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.

If you wish further information on the DuMont line we*d suggest you write direct for their catalog or their color planning packet which is also available. The State University of Iowa is conducting a "Short Course" on color television to be held on April 1 $ and 16, Attendance is expected to be around fifty, composed of chief engineers and production managers of nearby TV stations, TV repairmen, stu¬ dents and faculty of the University, The announcement reached us last week, too late for us to make plans to attend. Looks like an interesting and informative pro¬ gram. Professor Edward M. Lonsdale of SUI*s E. E. Department is Chairman of the conference. We*d like also to mention the General Precision Laboratory Model PB-610TV Pro¬ jection system which was demonstrated at the TV Engineering workshop last October. It projects a picture up to 9 x 12 feet in size, is wheel mounted for mobility, and was designed for group viewing in schools, hotels and industrial organizations. It can be used either for closed circuit programming with studio or industrial cameras or for viewing "off the air" broadcasts by the use of the TV receiver incorporated in the unit. Systems of this type should be of great value to educational institu¬ tions especially in medical or dental schools. The most minute details of surgical operations can be picked up on a TV camera and fed to almost unlimited numbers of viewers located in local or remote auditoriums. Industrial plants too can demon¬ strate complex machine shop operations to large groups of personnel concerned. For more complete information,including price, write to General Precision Lab¬ oratory, Pleasantville, New York. We had a recent request from M. McCabe Day, Director of the Audio-Visual Cen¬ ter, Station WVSH, Huntington, Indiana, asking for information to enable them to build a 2^0 watt amplifier for their 10 watt FM transmitter. Lacking this we told him of two stations with 25>0 watt FM transmitters for sale. Perhaps one of our read¬ ers has the information he wants or has equipment for sale. If so, we*re sure he*d be interested in hearing from you. March 8 and 9 we spent at the TV Laboratory, State University of Iowa at Iowa City. We met the entire staff, observed their operation and reported these obser¬ vations back to them. We hope that our recommendations and suggestions will prove of value to them. They are conducting an experiment at the TV laboratory in Iowa City to study the effectiveness of the discussion method of teaching when transmitted from one room to others by means of television. Dean Dewey B. Stuit of the College of Lib¬ eral Arts is in general charge of the project and the class meets in the TV Studio. But since we*re already late we*11 give all the details in the May Newsletter .
