"IMPROVEMENTS INTRODUCED IN THE AUTOMATIC SPEED DRIVES", characterized essentially because it includes a mechanical differential that allows that the revolutions of a motor shaft can be distributed unequally between two others, coupling one of the latter to the transmission of the resistance to be overcome, and establishing in the other driven shaft of the differential the armature of a conventional electromagnetic element, producer of electrical energy, equivalent in power, to that of the driving motor.
