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.
November, 1943 Page 347 11 ^ fjl 11117HIHI g ^/te ^<upuuu CHALLENGER can serve in many classrooms. It is light in weight, easy to carry and can be set up quickly anywhere. It is the only screen that can be adjusted in height merely by releasing a spring latch and raising the extension support. (No separate adjust- ments of case). The Challenger's specially processed Da-Lite Glass-Beaded surface shows pictures always at their best. It is especially fine for Kodachrome projection. The DA-LITE ELECTROL is operated entirely by electrical control. Because there is no tugging on the screen fabric when it is unrolled from the case and because the fabric is in its protective case when not in use, it lasts longer than any other type of screen mountings. A LIMITED QUANTITY OF SCREENS R*g. U. S. Pat. Off. CAN NOW BE SUPPLIED FOR Pre-lnduction Training Vocational Training and Other Uses Approved by the W.P.B. jT^OR THE first time since August, 1942, steel can again be used in the manufacture of a limited quantity of screens for certain civilian uses. The current W.P.B. order L-267 supersedes order M-126 which previously had limited the use of steel in screens to only those which were made fcr the armed forces. Those who need Da-Lite Screens should apply to W.P.B. for au- thority to purchase using form 1319, which may be obtained from local W.P.B. ofiBces, Da-Lite visual education dealers, or from us. Orders must be filled in the sequence in which they have been ap- proved. Because the quantity of screens that we are permitted to make is limited, immediate action is necessary. All models and all sizes of Da-Lite Screens will be available in restricted quantities but made to the same high standard of quality for which Da-Lite Screens have always been famous.
