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.

A fog generator assembly includes a water vapor generator, a fragrance dispenser, and a mixing element fluidly coupled to the water generator and the fragrance dispenser. The mixing element is configured to mix a fog of water vapor from the water vapor generator with a fragrance from the fragrance dispenser to produce an aromatic fog.

In one embodiment, a spray gun light includes an aperture configured to allow the spray gun light to attach over an air cap of a spray gun. The spray gun light also includes multiple horn clips. Each horn clip is configured to couple to a respective horn of a plurality of horns of the air cap of the spray gun. The spray gun light also includes a plurality of lights that include a first light configured to shine light along a first side of a spray plume generated by the air cap, and a second light configured to shine light on along a second side of the spray plume that is opposite the first side. The spray gun light is configured to rotate along with the air cap as the air cap is rotated, thereby preventing light from the plurality of lights from being blocked by the spray plume.

Coat-in-place assemblies and methods to provide an aesthetically pleasing sprinkler assembly. A coat-in-place assembly includes a sprinkler body having a proximal portion and a distal portion, a thermally responsive trigger disposed adjacent the distal portion; and an escutcheon centered about the distal portion of the sprinkler body to define a void between the sprinkler axis and the escutcheon. A coating-inhibiting-cap encloses and protects the thermally responsive trigger between the sprinkler body and the cap. The cap extends into the void and is radially spaced inward relative to the escutcheon so as expose surfaces of the escutcheon for coating.

A device for artificially generating road spray and a method are provided. The device includes a frame, a roller, and a reservoir, wherein the roller is rotatably mounted on the frame and wherein the device is configured to supply a liquid from the reservoir to a surface of the roller. The method includes supplying water and/or a suspension comprising water to a surface of a rotating roller and exposing a vehicle to road spray generated by the rotation of the wetted roller.
