Thermal Insulation of Single and Multiple Layers of Fabrics

Mary Ann Morris1955-09-01Textile Research Journal

Thermal insulation, thickness, and volume of air per unit area of fabric have been determined for single and multiple layers of fabrics. A comparison of the thermal in sulation and thickness values obtained by the actual measurement of multiple layers of fabrics to those obtained by adding the values of the individual…

Measurement of Susceptibility Tensor in Ferrites

J. O. Artman、P. E. Tannenwald1955-09-01Journal of Applied Physics

Experimental techniques for measuring the magnetic susceptibility tensor components in microwave cavities are described. General expressions for the perturbation of microwave cavities by the magnetic properties of ferrites are developed. Experimental results are given for Ferramic 1331 measured at 9165 Mcps. Since the…

Thermal Decomposition of Nitric Oxide

F. Kaufman、J. R. M. Kelso1955-09-01The Journal of Chemical Physics

The decomposition of pure nitric oxide and of mixtures with nitrogen or helium was studied at T = 1170 to 1530°K in quartz vessels. Above about T = 1400°K, the reaction is homogeneous and cleanly second order in NO throughout the course of decomposition. A change in the surface to volume ratio leaves the rate unchange…

The Curing of Silicone Rubber with Benzoyl Peroxide

A. M. Bueche1955-09-01Rubber Chemistry and Technology

Abstract Little has been reported about the action of benzoyl peroxide as a vulcanizing agent for silicone rubber. Knowledge of this action seems to be of consider- able importance, since benzoyl peroxide is the most widely used vulcanizing agent at the present time. Apparently no studies of the kinetics of peroxide d…

The Wetting of Insect Cuticles by Water

M. W. Holdgate1955-09-01Journal of Experimental Biology

ABSTRACT The water contact angles of insects show a wide range of variation, which is broadly correlated with surface roughness and with habitat. The contact angles of species inhabiting stored products or carrion are greatly modified by contamination. This produces large variations between apparently similar individu…

Determination of crystallinity in polyethylene by X‐ray diffractometer

S. L. Aggarwal、George P. Tilley1955-09-01Journal of Polymer Science

Abstract A convenient and rapid x‐ray diffraction method is described for the determination of per cent crystallinity in polyethylene, using a scanning goniometer with Geiger tube and scaler counter. Results are presented on per cent crystallinities of a number of polyethylenes and on samples made by quenching polyeth…

Fuel economy in brick drying

S.F.S.1955-09-01Materiales de Construccion

Mediante el empleo de dos nuevos mecheros Suxé, junto con la introducción de algunas reformas, se ha conseguido disminuir el consumo de combustible en la operación de secado, evitándose, al mismo tiempo, la presencia de humos.

On the relations between structure and morphology of crystals. II

P. Hartman、W. G. Perdok1955-09-01OpenAlex

The characteristic features of S-faces (stepped faces, i.e. faces parallel to one periodic bond chain only) are further developed. After giving some definitions, a discussion follows of the factors determining the morphological importance of S-faces. The conclusion is drawn that the development of S-faces in a particu…
