Method for the examination of the separation of suspensions and emulsions

Claim 1

AN APPARATUS FOR DETERMINING QUANTITIES OF PRESELECTED PARTICLES FRACTIONS IN LIQUID MIXTURES SUCH AS SUSPENSIONS AND EMULSIONS, COMPRISING A BALANCE WITH AN ARM, A RECEPTACLE SUITABLE FOR CONTAINING LIQUID MIXTURES, AS FEELER BODY SUSPENDED ON SAID ARM OF SIAD BALANCE AND DISPOSED IN SAID RECEPTACLE SO AS TO REPOND TO WEIGHT AND SPECIFIC WEIGHT VARIATIONS DUE TO SEPARATION OF SOLID PARTICLES FROM SAID LIQUID MIXTURE, A MAGNETIC SYSTEM COMPRISING A PERMANENT MAGNET ELEMENT AND COIL ELEMENT, ONE OF SAID ELEMENTS BEING CONNECTED TO SAID ARM, A TRANSFORMER CONNECTED TO THE OUTPUT OF SAID COIL ELEMENT FOR DIFFERENTIATING OUTPUT SIGNALS OF SAID MAGNETIC SYSTEM EXCITED BY MOVEMENTS OF SAID BALANCE ARM CAUSED BY WEIGHT AND SPECIFIC WEIGHT VARAITIONS OF SAID LIQUID MIXTURE, AND MEANS FOR SIMULTANEOUSLY REGISTERING SAID MOVEMENTS OF SAID BALANCE ARM AND SAID OUTPUT SIGNALS OF SAID MAGNETIC SYSTEM AND OUTPUT SIGNALS OF SAID TRANSFORMER.
