    Abstract: Material is added to a liquid jet to reduce jet dissipation by increasing the characteristic viscosity and surface tension of the liquid. Specifically, polyethylene oxide is added to water to increase the surface tension and apparent characteristic viscosity of water to decrease the dispersive effect of air on a water or liquid stream issued from a high velocity nozzle.

    Abstract: Techniques are disclosed whereby the output signal versus input signal characteristic of a fluidic circuit is varied in response to changes in a predetermined parameter of the input signal. In various embodiments disclosed the input signal parameter of interest is the average amplitude, magnitude of amplitude fluctuations with respect to average amplitude, frequency of amplitude fluctuations from average amplitude, average magnitude of fluctuations from average amplitude, average frequency of amplitude fluctuations from average amplitude, first or higher order derivatives with respect to time of the input signal amplitude, phase, amplitude or frequency, frequency difference between two input signals, difference between derivatives with respect to time of amplitude, frequency or phase of two or more input signals, or any combination of the above.
