  • Publication number: 20120245396
    Abstract: A process for producing ethanol is disclosed, comprising the steps of hydrogenating acetic acid in a reactor in the presence of a catalyst to form a crude ethanol product, separating at least a portion of the crude ethanol product in a column into a first distillate comprising ethanol and a first residue comprising acetic acid and water, wherein a substantial portion of the water in the crude ethanol product that is fed to the column is removed in the first residue, and separating a portion of the ethanol mixture stream to the second distillation column to yield an ethanol product sidedraw, second residue comprising water and a second distillate comprising ethyl acetate. The water content of the ethanol product sidedraw may be further reduced to yield a stream having reduced water content.

  • Publication number: 20120242738
    Abstract: A system for adjusting page placement on a continuous feed duplex print engine. A processor receives, from a print engine, ejector data regarding first and second defective ink ejectors including respective transverse positions for the ink ejectors. A memory element stores the ejector data. The processor: receives print data regarding first and second pages to be printed on the first and second sides, respectively, of the continuous sheet, including transverse positions for respective pixels on the pages; creates, using the print data, first and second logical pages for the first and second pages; and, creates, using the ejector data, first and second logical sheets including the first and second logical pages by transversely positioning the first and second logical pages such that the first and second defective ink ejectors and the positions for the respective pixels on the first and second pages are out of alignment in the process direction.

  • Publication number: 20120243472
    Abstract: A Mobile Switching Center (MSC) of a CDMA telecommunications wireless network which includes a CDMA mobile station (MS), a CDMA base station (BS), a CDMA HLR, and an Unstructured Supplementary Service Data (USSD) Gateway. The MSC is capable of receiving a MS initiated USSD request from the BS, determining if the subscriber is authorized to use USSD services and if authorized constructing a MAP message containing the USSD Request which is then sent to a USSD Gateway identified by subscriber profile information received during registration. The MSC is also capable of identifying MAP messaging it receives that contains USSD messaging, constructing an IOS message that contains the USSD messaging and sending the IOS message to the BS which in turn sends it to the MS.

  • Publication number: 20120241913
    Abstract: An article including a microelectronic substrate is provided as an article usable during the processing of the microelectronic substrate. Such article includes a microelectronic substrate having a front surface, a rear surface opposite the front surface and a peripheral edge at boundaries of the front and rear surfaces. The front surface is a major surface of the article. A removable annular edge extension element having a front surface, a rear surface and an inner edge extending between the front and rear surfaces has the inner edge joined to the peripheral edge of the microelectronic substrate. In such way, a continuous surface is formed which includes the front surface of the edge extension element extending laterally from the peripheral edge of the microelectronic substrate and the front surface of the microelectronic substrate, the continuous surface being substantially co-planar and flat where the peripheral edge is joined to the inner edge.
