  • Patent number: 6599049
    Abstract: An indicating instrument (4) has a housing (3) having an external thread (7) by which it can be inserted in a recess (2) of a dashboard (1). A housing nut (9) which can be screwed onto the external thread (7) and has an internal thread (8) fixes the housing (3) on the dashboard. Either the external thread (7) and the internal thread (8) are provided only in at least two subregions of the circumference of the housing (3) and of the housing nut (9), respectively, the subregions each having a shorter length than the subregions which lie between them and do not have a thread, so that the housing nut (9) can be pushed in at least one angular position completely onto the housing (3) without engaging in the external thread (7), or instead only the external thread (7) or the internal thread (8) is provided in at least two subregions of the circumference, which subregions are of resilient design radially, so that the internal thread (8) and external thread (7) can become disengaged.

  • Patent number: 6595239
    Abstract: In a feed device with a filling-level sensor fastened to a wall of a baffle, the filling-level sensor has a lever wire for holding a float. A carrier for mounting the filling-level sensor to a wall of the baffle is connectable to the wall in at least two different orientations. The pivoting range of the float is set by the selected orientation of the carrier on the wall. The feed device is consequently suitable for use in differently constructed fuel tanks.

  • Patent number: 6588270
    Abstract: Filling level indicators for washer fluid containers in motor vehicles have hitherto been arranged directly on the washer fluid container or been integrated in the instrument cluster on the motor vehicle. Despite the available information, the filling of the container when the level is too low is often delayed. A filling level indicator more effectively indicates the filling level by arranging the filling level indicator in the region of the tank filler neck, whereby the filling level in the washer fluid container is only indicated to the driver when he has in any case interrupted his journey in order to fill up with fuel and is free from other activities, so that it is virtually impossible for him to be distracted.

  • Patent number: 6588924
    Abstract: In a display unit there is provided a front instrument panel (2) for inscription with symbols (9), which have an opaque portion (12) enclosed by a transparent portion (11), a so-called island. This opaque portion (12) is applied to a transparent backing (15) and fitted into an opening (13), made in the front instrument panel (2) to correspond to the contour of the symbol (9), at a distance from an edge region (20) of the opening (13). Use of the backing (15) makes it possible to dispense with connecting cross-pieces between the island and the front instrument panel (2). Furthermore, a process for producing the front instrument panel (2) intended for the display unit is provided, in which process firstly the opening (13) is made by punching and the backing (15) is formed by film-insert molding a transparent plastic behind the front instrument panel (2).

  • Patent number: 6584792
    Abstract: In a method for driving an output stage by pulse-width modulation, which driving serves to supply a unit cooling the output stage during operation, at a higher temperature of the output stage a style of driving is performed which results in a low power loss in the output stage. At a lower temperature of the output stage driving is performed in such a way that the power loss is higher.

  • Patent number: 6578417
    Abstract: A filling level sensor for a liquid container such as a fuel tank for a motor vehicle includes a lever arm having a first end on which a float is mounted and a second end mounted in a support part. A contactless magnetic sensor and a magnetic device are arranged so that the magnetic device moves in response to a deflection of the lever arm due to a change in fill level in the tank and the movement of the magnetic device changes a magnetic field acting on the magnetic sensor so that the magnetic sensor supplies an output signal corresponding to the filling level in the fuel container.
