  • Grinding process and unit, and corresponding production process of a hydraulic binder
    Patent number: 9114401
    Abstract: A grinding process, in a grinding unit including a first shop including a first mill and a first separator, an outlet from the first mill being connected to an inlet of the first separator; a second shop including a second separator and a second mill, an outlet from the second separator being connected to an inlet of the second mill; the second separator being fed by the material coming from the first separator, wherein the first separator is operated at a tangential speed of 15 to 25 m/s and a radial speed of 3.5 to 5 m/s; and the second separator is operated at a tangential speed of 20 to 50 m/s and a radial speed of 2.5 to 4 m/s.

  • Device for quick frequency tuning of a microwave tube using a direct sensing means
    Patent number: 6163112
    Abstract: A frequency tuning device for a microwave tube. The tube has one or more resonant cavities which are tuned with the aid of a movable tuning element for each cavity. Each tuning element has an actuating device and a sensor which detects the position of the tuning element. An electronic control is provided for comparing the position of the tuning element supplied by the sensor with a set position and for delivering a control signal to the actuating device which moves the tuning element to the set position.
