A nozzle including a plurality of moveable nozzles configured to transition between a first state in which streams produced by the nozzles combine to form a collective stream, or the appearance of a collective stream, and at least one second state in which the nozzles produce separate respective streams; and a drive mechanism configured to transition the nozzles between the first and second states.

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

A portable spray cleaning system with a device for sanitizing the interior surface of residential trash cans. The device includes adjustable arms, a plurality of spray nozzles, and rubber clamps. On one end, the device may also include a port for connecting to a water supply via a hose. Once the hose is connected, water can then be sprayed out through the spray nozzles. The pressure created by the water flow enables the device to rotate while water is being sprayed. There may also be a compartment for inserting a disinfectant that mixes in with the water. The device is collapsible for easy storage and packaging. It is known that trash receptacles often become very dirty and contaminated after repeated use.

Various embodiments of an apparatus, methods, systems and computer program products described herein are directed to an agricultural observation and treatment system and method of operation. The agricultural treatment system uses a treatment unit for emitting a laser at agricultural objects. The treatment unit is configured with a treatment head assembly that includes a moveable treatment head with one or more laser emitting tips. A first and second motor assembly are operated by the treatment unit to control the movement of the treatment head. The first motor assembly includes a first motor rotatable in a first rotational axis. A first linkage assembly is connected to the first motor and the treatment head assembly. The first linkage assembly is rotatable by the first motor. The second linkage assembly is rotatable by the second motor.

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.

An apparatus includes a moving device movable along the surface of an object, and a rotary nozzle device. A rotary nozzle means comprise a plurality of jet nozzles. Two sets of the rotary nozzle means are arranged in parallel in a direction orthogonal to the moving direction of the moving device, are configured such that a left rotary nozzle means and a right rotary nozzle means perform a rotary motion in association with each other by a rotary transmission means. The jet nozzle of the left rotary nozzle means and the jet nozzle of the right rotary nozzle means are arranged so as to be out of phase with each other.

An assembly for delivering a fluid includes a fluid dispenser connected to a fluid supply conduit. The fluid dispenser includes a fluid outlet positioned along a length of the fluid dispenser. The fluid outlet is configured to deliver the fluid from the fluid supply conduit at a flow rate that varies along the length of the fluid dispenser.

A cleaning device includes: a treatment container; a workpiece carrier arranged in the treatment container and configured to hold at least one workpiece; at least one nozzle configured to discharge a cleaning jet directed onto the workpiece carrier and mounted such that the at least one nozzle is moveable on a circulation track about the workpiece carrier and is pivotable about a pivoting axis extending parallel to an axis of rotation of the workpiece carrier; a pivoting device configured to pivot the at least one nozzle; and a controller configured to control a circulating movement of the at least one nozzle on the circulation track and a pivoting movement of the at least one nozzle, such that a specified point on a surface of the workpiece is impacted repeatedly by the cleaning jet at a respectively different angle, within a specified timeframe.
