    摘要： A fluid system wherein diverse fluids are injected into a small diameter line such that when their relative positions are thereafter sensed they can be used in data processing operations. The injected fluids are thus used for memory, correspondence, control, and measurement purposes.

    摘要： The subject fluidic oscillator means includes a pair of bistable amplifiers having feedback control lines selected and connected in a manner to render the resulting device relatively insensitive to variations in the fluid pressure supply. The control signal ports of each amplifier are connected with the output ports of the other amplifier by conductors of predetermined differential length-to-area and volume ratios so selected and combined as to counteract the effects of supply pressure change, thus securing the above-mentioned result.

    摘要： A fluidic sensing and processing system monitors the enthalpy and/or sensible heat of an outside air and of return air to select the air placing the minimum load on a mechanical refrigeration apparatus. Fluid pressure signals correctponding to the dry-bulb temperature of the air and to the relative humidity of the air are created and summated in a resistor network including individual fluidic summing resistors connected to a common summing point. The summing resistors are directly interrelated with a particular ratio producing a constant output pressure with constant enthalpy but with varying temperatures and humidity. The common psychrometric chart may be employed to indicate the area over which a particular resistance ratio will produce a predictable and reliably significant correlated output pressure. The pair of sensing networks provide output related to the relative enthalpy of the return air and the outdoor air. The output of the networks are connected to a fluidic comparator to establish a selection signal connecting the return air or outside air to the mechanical refrigeration unit. An overriding temperature control comparison is further introduced to provide an overriding control in accordance with the relative outside air temperature with respect to the temperature of the return air from the conditioned zones. If the outside air dew point is below the discharge temperature, air from either source will pass through the mechanical refrigeration without condensation of moisture and selected air should be that with the lowest sensible heat regardless of its enthalpy. The two resistor networks may be applied to a fluidic amplifying device such as a summing impact modulator to produce a proportional output which continuously adjusts the mixture of the two air sources to produce air with a constant enthalpy.

    摘要： A flueric multiplier stage is disclosed which comprises two fluid amplifiers whose power streams are respectively connected to opposite sides of a first pressure differential signal and whose control ports are connected in parallel across a second pressure differential signal. The output receivers of the fluid amplifiers are cross-connected such that the left receiver of the first amplifier is connected to the right receiver of the second amplifier, the structure described being adapted to provide a push-pull output signal which is proportional to the product of two push-pull input signals. Circuits incorporating the basic multiplier stage are also disclosed, as are circuits in which the output is restricted to respond to a singularly directional input.
