摘要： A method for grinding colorant agglomerates with a grinding medium comprising a Group IIIB and/or a lanthanide element and a Group IVB oxide. The grinding medium has a grain size of less than about 1.35 microns, and results in the production of substantially pure colorant concentrates.

摘要： An ink-jet printer cartridge having a center reservoir chamber and two side reservoir chambers for holding inks of three different colors is provided with ink flow pathways of special configuration for connecting the reservoir chambers to exit ports at the print element. The ink flow pathways are provided with ridges extending along substantially their entire lengths so that air bubbles cannot completely block ink flow through the pathways. The ink flow pathways are disposed such that they have a vertical component of direction over their entire length and the pathways connecting the side reservoir chambers to exit ports include duct portions disposed at compound angles relative to the axes of the cartridge so that air bubbles, because of their buoyancy, will naturally tend to drift upwardly through the inclined ducts toward the reservoir chambers during normal usage, or drift toward the exit openings when the cartridge is inverted for priming. The duct portions of the ink flow pathways are generally trapezoidal in cross-section, the side walls intersecting the top wall at acute angles so that air bubbles cannot completely block the duct portions. The duct portions have end surfaces for directing air bubbles toward the reservoir chambers during priming, the end surfaces being end faces of plugs.
摘要翻译：具有中央储存室和用于保持三种不同颜色的油墨的两个侧储存室的喷墨打印机墨盒设置有用于将储存室连接到打印元件处的出口的特殊结构的墨流路。油墨流动路径设置有沿着其整个长度延伸的脊，使得气泡不能完全阻止通过路径的油墨流动。油墨流动通道被设置成使得它们在其整个长度上具有方向的垂直分量，并且将侧面储存室连接到出口的路径包括相对于盒的轴线以复合角度设置的管道部分，使得气泡因为它们的浮力自然会倾向于在正常使用期间向上倾斜通过倾斜的管道朝储存室移动，或者当墨盒倒置以便起泡时向着出口开口漂移。油墨流动通道的管道部分的横截面通常为梯形，侧壁以锐角与顶壁相交，使得气泡不能完全阻挡管道部分。导管部分具有用于在起动期间将气泡引向储存室的端面，端面是插塞的端面。

摘要： The invention is directed to an ink cartridge for use in printing an ink on a print medium with an electronic printer. The ink cartridge includes an ink disposed therein having a viscosity of between approximately 1.5 and 10 centipoise. An ink cartridge has an unfelted foam therein. The foam carries the ink and has a plurality of pores disposed substantially in communication with each other. The pores have an effective porosity of between approximately 60 and 90 pores per inch. The ink cartridge further has a printhead assembly disposed in fluid communication with the foam. The foam has an effective porosity, dependent on the viscosity of the ink, wherein ink is allowed to flow from the foam to the printhead assembly during periods of operation, and is substantially prevented from flowing from the printhead assembly during periods of inoperation.
摘要翻译：本发明涉及一种用于在具有电子打印机的打印介质上印刷墨水的墨盒。墨盒包括其中设置有约1.5至10厘泊之间的粘度的墨水。墨盒在其中具有未熔化的泡沫。泡沫体携带墨水并且具有基本上彼此连通设置的多个孔。孔隙具有约每英寸约60-90个孔的有效孔隙率。墨盒还具有设置成与泡沫流体连通的打印头组件。泡沫具有有效的孔隙度，取决于油墨的粘度，其中在操作期间允许油墨从泡沫流动到打印头组件，并且基本上防止在操作期间从打印头组件流出。

摘要： Pressure is applied to a resilient seal around the venting portion of a print head while the nozzles are elevated in the vertical position above the ink, thereby forcing ink out of the nozzles and purging the in-flow paths of air.
摘要翻译：当喷嘴在墨水上方的垂直位置升高时，将压力施加到打印头的通气部分周围的弹性密封件上，从而迫使墨水从喷嘴中排出并吹扫空气的流入路径。
