THE MOVING PICTURE NEWS 25 Patent No. 1,039,212, to W. L. Sullivan, of Ferguson, Mo., assignor to the T e m c o Mfg. Co., of St. Louis, jNIo., a corporation of Missouri. This invention relates to ticket vending machines, the principal object being to provide means for unwinding a sufficient number of tickets from the ticket roll to slacken the ticket between the ticket roll and the feeding drum, so as to prevent the pins borne by the drum from tearing or mutilating the tickets during the operation of feeding same from the machine The accompanying view represents a side elevation of part of a ticket-vending and registering machine with the unwind means attached thereto. additional marry-time disaster. "Dower is the widow's last plank in her shipwreck." ( Engle v. Engle, 3 West Virginia 346). Then, to follow the simile, to marry a widow is to rescue a shipwrecked mariner on the sea of matrimony, and possibly to precipitate an Patent No. 1,040,110. issued to Anders Christian Anderson and Lauritz Sophus Anderson of Copenhagen, Denmark, is for a System of Transmitting Images to a Distance, and if it accomplishes all that is claimed for it, it is a wonderful and epochal invention. Not only are images reproduced at a distance, but color and movement are also duplicated. The a c c o m p a nying perspect o-diadram illustrates symbolically the installation collectively, comprising a transmitting station and a receiving station connected by an electric circuit. The circular insert shows an endless ray intercepter in lieu of a ribbon. The upper part of the diagram represents the transmitting station, the lower the reproduction station. These comprise two similar apparatus functioning simultaneous^', their synchronous movements being regulated by electrically actuated clock work interposed in the electric circuit. As in the D'Albe's optophone noted last week, selenium plays an important part in this system, its sensitiveness to light and change of electrical resistance under variations thereof being utilized at both the transmitting and receiving stations. At the receiving station the rays from a scene or object pass through a lens to a rapidly moving ribbon, opaque except at certain perforated points diagonally arranged. These holes are spaced apart in such manner that only one point can be located at each instant within the field of the image in the dark chamber of which the traveling ribbon forms the rear. The luminous rays passing through the perforations in the ribbon are directed by a lens to a prism. The rays of the spectrum are thus produced on a rotating disc. Opposite the spectrum and against the disc is placed a selenium cell. Openings in the disc correspond to the width of each colored band, while their distance apart corresponds to the total length of the spectrum. There is thus only one opening that can be located at each instant in front of the spectrum. The electric current transmitted by the selenium cell actuates an electromagnet at the receiving station, where the rays from a light projector are separated by means of a duplicate perforated traveling screen, and other accessories — the coloration being effected by transparent bands representing the spectrum and worked synchronously with the spectrum wave-transmitting means at the receiving station. The speed of the apparatus employed is necessarily very rapid. Only a general idea of the modus operandi and results claimed can be here afforded as the specification of the patent is very long and intricate, and must be resorted to for details. Used in conjunction with the telephone, it is claimed that it is possible by this means to see as well as hear a person at the other end of the line. By means of an interpreter it will be possible either to see or to talk by employing only the telephone wire. Finally, the apparatus can be employed for verifying documents at a distance, for exhibiting samples, machines and objects in motion, etc. It can also be employed in the army, not to mention passing events and theatrical representations. The inventors claim specifically the method of transmitting colored images to a distance, which comprises projecting an image of the object, point by point, on a selenium cell, separating the rays falling on said cell, as regards their color, projecting rays on a screen in correspondence with the aforesaid projection of the image, varying the intensity of such light rays in accordance with the changes in the selenium cell, and varying the color of said rays in correspondence with the aforesaid separation of the rays. At the banquet of the American Iron and Steel Institute, held in Pittsburgh this week, moving pictures showing the progress of iron ore from the mine to the moulder were displayed. Another evidence of the utilitarian value of the "Movies." They are also becoming of importance as an adjunct to the study of disease, as witness the fact that in Philadelphia recently Dr. Theodore H. Weisenberg, of , the Medico Chirurgical College, exhibited a remarkable series of motion pictures of cases of nervous diseases, to an audience of two hundred physicians and surgeons. The motion pictures were made and furnished by Sigmond Loubin, who is deeply interested in the use of the art for the advancement of science. Judging from the manifest attention and approval bestowed by the public on scientific films generally, it is a wonder that self-interest does not prompt their more frequent projection upon the screen aside from their unquestionable educational value.
