Abstract: A mixing assembly includes a mixing basin, first and second pluralities of mixing paddles, and at least one motor. The mixing basin includes first and second parallel shafts extending therethrough. Each of the first and second pluralities of mixing paddles are positioned in an interior of the mixing basin. Each paddle of the first plurality of mixing paddles is coupled with the first shaft and configured to rotate about a first axis and each paddle of the second plurality of mixing paddles is coupled with the second shaft and configured to counter-rotate about a second axis. The counter-rotating mixing paddles are spaced apart to define a shear gap therebetween, and the motor is operable to drive the counter-rotation of the mixing paddles.

Abstract: Controllably conductive polymer compositions may be used in electrophotographic imaging developing systems, such as scavengeless or hybrid scavengeless systems or liquid image development systems. The conductive polymer compositions includes a charge-transporting material (particularly a charge-transporting, thiophene-containing polymer or an inert elastomeric polymer, such as a butadiene- or isoprene-based copolymer or an aromatic polyether-based polyurethane elastomer, that additionally comprises charge transport molecules) and a dopant capable of accepting electrons from the charge-transporting material. The invention also relates to an electrophotographic printing machine, a developing apparatus, and a coated transport member, an intermediate transfer belt, and a hybrid compliant photoreceptor comprising a composition of the invention.

Abstract: An apparatus for determining charge density and mobility in a liquid solution having electrically charged particles therein. The apparatus includes an electrode, and a dielectric member having a first surface situated opposite the electrode for providing a volume therebetween in which a sample of the liquid may be placed. A fixed bias voltage applied to the electrode to produce an electrical current flow through the liquid solution and the dielectric member. A device coupled to the dielectric member, measures the electrical current as a function of time to provide a measure of voltage decay across the liquid solution. The voltage decay corresponds to the charge density of the liquid solution.
