Abstract
Experiments were conducted to record cathode rays of low voltage on a film. This was carried out by means of a specially constructed vacuum tube, the film passing over a slit in the anode which formed part of the outside of the tube. It was hoped that this would provide a means of sound recording when the tube was properly modulated. Problems concerning the making of the slit, the maintenance of a suitable vacuum, a filament which would give a good emission at working pressure, and the proper designs for the tube elements were considered.
