Abstract
New British cameras for high-speed cinematography are described, among which are included those designed by Marley1 and by Brailsford and Shrubb.2 The principles of a new Kerr-cell electro-optical shutter which can be used for cinematography are outlined, together with details of its performance. New light sources for high-speed cinematography include mercury-vapor lamps run at high current densities, and foil-filled flashbulbs fired in rapid succession. Several applications of high-speed cinematography are described showing how the solutions to engineering problems have been obtained when the parts concerned are in rapid motion, especially when the amplitudes of the movements are too small to resolve easily in a normal record. The vibration characteristics of the anvil of an 8-ton drop-forging hammer were determined by the use of a special optical, system attached to the anvil. Because of the widespread disturbance caused by the hammer blow, an artificially fixed point in space for reference purposes Was arranged by means of a long-period damped pendulum system bearing a fiducial indicator. The surface characteristics of white-hot steel bars were studied during high-speed rolling by means of high-speed cinematography using ultraviolet light.
