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.
y^rPh?hTTT^ll~jJi|]^ THE COVER—This color photo- graph of various phosphor applications was taken in a dark room with "black light," i.e. ultraviolet, to excite the phosphors. The large letters are cardboard coated with phosphors; the glass bottles and two series of glass vials contain phosphor crystals; the oscillograph panels are phosphor-coated by the silk screen process; the small RCA emblems are phosphors enamelled on iron plates, and the discs and knobs are trans- parent plastics containing embedded phosphor crystals. .\11 of the phosphors shown are derivatives of zinc sul- phide.
