Patents by Inventor Simon C. Burke

Simon C. Burke has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20150212446
    Abstract: There is described an a bias charge roller including an electrically conductive core and an outer layer axially supported on the core. The outer layer includes a continuous raised pattern above a non-contact surface wherein the continuous raised pattern includes a contact surface having a height of from about 10 microns to about 40 microns above the non-contact surface. The outer layer transitions from the contact surface to the non-contact surface over a minimum linear distance of 100 microns or greater. The contact surface is configured to contact a charge-retentive surface of an electrophotographic imaging member so as to charge the charge-retentive surface.
    Type: Application

  • Patent number: 8663565
    Abstract: A continuous emulsion aggregation process for the production of particles is presented including a plurality of continuous stirred-tank reactors (CSTR). The plurality of continuous stirred-tank reactors includes at least one feed tank of raw materials, at least one reactor for facilitating cold addition, at least two reactors for facilitating an aggregation process, at least one reactor for facilitating a shell addition process; at least one reactor for facilitating a freeze process, at least one reactor for facilitating a chelating process, at least one reactor for facilitating a ramp-up process and at least one reactor for facilitating a coalescence process, wherein the reactors are sequentially assembled in a series configuration and separated by short conduits to produce toner particles that are narrowly distributed.
