Abstract: A METHOD OF CONSTRUCTING A FACEPLATE IS DESCRIBED, WHICH CONTAINS A MULTITUDE OF CLOSELY SPACED, DISCRETE, CONDUCTIVE ELEMENTS TO PERMIT PASSAGE OF ELECTRICAL SIGNALS FROM ONE SIDE OF THE FACEPLATE TO THE OTHER. THE FACEPLATE IS COMPLETELY IMPERMEABLE TO GASES. THIS METHOD COMPRISES PLACING A METAL BAR PATTERN ON RIBBON GLASS, CUTTING AND STACKING SHEETS OF THE GLASS, AND SUBJECTING THE STACK TO HEAT AND PRESSURE. THE METHOD OF CONSTRUCTION PERMITS THE READY PLACEMENT OF A LARGE NUMBER OF CLOSELY SPACED DISCRETE CONDUCTING PATHS TRANSVERSELY THROUGH THE FACEPLATE MAKING POSSIBLE TWO-DIMENSIONAL ARRAYS OF 500 OR MORE ELEMENTS PER INCH.
