Character or symbol display equipment for motor vehicle - forms air gap for magnetic field holding dust particles forming identification antitheft code

摘要

The device described is for vehicles, in particular public vehicles or motor cars. On the inner side of the outer skin (1) an arrangement is fitted consisting of a soft iron core (4) and a permanent magnet or electromagnet (5), mounted between retaining plates (3) to form an air gap in the form of the sign or symbol to be shown. Plastics material is provided to reduce the entrance of material since, in the air gap it will be obvious dust particles from the surrounding air quickly collect and stick, held by the magnetic field. USE/ADVANTAGE - Permanent display for advertising or information purposes enduring after cleaning or even painting. Enables stolen vehicle to be identified.
