Abstract
The tracing element is carried by one vertex of an articulated parallelogram, of which the arms are constituted by thin steel or glass fibres associated with a plastics coating or matrix for damping vibrations. The arms are moved by servocontrols constituted by electromagnets with moving coils having a length less than the length of the corresponding magnet pole piece. The coils are formed from a conductor of square or rectangular cross-section in order to provide maximum packing for the turns.
