To highlight the occasion the CEC Board, in conjunction with the International Cryogenic Materials Conference ICMC Board, proposed that a special 1-day anniversary program be scheduled prior to the CEC—ICMC joint meeting in Keystone, Colorado, that would review the advances in cryogenic engineering which had occurred in this distinct but relatively invisible field of engineering during the past 50 years.

Accordingly, a program of 14 papers, covering both the interest of CEC attendees and ICMC attendees, was envisioned to cover the various aspects of cryogenic engineering.

Authors were invited to prepare these review papers, but because of time restrictions the technical program was limited and not all papers were presented orally. As a result, the CEC and ICMC boards recommended that a separate monograph, in addition to the regularly published two volumes of Advances in Cryogenic Engineering, be prepared which would include all of the invited papers.

This monograph is the result of that recommendation. To provide an assessment of the status of cryogenic engineering 50 years ago, a historical summary of cryogenic activity is presented in the first chapter. The purpose is to review the events occurring during the year period prior to as well as to provide a better understanding of the events that took place after With that historical background, the advances in establishing databases for cryogenic fluids and properties of materials, both metallic and nonmetallic, are discussed and their present status evaluated.

The advances in cryogenic fundamentals are then covered, with reviews of cryogenic principles, progress in cryogenic insulation, development of low-loss storage systems for cryogenic fluids, establishment of modern liquefaction processes, modifications occurring in helium cryogenics, and improvements achieved in cryogenic thermometry.

The monograph then reviews several well-established applications resulting from the cryogenic advances noted above. The cryocoolers developed for aerospace missions are many in number and show a steady progress to achieve long-life coolers and cryostats. The actual application of superconductivity is noted in two chapters, one considering low-temperature superconductivity activities and the other considering high-temperature superconductivity activities.

Both are contributing to modern concepts of power transmission and storage, high-power magnets, and v vi Preface sophisticated medical equipment. Cryopreservation of tissues and organs is undergoing considerable change with a better understanding of the effects of cryoprotectants. Obviously, there are other applications that could have been included, but the value of the monograph would have been lost. The preparation of even a monograph requires the assistance of many individuals.

The editors thank the authors for their interest and time required to prepare a review, a process that normally necessitates considerable effort in literature review and evaluation. We also want to thank the many reviewers of the chapters and the constructive comments that were provided.

Finally, we want to recognize the many contributions made by Cynthia Ocken, from the University of Colorado and assistant to one of the editors. Her daily updating of changes made in the chapters over many months and the overall control of the publication process are greatly appreciated and admired.

In practice, these two areas often overlap and the boundary between conventional and cryogenic refrigeration is often indistinct. Significant reductions in temperature often have very pronounced effects on the properties of materials and the behavior of systems.

Many cryogenic applications have developed as the refrigeration techniques prior to have improved, although many applications still face stiff competition from ambient temperature phenomena because of the associated refrigeration problems. This review shows how the development of new applications over the past 50 years is closely tied to the advances in cryogenic refrigeration prior to The ability to harness and apply these temperature effects is a unique feature of mankind, and it has contributed to great advances in our civilization.

Mankind has discovered abundant uses for high temperatures, beginning in prehistoric times with the use of fire for warmth, light, and cooking. Later, but still more than 20 centuries ago, mankind learned to forge tools and make crude pottery using heat from fires. As civilization advanced and higher temperatures could be achieved, stronger metals, such as iron, could be forged into tools, and much stronger pottery and china could be produced by the higher temperature firing sintering of clay.

June D. It is known that normal hydrogen is a mixture of two gases referred to as ortho hydrogen and para hydrogen, and that the equilibrium concentration of ortho hydrogen and para hydrogen varies with temperature. At temperatures above about F. It is also known that ortho hydrogen conversion is an exothermic reaction, releasing about B. The percentage of liquid hydrogen that is lost by vaporization is a function of the ortho hydrogen composition of the liquid hydrogen at the time ortho hydrogen conversion begins, such as the time liquid hydrogen is introduced into a storage vessel, and a function of the degree of completeness of conversion of ortho hydrogen to para hydrogen, that is, the storage period. Thus it is not practicable to store liquefied normal hydrogen. It has been proposed in the past to accelerate conversion of ortho hydrogen to para hydrogen by the use of a catalyst placed in the liquid receiving zone of a hydrogen liquefier in intimate contact with liquefied hydrogen under atmospheric pressure. With this arrangement, it is possible to produce liquid hydrogen of high para concentration which may be stored at atmospheric pressure without appreciable liquid loss. However, there is no saving in power since the power required to produce a given quantity of liquid hydrogen of high para concentration by catalytic conversion at atmospheric pressure is substantially the same as the power required to produce the same quantity of liquid hydrogen of similar para hydrogen concentration when autogenous ortho hydrogen conversion takes place. It is therefore an object of the present invention to atent provide a novel method of and apparatus for producing liquid hydrogen of high para concentration.
