<p>1,187,685. Fluidic devices. HONEYWELL Inc. 1 Aug., 1968 [15 Aug., 1967], No. 36687/68. Heading G4P. A fluidic switching signal generator comprises a proportional amplifier 11 fed from power source 17 with pressure differential control signals applied over lines 19, 20 and outputs over lines 23, 30 to the respective first and second control inputs of identical proportional fluidic amplifiers 22, 29 fed from power source 34 with the second output of amplifier 22 connected for positive feedback to the first input of amplifier 29 and the first output of the latter similarly connected to the second input of amplifier 22. The first output of the latter and the second output of the former are connected to the respective inputs of bi-stable fluidic amplifier 40 fed from power source 46, and normally an output pressure signal appears at outlet 50, while application of a small differential pressure between lines 19, 20 transfers it to outlet 51. Amplifier 11 may be removed and the differential pressure control signals applied between lines 23, 30.</p> |
