Claim 3
Independent Claim
81 words
AN APPARATUS FOR MEASURING THE APPARENT BULK MODULUS OF A TRANSIENT-ELECTRIC-POTENTIAL-RESPONSIVE FLUID COMPRISING A RECEPTACLE FOR A CONSTANT-TEMPERATURE FLUID BATH, THERMO-REGULATOR MEANS FOR MAINTAINING A CONSTANT TEMPERATURE IN SAID RECEPTACLE, VISCOMETER MEANS INCLUDING UPPER AND LOWER VESSELS SUPPORTED WITHIN SAID RECEPTACLE, A RELATIVELY THIN-WALLED CONDUIT FABRICATED OF HIGH-RESISTIVITY MATERIAL CONNECTING SAID VESSELS, A PAIR OF ELECTRODES DISPOSED ADJACENT TO SAID CONDUIT EXTERNALLY THEREOF, MEANS FOR APPLYING A TRANSIENT ELECTRIC POTENTIAL TO SAID ELECTRODES, AND LIQUID-LEVEL INDICIA ASSOCIATED WITH ONE SAID VESSEL.
