Abstract

1375672 Fluidic control circuits JOHNSON SERVICE CO 25 Jan 1972 [25 Jan 1971] 23158/74 Divided out of 1375671 Heading F1P In the fluid temperature control circuit shown, a flow resistance 164 senses changes in viscosity of a fluid due to changes in temperature and controls the steam emitted by a nozzle 162 of a summing impact modulator 157. The output of the latter is connected to a diaphram amplifier 166 which produces the desired controlling or signal transmitting pressure which may be fed through a relay 167 to an output line 168. Negative feedback to a nozzle 158 is provided through a resistance 169.
