International projectionist (Jan 1963-June 1965)

■■ New Sound System Makes In -Flight Motion Pictures More Enjoyable \ revolutionary new sound system for Inflight Motion Pictures aboard jet aircraft is now in operation on both Trans World Airlines and [ nited Air Lines, it is announced b\ David Flexer, president of Inflight. The wbolh new sound concept was installed in all UAL jets. flying from California to Honolulu, and in I nited's long-range domestic aircraft. which started showing wide-screen, full color ino\ ie< on Sunday, January 17. The entire transcontinental and trans-Atlantic fleet of T\\ \ has also been changed over to tbe new system. I \\ \ has been featuring Inflight movies since 1961. "Tbe new sound development can provide true stereophony," Mr. Flexer said. ""It is based >>n a fundamental shift-over from a magnetic to a dynamic principle of sound reproducing." Ml future Inflight installations will feature the new sound system. I be Cinemeccanica CX-(X)0 NEW LAMPHOUSE — The Xetron Division of Carbons, Inc., Boonton, NT. J., announces the Cinemeccanica CX-900 lamphouse to its line of Xenon light saurces. This is a compact, highly effi ient unit, designed to operate with 16mm and 35mm projection systems. When operating at 45 to 50 amperes, this lamphouse will deliver 4000-5000 lumens of high intensity light. It is a complete unit including the high voltage starter, ventilating fan, seven inch reflector and elapsed time meter. It is said to be especially suitable for small screening rooms using 35mm projection and with 16mm applications to replace the carbon arc lamp. which carries not only the dialogue, music and sound effects track of the movie, but also a wide range of stereo and monaural audio programming. The new Inflight sound s\stem is the result of months of experimentation. Development costs exceed 8500,000. Originally the earsets, through which the sound is delivered to each airborne passenger, were equipped with a tiny sound head, which were about the size of a five-cent piece. Ihc\ were magnetic transducers. which bung from the left earpiece. I hc\ weighed about an ounce. The new earsets do awa\ with the magnetic transducers. Instead two dynamic sound heads, each four times larger than the original piece of equipment, has been permanently fixed in junction boxes attached to the airplane seal. The earset is now even lighter in weight. It consists of two acoustical plastic tubes, forming true stereophonic sound conduits. 1 he earpieces have been redesigned to fit the contour of the head and inner car. Disposable plastic eat ti|>^ lit snugly against the car drum, shielding out cabin noises and making a rich and firm sound contact. ["he dramatic improvement in the Inflight sound system was made possible b\ the development of solid state transistorized amplifiers, small enough for aircraft application which for the first time, could deliver sufficient output to handle the doubled number of four-times enlarged dynamic transducers. The junction boxes also have been fitted with new sensitive volume controls, so that the passenger can find the level best suited to his own enjoyment without disturbing any other passenger. iP THE VERY FINEST PROJECTOR PARTS SINCE 1908 The ultimate in precision, long life and dependability— they keep projectors in top operating condition essential to good pictures, patron satisfaction and good business.
