A sprayer system including a wand, a rotary arm, a motor, a housing, a support, and a controller or control panel. The wand has a nozzle at one end. The rotary arm rotates around a first axle, and is connected at a distal end through a bearing to an opposite end of the wand. The housing covers or encloses a part of the wand, the rotary arm, and a rotatable ring through which the wand passes. The motor drives rotation of the rotary arm. The support mechanically supports the housing. The controller/control panel controls rotation of the rotary arm. The wand, the rotary arm and the ring are configured so that rotation of the rotary arm causes the nozzle to move in a circular, elliptical and/or oval pattern. Methods of making and using the sprayer system and software for controlling the system are also disclosed.

A spray arm system for cleaning articles in the wash chamber of a dishwasher appliance is provided. The spray arm system includes an elongated spray arm and an orbital spray arm positioned near opposite, bottom corners of the wash chamber. The elongated spray arm pivots about one corner within a horizontal plane and the orbital spray arm rotates about a central axis near the opposite corner. The elongated spray arm may be motor-driven, the orbital spray arm may be fluid-powered, and the spray arms may be operated independently or at the same time.

A slit opening of a slit nozzle extends unidirectionally in a longitudinal direction from near the center of a circular substrate to near an outer edge of the substrate, and has a length in the longitudinal direction equal to or smaller than a radius of the substrate. When the slit nozzle discharges chemical onto the substrate, a rotary holder rotates the substrate and the slit nozzle relatively to each other about the center of the substrate. Accordingly, the chemical from the slit nozzle all adheres to a surface of the substrate to form an excellent liquid column and a chemical film on an almost entire surface of the substrate along the outer edge of the circular substrate. This yields satisfactory coating of the substrate with the chemical while waste chemical is suppressed.

A descaling device having a device housing, a shaft, a shaft bearing, a nozzle head and a medium coupling, wherein the shaft bearing is arranged in the device housing and the shaft is mounted in the device housing by the shaft bearing for carrying out a rotary movement, wherein the shaft and the nozzle head are detachably connected to one another in a non-destructive manner, wherein the medium coupling has a medium connection for supply of a medium, wherein the shaft has a shaft cavity for conducting the medium supplied at the medium connection to the nozzle head. The descaling device has an improved maintainability and reliability due to the descaling device having a motor, and due to the motor being arranged on the shaft in the device housing between the nozzle head and the medium coupling in order to generate the rotary movement of the shaft.

An effective implementation is shown for a height adjustment system for a plurality of spray guns used in a line striper.

The inventive concept provides a substrate treating apparatus. According to an embodiment, the substrate treating apparatus may include a liquid supply unit that supplies a treatment liquid onto a to-be-treated surface of the substrate, and the liquid supply unit may include a support shaft spaced apart from the spin chuck by a specific distance, and extending to have a specific length in a direction that is perpendicular to a ground surface, a nozzle support, one end of which is coupled to an upper end of the support shaft, and extending to have a specific length in a direction that is parallel to the ground surface, a nozzle installed at an opposite end of the nozzle support and that supplies the treatment liquid to the substrate, and a motion sensor that detects any one or more of a deflection, a distortion, and a vibration of the liquid supply unit.

Various embodiments of an apparatus, methods, systems and computer program products described herein are directed to an agricultural treatment system and method of operation. The agricultural treatment system uses a spraying apparatus for spraying fluid at agricultural objects. The spraying apparatus is configured with a spraying head assembly that includes a moveable spraying head with one or more spraying tips a first motor assembly having a first motor interconnected with the spraying head assembly, wherein the one or more spraying tips pivot and rotate about an axis via a rotation of the first motor to emit a first fluid of the one or more fluids at the agricultural objects.

An applicator machine and a process for heating and coating a section of pipeline. The applicator machine includes a frame configured to rotate about a section of pipeline to be heated and coated, rotating means operable to rotate the frame, and coating material applicators induction coils and radiant heaters mounted on the frame and rotatable therewith. The induction coil is configured to heat a section of pipeline adjacent to the induction coil to a coating material application temperature. The radiant heaters are configured to heat factory-applied coatings. Each coating material applicator sprays coating material through an aperture in a respective induction coil. The applicator includes an enclosure configured to surround a section of pipeline and provision for evacuating and collecting waste coating material. The coating material applicator may be configured to spray powder coating material, such as fusion bonded epoxy powder material and/or chemically modified polypropylene powder material.

The invention relates to a device and a method for descaling a workpiece, which is in motion in relation to the device in a movement direction (X). The device (10) comprises a rotor head (14), which is rotatable about an axis of rotation (R), which is inclined diagonally at an angle () with respect to an orthogonal on a surface (20) of the workpiece (12). Furthermore, the device comprises multiple jet nozzles (16), which are attached on the rotor head (14), wherein a liquid (18), in particular water, is dispensable onto the workpiece (12) at an angle of attack () inclined to the surface (20) of the workpiece (12) from the jet nozzles (16). The jet nozzles (16) are fixedly attached on the rotor head (14) such that during rotation of the rotor head (14) about its axis of rotation (R), the spraying direction (S) of the liquid (18) dispensed from the jet nozzles (16), with respect to a projection in a plane parallel to the surface (20) of the workpiece (12), is aligned opposing, i.e., at a spraying angle () of approximately 180, the movement direction (X) of the workpiece (12).

Provided are a system and process for remanufacturing a waste cylinder assembly of an aircraft piston engine. The spraying apparatus includes a first power mechanism, a spray gun assembly and a second power mechanism. The first power mechanism drives the cylinder assembly to move in a horizontal direction and a vertical direction. The second power mechanism drives the spray gun assembly to rotate around a center of the blind hole and ensures that prepared coatings can be evenly distributed along an inner wall of the blind hole. A nozzle end of the spray gun extends into the blind hole, and the spray gun is adjustable relative to the center of the blind hole. A spraying distance is not fixed so as to change the spraying distance. Powder can be fully melted.
