  1. Lightning protection of residential AC wiring

    https://www.nist.gov/system/files/documents/pml/div684/Propagation_1978.pdf
    Lightning Protection of Residential AC Wiring Keith E. Crouch Lightning Technologies * Pittsfield, MA François D. Martzloff General Electric Company Schenectady NY f.martzloff@ieee.org Reprint, with permission, of declassified General Electric memo report MOR-78-095 Significance: Part 4 – Propagation and coupling of surges Part 8 – Coordination of cascaded SPDs Laboratory tests on the coupling of lightning current (flowing in the service drop grounded neutral conductor) onto the phase conductors, inducing overvoltages that were limited by candidate surge suppressors. While the injected lightning-simulation current was unidirectional, the induced voltages in the house wiring circuits had oscillatory components. This observation was used in support of the development of the “Ring Wave” concept that was adopted by IEEE 587 (now C62.41). Three possible types of service entranc...

    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 dev...

  6. Leakage Resilience of the ISAP Mode: A Vulgarized Summary

    Leakage Resilience of the ISAP Mode: a Vulgarized Summary Christoph Dobraunig and Bart Mennink Digital Security Group, Radboud University, Nijmegen, The Netherlands cdobraunig@cs.ru.nl, b.mennink@cs.ru.nl Abstract. ISAP is a lightweight authenticated encryption scheme that puts its fo- cus on achieving protection against implementation attacks using a minimal amount of resources. The scheme solely relies on cryptographic permutations as building blocks, which can be implemented by iterating a single round function just using different constants per round. The clever design of ISAP aims to provide protec- tion against side-channel attacks like (higher-order) differential power analysis and implementations attacks even in the absence of costly implementation-level coun- termeasures like masking. In particular, the protection against side-channel attacks just requires implementation...

    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 fo...

CRITICAL EVALUATION: This binary was studied for the first time by Gimel'shtein and Diogenov (Ref. 1) who reported the lower boundary of the isotropic liquid region in the reciprocal ternary Na,Rb/CZH30Z,N03 on the basis of visual polythermal observations. They claimed the existence of the intermediate compound Rb3(CZH30Z)ZN03 (congruently melting at 475 K [ZOZ °Cj) and of two eutectics, E1 , at 471 K (198 °C) and 100x1= 81.5, and EZ' at 454 K (181 °C) and 100x1= 35.5. In a subsequent paper on the reciprocal ternary Cs,Rb/CZH30Z,N03 (Ref. Z), the same Authors reported refined values of the coordinates of the second eutectic (467 K [19...
