Abstract :
A new microfilm recorder has been designed by Bell and Howell Company, Chicago, 111., which photographs on 16-millimeter film important papers which are needed for records. The recorder automatically takes care of lens opening and shutter speed. Lighting and film rating are perfect, so the operator does not need to worry about them. Keeping the electricity under control is handled by a device made by the Sola Electric Company, also of Chicago.
