Abstract
1,227,722. Selective signalling. A. PIERBURG AUTOUND LUFTFAHRT-GERATEBAU K.G. 13 Jan., 1969 [20 Jan., 1968], No. 1930/69. Heading G4H. [Also in Division G3] Apparatus for continuously evaluating deviations from the desired value of a quantity expressed in Aiken code comprises a register 12 holding the desired value and a counter 10 in which the complement of this value is set up. The measured value is then added at 14 to the counter as a sequence of pulses over a fixed time period t 1 . A control circuit then operates for a period t 2 to transfer the contents of the counter 10 to a register 16. According to whether the counter 10 has passed through zero or not, a descriminator 22 disables or enables a gate 21b whereby the value in 16 remains true or is inverted. The value in 16 is converted at 18 into a corrective analogue signal and switch 20 is psoitioned according to whether the deviation is positive or negative. At the end of time t 2 the counter 10 is again set up.
