Abstract: The cove fixture described herein is formed of an extruded elongated trough body having a series of grooves on the inner face of its side walls, an additional wall extends upwardly from within the body and includes also a groove longitudinally thereof. A fluorescent supporting plate is slidably mounted in the grooves so that one or more fluorescent lamp may be longitudinally adjusted in the body to provide optimum light distribution over the wall of a room where the light fixture is mounted.

Abstract: A mosaic display panel is formed of a series of interconnected horizontal and vertical supports and of a mosaic of tiles and control instruments; a cluster of interfittingly connected elements is provided for mounting the tiles and instruments to the vertical supports; each side wall of each mounting element has a longitudinal projecting tab and a longitudinal guideway, both of substantially complementary shape, so that the tab and guideway of one side wall of this mounting element may be respectively engaged with the guideway and the tab of the side wall of an adjacent mounting element whereby a cluster of such mounting elements may be formed and mounted to two adjacent vertical supports.
