Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
88 words
A METHOD OF MANUFACTURING A PLATE OR SHEET HAVING AN ELECTRICAL CONDUCTIVE NON-ALKALI METALLIC PLATED COATING WHICH COMPRISES TAKING A BASE SHEET OF FLEXIBLE, IMPREGNABLE PAPER MATERIAL, EVAPORATING A NON-ALKALI METALLIC FILM ON ONE SURFACE THEREOF, THEN PLATING OVER THE FILM A CONTINUOUS NON-ALKALI METALLIC COATING, WASHING, RINSING AND DRYING THE SHEET, IMPREGNATING THE UNPLATED SIDE ONLY WITH A LIQUID THERMOSETTING RESIN, PARTIALLY CURING THE SAME ON THE SHEET AND FINALLY CURING TO THE PARTIALLY CURED FACE OF SAID SHEET WITH HEAT AND PRESSURE A THERMOSETTING BASE SHEET.
Claim 2

Claim 3
Dependent Claim
92 words
A PLATE OR SHEET HAVING A CONDUCTIVE NONALKALI METALLIC PLATED COATING COMPRISING A SHEET OF PAPER MATERIAL HAVING DEPOSITED ON ONE SIDE THEREOF A THIN NON-ALKALI METALLIC FILM OF SEVERAL MICRONS THICK, A CONDUCTIVE NON-ALKALI METALLIC PLATED COATING DEPOSITED ON SAID NON-ALKALI METALLIC FILM OF SUBSTANTIALLY .001'''' IN THICKNESS, A THERMOSETTING PLASTIC RESIN FORMING A COATING OVER FILLING THE INTERSTICES IN SAID PAPER SHEET AND IMPREGNATING SAID PAPER FROM THE SIDE OPPOSITE TO THAT ON WHICH SAID METALLIC FILM IS FORMED AND A THERMOSETTING SHEET CURED TO SAID THERMOSETTING PLASTIC RESINOUS COATING.
Claim 4
Dependent Claim
