Abstract
MR PRESIDENT and Gentlemen: I am going to describe to you briefly the result of the work that has covered a period of about ten or eleven years on the part of Mr. S. Bardy, the inventor and patentee of a moving picture machine. This machine has for its principle a continuously moving film, with a sprocket which carries the film an integral part of the disc shaft upon which the lens or rectifying elements, if you will, are mounted at right angles to the plane of the said disc. The light source is in the usual place, the light going through the film, and through the objective lens, and the motion of the film downward through the machine is constantly kept in proper position on the screen by means of this rectifying lens, which we have made at the present time in segments, which are mounted on the outer periphery of this disc. We have done a great deal of work in this connection, covering a considerable period of time, and have projected a picture on the screen that is very satisfactory. There is no transition apparent. I have not made any photometric measurements of any variation caused by the prism influences of the light, but from direct observation there is no flicker at all, either with the film or without the film. I have not prepared any slides or have I any data sheet to put before you, but I merely wish to say there is a machine of that type, and we are going ahead and making our plans to manufacture the machines and put them on the market.
