safety factors and quieter sound reproduction, a new W5-19 power amplifier having 200 watts of undistorted audio power for drive-ins primarily, improved water-cooled apertures for reduced film distortion, and a new CI-T-220 recirculating water unit for use with water-cooled projector apertures and arc lamps to eliminate the need of tap water and waste disposal and to provide for anti-freeze treatment of water if required. New designs were incorporated into the lamphouse carriages of the Model C pedestals to provide more accurate centering of arc lamps and projectors as well as pedestal adapters for drive-in theaters. New lens mounts for Model C and Mode! CC projector mechanisms for the new four-inch diameter high-speed lenses with adapters for Series II lenses were adopted as standard equipment. The use of Century projectors exclusively on the Cinerama process of multiple-screen projection for "third dimension" effect increased the development activity of special projector mechanisms and sound reproducers. The coding of S2 complete new sound systems with power ratings from 1 5 to 400 watts, single and dual channel for indoor and outdoor theaters, was another Century achievement. DeLuxe Projector Mechanism Is Perfected by Wenzel ^^^NZEL PROJECTOR CO., perfected its deLuxe model projector mechanism, the PRO-50, and also its new WSH-3 sound head. The improved PRO-62 enclosed automatic rewind was also completed. A new Wenzel "Bull Dog" has also been perfected and placed on the market. This does away with the use of reel keys, will accommodate either wire weld or aluminum reels of 2000-foot capacity by use of studs or will, with its self-contained key, also handle 1000-foot exchange reels. For 1951 Wenzel has some new items in process of development and some others on the designing board. EK Presents New 16mm Heavy-Duty Projector ^ NEW HEAVY-DUTY 1 6mm projector, designed from the base up for auditorium and large group purposes, was presented in 19 50 by Eastman Kodak. The unit, delivering considerably more screen illumination than previous 16mm. equipment, was the result of many years of intensive research and development work aimed at producing a unit capable of standing up and delivering consistently high-quality motion pictures under the exacting requirements of daily use. Although reasonably portable, the projector 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 the 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. Individual motors also drive the tlower, take-up 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 10 major components of the projector may, as a result, be easily removed for service. Following standard 3 5mm practice, an intermittent sprocket is used instead of a clawtype, pull-down mechanism. Last year also marked the presentation by Eastman of its first lightweight 16mm sound projector. Termed a trim, convenient and versatile unit, the projector was designed to provide finest quality pictures and sound reproduction, plus ease of setup, operation and moderate price. Named the Kodascope Pageant, it operates without converter or extra equipment of any kind on either alternating or direct current. Extremely compact, it weighs less than 3 3 pounds complete. Both the speaker and the projector itself are built into the carrying case for greater ease in handling and use. The speaker is part of the case cover and can be used up to 3 5 feet from the projector with the cord supplied. The projector is in a tan metallic wrinkle finish. The motor is governor-controlled to provide a constant speed and full lamphouse ventilation at all times. Sound or silent speed may be obtained by simply shifting a lever which positions the drive belt on a stepped pulley. The machine is extremely quiet and smooth running. This has been achieved through the use of a minimum of moving parts. Victor Animatograph Adds 3 16mm Sound Projectors 'JpHE YEAR 1950 marked the 40th anniversary of continuous operation for Victor Animatograph Corp. of Davenport, la., one of the pioneers in the 16mm motion picture equipment industry. High spot of the year was the simultaneous introduction of three new 16mm sound projectors featuring new attainments in ampliflier performance, picture brilliance, operation and beauty. The projectors, designated as the "Sovereign" (Model 60-25), the "Escort" (Model 60-10) and the "LiteWeight, Sr." (Model 56-4), offer many of the Victor projector features in addition to the new innovations. Among these are the exclusive safety film trips, 180 degree swing-out lens mount and instantilt. All three of the new projectors feature Victor's new two-tone, sage green wrinkle finish. Year Is Termed One of Biggest in B&H History J AST YEAR proved to be one of the greatest in the history of the Bell & Howell Co. for the sale of 16mm sound motion-picture projectors. This is taken by the firm to indicate "greater and more extensive use of 16mm films for industrial management, employe relations, employe entertainment as fell as for the education of our youth in the schools and colleges of the country." The increased sale of 16mm projection equipment
