The motion picture projectionist (Nov 1930-Oct 1931)

26 Motion Picture Projectionist May, 1931 Ultra-Violet Light Source T N THE November, 1930, issue ap peared an announcement of a newtype lamp developed by Dr. J. W. Marden of the Westinghouse Lamp Co. Following a general description of this lamp, the following comment by Samuel Wein appeared: Just why such a lamp cannot be used as an exciting lamp is the concern of the present article. It seems logical that any source of illumination so rich in ultra-violet rays, and with such a low rating, would find immediate application to sound motion pictures, particularly as an exciting lamp. It will be remembered that the greatest flow of photo electrons are had on exposing the photo-electric cell to a rich source of ultra-violet rays. Such being the case, a larger number of photo-electrons ought to flow as the result of exposing the cell to the lamp devised by Dr. Marden. A decided advantage of a greater photo-electron flow is that less amplification would be necessary, and, accordingly, less distortion would result. Concerning which the following observations have been received from A. R. Dennington of the Vacuum Device Department of the "Westinghouse Lamp Co.: A copy of some comments made in the November issue of Motion Picture Projectionist has just been brought to our attention. The suggestion has been made in the publication that a low wattage ultraviolet glow lamp might possibly find use as an exciting lamp for sound motion pictures. A lamp of this type will probably not be of any advantage for this particular service because the ultra-violet rays would be absorbed very largely by the film and the remaining ones would be almost completely absorbed by the glass envelope of the photo-electric cell. In order to utilize the ultra-violet source it would be necessary to install a special photo-electric cell sensitive to ultra-violet; and any device of this kind gives a smaller photo-electric current than the usual gas-filled or vacuum type photo-electric cell. Therefore, at the present stage of development of photo-electric or photochemical devices there would be no advantage in using the ultra-violet source. Old Melies Films Stolen Jean A. Le Roy, one of the pioneers of motion picture projection and a man who figured prominently in the early formative days of the International Alliance, requests publication of the following notice which he has sent out anent old Melies films: It has come to my knowledge that certain persons are endeavoring to dispose of the negative and positive prints of certain issues of the famous "Star" films, produced by George Melies, of Paris, France, in whom title to which still reposes and which were originally in the custody of Jean A. Le Roy, of New York City, until about 1920, when they were stolen. This will advise you that the rights and title to said films have never been sold, exchanged or otherwise disposed of by the owner, George Melies, whose legal representative and agent in America is Jean A. Le Roy and that prompt action under due processes of law will be taken to recover same and prosecute any one in whose custody the films may be found. Any effort to purchase, distribute, or exhibit said Melies "Star" films will be subject to the penalties prescribed by law. This does not concern the Western pictures made by Gaston Melies, and for a time the American representative of George Melies, but only to the aforesaid "Star" films made in France by George Melies, title to which has never been transferred, sold or otherwise disposed of by him. "Superior Craftsmanship" Under a similar heading there appeared in the April issue an editorial which set forth the necessity for constant education and which included reference to the progress being made in educational work in other crafts. This editorial elicited the following initialled comment from C. W., New York: Your comments on "Superior Craftsmanship Pays" in the April issue are an insult to very member of the I.A.T.S.E., not only because you question the ability of these men but also because you cite in substantiation of your statements the progress attained by the electrical tradesmen. Your statement: "The I.B.E.W., generally regarded as one of the outstanding organizations of any type in the world subscribes wholeheartedly to the viewpoint that their men should get the work not merely because they are organized but because they are better craftsmen. And the I.B.E.W., let it be said, is getting results"— this statement implies that I.B.E.W. men are not only better craftsmen than are LA. members but that they (I.B.E.W. members), should get our work. Even if you defend yourself by stating that you meant nothing of the sort but merely used the I.B.E.W. as an example of a group of modern craftsmen, you. who certainly are in a position to know about and understand prevailing conditions, should never have permitted yourself the liberty of making such statements. Quite aside from the fact that we received many complimentary references to this particular editorial (the writers of which would probably incur the displeasure of the craft if they were exposed) , and the fact that explicit mention should have been made of the type (electrical), work which the I.B.E.W. solicits and gets, the editorial as written still represents our opinion. "Prevailing conditions" should not and do not impose any restriction on an honest expression of opinion; on the contrary, they rather make necessary such comment. Furthermore, outside of one or two big centers, no craft other than the LA. has enough men qualified as competent projectionists to occasion serious concern. statement of the ownership,, management, circulation, etc., required BY THE ACT OF CONGRESS OF AUGUST 24„ 1912, of MOTION PICTURE PROJECTIONIST, published Monthly at New York, N.
