Summary

[edit]
Description
English: In 1903, the instrument builder Alfred Wehrsen patented a disk for influence machines that had internal sectors accessed trough buttons in the face of the disk. This disk was used in the machines described by Wommelsdorf in 1908 and built by Wehrsen. Most of the machines described there were Voss-type machines with just one rotating disk, but machines with two disks turning in opposite directions were also mentioned. Disks with embedded sectors, built with a different technique, were used also previously in other machines, as the ones described by Pidgeon. By Dr. Antônio Carlos M. de Queiroz (in memoriam).
