    • Ink additives that reduce the deceleration of inks containing a polymer, such as acrylate binders, are disclosed. In accordance with the invention, an ink-jet liquid, an ink-jet liquid set, and the method for using the same are provided, wherein the one of the liquids comprises an aqueous vehicle, and a deceleration-alleviating component. The present formulations are used to formulate ink-jet liquids, and more particularly, to provide enhanced drop ejection performance in inks containing a polymer, such as deceleration (rapid drop velocity degradation during continuous operation of the firing resistor), when the liquid contains a deceleration-alleviating agent, such as, an aromatic glycol ether, a polar solvent and a long alkyl chain surfactant.
    • 公开了减少含有聚合物如丙烯酸酯粘合剂的油墨的减速性的油墨添加剂。 根据本发明,提供一种喷墨液,喷墨液体组合物及其使用方法,其中一种液体包括水性载体和减速缓解组分。 本发明的配方用于配制喷墨液体,更具体地说,为了在含有聚合物的油墨中提供增强的液滴喷射性能,例如减速(在连续操作燃烧电阻器时的快速下降速度降低),当液体含有 减速缓释剂,如芳族二醇醚,极性溶剂和长烷基链表面活性剂。

    • Liquid (13, 13a) within a vessel (12, 12a) which receives an inflow is maintained at a predetermined level (43) by discharging liquid as necessary to compensate for the inflow. Discharge flow is drawn from below the surface (18) of the liquid to avoid clogging from scum or from other undesirable effects of surface draw off. Intake structure (34) for the discharge pump (33, 33a) has a branched flow path (47) that includes a first inlet (48) situated above the predetermined level, a second inlet (49) situated below the predetermined level and a flow junction (51) through which both inlets are communicated with the discharge pump, the junction being at the predetermined liquid level. If the liquid rises above the flow junction, the pump draws liquid through the second, subsurface inlet. If the liquid surface recedes below the flow junction, the pump aspirates air or other gas through the first inlet. Consequently liquid level is stabilized at the elevation of the flow junction. The system is applicable, for example, to chemostats (11, 11a) in which microorganisms are cultured in a liquid medium.
    • 接收流入的容器(12,12a)内的液体(13,13a)通过根据需要排出液体而保持在预定水平(43)以补偿流入。 从液体的表面(18)的下方抽出排出流,以避免从浮渣或其他不希望的表面抽出的影响堵塞。 用于排放泵(33,33a)的进气结构(34)具有分支流路(47),其包括位于预定水平高度的第一入口(48),位于预定水平以下的第二入口(49) 接头(51),两个入口与排放泵连通,该接合处于预定液位。 如果液体在流动接头上方升起,泵将液体通过第二个次表面的入口吸入。 如果液面低于流动接头,泵将吸入空气或其他气体通过第一个入口。 因此,液位在流动接头的高度处稳定。 该系统适用于例如在液体培养基中培养微生物的恒化器(11,11a)。
