  • Sealing device for explosion-proof motors
    Patent number: 6264204
    Abstract: A sealing device for explosion-proof motors, the particularity of which is the fact that it comprises a first element which is coupled to the motor casing and a second element which is coupled to the driving shaft through rolling means; the first and second elements are mutually coupled through elastic elements to allow their relative movement.

  • Pressure measuring membrane with resonant element vibrating orthogonal to membrane movement
    Patent number: 5969257
    Abstract: An improved device for measuring pressures, comprising a silicon membrane or diaphragm which is exposed, on its two faces, to two pressures whose difference is to be measured. A resonant element is provided on one face of the diaphragm, which is treated by selective chemical etching, and is mechanically coupled to the diaphragm so that its resonance frequency varies as a consequence of the deformation undergone by the diaphragm.
