Abstract: The present invention provides a reinforced plastic laminate structure comprising an elongated reinforcing material that is encapsulated by an extruded plastic material that forms a continuous structure around the reinforcing material. The present invention contemplates methods of extruding a tube of plastic material while simultaneously introducing a reinforcing material within the interior of the tube. Thereafter, the tube is flattened so that the interior wall of the tube comes in contact with the reinforcing material to encapsulate the reinforcing material in a continuous structure. The reinforced plastic laminate sheet is made from an apparatus an extruding machine for extruding plastic with an annular die and opening for the extruding tubing. Attached to the extruding machine is a mandrel which feeds a reinforcing material into the center of the annular opening. Pressure rollers flatten the tubing after it exits from the annular die.

Abstract: A two-part glazing system for use on the lower rails of the upper and lower sashes of a double-hung window. The glazing system comprises a moisture impervious liner member which is snap fit onto the lower rail and underlies the lower edge of the windowpane. A glazing bead is snap fit onto the liner member and extends therefrom to the face of the windowpane. The glazing bead has a gasket for sealing against the windowpane and defining an enclosed drain tank. The gasket prevents substantial amounts of water from reaching the drain tank. Any moisture which does reach the drain tank is drained away through outlet holes in the liner member.
