Publication number: 20120078010Abstract: Disclosed is a process for the extractive recovery of an acid catalyst from an aqueous mixture of glycolic acid with an extraction solvent comprising a tertiary amine or an onium carboxylate compound, a modifier, and a diluent. The acid catalyst, which can comprise strong acids such as sulfuric acid, alkyl sulfonic acids, and fluoroalkyl sulfonic acids, can be recovered by back extraction with aqueous formaldehyde and recycled to a process for the preparation of glycolic acid by the acid-catalyzed carbonylation of formaldehyde.Type: ApplicationFiled: September 23, 2010Publication date: March 29, 2012Applicant: EASTMAN CHEMICAL COMPANYInventors: Scott Donald Barnicki, Stephen Neal Falling, Jeffrey Scott Kanel, Robert Sterling Kline, Peter Borden Mackenzie

Patent number: 7987766Abstract: The hydraulic cylinder apparatus has a crescent shaped length housing a piston of like shape. The crescent shape provides for fit into constrained spaces where a fully cylindrical cylinder cannot fit. Multiple crescent shaped case ring lands with case rings seal the length of the piston proximal to the top of the case. The plurality of piston ring lands and piston rings seal the sliding piston to the walls of the case's internal hydraulic fluid well. The numerous ports of the apparatus, both upper and lower, provide for more convenient application than would otherwise be provided. Hose routing can thereby be best suited to a particular application. An added advantage of the apparatus is the negation of piston and mount rotation, a feature not typically possible with cylindrical hydraulic cylinders.Type: GrantFiled: June 3, 2008Date of Patent: August 2, 2011Inventor: Robert Sterling Price

Patent number: 6018061Abstract: A process for recovering 3,4-epoxy-1-butene from a vapor phase catalytic oxidation reactor effluent where 1,3-butadiene is reacted with oxygen over a silver catalyst, the process includes the steps of contacting the reactor effluent with an absorbent in an absorber and vaporizing in the absorber an effective amount of a non-reactive coolant to cool the absorber to a temperature of less than about 40.degree. C. and a pressure of less than about 4 bar. Advantageously, the vaporization of the non-reactive coolant proximate to the absorber allows the absorber to be operated at lower temperatures and pressures than heretofore possible and provides a further advantage of allowing higher O.sub.2 concentrations in the feed to the epoxidation reactor.Type: GrantFiled: May 5, 1999Date of Patent: January 25, 2000Assignee: Eastman Chemical CompanyInventors: Scott Donald Barnicki, Robert Sterling Kline, James Alan Kenning, Anthony Dominick Messina

Patent number: 5777539Abstract: An inductor or transformer uses a multilayer printed circuit board to form the conductor turns. Each layer comprises a dielectric sheet and a conductor printed on the sheet. Each of the conductors has approximately the same shape as each other (such as circular or rectangular), is superimposed on the other conductors and is substantially closed on itself (with a gap to separate the two ends). A multiplicity of through-hole vias are evenly spaced around the conductors and pass through the multiplicity of layers. Successive vias make an electrical connection between successive pairs of adjacent conductors such that current passes in the same direction through all of the conductors. Each layer provides (N-1)/N turns such that N layers provide N-1 complete turns. A ferrite core material passes through a hole in the printed circuit board within the conductors.Type: GrantFiled: September 27, 1995Date of Patent: July 7, 1998Assignee: International Business Machines CorporationInventors: Donald Victor Folker, Randhir Singh Malik, Robert Sterling Rowland
