The U.S. Bureau of Mines (USBM) was the primary United States Government agency conducting scientific research and disseminating information on the extraction, processing, use, and conservation of mineral resources.
Founded on May 16, 1910, through the Organic Act (Public Law 179), USBM's missions ...
The effect produced by polarization of an anode in the electrolysis of fused salts. It is characterized by a sudden increase in voltage and a corresponding decrease in amperage due to the anode being virtually separated from the electrolyte by a gas film.
Industry:Mining
The effect produced by the chain joint centers being forced to follow arcs instead of chords of a sprocket pitch circle.
Industry:Mining
The effective density at which a separation has taken place, calculated from a specificgravity analysis of the products; commonly expressed as either partition density or equal errors cut point (density).
Industry:Mining
The effective diameter of the piston or hammer, its weight, distance of travel, and the air pressure during the forward movement. The energy of the blow in foot-pounds is equal to: 1/2 mv<sub>2</sub>= w X v<sub>2</sub>/ 64.4, where m = the mass; w = the weight in pounds; v = the velocity of the hammer in feet per second.
Industry:Mining
The effectiveness of a force that tends to rotate a body; the product of the force and the perpendicular distance from its line of action to its axis.
Industry:Mining
The efficiency assigned by the maker under certain specified conditions.
Industry:Mining
The effort necessary to maintain the normal operating speed of a conveyor under a rated capacity load. To this must be added the effort of acceleration, drive losses, etc., to arrive at a final driving effort. Horsepower pull may be referred to in terms such as effective tension, chain pull, turning effort, gear tooth pressure, etc.
Industry:Mining
The ejection of balled drill cuttings from the collar in long, tubelike masses.
Industry:Mining
The elastic axis of a beam is the line, lengthwise of the beam, along which transverse loads must be applied in order to produce bending only, with no torsion of the beam at any section. Strictly speaking, no such line exists except for a few conditions of loading. Usually the elastic axis is assumed to be the line that passes through the elastic center of every section. The term is most often used with reference to an airplane wing of either the shell or multiple-spar type. Compare: torsional center; flexural center; elastic center.
Industry:Mining
The elastic center of a given section of a beam is that point in the plane of the section lying midway between the flexural center and center of twist of that section. The three points may be identical and are usually assumed to be so. Compare: flexural center; torsional center; elastic axis.
