MONTHLY CHAT THANK you one and all for the nice reception accorded the last issue of I. P. Such close attention by and grand cooperation from the field cannot help but work out very well both for I. P. and its reader friends. Incidentally, can we help it if I. P.'s circulation has increased eleven per cent within the past two months, even as its advertising this month increased twenty-eight per cent? IF THE electrics survive the cargo of poison gas unloosed in their direction upon disclosure of their "extended" servicing plans, projectionists will have only themselves to blame. The signing of a couple of circuits who happen to be heavily in debt to the electrics doesn't insure the success of the plan. WHAT ever became of the grandiose plan to sell a million dollars worth of equipment to theatres through federal modernization loans? Probably those trade papers who "created" this fantastic tale will now explain why they ducked out of running follow-up stories. The story was pretty lousy anyhow, for it served only for one issue. NEXT month will be handed down the U. S. Supreme Court decision on the Tri-Ergon mess. Should Mr. Bill Fox win out, projection rooms will witness feverish activity by the electrics to alter their heretofore well-advertised "patentprotected" sound equipments. CONVERSION of existing low-intensity lamps for use with Suprex carbons has never appealed to us, except when the process was necessary to practically force the production of D. C. lamps in opposition to the A. C. junk then flooding the country. Now that D. C. Suprex operation is generally approved, and lamps therefor available, we can see no reason for continued use of converted lamps. More than a year ago we counselled lamp manufacturers not to oppose conversion jobs, because the conversion job of early 1934 almost certainly meant a new lamp sometime in 1935. The soundness of this advice is now being demonstrated throughout the country. Why is a conversion job unsatisfactory? The detailed answer will appear herein next month. Manufacturers' orders for reprints filled in order of receipt. DR. A. N. GOLDSMITH certainly slaughtered the television stock promotors during his recent Cleveland speech relative to new advances in the electronic art, a brief resume of which appears herein. Better still, a nationwide radio hook-up carried the good Doctor's message to a tremendous audience. Which is all to the good, in view of the current activity by television stock enthusiasts.
