Abstract Single-crystal test specimens of van Arkel titanium were obtained by a modification of the strain anneal technique.The modes of slip have been identified as (101̄0) [112̄0],(101̄1) [112̄0], and (0001) [112̄0]. It has been shown that not only does the interstitial impurity affect the magnitude of the critical…
Fabric dust collectors are used industrially for the separation of dusts and fumes from air and gases in many manufacturing and material handling processes.As a class, these collectors are generally greater than 99% efficient by weight on dusts ranging from SO microns to the submicron sizes, when inlet dust loadings e…

Ultrasonic absorption coefficients (at about 8 Mc/sec) were determined by the pulse technique in glycols, cyclohexanol and m -cresol in dependence of the temperature. Also the ultrasonic velocity (at 1.43 Mc/sec) in these liquids was determined by the ultrasonic interferometry. The experimental absorption coefficient…
Abstract Die Darstellung von reinstem K 2 MnO 4 wird beschrieben. Die thermische Zersetzung von K 2 MnO 4 im O 2 ‐ und N 2 ‐Strom im Temperaturbereich 500° bis 900° wird untersucht. Durch quantitative Aufarbeitung des Reaktionsproduktes wird gezeigt, daß diese Zersetzung im Prinzip stets nach der Gl. (3) K 2 MnO 4 = 2…

The Raman spectra of crystalline NH3 and ND3 were measured at —82°C, using Hg 2536.5A exciting radiation. The fundamentals v1, v2, and v3 were observed, but v4 was not. v2 was split into two components by intermolecular coupling. Lattice frequencies of both translational and rotational origin were observed, and there…
Results of an investigation of some properties of the systems CaO‐B 2 O 3 , SrO‐B 2 O 3 , and BaO‐B 2 O 3 are reported. The formation of two liquids at low RO concentrations limited the range of compositions which could be measured. The values of surface tension and temperature coefficient of surface tension obtained…

Measurements of resistivity, Hall coefficient, and optical absorption of AlSb are reported. The width of the forbidden energy band, derived from electrical and optical data, is 1.6 ev at absolute zero. Absorption bands are observed at 0.75 ev in $p$-type samples and at 0.31 ev in tellurium-doped $n$-type specimens. An…
On the basis of a simplified model an explanation for the high-frequency limit of ultrasonic cavitation is suggested and compared with published experimental data.
The near infra-red region may be used to obtain spectra with polarized radiation of natural and synthetic fibres. This region has considerable experimental advantages and the spectra of poly-L-alanine, polyglycine, wool, silks and commercial regenerated protein fibres are shown and discussed. Besides supplementing oth…
An interferometer of the amplitude-splitting type has been constructed which operates with electron beams and produces a system of fringes in the viewing instrument. The appearance of the fringes may be varied at will by introducing changes in one of the (electron) optical paths. The instrument utilizes crystalline di…
