Abstract: A ridge vent has an elongated body having a width sufficient to span the ridge of a roof along which the ridge vent is installed. Tear lines of relative weakness are formed at spaced intervals along the elongated body. The tear lines may be formed by score lines, perforations, or otherwise and are configured to allow the body of the ridge vent to be separated manually at a selected tear line by grasping the body and tearing along the tear line. Depending partitions may be disposed on the underside of the body on either side of each tear line to form end walls at new ends formed when the ridge vent is separated along a tear line.

Abstract: A method of and apparatus for the immersion treatment of discrete lengths of galvanized conduit to inhibit the formation of "white rust" on the conduit surfaces are disclosed. The conduit is continually conveyed successively through three treatment zones comprising a cleaning bath containing a cleaning agent which removes lubricating oils, greases, dirt and the like from the conduit interior and exterior surfaces, a rinse bath and a coating bath containing a coating agent including chromate ions and a polymeric coating composition. A rotary star wheel-type conveyor is arranged in each treatment zone for transporting the conduits in spaced, substantially parallel relation to each other about an arcuate path through each bath and for inclining the conduit above the bath for a time effective to drain excess liquid from the interior and exterior conduit surfaces. Effective draining of excess liquid prior to entry to another zone minimizes contamination of the various baths and yields a high quality product.
