  • Patent number: 8801157
    Abstract: A liquid ink transport assembly mitigates the migration of ink dye from one conduit in a plurality of conduits to another conduit in the plurality of conduits. The liquid ink transport assembly includes a plurality of conduits, each conduit in the plurality having a first end and a second end, the conduits in the plurality being arranged in a parallel configuration with at least one conduit being spatially separated from an adjacent conduit by a first distance that is greater than a second distance spatially separating other conduits in the plurality of conduits, and a heater, the plurality of conduits being positioned proximate to a first side of the heater to enable the heater to heat ink being carried between the first and the second ends of the plurality of conduits.

  • Patent number: 7241559
    Abstract: A lens array and a method for fabricating the lens array are described herein. The lens array is made from a photosensitive glass plate containing a relatively small amount of a photosensitive agent (e.g., silver, gold or combination thereof) such that when the photosensitive glass plate is subjected to an exposure step, a heat treatment step and an optional ion exchange step it becomes a glass composite plate that includes glass regions which are lenses and also includes an opaque opal region located around each of the lenses. The lens array has clear, colorless lenses exhibiting greater sag heights than those yellow lenses found in a traditional lens array made from the traditional photosensitive glass plate which was subjected to similar exposure, heat treatment and ion exchange steps.
