Overlay Indicator Display

This is a display system with extended displaying ability requiring relatively few indicators. This system consists of four main parts. The display overlays, the display reading board, the display overlay storage, and the display selector.

The display overlays 10 are plastic cards, for example, eight by eighteen inches in size. Each card is capable of containing six thirty-six bit words of display information. Each strip of word display is one inch high and eighteen inches wide. The lower half of this strip is divided into thirty-six half-inch square boxes. Each half-inch square is translucent and contains graphic characters or numbers to identify a particular bit position (to be lit from a lamp in the reading board underneath when its bit position is active). The upper half of the one inch word strip is used for nomenclature or description of the represented bits. A small area at the right side bottom of the card contains punched holes. These holes are coded to identify the card for correct data display.

The display reading board 12 is an inclined plane covered with a piece of glass. Beneath the glass surface is the indicator assembly. This assembly is made up of six plastic egg-crate strips 14. Each strip contains thirty-six square boxes, with an indicator lamp in each box. The egg-crate structure provides the necessary rigidity to support the overlay.
