Accidents from explosives at metal and nonmetallic mines

Description: Circular produced by the U.S. Bureau of Mines to promote safety through a series of reports on accident prevention in mines. According the the scope statement, "This is the fourth section of the revised series of circulars that cover various phases of accident prevention in metal and nonmetallic mines; it give information on accidents and injuries from storing, handling, and using explosive in metal and nonmetallic mines and discusses the precautions by which they can be prevented" (p. 2).

Aerodynamic Characteristics of a 0.04956-Scale Model of the Convair TF-102A Airplane at Transonic Speeds, Coord. No. AF-120

Description: "The basic aerodynamic characteristics of a 0.04956-scale model of the Convair TF-102A airplane with controls undeflected have been determined at Mach numbers from 0.60 to 1.135 for angles of attack up to approximately 22 deg in the Langley 8-foot transonic tunnel. In addition, comparisons have been made with data obtained from a previous investigation of a 0.04956-scale model of the Convair F-102A airplane. The results indicated the TF-102A airplane was longitudinally stable for all conditions tested" (p. 1).

Aerodynamic Characteristics of a Circular Cylinder at Mach Number 6.86 and Angles of Attack Up to 90 Degrees

Description: "Pressure-distribution and force tests of a circular cylinder have been made in the Langley 11-inch hypersonic tunnel at a Mach number of 6.88, a Reynolds number of 129,000, and angles of attack up to 90 degrees. The results are compared with the hypersonic approximation of Grimminger, Williams, and Young and a simple modification of the Newtonian flow theory. An evaluation of the crossflow theory is made through comparison of present results with available crossflow Mach number drag coefficients" (p. 1).

Aerodynamic interference of slender wing-tail combinations

Description: From Introduction: "In the present paper, the emphasis is placed on calculating the variations of total forces and moments with angles of attack and sideslip for a number of slender plane and cruciform wing-tail combinations and for some airplane-type arrangements of a plane wing and a horizontal and vertical tail."

Alpha Ferric Oxide: Low Temperature Heat Capacity and Thermodynamic Functions

Description: ABS>The heat capacity of synthetic alpha ferric oxide was determined at 5 to 350 K. The experimental technique is described, and the heat capacity and molal thermodyamic functions are tabulated. The heat capacity vs. temperature is shown graphically. (J.R.D.)

ANALYSIS OF PROMPT EXCURSIONS IN SIMPLE SYSTEMS

Description: A calculation, coded for a fast computer, is discussed that can fairly accurately match the experimental resuIts obtained from the LASL Lady Godiva prompt burst program. In particular, the code can predict the reactivity where the burst yield deviates from a linear dependence on reactivity and commences to rise much more rapidly. The burst width and maximum rates can be predictcd with reasonable accuracy. The calculation is applied to other simple systems, with the result that there appear to be general rules that one can use to relate the bursts of thcse systems. The calculation can predict what fraction of the energy of the system is converted into kinetic energy. It appears that step-function increases of reactivity of about 1O cents or less in homogeneous metal systems develop only a trivial explosive energy. The method was extended to hypothetical accidents in very idealized reactors. Two general models of reactor cores were considered. These are (1) a core of low density in which the characteristic o a threshold is important, and (2) a model in which the spherical shells are alternately normal density and void. The numbers quoted should be regarded only as establishing upper and lower limits. (auth)

An Analysis of William Walton's Concerto for Violin and Orchestra

Description: The rhythmic analyses (derived from the rhythm tables of Chapter II) reveal: 1. Walton used rhythms sparingly. 2. Walton's rhythms constitute an evolutionary state of re-creation, i. e., Walton's rhythms are in empathy with each other. The harmonic analyses (derived from the harmonic fluctuation tables of Chapter II) reveal: 1. The most frequent chords of any classification occur in groups III and IV (chords of the highest tension). 2. The most frequent dissonant interval used is that of the major seventh.

Analytical investigation of the effect of water injection on supersonic turbojet-engine - inlet matching and thrust augmentation

Description: From Introduction: "In order to provide engine-inlet matching to prevent such mass flow spillage and the attendant drags, much mechanical complication has been introduced. References 1 and 2 propose employing this principle at subsonic and supersonic speeds to achieve thrust augmentation. The merits of the system for supersonic engine-inlet airflow matching, as well as thrust augmentation, appear considerable; and a comparative study with existing fixed- and variable-geometry inlets was therefore undertaken."

An Analytical Study of Basketball Goal Shooting in Fifteen Girls' Commercial Basketball Games of the Major City and Industrial Leagues of Fort Worth, Texas, during the Season of 1951-1952

Description: The investigator became interested in the status of basketball goal shooting in modern girls' basketball as compared to that of boys' goal shooting. Types of shots, their frequency and accuracy, and the zones on the court from which they were taken, were all considered as components of the status of basketball goal shooting. It was on the basis of this interest that the present study was undertaken.

[Arthur Godfrey and Gene Hall on The Talent Scout Show]

Description: Photographs of Arthur Godfrey and Gene Hall sitting together during NBC's "The Talent Scout Show" that have been attached to a sheet of white paper. The first five photos features the two middle aged men in dark suits, with Godfrey sitting to the left of the bespectacled Hall. Curtains are visible behind the two. A desk microphone sits between them. On the second page, below the two photos of Hall and Godfrey, there is a photo composed of four pictures. The the top two feature Godfrey and Hall again, while the bottom two feature George Mosse playing a clarinet (left) and George Mosse, Gene Murray playing a trumpet, and Phil Elliot playing a trombone. These three men are wearing striped black and white shirts.

Arthur Godfrey Show - 1957

Description: Photographs of George Mosse (clarinet), Gene Murray (trumpet), and Phil Elliot (trombone) performing on the Arthur Godfrey Show while wearing striped shirts. The top left and bottom right photos show the three men playing together in front of a piano. The top right photo features Murray alone playing the clarinet. The photo on the bottom left contains four images. The top two images on this split photo show Arthur Godfrey (left) and Gene Hall (right) speaking together at a desk with a small microphone between them. The two photos underneath show two more images of Mosse, Murray, and Elliot performing together.
