Advances in Cryogenic Engineering Proceedings of the 1957 Cryogenic Engineering Conference, National Bureau of Standards Boulder, Colorado, August 19–21, 1957

By popular request, the National Bureau of Standards was again a host to a conference on cryogenic engineering on August 19-21, 1957. Similar meetings were held here in 1954 and 1956. The acceptance of over forty papers for this conference was certainly a sign of the increasing activity and interest in this engineering field. There seems little doubt that it will continue to grow, justifying the need for annual meetings. To make the Proceedings more interesting an attempt was made to include as much as possible of the general discussion which followed each paper. To obtain individual reprints of anyone particular paper, please contact the authors directly. 1957 CRYOGENIC ENGINEERING CONFERENCE COMMITTEE B. W. Birmingham National Bureau of Standards S. C.
