572 BERKLEY AND MANSBERG November and the lens to be two focal lengths from the cathode-ray tube. This results in an over-all distance of 24 inches of the camera film from the cathode-ray-tube face. This long distance results in an awkward assembly of equipment. For these reasons, most oscillographic cameras have chosen the 35-mm film. Where continuous-motion recordings are to be made at high speed and the film is to be brought up to speed quickly, the inertia represented by the mass of even 100 feet of film becomes considerable and Fig. 25 — Avimo drum camera. the rapid acceleration or deceleration required may result in breakage of the film. For this reason, in the Fastax camera, it is more desirable to use 16-mm film because of its lower inertia. In some cases it is only possible to attain required speeds without loss of film by use of a drum camera in which a continuous loop of film is brought up to speed and the transient then displayed on the face of the cathode-ray tube. A somewhat similar condition can be obtained in the use of a continuous-motion camera by loading a continuous loop and running the camera at its highest speed. This is of some advantage also in the measurement of random phenomena where one desires to conserve film. Figs. 23 and 24 show some typical cameras designed for
