We are detached by 130 years from the significant experiences of Cailletet and Pictet which results were discussed on December, 24, 1877 at session of the French Academy of Sciences. To these researchers on created by them original as presentation of that time plants it was possible to come nearer to temperature of liquefaction of oxygen — one of four so-called constant gases. Achievements of these researchers deserve a high estimation as they have made breach in area of cryogenic temperatures. In this connection the 1877 is considered a year of birth of cryogenic technology. The features used by these researchers in plants of processes, technologies and designs are analyzed in article. The executed estimations are confirmed with an opportunity of liquefaction of oxygen with the help of the plants created for this purpose.
