Abstract: A device for a window lifter of a vehicle door includes a cable winding drum disposed inside a housing of a casing and a seal attached to the casing. The seal includes a stop portion that prevents translational movement of the drum along its rotational axis while still allowing the drum to rotate freely about the axis. The inventive device allows the drum to be held in the housing before the casing is mounted on a dividing panel without requiring auxiliary parts to hold the drum in place and without compromising the seal when the casing is fastened to or removed from the dividing panel.

Abstract: Measuring the electrical resistance of a resistive body, in particular a reservoir containing a printing product such as ink. According to the invention, the resistive body is used to define a capacitance arrangement formed from a capacitive branch which includes a capacitor electrically connected to the resistive body and this is incorporated in a resonant circuit that includes a variable capacitor. The resonant circuit is supplied with a fixed frequency, and as the capacitance of the variable capacitor is varied the peak of the signal is sought. The amplitude of the peak is representative of the resistance of the resistive body.
