Advances in Cryogenic Engineering

With the 1975 Cryogenic Engineering Conference this se ries enters the third decade of presenting the latest advances in the field of cryogenic engineering. The 1975 Cryogenic Engineering Conference also marked the first time the meeting had been held outside the territorial limits of the United States. Based on the enthusiastic response of the attendees and the exemplary hospitality of the Canadian hosts, it certainly will not be the last meeting to convene beyond the confines of the fifty states. The Cryogenic Engineering Conference Board is extremely grateful to The Royal Military College of Canada and Queen's University for the invitation to hold this meeting in Kingston, Ontario, Canada. The assistance of A. C. Leonard and his staff added immeasurably in making this visit to Canada both a pie asant and a memorable one. The 1975 Cryogenic Engineering Conference was the first meeting of this group on the new biennial conference schedule. Since the last conference in 1973, the Western Hemisphere has experienced the impact of various energy shortages. Thus, it was appropriate that the theme "Cryogenics Applied to Natural Resource Management" for this Conference was not only timely but also an opportunity for the scientific community engaged in cryogenic activities to review the role of cryogenics in meeting these new challenges and problems facing the energy-deficient nations of the world. The Cryogenic Engineering Conference was also pleased to have the Interna­ tional Cryogenic Materials Conference join them in this meeting.
