Data display system

Claim 1

Data display system having a group of at least two parallel rotors (101 to 104) each formed by a single body (2), having in two diametrically opposite areas ranges of different colors, which rotates freely in a mounting (5) to which it is associated by a shaft (4), which is in contrast interlocking in rotation with a permanent magnet (6) the position of which is such that the line passing through its poles (7, 8) is essentially radial to the axis of the shaft (4), in which system end rotors (101, 104) of the group of at least two parallel rotors, to control their rotation, each cooperate with one pole of an electromagnet (10) connected to a source (15) of direct current by an inverter-interruptor (16) and which is attached to the mounting (5) in such a way that each pole is located in the plane perpendicular to the axis of the rotors in which the poles of the permanent magnets may turn, and in said system the datum to be displayed, such as a sign, a letter, a figure or a design, consist of at least one point the entire apparent surface of which is always of one color, for example light, or of another, for example dark, this point is itself formed of several colored ranges which are juxtaposed and borne by distinct ones of the group of rotors (101, 102, 103, 104) grouped to be controlled synchronously and, so that all the rotors of the same group may be activated at the same time, the system includes a single electromagnet (10) having poles (17, 18) located in the plane of the axes of the rotors, on either side of the entire group of rotors so as to directly exert their effect only on the permanent magnets (6) of the rotors (101, 104) located at the ends of the group and only on their pole oriented towards the outside of the group.
