Abstract: A static classifier cage is formed in upper and lower tiers of circumferentially spaced bar-shaped vanes of wear-resistant material. The lower tier is formed by and between a bottom ring and an intermediate ring. The top tier is formed by and between the intermediate ring and a topmost ring. In each tier, the lowermost ring is provided with slots to receive and act as a seat for the vertically oriented vanes while the upper ring in the tier is provided with radially outwardly opening notches into which the vanes are moved in a radial fashion. After the vanes are installed, a retainer is fastened into position to prevent the vanes from backing out of the notches.

Abstract: A car wash arch of inverted U-shape with a centrally mounted pendant on the overhead horizontal section, the pendant being of such size and shape as to accommodate a logo or other indicia therein. Light tubes, preferably containing LEDs extend upwardly along the vertical sections of the arch, inwardly along the horizontal section of the arch and into the pendant so as to at least partially frame and illuminate the pendant. A fluid conduit feeding a system of nozzles can be mounted to the arch and supply car wash fluids to spray nozzles inwardly from the vertical and horizontal arch sections.
