International projectionist (Oct 1931-Sept 1933)

July-August 1933 lens but the difficulty is that as soon as the sharp edge contrast is lost, the sensitiveness of the test goes down again. Mr. Bliven : May I suggest that the field of test film be limited, to cover specific points at a time. Probably a thousand-foot film would not be long enough for that or perhaps the cost of the films would be prohibitive. Dr. Goldsmith: The Committee had in mind using a vignette with one of the test subjects so that only a portion of the field would be shown, the rest of the field being dark; and letting the person watching the vignette travel around. But difficult production problems would be involved, and more elaborate research than was thought justified. Member: In the early days when the machine had to be taken apart and oiled and cleaned, the obvious way for the operator to adjust the shutters was to place a small flash-lamp in front of the projection lamp and project the beam on the film; and then to set the shutters so that it covered the lens as the pull-down started. In all the years that I used that scheme I never had to use a test object on the screen to see whether I had travel-ghost. Travelghost is caused by the shutters being out of time, and the lens must be closed while the film is being pulled down. It is not difficult at all to set the shutter in the projection booth without using any test object whatever on the screen. I think it is going to be impracticable to use a long reel. If the tests were made on four-foot loops, each one stored in a can by itself, the required test could be selected whenever desired. There Avould be a number of such loops, one for definition, one for aberration, and another for travel-ghost, or whatever the defects happen to be; and one would select the particular four-foot loop needed, and run it for whatever time necessary to adjust the projector.

"Permit Man" Agreement At the commencement of the trial, the cases of five of the plaintiffs were submitted to the Court, it being the intention to submit those cases, which were deemed typical, for the decision of the Court, with stipulations affecting the remaining plaintiffs. Upon the completion of the trial of the cases of the five plaintiffs a motion was made to sever the action as to the remaining causes of action. The motion was denied by the Court and the action proceeded with the introduction of additional proof and additional stipulations. Although in this decision the cases of such five plaintiffs may be referred to, the disposition of their cases will relate to all of the 237 plaintiffs. Stated generally, as relating to these
