Publication number: 20050087233Abstract: A multi-function fluid flow control device is disclosed. A body houses a filter screen, a check valve and an orifice plate mounted on a frame which is removable from the body as a unit through an opening in the body sealed by a removable plug. The orifice plate is removable from the frame to permit different sized orifices to be fitted. An inlet in the body conducts pressurized fluid through the filter screen, through the check valve and then out through an outlet in the body, both the inlet and outlet being adapted for convenient connection to a piping network. An opening in the body in fluid communication with the inlet and sealable by a removable plug allows the screen to be flushed for removal of debris.Type: ApplicationFiled: October 28, 2003Publication date: April 28, 2005Inventor: William Reilly

Patent number: 6870025Abstract: Polycarbonates containing low or undetectable levels of Fries rearrangement products and comprising repeat units derived from one or more of resorcinol, hydroquinone, methylhydroquinone, bisphenol A, and 4,4?-biphenol have been prepared by the melt reaction of one or more of the aforementioned dihydroxy aromatic compounds with an ester-substituted diaryl carbonate such as bis-methyl salicyl carbonate. Low, or in many instances undetectable, levels of Fries rearrangement products are found in the product polycarbonates obtained as the combined result of a highly effective catalyst system which suppresses the Fries reaction and the use of lower melt polymerization temperatures relative to temperatures required for the analogous polymerization reactions using diphenyl carbonate.Type: GrantFiled: December 23, 2002Date of Patent: March 22, 2005Assignee: General Electric CompanyInventors: Patrick Joseph McCloskey, Jan Pleun Lens, James Anthony Cella, Jan Henk Kamps, Kathryn Lynn Longley, Narayan Ramesh, Warren William Reilly, Paul Michael Smigelski, Jr., Marc Brian Wisnudel

Patent number: 6723823Abstract: Mixed alkali metal salts of phosphoric acid in combination with a co-catalyst such as tetramethylammonium hydroxide (TMAH) are excellent transesterification catalysts for use in the preparation of polycarbonate from bisphenol A and diphenyl carbonate. The mixed alkali metal phosphate salts were shown by kinetic measurements made on a model system composed of p-tert-octylphenol and bis(p-cumylphenyl) carbonate to be inherently more potent catalysts than salts of phosphoric acid comprising a single alkali metal ion. In addition to providing higher rates of polymerization, the new catalysts were shown to provide polycarbonates containing reduced levels of Fries rearrangement product relative to polymerization reactions catalyzed by conventional catalyst systems such as sodium hydroxide together with TMAH co-catalyst.Type: GrantFiled: June 12, 2002Date of Patent: April 20, 2004Assignee: General Electric CompanyInventors: Patrick Joseph McCloskey, Warren William Reilly, Brian James Grimmond

Patent number: 6569985Abstract: Polycarbonates having a high level of endcapping and containing a low level of Fries rearrangement product are prepared from dihydroxy aromatic compounds, such as bisphenol A, and diaryl carbonates such as diphenyl carbonate in a two stage process involving a tetraalkyl phosphonium carboxylate catalyzed oligomerization of the reactants in a first reaction stage followed by the addition of an alkali metal hydroxide co-catalyst in the second stage of the polymerization reaction. The late addition of the co-catalyst provides improved polymerization reaction rates as judged by higher polycarbonate molecular weights. The amount of alkali metal hydroxide co-catalyst is small thus avoiding the formation of excessive amounts of Fries product. The method has been used to provide Fries product levels between 200 and 800 parts per million in polycarbonates having Mn values between 7,500 and 8,500 Daltons.Type: GrantFiled: August 8, 2001Date of Patent: May 27, 2003Assignee: General Electric CompanyInventors: Patrick Joseph McCloskey, Alberto Nisoli, Warren William Reilly

Patent number: 6399739Abstract: A melt method of preparing polycarbonate having a predetermined number average molecular weight and percent endcapping is described. A computerized process model is used to determine the reaction parameters to be employed in order to furnish the product polycarbonate possessing the desired Mn and %EC. Reaction parameters of importance include a suitable starting molar ratio of diaryl carbonate to dihydroxy aromatic compound, the most appropriate reaction time, reaction temperature and pressure ranges. The target polycarbonate is then prepared using reaction parameters indicated by the process model in a reactor which forms an element of the process model. Characteristics of the reactor which may be included in the process model include agitation rate and reflux ratio during the distillative removal of hydroxy aromatic compound formed as a by-product during the polymerization.Type: GrantFiled: August 22, 2001Date of Patent: June 4, 2002Assignee: General Electric CompanyInventors: Patrick Joseph McCloskey, Alberto Nisoli, Warren William Reilly

Patent number: 4399401Abstract: This invention covers a destructive testing procedure in which a voltage 2.5 times the rated voltage is applied to the capacitor, at a relatively high current. The resistance in series with capacitors being tested is reduced step-by-step until the resistance value is reached such that the percentage of capacitor failures on any given sample of capacitors remains constant. Thereafter, all similar capacitors are tested at that resistance value and at 2.5 times the rated voltage. Those which do not explode exhibit remarkable reliability.Type: GrantFiled: August 26, 1981Date of Patent: August 16, 1983Assignee: Centre Engineering, Inc.Inventors: Solomon Levinson, William Reilly
