Abstract This paper reports on quantitative measurements of the small angle scattering of various rayons and ramie fibers as functions of moisture content using a three slit vacuum camera and monochromatic radiation. The scattered intensity was normalized on sample thickness and primary intensity through determination…

Structural studies on (Ba-Pb)(Ti-Zr)O 3 system were performed, and the phase diagram of the whole system was determined. In the vicinity of BaTiO 3 , low temperature phases are brought to room temperature by adding Pb and Zr. Substituting some amount of Pb by Ba in Pb(Ti-Zr)O 3 , Curie point becomes lower, but the mor…
Single crystals of isotactic poly-4-methyl pentene-1 were prepared from solution. The crystals were mostly flat squares with more or leas regular shapes. They consisted of thin square layers forming spiral terraces centred on screw dislocations. The molecules were found to be perpendicular to these layers. The same po…
In commercial practice, where temperatures are low, a number of commercially available materials are satisfactory as a container for molten aluminum. None of these, however, resists attack by aluminum in the temperature range 1800° to 2000°C. An investigation was conducted to find a material completely inert to alumin…

Fourteen selected metal ions were added to magnesium basic carbonate, and the MgO obtained after calcining was fired at various temperatures to determine the effect of the additives on the sintering behavior. The magnesia without additives showed rapid increase in density with firing temperature near 1200° C. The majo…
The carbon atom positions in uranium carbides have been determined from neutron diffraction data. UC is face-centered cubic with sodium chloride structure. U/sub 2C/sub 3/ is body-centered cubic with space group 14 bar 3d, and carbon atoms have one parameter of 0.295 with carboncarbon bond distance of 1.295 A. UC/sub…

The conditions influencing the onset of acoustically-induced cavitation in tap water have been investigated, with special attention to the effect of air-filled cavitation nuclei. Cavitation was induced by exciting an acoustic radial mode in the water in a spherical resonator at a frequency near 25 kc/sec. Air-filled n…
A series of detailed measurements have been made of the absorption spectrum of pure vacuum grown crystals of silicon in the wavelength range 2 μ to 30 μ, and over the temperature range 20°k to 365°k. Some new absorption bands have been found, and an explanation is offered for the positions and temperature dependence o…
Abstract Many articles have been written attempting to explain the degradation processes which take place when polyvinyl chloride is aged. Everyone agrees that hydrogen chloride is evolved, color develops, and the polymer eventually becomes stiff and insoluble as a result of crosslinking. Early workers believed that h…

Velocities of individual dislocations have been measured in LiF, covering a range of twelve orders of magnitude in velocity, from 10−7 cm/sec to 105 cm/sec. The velocity is extremely sensitive to applied stress at low velocities, and for each crystal there exists a minimum stress for dislocation motion, below which di…
An ultrasonic vibrational mode with rather well-defined properties has been set up in a cylindrical single crystal of sodium chloride. The saturation of the spin levels of ${\mathrm{Na}}^{23}$ and ${\mathrm{Cl}}^{35}$ by acoustically induced quadrupole transitions, $\ensuremath{\Delta}m=\ifmmode\pm\else\textpm\fi{}2$,…
