Abstract: A chipseal overlay coating having in situ deicing properties. An absorbent material such as lightweight aggregate, is mixed with oil, asphalt and/or concrete to form a thoroughfare chipseal overlay. Deicing materials are applied to the overlay or to the absorbent material prior to the mixing process. Due to the highly absorbent nature of the chipseal overlay, the deicing material is absorbed. During icing and snow conditions, the impregnated material reacts with the ice and snow to cause them to melt.

Abstract: An improved drapery fabric, constructed of an open weave decorative fabric adhesively-bonded by a flexible inner bonding stratum to a flexible solar control film. The solar control film permits visible light transmission through the open weave decorative fabric and reduces heat loss, or gain, by reducing the flow of heat and air therethrough. In addition, the improved open weave drapery fabric reduces heat loss during winter months through the combined effects of reflective and barrier characteristics, as well as the stagnant air space created between the window glass and the improved drape.
