Abstract: A microprocessor-controlled system of aerial transport for industrial installations. This system is characterized by the combination of the following parts: (a) a main circuit, (b) a group of carts, (c) stations, (d) a group of points, (e) an ascent group, (f) identification readers, (g) control cards and (h) central unit, and, furthermore, the main circuit is composed of a structure of tracks and carrier columns, over which tracks the group of carts may travel; the carts are able to have access to the stations through the action of the points, and the central unit is based on a microcomputer which knows and controls the evolution of the system by directing its operation according to a predetermined programming, changeable at any time, and making decisions according to criteria with which it has been programmed, all of the operations being a function of the information which is supplied to the microcomputer by the control cards and the group of identification readers.

Abstract: A machine for continuously laterally perforating very wide paper and having an electronic control for smoothly starting and stopping the paper, a length of perforated paper detection device and combined control warning device for detecting the end of the roll of paper, wherein the machine is arranged in a compact structure having two simultaneously mechanized lateral holders which support all of the various mechanisms so as to thereby ensure the perfect positioning thereof. The actuation of the perforator heads of the machine is effected by the paper itself through a precision mechanized antiskid roller and the tension of the paper is controlled by swinging rollers whose movement is detected by a sensor and electronically processed while simultaneously taking into consideration the speed of the paper so as to control the unwinding of the feed roll of paper utilizing an electromagnet brake.
