  • Patent number: 4818926
    Abstract: A tachometric device is provided with a D.C. electric motor a shaft of which drives a pair of permanent magnets to rotate. A first permanent magnet controls a speed indicator unit; a second permanent magnet is rotatably mounted within a winding the terminals of which are connected to a negative feed back circuit for controlling the speed of the motor.

  • Patent number: 4815322
    Abstract: A speed indicator device for vehicles is described, of the type in which the speed indication is given over a scale by an index fitted to an oscillating element drawn for example, by a permanent magnet carried into rotation by the shaft of an electric motor. The device comprises a bush on one side fixed to the magnet and on the other fixed, by a spring, to the shaft of the electric motor.

  • Patent number: 4811603
    Abstract: A tachometric generator comprises an input shaft which can be connected to a drive take-off from the vehicle, a main shaft connected to this input shaft by means of a ball joint resilient coupling torsionally coupled to an output shaft which can be connected to an external mechanical transmission. The speed of rotation of these shafts is detected by a magneto-electric sensor facing a magnetic disc fitted onto the output shaft.

  • Patent number: 4801926
    Abstract: The device is of the type comprising a magnet carried by a float and a magnetically actuable electric contact carried by a support element which also performs the function of guarding the float. The most important characteristic of the device is that of providing positioning means which maintain the float constantly centered with respect to the support element during excursions of this latter caused by the hydrostatic thrust exerted by the liquid.

  • Patent number: 4726002
    Abstract: A dashboard clock in which a liquid crystal plate for display on a front face, a light source and a controlling electronic circuit are structured in such a way that an opening permits direct illumination and heating of the plate by means of the light source while reducing the length of the connections between the plate and the electronic circuit.Such a clock is conveniently utilized, for example, on board motor vehicles.
