  • Processes for aggregating toner components
    Patent number: 7572567
    Abstract: Processes for preparing toner compositions used with electrostatographic imaging members. The processes utilize screw extruders to facilitate continuous dispersion and aggregation of toner components, such as color pigments and wax. The continuous dispersion produces the toner components with more control and better product yield. The products produced are also improved in quality.
    Type: Grant
    Filed: November 21, 2006
    Date of Patent: August 11, 2009
    Assignee: Xerox Corporation

  • Power transfer unit
    Patent number: 7127967
    Abstract: A motor vehicle power transfer unit for distributing torque from a transmission assembly between a front wheel drive line and rear wheel drive line. The power transfer unit includes a housing that encloses a parallel gear set and a non-parallel gear set, which are coupled between an input portion and an output portion of the power transfer unit. The parallel gear set includes a driving gear, and idler gear and a driven gear and the idler gear is rotatably supported on a non-rotating support member that extends through the idler gear. Constructed in this manner, reduced lateral compactness of the power transfer unit is achieved.
