Abstract: An energy control sheet, including a highly transparent substructure having first and second surfaces, a substantially transparent, thin film metal layer formed on one surface of the substructure, and a highly transparent thin film dielectric layer formed over said metal layer. The dielectric layer comprises a mixed metal oxide layer having metal constituents of at least one lanthanide series metal (e.g. cerium oxide) and at least one transition or semiconductor metal (e.g. tin oxide). The dielectric layer is characterized by substantial water vapor impermeability so that the weatherability of the energy control sheet is substantially improved. The metal layer is either a silver layer or a silver-palladium alloy.

Abstract: A protective crowd control barrier for maintaining observers in spaced relationship to an article being displayed such as an automobile or the like in which the barrier includes a plurality of adjustable uprights which receive a flexible barrier member in a manner such that the flexible member is spaced from and extends entirely around the article. The uprights are selectively adjustable to alter the elevation as well as the spacing of the barrier member from the article being displayed.
