Abstract: An office building has a glass paneled exterior with transparent window panels extending from floor to ceiling of each story and a horizontal row of panels of translucent glass positioned adjacent the floor or the ceiling of a single story building or between the top portion of one story and the bottom portion of the next story in a multi-story building. An illuminated sign is provided comprising a plurality of electrically illuminated sign modules aligned linearly behind some of the translucent glass panels, which comprise a plurality of individual lights, selectively illuminable in the form of any one of a plurality of selected alphanumeric characters or symbols. The individual lights, when energized, provide light of an intensity sufficient to be seen outside the translucent glass panels but are invisible from the outside when deenergized. Control switches, etc., are provided for selectively energizing the lights on selected ones of the sign modules.

Abstract: A novel fingernail hone consists of a body of unglazed ceramic material having a honing or polishing surface in the form of a concave surface which is unglazed and of substantially spherical curvature. The ceramic material is preferably in the form of an elongated stick, preferably of cylindrical shape, with the concave unglazed surface in either or both ends. An alternate embodiment may include a sharpening or polishing notch in one end or extending longitudinally of the cylindrical surface of the ceramic stick.
