From abstract: Drillhole DOE-2 was drilled to investigate a structural depression marked by the downward displacement of stratigraphic markers in the Salado Formation ~ 2 mi north of the center of the WIPP site. This depression was named informally after the shallow borehole FC-92 in which the structure was described. The presence of the depression was confirmed by drilling.

From abstract: This report is a technical and economic evaluation of five representative cell laydown techniques with the final goal being a determination of which was most promising from a cost performance basis.

Introduction: Confidence limits as a mathematical tool are applicable to many development engineering and production engineering situations. In order to make confidence limits readily available to engineers, a computer was designed which will approximate certain confidence limits.

From abstract: Crater dimensions have been determined for 23 explosions of 256-pound spherical TNT charges buried in desert alluvium. As opposed to previous work covering depths of burst as great as 6 feet, the work presented in this report extends knowledge of apparent crater radius and depth to depths of burst as great as 30 feet.

Abstract: "Spherical charges of TNT, each weighing 256 pounds, were exploded at various depths in tuff to determine apparent crater dimensions in a soft rock. No craters were obtained for depths of burst equal to or greater than 13.3 feet. It was deduced that rock fragments were sufficiently large that charges of greater magnitude should be employed for crater experiments intended as models of nuclear explosions."

A quantizing pulse ammeter has been designed which brackets an input pulse current peak between two preset current levels. These levels are easily selected by calibration circuits contained on the chassis. Readout is presented in the form of a Nixie visual display as well as an output which is suitable for automatic data recording.

The following report describes the design and intended function of the tolerance comparator device, a tool designed to aid those engaged in the manufacture and inspection of parts as defined by drawings using positional tolerances.

The following report describes the purpose and usage of the tolerance comparator, and Sandia Corporation's investigation of the drafting practice leading to the aid.

This report presents a description of and operating instructions for APOTA--a device which automatically tracks any signal-emitting source within the 190 to 250 MC band. APOTA is especially useful for telemetering applications.

From abstract: This report includes results of studies of crater dimension, throwout material distribution, ground motion, dust cloud growth, and long-range air blast.

Abstract: "The pressure drop and the time-temperature variation of the air test medium and heat storage material in a pebble-bed heater (designed for intermittent hypersonic wind-tunnel operation at test section Mach numbers of 4 to 11) are presented."

Abstract: "The pressure drop associated with the flow of air through a cylindrical bed of spherical pebbles has been investigated experimentally. The results of this investigation are reported here."

From abstract: Many residents of the Nevada area carried film badge radiation dosimeters during Operation Plumbbob in 1957. Badge readings in specific localities appear to follow the logarithmic-normal distribution.

Abstract: "Available data on wind persistence and wind forecasting capability have been applied in estimating the probability of a fallout pattern shifting from an uninhabited safe sector into a populated region. Safety probability is computed from win variability, forecasting accuracy, initial height and particle size of radioactivity landing at a point in the predicted fallout pattern, predicted wind speed, length of forecast period, and safe-sector angular width."

Abstract: "Wind observations collected at Yucca Flat since 1951 are analyzed for timewise variability. Variability functions of altitude, season, wind speed, and vector wind are described. Derived variability parameters are incorporated into calculations of fallout safety probability for NTS operations."

Abstract: "Presented in this report is a numerical method by which may be calculated the amplitudes of the trains of pulses that result when a single simple stress pulse encounters a zone of many abrupt discontinuities in a slender rod. The notational scheme employed enables the system of multitudes of individual progagating waves to be studied in terms of analogous number sets which may be mechanically generated. The notational concept and related operational rules, described in this report, have been used to program the problem for solution with the IBM 704 computer. The program is briefly discussed. Illustrative examples were computed for rods of two to ten discontinuities. These were compared with a pulse reflected in a rod of an unlimited number of steps."

The short-circuit coaxial antenna in a lossy medium is analyzed using transmission line theory.

Specimens of two ferroelectric materials, barium titanate and lead-zirconate titanate, have been subjected to high dynamic stresses by impacting them with a projectile accelerated by an air gun. The purpose of these tests was to supplement information previously obtained using high explosives to stress the ferromagnetic materials.

Abstract: The APAR-3G system is an automatic programming, controlling and recording machine which is readily adaptable to a wide variety of automated data acquisition and constrol system applications. It is physically and logically modular to permit the assemby of minimum or maximum capability machines. This system can perform the necessary acquisition and control in a typical factory environment and can generate an output (for data reduction) which is compatible with available computer systems.

From abstract: The PT-750 is designed to be used in conjunction with a production tester which requires automatic recording of test data. This manual provides a source of procedures and reference material necessary in automatic recording and in use of the PT-750.

Abstract: This memorandum discusses a new design definition technique, requiring no standard, which pictorially shows part and gage limits on the same drawing. When functional gages, test fixtures, or optical chart gages are the selected inspection method, design, manufacturing process, and gage engineers can use these drawings directly to replace the usual standards-based drawings. In essence, this advanced technology visually describes true position dimensioning and tolerancing. It enables product designers to directly control the acceptance process.

Abstract: Bechtel National, Inc. has conducted a study of the requirement for, and a preliminary design of, a photovoltaic central station test facility.

Abstract: This document outlines the essentials of the planning and action necessary for the recovery of radioactive contaminated equipment following a radiological disaster. It lists the records which should be collected before a disaster and discusses the training of personnel for recovery teams. Radiation doses, radiation indicators, and protective clothing are all treated in a general fashion. Procedures are given for the actual recovery of equipment, with emphasis on personnel safety. Decontamination techniques and materials are then discussed. Graphs and simple calculations are presented for determining safe work limits and radiation doses under varied conditions. A list of typical sources for radiological supplies and a brief bibliography are also included.
