Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
122 words
IN A SYSTEM FOR GAGING THE QUANTITY OF A STORED FLUID, A SEALED HOUSING, A FLUID-STORAGE BLADDER LOCATED WITHIN SAID HOUSING, MEANS FOR SECURING SAID BLADDER TO SAID HOUSING AT A PLURALITY OF SPACED POSITIONS ALONG THE INNER SURFACE OF SAID HOUSING, ELECTRICALLY CONDUCTIVE MEANS IN AREA CONTACT WITH DISCRETE PORTIONS OF SAID BLADDER SPACED FROM AND LYING BETWEEN SAID POSITIONS AT WHICH THE BLADDER CONTACTS THE HOUSING, AND AT LEAST ONE PAIR OF CONDUCTIVE LEADS CONNECTED TO SEPARATE CONDUCTIVE PORTIONS OF SAID BADDER LYING ON OPPOSITE SIDES OF A MEDIAN PLANE OF SAID BLADDER, THE CONDUCTIVE PORTIONS ON SAID OPPOSITE SIDES CONSTITUTING THE PLATES OF A CAPACITOR, THE CAPACITANCE OF WHICH IS DEPENDENT ON THE QUANTITY OF FLUID IN SAID BLADDER.
