Rapid failures of tubing in sour condensate wells have led to an investigation of possible causes of these failures. The presence of hydrogen sulfide points to sulfide stress corrosion cracking as the cause. The effect of untempered martensite was studied as to its bearing on the susceptibility of steel to sulfide str…
In the present paper, studies on the phase diagram and magnetic properties of Fe – Te system are reported. It was found by X-ray and thermal analysis that a number of intermetallic compounds are formed from melt through peritectic reactions, and an eutectoid reaction was seen to occur between two compounds α (ca FeTe…
The self-diffusion of liquid sodium in the temperature range, 98° to 226°, has been studied by the capillary reservoir technique. The data fit the empirical equation, D=1.10×10—3 exp (—2430/RT). The Stokes-Einstein equation gives a good correlation of the self-diffusion and viscosity data. The difference in the self-d…
The frictional adhesion between projectile and target during a ballistic penetration has been measured with a torsion-type Hopkinson bar. The apparatus allows measurement of the torsional adhesion of a spinning projectile during target penetration. By assuming the friction resisting rotation to be equal to that resist…
Tongue-tear tests were made on samples of acetate fabrics, varying certain controlled factors: weave, texture, yarn twist, and yarn structure. An analysis of the resulting experimental data showed certain relationships between these fabric factors and tear strength. A qualitative discussion was made of tearing action—…
The empirically determined values of the parameter Dq, which in transition-metal complexes, measure the influence of the ligands on the metal d-orbitals are interpreted theoretically. A quantitative treatment of ``the magnetic criterion of the bond type,'' is given. Values of Slater-Condon parameters for transition me…
CLOSTRIDIUM OEDEMATIENS n-ANTIGEN 315 3. The viscosity-reducing action is due to a sulphydryl-activated enzyme, which has been named a tropomyosinase, whose action is inhibited by homologous antisera.
It is concluded from torque measurements on single crystals of Alnico 5 that the high coercive force of these crystals depends upon the shape anisotropy of the fine precipitated plates and that the crystal anisotropy of the plates is negligible. The present physical picture of the alloy is that it consists of plates o…
The infrared absorption spectra of fused B 2 O 3 and of a series of soda borate glasses are presented. These spectra were obtained using vacuum‐pressed briquettes of the powdered glass and powdered KBr. The spectrum of fused B 2 O 3 shows quite definitely that this glass does not consist of a completely continuous tri…
The attenuation of ultrasonic waves by conduction electrons is analysed in terms of the free-electron model of a metal. At such low frequencies that the electronic free path is smaller than the wavelength, the result obtained agrees with that found by other authors using simpler concepts, but this agreement breaks dow…
