摘要： A MEASURING SYSTEM FOR AN ANALYTICAL CENTRIFUGE HAVING A ROTOR WITH TWO RO MORE PREFERABLY SWINGING SEDIMENTATION CELLS TO BE SCANNED BY LIGHT PASSAGE. THE SCANNING MEANS HAS A PREFERABLY ADJUSTABLE AND PREFERABLY CURVED OPTICAL SLIT THROUGH WHICH THE LIGHT PASSES TO REACH THE ROTOR AND TRAVERSES A RADIALLY EXTENDING SLIT LOCATED IN FRONT OF EACH SEDIMENTATION CELL. A CATHODE RAY TUBE WITH A VERTICAL DEFLECTION SYSTEM HAS APPLIED THERETO SIGNALS GENERATED BY THE LIGHT BEAM PASSING THROUGH THE SEDIMENTATION CELLS. A SYNCHRONIZING MEANS CAUSES THE HORIZONTAL DEFLECTION IN THE CATHODE RAY TUBE ACCORDING TO THE LIGHT SCANNING OF EACH SEPARATE CELL DURING THE ROTATION OF THE ROTOR. TRIGGER MEANS HAS ONE OR MORE MEMBERS ROTATING WITH THE ROTOR COOPERATING WITH ONE OR MORE STATIONARY MEMBERS MAKING POSSIBLE SIMULTANEOUS OBSERVATION OR REGISTRATION OF THE MEASURING CURVE FOR TWO OR MORE ARBITRARILY CHOSEN SEDIMENTATION CELLS ON THE CATHODE RAY TUBE.
