The flow of air through compact bundles of parallel textile fibers has been studied in order to obtain values of the shape factor k0 for the channels through which the flow takes place. When the fibers are cylinders and the flow is parallel to their axes, k0 is an increasing function of the porosity ε. Tables and curv…

The rate of mechanical deterioration of cellulose insulation is dependent on the conditions of its use. Those factors of major importance are the temperature applied and the presence of oxygen and moisture. Moisture even in small amounts greatly affects the mechanical stability of the cellulose insulation. In general,…

Part I . After a brief statement of the present unsatisfactory position regarding the life history of Polystomella crispa , an account is given of experiments with various fixatives on P. crispa , collected near Drake's Island, Plymouth. A method is described for the cultivation of Polystomella in diatom cultures, esp…
Nickel‐tungsten alloys have been electrodeposited from the Watts type nickel plating bath which was modified by the addition of small amounts of sodium tungstate. Alloy composition and current efficiencies were studied at various cathode current densities, bath pH's and bath temperatures. Many of the cathode deposits…

Abstract A new structure of carbon is proposed in order to account for the occurrence of extra lines on X-ray powder photographs of graphite. It has hexagonal layers similar to those of graphite, but arranged in a different sequence. About 14 % of the new structure is present in the samples examined.

Results are given which indicate that the ability of a textile fabric to withstand repeated flexing depends upon the struct ure of the fabric, the position and structure of the yarn in the fabric, and t h e kind of fib er from which the fabric is made.
For high accuracy in commercial refractometry, refractometers should be used more strictly as comparison instruments and series of standard samples with known refractivities over a range of room temperatures should be available for frequent check measurements. Tests for various mechanical and optical defects are neces…
