Performance Characteristics of Synthetic Fibers, Wool, Viscose, and Blended Fibers in Axminster Carpets
The soiling and crushing characteristics of nylon, Dacron, 2 Orlon, 3 Saran, Dynel, acetate, wool, and smooth viscose, as well as the 50/50 blends of the synthetics and wool with smooth viscose were studied in Axminster carpets. Soiling properties are shown to be related to the fiber surface smoothness and avail able…
Rate of nitration of benzene with mixed acid
Abstract The rates of nitration of benzene by nitric acid in mixed acid to produce mononitrobenzene have been measured in well‐emulsified reaction mixtures in the temperature range from 34° to 54°C. The acid‐phase compositions ranged from 1.6 mole % nitric acid and 27 mole % sulfuric acid to 35 mole % nitric acid and…
Topsy, A Remotely Controlled Critical Assembly Machine
A remotely operated facility for the study of reacting metal assemblies with thick reflectors is described. Design of the assembly machine permits adaptation to nuclear components of various materials and geometries. Data resulting from experimental programs on the behavior of reflected critical assemblies can be appl…

The Measurement of Tearing Strength of Textile Fabrics
Current versions of two methods commonly used for the determination of tearing strength require clarification regarding treatment of the data obtained and revision to accommodate newer types of inertialess testing machines. Experimental information, providing the necessary background data, has been obtained. Sixteen f…

Cotton Quality and Fiber Properties
The purpose of this research was to evaluate the use of single-fiber testing methods for the determination of cotton fiber properties and for the prediction of yarn quality. Samples of unprocessed cotton, finisher drawing sliver, and 36's carded yarn were ob tained for 21 domestic cotton varieties representing extreme…
The copolymerisation of methyl methacrylate and maleic anhydride
Abstract The kinetics of the copolymerisation of methylmethacrylate and maleic anhydride have been examined at 60°C. The reactivity ratios have been determined by analytical and radioactive techniques and are r 1 = 3.5 and r 2 = 0.03. Radioactive azoisobutyronitrile has been used as initiator; the rate and efficiency…
Oxide Films on Stainless Steels
Oxide films on stainless steels have been classified into three types according to film thickness, film structure, film composition, and influence of the film on resistance to corrosion. Compositional properties of oxide films isolated from surfaces of stainless steels were studied using specially developed microanaly…

Electrical and Optical Properties of a Semiconducting Diamond
The electrical resistivity and Hall coefficient of a semiconducting diamond (Type IIb) have been measured between - 100°C and 600°C using standard d.c. methods. The diamond behaves like a normal p-type semiconductor. At 20°C its resistivity is 270 ohm cm and the Hall mobility of the holes is 1550±150 cm 2 volt -1 sec…
Crystal‐size distribution in mixed suspensions
Abstract Although vacuum crystallizers are used widely, crystal‐size–control methods have not been adequately analyzed. This paper supplies in part the deficiency of technical information on this problem. Industrial crystallizers may have inherent nucleation rates in excess of or below the seed‐crystal requirement for…

Ionization of radioactive particles in the free air
In order to evaluate the possible role of radioactive particles from an atomic cloud as condensation nuclei, an analysis has been made to determine their degree of ionization. Individual radioactive particles become ionized due to β emission, and an estimate of the half-life of these ions has been made for various tim…
