Tri-Purpose Projector with three times the illumination of the present Model CC has just been announced by the maker — the Societ.v for Visual Education. Inc., Chica{;o. The new Tri-Purpose unit — the Model AA — has a 300 watt lamp to provide greater power for long throws in large classrooms and auditoriums. Like the Model CC. the AA serves three purposes. It shows (1) single frame film strips (2) double frame film strips or (3) individual frames (color or black and white) mounted between 2" x 2" glass slides. The new S.V.E. Rewind TakcUp, which rewinds in the proper sequence each roll or strip of film as it is being shown, is standard equipment for the Model AA. The film, instead of dangling on the floor, goes into a special take-up can and is thus fully protected against gathering dust, lint or finger marks. This feature makes the AA particularl.v .suitable for use in schools, clubs and churches in showing professionally-made film strips or film-slides as well as film strips made with miniature cameras by members of the organization. The Model AA Tri-Purpose Projector, complete with lens, lamp. Rewind Take-Up, double slide carrier and carrying case, retails for $57.50. The model CC, complete with lamp, lens, double slide carrier and case but without the RewindTake-Up. retails for *.S5.00.

The great "bugaboo" of continuous projection alwavs has been the eventual tightening up of and the loss of freedom in the film windings in the film magazine or around the film driving rollers. If a string is wound loosely around one's finger, it will gradually tighten up if one or both ends are pulled. Film in a continuous projector is bound to do the same thing unless it incorporates the "advance-feed" principle, as in the Victor. The backbone of this principle is the positive regulation of the amount oj film jcd to the intermittent film-moving member oj the projector. By eliminating all pull and strain, the new patented "advancefeed" insures perfect freedom from operating troubles caused b,v film destruction or binding of the film in the magazine. Of equal importance is the fact that the usability of the film is greatl.v increased b.v a tremendous reduction in surface rub or friction between layers of film. The film literall.v winds and unwinds itself by dropping into place as it passes over the arc of the wheel. As a consequence, wearing and scratching of the film surface, which occur rapidly in machines that cinch and grind the film together, are minimized by this "free", floating action of the Victor continuous. Added protection against film damage is provided by the Victor automatic film trips which automatically stop projection and film movement in the event film loops are lost because of <lamaged perforations, incorrect threa<ling, or defective splicing. Choice of 500 watt, 750 watt, and 1000 watt projection lamps insures screen brillianc.v of the desired intensity, and a sharp, welldefined image even in broad daylight. The film capacity of standard models of tlie tmit will be 500 feet. Special models with greater capacity can be supplied on order. 36
