Neiv Vest Pocket Sport Glass of Compact Design with Wide Field from B&L A vest pocket sport glass, of compact flat design, is announced by Bausch & Lomb Optical Co. for use at all outdoor sports or at the opera. The new glass is of three-power and rectangular in shape, designed to afford an exceptionally wide view rather than a high one. This makes it par-i ticularly suitable for all sports, since the width of the field is 452 feet at 1000 yards. The black moulded plastic body in a modern design is 2J/4 inches thick when closed and weighs but six ounces. It comes in a leather zipper case, in buff, blue, green or black and is priced at $19.50. New Slide Library Simulates Leather Volume for Library or Bookshelf A Miniature Slide Library case simulating Florentine hand-tooled leather is now being offered by Bausch & Lomb Optical Co. in either red, green or blue. Resembling a fine old volume, this slide library is suited to grace the library table or bookshelf. It carries 100 slides in arranged cubicles and is indexed on the inside cover. Measurements are: 6V2X 10x21/4, a handy size for the photographer to carry when displaying slides. The new B&L Slide Viewer is also compactly built and may be easily carried. Victor Announces Price Cuts and Two New Sound'On-Film Models Victor Animatograph Corporation, Davenport, Iowa, last month announced substantial price reductions on 16 mm silent projectors. Model 11 Master Projector, formerly listing at $148 complete with case, is now priced at $125 with case included. If 750 watt lamp and fast f : 1.6 lens are desired in place of the 500 watt lamp and f : 1.85 lens supplied as standard equipment, the price is $132. The Victor Model 22 (1600 foot film capacity) has been reduced from $187.50 to $175. This is a "blimp" model which is enclosed in case during operation. Standard equipment includes 750 watt lamp and two-inch f : 1.85 lens. The company also has two new models of the Sound-on-Film Animatophone now in production. A $275 model with five watt output for operation on D.C. or A.C. is known as Model 31. A 14 watt output model known as the Victor 36 is to be supplied in three variations at $345, $365, and $370. Continuous 16 mm Projector Has Advance Feed Principle A NEW 16 MM portable Continuous Projector, which is being placed on the market in both silent and sound models by Victor Animatograph Corporation, Davenport, Iowa, embodies a patented "advance-feed" principle which insures trouble-free performance, and protection against film destruction. "Bugaboo" of continuous projection always has been eventual tightening up of, and the loss of freedom in the film windings in the film magazine or around the film driving rollers. In the Victor continuous model, the film is wound loosely around two large wheels which are driven synchronously by an endless belt, which also acts as a conveyor for the film. The film literally hangs from the upper wheel, which actually carries the film instead of drawing it along. Size and revolving speed of these wheels have been so calculated that the film is fed off slightly faster than it can be taken up by the intermittent. Slack in the film is automatically controlled by alternate starting and stopping of the drive wheel. A film-slack lever, consisting of an arm and roller, rests on the strand of film which is being fed to the intermittent. Excessive slack in the film permits this lever to descend to a point where it automatically disengages the drive member. No more film issues from the magazine until the excess slack is taken up by the intermittent. This in turn raises the slack lever, re-engages the drive member, and the magazine again feeds out film. Usability of the film is greatly increased by a tremendous reduction Top, Argus" new critical focusing enlarging easel, (Page 6, Column 2), and the three neiv 16 mm lenses announced by Bell & Howell this month (Page 6, Column 2) Center Left, the Los Angeles made Srncro-Sound 16 mm motion picture camera, which Ampro will distribute nationally (Pase 7, Column 1); Center Right, the new Argus all purpose copying bench (Page 7, Column 2); Bottom, Argus Model EFS photo-electric automatic speed printer for 2% x 41/i standard printers (Page 7, Column 2).
