Patent number: 7898786Abstract: A system and method for providing an intrinsically safe (IS) galvanically isolated barrier device. An IS barrier device provides IS galvanic isolation between a non-IS system and an IS system using a two-stage approach. In the first stage, a non-galvanically isolated IS barrier limits energy of electrical transmissions received from the non-IS system to convert such electrical transmissions into IS transmissions. In the second stage, the IS transmissions are transmitted through a galvanic isolator to the IS system to galvanically isolate the IS system from the non-IS system. A digital monolithic isolator cannot be IS certified to be the single bridge between IS and non-IS systems, however, it can be used in a certifiable fashion to isolate between IS systems.Type: GrantFiled: August 28, 2007Date of Patent: March 1, 2011Assignee: Siemens Industry, Inc.Inventor: Glen E. Schmidt

Patent number: 7863055Abstract: The present invention is a method and apparatus for sampling a high-temperature gaseous process stream containing components with high boiling points. The sampling system is especially suited for instruments having extremely low pressure chambers, such as mass spectrometers. The invention reduces the condensation of high boiling point components of the sample in the sampling system without the necessity of maintaining extremely high temperatures. The gaseous sample is passed through an orifice from the high temperature stream into a lower-temperature zone of the sampling system where a low pressure is maintained by a vacuum pump. The low pressure reduces the boiling point of the sample components so they may be maintained in a gas phase without excessive heating. The low pressure sample is then introduced into an instrument chamber through a sample introduction valve.Type: GrantFiled: July 11, 2007Date of Patent: January 4, 2011Assignee: Siemens Industry, Inc.Inventors: Dean Vinson Davis, Kenneth L. Gallaher, Eugene L. Kesselhuth, Jeffrey Scott Spaulding
