Patent number: 9026413Abstract: A method of modeling phase characteristics of thermodynamic systems utilizing pseudo-properties strategy and a reduced number of variables is disclosed herein. The method describes a means of determining the probability of phase splitting of mixtures of materials at a given temperature, pressure, and composition by characterizing the functions that describe the system via pseudo-properties, and also by describing the system in n?1 or fewer variables, where n represents the number of components in the system of interest. In an embodiment, a multi-component system is characterized in one variable, thereby providing simplified thermodynamic models in a time-efficient manner. In addition, the information generated by this reduced-variable calculation can further be used as a starting point for calculations of equations of state.Type: GrantFiled: September 20, 2012Date of Patent: May 5, 2015Assignee: Invensys Systems, Inc.Inventors: Gang Xu, David Bluck

Patent number: 8165860Abstract: A system for thermodynamic modeling is provided. The system comprises a computer having a processor, a thermodynamic process simulation application, and a thermodynamic equation of state application. When executed by the processor, the thermodynamic equation of state application determines a density root based on a first and second point of departure from an equation of state and based on a first and a second extrapolation equation. The first departure point satisfies the equation ? P ? ? = ? ? P ? + ? . The second departure point satisfies the equation ? ? ( ? P ? ? - R ) + ( 1 - ? ) ? ( ? P ? ? ) ? | dp ? ? 1 = 0. The density root is determined as a pseudo-density in a phase two when the specified pressure is greater than the second departure point pressure and in a phase one when the specified pressure is less than the first departure point pressure.Type: GrantFiled: August 25, 2009Date of Patent: April 24, 2012Assignee: Invensys Systems, IncInventors: Gang Xu, David Bluck, David J.

Publication number: 20120095808Abstract: A system for process control is provided. The system comprises a computer system, a data store comprising a plurality of data sets, each data set associated with operating conditions of a plant at a particular time, a first application, and a second application, the first and second applications executed by the computer system. The first application simulates operation of the plant in accordance with first principles and based on one of the data sets. The second application receives plant simulation data from the first application, aggregates plant historical data about the plant from a plurality of sources, associates the plant simulation data and the plant historical data to components of the plant, analyzes the plant simulation data and the plant historical data, and visually presents an information produced by the analysis of the plant simulation data and the plant historical data.Type: ApplicationFiled: October 15, 2010Publication date: April 19, 2012Applicant: INVENSYS SYSTEMS INC.Inventors: James Kattapuram, David Bluck

METHOD FOR GUARANTEEING CONSISTENCY OF FUNCTIONAL PARTS ACROSS A SOFTWARE INSTALLATION IN A COMPUTER
Publication number: 20100122123Abstract: A method for guaranteeing consistency of functional parts across a software installation in a computer that is platform and language independent. Specifically, each software installation will contain a part, for example a DLL that exports a function or variable, which is available to other parts in the installation. All other parts in the installation, for example, executable files and other DLLs, will reference the exported resource. The name of the exported resource should evoke a particular software level and be specific to the software installation it belongs to. All other software installations on the same computer will follow this practice. Thus, all parts in a software installation will effectively reference a software level (via an exported resource). When the multiple parts of software are loaded into computer memory prior to execution of the software, the operating system will attempt to resolve references to the exported resource.Type: ApplicationFiled: November 10, 2008Publication date: May 13, 2010Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Simon David BLUCK, Jason Colin EDMEADES, Gary Patrick LONGERSTAEY, Stuart Jeffrey REECE -
Patent number: 6132867Abstract: A gel profile article comprising a multi-filament yarn carrier carrying an elongate body of gel which encloses more than 50%, preferably more than 75%, more preferably substantially all, of the perimeter of the carrier as viewed in transverse cross-section, wherein the carrier is at least partly composed of synthetic polymeric material, preferably polyester filaments (e.g. polyethylene terephthalate) or spun yarns of a co-mingled blend of polyacrylonitrile staple fibres and polyamide staple fibres ("baby wool"), the proportion of polyamide preferably being at least 30%, more preferably 40-60%, by weight of the said spun yarn(s). The gel is preferably melt-coated, especially pressure-extruded, around the carrier at a gel temperature less than the softening temperature of at least a component of the carrier, and the selected class of carrier materials enhances the processability, cohesion, and appearance of the resulting profile.Type: GrantFiled: September 17, 1998Date of Patent: October 17, 2000Inventors: Philip James Hammond, Michael John Percy, David Bluck
