The flux vector method discussed uses indirect field orientation techniques to determine the magnitude and direction of the air-gap magnetic flux in the motor in order that the stator current can be adjusted, thus providing the required torque. This method effectively provides separate control over the field-producing and torque-producing components of total stator current to give DC machine performance capabilities to the induction motor. It is felt that any application requiring high performance speed, positioning or torque regulation in a hazardous environment will benefit from the lower cost of induction motor use. Continuous ability to produce 100% rated torque and 150% holding for intermittent periods should provide many applications with increased reasons to utilize this technology.<<ETX>>","PeriodicalId":420310,"journal":{"name":"Conference Record of 1992 Forty-Fourth Annual Conference of Electrical Engineering Problems in the Rubber and Plastics Industries","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131970558","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}

In looking for a cause for accelerated battery wear-out, a study of the electrical environment was made in order to identify the differences between the relatively new UPS applications and the older telecommunications applications. The types of sites from which data were taken are: central office and PBX telecom, single-unit UPS, multiple-unit UPS with individual battery systems, and multiple-unit UPS with a shared battery system. In most instances the load on the DC system was unknown. Several UPS brands were tested to get a representative sample. The author describes the data acquisition system used and data reduction issues and proposes a standard method for data acquisition and a recommended instrument list.<<ETX>>","PeriodicalId":420310,"journal":{"name":"Conference Record of 1992 Forty-Fourth Annual Conference of Electrical Engineering Problems in the Rubber and Plastics Industries","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126830320","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 author concludes customers will justify Machine Vision Technology based on greater manufacturing yield, along with improved quality or labor-savings.<<ETX>>","PeriodicalId":420310,"journal":{"name":"Conference Record of 1992 Forty-Fourth Annual Conference of Electrical Engineering Problems in the Rubber and Plastics Industries","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127314143","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}

There is considerable confusion in industry regarding which spills and leaks are covered, how the USEPA mandates that spills and contamination be cleaned, and how PCB equipment and materials need to be disposed of. The author reviews the PCB spill cleanup policy and then discusses methods for disposal available to owners. Some methods of legal disposal, allowed under the regulations, do not eliminate risks, but may actually increase them. An alternative that eliminates the long term exposure risks caused by disposal of PCB-containing equipment is proposed.<<ETX>>","PeriodicalId":420310,"journal":{"name":"Conference Record of 1992 Forty-Fourth Annual Conference of Electrical Engineering Problems in the Rubber and Plastics Industries","volume":"464 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122494767","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}
