  • Maintenance modules for fluid jet device
    Patent number: 6935721
    Abstract: A maintenance module for a fluid jet device includes a first plate and a second plate affixed to the first plate. The first and second plates each define a longitudinal axis and a transverse axis perpendicular to the longitudinal axis. The first plate has a plurality of orifices formed therein extending parallel to the longitudinal axis inwardly of longitudinal edges. The first plate includes a vacuum opening formed therein at about a transverse edge of the first plate. The vacuum opening is formed perpendicular to a plane defined by the longitudinal and transverse axes. The second plate has an elongated channel extending over the first plate orifices so that the orifices are exposed through the channel. The channel is defined by opposing longitudinal edges extending parallel to the longitudinal axis. The channel has tapered edges at about an end thereof that converge to an arcuate funneling region.

  • Adapter and mating bottle cap for coupling bottles to ink supplies
    Patent number: 6164768
    Abstract: An ink supply system comprises an adapter, mounted upon the ink supply reservoir, and a mating bottle cap, secured to the ink supply container, for coupling the ink supply container to the ink supply reservoir adapter, wherein both the ink supply reservoir adapter and the ink supply container cap have unique mating or corresponding polarizing structure fixedly or integrally mounted thereon such that the ink supply reservoir will only accept such uniquely predeterminedly configured or structured ink supply containers. In this manner, non-compatible or inferior quality ink materials are not introduced into the ink supply reservoir.
