  • Piezo-rheometric measuring cell and corresponding piezo-rheometer
    Patent number: 7784329
    Abstract: The invention relates to a piezo-rheometric measuring cell for shear or compression measurement, essentially comprising two sample holder plates, with the sample for analysis between the same in solid, liquid or intermediate form, piezoelectric ceramic elements on the faces of the plates opposite to the faces in contact with the sample and a construction forming the housing and compressing the arrangement of plates and ceramic elements, one or more ceramics called emitter, being connected to one of the two plates or the emitter plate and subjecting the same to shear or compression vibrations by means of an excitation signal and one or more ceramics, called receiver, being connected to the other plate or receiver plate and converting the forces to which the same is subject into a measured signal.

  • Noise-absorption structures and walls constituted thereby
    Patent number: 6332027
    Abstract: A noise-absorption structure comprising a frame over which a gastight membrane is tensioned, the outside face of the membrane receiving soundwaves, a gas such as air filling the volume defined by the frame and the membrane, and energy-dissipation means housed in the volume, which means are of the laminar gas-flow type, of the electrostatic type, or of the electromagnetic type, and area adjustable or controllable to modify the acoustic impedance of the structure as a function of the characteristics of the noise to be absorbed. The invention is particularly applicable in the aviation industry.
