Sources of Cryogenic Data and Information(NASA), and civilian product lines. Before 1950, however, there was no centralized US source of cryogenic technology data. The Cryogenic Data Center of the National Bureau of Standards (NBS) maintained a database of cryogenic technical documents that served the national need well from the mid 1950s

Fifty-Years’ Development of Cryogenic Liquefaction Processesd hydrogen, and liquefied natural gas over that past period. It is confined to those processes of commercial interest, as applied to large-scale production. In all three sectors included in the present review, very significant advances have been made as the result of market forces. The developments

Lessons Learned in 50 Years of Cryogenic Thermometrya temperature scale is needed and its meaning. Next, the basics of a scale definition and a short history of the temperature scales from 1955 are outlined, together with lessons learned in temperature calibration and international standards. Finally, the characteristics of the main types of thermome
