摘要： A viscometer for measuring liquid viscosities based upon rotational deflections of a suspended bob. The viscometer comprises a deflection indicator, a deflection reader located at a spaced relative position with respect to the indicator, a rotating element which rotates in unison with the bob and includes either the deflection indicator or the deflection reader, and a magnetic bearing assembly which prevents any substantial change in the spaced, relative position of the deflection reader with respect to the deflection indicator.

摘要： Physical property of a liquid sample to include a viscometric and/or rheological property if not a structural property such as gelation and/or crystallization can be determined with a rotating viscometer employed in a Scanning Brookfield technique. The viscometer and technique employ a Brookfield-type head having a high torque capacity. Low temperatures may be employed in the scan. For example, properties of a motor oil having a very high viscosity and/or a gelation point owing to its intrinsic properties, oxidation and/or sooting and so on, can be accurately, precisely, rapidly, and repeatably determined.

摘要： A rotary viscometer has a measuring motor which drives a measuring shaft that carries a disc mounted in an air bearing of a stator. The viscometer has a normal force measuring drive defined by at least one position sensor for determinal movements of the measuring shaft on the basis of viscoelastic properties of the substance to be investigated, such as a liquid. To measure the normal force in the region of the air bearing, the position sensors are disposed in the region of the air bearing on the stator, and in particular they are embedded in the stator and absorb the movements of the disc in the axial direction of the measuring shaft with resect to the stator.

摘要： A device and a method for testing a viscosified fluid containing particulate indicate when the particulate is in suspension within the fluid and when it is not. The device and method stir the fluid and particulate mixture for a time during which the viscosity of the fluid changes such that during a first period of the stirring time substantially all the particulate remains suspended in the fluid and during a second period of the stirring time substantially all the particulate settles out of suspension in the fluid. A signal is generated during the first and second periods such that the signal has a characteristic that changes from the first period to the second period to indicate the change in particle carrying ability of the fluid. Other characteristics, including crosslinking time, can also be determined. A test chamber includes interacting projections extending from the inner surface of a cup receiving the fluid and from an axial support extending into the fluid in the cup.

摘要： An acoustic viscometer and method for determining both the kinematic viscosity and the intrinsic viscosity of a liquid which includes an acoustic wave generator, a transmitting piezoelectric transducer, a receiving piezoelectric transducer, and a phase-shift detector. The transmitting piezoelectric transducer is positioned so as to be in contact with the liquid and is operably connected to the acoustic wave generator. The transmitting piezoelectric transducer propagates a longitudinal wave of known frequency through the liquid. The receiving piezoelectric transducer is spaced apart from the transmitting piezoelectric transducer and detects the longitudinal wave and a corresponding shear wave propagated through the liquid. The phase-shift detector is operably connected to both the transmitting and receiving piezoelectric transducers and measures the difference in phase between the longitudinal wave propagated by the transmitting piezoelectric transducer and the longitudinal and shear wave detected by the receiving piezoelectric transducer. The difference in phase is used to determine the velocity of the shear wave, and the kinematic and intrinsic viscosities of the liquid in terms of liquid density.

摘要： Slurry useful for wire-saw slicing has viscosity adjusted to 400-700 mPa·second at a shear speed of 2/second and of 50-300 mPa·second at a shear speed of 380/second. The viscosity of slurry is measured using a cone and plate type viscometer which can measure viscosity at different shear speeds. Since the slurry sufficiently flows into inner parts of grooves formed in an ingot and consumed for wire-saw slicing due to the viscosity controlled in response to the shear speed, the ingot can be efficiently sliced to wafers or discs.

摘要： In a method for the determination of the viscosity (&eegr;) of a liquid, e.g. of blood, which is forwarded by a pump, e.g. a blood pump, said pump having a rotor for the forwarding of the liquid from the inlet of the pump to the outlet, the rotor is used for the determination of the viscosity (&eegr;). For the determination of the viscosity (&eegr;) of the liquid no spatial deflection of the rotor from its operating position takes place, but rather the rotor is left in its operating position and the viscosity (&eegr;) is determined from measurement parameters of the pump or of the rotor respectively.

摘要： A rotary rheometer has a measurement motor (1) rotating a measuring shaft (16) on which an upper, and in particular a plate-shaped or conical, measuring part (4) is fastened. A measuring gap (S) is formed between the first measuring part (4) and a rotationally fixed lower, preferably plate-shaped measuring part (5). The substance (12)—in particular fluid, gel, or the like—to be tested is introduced into the measuring gap (S). The width of the measuring gap (S) can be adjusted by displacing the two measuring parts (4, 5) relative to each other. A heating or tempering unit for the lower measuring part (5) is arranged below the lower measuring part (5). To heat or cool or temper the upper measuring part (4) at least one heat pump (24), and in particular at least one Peltier block, is provided by which heat can be supplied to or removed from the upper measuring part (4).
