The manufacture of synthetic rubber involves several chemical compounds which are toxic to man. A summary of the health hazards involved in the manufacturing process is warranted, as great quantities of synthetic material are being made. This paper deals with experiences encountered in the manufacture of certain types…

Abstract NaBiS 2 and KBiS 2 both have the NaCl structure with Bi 3+ and Na + (resp. K + ) in averaged structure. The cell dimensions are 5.76 Å for NaBiS 2 and 6.01 Å for KBiS 2 . The ionic radius of Bi 3+ is discussed.
The solubility of silica glass in water has been determined through the temperature range 200 degrees C. to 420 degrees C. at a pressure of 300 atmospheres. Some previous investigations of solubility of silica in water, it is believed, have indicated a too great solubility as a result of failure to distinguish true so…
Abstract After some remarks on the importance of phenol formaldehyde resins as vulcanizing agents for rubber, the introductory investigations which led to the methylene quinone theory of the vulcanization are described. Finally this theory is illustrated with the compound 2.6‐di‐bromomethyl‐4‐methylphenol as an exampl…
Abstract Referring to the preceding article describing the methylene quinone theory of the vulcanization of rubber with phenol formaldehyde derivatives, in this paper the arguments in favour of that theory are considered in detail. The results of the investigations in question can be summarized as follows. The vulcani…

The influence of two extreme types of lattice distortions on the X‐ray diagram is demonstrated with the help of a simple one‐dimensional model. In the first type the displacements of the lattice points from their original positions are mutually independent, while in the second type of distortion a similar independence…

An experiment has been designed to check a previously proposed equivalence of the effects of changes in strain rate and in temperature upon the stress-strain relation in metals. It is found that this equivalence is valid for the typical steels investigated. The behavior of these steels at very high rates of deformatio…

(1) At high temperatures (above 80°C) the specific volume of polystyrene is an explicit function of the temperature. dV/dT=0.00043. (2) At low temperatures (below 40°C) the specific volume of polystyrene depends upon its past thermal history dV/dT=0.00024, although V is not explicitly fixed by the temperature alone. (…
