Abstract: The oxidation of uranium is catalyzed with water-soluble copper or zinc chelates. An aqueous solution is prepared containing carbonate or bicarbonate ion, an oxidizer such as hydrogen peroxide or oxygen, and a water-soluble copper or zinc chelate which has at least two amino, carboxylic acid, or thiocarboxylic acid donor groups. The solution is pumped into an underground deposit of uranium. The water-soluble +4 state uranium is oxidized to the water-soluble +6 state which forms a complex with the carbonate ion. The solution is pumped to the surface and is recycled after precipitation of the uranium.

Abstract: Stereo-regular polymers are produced by forming a moving stream of gaseous monomer having an electric dipole moment, irradiating the monomer with monochromatic light of a wavelength suitable for activating it, and orientating the activated monomer in an electric field. The activated, orientated monomer then polymerizes to form a stereo-regular polymer.Alternatively, a monomer of the general formula ##STR1## can be used, where at least one of the R groups, the resonating R group, forms an electric dipole moment with the remainder of the monomer. The monomer is then irradiated with a monochromatic light beam having a frequency which resonates with a harmonic frequency resulting from the bond between the resonating R group and the remainder of the monomer. Activation of that particular bond on that particular type of monomer results in a stereo-regular polymer.For best results, however, the two methods are combined.

Abstract: Alpha particles emitted from radon 220, a daughter product formed from the decay of thorium, are prevented from reaching an alpha particle detector by enclosing the detector in a volume into which alpha-emitting radioactive gases can only enter through a semipermeable membrane at least about 10 mg/cm.sup.2 in thickness. The enclosed volume must be between 30 and 2000 cm.sup.3 and the (AP)/(VL) ratio must be between 10.sup.-7 and 10.sup.-5. Also, the detector must be positioned so as to expose it to gas from the membrane for a distance of at least 2 cm through a solid angle of at least one steradian.

Abstract: A composition is disclosed of a solution of a resinous carrier and at least two compounds which thermoparticulate at different temperatures between 60.degree. and 200.degree. C. A coating is made by applying the composition to a portion of an electrical apparatus exposed to a gas stream. As the temperature of the coating increases the compounds therein thermoparticulate. The time between which the compounds thermoparticulate indicates the rate of rise of the temperature and analysis of the products of thermoparticulation indicates the location of the coating in the electrical apparatus. Alternatively, the coating can consist of several layers with a thermoparticulating compound in each layer which thermoparticulates at different temperatures.

Abstract: Water is decomposed into hydrogen and oxygen in a series of steps. In the first step hydrogen sulfide is reacted with cuprous sulfide to produce the hydrogen and cuprous sulfide. The cupric sulfide is then decomposed to produce sulfur and to regenerate the cupric sulfide. The sulfur is reacted with water to produce the hydrogen sulfide and sulfur dioxide. The sulfur dioxide is reacted with water to produce sulfuric acid. The sulfuric acid is decomposed to produce the sulfur dioxide, oxygen, and water.The decomposition of the sulfuric acid can be performed in four steps.

The hydrate of the metallic sulfate is crystallized from the solution and is decomposed into the metallic sulfate and water. The metallic sulfate is decomposed into the metallic oxide, oxygen, and the sulfur dioxide.
