1969 marked the return of the Cryogenic Engineering Conference, now affiliated with the National Academy ofSciences through the Division ofEngineering, National Research Council, to the University of California at Los Angeles. As in 1962, the Cryogenic Engineering Conference gratefully acknowledges the assistance of UCLA, its Engineering and Physical Seien ces Extension Division, and in particular J. Dillon, S. Houston, H. L. Tallman, and their stafffor serving as hosts to the 1969 Cryogenic Engineering Conference. The National Academy of Sciences is a private honorary organization of more...

The 1960 Cryogenic Engineering Conference Committee is pleased to present the papers of the 1960 Cryogenic Engineering Conference. Discussion of the papers, wherever available, has also been included to make the papers more valuable and interesting to the reader. This annual meeting once again has been held in Boulder, Colorado. Many delegates will recall that similar meetings were held in Boulder in 1954, 1956 and 1957. However, this year, because of the continued growth of this conference, the National Bureau of Standards Boulder Laboratories was joined by the College of Engineering of the...

The 1959 Cryogenic Engineering Conference Committee is pleased to pre- sent the papers of the 1959 Cryogenic Engineering Conference. We are fortunate to have had the University of California at Berkeley, Ca ., as our host for the fifth national meeting of this kind. The move to the West Coast for this past Cryogenic Engineering Conference was prompted in part by the large concentration of missile activities which are to be found there. Recognition of cryogenic operations and techniques in the mis- sile field is given in many of the included papers. The University of California was certainly...
