Scott Silence 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).

  • Patent number: 8278018
    Abstract: In accordance with the invention, there is a method of forming a toner. The method can include blending two or more colorants to form a sample toner and forming a sample color specimen including a printed image comprising the sample toner. The method can further include comparing spectral distribution curves of the sample color specimen with that of a target color specimen including a target color and repeating the disclosed steps until acquiring a desired spectral match between the sample toner and the target color.
    Type: Grant
    Filed: March 14, 2007
    Date of Patent: October 2, 2012

  • Publication number: 20060222993
    Abstract: Particles, preferably toner particles comprised of at least binder and colorant, are described that include a doped conductive polymer material as a surface additive on the external surface of the particle. The presence of the doped external conductive polymer material enables the particles to retain a substantially uniform charge distribution over the surface of the particles over time, and also enables appropriate control over the triboelectric (tribo) properties of a developer. Also described are developers comprised of such particles in admixture with carrier particles, and methods of making the particles and developers.

  • Publication number: 20060177242
    Abstract: Super wire history image defects in an image development system including one or more electrode wires disposed in a gap between a toner donor roll and an imaging member are reduced by providing an initial toner composition in the image development system, the initial toner composition containing at least 30 number % fine particles having a particle size no greater than 5 ?m; and providing replenisher toner into the development system to replenish the toner used to produce images by the image development system; the replenisher toner containing 20 number % or less fine particles having a particle size no greater than 5 ?m.

  • Publication number: 20060121378
    Abstract: A process for preparing toner compositions using a dry pigment is provided. The process comprises combining a base toner resin composition, a dry pigment, and dispersion agent in a one step process, without the need any pre-processing of the pigments such as by, for example, flushing. The process includes combining the base toner resin, dry pigment and dispersion agent in a processing apparatus such as an extruder. The process may also comprise preparing the toners via an extrusion process utilizing a screw having a configuration designated herein as a Type C screw.

  • Publication number: 20060115758
    Abstract: A toner is disclosed that includes a binder and at least one colorant, wherein the binder includes an amorphous polyester material, a cross-linked polyester material, an optional embrittling agent material, and a crystalline polyester material. The toner may be mixed with a suitable carrier to form a developer.

  • Patent number: 6326118
    Abstract: A carrier and developer material for use in an electrostatographic imaging process comprises a metallic core material which has a diffusion-bonded surface alloy layer on the surface of the particle and an optional polymer layer overcoating the alloy layer. The carrier provides improved conductivity and triboelectric properties when used in an electrophotographic imaging process.
