Patent number: 8394936Abstract: Disclosed are methods and compositions for conducting assays of samples utilizing polymerase chain reactions (“PCRs”) in the detection of serotypes of Chlamydia trachomatis capable of causing lymphogranuloma venereum (“LGV”). These assays take advantage of a deletion occurring in the cytotoxin gene locus specific to the L I, L II, and L serotypes. Each of these assays employs a first primer having a nucleotide sequence flanking one side of the deletion point and a second primer having a nucleotide sequence flanking the other side of the deletion point, wherein the first primer and the second primer are capable of hybridizing respectively to the plus strand and the minus strand of the genome of Chlamydia trachomatis during the PCR. Synthesis during the PCR of a sequence-specific amplicon containing this deletion point indicates that the sample contains nucleic acid specific to an LGV-causing serotype of Chlamydia trachomatis.Type: GrantFiled: May 18, 2006Date of Patent: March 12, 2013Assignee: Medical Diagnostic Laboratories, LLCInventors: Jason Trama, Eli Mordechai, Martin E.

Patent number: 8394984Abstract: Recovery of an ethyl acetate solvent, optionally with the recovery of ethanol, from a crude product obtained from the hydrogenation of acetic acid. Separation and purification processes of the crude product are employed to allow recovery of the ethyl acetate solvent.Type: GrantFiled: July 9, 2010Date of Patent: March 12, 2013Assignee: Celanese International CorporationInventors: Victor J. Johnston, Lincoln Sarager, R. Jay Warner, Robert Cunningham, Trinity Horton, Radmila Jevtic

Patent number: 8394985Abstract: Recovery of an ester feed stream, optionally with the recovery of ethanol, from a crude ethanol product obtained from the hydrogenation of acetic acid. Separation and purification processes of the crude ethanol products are employed to allow recovery of the ester feed stream and for integration of the ester feed stream with an esters production process. The composition of the ester feed stream may vary, but at least comprises ethyl acetate and ethanol. The ester feed stream may be fed to one or more locations within the esters production process depending on the composition of the ester feed stream.Type: GrantFiled: July 9, 2010Date of Patent: March 12, 2013Assignee: Celanese International CorporationInventors: Victor J. Johnston, Lincoln Sarager, Alfonso Torres, R. Jay Warner, Josefina T. Chapman, Robert Cunningham, Trinity Horton, Radmila Jevtic
