International Projectionist is not responsible for personal opinions appearing in signed articles in its columns. MONTHLY CHAT WE direct the attention of the projection field to the story appearing in this issue relative to the projected all-inclusive theatre servicing plan which sound companies are expected to introduce shortly. Nobody is privileged to tell the sound people what they may or may not do; but projectionists, supply dealers and manufacturers owe it to themselves to carefully evaluate the effect of any such plan on their future welfare. We have always considered the sound serviceman as a potential threat to the security of projectionists, this theme being the topic of numerous editorials herein. Maybe constructive action looking toward the protection of Labor's interest in this field has been too long neglected; maybe it is not yet too late to do this job. Anyhow, careful consideration of the aforementioned story should start the thought mechanism to churning. NO other story that has appeared herein provoked the enthusiastic response induced by "The Suprex Carbon Arc" which appeared last month. The number and tenor of the hundreds of comments thereon which reached this office are indicative of the continuing interest of projectionists in things technical as well as a tribute to the intelligence of the craft. The A. C. arc failed to win general acceptance in this field not because of any mere collection of words appearing herein but because of the ability of projectionists generally to recognize an inferior product, despite a terrific ballyhoo accorded it. We congratulate the craft. SOUND reproducing systems of the near future will be of platinum with gold trimmings — if one is to believe the writers attached to the non-technical press who attempt to explain the "innovations" designed to walk around the Tri-Ergon patents. Summed up, it appears that the flywheel will have to be replaced. FOR the year 1935 we have to look forward to only the following: vastly improved color pictures, more hooey concerning the NRA; higher amperages for Suprex arcs; new rectifiers; 4,673 additional forecasts of "television just around the corner"; requiem services for the A. C. arc; bigger and better free radio shows; double reels; a couple new editions of projection tomes; lower wages and increased taxes; Congress; a hot summer; more "flesh" acts; more efficient projection optics — and better projection, we hope. OUR New Year greetings to one and all, without benefit of holly, or Old English type or two-color printing: the best of everything that life has to offer during 1935. (And may God bless the NRA.)
