An Experimental Study of Phase Variations in Line-of-Sight Microwave Transmissions (open access)

An Experimental Study of Phase Variations in Line-of-Sight Microwave Transmissions

From Introduction: "The purpose of this report is to present an analysis of time variations in: (1) the phase (relative to a stable phase reference) if a 9414 Mc/s signal transmitted over this path, referred to hereafter as single-path phase data; (2) the phase observed at one receiving antenna relative to that observed at an adjacent antenna, referred to as phase difference data; (3) atmospheric refractivity as recorded by a microwave refractometer located at the Haleakala terminal; (4) the wind velocity at both ends of the path, and (5) surface atmospheric refractivity measured at 5 stations located on or near the path."

Bibliography and Index on Vacuum and Low Pressure Measurement (open access)

Bibliography and Index on Vacuum and Low Pressure Measurement

From Introduction: "This paper consists essentially of a) a bibliography, b) an author index, and c) an index of the subject matter of the bibliography. While the primary objective is to focus on vacuum measurement, it was believed essential to include in the bibliography articles on vacuum technology in some measure accessory or essential to vacuum measurement. For maximum usefulness, an index of the subject matter of the references has been prepared. The abstract publications listed in the previous paragraph have been freely drawn upon in preparing the bibliography."

Heat Treatment and Properties of Iron and Steel (open access)

Heat Treatment and Properties of Iron and Steel

From Abstract: "This Monograph is a revision of the previous NBS Monograph 18. Its purpose is to provide an understanding of the heat treatment of iron and steels, principally to those unacquainted with this subject. The basic principles involved in the heat treatment of these materials are presented in simple form." From Introduction: "This Monograph has been prepared to answer such inquires and to give in simplified form a working knowledge of the basic theoretical and practical principles involved in the heat treatment of iron and steel."
