Abstract: A pipe (12) coupling assembly (16, 116) includes a body (64, 120), a rib (65, 122), and teeth (56, 124). The body (64, 118) has an outer diameter and first and second inner diameter sections (68, 128, 70, 130). The first inner diameter section (68, 128) is wider than the second inner diameter section (70, 130). The rib (65, 122) extends around the first diameter section (68, 128) and projects radially inwardly therefrom. The teeth (56, 124) are situated within the second inner diameter section (70, 130) and project radially inwardly toward a central axis (38, 134) of the body (64, 120).

Abstract: An interior storm window that comprises a frame having one or more panels with outer and inner covers of double polished virgin vinyl plastic film with an air space therebetween. The outer frame edge is tapered at an angle of about 20.degree. and a strip of polyurethane foam is attached to the outer frame edge so that a progressively tighter friction fit is provided with the interior window frame of a house or other building. The storm window, particularly for large window frames, is in the form of two or more panels hinged together and locked together while in the same plane. A single foam edge may be provided on one of the pivoted window panels that adjoins the other.

Abstract: An interior storm window comprising an adjustable seal extending about the perimeter of the storm window and being in the form of a strip of extruded, flexible plastic material having an inverted "U" shape with a sealing bead extending upwardly from the bight of the "U" and spaced arrow-shaped portions extending downwardly from each side of the bead. The end portions extend into correspondingly shaped openings in an extruded frame of rigid plastic material which surrounds a pair of glazing sheets whose outer perimeters extend into and are firmly supported by the frame.
