Patent number: 11922546Abstract: Methods and apparatus to generate and display trends associated with a process control system are disclosed. An example apparatus includes memory, machine readable instructions, and processor circuitry to execute the instructions to generate a first graphical user interface. The first graphical user interface to include a graphical representation of a component in a process control system. The processor circuitry to generate a second graphical user interface. The second graphical user interface to include a chart region with a trend represented therein. The trend indicative of values of a process parameter of the process control system over a period of time. The processor circuitry to automatically generate the trend in the chart region in response to a graphical element being dragged and dropped from the first graphical user interface to the second graphical user interface.Type: GrantFiled: May 25, 2022Date of Patent: March 5, 2024Assignee: FISHER-ROSEMOUNT SYSTEMS, INC.Inventors: Denis David, Monja Lajoie, Jessica Siu Liu, Karen Chau Johnson, Cody Troyer, Ian Nadas, Duane L. Harnish, Simran Ahuja, Amanda McConville, Terry P. Vallery, Jr.

Publication number: 20160166962Abstract: Filter media suitable for various applications and related components, systems, and methods associated therewith are described. The filter media may include a composite filter media structure having a substrate and at least one fine fiber layer. The fine fiber layer may include a plurality of glass fibers having an average fiber diameter of less than 2 microns; or, at least 70% by weight of the glass fibers within the fine fiber layer has a fiber diameter of less than 2 microns. The fine fiber layer may further include a fluorochemical composition, an organosilicon composition and may optionally include a binder composition that comprises less than 2% by weight of the fine fiber layer. The filter media may exhibit both a relatively high gamma and favorable mechanical properties. The filter media may be produced by forming a substrate on the surface of a wire in a wet laid process, and forming a fine fiber layer on the substrate while the substrate is on the wire.Type: ApplicationFiled: December 11, 2015Publication date: June 16, 2016Applicant: Hollingsworth & Vose CompanyInventors: David F. Sealey, Sudhakar Jaganathan, Randall B. Keisler, David Vallery

Patent number: 8956504Abstract: Systems and methods for forming fiber webs, including those suitable for use as filter media and battery separators, are provided. In some embodiments, the systems and methods involve a first system for forming a fiber web (e.g., a wet laid system or non-wet laid system) and additionally one or more coating units. The first system for forming a fiber web may be used to form one or more fibrous layers of the fiber web, and the coating unit may be used to form an additional fibrous layer of the fiber web. In some embodiments, the systems and methods can be used to form fiber webs having a gradient in a property across a portion of, or the entire, thickness of the fiber web.Type: GrantFiled: May 8, 2014Date of Patent: February 17, 2015Assignee: Hollingsworth & Vose CompanyInventor: David Vallery

Patent number: 8877011Abstract: Systems and methods for forming fiber webs, including those suitable for use as filter media and battery separators, are provided. In some embodiments, the systems and methods may involve the use of one or more fiber mixtures to form a fiber web. The fiber mixtures may flow in different portions of a system for forming a fiber web that may be separated by a lamella, and may join at a fiber web forming zone to produce a fiber web having multiple layers. The amount of mixing of the fiber mixtures at or near the fiber web forming zone may be controlled to produce fiber webs having different structural and/or performance characteristics. In some embodiments, the systems and methods described herein can be used to form fiber webs having a gradient in a property across a portion of, or the entire, thickness of the fiber web.Type: GrantFiled: May 11, 2012Date of Patent: November 4, 2014Assignee: Hollingsworth & Vose CompanyInventors: Douglas M. Guimond, Mark S. Millar, David Vallery, Milind Godsay
