A new conveyor for geometric and technical applications, essentially characterized by the fact that its circle, of any material, wood, metal, artificial resin or other, has printed or engraved ten circular crowns, in which, from the center and by correlative order, they have in themselves, the first, a graduation in minutes, the second the sexagesimal degrees, the third the centesimal grades, the fourth and fifth trigonometric values, the sixth the epigraphs by quadrants, the breasts, cosines, tangents and Cotangents and the four remaining crowns bear the figures corresponding to the divisions of the prime numbers, comprising at their center a coupling and rotation arrangement that can be fixed properly, in which the axis of rotation is a nucleus arranged in the center of the disc and the other piece is a crown fit into it belonging to a rule whose ends protrude from the disc and this rule presents at equal distances of the ntro, two prolongations in arc or bulls, one on the upper part and another lower the lower part, which fall on the fourth and fifth crowns, in the extension of a quadrant, these bulls comprising graduations in radians at 30º and the ruler, in its left part another in radians for another 30º.
