Abstract

A method and apparatus for isolating and purifying a .sup.213 Bi radioactive isotope from an .sup.225 Ac source using a primary column and a primary sorbent which preferentially retains .sup.225 Ac over .sup.213 Bi when exposed to a compatible solvent in combination with a secondary column having a secondary sorbent which retains .sup.213 Bi when exposed to a mixture of the compatible solvent and .sup.213 Bi. A "compatible solvent" is a solvent which will preferentially remove .sup.213 Bi radioactive isotopes from a primary sorbent without removing .sup.225 Ac radioactive isotopes, and then allow .sup.213 Bi radioactive isotopes removed from the primary sorbent to be retained on a secondary sorbent, without having to dilute or otherwise chemically or physically modify the compatible solvent in between exposure to the primary and secondary sorbents.

Process and apparatus for the production of BI-213 cations

Patent Horwitz, E Philip [Naperville, IL]; Hines, John J [Newark, IL]; Chiarizia, Renato [Elmhurst, IL]; ...

A process for producing substantially impurity-free Bi-213 cations is disclosed. An aqueous acid feed solution containing Ac-225 cations is contacted with an ion exchange medium to bind the Ac-225 cations and form an Ac-225-laden ion exchange medium. The bound Ac-225 incubates on the ion exchange medium to form Bi-213 cations by radioactive decay. The Bi-213 cations are then recovered from the Ac-225-laden ion exchange medium to form a substantially impurity-free aqueous Bi-213 cation acid solution. An apparatus for carrying out this process is also disclosed.

Method and apparatus for improving resolution in spectrometers processing output steps from non-ideal signal sources

Patent Warburton, William K.; Momayezi, Michael

A method and apparatus for processing step-like output signals (primary signals) generated by non-ideal, for example, nominally single-pole ("N-1P ") devices. An exemplary method includes creating a set of secondary signals by directing the primary signal along a plurality of signal paths to a signal summation point, summing the secondary signals reaching the signal summation point after propagating along the signal paths to provide a summed signal, performing a filtering or delaying operation in at least one of said signal paths so that the secondary signals reaching said summing point have a defined time correlation with respect to one another,more » « less

Methods and apparatus for measurement of the resistivity of geological formations from within cased wells in presence of acoustic and magnetic energy sources

Patent Vail, III, William B. (Bothell, WA)

Methods and apparatus are provided for measuring the acoustically modulated electronic properties of geological formations and cement layers adjacent to cased boreholes. Current is passed from an electrode in electrical contact with the interior of the borehole casing to an electrode on the surface of the earth. Voltage measuring electrodes in electrical contact with the interior of the casing measure the voltage at various points thereon. The voltage differences between discrete pairs of the voltage measuring electrodes provide a measurement of the leakage current conducted into formation in the vicinity of those electrodes. Simultaneously subjecting the casing and formation tomore » « less

Method and apparatus for coating a patterned thin film on a substrate from a fluid source with continuous feed capability

Patent Burrows, Paul E [Kennewick, WA]; Sapochak, Linda S [Kennewick, WA]

A method and apparatus for forming patterned coatings of thin film, non-polymerizable compounds on a substrate. A mixture of the non-polymerizable compound and a liquid carrier is pumped into the interior of a heated evaporation box having an internal temperature sufficient to convert substantially all of the non-polymerizable compound and liquid carrier to a gaseous form. The non-polymerizable compound and liquid carrier are then removed from the evaporation box via exit slit in the evaporation box. Adjacent to the exit slit, and maintained in a vacuum, is a first substrate upon which the non-polymerizable compound condenses. The first substrate ismore » « less

Method and apparatus for generating radiation utilizing DC to AC conversion with a conductive front

Patent Dawson, John M [Pacific Palisades, CA]; Mori, Warren B [Hermosa Beach, CA]; Lai, Chih-Hsiang [So. Pasadena, CA]; ...

Method and apparatus for generating radiation of high power, variable duration and broad tunability over several orders of magnitude from a laser-ionized gas-filled capacitor array. The method and apparatus convert a DC electric field pattern into a coherent electromagnetic wave train when a relativistic ionization front passes between the capacitor plates. The frequency and duration of the radiation is controlled by the gas pressure and capacitor spacing.
