Abstract: In a drain device for purging compressed air lines of water, oil, sludge, and other contaminants by the alignment of a first pair of apertures in a valving mechanism to allow the contaminants to enter a central chamber and periodically moving the central chamber to align a second pair of apertures to allow the contaminants to flow from the chamber, a pair of seals are provided for sealing each of the pairs of apertures. One seal is concentric with the one aperture in order that, with the apertures aligned, the seal will prevent leakage into or from the interior of the housing. A second seal encircles the first seal and extends radially away from the first seal in a direction coincident with the movement of the chamber portion which causes misalignment of the apertures. Accordingly, the second seal prevents escape of contaminants from the misaligned apertures while the first and second seals cooperate in the misaligned mode to prevent communication of the two apertures.

Abstract: An asphalt mix storage bin outlet is surrounded by a rim member having a flat bottom surface in which there is an annular groove that extends around the outlet. An outlet closure comprises a plate-like edgewise slidable gate member mounted on rollers that ride on parallel rails at opposite sides of the outlet. The rails have long, straight portions along which the gate member rides to and from its open position with its top surface spaced below the bottom surface of the rim member, but as the gate member nears its closed position it rides up onto wedge-like portions of the rails that cam it towards snug engagement of its top surface with the bottom surface of the rim member. For an airtight seal with the gate member closed, grease is forced into the groove in the rim member, to be distributed around the outlet by the groove and thence forced into any space between the opposing surfaces of the rim member and gate member.
