International projectionist (Jan-Dec 1947)

hibited at the meeting were the following : DeVry Corp. showed a full line of amplifiers, speakers and projectors, in addition to their new Hypex weatherproof outdoor speaker and their in-car speakers. Kollmorgen Optical Co. had a swell display featured by a cut-away showing in detail the construction of their new F:1.9 Super Snaplite lens. Emphasized were the one-piece mount, the anodized finish, and the all-aluminum construction. Baldor Electric Co. displayed their new Rect-o-Lite rectifier which features no moving parts and two 7-point control dials for quick regulation. Blue Seal Cine Devices exhibited the new Model A projector, described in IP last month. Kni-Tron showed various rectifiers, including a portable model designed to save space in the projection room. Ballantyne Co. displayed a full line of Royal Soundmaster sound systems for all types of theatres, in addition to projector bases, amplifiers and a new 40-65 ampere Suprex arc lamp. Jim Elderkin, of Forest Electric Corp., showed for the first time publicly a complete version of his new Electronic Arc Lamp featuring hairline control of arcfeed. GoldE of Chicago offered a line of spots, including the Rotachrome featuring six continuous color changes. Altec Lansing's pride and joy, the new "800" Voice of the Theatre Speaker for houses up to 1000 seats, grabbed top honors in that section. Also shown were amplifiers and a complete line of speakers for every theatre classification. Century Projector Corp. again had the most novel projection display via a stripped-down version of a head moving so slowly as to clearly show the action of the intermittent. Complete "Master" sound systems were also on view. Fontaine Mfg. Co. showed a Q Marker with built-in stainless steel scribers designed to completely eliminate film mutilation. Lloyd Mann on of San Francisco (Local 162), head of Control Engineering Corp., demonstrated on a standard projector operating setup an improved and beautifully-finished version of his Safety Control providing for instantaneous positive cut-off action of the film. (This unit has been described in detail in IP.) J. E. Robin, Inc., displayed the RobinImperial rectifiers and generators, the former being a sixphase job featuring control of the D.C. in 2-volt steps. Oscar Neu (Neumade Products) must sell everything but the theatre walls, judging by his display and voluminous literature. He featured the new Firetite Cabinet for 2000-foot reels which, built like a vault with a lV^-iuch double wall of heavy gauge steel, resists flame completely. Motiograph again scored both on the exhibition floor and in their private quarters. Downstairs they showed the complete bne of Mirrophonic sound systems in addition to the new AA projectors. Upstairs the Motiograph quarters took on the aspect of a branch of the LA., there being so many Local business agents and other projectionists always present as to suggest a national convention quorum. The LaVezzi boys from Chicago displayed a beautiful line of projector parts and patiently explained again and again, even to the non-technical folks, the how and the why of precision workmanship and its bearing on good screen results. These fellows gained themselves a host of friends. Nu-Screen Corp. was represented by Stanley Hand, who related the fine points of this new curved screen. Essannay Electric Mfg. Co. (the late Larry Strong's outfit) exhibited the Strong Zipper changeover, a new reelend signal which, not touching either film or reel, can be used with either 4or 5-inch reels, and the all-purpose film splicing agent Film-Weld. This exhibit was in charge of Miss Milly Markert. The Wenzel Company gave "Ace" representation to their projectors and complete line of projection accessories. A very useful parts catalogue, distributed at the convention, may be had by addressing 2507 So. State St., Chicago. Ashcraft Mfg. Co. had on hand the brand new C-70 Suprex projection lamp designed for wide-range operation from 40 to 65 amps. With a cast aluminum housing, all working parts outside the housing, precise control by means of a novel duplex clutch, and many other operational features, this unit induced much favorable comment. Manufacturers Machine & Tool Co. displayed the new flickerless 35-mm projector which may be operated on either A.C. or D.C. Running at 1880 r.p.m., the novel drive and gearing arrangement of this unit reflects fine engineering skiU. Always worth while, this joint TESMATEDPA is building up year by year to a point where it will be practically compulsory for the alert technician to attend in order to keep abreast of current developments. IP considers these meetings one of the finest things that ever happened in the equipment field, reflecting great credit on the sponsors. This report would not be complete without a bow in the direction of Roy Boomer whose secretarial chores continue throughout the year and whose efforts contribute vitally to making these meetings so eminently successful.
