A system for cleaning an interior of a boiler may include a lance tube operatively coupled to one or more positioning devices, and a cleaning tip coupled to one or more insertion devices. The lance tube may include a distal end from which pressurized water flows out of the lance tube into the interior of the boiler. The one or more positioning devices may be configured for moving the distal end of the lance tube in an X direction and/or a Y direction relative to a wall of the boiler to direct the flow of water from the distal end of the lance tube. The one or more insertion devices may be configured for moving the cleaning tip between a retracted position and an extended position.

The invention relates to a connector head (12) comprising an interior space (40), a tank connector (13) which is in fluid communication with the interior space (40) and which can be fluidly connected to a valve apparatus (10) mounted on the tank (9) for filling or emptying the tank (9), a product port (14) in fluid communication with the interior space (40) and a discharge port (33) in fluid communication with the interior space (40). To allow a tank to be filled and emptied under improved hygienic conditions, it is proposed that the connector head (12) comprises a first valve (29), with which first valve (29) the product port (14) can be shut off from the interior space (40), a second valve (34), with which second valve (34) the discharge port (33) can be shut off from the interior space (40), and a cleaning device (38) adapted and arranged to clean the interior space (40) and the tank connector (13). The invention also relates to a valve block.

A powdering system, having a working configuration and a cleaning configuration and including a powder reservoir, including a supply chamber receiving powder; a sprayer, including a powder applicator, and a cleaning inlet, fluidly connected to the supply chamber such that, in the cleaning configuration, a cleaning air supply source can be connected to the cleaning inlet so as to circulate cleaning air in the supply chamber, wherein the powder reservoir includes a discharge opening, arranged through a wall of the supply chamber and opening into the supply chamber, and a movable plug, which is movable between a closing position, in the working configuration, and an open position, in the cleaning configuration, such that the circulation of cleaning air causes residual powder to be discharged through the discharge opening.

Provided are a robot for performing droplet jetting, and a droplet jetting control method for a robot. The robot for performing droplet jetting comprises a control system, a mechanical motion structure, a droplet jetting system, and an aerodynamic balance system. The control system implements motion control and droplet jetting control. The mechanical motion structure is a multi-degree-of-freedom mechanical structure and is used to implement a multi-degree-of-freedom motion function. The droplet jetting system is installed at the mechanical motion structure. The aerodynamic balance control system controls, according to a change in an air pressure of a nozzle, air pressures inside and outside of the nozzle to attain a balance so as to ensure a stable jetting, thereby preventing jetting of an excessive amount or an insufficient amount of droplets. The robot for performing droplet jetting can realize freer fabrication of products having planar and curved surfaces without any dead angles by performing omni-directional micro-droplet jetting.

A fountain system is provided. The fountain system includes a fountain nozzle that includes a body configured to telescope during extension and retraction and a nozzle outlet coupled an end of the body. The fountain system also includes an extension system configured to actuate the extension and retraction of the body. The fountain system also includes an actuation system configured to activate discharge of a liquid, such as water, from the nozzle outlet. The extension system and the actuation system are discrete systems.

A system and method have been shown for the effective implementation of a height and rotational adjustment system for one or more spray guns for use in a line striper.

A system and method for the application of friction-modifying coatings to roadways, walkways, pathways and other areas subject to vehicular, human or animal traffic, the system and method comprising the controlled, simultaneous application of binder and filler to a surface of a substrate, using a mobile device which passes over the substrate as the binder and filler are being applied. The system includes a frame coupled to a vehicle. A binder applicator is mounted on the frame and includes an array of spray nozzles coupled to a resin container. An air knife is mounted on the frame and coupled to an air compressor for generating an air curtain. An aggregate dispenser bar including at least one aggregate dispenser is coupled to an aggregate bin and mounted on the frame for dispensing aggregate.

A tank system includes a primary arm and a secondary arm mounted on a trolley. Each arm is configured to independently rotate 340 to 360 degrees in horizontal planes. The primary arm includes a pivot frame for adjusting the vertical position of the secondary arm by pivoting the primary arm in a vertical plane. At least one nozzle and a submersible pump are mounted to the secondary arm. The tank system is mounted within a tank or other enclosure by securing the trolley to a track system within the tank or other enclosure. The trolley is configured to move along the track system within the tank or other enclosure. The tank system may pump a fluid from the tank in a pumping configuration, mix the fluid within the tank in a mixing configuration, and/or clean the tank in a cleaning configuration.
