A smoke generator for anti-burglar purposes includes a canister holding means for holding a canister for chemicals to be used to generate smoke wherein the smoke generator further includes a smoke deflector arranged below the position of the canister for even distribution of generated smoke, and wherein the smoke deflector have a smoke deflector cavity of sector shape. The smoke generator is provided with a cartridge for the canister to ease replacement of used or expired canister. The smoke deflector is provided with a residual collector to prevent residuals and debris from littering the room where the smoke generator is used.

An adjustable arc irrigation spray nozzle can include one or more features including a dual orifice, a multi-trajectory ramp, radial ribs, an impedance wall, and/or a variable orifice.

Treatment system (100) for treating workpieces (102), having a treatment region (108) for receiving workpieces (102) to be treated, and a plurality of operating devices (130) for performing one or more operations on the workpieces (102) to be treated.

A sprinkler head nozzle assembly including a movable nozzle guard movable to selectively cover and uncover a nozzle to prevent debris from entering the assembly.

A mobile washing robot and a method of cleaning a stable, wherein the mobile washing robot has a chassis, at least one drive mechanism, an undercarriage, at least one cleaning arm, and a computer control unit, with at least one radar sensor by means of which the dimensions of a stable area to be cleaned are automatically measured and/or obstacle detection is automatically performed. Data thus obtained is automatically made available to the computer control unit for calculating a position of at least one cleaning arm and a travelling speed, a position of at least one nozzle head, a position of at least one nozzle, an activation/deactivation of at least one nozzle and/or a flow rate of a fluid within a nozzle, so that a user does not have to perform any teach-in procedure with regard to the stable area to be cleaned, making savings in personnel costs possible.

Treatment system (100), having a treatment region for receiving workpieces (102) to be treated, and one or more operating devices (130) for performing one or more operations on the workpieces (102) to be treated.

An atomizer for applying a coating includes a nozzle plate, an actuator, and an acoustic focusing device. The nozzle plate defines at least one aperture. The actuator is configured to oscillate to form pressure waves within a fluid to eject the fluid from the nozzle plate. The acoustic focusing device focuses the pressure waves toward the apertures.
