REPORT OF THE PROJECTION PRACTICE COMMITTEE*
Summary. — A brief account of the work of the Committee during the past year, in which is traced the evolution of the SMPE Projection Room plans and their general adoption by the industry. Work is being initiated by the SubCommittee on Theater Structures in a study of the disparity that exists among various state and municipal motion picture regulations. The subject of heating projection rooms is also reported upon by the Sub-Committee on Fire Hazards. Work has been begun by the SubCommittee on the Power Survey in determining the average or representative operating conditions, with particular respect to the power consumed, in theaters of various seating capacities and equipped with various types of projection apparatus.
During the past year, the Committee has undertaken and successfully brought to fruition several major projects of outstanding importance to the technologic groups of the motion picture industry. Moreover, the Committee is gratified to note that its recommendations to the industry have been widely accepted and put into general practice. Indeed the principal purpose of the Committee is to investigate any problem of projection that may be facing the industry, to determine the existing circumstances, and to recommend any alterations in these circumstances that may be dictated by the needs of good projection.
Perhaps one of the most important of the projects that has been undertaken by the Committee is the revision of the earlier projection room plans. The first set of projection room plans was drawn up by the Committee in 1930, and since that time the many advances in the art of projection and in the projection equipment have made it necessary to revise the plans, the latest edition being that published in the November, 1938, issue of the JOURNAL. Naturally, the establishment of a set of plans aiming toward a high level of projection, operation, maintenance, and safety would lead toward a thorough investigation of projection room design from the point of view of fire prevention and control. These plans and survey have been published in The Architecture Record, thus bringing them to the attention of architects of the country and so contributing toward improvement in theater design. In the same issue of the JOURNAL was published a
