Abstract: The short effective taking time of a high-speed cine camera, such as the Fastax, demands accurate synchronization of events necessary to initiate and control the phenomenon being photographed. The equipment described enables up to six events to be controlled for sequence and duration in accurate relation to the camera film run. Automatic telephone techniques and components are employed and the sequences are set up on a ring-and-socket board. A stepless accelerator is provided for the camera motors allowing high rates of acceleration in relation to stress on the film. The case under consideration is the photography of injection and combustion phenomena in a compression ignition engine; but the equipment is flexible and can be applied to other problems and can control more events or longer periods by appropriate design modifications. An ancillary technique is also described for converting half-frame-height 16mm records to standard 16mm format and stretching, by frame repetition, of vital sequences in a film if required.
