cine equipment. Most of il centered on the pulsed discharge lamp.
This tiny lamp — the size and shape of a clinical thermometer — in its original form consumes 800 watts, yet produces as much light as a 2 k\\ arc. It flashes 3 times per picture frame, instead of twice like the ordinary shutter. A demonstration showed the practical value of this. Two pictures were projected side by side, lit to exactly the same measured brightness of 27 foot-lamberts; on the left was an FP7 projector with arc. on the right the FP20S with pulsed lamp. At this high brightness le\el the arc-lit picture showed a very noticeable flicker, which was completely absent from the picture lit by discharge lamp.
The screen illumination from the 800-watt lamp is 500 lumens — low b] I . S. standards, but adequate for most of our theatres. Now introduced is a more powerful lamp consuming 1000 watts: with an improved mirror system this gives a screen illumination of 9000 lumens. We saw a 70mm film projected on a 40 ft. screen, with excellent brightness. On this large screen, and in a small auditorium, the evenness of illumination from centre to edges was most noticeable. iP
Three New Processes To Be Demonstrated For Large Screen
Three new large-screen color processes are due for demonstration soon: National Generals Talaria. the Todd AO-Dimension ISO s\stem ami color Kidephor.
Theatre Network Television held a demonstration of color Kidephor. a theatre closed circuit, the result of years of development, at its technical center at Woodside. L. 1. The demonstration was sponsored with TNT l.\ CIBA Ltd.. involved in Eidephor. and Philips of the Netherlands, which provides optical systems.
While the Eidephor demonstration will be on a 12xl6-ft. screen, a TNT spokesman said the process is intended for large screen theatre TV.
Dimension 150 coupled with Todd AO had another demonstration for company executives in Santa Monica. Calif., and an exhibitor demonstration there is being scheduled.
The General Electric Talaria system, which will be used in the Theatre-Vision Color closed circuit theatre network, is planned for demonstration shortly on the West Coast and in New York. iP
