International projectionist (Jan-Dec 1950)

Kodak's New Model 25' Heavy-Duty 16-mm Projector ANEW heavy-duty 16-mm projector, designed from the base up for auditorium and large group purposes, has just been announced by Eastman Kodak Co. Although reasonably portable, the projector, Model 25, is intended for permanent installation. If it is necessary to move it, however, the projector can be easily disassembled into three parts, each of which is provided with handholds. To attain a new level of durability and quietness, the mechanism of this new projector is divided into two mechanically independent but interlocked assemblies: the intermittent assembly and the shutter-sprocket system. These are driven by separate synchronous motors. Perfect start for Spring— —under RCA's In-Car Speaker Repair Plan Think of it — every In-Car Speaker and Junction box in your Drive-In operating at top efficiency when your season starts. No anxiety over your equipment at curtain time. No unexpected expense to face on last-minute maintenance. Under the RCA Sound Parts Plan, RCA Service Engineers give every RCA In-Car unit in your theatre a thorough Spring check-up — well in advance of the scheduled opening. Any speaker or junction box not up to RCA standards is restored to its original performance. Faulty speaker mechanisms and components are replaced with brand-new RCA parts. Spare speakers are maintained at no extra charge. Regular checkups continue throughout your season. For as little as a penny a week per car station, this plan is available to every RCA equipped Drive-In theatre on RCA Contract Service. Rates are arranged on either a weekly or monthly "seasonal" plan — whichever meets your needs. For complete information, wire or write — WHAT IT DOES FOR YOU • Assures you that all your In-Car equipment will be in top condition for the new Spring season — and be kept that way. • Provides periodical check-ups throughout your season. • Assures prompt and reliable service. • Relieves you of the work and worry of keeping your In-Car units working all the time. • Enables you to budget upkeep costs. RCA SERVICE COMPANY. IMC. A RADIO CORPORATION of AMERICA SUBSIDIARY CAMDEN, NEW JERSEY Individual motors also drive the blower, takeup, and rewind. The entire projector is designed on a mechanical unit basis for greater efficiency and ease in serviceability. Thus, the lamphouse is one unit structure; the intermittent system another, etc. Any of the ten major components of the projector may, as a result, be easily removed for service. Following standard 35-mm practice, an intermittent sprocket is used instead of a claw-type, pull-down mechanism. Positive and accurate film transport is provided by an 8-frame sprocket driven by an accelerated Geneva star. The twointerruption-per-frame shutter has a light transmission of 65%. Equipped with a 1000-watt, 10-hour tungsten lamp, the Model 25 delivers considerably more screen illumination than has been possible previously with 16-mm equipment. It has also been designed for use with arc illumination under more stringent projection condi New Eastman Kodak Model 25 heavy-duty 16-mm sound and visual projector. tions. Sufficient illumination is provided by the arc lamphouse to achieve optimal screen brightness and to fill a screen having dimensions which are twice those allowable when the tungsten lamphouse is used. Greatly Improved Optics The projector is being offered with a new type of lumenized Kodak projection lens specially designed to give excellent flatness of field and image resolution. This lens is offered in a choice of focal lengths: 2, 2%, 2%, and 3 inches. All lenses have an F:1.5 aperture. In the tungsten model, a dual lamphouse incorporated in the projector prevents show interruption if a lamp burns 24 INTERNATIONAL PROJECTIONIST • MARCH 1950
