Abstract: A support mechanism for raising and lowering a terminal monitor comprising an upper assembly and a lower assembly and a plurality of pivotable arms interconnecting the upper assembly and lower assembly. The upper assembly includes an upper plate, which supports the monitor, and an upper slidable plate slidably coupled to it, and the lower assembly includes a base plate and a lower slidable plate slidably coupled to it. Due to the way the pivotable arms are coupled to the various plates, when the upper slidable plate is driven with respect to its associated upper plate, the arms pivot either to raise or lower the upper assembly and its monitor load with respect to the lower assembly.

Abstract: The method of making a display panel 10 comprising forming an assembly of a glass base plate having a set of longitudinal first slots in which anode electrodes are secured and having an array of cathode electrodes seated on the top surface of the base plate and oriented transverse to the anodes. An apertured electrode plate is disposed adjacent to the base plate and its electrodes, and a face plate assembly is prepared by providing a glass plate and forming on one surface, in order, a large-area electrode and one or more insulating layers, after which an apertured insulating layer is formed thereon by a photo-etching process. The face plate assembly carrying the apertured insulating layer is assembled with the other parts of the panel, and the panel is processed to completion.

Abstract: A display panel comprising a matrix of D.C. scan cells arrayed in rows and columns and a matrix of A.C. display cells arrayed in rows and columns, each scan cell being in operative relation with two display cells so that for every column of scan cells there are two sets of display cells.

The panel also includes an array of display cells formed by an array of row display anodes and the same cathodes, the display anodes operating with restricted areas on the top surfaces of the cathodes to provide cathode glow. The rows of display cells are offset from the rows of scan cells so that the glow transfer path and display glow cells are disposed in an optimum location for panel operation and life.
