PATENT APPLICATION entitled: Process for determining the rheometric properties of materials and apparatus for carrying out said process. in the name of: Andr? KEPES ABSTRACT OF THE DISCLOSURE The present invention relates to a process for determining the rheological properties of fluid, consisting in completely filling a space located between a body constituted by a double cone of vertex angle 2.alpha.,.alpha. being smaller than 90° and a biconical surface, of the same axis as the axis of said double cone, of vertex angle 2 .beta., .beta. being equal to or smaller than 90°, then said material is subjected to strains by driving said double cone or said biconical surface around the common axis. The non-driven element remaining fixed, said drive being effected with the aid of a device by which either a speed or a torque is imposed, according to a known programme, on the driven element, and the parameter -speed or torque - which is not imposed is measured. The invention also relates to an apparatus for carrying out said process.
