Abstract: TITLE          DEPOSIT SUPPRESSION IN THE CORE OF WATER-COOLED                NUCLEAR REACTORS                            INVENTOR                      Kenneth A. Burrill ABSTRACT OF THE DISCLOSURE         In pressurized water-cooled nuclear reactors, the formation of deposits on surfaces in the core of the reactor, e.g. on fuel sheaths, is suppressed by maintaining in the circulating pressurized water, a high concentration of ammonia ranging from about 120 to about 200 mg NH3/kg water.          Crevice corrosion of the fuel sheaths is avoided, even under localized boiling conditions, since the pH never attains a corrosively high level.  The crevice corrosion danger with lithium can be reduced by replacing part of the lithium with ammonia.

Abstract: ABSTRACT OF THE DISCLOSURE           A solventless, fast-setting anaerobic adhesive composition comprises two monomer parts which are adapted to be copolymerized anaerobically at ambient temperature between opposing surfaces to form a high-strenght bond thereto. One port comprises a multifunctional acrylate monomer and the other an N-vinylamide monomer. The formu-lation also includes a redox system consisting of oxidizing and reducing agent components for initiating polymerization between said monomers. The oxidizing agent of the redox system may be present in either one of said parts, prefer-ably with the multifunctional acrylate. The reducing agent is present in the other part, ususally the N-vinylamide. Upon anaerobic admixing of the respective parts of the com-position at ambient temperature, the oxidizing and reducing agents react to generate free radicals which initiates co-polymerization of the monomers to form the desired high-strength adhesive bond to said surfaces.

Title: Two-flame burner for flame photometric detection
Inventor: PATTERSON PAUL L
IPC: G01J3/10
Filed: 1978-02-27
Granted: 1981-01-13
Abstract: ABSTRACT A two flame burner is used in a flame photometric detector for analyzing a a sample material.   The sample material is introduced via a first conduit structure into a hydrogen-rich first flame, and the combustion products and excess hydrogen from the first flame are passed via a second conduit structure into an oxygen-containing environment.  A second flame is maintained at the exit end of the second conduit structure.  The first and second conduit structures are composed of material that does not contribute to the coloration of the second flame during operation of the detector.  Particular constituents of the sample material are detected by observing the presence of colors in the second flame indicative of the constituents.  For example, the presence of sulfur is indicated by a blue coloration, and the presence of phosphorus is indicated by a green coloration. The presence of nitrogen indicated by a coloration of the second flame resulting from a chemiluminescent molecular recombination of nitric oxide and oxygen atoms to form nitrogen dioxide molecules. The presence of any hydrocarbon can be indicated by a flame coloration resulting from a chemical reaction indicative of elemental carbon.
