It is argued that costly shutdowns can be minimized or eliminated through a complete understanding of the control devices along with a conscientious maintenance program and troubleshooting procedure. The electromechanical design of various types of starters, contactors, and overload relays are analyzed in terms of operation, application maintenance and troubleshooting. Specific suggestions for troubleshooting procedures are offered for various problem scenarios.<<ETX>>","PeriodicalId":174734,"journal":{"name":"Conference Record on Pulp and Paper Industry Technical Conference","volume":"245 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123666789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The changes have occurred since the company formerly part of a closely held stock corporation based in the United Kingdom, broke away from the parent organization and formed a separate US stock corporation. The changes also coincide, however, with a general rise in employee empowerment in American industry and with a burgeoning global marketplace. The results of a survey of the causes and effects of the changes in management styles are discussed. The goal of the survey was to determine whether the changes are a result of differences between American management styles and British management styles, a result of the general trend in American management styles, or some combination of the two.<<ETX>>","PeriodicalId":174734,"journal":{"name":"Conference Record on Pulp and Paper Industry Technical Conference","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130250373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Continuing adequate fire protection in control rooms requires changes in the method previously used to design and use halon systems. Programs undertaken to keep using the current halon agents, including design changes, modification of the NFPA standards and initiation of halon recycling, are described. The new extinguishing agents coming to market that provide additional options for the fire protection professional are also described. It is argued that the combination of halon initiatives and new agent development will allow ample time for conversion of existing halon systems to the next generation of fire protection technology.<<ETX>>","PeriodicalId":174734,"journal":{"name":"Conference Record on Pulp and Paper Industry Technical Conference","volume":"1938 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128802013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This approach for modeling continuous functions is similar to the common Fourier series orthogonal function set used to approximate periodic functions. It is shown that the use of orthogonal filters permits rapid transfer function identification with a minimum of prior process information while maintaining robust control under a wide range of operating conditions. The mathematical model, the development of a computer algorithm, and the results of several applications at industrial sites are presented. The basics of proportional-integral-derivative control and adaptive control are reviewed.<<ETX>>","PeriodicalId":174734,"journal":{"name":"Conference Record on Pulp and Paper Industry Technical Conference","volume":"262 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133942555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The traditional power system study, the traditional user-program interface, and the limitations of each are discussed. It is suggested that power engineers familiar with conventional system study techniques will readily adapt to the interactive-graphical method of analysis with minimum effort. Operating and plant engineers may find the technique invaluable in the study of system disturbances, for increasing operational efficiency, and for better preparing operators for critical emergencies. The advanced mathematical techniques used in this program make it an effective tool for the study of large power systems on a personal computer.<<ETX>>","PeriodicalId":174734,"journal":{"name":"Conference Record on Pulp and Paper Industry Technical Conference","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130779448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
