A device is provided for grounding a metal vehicle body or the like, comprising an arrangement for automatically creating at desired times, between the body (1) and the ground (3), ions which, under the effect of the electric field which may exist between the body and the ground, are driven towards the body or towards the ground depending on their polarity and thus equalize the potentials of the body and the ground.

Devices for grounding vehicle bodies or similar

The invention relates to an electronic circuit for remote interrogation of a receiver through a two wire line and to detect the response signals emitted by this receiver. The circuit comprises means for comparing with a reference voltage the actual voltage defining said response signals. This reference voltage is a weighted variable voltage obtained by low band-pass filtering, in a resistance-capacity circuit, of said actual voltage.
