Latest Patents
Portier's latest patents include a method for measuring stresses or forces and axial and annular magneto-elastic dynamometers. The method for measuring stresses or forces involves the measurement of variations in the magnetic properties of ferromagnetic substances under stress conditions. This process is executed by placing a ring of ferromagnetic material between two parallel faces where stresses are applied. The ring defines a magnetic circuit, and an electric coil is positioned within and around the ring. By passing a current through the coil, changes in the properties of the current are measured to determine variations in the magnetic properties of the ring. The axial and annular magneto-elastic dynamometers utilize a similar approach for measuring stresses or forces.
