16mm Projector for Full-Storage Operation with an Iconoscope Television Camera
A heavy-duty 16mm projector was described in 1950 by the author.1 This projector has since been modified to adapt it to full-storage operation with a television camera. The modifications include a somewhat faster pulldown operating at the uniform rate of 24 frames/sec and a relay condenser system which, in combination with a special shutter and filters, provides adequate illumination of improved quality within blanking time. Operational facilities are also described. The accommodation problem of converting 24 frames/sec of motion pictures into 30 frames/sec for television is treated in an Appendix to the paper.
