Abstract: The “Research Laboratory” referred to above consists of 105 theaters in the Posts and Stations of the Army, presenting the widest variety of projection problems ever assembled under one management. When the U. S. Army Motion Picture Service was organized for the purpose of operating these theaters on a centralized and business like basis, it became the task of that service to solve these varied problems. The unit which I am about to describe to you is one of the things which had to be developed before these problems could be solved. This unit is now in use in practically every Post and Station of the Army in the continental United States and Panama. Altho many are equipped with earlier types than the one here illustrated, the basic principles are the same.
