Abstract: The invention concerns a tamper-resistant and indelible method for marking objects, in particular labels, providing marking with good contrast and enhanced visibility. Said method is essentially characterised in that the marking is carried out in two operations: integral marking, i.e. in the thickness of the object; surface marking; said surface marking being superposed on the integral marking. The invention also concerns a marking label.

Abstract: The invention refers to a system for data display by means of magnetically controlled bistable rotors.It is characterized by the fact that this point is itself comprised of several colored ranges which are juxtaposed and borne by distinct rotors (101, 102, 103, 104) grouped to be controlled synchronously and by the fact that, so that all the rotors of the same group are activated at the same time, this system includes a single electromagnet (10) the poles (17, 18) of which are placed in the plane of the axes of the rotors on either side of this group of rotors so as to directly exert their effect only on the permanent magnets (6) of the rotors (101, 102, 103, 104) located at the ends of the group, and this exclusively on their pole oriented towards the outside of the group.Application to display of data which must be read at great distances.

Abstract: A sorter for pieces of money feed the pieces onto a rotating disk and the various sizes are separated and received by fingers entering grooves in the disk spaced from the disk rim such that the pieces overhang the grooves corresponding to the diameter of the piece. A sorting track on the disk is interrupted by the grooves and the portion of the track at an internal edge of a groove is higher than that portion of the track on the external edge of the groove.

Abstract: A device for sorting and separating coins has a track with an increasing width between the feed point for the coins and the exit point for the coins.

Abstract: A machine for handling pieces of money or similar articles has a fixed wall n which the pieces roll and the wall is extended by a rolling band extending over the circular path followed by the pieces to reduce the effective width of the path so that only a single piece can be supported by the path and other non-supported pieces fall by their weight into a central zone. The machine efficiently separates pieces the smallest of which have a diameter equal to one-half the diameter of the largest pieces.
