  • Patent number: 6972304
    Abstract: Disclosed is an aqueous ink composition comprising an aqueous liquid vehicle, a colorant, and an additive wherein, when the ink has been applied to a recording substrate in an image pattern and a substantial amount of the aqueous liquid vehicle has either evaporated from the ink image, hydrogen bonds of sufficient strength exist between the additive molecules so that the additive forms hydrogen-bonded oligomers or polymers.

  • Patent number: 6871945
    Abstract: A process comprising incorporating into an ink jet printing apparatus a developing composition; an oxidizing composition a coloring composition; and a fixing composition; ejecting droplets of the developing composition onto the substrate; ejecting droplets of the oxidizing composition onto the substrate; ejecting droplets of the coloring composition onto the substrate; and ejecting droplets of the fixing composition onto the substrate; wherein the process results in at least some portions of the substrate bearing images comprising all four compositions, the portions forming a printed image. Specific embodiments are directed to the realization of continuous tone and gray scale in image by control of the time at which color forming reactions are quenched by controlling the lime period between deposition of the color forming liquids and deposition of the fixing liquid; or control of the extent of color forming reactions by limitation of the quantity of one of the color forming liquids.

  • Patent number: 6726546
    Abstract: A method and apparatus for deburring nonmetallic machined workpieces. A deburring material of sufficient hardness to debur nonmetallic workpieces without causing scarring thereto is rubbed against a workpiece to effect deburring. The deburring material has a durometer hardness and consequently a coefficient of friction whereby frictional engagement of a burr with the deburring material is stronger than the attachment of the burr to the workpiece and therefore the burr is removed as the deburring material is actuated and brought into contact with the burr. The deburring material can be, e.g., polyisoprene and may be mechanically actuated or actuated by hand.
