The bits were stored as discrete regions of charge on the smooth surface of the signal plates.
2.
Writing was accomplished by selecting a bit, as above, and then sending a pulse of potential, either positive or negative, to the signal plate.
3.
If the dielectric for that bit contained a charge, the electrons would be pushed off the dielectric and read as a brief pulse of current in the signal plate.
4.
While the iconoscope and the intermediate orthicon used capacitance between a multitude of small but discrete light sensitive collectors and an isolated signal plate for reading video information, the image orthicon employed direct charge readings from a continuous " electronically charged " collector.
5.
It had an indirectly heated cathode running up the middle, surrounded by two separate sets of wires one radial, one axial forming a cylindrical grid array, and finally a dielectric storage material coating on the inside of four segments of an enclosing metal cylinder, called the " signal plates ".
6.
His most characteristic works are his signal plates ( small round decorated plates designed to be hung in groups on the wall ) and his Grecian urn-shaped vases, where the form is built by flattened coil construction in terracotta, then the exterior is slab-cut with wire; top openings are cut with wire in trefoil or quatrefoil shapes, giving glimpses of the unglazed terracotta interior, while the body is decorated in painted glazes.
