Abstract: A solar panel is shown for use as a double panel window structure. It has an outer frame formed by an H-shaped extrusion that has one of its outermost legs shortened, and a pair of generally parallel legs or flanges that are inwardly directed of the frame. The outer surface of these flanges are furnished with a dual pressure-sensitive adhesive tape having a width between 1/4 inch and 1 inch. A pane of transparent material is sealed around its periphery into engagement with the adhesive tape for forming a double pane solar panel. Several modifications are also shown for exerting a mechanical locking force on at least one of the panes.

Abstract: A smoke suppressed rigid or plasticized polyvinyl chloride polymer composition contains a polyvinyl chloride polymer and a small but effective amount of a smoke suppressant consisting essentially of a mixture of Zn.sub.3 Mo.sub.2 O.sub.9 .multidot.H.sub.2 O and ZnHPO.sub.3, in an atomic ratio of Mo to P of about 0.5:1 to about 2.0:1, to impart smoke suppression to the polymer composition.

Abstract: A flame resistant and smoke suppressed plasticized polyvinyl chloride polymer containing from about 20 to about 100 parts per hundred resin (phr) of a plasticizer comprising an ester-type primary plasticizer in combination with a controlled amount of a chlorinated paraffin or organic phosphate ester secondary plasticizer and an effective amount of a flame retardant and smoke suppressant agent comprising inorganic molybdenum compounds, such as molybdenum oxides and metal molybdates. In accordance with a preferred embodiment, the flame retardant and smoke suppressant agent further includes a controlled effective amount of antimony oxide in combination with the molybdenum compound imparting synergistic flame retardancy and smoke suppressing characteristics to the plasticized polyvinyl chloride resin formulation.

Abstract: A flame resistant and smoke suppressed plasticized polyvinyl chloride polymer containing from about 20 to about 80 parts per hundred resin (phr) of an ester-type plasticizer and an effective amount of a flame retardant and smoke suppressant agent comprising an inorganic molybdenum compound such as molybdenum oxides and metal molybdates. In accordance with a preferred embodiment, the flame retardant and smoke suppressant agent further includes a controlled effective amount of an antimony compound such as antimony oxide in combination with the molybdenum compound imparting synergistic flame retardancy and smoke suppressing characteristics to the plasticized polyvinyl chloride resin formulation.

Abstract: A flame retardant styrenic synthetic polymer containing a flame retardant agent comprising a mixture of a molybdenum compound selected from the group consisting of molybdenum trioxide, ammonium dimolybdate, and ammonium heptamolybdate, in combination with a halogenated hydrocarbon compound selected from the group consisting of halogenated aromatic compounds, halogenated cyclic aliphatic compounds, and mixtures thereof.
