Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
85 words
AN ELECTRICALLY CONDUCTIVE PAPER FORMED OF A MAJOR PROPORTION OF UNCOATED NON-CONDUCTIVE FIBERS AND A MINOR PROPORTION OF ELECTRICALLY CONDUCTIVE METAL-COATED FIBERS COMPOSED OF CHEMICALLY INERT MATERIAL AVING A SMOOTH HYDROPHILIC SURFACE AND HAVING DIAMETERS IN THE RANGE FROM 0.05 TO 5.5 MICRONS, THE AMOUNT OF METAL DEPOSITED UPON SAID COATED FIBERS BEING AT LEAST 5X10**6 GRAMS PER SQUARE CENTIMETER OF FIBER SURFACE, SAID COATED FIBERS BEING UNIFORMLY DISTRIBUTED THOUGHOUT THE SHEET IN AN AMOUNT EQUAL TO AT LEAST 0.3% BY WEIGHT OF SAID SHEET.
Claim 2
Dependent Claim
85 words
AN ELECTRICALLY CONDUCTIVE PAPER FORMED OF A MAJOR PROPORTION OF UNCOATED NON-CONDUCTIVE FIBERS AND A MINOR PROPORTION OF ELECTRICALLY CONDUCTIVE METAL-COATED FIBERS COMPOSED OF CHEMICALLY INERT MATERIAL AVING A SMOOTH HYDROPHILIC SURFACE AND HAVING DIAMETERS IN THE RANGE FROM 0.05 TO 5.5 MICRONS, THE AMOUNT OF METAL DEPOSITED UPON SAID COATED FIBERS BEING AT LEAST 5X10**6 GRAMS PER SQUARE CENTIMETER OF FIBER SURFACE, SAID COATED FIBERS BEING UNIFORMLY DISTRIBUTED THOUGHOUT THE SHEET IN AN AMOUNT EQUAL TO AT LEAST 0.3% BY WEIGHT OF SAID SHEET.
Claim 3
Independent Claim
140 words
A METHOD OF MAKING AN ELECTRICALLY CONDUCTIVE PAPER WHICH CONSISTS IN PROVIDING A MAIN MASS OF NON-CONDUCTIVE PAPER-MAKING FIBERS, SEPARATELY PROVIDING OTHER FIBERS COMPOSED OF A CHEMICALLY INERT MATERIAL HAVING A SMOOTH HYDROPHILIC SURFACE AND HAVING DIAMETERS IN THE RANGE FROM 0.05 TO 5.5 MICRONS, COATING SAID OTHER FIBERS WITH A METAL HAVING ELECTRIC CONDUCTIVITY SOAS TO MAKE THE FIBERS ELECTRICALLY CONDUCTIVE, SAID METAL BEING DEPOSITED ON THE FIBERS TO THE EXTENT OF AT LEAST 5X10**6 GRAMS THEREOF PER SQUARE CENTIMETER OF FIBER SURFACE, FORMING AN AQUEOUS SLURRY CONTAINING A MIXTURE OF SAID MAIN MASS OF FIBERS AND SAID COATED FIBERS, AND CONVERTING SAID SLURRY INTO A PAPER SHEET IN WHICH THE COATED FIBERS ARE UNIFORMLY DISTRIBUTED, THE COATED FIBERS BEING EMPLOYED IN AN AMOUNT SUFFICIENT TO PROVIDE AT LEAST 0.3% BY WEIGHT OF SAID COATED FIBERS IN SAID SHEET.
Claim 4
Independent Claim
140 words
A METHOD OF MAKING AN ELECTRICALLY CONDUCTIVE PAPER WHICH CONSISTS IN PROVIDING A MAIN MASS OF NON-CONDUCTIVE PAPER-MAKING FIBERS, SEPARATELY PROVIDING OTHER FIBERS COMPOSED OF A CHEMICALLY INERT MATERIAL HAVING A SMOOTH HYDROPHILIC SURFACE AND HAVING DIAMETERS IN THE RANGE FROM 0.05 TO 5.5 MICRONS, COATING SAID OTHER FIBERS WITH A METAL HAVING ELECTRIC CONDUCTIVITY SOAS TO MAKE THE FIBERS ELECTRICALLY CONDUCTIVE, SAID METAL BEING DEPOSITED ON THE FIBERS TO THE EXTENT OF AT LEAST 5X10**6 GRAMS THEREOF PER SQUARE CENTIMETER OF FIBER SURFACE, FORMING AN AQUEOUS SLURRY CONTAINING A MIXTURE OF SAID MAIN MASS OF FIBERS AND SAID COATED FIBERS, AND CONVERTING SAID SLURRY INTO A PAPER SHEET IN WHICH THE COATED FIBERS ARE UNIFORMLY DISTRIBUTED, THE COATED FIBERS BEING EMPLOYED IN AN AMOUNT SUFFICIENT TO PROVIDE AT LEAST 0.3% BY WEIGHT OF SAID COATED FIBERS IN SAID SHEET.
