Summary
[edit]DescriptionBig Wehrsen Machine (or a sectored Holtz machine) I.jpg |
English: In 1907 Heinrich Wommelsdorf described an electrostatic machine that was a variation of the Holtz machine of the first kind but with a rotating disk made of ebonite having embedded sectors accessed through buttons at the disk surface and inductor plates embedded in celluloid attached to a fixed ebonite disk. Machines with this structure were popularized by the instrument builder Alfred Wehrsen, in Berlin, who also patented this form of disk in 1903, so it is sometimes mentioned as the "Wehrsen machine". By Dr. Antônio Carlos M. de Queiroz (in memoriam).
