ABSTRACT:
A jet drop recorder produces a continuously flowing stream of recording liquid and has a pair of deflection electrodes positioned therealongside but offset therefrom. The stream of recording liquid is stimulated to break up into uniformly sized and regularly spaced drops, and the electrodes are positioned such that at least portions thereof are upstream from the break-off point. Drops produced by the stream are steered to different laterally separated printing positions by application of a cyclic differential charging signal to the electrodes. This causes a stepped cyclic deflection of the unbroken stream, which in turn directs the drops toward the desired printing positions. There is no need to provide a drop deflection field. Furthermore the filament need not have any particular level of conductivity, as the disclosed electrode configuration produces a gradient electrical field capable of polarizing and deflecting a perfectly dielectric liquid.
A selective drop catching technique is employed in combination with the above mentioned lateral steering. Such catching is accomplished by means of a cooperative charging signal applied simultaneously to the deflection electrodes. This cooperative charging signal causes the unbroken stream to be deflected in a dumping direction perpendicular to the above mentioned direction of lateral deflection. A catcher is positioned for catching of those drops deflected in the dumping direction. A large number of such jet drop recording devices may be arranged in two parallel rows.
