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.
Motors: Universal a-c/d-c type whose speed is dependent on supplied voltage. For isolated field use, storage or hot-shot batteries will operate the camera. Standard a-c (50 or 60-cy»le) can be used in the laboratory.
Prism Drive: Simple gear train with ultra-precision gears. The ratio of the driving and pinion gears is one to six.
Lenses: A 4-in. //2.3 lens will be standard on the camera. As has been pointed out, higher overall resolution is obtained with longer focal length lenses. The light is traveling in a more parallel beam. Other lenses available will be:
1-in. //2.3* 35mm //2.3* 2-in. //2.3* 3-in. //2.3 6-in. f/2.7 10-in. //4.5 24-in. 7/5.6 40-in. 7/7 80-in. 7/7

fiducial marking
Feed Spindle: Torque adjustable so that as film speed is altered, best results can be obtained through minor adjustment.
Timing Light: Double lamps provided. One can be used for standard time flash, and the other for event flash. NE66 lamps are used. It has been found that 135 volts will give better results with these lamps.
Viewfinders: Bright field telescopic and tracking finders will be provided.
Modifications to the camera to fill specific user needs will be made on request and to specification.
A camera of this type has long been needed in this country. In designing this camera a large number of factors have been taken into consideration. It is rugged and easy to manipulate. Its good picture quality fills the needs of research and development laboratories, the field, and the newcomers to highspeed photography, producers of entertainment and television.
