Abstract

Prin ciples of ins ul atin g vesse l s for t he storage and t ransp or tation of liqu eli ed gases a re d iscussed. The use of s hi elds cooled by t he vap o r leaving t he liquid being sto red is anal yzed , a nd formulas, gr a phs, a nd t a bles are prese nted for t h e conven ience of t h e d esign er of large vessels fo r storin g and t ranspo rting liquid hy drogen and liquid h elium. A n a nalysis is gi ven of t he use of escapin g vapor t o in tercep t h eat en te rin g by condu ction t hro ugh solid s upport ing m embers.
