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.

To Tell You About Modern Projection
This catalog gives complete information about the new Super Cinephor lenses and condenser system. This projection system is one of the most important developments in motion pictures. It gives better definition than ever before, especially on short focal lengths. It supplies more intense illumination and better distribution of light, due to the new condenser, and therefore gives a more nearly perfect projected image.

Power Rheostats and Potentiometers
Dejur-Amsco power rheostats and potentiometers are engineered mechanically and electrically to provide a consistent and unvarying current control and to give an added degree of perfection in the power control of circuits and systems to which the wire wound variable resistor is adapted.
Engineers will immediately recognize in these Dejur-Amsco variable resistors the solution of many problems in Power Circuits, Mixing Panels, Spot Welding, Motors and in the Photo-Electric field.
Write us your .requirements. Our engineers are ready to assist you in the development of special apparatus to fit your particular needs. Literature on request.
