    COMPONENTS: Systems with Common Anion EVALUATOR: 105 (1) (2) Potassium butanoate (potassium (C4H702)2K2; [589-39-9] Magnesium butanoate (magnesium (C4H702)2Mg; [556-45-6] butyrate); Franzosini, P., Dipartimento di Chimica Fisica, butyrate); Universita' di Pavia (ITALY). CRITICAL EVALUATION: This binary was studied only by Pochtakova (Ref. 1) who, on the basis of her visual polythermal and DTA results, asserted the occurrence of a congruently melting intermediate compound, i.e., (C4H702)4K2Hg, forming (possibly simple) eutectics with either component. Component I, however, goes through the liquid crystalline state before transformation into a clear melt. Therefore, the topology of the phase diagram at 0 5 100x2 5 50 should be described more correctly with reference to Scheme B.l of the Preface, and an invariant type M'p (undetected by Pochtakova) should also exist. The following points...
  2. Cascading surge-protective devices: Options for effective implementations (1992)

    https://www.nist.gov/system/files/documents/pml/div684/Coordination_1992.pdf
    Cascading Surge-Protective Devices: Options for Effective Implementations François D. Martzloff National Institute of Standards and Technology Gaithersburg MD f.martzloff@ieee.org Jih-Sheng Lai Power Electronics Applications Center Knoxville TN Paper presented at PQA'92 Conference, Atlanta, 1992 Significance Part 8 – Coordination of cascaded SPDs The early nineties were marked by the emergence of concerns about the coordination of cascaded SPD as the concept of “Whole-house protection” was gaining popularity. However, it appeared that the selection of service entrance SPDs and point-of-use plug-in SPDs was not an integrated process, hence some possibility that the expected coordination might not be achieved. On the other hand, if a well-designed combination could be implemented by a single authority responsible for the selection of the...

    DETERMINATION OF NITROGEN SOLUBILITY IN SWERPRESSURIZED HFC-227ea, HFC- 236fa, AND HFC-125 Chien-Ping Chai Kao and Ralph N. Miller E. 1. DuPont de Nemours and Company INTRODUCTION Bromochlorofluorocarbons (halons), developed in the 1930s, have unique properties. They are low in toxicity, nonflammable, noncorrosive, and compatible with other materials. In addition, they have therm- odynamic and physical properties that make them ideal fire extinguishing agents and explosion suppres- sants for protection of high-value equipment. They are used in handheld portable extinguishers, total- flooding systems, and local application systems. The atmospheric stability of these compounds, coupled with their bromine and/or chlorine content, has linked them to depletion of the earth's protective ozone layer. As a result, these compounds have been phased out of production. DuPont has developed alterna...
  4. Revisiting reality checks on the surge environment

    https://www.nist.gov/system/files/documents/pml/div684/Revisiting.pdf
    AJWG-77B(Martzloff/Erlanaen)0l November 1995 International Electrotechnical Commission Technical Committee 77 - Electromagnetic Compatibility Subcommittee 778 - High-Frequency Phenomena Contribution to: Joint Working Group on Overvoltage Control From: Frangois D. Martzloff Revisiting reality checks on the surge environment In our quest for data on the frequency of occurrence and level of threat of overvoltages, we should not overlook some "reality checks" that can be applied to proposals for characterizing the surge environment. In the white paper (Martzloff/London)l of July 1995, four examples of reality checks were cited to inject some perspective in the process and avoid excessive conservatism in assessing the need for high current requirements for SPDs installed in buildings. Two of these raised questions from the AJWG, which I will attempt to clarify in this follow-up white ...
