Abstract: The present invention relates to an improved cleaning solution applicator for use in a hot water carpet extractor. The applicator comprises an elongate, multi orifice, liquid distributor positioned within the discharge opening of an air distributing nozzle. Warm moist exhaust air discharged from the extractor's suction fan is directed through the air nozzle passing over top of and underneath the liquid distributor converging down stream of the liquid distributor and before exiting the air nozzle's exit opening. Liquid exiting the liquid distributor's orifices is thereby atomized and conveyed, by the flow of air from the air distributing nozzle, toward the surface being cleaned.

Abstract: The invention comprises a cleaning apparatus having interchangeable cleaning solution supply reservoirs, a fluid pump, a vacuum fan, and a removable recovery tank, all cooperatively arranged in a housing of a unique compact design.

Abstract: This invention is a method for remotely obtaining roadway crown point elevation and horizontal location based on projecting a horizontal laser beam configured vertically in either a continuous or discrete manner across the roadway surface at a predetermined elevation substantially coincident with the crown point of the roadway. The highest elevation of the roadway partially occludes the vertically configured laser beam. The lowest elevation of the laser beam which contacts an array of vertically configured laser receivers positioned on the opposite side of the roadway is by necessity the highest elevation of the roadway crown. By using an optical detector at a known vertical offset from the laser beam emitter, the angle and hence the distance can be determined to the furthest laser impact with the roadway. This distance information can be combined with the known line between the laser emitter and laser receivers to resolve the horizontal coordinates of that point.
