  • Patent number: 6351435
    Abstract: A display having at least one hand which can be driven by an electric drive, it being possible for the hand or the hands to execute rotations of more than 360° in a first direction, wherein it is provided that the hand or the hands (Z) can be rotated in a second direction (CCW) which is counter to the first direction (CW), that the hand or one of the hands (Z) can be rotated in the second direction(CCW) only up to a certain position (P) and, in this position, assumes a reference position, and that there is a detecting device (V) which detects the inability of the hand (Z) to rotate further in the second direction (CCW).

  • Patent number: 4562395
    Abstract: A damped stepping motor (1) for the driving of a measuring mechanism is acted on with approximately rectangular pulses by a control circuit arrangement having at least one amplifier (amplifier-transistor 5) as controlled switch. These pulses are obtained from measurement pulses. For the damping of the noise of the stepping motor and the measuring mechanism connected with it via a transmission, the amplifier forming the controlled switch is connected by a delay of the first order (capacitor 9, series resistor 10), so that the edges of the pulses fed into one coil are rounded.
