International Projectionist is not responsible for personal opinions appearing in signed articles in its columns. MONTHLY CHAT |)ECIDEDLY a hit is the series ot articles on mathematics for the projectionist, authored by Gordon S. Mitchell, now current in these pages. For years now we have speculated on ways and means to goad our readers into letter-writing, but no question-and-answer series of articles rang the bell until the Mitchell articles hove on the scene. There must be other topics which would prove equally interesting to a majority of readers, and we certainly would like to receive a few suggestions along this fine. I~)UR wearied postman is further burdened by hundreds of letters of thanks from organizations and individuals relative to our distribution of code information immediately following the close of the Washington hearings. Proud to serve such an appreciative audience, I. P. is content to say "You're welcome". "R CAVICTOR CO. is reported as about ready to form a $30,000,000 subsidiary to promote its television interests. Said information wins little credence from us, but it does serve as a reminder to have another look into the present state of the television art. The new N.B.C. studios in Radio City are thrice prepared down to the last circuit for television broadcasting — when, as and if a number of technical problems and one big merchandising problem are settled. The answer to the question, "Who's going to pay the tariff?" will determine the possibilities for television within the near future. "Y^"E don't relish some of the practices now current in the theatre equipment field, particularly with respect to compulsory servicing, the blanket repair and replacement part contract, so-called, which is sponsored by Erpi, and the release of false information regarding operating values of certain types of sound tubes in order to harass the independent tube manufacturer. It occurs to us to ask why, if RCA can sell its sound reproducing equipment outright and not impose compulsory servicing burdens on exhibitors, Erpi should not do likewise. Maybe the impending suit of 102 New York exhibitors against Erpi will provide the answer to some of these questions. PROJECTIONISTS' modus operandi makes them easy marks for colds which often develop into something more serious. Read the Cold Code within, and watch yourself. Every year at this time we make an appeal for support of the Xmas Seal drive. A pleasant duty on our part, for we have personal knowledge of the aid rendered to projectionists by the organization backing the Seal drive. Buy Xmas Seals.
