Theoretical Interpretation of Field Emission Experiments
In careful experiments by Dyke and his co-workers it has been observed that the field-emission currents from tungsten and barium-on-tungsten emitters were progressively reduced below that expected from the Fowler-Nordheim law as the field was increased. These effects were attributed to electron space charges in the ne…
Reflection-Reducing Coatings of Magnesium Fluoride and Lithium Fluoride in the Near Infrared
A brief derivation of formulas for the transmittance of flat plates, uncoated and coated, is presented. Data showing the increased near infrared transmittance of seven flat samples resulting from quarter-wave coatings of MgF2 and LiF on their surfaces is presented. Five were coated to maximize transmittance for a wave…

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…
