Abstract: A collecting system which may be used for a display cabinet, including an elongated frame at a first extremity or entrance of which are deposited packages which are to be removed from the other extremity or exit. The frame has a profiled shape, comprising two upper horizontal parts on which the packages are deposited and a lower horizontal runway in between, on which lower runway runs an automotive carriage comprising automatic electro-mechanical means comprising cooperating carrier rollers raising any package and carrying it to the exit.

Abstract: The circuits comprise a first part located at a control station where the trolley lies when not operated, and a second part located on the trolley. The first part comprises a three phase power circuit and a control circuit for the trolley. The connection between two parts is effected by only three active conductors, although the power supply is of the three phase type, the control signals being transferred to the second part when only two of the three phase conductors are coupled to the second part. To this end, a time lag contact controlled by a relay of said control circuit is inserted in the coupling of one of the three conductors and the circuit of the second part includes a memory relay which is energized by means of the two other conductors and which is no longer energized when the third phase is applied to the second part.
