From abstract: "A report on when antifreeze should be installed, what strength should be used, and what kind of antifreeze is best suited to the service involved."
Chart showing bending moment due to wind pressure on poles for various pole heights, circumferences, and loading. It is enlarged from figures in NBS discussion of national electrical safety code (handbook H39).
Chart of catenary curve ordinates: "The curve gives approximate values of sag at all points on the catenary curve expressed in per cent of the center sag. The error is negligible for all spans in which the center sag is less than 10% of the span length." It is enlarged from figures in NBS discussion of national electrical safety code (handbook H39).
Two charts are given for each of the gases hydrogen, nitrogen, and oxygen. The first gives directly the number of standard cubic feet of the gas which a cylinder will deliver. The second chart gives values of the compressibility factor and of the density.
Chart related to conductor loading showing vertical, transverse and conductor loads in pounds per linear feet of conductor. It is enlarged from figures in NBS discussion of national electrical safety code (handbook H39).
Fundamental principles and techniques used for voltage measurements primarily for frequencies in the upper audio- and radio-frequency ranges and including part of the ultrahigh frequency range.
From preface: "This issue of the Manual of Fire-Loss Prevention, the first edition of which was published in 1934, includes revisions and additions made in part to cover improvements in the past 10 years in methods of preventing and controlling fires. Such methods remain dependent largely on the elimination of preventable fires and abatement of loss from those that originate, by the use of appropriate designs and materials in building construction and the installation of applicable fire alarm and extinguishing equipment, to the extent justified by the hazard" (p. ii).
Map of the United States and surrounding areas with time zones marked and labeled in red. Bodies of water are marked, with depth marked by hatchures, as well as state lines and major cities..

Report with two nomograms presented for rapidly obtaining the compound composition of hydrated limes from the oxide analysis. The general nomogram can be applied to any commercial hydrated lime and gives values accurate to within 0.3 percent while the special nomogram is applicable only to regularly hydrated and highly hydrated dolomitic limes and is accurate to within 0.1 percent.
Introduction: The purpose of this circular is (a) to emphasize the seriousness of certain risks to life and property frequently occurring in or about the home, (b) to give simple methods of care and caution against such hazards, and (c) to stimulate interest in public measures directed toward safety for household and community.
Report presenting tables of the confluent hypergeometric function and some related functions. Information regarding the scope of tables, analytical properties, and approximations are provided.
Chart showing the ultimate resisting moments of wood poles based on the circumferences at ground line for different kinds of woods. It is enlarged from figures in NBS discussion of national electrical safety code (handbook H39).
