Abstract
Abstract 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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
195 words
A flueric multiplier stage comprising: a first flueric device and a second flueric device, each said flueric device including a power nozzle for generation of a power stream, a left control port and a right control port, and receiver means adapted for a recovery of pressure from said power stream in proportion to the difference between the pressures applied to said control ports; a first conduit connecting the power nozzle of said first device to a first external pressure source; a second conduit connecting the power nozzle of said second device to a second external pressure source; the pressure differential between said first and second conduits providing one input to The multiplier stage; a third conduit interconnecting said left control ports with a third pressure source; and a fourth conduit interconnecting said right control ports with a fourth pressure source, the pressure differential between said third and fourth conduits providing a second input to the multiplier stage; whereby the pressure differential between corresponding elements of said receiver means will be a multiple of the product of the pressure differential between said first and second conduits and the pressure differential between said third and fourth conduits.
Claim 2
Dependent Claim
195 words
A flueric multiplier stage comprising: a first flueric device and a second flueric device, each said flueric device including a power nozzle for generation of a power stream, a left control port and a right control port, and receiver means adapted for a recovery of pressure from said power stream in proportion to the difference between the pressures applied to said control ports; a first conduit connecting the power nozzle of said first device to a first external pressure source; a second conduit connecting the power nozzle of said second device to a second external pressure source; the pressure differential between said first and second conduits providing one input to The multiplier stage; a third conduit interconnecting said left control ports with a third pressure source; and a fourth conduit interconnecting said right control ports with a fourth pressure source, the pressure differential between said third and fourth conduits providing a second input to the multiplier stage; whereby the pressure differential between corresponding elements of said receiver means will be a multiple of the product of the pressure differential between said first and second conduits and the pressure differential between said third and fourth conduits.
Claim 3
Dependent Claim
22 words
The flueric multiplier stage recited in claim 1 wherein said receiver means are symmetrically disposed with respect to the power nozzle axis.
Claim 4
Dependent Claim
51 words
The flueric multiplier stage of claim 2 wherein the said receiver means is disposed with respect to the power stream axis to provide pressure recovery in said receiver means which will continuously vary from zero to a finite value as control port pressure differential varies from zero to a finite value.
Claim 5
Dependent Claim
103 words
The flueric multiplier stage of claim 3 wherein each flueric device includes a left receiver and a right receiver respectively disposed on opposite sides of the power nozzle axis whereby the pressure differential between said right receivers will be a multiple of the product of the pressure differential between said first and second conduits and the pressure differential between said third and fourth conduits when the pressure in said third conduit exceeds that in said fourth conduit, and the pressure differential between said left receivers will represent the same product when the pressure in said fourth conduit exceeds that in said third conduit.
Claim 6
Dependent Claim
124 words
The flueric multiplier stage of claim 2 wherein each flueric device includes a left receiver and a right receiver oppositely disposed with respect to the axis of the power nozzle, and wherein is added a conduit connecting the left receive of said first device with the right receiver of said second device and a conduit connecting the right receiver of said first device with the left receiver of said second device whereby there is provided a push-pull circuit in which the pressure differential between the said right receivers and the pressure differential between the said left receivers is a constant multiple of the product of the differential pressure between said first and second conduits and the differential pressure between said third and fourth conduits.
Claim 7
Dependent Claim
73 words
The flueric multiplier stage of claim 5 wherein the said third conduit is connected with one of said first and second conduits, and the said fourth conduit is connected with the other of said first and second conduits whereby the pressure differential between the said right receivers and the pressure differential between the said left receivers is a multiple of the square of the differential pressure between the said first and second conduits.
Claim 8
Dependent Claim
65 words
The flueric multiplier stage of claim 5 in combination with a second said flueric multiplier stage wherein the first conduit of said second stage is interconnected with one of the receivers of one of said flueric devices in the first stage and the second conduit of said second stage is interconnected with the correspondingly located receiver in the other of said first stage flueric devices.
Claim 9
Dependent Claim
32 words
The combination of claim 7 wherein the third and fourth conduits of said second stage are commonly connected with the third and fourth conduits of the first stage to respective pressure sources.
