Patent number: 6523928Abstract: A method for treating a substrate is disclosed in which a propellant stream is passed through a channel and directed toward a substrate. Substrate pre-marking or post-marking treatment material is controllably introduced into the propellant stream and imparted with sufficient kinetic energy thereby to be made incident upon a substrate. A multiplicity of channels for directing the propellant and treatment material allow for high throughput, high resolution in-situ treatment. Marking materials and treatment materials may be introduced into the channel and mixed therein prior to being made incident on the substrate, or mixed or superimposed on the substrate without registration. One example is a single-pass, full-color printer.Type: GrantFiled: September 30, 1998Date of Patent: February 25, 2003Assignee: Xerox CorporationInventors: Eric Peeters, Jaan Noolandi, Raj B.

Patent number: 6455219Abstract: A process for making silica-containing latex particles involves polymerizing monomer in an emulsion comprising the monomer, water, silica particles, and optionally at least one surfactant, by adding at least one free radical initiator to the emulsion to form the silica-containing latex particles. In a preferred method, semicontinuous polymerization employing a seed latex is used to form the latex resin. The process achieves a silica-containing latex in which the silica is chemically incorporated therein that is ideally suited for use in the manufacture of toner and developer for xerographic use.Type: GrantFiled: June 22, 2001Date of Patent: September 24, 2002Assignee: Xerox CorporationInventors: Allan K.
