Pressure Control Equipment 1 Indication of replacement of elements, inspection items The following describes the general contents of the element replacement and regular check. Indication of replacement of air filter, inspection items Replacement standards <Element replacement> The differential pressure (pressure drop) between the primary side and secondary side reaches 0.1 MPa. Even when any pressure differential does not occur, replace the element every two years. Inspection items 1) Checking of external leak or case crack. If the case is cracked, this may lead to a serious accident, such as case rupture. So, replace the case im- mediately and locate the cause. If the case is contaminated significantly and the internal status cannot be checked, clean the case with neutral detergent. At this time, never use solvent or machine cleaning solu- tion. 2) Functional inspection of drain discharge mechanism Check that the drain mechanism functions correctly without fail and that the drain is discharged periodi- cally for manual type. If the drain is produced excessively, a trouble may occur in the purification equipment on the upstream side. Probable troubles (Reference) Refer to the "Troubleshooting" for air filter/auto drain. (p. 246) Regulator inspection items Inspection items Check the set pressure level before starting up the equipment. If the set pressure level is beyond the speci- fied range, locate the cause. (Be sure to locate the cause before starting the readjustment.) Additionally, check the following points dur- ing periodic inspection. 1) Functional inspection and grease-up of the valve body (including the valve guide) 2) Functional inspection and grease-up of the valve spring Check for rust, breakage, or permanent settling. 3) Checking of setting function and relief function (Check the functions by increasing or decreasing the setting.) Probable troubles (Reference) Refer to the "Troubleshooting" for regulator. (p. 247) Lubricator inspection items Inspection items q Inspection of dripping volume: Inspect this item when starting the equipment operation. w Check the oil status inside the case.

Who was Clovis, first King of France? 20 IV Results 34 V Bibliography 40 Acknowledgements 41 VICTORINUS (coin portrait) 2 I Was Emperor VICTORINUS the historical model for SIEGFRIED of the Nibelungen Saga? The mythical figure of Siegfried from Xanten (Colonia Ulpia Traiana), the greatest hero of the Germanic and Nordic sagas, is based on the real Gallic emperor Victorinus (meaning “the victorious”), whose name can be translated into Siegfried (Sigurd etc.), which means “victorious” in German and the Scandinavian languages. The reign of Victorinus is conventionally dated 269-271 AD. He is one of the leaders of the so-called Gallic Empire (Imperium Galliarum; 260-274 AD), mostly known from Historia Augusta (Thayer 2018), Epitome de Caesaribus of Aurelius Victor (Banchich 2009), and the Breviarum of Eutropius (Watson 1886). The capital city of this empire was Cologne, 80 km south of Xanten. Trier and Lyon were additional administrative centers. This sub-kingdom tried to defend the western part of the Roman Empire against invaders who were taking advantage of the so-called Crisis of the Third Century, which mysteriously lasted exactly 50 years (234 to 284 AD). Yet, the Gallic Empire also had separatist tendencies and sought to become independent from Rome. The bold claim of Victorinus = Siegfried was put forward, in 1841, by A.

    Beyond the River, under the Eye of Rome Ethnographic Landscapes, Imperial Frontiers, and the Shaping of a Danubian Borderland by Timothy Campbell Hart A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy (Greek and Roman History) in the University of Michigan 2017 Doctoral Committee: Professor David S. Potter, Co-Chair Professor Emeritus Raymond H. Van Dam, Co-Chair Assistant Professor Ian David Fielding Professor Christopher John Ratté © Timothy Campbell Hart [email protected] ORCID iD: 0000-0002-8640-131X For my family ii ACKNOWLEDGEMENTS Developing and writing a dissertation can, at times, seem like a solo battle, but in my case, at least, this was far from the truth. I could not have completed this project without the advice and support of many individuals, most crucially, my dissertation co-chairs David S. Potter, and Raymond Van Dam. Ray saw some glimmer of potential in me and worked to foster it from the moment I arrived at Michigan. I am truly thankful for his support throughout the years and constant advice on both academic and institutional matters. In particular, our conversations about demographics and the movement of people in the ancient world were crucial to the genesis of this project. Throughout the writing process, Ray’s firm encouragement towards clarity of argument and style, while not always what I wanted to hear, have done much to make this a stronger dissertation. David Potter has provided me with a lofty academic model towards which to strive. I admire the breadth and depth of his scholarship; working and teaching with him have shown me much worth emulating.

    THE PTOLEMIES AND THE 3rd CENTURY B.C.E. CERAMIC ASSEMBLAGE Melanie Godsey A thesis submitted to the faculty at the University of North Carolina at Chapel Hill in partial fulfillment of the requirements for the degree of Master of Arts in the Department of Classics. Chapel Hill 2017 Approved by: Jennifer Gates-Foster Sheila Dillon Donald Haggis © 2017 Melanie Godsey ALL RIGHTS RESERVED ii ABSTRACT Melanie Godsey: The Ptolemies and the 3rd Century B.C.E. Ceramic Assemblage (Under the direction of Jennifer Gates-Foster) The Ptolemaic political, military, and economic interests in the 3rd century B.C.E. Aegean and Greek mainland fostered cultural exchange. I examine the ceramic evidence from two sites to assess the network of interaction and its impact on the function and production of Hellenistic pottery types. The ceramic assemblage from Eretria, a city with a historically Greek affiliation, will serve as a point of comparison for the evidence from Koroni, a Ptolemaic site in Attika. The ceramic assemblage from Koroni tells us three things: 1) the fine ware indicates that the Ptolemies had already begun to be involved in what will become the Hellenistic koine, 2) Koroni was not directly linked with Athens, which throws into question the function of the site, and 3) the Ptolemaic intervention in and then withdrawal from Attika and the Aegean was one reason behind the fluctuation in the market for Attic black gloss pottery. iii TABLE OF CONTENTS LIST OF FIGURES ...............................................................................................................................

    A REASSESSMENT OF GALLIENUS’ REIGN TROY KENDRICK Bachelor of Arts, University of Lethbridge, 2014 A Thesis Submitted to the School of Graduate Studies of the University of Lethbridge in Partial Fulfilment of the Requirements for the degree MASTER OF ARTS History Department University of Lethbridge LETHBRIDGE, ALBERTA, CANADA © Troy Kendrick, 2014 Abstract This thesis examines and reassesses the reign of the Roman emperor Gallienus in the mid-third century CE. Specifically, this paper analyses Gallienus’ military and administrative policies, his conception of his emperorship, and the influence his policies had on his successors.Gallienus ruled over the Roman Empire during a period of unprecedented calamities. The misfortunes of the Roman Empire during this period, and the biases against Gallienus in the writings of the ancient Latin authors, left a less-than-favorable impression of Gallienus’ reign. However, a re-evaluation of Gallienus and his policies unveils a remarkably capable emperor, who should be credited with not only saving the Roman Empire from complete collapse, but laying the foundation for the Empire’s recovery in the late third century CE. iii Acknowledgements I would like offer my thanks to committee members David Hay and Kevin McGeough for their assistance and comments regarding my thesis. I would especially like to thank my supervisor, Christopher Epplett, for the invaluable assistance, encouragement, and patience he has extended to me throughout the entire writing process.

  • Odaenathus' Titulature and the Use of the Imperium Maius
    DAVID POTTER PALMYRA AND ROME: ODAENATHUS’ TITULATURE AND THE USE OF THE IMPERIUM MAIUS aus: Zeitschrift für Papyrologie und Epigraphik 113 (1996) 271–285 © Dr. Rudolf Habelt GmbH, Bonn 271 PALMYRA AND ROME: ODAENATHUS' TITULATURE AND THE USE OF THE IMPERIUM MAIUS The year 260 AD was not a good one for P. Licinius Egnatius Gallienus. Sometime in the early sum- mer, Sapor I of Persia captured his father, and co-emperor, in a battle outside of Edessa. Sapor went on to ravage considerable portions of Cilicia and Cappadocia before his over-extended forces were attacked by the remnants of the Roman army under the command of officers named Callistus and Macrianus. Sapor was further humiliated when Odaenathus, lord of Palmyra, attacked him as he was drawing his forces back towards his own country. These victories did little to help Gallienus, who also lost a son in a revolt that broke out on the Rhine shortly after the capture of his father. Macrianus celebrated his vic- tory by proclaiming his own two sons emperor, and he appears to have been assisted in this by both Cal- listus and Odaenathus. Two years later Macrianus and one of his sons took an army into the Balkans to wrest the throne from Gallienus. They failed in the attempt and Odaenathus, who appears to have been a person of con- siderable political acumen, decided to attack their surviving supporters at Emesa. At this point we are told that Gallienus made Odaenathus !trathgÒ! of the whole east, and the contemporary author of an oracular text observes: êrjei ÑRvma¤vn, P°r!ai d' ¶!!ont' élapadno¤.1 The issue is of Odaenathus' position after 262 is of importance for several reasons.

  • The Antonine Plague and the 'Third-Century Crisis'
    THE ANTONINE PLAGUE AND THE ‘THIRD-CENTURY CRISIS’ Christer Bruun* Introduction: the Antonine plague This paper will discuss two broad topics, the plague under Marcus Aurelius and the development of the Roman empire from the late second century onwards, and the relations between these two phe- nomena. The English word ‘plague’ is here used in the general sense of ‘potentially lethal epidemic disease’. I do not want to imply that we are dealing with the ‘bubonic plague’ caused by the yersinia pestis bacillus (discovered or identi ed in 1894),1 as today no one knows for certain what disease spread through the Roman world from 165 C.E. onwards, regardless of much speculation on the matter.2 The role of the plague among the causes of the ‘third-century crisis’ The ‘third century crisis’ is in itself a debated topic, as is made abun- dantly clear in other contributions in this volume. To save time and space, I will simply take it for granted that changes affected the Roman world from the reign of Marcus Aurelius onwards which in certain * Warm thanks are due to Lukas de Blois, Olivier Hekster, Gerda de Kleijn and the other organizers of the colloquium in Nijmegen.

  • Chapter Seventeen the Establishment of Christendom, 235
    Chapter Seventeen The Establishment of Christendom, 235 to 430 In 235 Christianity was still a minor subculture in the Roman empire, and also in the adjacent lands. More people worshiped in the Judaean synagogues than in the Christian churches, and the great majority of the population belonged neither to a synagogue nor a church: in the early third-century empire perhaps only one person in ten worshiped God. By 430, when Augustine died soon after finishing his City of God, the Roman emperors had been Christian for more than a hundred years, and most people in the empire, in Armenia, and even in Ethiopia were Christians. The establishment of Christianity coincided with a series of Roman military and political disasters and ultimately with the empire‟s collapse in the Latin west. The rise of the Sassanids, and the first crisis of the Roman empire (235-284) In the third century, after more than four hundred years of security, the Roman empire came close to disintegration. Specifically, in the years between the death of Alexander Severus (235) and the accession of Diocletian (284) the empire was battered by external enemies and was drained internally by political chaos and by monetary collapse. The troubles of 235-284 were in many ways a harbinger of what was to come in the late fourth and fifth centuries, when the empire‟s western provinces were lost, a chain of events traditionally called “the fall of Rome.” The Romans‟ troubles began with an apparent success. Between 194 and 198 Septimius Severus led two victorious expeditions against the Parthian empire, and the second culminated in the burning of the Parthian capital, Ctesiphon, on the east bank of the Tigris river.
