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.

A fire protection nozzle includes a body having two frame arms having proximal ends connected to an outlet of the body, and distal ends, the two frame arms defining a frame arm plane, and a junction formed by the distal ends of the frame arms, the junction including a central bore and an outer wall. A deflector is mounted to the body, and includes a planar member having a mounting hole in a center of the planar member to receive the outer wall of the junction, and a plurality of slots on a periphery of the planar member. The plurality of slots includes first slots, second slots, third slots, and fourth slots.

A sprinkler head nozzle assembly in accordance with an embodiment of the present invention includes an adjustable nozzle operable to extend and reduce an arcuate opening wherein the size of the arcuate opening indicates the arc of coverage of the sprinkler head nozzle assembly and a rotating distributor, mounted on a central shaft extending through the housing and the nozzle member, and operable to deflect a flow of water from the arcuate opening out of the nozzle assembly.

The helicopter drizzle pipe allows for aerial wildfire suppression efforts in otherwise inaccessible areas. The pipe is balanced between the bottom legs of the helicopter as to prevent an imbalance or obstruction to the helicopter rotor blades. Along the bottom of the pipe are strategically placed holes to allow the liquid in the pipe to drizzle out at a constant speed over the whole length of the pipe, simulating rainfall. Due to the pipe's positioning, it is also very easy to remove from the helicopter for refilling or cleaning. Furthermore, the method by which the liquid drizzles from the pipe does not necessitate aircraft movement, thus functioning even when the helicopter hovers to thoroughly cover a specific area.

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.

A smoke generator for anti-burglar purposes comprising canister holding means for holding a canister for chemicals to be used to generate smoke wherein the smoke generator further comprises 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.

A nozzle for an atomizer includes a plate, a piezoelectric actuator, a body, and a connector. The plate defines an aperture. The actuator is configured to oscillate the plate. The body supports the plate. The connector is configured to reversibly mount the body to the atomizer in a first orientation and in a second orientation. In the first orientation, fluid exits the nozzle along a first axial direction through the aperture. In the second orientation, fluid exits the nozzle along an opposite axial direction through the aperture.

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.

A pendent fire protection sprinkler includes a sprinkler body having an inlet and an outlet that define a fluid passage and a sprinkler axis, and a pair of frame arms that form a junction. A deflector, mounted to the junction, includes an annular, planar central portion extending along a plane that is perpendicular to the sprinkler axis, as well as a first portion, a second portion, a third portion, and a fourth portion, each portion extending outwardly from the planar central portion. Each of the first and second portions has a rounded outermost peripheral edge. Each of the third and fourth portions has first, second, and third rectilinear outermost peripheral edges, a respective second rectilinear outermost peripheral edge being located between respective first and third rectilinear outermost peripheral edges, and the first and third rectilinear outermost peripheral edges being obtusely angled relative to the respective second rectilinear outermost edge.

A pendent fire protection sprinkler includes a sprinkler body having an inlet and an outlet that define a fluid passage and a sprinkler axis, a pair of frame arms that form a junction, a plug that seals the fluid passage, and a thermally responsive element provided between the plug and the junction, and configured to maintain the plug in the fluid passage prior to actuation of the sprinkler. A deflector, mounted to the junction, includes an annular, planar central portion extending along a plane that is perpendicular to the sprinkler axis, as well as a first angled portion, a second angled portion, a third angled portion, and a fourth angled portion, each angled portion extending outwardly from the planar central portion. Each of the first to fourth angled portions is bent away from the frame arms in the outlet direction from the plane of the planar central portion.
