  • Patent number: 10744754
    Abstract: Ink-based digital printing systems useful for ink printing include a photoreceptor layer configured to receive a layer of liquid immersion fluid. The liquid immersion fluid includes dampening fluid, dispersed gas particles, and charge directors that impart charge to the solid particles. The photoreceptor surface is charged to a uniform potential, and selectively discharged using an ROS according to image data to form an electrostatic latent image. The charged liquid immersion fluid adheres to portions of the photoreceptor surface according to the electrostatic latent image to form a fountain solution image. The fluid portion of the fountain solution image can be partially transferred to an imaging member and/or transfer member to form a dampening fluid image, either or both of which may be electrically biased. The dampening fluid image is inked on the transfer member, and the resulting ink image transferred to a print substrate.

  • Publication number: 20200156387
    Abstract: Disclosed are a substrate package, a method of fabricating the substrate package, and a system including the substrate package. The substrate package includes a stack of substrate sheets in an individual form, a continuous form, or a roll form. The stack has a sidewall defined by edges of the substrate sheets and a mark on the sidewall includes mark segments on respective edges. The mark segments vary such that one or more of the mark segments have a respective segment characteristic, such as a length. The segment characteristic can encode information about an attribute of the substrate sheet, such as a physical characteristic of the sheet.

  • Patent number: 8308281
    Abstract: An ink umbilical provides different colors of heated ink to multiple print heads in an integrated structure. The ink umbilical includes a first plurality of ink carrying conduits mounted on one side of a heater and a second plurality of conduits mounted on a second side of the heater opposite the first side of the heater. The heater is operated to keep the ink in the conduits on each of the heater in a predetermined temperature range.

  • Patent number: 5709181
    Abstract: A rocker arm and hydraulic lash adjuster assembly is disclosed. The assembly includes a shaft mounted rocker arm having a valve actuating arm portion which includes a stepped bore for slidingly receiving a hydraulic element. The bore has an open end, a cylindrical wall and a closed end having a spot face formed therein, and fluidly connected via a passage in the rocker arm to a source of pressurized fluid. The stepped bore is configured to receive a flat wear plate in abutment with the closed end and the hydraulic element such that the wear plate and the hydraulic element cooperate to define a fluid reservoir therebetween for pressurized fluid. The wear plate includes a centrally located through-bore operable to fluidly connect the fluid reservoir and the spot face formed integrally with the closed end of the stepped bore to define a passage from the source of pressurized fluid to the fluid reservoir to thereby fill the hydraulic element with pressurized fluid.

  • Patent number: 5706771
    Abstract: A valve actuation assembly for an internal combustion engine is disclosed in which a rotatable rocker arm assembly is actuated by an engine driven camshaft to move a poppet valve reciprocably. The rocker arm assembly includes a hydraulic lash adjuster for disposition between the rocker arm and the valve stem. The lash adjuster includes an actuator at one end having an axially extending neck which terminates in an enlarged head. The enlarged head engages a foot assembly which includes a disk having a socket in which the head is positioned. A retainer ring is disposed in the socket and includes a wall portion which operates to establish an interference fit with the socket so as to fix the ring in the socket and a radially inwardly extending flange member which operates to define an opening through which the actuator neck extends but having a diameter less than that of the enlarged head portion of the actuator to thereby prevent removal of the head from the socket.
