  • Patent number: 9250571
    Abstract: An approach is provided for filling a toner container useful in printing. The approach involves causing, at least in part, a toner container to be coupled to a base member, the base member being configured to contact a lift mechanism. The approach further involves causing, at least in part, the toner container to be moved to a filling position by the lift mechanism. The approach also involves causing, at least in part, a predetermined amount of a toner to be input into the toner container by a filling process when the toner container is in the filling position. The approach additionally involves causing, at least in part, at least the toner inside the toner container to be agitated by way of the base member during the filling process, at least until the toner container is filled with the predetermined amount of toner.

  • Patent number: 8608367
    Abstract: A screw extruder is presented including a feed hopper for receiving materials and a body member having at least one supply port and at least one outlet port. The screw extruder also includes a screw positioned within the body member and movable along a channel defining a longitudinal axis. The screw extruder further includes a drive shaft for rotatably driving the screw along the channel. The screw extruder may be configured to mix the materials received via the feed hopper with a series of one or more forward, neutral, and reverse kneading elements.

  • Patent number: 8563627
    Abstract: A process for making a self-emulsifying granule suitable for use in forming latex emulsions includes contacting a resin with a solid or highly concentrated surfactant, a solid neutralization agent and water in the absence of an organic solvent to form a mixture, melt mixing the mixture, and forming self-emulsifying granules of the melt mixed mixture. Self-emulsifying granules are also provided and configured to form a latex emulsion when added to water, which may then be utilized to form a toner.

  • Patent number: 8328051
    Abstract: Disclosed are embodiments of a powder filler system incorporating a pair of symmetrical agitators within a hopper, containing powder and having an upper cylindrical portion and a lower funnel portion. Each agitator includes: a first bar extending from the top of the hopper to a tubular section of the funnel portion; a second bar connected to the first bar and extending towards an interface between the upper cylindrical and lower funnel portions of the hopper; a third bar connected to both the first and second bars such that it is approximately parallel to an angled sidewall of a conical section of the funnel portion; and vertically oriented and angled fins connected between the second and third bars. Agitators configured in this manner maintain the powder at an essentially uniform density within the hopper; move the powder towards the auger such that cavitations/starvations are avoided; and ensure a steady discharge flow.
