The machine for the sorting by size of pear-shaped objects comprises a conveyor able to move essentially horizontally and comprising a first alignment of equidistant and parallel primary rollers separated each from the next by an interval allowing one object to pass through. Each delay cell can advantageously provide both delay and duty cycle correction functionality. The slip linkage includes a first stage that converts the reciprocal motion of the drive arm into rotational motion and a second stage that selectively engages the a drive shaft of the generator drive to impart the rotational motion thereto. Moreover, the biasing circuit, the inverter chain stage, and the amplifier stage can be connected to a power down circuit which, when the translator is not being used, will ensure various circuitry of the translator will not consume extensive power.
