A feature be sent to anyone addressing the manufac of Williams screens is a protective coating turer, located on Summit Lake Boulevard, which covers the entire screen surface until Akron. PROJECTION EQUIPMENT INTERNATIONAL PROJECTOR CORP. essayed a further step in its campaign to improve the quality of projection by developing a new 35mm. projector named the Simplex X-L. The newcomer to the Simplex family, the result of five years of designing and tooling up and of an exhaustive series of field tests, was represented as incorporating a number of radical changes in design and operation and was said to be capable of a maximum of efficiency, complete reliability, economy of operation and extended life. The operating side of the projector head was furnished with a large glass panel which, with the assistance of the iluminated film compartment, permits the operator to view the whole mechanism while it is in action. An enlarged sightbox exposes the vital aperture area to view. The Simplex X-L has a lens mount capable of taking care of any projection lens up to four inches in diameter and with a speed of f 1 .6. Focusing of the lens is simplified greatly by means of a micromatic “Screenscope.” There is a simplified lubrication system termed the “SprayO-Matic.” The projector lays claim to fewer parts, less gearing and quieter operation. Sprockets contain 24 teeth which operate at only 240 rpm. Other advantages cited are reduced mechanical load, frame lock indicator, extra-long tension shoes and film magazines a quarter inch deeper on either side of the reel. As the Film Daily Year Book went to press International Projector Corp. was working on new projects for 1950. TO MAKE POSSIBLE the air-blast cooling of projectors the DeVry Corp. of Chicago in 1949 came up with what it called the "Koolite” system. The firm made the claim that at last it had found the solution “with reference to the adequate cooling of both projector mechanism and film.” Attachable to all series 12,000 DeVry projectors, the cooling device increases the life of prints and is regarded as a godsend especially to drive-ins which find heightened screen illumination a big asset. The "Koolite” system comprises an air blast directed over the aperture rails and past the film face and an exhaust unit removing the heated air from the projector head itself. Last year DeVry also completed new projector designs employing special sapphire inserts at points of concentrated wear. Elimination of difficulties resulting from the uneven rates of wear on various parts of the projector mechanism was credited to the new development. The DeVry Corp. in 1950 celebrates its 38th year as originator, developer and manufacturer of precision motion picture equipment. The popularity of DeVry products in the domestic and foreign markets continues at an accelerated pace. For the 1950 theater market DeVry offers improved “12000” Series projectors and amplifiers, as well as in-car loudspeakers for drive-in installations. In the 16mm. field DeVry is manufacturing a new improved, lightweight, low-priced, single-case “DeVrylite” 16mm. sound-on-film projector that sells for only $345. Outstanding among equipment advances developed by DeVry include the new JAN (Joint Army-Navy) 16mm. sound motion picture equipment. Currently this equipment is being delivered to the U. S. Navy and Army. Chief characteristics of the new JAN equipment are its ruggedness, moderate weight, high illumination output, high-fidelity sound system and its adaptability to a wide range of applications from small classrooms to theaters and auditoriums having projection throws as far as 180 feet. DLTRING 1949 Century Projector Corp. of New York intensified its development program to keep pace with other industry advancements. The following improvements and new designs were intensively investigated and subsequently released: water-cooled pro jector apertures, 4" diameter lens mounts, secondary framing apertures, drive-in pedestals, drive-in magazines, locking doors on projector mechanisms and sound reproducers for drive-in theaters, 200-watt drive-in power amplifiers, new main amplifier switching panel, power amplifier switching panel, exciter lamp power supply switching panel, new higher-power rectifiers for exciter lamps, improved power amplifier monitoring, improved film sprocket designs. It is the firm’s belief that these improvements, although not particularly publicized, have resulted in advancing the art of motion picture presentation by taking advantage of modern materials and designs for higher efficiency, more accurate film registration and improved sound reproduction. The water-cooled projector mechanisms were given special emphasis by the company. They represented Century’s answer to the problem of film distortion caused by the use of extremely high arc lamp wattages.
