A water intake (82) is coupled to the nozzle manifold (42) and to a hydraulic drive (80) having a mechanical power take-off member (96) that is operably coupled to the nozzle carriage (16) for moving the nozzle carriage.

An additive manufacturing machine may include an energy beam system configured to emit an energy beam utilized in an additive manufacturing process, and one or more optical elements utilized by, or defining a portion of, the energy beam system and/or an imaging system of the additive manufacturing machine. The imaging system may be configured to monitor one or more operating parameters of the additive manufacturing process. The additive manufacturing machine may include a light source configured to emit an assessment beam that follows an optical path incident upon the one or more optical elements, and one or more light sensors configured to detect a reflected beam comprising at least a portion of the assessment beam reflected and/or transmitted by at least one of the one or more optical elements. The additive manufacturing machine may include a control system configured to determine, based at least in part on assessment data comprising data from the one or more light sensors, whether the one or more optical elements exhibit an optical anomaly.

The machine (1) for washing cages and accessories comprises a washing booth (2) for washing animal cages (G) by means of a washing liquid, a first tank (8) and a second tank (9) intended for collecting and recycling the washing liquid according to the acid/basic value of the liquid itself, the tanks (8,9) being positioned below the washing booth (2) and in fluidic communication with the latter. The machine (1) comprises deflection means (17) of the washing liquid positioned between the washing booth (2) and the tanks (8,9) and intended to deflect the washing liquid alternately towards the first tank (8) or the second tank (9).

An aircraft windshield wiper system includes a wiper arm, a wiper blade coupled to a first end of the wiper arm, and an output shaft coupled to a second end of the wiper arm. The wiper blade includes a fluid dispensing system including nozzles, a fluid control unit, fluid lines, fluid source, and a user interface. The wiper blade with the fluid dispensing system is configured to dispense a variety of fluids directly from the wiper blade onto the windshield of an aircraft.

The present disclosure discloses a cleaning robot, including a housing, a receiving tank, and a liquid storage tank. The housing is provided with a first groove and a second groove spaced apart from each other. The receiving tank is located in the first groove and configured to receive dirt. The liquid storage tank is located in the second groove and configured to store a cleaning liquid. In the cleaning robot of the present disclosure, the receiving tank and the liquid storage tank are arranged separately and spaced apart from each other, such that the volume of the liquid storage tank is increased, thereby allowing a larger area to be cleaned with a tank of water stored.

A method for manufacturing a water-absorbent resin includes a cleaning step of cleaning the inside of a heat exchanger that is connected to a vessel holding an aqueous gel-like polymer as a precursor of the water-absorbent resin and is configured to cool a gas containing the polymer generated in the vessel. The heat exchanger, and includes: a plurality of pipes that have an elongated path through which the gas passes, in which the gas is cooled due to heat dissipation during passage through the paths; a chamber that is arranged above the plurality of pipes and is in communication with openings at upper ends of the plurality of pipes; and a cleaner that sprays a cleaning liquid in the chamber. The cleaning step includes at least cleaning the inside of the chamber by spraying the cleaning liquid from the cleaner in the chamber.

A brushless car wash system includes a wash unit that washes upper surfaces of the vehicle. The height of the wash unit is adjusted based on the contour of the upper surfaces of the vehicle. Adjusting the height of the wash unit results in increased wash performance of the brushless car wash system.

A nozzle assembly for use in liquid-dispensing system, the nozzle assembly including: a body configured to receive a pipe; and the pipe, an end of the pipe being mounted on the body. The pipe includes multiple lumens correspondingly terminated in multiple orifices such that a liquid is escapable from each lumen through the corresponding orifice and is thereby dispensable from the nozzle assembly. The pipe has a first flow-capacity to supply a first volume of the liquid at a first flow-rate and at a first pressure. Each orifice and corresponding lumen has a second flow-capacity to supply a second volume of the liquid at a second flow-rate and at a second pressure.

The speed, effectiveness, and convenience with which pallets and other objects are cleaned can be increased by using a pressure power-washing apparatus described. The apparatus includes at least one pressure-washer that pumps liquid from a tank into rotary arms within a cleaning chamber, causing the rotation of the arms as the arms eject streams of the liquid pumped under a high pressure from angled nozzles. Conveyors carry an object in need of cleaning into the cleaning chamber, first exposing the object to the streams of the liquid, and then to a drying chamber. Guide rails positioned on the platform guide the object during cleaning, with the shape of one of the guide rails causing the object to fall off following the drying to remove excess liquid left on the object.

A toilet seat cleaning device removably connected to at least a portion of a toilet, the toilet seat cleaning device including a plurality of seat cleaning units removably connected to at least a portion of a seat of the toilet to cleanse the seat using a liquid in response to each of the plurality of seat cleaning units moving from a rear portion of the seat in a first position to at least partially toward a front portion of the seat in a second position, a liquid storing container connected to the plurality of seat cleaning units to store the liquid therein, and a sensor connected to the plurality of seat cleaning units to send a command to the plurality of seat cleaning units to move the plurality of seat cleaning units in response to a departure of a user from the seat.
