Motion Picture Herald (Jul-Aug 1943)

August 2 1, 1943 BETTER THEATRES 67 light at f:2.5 as at f:2.2. This results in an average screen illumination of 11.7 footcandles at f:2.5, rather than the 15 footcandles transmitted at f :2.2. At f:3.0 only 54% of the light transmitted at f :2.2 is available, and the screen illumination is only 8.1 foot-candles, instead of 15 foot-candles. At f :3.1 only half as much light is transmitted as at f :2.2, and the screen is only half as bright. Is Wartime Salvaging Of Copper Worthwhile ? Edgar Cramer, projectionist of the Sherman theatre, Stroudsburg, Pa., asks the following interesting question regarding the success of the drive to salvage copper from carbons : "For some time projectionists have been turning in all carbon stubs, peelings and drippings to their supply dealers in an effort to salvage as much copper as possible from all types of copper-coated carbons. I'm rather interested in how really successful this salvage work is progressing. Could you tell me what percentage of the copper is being returned, and of this how much pure copper is actually reclaimed?" Maybe many projectionists have been wondering about this. Allen G. Smith, chief of the Amusements Branch of the War Production Bcfard, recently reported that the salvage of carbon copper drippings is now routine procedure in practically all theatres and that from 110,000 pounds of copper plated on carbons, 99,000 pounds have been reclaimed. This indicates that 90% of the copper is being returned. Copper drippings yield 90% pure copper. It demonstrates how important this salvage work is and how well projectionists and supply dealers are doing their part in the vital job of getting every possible ounce of this strategic war metal in. While on the subject of salvage, it might be well to advise those who do not already know it, that supply dealers no longer want stubs turned in. Continue to turn in all peelings and drippings as you have done in the past, as they constitute the important reclaimable metal. As it is difficult, if not impossible, to peel the thin copper plate from Victory stubs, the drippings represent the bulk of this reclaimable metal. When Light Can Be Called Well Distributed Les Condit, projectionist of the Park theatre, in Caldwell, N. J., has several questions concerning the distribution of light on the screen. He submits them as follows : "Question 1 — In referring to the light on a screen, is it correct to use the number of foot-candles at the center of the screen, or must the average of the center and several other points be used to designate cor Know Your Motiograph Dealer He's the Man of the Moment!
