A self-cleaning, automated apparatus with a filter for fluids includes a nozzle unit assembly that has two nozzle tubes, one inside of another. Each of the tubes has a respective pattern of one or more slots or holes. As the tubes rotate, one with respect to the other, part of the pattern of the one coincides at times with part of the pattern of the other, resulting in a jet of fluid directed toward a filter to remove debris from the filter. The filter is rotated so the jet can reach all parts to be cleaned. The respective patterns of the two nozzle tubes may be an approximation of a helix and/or an approximation of a line.

A material applicator for controlling application of at least one material on a substrate includes a housing and an array plate with an applicator array positioned within the housing. The applicator array has a plurality of micro-applicators and each of the plurality of micro-applicators has an ultrasonic transducer, a material inlet, a reservoir, and a micro-applicator plate with a plurality of apertures. The applicator plate is in mechanical communication with the ultrasonic transducer such that at least one material is ejected through the plurality of apertures as atomized droplets when the ultrasonic transducer vibrates the micro-applicator plate.

There is provided systems and methods for effective cleaning and drying of vehicles of different shapes and sizes. In an example, a conveyor system may move a vehicle along a path, and a bridge assembly supported above a vehicle is moveable along the length thereof. At least one trolley assembly is moveable in a direction transverse to the movement of the bridge assembly. At least one cleaning arm assembly delivers cleaning fluid to or for brushing the surface of a vehicle. The cleaning arm assembly is moveable in association with movement of the vehicle to position the cleaning arm assembly adjacent at least a portion of the front, sides and rear of the vehicle as it moves along the path. A variable impact or patterning spray arm or drying system is also provided.

A cleaning device is for a vehicle. The cleaning device has at least one cleaning nozzle configured to apply a cleaning fluid to a surface to be cleaned of at least one sensor, a fluid supply unit, in particular a fluid valve or a pump, configured to selectively provide the cleaning fluid to the cleaning nozzle, and an actuator for generating a cleaning movement of the cleaning nozzle. It is provided in the cleaning device that the cleaning device has a switching unit for controlling the actuator, such that the cleaning movement can be generated independently of the fluid supply unit.

Method of producing prills includes providing a hollow body rotatable about a first axis, the body having a wall rotationally symmetrical around the first axis forming an interior space, the wall including nozzles; providing a second body disposed in the hollow body such that a gap exists between the hollow body and the second body; supplying liquid to the gap; generating jets of liquid from the nozzles radially outward by driving the rotational motion of the hollow body and/or second body around the first axis of rotation using a rotary drive unit; applying a reciprocal pressure excitation on the jets of liquid by moving the hollow body and/or second body along the first axis; and decoupling the rotations of the one of the hollow body and second body and a reciprocating drive-unit.
