The invention relates to a refillable device (1) for spraying an active substance, comprising a reservoir (2) containing at least one active substance, said device being equipped with a piezoelectric spraying mechanism (6). The device is attached to or in the collar of an animal. The invention also relates to the use of said device for spraying an active substance in a controlled manner from a distance in a desired direction. Said device can be used multi-directionally independently of the movements of the animal.

A brushless car wash system includes a variable width. The width of the brushless car wash system is adjusted according to a width of a vehicle being washed. By adjusting the width of the brushless car wash system, wash performance of the brushless car wash system is increased.

A gypsum slurry modifier device is provided for use with a gypsum mixer outlet boot having at least one tubular outlet leg, and includes a support bracket mountable to the outlet boot; at least one clamp member associated with the support bracket and constructed and arranged for engaging the at least one tubular outlet leg of the outlet boot. Each at least one clamp member is constructed and arranged for exerting a vertical compression force on the associated at least one tubular outlet leg for expanding a slurry outlet flow from the at least one leg laterally beyond an exterior surface of the leg.

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 cavity cleaning and coating system for safely and efficiently cleaning and coating the interior of a cavity without requiring entry of any workers. The cavity cleaning and coating system generally includes a mount which is coupled with a movable arm of a vehicle. The mount includes an inner plate, which is coupled to the arm, and an outer plate. A shaft is coupled to the outer plate. The mount is adjustable independently of the arm of the vehicle, including outwardly, inwardly, and rotatably. A spray head is connected to the shaft. The spray head is rotatable and includes a dispenser for dispensing fluids. The vehicle is positioned near a cavity to be treated. The mount is adjusted for optimal positioning of the spray head. The spray head is lowered into the cavity to dispense a cleaning fluid and, after the cleaning fluid has dried, a coating fluid.

A discharge apparatus for discharging contents in an aerosol container, comprising, a first flow channel connected to an aerosol container; a second flow channel connected to the first flow channel; a support configured to support at least a part of the second flow channel; and a change unit configured to change a shape of the second flow channel, wherein the support changes a support position of the second flow channel in response to a change in a shape of the second flow channel, is provided. In addition, an unmanned aerial vehicle on which the discharge apparatus is mounted is provided.

A boom assembly for an agricultural applicator includes a frame supporting a boom arm pivotably coupled to the frame and rotatable about a first axis. A first actuation assembly is pivotably coupled to the frame and the boom arm at a first pivot point for rotation about a second axis on a first side of the first axis. A second actuation assembly is pivotably coupled to the frame and the boom arm at a second pivot point for rotation about a third axis on a second side of the first axis. A sensor is configured to detect data indicative of a relative position of the boom arm relative to the frame. A computing system is configured to activate at least one of the first actuation assembly or the second actuation assembly in response to determining that the boom arm has deviated from a predefined angular range.

An underwater remote cleaning device includes a submersible assembly, a cleaning conduit, and a thruster conduit. The submersible assembly has an upper frame and a lower frame spaced-apart from each other and at least one vertically extending element having a first end and a second end. The first end of the vertically extending element is engaged to the upper frame and the second end of the vertically extending element is engaged to the lower frame. The cleaning conduit is disposed within the submersible assembly with an inlet for receiving a liquid and at least one nozzle disposed on the cleaning conduit for spraying the liquid. The thruster conduit is disposed within the submersible assembly with an inlet for receiving a liquid and at least one nozzle disposed on the cleaning conduit for spraying the liquid.
