Abstract: A molded part containing plastic substrate and a firmly adherent coating thereon, the plastic substrate containing a filler therein present at least in part in proximity to the surface of the substrate. The coating is transferred from the mold surface to the substrate during the molding operation and during solidification of the molded part. The molded part has a smooth surface as molded and without any subsequent finishing thereof.

Abstract: Means for releasably holding a window or screen in a door frame. The door frame has a continuous flange around an opening to support one side of a window or screen and a plurality of recesses adjacent the opening. A slidable tab within each recess has an elongated slot therethrough and at least two runners on the underside upon which to slide the tab to and from an extended position within the recess. A threaded means passes through the elongated slot in the tab to a threaded hole in the base of the recess to releasably hold the tab in a selected fixed position. The tabs in extended position securely but releasably hold the window or screen against the flange on the frame.

Abstract: A plastic storm door comprising a unitary molded plastic panel having an integral solid skin. The panel has a channel along its peripheral edge having integrally molded load-transferring ribs diagonally traversing the width thereof. Hinges are secured along a vertical edge of the panel by attachment to tapping plates mounted within the channel between and bridging two of the load-transferring ribs. The ribs act to uniformly distribute the loading forces on the hinges throughout the panel. Elongated plastic strips enclose the channel to form an insulating airspace therein.
