Abstract

1,137,348. Analogue-to-digital converters. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. 23 Oct., 1967 [26 Oct., 1966], No. 47970/66. Heading G4P. [Also in Divisions G1 and G3] Indicators 16, 17, 18 of particular speeds are operated by comparing the fluid pressure built up in a reservoir 12 in direct proportional relationship with the speed of a shaft 1 with different reference pressures applied to devices 13, 14, 15 (see Division G1) in each of which the pressure differential is amplified through a succession of fluid differential amplifying devices 19, 23, 25 and a bi-stable fluidic device 27. One output of each pair is fed back through a restricting valve 29 to the reference input amplifier 19 so that immediately the device 27 tends to be switched, the left-hand input of amplifier 19 is reduced to cause rapid switching of device 27 whose other output operates its associated indicator 16, 17, or 18.
