Abstract: Droplets of a magnetic liquid are pulled from an outlet or orifice of a nozzle by applying a magnetic force to the magnetic liquid, which is under a relatively low static pressure, within the nozzle whereby the droplets, which are ink, impinge upon a recording surface. Each droplet is pulled from the outlet of the nozzle by applying a magnetic force adjacent the outlet, a magnetic force from the opposite side of the recording surface from the nozzle outlet, or magnetic forces from both sides of the recording surface.

Abstract: An ink jet recording system emits a stream of ink which is amplitude or frequency modulated to produce discrete droplets. A weir is located adjacent to the trajectory of the droplets, downstream from the jet orifice, and at a critical location near the point of drop formation where it contacts and deflects droplets of larger transverse diameter. Amplitude modulation yields ink drops of basically the same volume which break off before and after the weir, with those which break off earlier being deflected during an initial interval while they have a large transverse diameter. In frequency modulation the actual size of the drops and ultimate diameter are modulated. Such deflected droplets separate from the stream closer to the jet orifice. The deflected droplets are caught in a gutter.
Abstract translation: 喷墨记录系统发射一个幅度或频率调制以产生离散液滴的油墨流。 堰位于液滴的轨迹附近，位于喷射孔的下游，并且位于靠近液滴形成点的临界位置处，其接触和偏转较大横向直径的液滴。 幅度调制产生基本上相同体积的墨滴，在堰前后断裂，其中在初始间隔期间断裂的那些在初始间隔期间具有较大的横向直径。 在频率调制中，液滴的实际尺寸和最终直径被调制。 这种偏转的液滴与更接近喷射孔的流分离。 偏转的液滴被捕获在沟槽中。
