retained and new features added. Among these are: a finer case, tone control and speeds for both silent and sound film operation. The projector can be used on either AC or DC and is contained in a single case measuring approximately 8x12x15 inches, weighing but 24 pounds — only slightly larger than a portable typewriter. The case accommodates, besides the mechanism and amplifier, cords, speaker, an empty take-up and three 400-foot reels of film. The projector retails for $169.50. Concurrent with the presentation of the Model "60" Movie-Mite to the trade, the Movie-Mite Corporation announces that at this date immediate delivery can be made on all Movie-Mite models. Need for supplies and materials was anticipated and the projectors are coming off the assembly lines in quantities great enough to supply the present demand. Radiant Screen Booklet The Radiant Manufacturing Corporation of Chicago, 111., manufacturer of Radiant "Hy-Flect" Projection Screens, has just issued a new folder, entitled "For Clearer More Brilliant Projection — Radiant, the Hy-Flect Screen." It contains full descriptions, sizes, types and prices of the complete line of Radiant Screens for home, business and educational uses. Kalart Automatic Speed-Flash A new Automatic Speed Flash has just been announced by the Kalart Company, largest manufacturer of flash synchronizers and lens-coupled range finders. Fully automatic in that it requires no winding or cocking before use, this synchronizer is of the mechanical type. It lis also a universal Speed Flash, fitting | practically any type of camera having I a cable release socket. It can also be used with miniature focal plane cameras by the addition of a simple adapter. Extremely compact in size, measuring only l'L. inches in length and ' inch in width, the Automatic synchronizer unit itself snaps into the jack terminals of the battery case, requires no cable release and eliminates all wires. An armored, flexible coupling connects the synchronizer to the shutter. The coupling is adjustable fur variations in shutters. In operation you simply press the cushioned release button, setting in motion the inertia rotor which controls the timing cycle, the same basic principle of the famous Kalart Micromatic Speed Flash. Synchronization is unaffected by varying finger release pressure. The Automatic unit may be used with either the Kalart Master or Compak battery cases. With the Kalart Master Battery case and reflector, the Automatic will retail at $18.50 complete. With Compak battery case-reflector combination the price is $14.95. The synchronizing unit only is $10. Kodak Minicolor Prints Enlarged paper prints in full color from 35mm. and Bantam Kodachrome transparencies at sensationally low prices are produced by the Minicolor Print Service just announced by the Eastman Kodak Company. Kodak Minicolor Prints are enlarged from Kodachromes in 2x2inch mounts with standard central openings, and are available in two sizes. The "2-X" size is approximately 21/4x31/4 inches, with rounded corners and no margins, and is priced at 75c per print. The larger "5-X" size affords a print 5%x 7-4/5 inches, and prints are returned in mounts — for horizontals S^&xlO^ inches, and for verticals, 8%xll-9/16 inches, with the central picture-area in either case measuring 5x7 M> inches. The price of these "5-X" Minicolor Prints is $3.50 each. Judged by samples of both sizes which we have seen, the quality of these prints, if made from a good original Kodachrome transparency, appears to be excellent. The "feel" of the print, especially in the smaller size, is similar to that of a high-quality playing-card, strong, attractive and resilient. The print-support or base, however, is stated not to be paper or card, but pigmented cellulose acetate which we suspect may lie coated with a multilayer motiopack emulsion similar to Kodachrome. The makers specifically state that at present the dyes used, while as stable as possible, may in time fade or alter, and the prints therefore cannot be replaced or warranted against change in color. They should be protected from the direct rays of the sun. New Kalart Range-Finder The Kalart Company announces its new model "E" Lens-Coupled Rangefinder which will supplant the present Model "P." The new-model rangefinder embodies the experience gained in the manufacture of more than 50,000 range-finders. It will fit all Speed Graphic cameras, Watson Press Cameras and most film-pack cameras. Streamlined in appearance, the new model has a bigger and brighter image which will enable photographers to focus accurately even under unfavorable light conditions. The range-finder is of the su peri m posed -i mage type. Close working distance has been increased from BV2 feet on the new shorter focal-length lenses which will be of prime importance to those doing close-up work and portraits. Mechanically the new range-finder will have all adjustments internally, simplifying installation and adjustment. The rangefinder is adjustable for all lenses from 10.5 to 16.5 cm. Adjustment permits owners to compensate for tolerances in focal-length inherent in every lens. The new range-finder is stated to have been made practically shock proof by ingenious suspension of the synchronizing mechanism. Price of the Kalart range-finder remains at $21, plus nominal installation charge. Bell & Howell Bows Minislide Projector Featuring forced ventilation and a new system of lamp-mounting, the Filmo Slide-master projector for 35mm. minicam slides in 2x2-inch glass or paper mounts, marks Bell & Howell's entrance into the minislide projector field. Though extremely light and portable, the new projector seems clearly intended for use in fields where maximum brilliance or extremely large screen-sizes are wanted. It makes use of a newlydesigned "base-up" lamp which, unlike most projection-globes, is designed to burn in a base-upward position. This, according to B'ell & Howell engineers, permits several advantages. The globe is slid more easily into the top of the lamphouse, and in addition, burning in its inverted position, the blackening de posit formed during operation of the lamp is not deposited on the side of the globe, where it would reduce light-transmission, but is carried upward and deposited on what would normally be the base. Thus it is claimed the side-walls of the new lamp are kept deposit-free for the entire burning life, permitting full illumination to reach the screen at all times. The new lamp retains the familiar Bell & Howell pre-focusing. pre-aligning (Continued on Page 450) American Cinematographer September, 1941 439
