The re-examination of the crystal structure of α-hexagonal BaAl2Si2O8 has revealed that the true symmetry of the crystal is lower than hexagonal-possibly, orthorhombic with a body centered lattice of dimensions: a=5.293, b=9.168 and c=7.79×2Å, and the crystals invariably occur in a trilling form made up by three ortho…

The surface tension of a commercial soda‐lime‐silica glass was measured in various atmospheres in the temperature range 500° to 700° C. The method of fiber elongation was used and its usefulness is illustrated. Water vapor was found to exhibit the most pronounced effect, causing a lowering from 315 to 205 dynes cm. −1…
Phase relationships in the system Li 2 O, B 2 O 3 ‐B 2 O 3 were studied by the quenching method using twenty compositions. The crystalline phases encountered were ( a ) Li 2 O, B 2 O 3 , which melts congruently at 849°± 2°C., ( b ) Li 2 O.‐2B 2 O 3 , which melts congruently at 917°± 2°C., ( c ) a new compound, 2Li 2 O…
All passivating‐type inhibitors are oxidizing agents. However, not all oxidizing agents are inhibitors. A passivating ‐type inhibitor functions by producing local‐action current which anodically polarizes a metal into the passive potential region and thereby provides the means for obtaining a noble mixed potential. Th…
In einem Cosseratschen Kontinuum ist jedem Punkt einer stetigen Punktmenge eine räumliche Orientierung zugeordnet. Es werden die kinematischen und statischen Gleichungen eines solchen Kontinuums aufgestellt und die Analogien zwischen diesen Gleichungssystemen besprochen. Es wird gezeigt, daß das kinematische Modell de…

Low- and high-temperature x-ray diffraction investigations of titanium dihydride (TiH/sub 1.99/) and dideuteride (TiD/sub 1.98/) have indicated apparent 'second-order transformations' in both substances below a critical temperature of 310 deg K. The tetragonal low-temperature phases are distortions of the cubic fluori…

Abstract Les grandes différences dans le cours du dégagement électrolytique de l'hydrogène sur les différents métaux doivent provenir principalement de différences dans l'état de la liaison des atomes H chimisorbés, qui apparaissent comme produit intermédiaire dans ces réactions. On en déduit que le ralentissement des…

An attempt is made to analyze the factors which determine the operation of the bubble chamber. It is concluded that the majority of bubbles in conventional chambers are nucleated by moderately energetic free electrons produced by the incident particles in Coulomb encounters. Nuclei are displaced too infrequently by Co…
