Abstract: An installation system for use with a window assembly with a nailing fin in a rough opening of a wall, the rough opening including a sill. The system includes a sill drain mat including a barrier wedge with a front edge, a rear edge, a bottom surface and a top surface. A fiber layer includes a top surface and a bottom surface and an adhesive layer disposed on the bottom surface of the fiber layer. A first portion of the fiber layer is adhered to the top surface of the barrier wedge and extends inwardly, the first portion of the fiber layer including a sealing strip. A second portion of the fiber layer extends outwardly from the front edge and the bottom surface of the barrier wedge forms a mating surface with a sill of the rough opening. A gasket includes a first surface attached to an inner surface of the nailing fin, a second surface received adjacent an outer surface of the wall, and an outer edge comprising a protruding end extending along a length of the gasket.

Abstract: Classifying and processing post-consumer plastic scrap materials for subsequent utilization. Post-consumer plastic scrap of various kinds, such as colored HDPE, natural HDPE, green PET and clear PET are separating into constituent fractions, and each fraction is separately reduced to flakes. At least some of the fractions are separately washed to remove fragments of labels or other foreign matter previously in place on the plastic bottles or other containers making up those scrap constituents.

Abstract: A thermal gravity classifier in which various nonferrous scrap metals are classified and separated, using a single tank containing two layers of molten media. Shredded nonferrous scrap containing metal constituents such as aluminum, zinc, lead, and copper or the like are introduced to the top of the tank containing an upper layer of molten zinc, floating on a lower layer of molten lead. Metals such as aluminum, having a specific gravity less than zinc, by a screw conveyor approximately parallel with the top surface. Heavier metals and alloys such as copper or the like, having a melting point above the temperature within the tank, fall through the zinc layer and are conveyed from the tank by a separate screw conveyor extending up a diagonal wall of the tank. Metals such as lead and zinc, having a melting point lower than the temperature maintained within the tank, melt and gravitate to the appropriate molten layer in the tank.
