THE FUTURA positive can be burned at from 7 to 20 inches per hour as desired. The use of a single Bi-Powr silicon stack transformer-rectifier is recommended as an ideal power suppl) for two Futura lamps. I iterature on the new futura will be sent to anyone addressing a request to the Strong Electric Corp.. 31 Cit\ Park Vvenue, Toledo I, Ohio. iP Cinerama Develops Non-Louvered Screen Cinerama has disclosed it is developing a new screen to eliminate the present louver system. The new development is planned for introduction in theatres after the current conversion to the new single lens process is completed. The new screen will cover the same large viewing angle as the wide, multi-louvered screen now in use, but invisible miniature ribs will replace the louvers as part of a smooth surface. The present Cinerama screen characteristics will be maintained, but with increased efficiency, the developers claim. iP New 16mm Projector Uses Xenon Arc A new light source for 16mm motion picture projection, a Xenon arc. has been announced by the Strong Electric Corp. Known as the Strong X-16. the lamo is adaptable to such projectors as Eastman arc and incandescent. Norelco. Hortson. Bell and Howell. Victor. RCA. and Ampro. The li<rht source utilizes tungsten electrodes to provide an arc in a Xenon gas atmosphere, totallv enclosed in a quartz envelope. It has the advantages of providing a steadv. flickerless. pure white light source with no discoloration and with extremelv even distri bution of light over the total screen area. The spectral composition of the Light, which is unaffected b\ voltage variations of the power line supply, results in excellent reproduction of color films. The equipment, once aligned and focused, needs no further adjust ment. No moving parts are employed in the light source and no special cooling is required. Four models are available: 150. 900, 1600 and 2500 watt. The igniter is built into the lamphouse and provides the proper starting or ignition voltage. The associated silicon diode transformerrectifier is specially designed to provide the exact current characteristic and regulation capa bility for optimum operation of the light source. Literature on the X-16 can be obtained by addressing a request to the Strong Electric Corp, 31 City Park Avenue. Toledo 1, Ohio. iP Wilschke Joins EPRAD; Pioneer Sound Engineer Elmer O.
