Abstract:
1. An apparatus, comprising: a tube with an ingress opening to receive a liquid, and an egress opening to release the liquid; a conductor positioned in a conduit of the tube, the conductor and the conduit having dimensions to cause a surface tension of the liquid to prevent a constant flow of the liquid from the egress opening, wherein the conductor is a sleeve positioned in the tube, wherein a diameter of the sleeve results in one of the outer surface of the sleeve contacting the surface of the conduit, or the outer surface of the sleeve having a separation from the surface of the conduit of the tube; and a power supply coupled to the conductor to apply a charge to the liquid to overcome the surface tension and form at the egress opening a single jet stream of the liquid applicable on a substrate to create a pattern, wherein the single jet stream is controllable in part by a viscosity of the liquid.
