| Fully compatible
with, and quickly convertible for 70mm or 65mm film with up to six magnetic
sound tracks, 35mm CinemaScope with four magnetic or single optical sound
tracks, and Perspecta-sound, Wide Screen film of any aspect ratio with
either magnetic or optical sound and standard 35mm film. Scientifically compounded curve of light gate - prevents film buckle. Single blade double speed conical shutter, providing highest light transmission of any projector. Leading and trailing edges have integral air scoops that aid in dissipating heat. Rollers, drums, sprockets and film gate made from non- magnetic materials - eliminates possibility of magnetic soundtrack damage and necessity for frequent degaussing. Dual sprockets on all shafts machined of hardened aluminium alloy. No sprocket change required when changing from 70mm to 35mm or visa versa. (Less than 4 minutes required.) Two independent motors on each projector, 24 and 30 fps- all past, present or contemplated 70mm films can be projected without additional expense or modification. Combined ten-track magnetic clusters, no tricky threading required when changing from six- to four track reproduction. Triple filtered metered lubrication system. Substantially constructed for rock steady projection. All modern, domestic high-power arc lamps adaptable without loss of efficiency. Lathe bed lens carriage, positive alignment of lens to film path. Factory installed internal wiring, reduces installation costs. Adjustable for all projection angles - from 28 degrees downward to the upward angles required in drive-ins. Complete stock of replacement parts always available. Fully Underwriters' Laboratories Approved. |
