Patent number: 8685607Abstract: The continuous process for manufacturing toners disclosed herein includes continuously feeding components of a toner composition into a feed section of a screw extruder at a controlled rate. The continuous process for manufacturing toners may include feeding the components of a toner composition into the feed section of a screw extruder without performing an external or secondary dispersion step. That is to say, the components of the toner composition may be fed directly into the extruder without using dispersions of individual components as used in batch processes. Rather, the toner components are added to the extruder in dry form, melt-mixed, and may be dispersed in aqueous form in the extruder. The process may produce micron-sized toner particles, thus no further size reduction may be necessary.Type: GrantFiled: August 29, 2012Date of Patent: April 1, 2014Assignee: Xerox CorporationInventors: Joo T. Chung, Chieh-Min Cheng, Zhen Lai, Mark E. Mang, Eugene F. Young, Brian Andaya, Joseph Leonardo

Patent number: 8557566Abstract: An optical instrument monitors PCR replication of DNA in a reaction apparatus having a temperature cycled block with vials of reaction ingredients including dye that fluoresces in presence of double-stranded DNA. A beam splitter passes an excitation beam to the vials to fluoresce the dye. An emission beam from the dye is passed by the beam splitter to a CCD detector from which a processor computes DNA concentration. A reference strip with a plurality of reference emitters emit reference beams of different intensity, from which the processor selects an optimum emitter for compensating for drift. Exposure time is automatically adjusted for keeping within optimum dynamic ranges of the CCD and processor. A module of the beam splitter and associated optical filters is associated with selected dye, and is replaceable for different dyes.Type: GrantFiled: January 17, 2006Date of Patent: October 15, 2013Assignee: Applied Biosystems, LLCInventors: Michael R. Gambini, Eugene F. Young, Edward J. Lakatos, Anthony L. Cerrone, Susan Atwood Stone, Judith K. Atwood
