We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.

Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.

24 A. G. ZIMMERMAN presence of the specification enabled us to move into the subject very rapidly in the Cleveland meeting; thus enabling the American Standards Association group to prepare Draft No. 2, which, when attacked in Rochester, proved to be such that Draft No. 3 was not too difficult of preparation. It is my privilege, as Chairman of Z52 D, to report at this time, despite the very strenuous requirements as indicated by the speakers immediately preceding me, that upon favorable action of the parent Committee Z52 on April 22, the specification will be submitted to the Joint Army and Navy Board in Washington for action in a program which will establish the specification as JAN. This will complete our preliminary work in specification preparation on the Class / Projector (incandescent lamp) . Class // Projector, which is primarily to be the same mechanism except for provision for an arc lamp, will be prepared as soon as sufficient information is available regarding some of the design problems involved, as well as the definite decisions regarding the light source. The screen problem has been referred to a subgroup, headed by Mr. A. L. Raven, which is to prepare such information as is available; whereupon a meeting of Subcommittee D will be called to discuss the situation and compile a specification, in conjunction with the Armed Forces. The test films for use in either designing or acceptance testing the Class / or Class // projectors mentioned above were assigned to this Subcommittee. Action taken by the Subcommittee is such that they too can be submitted to Z52 for their approval; whereupon War Standard Specifications can be issued for procurement for the Armed Forces. May I, as Chairman of Z52 Subcommittee D, take this opportunity to express my personal gratitude to those who, either as direct representatives on the committee, or as auxiliary aids in other departments of the Society or branches of the armed service, have contributed to the program which enabled us to complete our obligations with dispatch.
