410 i: IN JO A I A TOG R APHIC AN N UAL The Mitchell Silent Camera The Radio Corporation of America has announced the perfection of a silent 48 cycle camera motor which eliminates the necessity of gears between the motor and camera. This firm has also announced a 720 r.p.m. silent camera motor for use on the Bell & Howell and the Fearless cameras. Another camera has been designed by Huguenard and Magnan, employing four lenses and taking twelve pictures in an area the size of a standard 25 mm. frame. With a linear velocity of the film equal to 3 meters per second, 2400 pictures may be exposed per second. In the field of studio illumination, the most outstanding development in the past year has been the production of silicon aluminum housings, designed particularly to eliminate the objectionable noises commonly given off by the older sheet-iron housings when a lamp is warming up. Both Mole-Richardson, Inc., and the Lakin Company adopted the aluminum housings.
