  • Process for measuring using standard blocks and a standard measuring block
    Patent number: 4351114
    Abstract: Standard block comprising an element (L) kept in vibration by means of the motor (M). As soon as an object comes into mechanical contact with the measuring surface (C), the flexible-part (F) gives very slightly allowing the regulating screw (Vi) to disturb the free oscillations of the element (L). The detector (E) detects this disturbance and signals the moment of mechanical contact by means of the lamp (La) for example. The standard block allows precise measurements to be taken by announcing the moment of contact, without the measurement precision being influenced by the contact pressure.
