International projectionist (Jan 1943-Dec 1944)

mounting screws, tighten them up. Focus lamp and then remove the board. The crayon will have marked on the board the spot for the center hole. Drill out this new hole and replace the terminal board in position. The board is now as good as new. — G. Reiger. RCA. Money Collector Recently I was in a theatre at a time when a collection for the infantile paralysis fund was taken up, and when counting the "take" difficulty was experienced in separating the dimes from the new pennies. As these new pennies are partly steel, I tried picking them out of the collection with a magnet. This worked fairly well but was too slow until I made a magnet that would work on 110 volts. With this new magnet the pennies were separated from the rest of the collection in two sweeps. — J. M. Esbenshade. RCA. Checking Fuse Holders I have found it to be a good policy to check all fuse holders that have very loose fuse clip mounting in order to eliminate the danger of their becoming loose. I sweat them to the face of the holder and make certain that the fuse is free enough to turn in the clip when it is replaced. This check-up will prevent lengthy sound outages that occur with blown fuses. — W. H. Reasin. RCA. The Spark That Lights The Flame of Victory A pinpoint of fighting metal placed in the arc of the spectrograph writes its own signature on a photographic plate. It reveals to the spectrographer each constituent, what impurities are present and in what quantities. Spectrography helps in controlling inspection . . . keeps tough fighting steels tough, helps in development of new fighting metals. Spectrography is used too in other fields . . . chemicals, foodstuffs, vitamins. It speeds research, control, and analysis. Because Bausch & Lomb had long ex perience with such precision optical equipment it was ready when the need arose for quantity production of the precision optical instruments of war. But through war and peace, Bausch & Lomb has continued . . . and will continue ... to do the job it knows how to do best. For Bausch & Lomb Instruments essential to Victor} — priorities govern delivery schedules. BAUSCH & LOMB OPTICAL CO. • ROCHESTER, N. Y. ESTABLISHED 1853 /. A. Elections L. U. 150, LOS ANGELES, CALIF.

ARMED FORCES' TALKIES AIDED BY NEW TECHNIQUE RCA engineers have found that direct recording of the sound track from 35-mm entertainment films to a special 16-mm negative is the most efficient method of transferring sound for 16-mm prints for the armed formes. W. V. Wolfe, manager of recording equipment sales at RCA's Hollywood plant, made this statement in presenting a paper on the subject before a meeting of the Pacific Coast Section of SMPE in Hollywood recently. As the 16-mm pictures are reproduced with portable or semi-portable equipment under conditions which vary from small halls to outdoor settings it is necessary, in order to meet these conditions to provide a reduced volume range and a modified frequency characteristic. It is no longei feasible to strive for dramatic expression, he said, "since we must be content with providing the maximum intelligibility possible under adverse conditions." DE FOREST LOOKS FOR EARLY POST-WAR TELEVISION Dr. William C. DeForest, who thirty-eight years ago invented the audion tube, from which have developed radio, radar and other electronic devices, on a recent trip stopped in Chicago to exchange greetings with William C. DeVry. president of the DeVry Corporation; E. B. DeVry, president of De Forest's Training, Inc., and W. N. Littlewood, chief of DeForest's educational staff. DeForest's Training was founded in collaboration with the late Dr. Herman A. DeVry to teach radio by means of motion pictures. Advanced electronics devices used in teaching radio, communications and electronics by the school which bears his name were given lengthy consideration, as was the subject of television, which Dr. DeForest says is an earlier post-war possibility for the nation's motion picture theatres than is generally realized. Projectionists, he feels, need to acquaint themselves with television techniques — and theatre operators keep closely informed on television developments. One of Dr. De Forest's patents was for a motion picture projector sound head vital to modern movies — an invention which brought him, the "father of radio and television", and Dr. DeVry, the "father of visual education", together in the early days of both radio and motion pictures. 28 I IV T E R IV A T I O N A L PROJECTIONIST
