Patent number: 9454283Abstract: In an embodiment, a mechanism for visualizing a graphical model in three dimensions is discussed. An executable graphical model is obtained that includes a hierarchy of model levels that include a top level. The hierarchy includes multiple components. A three-dimensional (3D) view of the graphical model is displayed that provides views of a first and second component at a first and second depth. A graphical indicator is generated in the view of the top level of the graphical model that is associated with the first component and also generated in the view of the second component. A control alters a user perspective of a view that includes at least one of the components in the graphical model.Type: GrantFiled: June 11, 2008Date of Patent: September 27, 2016Assignee: The Mathworks, Inc.Inventors: Jay Ryan Torgerson, Simon Greenwold, Claudia Wey, Eric Pressman, Matthew Englehart

Publication number: 20070117990Abstract: Disclosed herein is a method for purification of dianhydrides comprising a substantial amount (10000 ppm or more) of at least one metal salt. In one aspect the method is useful for the purification of dianhydrides prepared by the reaction of a halophthalic anhydride with a metal carbonate and may be optionally catalyzed by a phase transfer catalyst. The purification of the dianhydrides may be accomplished by hydrolyzing the dianhydride metal salt mixture directly to a tetraacid with an inorganic acid, followed by separating the impurities from an aqueous phase, and subsequently heating the tetraacid to effect ring closure to form a purified dianhydride having less than 50 parts per million metal halide and lower levels of other residual impurities. In one aspect the method is highly effective in removing phase transfer catalyst impurities such as hexalkylguanidinium halides initially present in the dianhydride undergoing purification.Type: ApplicationFiled: November 22, 2005Publication date: May 24, 2007Applicant: General Electric CompanyInventors: Eric Pressman, Albert Stella, Beatriz Bernabe, Lioba Kloppenburg, Lee Bergman

Publication number: 20050085656Abstract: A method of increasing the amount of diphenylcarbonate produced per amount of catalyst consumed in a phenol carbonylation process is described. Phenolic carbonylation produces water as a reaction product which reduces the turnover number (TON) of the catalyst. A mixture of a phenolic precursor, a base containing catalyst and co-catalyst components and at least one chemical additive comprising a halide or hydroxide of alkali metal or alkaline earth metal when carbonylated together under specific conditions increases the turnover number (TON) and water resistivity of a palladium catalyst. The metal halide likely makes the catalyst less susceptible to degradation by water hence increasing the reaction yield per weight of catalyst consumed.Type: ApplicationFiled: October 15, 2003Publication date: April 21, 2005Inventors: Grigorii Soloveichik, Timothy Chuck, Kirill Shalyaev, Eric Pressman, Peter Bonitatebus

Publication number: 20050075519Abstract: A method for preparing and isolating dihydroxybiaryl compounds, such as 4,4?-dihydroxybiphenyl, is disclosed. The alkali metal salt of the dihydroxybiaryl compound is protonated with the monohydroxyaryl halide compound initially used in the reductive coupling reaction which produced the alkali metal salt. In addition, the alkali metal salt of the monohydroxyaryl halide compound is produced by the process, which can then be recycled as the base and monohydroxyaryl halide in a further reductive coupling reaction to form the alkali metal salt of the dihydroxybiaryl compound.Type: ApplicationFiled: October 7, 2003Publication date: April 7, 2005Applicant: General Electric CompanyInventors: John Ofori, Ben Patel, Eric Pressman

Publication number: 20050059843Abstract: A method for preparing hydroxyaromatic compounds brominated in the para-position, such as p-bromophenol, is disclosed. The method yields overall high process selectivity through isomeric equilibration and separation of the brominated products, thereby eliminating the need for high para selectivity in the products of catalytic oxybromination reactions of hydroxyaromatic compounds using oxygen, a bromine source, and an acidic medium in the presence of a metal catalyst. Furthermore, the invention provides an efficient method for recycling the metal catalyst, as well as reagents used in the bromination, to further reactions.Type: ApplicationFiled: September 17, 2003Publication date: March 17, 2005Applicant: General Electric CompanyInventors: Eric Pressman, Jonathan Male, Ryan Mills, John Ofori
