Claim 1
Independent Claim
188 words
A PROCESS FOR MAKING AN ELECTROMAGNETIC ENERGYSHIELDING FLAT GASKET ADAPTED TO SEAL A JOINT ELECTRICALLY CONSISTING ESSENTIALLY OF THE STEPS OF: (A) PREPARING A PASTY MIXTURE OF A LIQUID PLASTIC COMPOSITION THAT CURES TO AN ELASTOMER CONTAINING WITHIN THE RANGE OF 70 TO 93 WEIGHT PERCENT OF A METAL POWDER HAVING A CONTINUOUS OUTER SURFACE OF A NOBLE METAL; (B) FORMING A SHEET BY SPREADING THE HEAVY PASTE SO OBTAINED INTO THE INTERSTICES OF A WIRE MESH USING THE WIRE MESH TO SET THE THICKNESS OF THE SHEET, THE AMOUNT OF SAID HEAVY PASTE AND THE THICKNESS OF SAID WIRE MESH BEING SUFFICIENT TO YIELD A SHEET HAVING A FINAL THICKNESS IN THE RANGE OF 4 TO 100 MILS THE PLANE OF SAID WIRE MESH BEING PARALLEL TO THE PLANES OF THE TWO SEALING SURFACES OF THE GASKET; (C) CURING SAID SHEET USING CURING CONDITIONS APPROPRIATE TO THE SPECIFIC LIQUID PLASTIC COMPOSITION TO CONVERT THE SAME TO AN ELASTOMER WHILE MAINTAINING THE PARTICLES OF SAID METAL POWDER IN ELECTRICAL PARTICLETO-PARTICLE CONTACT; AND (D) CUTTING FROM SAID SHEET A GASKET OF A SIZE AND SHAPE TO FIT SAID JOINT.
