International projectionist (Jan-Dec 1947)

far as American practice goes (wrongly, in the writer's opinion), does provide a highly useful and significant im provement in signal -to -noise ratio.

To salve the conscience, it would be a good idea to keep a log of the settings found most pleasing with different types of programs, and after about a year try and analyze the results with a view to ascertaining the preferred frequency characteristic. In presenting this information on such a widely-debated subject, the writer has attempted to avoid inserting any personal bias either for or against the subject matter. The, results present a disconcerting discontinuity in our previous line of thought, and it would appear imperative to obtain some further evidence of the mass reaction to frequency range restriction. The individual opinion of an engineer would appear to be less important than that of an ordinary member of the public lacking all knowledge of the prior art. 'Weekend' Tops Film Daily Poll "The Lost Weekend," a Paramount release starring Ray Milland, was rated the No. 1 motion picture of 1946 by 447 out of a total of 559 American reviewers for press and radio who participated in the 25th Annual Film Daily "Ten Best Pictures" poll. The remaining nine top films placed in the following order: "The Green Years" (M-G-M) ; "Anna and the King of Siam" (20thFox) ; "The Bells of St. Mary's" (RKORadio) ; "Spellbound" (UA-Selznick) ; "Saratoga Trunk" (Warners) ; "Henry V" (made in England and released by UA in Amerca) ; "Notorious" (RKORadio) ; "Leave Her to Heaven" (20thFox) ; and "Night and Day" (Warners) . Oddly enough and despite the steadily increasing use of color, only three of the winning pictures were color films, all done in Technicolor. RCA 16-MM STUDIO ON WHEELS The first complete mobile recording unit to be developed especially for 16-tnm sound film recording has been designed and custom built by the RCA Film Recording Department. The unit consists of a complete film and disc recording channel installed in a custom-built body which is mounted on a 1^-ton truck chassis. The recording channel is of the Hollywood studio type and has all the features normally found necessary for the operations of major studios. The optical system and film path of the standard RCA Model PR-23 Film Recorder installed in the mobile unit was specially modified to permit recording of direct positive as well as negative variable area sound track. The film recorder also includes a photographic slater and a synchronization marking system. For "location" recording, the channel can be operated entirely by batteries which have sufficient capacity for approximately 20 hours of normal operation. Special windings on the motors of the camera and recorder permit interlock operation from either a 96-volt battery source or a 220-volt, three-phase supply. 28 INTERNATIONAL PROJECTIONIST • February 1947
