The Educational screen (c1922-c1956])

EQUIPMENT Radiant Educator B&H Striping in Hollywood Synchrotone The new Radiant "Educator" is announced as the strongest, most versatile projection screen in its price Z class ever developed by the Radiant Screen Company. It incorporates several unique features, the most unusual of which is its adjustability from a low of 9'^" above the floor to a height of 110" in the 70" model. It is made in three large square sizes, 50" X 50", 60" X 60", and 70" x 70". The square sizes for slides convert to rectangular sizes for motion pictures.

Synch roslide A new method of accurately and automatically synchronizing recorded commentary with projection slides has been developed by Synchromatic Products Company, Bayonne, New Jersey. With the system, known as Synchroslide, the taped commentary may be "cued" for slide changing, using white "cueing patches" applied to the back of the magnetic tape. When the "cued" portion of the tape passes through a specially designed electric eye mechanism, the slide projector's changing apparatus is triggered electronically, resulting in an automatic change of slides. The white "cueing patches", ordinary white cellophane tape, may be removed and switched about as desired without harming either the tape or the sound quality. Thus the user may experiment until he gets the splitsecond accuracy he desires. 8mm Recorder-Projector Movie-Mite Corporation (1116 Truman Road, Kansas City 6, Missouri) has announced the Movie Sound Eight, the first 8mm sound-on-film projector on the market. The complete recorderprojector, weighing 35 pounds, is announced as incorporating all the latest developments in magnetic recording. Two separate recording channels are provided so that narration and background music may be recorded simultaneously. 8mm Magna-Stripe Magna-Stripe, the new magnetic sound developed by Soundcraft for 16 and 35mm motion picture film, is now available for 8mm film, it has been announced by Reeves Soundcraft Corporation (10 E. 52nd St., New York City). This announcement coincides with the announcement by the MovieMite Corporation, Kansas City, Missouri, that their new 8mm magnetic projector is available for the consumer market. The addition of Magna-Stripe to 8mm film will enable 8mm movie fans to turn their silent films into sound films at the cost of 3V4 cents a foot. The expansion of Bell & Howell's magnetic film striping service to its Hollywood plant was announced recently. The company's Soundstripe process prepares 16mm film for magnetic sound recording. Film may now be mailed either to Bell & Howell at 716 North LaBrea, Hollywood, or 7100 McCormick Road, Chicago. Bell & Howell has also announced that silent film exposed in all types of 16mm motion picture cameras (both magazine and roll film) can now be striped for magnetic sound. The new development permits the magnetic recording and playback of sound directly on standard silent film, perforated along both edges. A new type of tape recorder called the Synchrotone has been announced by the Mag:netic Recording Industries (30 Broad St., New York 4, N. Y.). It permits the synchronous recording of two different sound events on the same tape, without actually mixing the sounds on the tape. The two recoi'dings may be made simultaneously or at different times. Each may be erased, corrected, changed in relative volume, or copied — without affecting the other. Yet both may be played back together in perfect synchronism at any time. The machine is said to be especially valuable for drill and practice where the student must make a response to an aural situation, as in pronunciation MC300 PROJECTOR ^ WE challenge'' * ic COMPARISON with projectors at all price levels 4 FOR BRILLIANCE, -^ j^ FOR CLARITY, FOR CONVENIENCE "^ • • * -^ • The 2" X 2" slide and filmstrip projector with triple action fan cooling that keeps lamphouse comfortably cool . . . twice the brilliance you'd expect from 300 watts . . . instant switch from slides to filmstrip and back . . . 360° rotatable front stops anywhere, assures upright frames . . . choice of 3 AMERICOTE objectives—all achromatically and anastigmatically balanced for clarity, color, and brilliance . . . instantaneous film' threading ... no glass pressure plates — nothing to mar filmstrip surface.
