  • Stamping and/or drilling device comprising a substrate support head with continuously controlled orientation
    Patent number: 9061462
    Abstract: A device for stamping and/or drilling a substrate, including two dies supported by two support assemblies configured to be moved relative to each other in translation. The assembly includes: a base; an orientable head fixed to the die; a connection mechanism between the base and the head to adjust orientation of the head relative to the base; pressure sensors configured to continuously output information about pressure applied at different points of the die; and a mechanism controlling a connection, to continuously control the orientation of the head relative to the base, in response to information output by the sensors.

  • Relaxation-type viscosimeter having a magnetic field generator and method therefor
    Patent number: 6988392
    Abstract: The process for measuring viscosity relies on the observation of the relaxation of a sample drop (A) initially flattened between two plates (7,8), normally without any contact with them due to a gas layer blown through their opposite faces (10, 11); one correlates the observed phenomenon with a relaxation model fitting each portion of the measurement curve so as to estimate concurrently the viscosity and the shear rate, then the sensitiveness of the viscosity to the shear rate by compiling the said portions. The proposed viscometer includes a variable magnetic field generator (16) to produce, using a removable screen (18), various stirring and shears in the sample (A).
