Abstract: A sign structure having a copy board which is movable across the face of the structure and which releasably mounts display symbols such as numeric and alphabetic charactrers. The copy board comprises a frame which is mounted to the sign structure via rollers and may be positioned at will along the length of the sign structure adjacent to, overlapping, or removed from a vignette, etc., displayed on the sign face. Retainer bars extend between opposite sides of the copy board frame and are adapted for releasably mounting symbols by engaging slots formed in the symbols. Great flexibility is provided in positioning the symbols, for the copy board frame can be positioned at will along the sign, the retainer bars can be positioned substantially anywhere along the copy board frame in the direction perpendicular to their length, and the symbols can be positioned at will along the length of the retainer bars.

Abstract: A supporting frame with a handle has a transparent supporting plate mounted therein. The plate supports a thin transparency over the exposed surface of the plate. The transparency has a multiplicity of demagnifying fresnel lenses formed therein in abutting relation and in vertical and horizontal rows. The lens areas are rectangular in outline with very fine and closely spaced concentric light refracting grooves formed in one surface of the transparency and extending to the edges of the several areas. The frame has retaining shoulders therearound for removably holding one of several different opaque silhouette cards of different household furnishing articles, which are provided, along one edge of the frame.
Abstract: A display device arranged to present selectively three different displays. The displays are formed by three sets of display panels with two of the panel sets being selectively movable as a unit relative to the third and movable relative to each other and to the third to provide the selectively different panel displays. Selective movement of the panel sets is effected by a control which, in the illustrated embodiment, includes a camming element which is guided in a plurality of angularly related paths to effect the desired selective disposition of the different panel sets.
Abstract: A slide chart made from an elongated card and particularly adapted to be self-assembled for use as a calorie counter for food products, such as soft drinks, cereal products and the like. The card may be inserted in a carton or other container for food products in its elongated form and may be assembled by the purchaser into a slide chart to give the calorie content of selected food products listed on opposite sides of the slide chart along opposite sides of slots on opposite sides of the chart. The elongated card has a locking tab at one end and a slide card separable from its opposite end.
