Abstract: A modular toy construction system is provided, comprising modular toy construction elements having either first connectors or second connectors, connectable to the first connectors. The system includes a worm drive element with an elongate body with a longitudinal axis and a length that is a discrete multiple of a fixed modular distance. A helical track is formed along the longitudinal axis of the elongate body. The system further includes a guide element with a body having a length, width, and longitudinal direction. A worm bearing is formed in the body of the guide element, and a track guide member is formed on a concave surface of the worm bearing. The track guide member is configured for cooperating with the helical track of the worm drive element. The helical track has a pitch of one turn for each four fixed modular distance of the length of the worm drive element.

Abstract: Processes for preparing toner compositions used with electrostatographic imaging members. The processes utilize screw extruders to facilitate continuous dispersion and aggregation of toner components, such as color pigments and wax. The continuous dispersion produces the toner components with more control and better product yield. The products produced are also improved in quality.

Abstract: Toner particles are prepared by a process comprising providing an extrusion apparatus; adding resin particles and additive particles to a supply means in the extrusion apparatus; adding the resin particles and the additive particles to a blending chamber in the extrusion apparatus, which blending chamber is maintained at a temperature of from about 50° C. to about 120° C.; blending the resin particles and the additive particles to form a mixture; extruding the resin particles to form extruded material; injecting liquid substances, which have a lower boiling point than the melt temperature of the resin particles, into the blending chamber during extrusion without the application of a vacuum to remove the liquid substances prior to extrusion; and grinding the extruded material to form toner particles.
