International projectionist (Jan 1959-Dec 1960)

film of silicones applied by the cloth is not "tough" but very similar to a film of ordinary grease or heavy oil. Silicones spread to a greater extent than ordinary greases, however, and feel "dry," rather than oily, because of their powerful moisture-repellent properties. Probable Useful Application A silicone film is removed more readily by film-cleaning liquids than is an oil film. Actually, the ease with which silicones are dissolved by hydrocarbon oils and greases renders them very impermanent as movie-film coatings. Ordinarily, release prints come in contact with oil used for lubricating projectors. The presence of oil removes silicones with amazing rapidity. It seems that the most useful application of the cloth lies in the direction of lubricating the sprocket-hole edges of green prints, waxed or unwaxed. A silicone coating on the film margins of new prints (emulsion-side only) would materially reduce the likelihood of "sticking" in the projection gate, and is superior to the use of ordinary oil because it would not "spot" the picture and soundtrack areas to an appreciable extent. Unfortunately, however, such cloths do not readily lend themselves to the IMPORTANT NOTICE . ... On your Strong Arc Slide Projector you can now mount the GENARCO ELECTRIC SLIDE CHANGER which holds 70 slides, V/4" x 4", and change them in V2 second by pushbutton remote control.

Some kind of simple applicator device would be a minimum requirement for this job. Lubrication of gate runners and tension-pad surfaces with silicone may possibly be helpful when running green prints, especially unwaxed ones; but the silicones would undoubtedly vanish after the passage of 50 to 75 feet of film, and be removed almost instantly by a few feet of oily film. Victoria X Projector in U. S. Distribution Bow Another entry in the wide-film projector market in the United States is the Italian Victoria X "all-purpose" projector and sound system suitable for showing either 35 or 70-mm prints. The system will be distributed exclusively by Cinematograph International, Inc., 341 West 44th St., New York City, which is headed by George Hornstein, veteran equipment dealer. The Victoria X will be included in a "package" deal which will comprise the entire reproduction system from projection room to screen, including full engineering advice and servicing. Cinematograph, Inc., also distributes Ampex magnetic and optical sound systems. Complete Flexibility Assured The Victoria X approximates the Philips dual-purpose projector, with its sprockets having four rows of teeth, a three-lens turret and a curved gate. Completely flexible, the Victoria X may be used in combination with other makes of American sound systems and arclamps. It may be used for all film processes, including Todd-AO 65-70 mm. six-channel magnetic film, and for all aspect ratios of 35-mm film with threeor four-track magnetic sound for CinemaScope, single-track mixed magnetic sound, and single-track optical sound. The change from 70-mm to 35-mm film requires less than a minute. The Victoria X is used extensively in the finest European theatres. Technikote Screen Scores Two world premieres of important 1959 "blockbuster" film releases — "Mardi Gras" and "The Buccaneer", the latter Cecil B. De Mille's last production before his untimely death — were aided by the selection of the XR-171 screen produced by the Technikote Corp. of Brooklyn, N. Y., Leonard Satz. The XR-171, an improved version of the XR-170 (exported world-wide by Westrex) has the advantage of high brightness-gain without apparent fall-off at the sides. Complete uniformity of surface from edge to edge is made possible by a new technique of application of the pure plastic material. The screen surface is smooth, seamless and stays remarkably free of dust. Overall Uniformity Achieved The absence of any surface roughness in the form of embossing, whether "designed" or otherwise, has its advantages in the opinion of Satz, whose experience dates back to the first sound film. Reflectance characteristics can be maintained at an extremely high level with the all-smooth surface, and most important of all, perfect uniformity results. Technikote also furnished XR-171 screens for the newly-refurbished Kentucky theatre, Lexington, Ky., and the Roosevelt, Miami Beach. G.E.
