Abstract: A fluid sprayer includes a fluid storage module having at least one fluid tank, and a dispersion module having a rotary spray head assembly in fluid communication with the tank to receive fluid therefrom. The rotary spray head assembly further atomizes the fluid, and the dispersion module further includes a blower assembly positioned upstream of the rotary spray head assembly for dispersing the atomized fluid from the rotary spray head assembly into the surroundings of the fluid sprayer. The fluid storage module is detachably coupled to the dispersion module to effect reconfiguration of the fluid sprayer between a first configuration in which the fluid storage module and the dispersion module are positioned in a side-by-side manner, and a second configuration in which the fluid storage module and the dispersion module are positioned in-line with each other.

Abstract: A rotary spray head assembly includes a motor having an output shaft and a housing through which the output shaft at least partially extends. The housing includes an inlet communicable with a source of fluid. The rotary spray head assembly also includes an annular skirt extending from the housing, a passageway through the skirt having a first end in fluid communication with the inlet and a second end, and a hub coupled for co-rotation with the output shaft. The hub includes an annular groove into which the annular skirt at least partially extends, a circumferential interior surface at least partially defining the groove, and an aperture through the circumferential interior surface. Fluid introduced into the annular groove through the second end of the passageway is discharged outwardly through the aperture.

Abstract: An alpha-numeric array is provided for the selective display of characters as controlled by associated character generator programming circuitry. The display array in one character format utilizes a 5.times.7 matrix array of individually operable illumination sources, LED solid state lamps for example, with programmed combinations of the individual illumination sources being operated to display the programmed characters. The display array includes a lens and front panel array having integrally formed lens areas. The lens areas of the lens and front panel array when unactuated are essentially indistinguishable from the front panel array background area thus providing improved contrast. The display array also includes a reflector array having integrally formed reflector cavities. The integrally formed reflector cavities include predetermined surface characteristics for collimating the light rays emanating from the central axis of the reflector cavities.
