Efficiency of thorium extraction by primary amines as a function of pulse frequency and amplitude in a pulsed sieve-plate column

Creator:: Davis, Bernard Eric, 1937-
Abstract:: The amine extraction process is evaluated for pulse column operation. A 0.1 M solution of Primene JM-T (a commercial mixture of tertiary-alkyl primary amines) in a kerosene-base diluent is the extractant for thorium feed in aqueous acidic sulfate solutions. Equilibrium isotherms at room temperature are presented at aqueous acidities of...

The analytical application of the galvanic dissolution of niobium and tantalum : the determination of nitrogen

Creator:: VanSanten, Richard Theodore
Abstract:: Nitrogen is a contaminant of niobium and tantalum adversely affecting the workability of the metal. With recent interest in the refractory metals, one problem the chemical analyst must solve is the accurate determination of nitrogen in niobium and tantalum at very low levels. The usual method of assaying for nitrogen...

Electronic data processing with specific reference to the preparation, duties, and qualifications of the programmer in the city of Portland, Oregon

Creator:: Backlund, Darien Howard, 1911-
Abstract:: Purpose of Study: The purpose of this study was to find the specific qualifications of a programmer in order that counselors and educators can better advise students who are interested in electronic data processing for career purposes. The information received from the data processing companies will offer some criteria on...

Equilibria in the ion exchange systems H⁺¹-CS⁺¹, H⁺²-Sr⁺², H⁺¹-Ce⁺³, Cs⁺¹-Sr⁺², Sr⁺²-Ce⁺³, H⁺¹-Cs⁺¹-Sr⁺², H⁺¹-Cs⁺¹-Ce⁺³ and H⁺¹-Sr⁺²-Ce⁺³

Creator:: Meyer, Walter
Abstract:: A new method for determining ion exchange equilibrium data by liquid scintillation counting of the equilibrated solution phase is described. This method has been applied to determine equilibria between Dowex 50W X8, a commercial strong cation exchange resin, and binary and ternary solution containing the varying combinations of H⁺¹, Cs⁺¹,...

Design of a continuous countercurrent ion exchange unit, and operating characteristics for the aqueous cupric sulfate-sodium sulfate-Dowex 50W-X8 system

Creator:: Olsen, Richard Standal
Abstract:: A countercurrent, liquid-solids contactor was constructed, operated and evaluated for a continuous ion-exchange operation. The exchange of cupric and sodium ions between aqueous solutions and Dowex 50W-X8 ion exchange resin was studied. The countercurrent contactor consisted of two, three-inch diameter columns with active sections ranging from one to four feet...

Spectral time-resolution of light from microwave discharges in helium

Creator:: Tynes, Arthur Richard
Abstract:: Temporal variations in individual spectrum lines emitted by a microwave discharge in pure helium are investigated: The discharge is produced in a quartz tube located inside of a section of waveguide which carries pulsed 3 centimeter microwaves. The helium used is purified by a three-fold process consisting of treatment with...

A model of ciliary streaming in the respiratory system

Creator:: Chambers, Alan B.
Abstract:: The respiratory tract is lined with a mucous blanket which is motivated by a ciliated epithelium. This blanket includes a lower serous layer of fluid through which the cilia beat and an upper viscid layer into which particulates from the inhaled air are deposited. The movement of the mucous blanket...

Effectiveness of a fluidized bed in filtration of airborne particulate of submicron size

Creator:: Black, Charles Hartgraves
Abstract:: Submicron particulate (mean size of 0.52 microns) was filtered from air at substantially atmospheric temperature and pressure by passing air up through a bed of fluidized glass shot in a two inch column. Removal efficiency, defined as the percentage removal of particulate from the air stream, was essentially constant during...

An investigation of the removal of ozone by activated charcoal

Creator:: Liffick, Glenn Lonngren
Abstract:: The removal of ozone from an air stream by activated-cocoanut charcoal was investigated from the literature and experimentally. The experimental investigation showed that activated-cocoanut charcoal can be used to remove concentrations of ozone less than 1.0 ppm with high efficiencies. The mechanism of the ozone removal appeared to be a...
