Abstract: A method of printing onto closed vial units. The vial units are formed in a series and the vial units have a drug therein. The method involves providing the series of vial units onto a conveyor belt; positioning the vial units adjacent cleats on the conveyor belt; engaging a first offset inking transfer device on a fist side of said vial units; engaging a first back-up roller against said vial units, said first back-up roller being placed opposite said first offset inking transfer device; capturing the vial units between said first back-up roller and said first offset inking transfer device; printing onto the vial units with said first offset inking transfer device; and curing the ink with a first ultra violet dryer.

Abstract: An apparatus for molding a proppant is disclosed. The apparatus comprises a first member comprising a manifold for channeling a plastic fluid to a cavity block, with the cavity block containing a plurality of semi-spherical cavities. The apparatus further includes a second member that comprises a movable plate for engaging with the first member, with the movable plate having an opening therein, and a core block positioned within the opening, with the core block containing a plurality of reciprocal semi-spherical cavities configured to engage the semi-spherical cavities of the cavity block so that a plurality of spheres are formed, with the core block further containing a plurality of arm cavities that link the plurality of spheres so that a star cluster (which links the proppants) is formed. A method of manufacturing proppants and a method of using the proppants is also disclosed.

Abstract: An apparatus for printing onto closed vial units. The vial units are formed in a series and the vial units have a drug therein. The apparatus comprises a conveyor belt for moving the vial units, with the conveyor belt having spaced cleats. A first side of the vial units is placed on the conveyor belt. The apparatus further comprises a printhead for printing an ink pattern onto the vial units, with the printhead configured to print to the first side, and a back-up roller configured opposite the printhead, with the back-up roller being a cylindrical member that contains an indented profile placed about the cylindrical member reciprocal to the vial units. The apparatus further includes a dryer positioned to receive the vial units from the printhead and provide for drying of the ink pattern from the printhead.
