Motography (Apr-Dec 1911)

82 MOTOGRAPHY Vol. V, No. 5. While the apparatus hereinbefore described, has been adapted to existing machines, it is evident that many minor modifications could be made in the apparatus without departing from the spirit of my invention. I claim — 1. In a kinematographic apparatus the combination with a vertically slidable support, of an objectiv mounted 'v said su port, a shutter mechanism supported by said support and movable horizontally in relation to the objective. 2. In a kinematographic apparatus, the combination with an objective mounted on a slidable support, of a bracket secured to the said support, comprising a pair of arms having telescopic connection, one of said arms carrying a rotating shutter, means for rotating said shutter, telescopic connection between said rotating means and shutter whereby the shutter may be adjusted horizontally in relation to the objective and to the rotating means. No. 983,139. Manufacture of Filaments, Films and Other Cellulose Products from Cellulose Solutions. Rudolph Homberg, Charlottenburg, Germany. Mr. Homberg claims a celluloid product more transparent, stronger and softer than the films heretofore known. In his patent, he says : It is well known, that artificial filaments, films and other cellulose products are produced from cuprammonia solutions of cellulose. I have discovered, that the filaments and other products thus obtained are considerably more valuable, if an aldehyde or a compound of the same, such as formaldehyde, is added to the cuprammonia solution of cellulose before it is spun into threads, for instance by adding 10 per cent of a 40 per cent formaldehyde solution to the cellulose solution produced in the usual manner. By this treatment a chemical change occurs in the solutions themselves, as can be easily recognized by the fact, that the solutions, when poured out on a plate and allowed to dry, leave clear transparent films or layers, while the same solutions without the addition of formaldehyde form milky opaque films. The new products differ from those produced in exactly the same manner from solutions free from aldehyde by a softer touch, greater clearness and greater strength. Moreover, their resistance to water is increased, although to a less degree. What I claim is : — 1. The process for the manufacture of filaments, films and other cellulose products from cuprammonia-solutions of cellulose, which consists in adding to the said solutions an aldehyde and then treating them further in the usual manner. 2. The process for the manufacture of filaments, films and other cellulose products fvom cuprammonia solutions of cellulose, which consists in adding formaldehyde to the said solutions and then treating them further in the usual manner. No. 983,355. Emergency Exit Lock. H. H. Dupont, Indianapolis, Ind., assignor to Von Duprin Fire Exit Latch Company, of same place. An improved detail upon the type of emergency lock in which a pressure upon the door from the in 983,355. side will cause the door to unlock. The illustration shows the general assembly of apparatus ; a pressure against the horizontal bar near the middle of either door will unlock the door. Check Baby, See Show Aggressive managers of 5-cent theaters in the suburbs of Chicago, those that cater to the "home folks," recently discovered that many mothers would attend the shows but for the seemingly insurmountable obstacle of restless babies. The infants not only annoyed their mothers, but everybody else. Also, there was no means of caring for the gocarts and the mothers did not appear willing to carry healthy babies to and from the theaters, then hold them during the entire performance. Therefore the managers hit upon the simple scheme of checking the go-carts and, when the weather is pleasant and the infant willing to sleep, the youthful passenger as well. The result is that the open air checkrooms in front of the theaters now show long lines of baby vehicles of all sorts and varieties, while the theaters contain large audiences of mothers. One of the arguments in favor of the plan is that it offers mothers who heretofore have been tied to their homes by babies that failed to appreciate the opportunities of the 5-cent theaters a chance to find needed rest and recreation. Moreover, it offers an open air resting place to the babies. At the Janet Theater, 617 West North avenue, the novel plan is found to be working to the great satisfaction of everybody concerned. At the close of the performance the owners of the baby carriages and babies step out upon the sidewalk, checks in hand, just as do the owners of automobiles who attend grand opera. "Number four-eight-one," bellows out the check man, just like a theater door man. Then a uniformed youth seeks out the carriage, removes the chain that holds it and the mother departs. "It's a great scheme," said Harry Hyman, manager of the theater. "There is no extra charge for the checking and we are mighty glad of the opportunity to accommodate the mothers to whom we cater." Sunday Shows for Xulsa, Okla. At a meeting of Tulsa picture show men recently, they discussed all phases of the issue of Sunday performance, and some very strong arguments favoring the Sunday performances were advanced. They all decided to eliminate electric pianos and unnecessary noises, to devote their performances to picturing travel scenes, Bible stories and historical events, among them a series of American history stories now in preparation by the Thomas Edison Company, showing the striking incidents of our history from the days of '76 to the present. This, it is believed, will go far to silence the objections of those who are against moving picture shows, for such shows will do much toward making a pleasant, unharmful Sunday afternoon for the laboring man. This will mean that the working man and woman, the people who have no other time to relax and who have little money to spend at any time, can have harmless, in fact, instructive, entertainment for themselves and family. In this connection it developed that the police department will welcome the continuation of the Sunday picture shows, for the records of their department show that since Sunday picture shows have been going fewer men and boys are arrested for drinking and loitering around places of bad moral repute. This phase, it is believed, will go far toward inducing a deserved endorsement of their side of the problem.
