摘要： Imaging apparatus for duplex printing on a substrate having first and second sides and a leading edge and a trailing edge, the imaging apparatus including a first member having an image support surface adapted to sequentially support first and second images thereon, a second member adapted to support the substrate such that one side of the substrate engages the image support surface, leading edge first, at a transfer region and transfer apparatus for transferring the first image from the image support surface to the first side of the substrate at the transfer region while at least partially fixing the image thereto. The imaging apparatus also includes a waiting station adjacent the second member for receiving the substrate after transfer of the first image thereto and prior to the transfer of the second image thereto and an output station for receiving the substrate after completion of image transfer thereto. The imaging apparatus includes deflector apparatus adjacent the second member operative to receive the substrate directly from the second member and selectably deflect the substrate towards the waiting station or the output station for delivery thereto and roller apparatus associated with the waiting station for selectably engaging the trailing edge of the substrate after the substrate has been delivered to the waiting station for delivering the substrate back to the second member. The second member is operative to deliver the substrate to the transfer region, whereat the second image is transferred to the second side of the substrate.

摘要： A liquid composition for developing latent electrostatic images comprising toner particles associated with a pigment dispersed in a nonpolar liquid. The salient feature of the invention is that the toner particles are formed with a plurality of fibers or tendrils from a thermoplastic polymer and carry a charge of a polarity opposite to the polarity of the latent electrostatic image. The polymer is insoluble or insolvatable in the dispersant liquid at room temperature. The toner particles are formed by plasticizing the polymer and pigment at elevated temperature and then either permitting a sponge to form and wet-grinding pieces of the sponge or diluting the plasticized polymer-pigment while cooling and constantly stirring to prevent the forming of a sponge while cooling. When cool, the diluted composition will have a concentration of toner particles formed with a plurality of fibers.

摘要： A method for providing an image on either opaque or transparent substrates (42) to have substantially equal apparent color saturation when viewed and including the steps of: developing a latent electrostatic image on an image bearing surface (16) using a colored liquid developer in a developer system operating at given voltages; and subsequently transferring the image to the substrate (42) wherein said liquid developer, developer system and voltages are the same for printing on both opaque and transparent substrates. The method utilizes a control apparatus, operative when the substrate (42) sought to be printed is transparent, for causing each toner image to be developed on an image bearing surface (16) and transferred to an intermediate transfer member (40) a plurality of times, before the image is transferred therefrom to the transparency, and when the substrate (42) sought to be printed in opaque, for causing each toner image to be developed on the image bearing surface (16) and transferred to the intermediate transfer member (40) only once, before the image is transferred therefrom to the opaque substrate.

摘要： A filter for separating a flowing fluid containing charged particles into two streams, one essentially free of particles and one laden with particles, includes a main conduit having an inlet at one end for receiving the flowing fluid, and having two outlets downstream of the one end for dividing the flow into two outlet flow paths. A pair of electrodes between which the fluid flows, is located in the main conduit upstream of the outlets; and each of the outlets is associated with a respective electrode. Voltage sources are connected to the electrodes such that one is more positive than the other for establishing, in the fluid flowing between the electrodes, an electric field transverse to the direction of flow whereby the particles in the field are attracted toward one of the electrodes and travel into the outlet associated therewith. A dielectric coating of release material in the form of a fluorosilicone polymer is applied to the surface of the one electrode for inhibiting plating-out of particles thereon while fluid flows in the conduit.
