A pressure sensitive adhesive layer is provided on the flexible band to affix the device to a suitable vertical surface to display the advertising piece.

Abstract: A marker plate construction for use in terminals, particularly, serially disposed multiple terminals as used in switching appliances. Known marker plates are linked into strips and have to be individually separated from the strip in cases when the juxtaposed terminal blocks have different widths. The marker plate strips according to the invention include tear-off connectors between the individual marker plates which are extensible, or are of variable length in such a manner that the cutting of the marker plate strip during the insertion of the individual marker plates at separate terminal blocks is eliminated.

Abstract: An improved pre-closed slide mount is described having two sides or masks which are secured together for defining an internal pocket to retain a film transparency which is inserted edgewise through an opening or entranceway in one edge of the mount and defining a window for viewing the transparency in the mount. An elevated border region formed in one mask of the mount extends transversely across the entranceway and has a sloping outer surface to provide a funnel for directing a transparency into the entranceway, and this border region has laterally sloping ends which define two spaced valleys the purpose of which is to receive the outer edges of a longitudinally bowed film strip serving as pusher for the inserted transparency. The outer edges of the valleys are defined by lateral transparency guides. The border region of the other mask forms an elevated roof over the elevated border region with inverted steps over the laterally sloping end portions of the border region.

Abstract: An attractive dynamic star burst display is provided in which a plurality of light sources preferably of different colors, are mounted behind a translucent enclosure, and relative movement is provided for effectively changing the distances between the light sources and the regions of the surface where their various rays are being viewed. The translucent enclosure includes a layer of intrinsically transparent material having a smooth inner surface facing the light sources and an embossed outer surface having a multifaceted pyramidal prism system for directing rays of light from the light sources in dynamically changing light patterns in accordance with the optical and geometric relationship involved, including the position of the viewer's eyes, the multi-facets on the embossed outer surface and the effective distance between the respective light sources and the respective regions on the embossed outer surface where the rays of light are being seen.

Abstract: An improved slide for electrophotographic film which comprises a pair of slide frame forming panels hingedly connected along adjacent edges enabling the panels to be folded together in superposed relation. The inner surfaces of each panel is coated with a pressure sensitive adhesive which bonds an electrophotographic film to one panel. A transparent protective film or a second photographic film may be bonded to the other panel. A conductive foil strip is affixed along an edge of the film for providing a grounding contact required for imaging the film in a duplicating camera and a release paper is disposed over the adhesive coating of the other panel. Subsequent to imaging, a slide is formed by stripping off the release paper and folding the panels so that the adhesive coating bonds the inner surfaces together with the film being retained therebetween.

Abstract: A novel type of preprinted index strip is disclosed for use in microfiche storage panels and similar devices of the type adapted to hold and display index strips along one edge. This new type of index strip greatly expands the choice of identification symbols available to the user from a single preprinted index sheet without requiring a reduction in the size of the identification symbols or prohibiting the same identification symbol from being displayed on both sides of the storage panel.

Abstract: An emergency warning traffic sign comprises a conventional stop sign which has been divided vertically in the middle into two sheet portions carrying portions of the message on one face of each of the sheet portions. The sheet portions are connected by a hinge such that a first of the portions may be mounted to a traffic signal post and the second sheet portion may be rotated between a first position in which the message is obscured to a second open message position. A locking bar is attached to the first sheet portion and is pivotally movable across the back of the sign and within its perimeter to lock the sign in both its open and closed positions. In a second embodiment of the invention, another sign carrying a different message is also divided vertically into a third and forth sheet portions and these sheet portions are hingedly connected to each other.

Abstract: An illuminated advertising display device produces changing visual effects by placing a panel having a pattern of holes at the front of a light box with some of the holes defining alpha-numeric characters, and reciprocating behind the panel a shutter which has a pattern of transparent spots each of which registers with a hole in the panel at some point in the reciprocation of the shutter, with some of the spots registered simultaneously with all the holes that define the alpha-numeric characters. The panel has a forwardly facing reflective surface, and spaced forwardly of the panel is a light transmitting reflective sheet. If desired, the transparent spots may be tinted in several different colors.
