SHOWMEN'S TRADE REVIEW, October 15, 1949 E-17 Flood of New Projection Aids Presented at TESMA Exhibit (Continued jrom. Page E-1) turer, is to reduce aperture temperature from 1350° F. to 450° F., using a high intensity arc lamp at 70 amperes with no film in the aperture. The manufacturer further states that with this method of cooling test loops of film have been run through the aperture for more than 3,000 revolutions without showing any sign of film damage. Projection lenses of the latest types were presented by KoUmorgen Optical Corporation, including their sealed-construction, six-element, coated f/1.9 Super-Snaplites. The recently reorganized Projection Optics Company, which is now under the presidency of Fred E. Aufhauser, also exhibited a full series of projection lenses; and Bausch and Lomb put forward their new Super-Cinephor and Cinephor series. Motor-Generators and Spotlamps The large and varied display of Motiograph. Inc., included their very new Hipower motor-generator sets, with output ratings ranging from 70 to 230 amperes; the smaller model being vertically mounted to reduce the amount of floor space occupied. The manufacturers claim that these generators are available at prices equivalent to current prices for rectifiers of comparable amperage rating. J. E. Robin and Co. showed an entirely new model motor generator with the motor mounted above the generator and coupled to it by belt drive, again requiring a minimum of floor space. Capitol Stage Lighting Co. had on exhibit an entirely new 1,000-1,500 watt incandescent spotlamp, complete with fingertip control of six gelatines and fadeout dowser, iris, and masking shutter. Murch Electric Corporation showed a small incandescent spotlamp; and also presented the latest Murch factory-built glass projection port, which permits glassing in projection ports with optical glass, coated or uncoated as desired, without need for having the frames tailor-made to order. Projection Accessories Ace Electric Manufacturing Co. demonstrated a new reel-end alarm in which only a harmless ball-bearing comes into contact with the film; a_ new film splicer which can do perfect work on shrunken film because the pins are adjustable, and a new dry scraper for removing film emulsion for splicing. Neumade Products Corp. offered a new wire brush film scraper, for effective removal for splicing not only of the emulsion but also, the manufacturer asserts, of the binding layer that holds the emulsion to the celluloid. It was developed in cooperation with Eastman Kodak Co. LaVezzi Machine Works showed a new line of removable film trap doors for three models of Simplex projectors — the Standard, Super and E-7. Wenzel Projector Co. exhibited new. improved projector magazines. Edward H. Wolk showed a completely new film cabinet in which each section, when a reel is inserted, becomes an independent self-closing and self-locking unit. Kneisley Electric Company presented an improved line of arc supply rectifiers and completely enclosed rectifier switches in which burning of contacts is reduced because oxygen is excluded from their enclosure. Continental Electric Co. put on display an expanded line of photo-cells and rectifier tubes. Acousticon Division of Dictograph Products, Inc., returned to the theatre hearing aid field for the first time since the war with a booth at this Tesma exhibition. And 16-mm. projection was represented by Victor Animatograph's new Envoy model sound projector, and their Auditone two-way speakers which are manufactured by Altec Lansing and utilize 15-inch cones. Three More Fremont Floor Tiles Fremont Rubber Company has added three new colors to their line of floor tiles — a bright red, a verdi-green and canterbury blue. The addition brings the Fremont line to a total of 10 standard, 7 de luxe, and 3 grease-proof colors.
