    Abstract: The error correction circuit for a computer installation utilises a comparison system for two strings of data-bits (aj, bj, 5=0, 1, .....J-1) for tin operands (A, B). The data strngs pass through a gate control section and split into sections passing through XOR, OR and AND gates. Each group of data on passing through the second set of gates is attached to a parity bit to form an FCC (ERROR corrected code) group. A second parity bit is generated for each corrected string to transmit the corrected data to the next stage of the system. The sequence of checks is carried out in conformity with a decision table.

    Abstract: A gas discharge display/storage apparatus in which a multicolor display is achieved utilizing an arrangement of the triad cell configuration. The triad cell configuration may be positioned on a transparent filter sheet or may be represented by polychromatic phosphor cells formed on the inner surface of the gas discharge display storage apparatus. The triad arrangement representing basic colors of red, blue and green is addressed by horizontal conductors which thread through each of the three cells in the triad arrangement, while the vertical conductors are arrayed in groups of three, each conductor threading the cells of a specific color. The panel can thereby be constructed substantially as a conventional black and white plasma display device, and conventional addressing techniques may be utilized to provide a plasma display with multicolor capability.

    Abstract: A gas discharge display/storage apparatus in which a multicolor display is achieved by a combination of a modified plasma display apparatus and associated cell driving configuration. The apparatus includes two display panels in a sandwich arrangement having one common drive line, the drive system comprising a three-coordinate nonorthogonal selections system, each of the coordinates being displaced by 120 DEG . The individual cells may be arranged in various configurations, each cell having a phosphor representative of one of three basic colors, red, blue and green, whereby coincident selection of selected cells provide the multicolor display.
