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.

Method and apparatus for filling a toner container useful in printing

A process for making a latex emulsion suitable for use in a toner composition includes contacting at least one polyester resin optionally with an organic solvent to form a resin mixture, adding a primary amine, optionally a surfactant, and deionized water to the mixture.

Processes for producing polyester latexes via solvent-based and solvent-free emulsification

Solvent-free bio-based emulsion

A process for making a latex emulsion suitable for use in a toner composition includes contacting at least one amorphous polyester resin with a viscosity reducing additive in the absence of an organic solvent to form a resin mixture either via an extruder or batch process, and adding a surfactant, neutralizing agent, and deionized water to the resin mixture.

Processes for producing polyester latexes via solvent-free emulsification

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.

Screw extruder for continuous and solvent-free resin emulsification

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.

Self emulsifying granules and process for the preparation of emulsions therefrom

Solvent-free extrusion processes are disclosed that are suitable for forming high bio-based polyester latexes that may be utilized in forming a toner, as well as other commercial products.

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.

Fine powder filler system

A process for making a self-emulsifying composite suitable for use in forming latex emulsions includes contacting a resin with a solid or highly concentrated surfactant, a solid neutralizing agent in the absence of water and an organic solvent to form a mixture, melt mixing the mixture, and forming a self-emulsifying composite of the melt mixed mixture such as a granule. 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.

Self emulsifying granules and solvent free process for the preparation of emulsions therefrom

A process for making a latex emulsion suitable for use in a toner composition includes contacting a resin with a solid neutralizing agent in the absence of an organic solvent to form a mixture either via a co-feeding process or a pre-blend mixture, and adding a solid or aqueous surfactant to the pre-blend mixture or prior to melt mixing the mixture.

The present invention relates to a method for high intensity blending of toner particles in order to cause additive materials to become firmly affixed to the surface of base toner particles. The method includes using a blending tool having a shank with riser members at each end, such risers being angled outward from the axis of the shank between 10 and 16 degrees and having regions toward the trailing edges that are thicker than regions near the leading edges.

Method of blending toners using a high intensity blending tool with shaped risers for decreased toner agglomeration

The present invention relates to a high intensity blending apparatus, particularly for blending operations designed to cause additive materials to become affixed to the surface of base particles. The tool comprises a shank having riser members at each end, such risers being angled to the axis of the shank between 10 and 16 degrees and having regions toward the trailing edges that are thicker than regions near the leading edges.

A jet mill includes plural nozzle devices for discharging a composite stream of high velocity fluid. Each nozzle device includes a plural odd number of nozzle openings for discharging an individual stream of high velocity fluid. Each nozzle opening comprises (i) a converging region for converging and accelerating a volume of high pressure fluid; (ii) a throat region defining a narrowest diameter region of the nozzle opening; (iii) a first expansion region for producing a linear expansion of the volume of high pressure fluid, and (iv) a second expansion region for producing a turning expansion as well as a parallel flow of the volume of high pressure fluid.
