  • Patent number: 8549897
    Abstract: Disclosed herein is a system and method for screening a liquid composition. The system includes (a) a test cell having a top portion and a bottom portion, the test cell comprising (i) a test panel removably mounted to the top portion of the test cell at an angle of between about 10 to about 45 degrees to the horizontal of the test cell; (ii) a reservoir for holding the liquid composition; and (iii) a means for applying a substantially uniform coating of the liquid composition from the reservoir to at least a portion of the test panel; (b) a means for heating the test panel according to a first temperature control program; (c) a means for heating the reservoir according to a second temperature control program; and (d) a means for supplying an oxidizing gas to the test cell.

  • Patent number: 7752895
    Abstract: A method for determining the viscosity and relative change of viscosity of a fluid over plural shear rates caused by a decreasing or increasing pressure differential resulting from fluid flow to a defined chamber in a capillary system. The flow of liquid through the capillary restriction, the pressure variation rate and known dimensions of the system can be used typically by a processor to determine a rheological property of a fluid.
