Abstract: A holder is made from flexible material and is held in tracks of a conventional reader board. The holder has upper and lower edges that lie in a common plane and are normally separated by a first distance. A middle region lies forward of the common plane. The middle region includes channels having downwardly converging surfaces for removably receiving a decoration with similarly converging sides in wedging engagement. At removal, a person uses a suction cup to grip the decoration. Force applied to the suction cup pushes the decoration and the holder middle region toward the reader board, causing the holder middle region to flex and increase the distance between the upper and lower edges of the holder, hence moving the edges farther into the reader board tracks. The holder lower edge is then unable to slide upwardly and come out of the reader board and fall on the person.

Abstract: The present invention is a method for forming a cohesive display object and associated display items. The invention contemplates a display object which is at least partially covered with flock (crushed fiberous material, such as rayon) and at least one display item which back side is at least partially covered with flock. The method comprises the steps of coating at least part of the surface of the display object and the back of the display item with a non-drying adhesive; then covering the coated surface with flock. Contact of the adjacent flock-coated surfaces of the display object and items will create a cohesive force and removably secure the display item to the display object.

Abstract: A sheet of electroluminescent material in the shape of an alphanumeric character is embedded in a rigid base. An exciter unit for transforming incoming electric power to the appropriate voltage and frequency for driving the luminescent material is also embedded in the base behind the character. Each character, base and exciter unit thus form a self-contained display module. A universal interconnecting member is used to electrically and mechanically interconnect the module to any other module with the proper horizontal or vertical spacing. The gap between adjacent display modules may be filled with either a cover or an electrically active header which contains such devices as an electric eye for applying power to the modules after dark or a rechargable battery charged by either an external power supply or an internal solar cell.

Abstract: Apparatus is provided for making a permanent mark on a hard surface such as glass or the like primarily for identification purposes. A hand held gun connected to a source of compressed air is adapted to drive a stream of abrasive particles towards a stenciling head on the marking end of the gun, which is held against the surface to be marked. The head carries interchangeable stencils located in the path of the stream of abrasive particles when the gun is actuated. When the stencil head of the gun is held flat against the surface which is to be marked and the gun actuated, the stencil indicia will be formed on the surface by the action of the abrasive particles abrading and etching the surface through the stencil openings. The stencil elements are formed by photo engraving techniques to produce sharp, precise characters and the elements themselves fit snugly together when assembled to prevent leakage between adjacent elements.
