Light-Sensitive Paper

In 1962, soon after we had demonstrated the photofix concept, we still had no good idea what to do with our light-sensitive papers. Our management had little experience in the area, and we were constrained in going outside the company for help, for fear of compromising our patent position. Where could we get help ... 

Make some more light-sensitive paper for the experiment on page 83. Don t make any images on this batch, though. Just soak some index cards in a sodium chloride solution, then in a silver nitrate solution, let them dry in a dark place, and store them in a black envelope. 

Copper nitrate (Cu(N03)2) is used in light-sensitive paper.

Finally, such copying may become necessary also in other instances, e.g., where the recording has taken place on a medium that will deteriorate rather rapidly, as is the case for certain light-sensitive paper records. However, these copies should represent truly accurate copies of the original, with no corners or edges cut off thus they have to be verified, normally by dated signature of the person who did the copying.

This test essentially consists of displaying the electrical activity of a living muscle using an intramuscular wire electrode which is placed transcutaneously on the intended muscle. This signal can be converted into a sound and played to a loudspeaker it can be stored on magnetic tape or printed out using electronic printer or light-sensitive paper. 

The machine contained a mechanical printer, which recorded the analysis data on the unexposed area. This approach resolved a serious problem in the medical analysis field the transmittal and accurate transcription of information. This application consumed considerable amounts of light-sensitive paper. Originally the images were cyan, but as the xerographic printers of the period had difficulty coping cyan images, a blue-black leucodye was subsequently incorporated in the recipe. For many years, the aca paper represented a lucrative market.
