to produce water jets that impact to atomise the liquid producing droplets of water, and an injection moulded water distribution system to supply liquid to the at least two water nozzle cartridges. The water distribution system comprises at least two sockets for receiving the water nozzle cartridges, a central water inlet conduit in liquid communication with the first socket, and a narrow bore conduit providing high pressure liquid communication between the first and second sockets. The narrow bore conduit is configured to allow removal of conduit inner mould needles from the conduit after injection moulding through an open end of the sockets and in one embodiment comprises an upwardly depending section and downwardly depending sections. A shower head or shower head assembly comprising the shower head insert, and a water nozzle cartridge for the shower head insert, are also provided.

A system for an agricultural vehicle can include a nozzle assembly positioned along a boom assembly. A position sensor can be associated with the boom assembly. A field sensor can be associated with the nozzle assembly. A computing system can be operably coupled with the nozzle assembly, the position sensor, and the field sensor. The computing system can be configured to detect a target within a field based on data from the field sensor, determine a boom deflection model based on data from the position sensor, and activate the nozzle assembly to apply an agricultural product to the target at a first flow rate based on the boom deflection model. The first flow rate is varied from a nominal flow rate when the boom assembly is deflected.
