Modernization Increases Accuracy and Utility of Spectrographic Computer

Volume 7, Number 1 (Feb. 1953) Page 34-36

Adams, M.M.

This report is a brief description of the component changes and product engineering made in the Phillips 66 Spectro Computer since the earlier models were described in a paper by Morgan and Crawford.

The improvements described add greatly to the versatility of the Spectro Computer, as well as make possible approximately a tenfold increase in accuracy. At the same time, the instrument is unitized so as to minimize maintenance problems.
