NEW EQUIPMENT NOTES ON RECENT DEVELOPMENTS IN PRODUCTION & PROJECTION • Thk Increasi.n'G demand for color in slidefilm and motion picture production this year brings up an important consideration of the showing: problems involved. With the perfection of 16 mm. printing by Technicolor and Kodachrome processes and developments by Cine-color and others in this field, the sponsor must now be assured the maximum illumination in order to assure audiences proper screen quality vital to the enjoyment of these films. Not only announcements of increased brilliance from existing 750-\vatt lamps but consideration of the 12nO-watt sizes and also of 16 mm. arc projection are of interest in this regard. Particularly before audiences in large rooms under poor lighting conditions the arc projector insures necessary screen brilliance. Choice of proper screens is another factor deserving thought. Typical Arc Equipment ♦ For utmost illumination of 16 mm. films on large screens, etc., the Ampro Model '"AA" 16 mm. Arc Projector is typical of this type. 30 Amp. high intensity arc, automatic carbon feed tri-purpose amplifier, and two speakers are standard equipment. Also in this classification is the Bell & Howell Filmoarc which now produces approximately 1200 lumens as a result of recently increased light output. This equipment comes complete with The Am/'io Model "AA" 16/»;h Arc Projector jor larger audiences amplifier, rectifier, two magnet dynamic speakers and all connecting cables. The DeVry 16 mm. Arc Projector is another theatrical quality unit in this classification, also sold complete with speaker, amplifier and other accessories. All of these units are priced at approximately $1,000 to $1,200 with accessories, 1200-watt lamp projectors range several hundred dollars lower ill price. Victor's luic tly'"-U!-'>iU' s/^rilK'i-r described in the item behni' ♦ Of interest in the educational and industrial fields are new improvements made by the Victor Animatograph's engineering department. One is Victor's new twospeaker unit in one case under one handle. This eliminates the necessity of carrying two cases in addition to the projector when two speakers are required. Another development is an increase in the output of the Animatophone amplifiers, of 100% in the Model 40A and 50^f in the Model 40B. Both have separate "mike'" control built in. Still another is the adding of even greater film safety to Victor's film protection developments. .-l/ii/jro'.s New York Office ♦ New and spacious quarters at 515 Fifth Avenue in New York City were announced last month by the Ampro ('orporation. THO-U all Lamp Doubles Lifihl ♦ Owners of 16 mm. Filnisound |irojectors will be interested in the new 750-watt, lO-hour lamp recently announced by Bell & Howell. It is claimed that by actual test this new unit produces 50% more light than the standard 750.watt, 25-hour lam|). The (Company states that for many months their engineers have lieen working with the lamp manufacturer to produce a more brilliant lamp in the standard size, seeking to accomplish this without increasing the wattage over 750. and thus without increasing the heat to the point of possible danger. The result of this research is the new. 750-watt, 10-hour lamp, which, although far greater in brilliance than the standard 750-watt unit, generates little or no additional heat. Although the minimum life expectancv of the new lamp is but ten hours, it is felt that this reduction is far outweighed in importance by the added brilliancy. B & H states that for projector illumination, the new lamp is excelled in light output only by the 1200-watl. 10-hour lamp in the larger glass envelope, which is used in the Filmo ""Auditorium" Projector. Bell & Howell makes it clear, also, that the new lamp does not replace the standard 750-watt, 25-hour lamp, which, it is believed, will continue to be used in the majority of home-owned projectors.
