A bstract A phase‐equilibrium diagram of the system BaO–B 2 O 3 has been constructed from data obtained essentially by the quenching method. Four congruently melting compounds were identified: BaO·4B 2 O 3 , melting at 879 ± 5°C.; BaO·2B 2 O 3 , melting at 900 · 5°C.; BaO·B 2 O 3 , melting at 1095 ± 5°C.; and 3BaO·B 2…

Many of the methods used to study the fine structure of cellulose are tedious and not suitable for routine use. In the present work, an equilibrium moisture regain method which can be carried out on a large scale with a high degree of accuracy has been developed. The method is illustrated by a wide variety of cellulos…
Abstract This paper contains an approximate three-dimensional solution for the stress distribution around a circular cylindrical hole in an infinite plate of arbitrary thickness, which is otherwise in a uniform state of plane stress parallel to the bounding planes. The approach used rests on a modification of the Ritz…

A thermodynamic analysis of phase equilibria similar to that developed in Part IV when applied to the ternary system of two polymers and a solvent leads to an explanation of the usual incompatibility of different high polymers in solution. Unless their heat of mixing is virtually zero or negative, two high polymers ar…
The expansivity of many glasses can be increased almost 10 percent by increasing the equilibrium temperature fr om 150 to 200 deg C above t he lowest such temperat ure attainable by lo ng annealing treatments in t he lower part of t h e annealing range. By ch an gi ng t he equilibrium temperatures of a number of the b…
