THE MOVING PICTURE NEWS 23 screen between the condensing lenses, said screen consisting of a transparent receptacle containing distilled water which eliminates the excess of heat from the projecting light ray. The object of the invention set forth in Letters Patent No. 1,063,081, issued to Charles H. Converse and William H. C. Rider, of Chicago, 111., is to provide an improved heat-arresting or protecting screen between the light and the film of the picture apparatus, for the purpose of deflecting or absorbing the heat rays, or a sufficient amount of the heat from the light, to prevent the temperature of the film from rising to a dangerous degree; and to provide an improved heat-arresting and color screen, through which the light may be projected to reproduce the pictures in various colors, tints, or shades. The diagrammatic sectional elevation of a picture-projecting apparatus comprises the usual lamp house B, arc light A, condensing lens C, and shaping tube D, while G represents the kinetoscope or moving picture machine, having film reels F, for carrying the film K and the projecting lens L, all of which may be of the ordinary well-known construction. A sheet E, of transparent celluloid, cellulose, fibroid, or similar material is interposed between the lamp and the film, thus absorbing the heat rays which affect such celluloid material, and rendering the use of the celluloid film perfectly safe. This sheet of celluloid is located near the point where the light emerges from shaping tube of the lamp house, at which point the circle of light is about three inches in diameter, covering an area of over six square inches, or many times greater than that at which the moving picture film is exposed. As the heat rays are thus spread over such a large area of the celluloid screen, the temperature of the screen at no time rises to a dangerous degree, even when exposed to the light continuously, consequently there is no danger of the screen taking fire, and the film is safely protected from the heat. H is a series of colored celluloid screens any one or more of which may be interposed in the projected light between the lamp and the film, for the purpose of protecting the film, and giving any desired color, tint or shade to the picture. A process for recovering the material of the support of Cinematographic films and waste portions of the same, is the subject of Letters Patent No. 1,065,115 issued to Henry Danzer, of Paris, France. It consists in depriving used, unsold or other films of their gelatin for the purpose of recovering. 1, the metallic silver of the pictures; 2, the material forming the support without occasioning any alteration of the said material. For this purpose preparations containing soluble proteolytic ferments (pepsin, trypsin, papain or the like) or living ferments (liquefying bacteria and the like) are used. For example, the films to be treated, comprising the celluloid bands or supports coated with the insoluble gelatino-bromid emulsion, are plunged into a diluted solution of commercial trypsin, heated to a temperature of about 40 degrees Celsius; in this case, the solution will be efTected very rapidly owing to the fact that the trypsin converts the gelatin into peptones which are readily dissolved in cool or tepid water. The solution terminated, the material of the support (in the form of bands) will be washed for the purpose of removing all kinds of impurities and the metallic silver (or in the form of a salt) will be carefully collected. Registration No. 92,376 has been granted the Societe Anonyme des Celluloses Planchon, of Lyon, France, for "PLAVIK" as a trade-mark for photographic papers, films, plates, photographic apparatus for making negative blocks, enlargers, and parts thereof, dark backs, plateholders, objectives, instantaneous shutters, tripods, photographic printing frames, cameras, apparatus for taking and printing stationary and animated views, spool-films, film-packs, stiff films, stereoscopic films, cinematograph films, photographic draining racks, photographic print and plate washers, photographer's compasses and exposure meters, and photographic lamps. Mark used since October, 1911. A recently invented machine is designed to clean and render good as new if^"^ I "rainy" films even after sixty days' use. Now let some one evolve means that will automatically eliminate incongruities and render the film innocuous before use. Even in the film consistency is a gem of purest lustre, while "a laugh costs too much when bought at the expense of virtue." On the English estate of Dr. Francis Ward are several pools teeming with aquatic life, each provided with a subterranean observation chamber. Because of the darkness in the chamber and the light in the pool, the glass front of the chamber acts as a mirror in which the fish merely see themselves and their surroundings reflected, while the observer can plainly see into the pool and take motion pictures or snapshots of water life. It is thus possible to watch and "take" even the most timid of fish without disturbing them. To familiarize the fish with the rattle, a novel contrivance which produces a continuous sound not unlike that of a motion picture machine is used. Professor Dussard has been turning his ^ attention to the production of a motion picCfl^y ture apparatus for the blind, by means of which they may experience the illusion of ^ |\ moving objects as people with full powers I do in viewing an illuminated screen. The device mainly employed for educational purposes consists of a machine operated by electricity which causes a series of reliefs to pass rapidly under the fingers, the reliefs being so graduated that the delicate sense of touch of the blind translates their variations into apparent movements of the objects which are represented. There are three permanent motion picture theatres in Shanghai, China — the Apollo Theatre, Victoria Music Hall, and the Cinema, Paris. During the summer months, when weather conditions permit of open-air entertainments, temporary stages and curtains are erected in parks and open spaces and motion picture shows set up, which are fairly well patronized. We shall be pleased to answer pertinent questions propounded by readers of The Moving Picture News. A new member of the Vitagraph Stock Company has already attracted considerable attention in her appearances in Vitagraph life portrayals. Miss Louise Beaudet, who has been for many years prominent on the professional stage, is now proving a competent «nd unusual artist in moving pictures. "Things are coming along pretty nicely for "Ramo," says C. Lang Cobb, Jr., manager of sales and i)ublicity. This is demonstrated by the fact that C. Lang has discarded his cane and rides about town in his new automobile.
