I Film Expert Endorses Article on Splicing RD. HANISH, General Manager, Rex Film Renovator Manu• facturing Company, Columbus, Ohio, writes : " I wish to compliment the article which appeared in your Projection Department on November 10, regards to patching film. I used to be manager of the old Buckeye Film Projecting Company, which originated in Dayton, Ohio, in 1909, consolidated with the Cincinnati Film Exchange, and moved office to Columbus, naming the exchange the Buckeye Lake Shore Film Company, and then sold out to the Mutual Film Company. I instructed all of our inspectors to make patches as described as proper by your Projection Department. " The write-up given in the above issue was a dandy but did not exactly show all the faults if a patch is made with the entire sprocket. When a full sprocket is used for the patch, in endeavoring to scrape the emulsion from the film the inspector is too careful of scraping too hard on the edge of the film where sprocket hole is located and will not clear away the emulsion entirely. By lieglecting to remove all emulsion completely across the film, the cement will not adhere or will not weld firmly. " The writer in his many visits to the various exchanges throughout the country finds that wherever they use patches as condemned in your illustration the middle of the film is firmly welded, but both sides of the film of the patch are loose, and when a film patch is made with both sides loose, the edges do not hold firmly and is the cause of the sprockets pulling greatly. " I have hammered at managers of exchanges, especially in film departments, that the condemned patch (loc. cit. Fig. 1) is not the proper patch to follow or to instruct anyone to make, but it is like talking to a brick wall, and I think for the benefit of the film industry that the illustrations given should be run from time to time, not only to impress upon the exchange the proper patch, but for the operators throughout the country in general. It will succeed and be a great benefit to your National Anti-Misframe League. " Have also noted many of your film cement recipes in your Projection Department and have no reason to condemn them, but I have a film cement formula, which I am enclosing, and we have published this in our catalogues for many years and the exchanges that have adopted this cement claim it is the best they have ever used. Have some of your inquirers for a good film cement formula try this." Comment: Mr. Hanish brings up some practical points which were rather outside the scope of our article, which, as its title ("The Mechanics of Film Splicing") indicates was descriptive of the purely mechanical strains on film splices in their passage over the sprockets of a projector, and the elimination of these stresses by the use of a form of join which would be a mechanical fit around the teeth of a projector sprocket. We intended to dwell at a later date on the actual technique of the splicing operation, such as scraping, cementing, pressing, etc., but some of these points are well emphasized in Mr. Hanish's letter. In view of some of the film splicing which we have seen we believe that it would be well, as Mr. Hanish suggests, for the diagrams reproduced in the article mentioned to be widely circulated and closely studied by operators and exchange men, although we can state that prior to the receipt of Mr. Hanish's letter we had already received a number of communications from operators in which they stated that our demonstration was all in favor of the proposed type of splice, and that they had, in fact, often thought of writing in recommendation of the same style of join. A good film cement formula is always of interest and value to operators, and we are pleased to reproduce herewith the one suggested by Mr. Hanish. It is compounded as follows : Collodion 1 part Sulphuric Ether 1 part Amyl Acetate 1 part Accytic Ether 1 part Seattle Hospital Installs Simplex THE Seattle Stage Lighting Company, of Seattle, recently installed a Simplex projector in the Tuberculosis Hospital at Seattle, Wash. The Simplex was mounted on a portable platform so that it can be moved from one ward to another and in this manner each floor secures its own entertainment without interfering with the patients on the others.
