that this camera may prove of considerable value in gathering news pictures in such places where tripods are not feasible.4
Continuous Movement Camera and Projector
Work on the continuous movement motion picture film through motion picture machines has of late shown considerable progress.
In the motion picture machine a running film has been translated into a fixed picture on the screen and this machine is now being prepared for production.
A high speed camera involving this principle of continuous motion has been perfected in which pictures were made this summer at the rate of 1600 exposures per second. Orders have been placed for machines of this character for the solution of problems requiring high speed cinematography.
It is reported that the successful solution of the continuous motion picture problem means safe and practical motion pictures for the home. This apparatus consists of pictures arranged peripherally on a plurality of lithographed paper discs fastened together in the center. A 12-inch record 9/16 inch thick containing the equivalent of 1000 feet of standard motion picture film, the picture on the record being the same size as standard motion picture frames. This machine also is being put in shape for volume production. The machine itself resembles a Victrola and the pictures produced are about four feet wide.
This same principle is also being used as a direct-reading ground speed meter by the United States Navy.
Progress has also been made by Mr. Jenkins in the development of prismatic ring camera projector. This principle is being used in a Stroboscope for direct vision view of rapidly moving objects. By the use of a proper speedometer attachment it is possible to give a direct reading of the speed of the object examined.
The discs are also being used in the development of mechanism for the transmission of pictures by radio, ultimately motion pictures.5
Film
A new fireproof film6 has been reported as an invention by Gustav Schaff, a Berlin Engineer. Ordinary celluloid films are put through a process of impregnation which renders them absolutely uninflammable. Fire makes them melt but they do not burn. An experiment reported shows a fifty-foot reel of film thrown into an open fire and left there for a certain time with only a few inches melted, the rest remaining intact. The experiments have shown that the impregnated films were no different from the ordinary films in other respects.
Emulsion
New high speed emulsion film has been placed on the market by the Eastman Kodak Company which the Committee hopes will be described in detail by Mr. Blair.7
