International Projectionist is not responsible for personal opinions appearing in signed articles in its columns. MONTHLY CHAT COMING events cast their shadows before. The joust between Chicago Local 110 and the I. B. E. W. outfit as to who has jurisdictional rights over the television equipment now being used at the World's Fair is just a sample of what may be expected in the future. Thus far. the electricians are in front in the controversy. There seems to be no question that television, when ready, will utilize the projection process, the action to be photographed on film. Of course, from the I. B. E. W. point of view the possession of even an electric ice box without benefit of one of their maintenance men is nothing less than a felony. IT'S nothing in the projection line, but the news that Paramount will continue ivrough the 1934-35 season its policy of not selling 10-cent theatres is good news for show business generally — projection included. MR. EARL CARROLL'S much publicised plan to use projected backgrounds for his flesh stage shows is old stuff. The industry trade press went for this Carroll stunt in the biggest sort of way; but any first-class presentation house, having a live projection man, has known and used this stunt for years. For Mr. Carroll's information, it won't work out. THREATS of suspension of film service have recently been utilized to force exhibitors into line with Code Authority decisions. This same tenacity applied to labor provision compliance, following regional board decisions, would make for happier relations all around and prevent such conditions as exist in New York, in Kansas City and elsewhere. WITHIN another month no less than three new 50-ampere D. C. projection lamps will make their bow. Using 'he new Suprex carbons, these new lamps will eliminate any possible excuse for poor screen illumination. Even on the ground of economy there can be no argument, for the savings in current and carbons effected by these lamps will amortize a goodly portion of their cost within a year. Those now using low-intensity or hi-low lamps might well pay particular attention to this new equipment. IN A cooperative ad. in Variety projectionists at the State-Lake Theatre, Chicago, are listed under the heading, "Kino Booth". We relish this choice addition to projection nomenclature, and hope that five -years is not too long to wait for these State-Lake orchids to discover the term, 'projection room".
