Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
95 words
A METHOD OF MANUFACTURING CAPACITORS WHOSE VALUES OF CAPACITANCE ARE MAINTAINED WITHIN A NARROW LATITUDE OF THE VARIATION FROM A STATED CAPACITANCE, WHICH INCLUDES THE STEPS OF DEPOSITING A WOUND CAPACITOR SECTION IN AN ENCLOSURE TOGETHER WITH AN INFLATABLE DEVICE ARRANGED TO APPLY PRESSURE TO SAID WOUND CAPACITOR SECTION TRANSVERSE TO THE CONVOLUTIONS THEREOF, EVACUATING AND THEN IMPREGNATING THE CAPACITOR SECTION AND THE SPACE WITHIN THE ENCLOSURE WITH A DIELECTRIC FLUID, FORCING FLUID INTO SAID INFLATABLE DEVICE WHILE MEASURING THE CAPACITANCE OF THE CAPACITOR SECTION, AND SEALING THE INFLATED DEVICE TO RETAIN ITS PRESSURE FILLING.

Claim 3
Dependent Claim
78 words
AN ELECTRICAL CAPACITOR INCLUDING AN ENCLOSURE, A CAPACITOR SECTION IN SAID ENCLOSURE HAVING MULTIPLE LAYERS COMPRISING CONDUCTIVE METALLIC ELECTRODE MUTUALLY SEPARATED BY INTERPOSED DIELECTRIC LAYERS, AND MEANS FOR MAINTAINING THE CAPACITANCE OF SAID CAPACITOR SECTION AT AN ESTABLISHED VALUE INCLUDING AN ELASTIC-WALLED DEVICE FILLED WITH FLUID UNDER PRESSURE FOR MAINTAINING PRESSURE AGAINST SAID CAPACITOR SECTION TRANSVERSE TO SAID LAYERS THEREOF, SAID INFLATABLE DEVICE HAVING A CLOSED FILLING PORT THAT IS AT LEAST INITIALLY ACCESSIBLE EXTERNALLY OF SAID ENCLOSURE.
