Since the "standard" was established, however, numerous developments have occurred in direct 16-mm production which now practically compel the recognition of so-called "non-standard" prints as a factor of fast-growing importance in our rapidly growing 16-mm industry. The expression "non-standard" emulsion position no longer carries the stigma ordinarily associated with other things that are called non-standard. Optical Printing of 16-mm. Unlikely Motion picture films may be printed either by contact (the emulsion of the film to be copied is in physical contact with the raw film upon which the copy is to be made) or by optical printing (the emulsion of the two films are not in physical contact; some form of lens system is interposed between the film to be copied and the raw film upon which the copy is to be made). By far, the largest percentage of picture film printed today is printed by contact methods. It does not seem likely that 16-mm-picture film will be printed optically in the near future for a number of reasons, not the least of which is the lack of available lenses due to the defense program. The use of Kodachrome duplicates has been growing very rapidly and since contact printing of Kodachrome originals will continue to be used for some time, the "nonstandard" emulsion position will continue to be a rapidly growing factor in 16-mm-soundprojection that can not be ignored. STREAMLINING A SOUND PLANT Loren L. Ryder Paramount Pictures, Inc. This paper discusses the trend in modern sound-recording equipments. It reviews the objectives and requirements that are now existing in regard to studio recording as contrasted .to previous recording systems. Several new developments in the art of sound recording are discussed and from this group are selected a complementary series of improvements which together are stream* lined into a new recording plant. SOME EQUIPMENT PROBLEMS OF THE DIRECT 16-MM PRODUCER L. Thompson The Calvin Company The production of industrial films by the direct 16-mm method is now definitely out of the experimental stage. As more industrial work is done by this method there is an increasing demand for more and better 16-mm equipment suitable for professional use. Such equipment can be developed successfully only after the-professional user has found by actual experience what he needs and wants. MOBILE TELEVISION EQUIPMENT R. L. Campbell, R. E. Kessler, R. E. Rutherford and K. V. Landsberg * Allen B. DuMont Laboratories While portability is a necessary requirement for outside pick-up equipment, several advantages result when portability is carried into the studio. To equip a studio of adequate size with fixed equipment for operation of several cameras involves considerable time and expenditure. However, with portable studio equipment, the entire equipment installation can be located to suit studio needs, as well as moved to different studios or outside locations. The dolly type of equipment is described in some detail, and systems for program control are discussed. Some of the design features discussed are portability and flexible synchronizing equipment; electronic viewfinders; oscilloscope monitors: and other operating facilities. PRODUCTION AND RELEASE APPLICATIONS OF FINE-GRAIN FILMS FOR VARIABLE-DENSITY SOUND RECOVERY C. R. Daily Paramount Pictures, Inc. Fine-grain film materials have supplanted the normal positive type emulsions for all variable-density sound recording and printing operations. The sound-quality improvement realized by the reduction in noise and dis CLAYTON BALL-BEARING EVEN TENSION TAKE-UPS For all projectors and sound equipments AH take-ups wind film on 2, 4 and 5 inch hub reels.
