Special Control Equipment for the Fastax Camera

Abstract

The problem of timing complex events in relation to the short taking period of a high-speed cine camera is discussed, and a flexible programming assembly capable of initiating and ending six events in any sequence in close relation to the film run in the camera described. In conjunction with this, a stepless accelerator unit is used which allows high rates of acceleration without excessive strain in the camera drive and film transport mechanism. Although application described is a specialized one, combustion in a diesel engine, the system is capable of wider and more general application to many cases of high-speed cinematography.
