161 CORRECTION FOR NON-LINEARITY IN BRAKING GB8518487 1985-07-22 GB2162970A 1986-02-12 WICKHAM DAVID JOHN; POOLE JOHN DAVID
A railway vehicle brake actuator employs an electric motor driving through a step-down gearbox to mechanically move the brake blocks. After the initial rubbing contact point the response of the system is non-linear and the motor feedback control involves compensation for said non-linearity. The motor output shaft is connected to a rotary shaft encoder so that the position of the actuator output member, and thus also the brake force applied, can be determined by pulse counting. The ideal relationship between a brake demand signal and brake force is linear. The actual relationship between actuator position and brake force is non-linear. Correction factors covering the whole operating range are stored in a memory against pulse count numbers and used as a look-up table in the feedback circuit to compensate either the feedback signal or the demand signal for the non-linearity of the response.

1506750 Optical generator with feedback THOMSON-CSF 4 July 1975 [5 July 1974] 28376/75 Heading G1A Such a generator controlled by a current has two terminals 3, 10 for this current connected to current amplifier A, with its output connected to L.E.D. L with a radiating surface close to and optically coupled by a transparent medium M to an end of an optical fibre F and to photodiode P connected to the input of amplifier A 2 , with its output connected to the input of A 1 . GaAs L.E.D. L and photodiode P which is a junction on a silicon substrate, are attached by electrically conductive weld layers to conducting substrate S. In the embodiment of Fig. 2 (not shown) the amplifiers are outside the substrate S. In that of Fig. 3 the amplifiers A 1 A 2 and photodiode P, are an integrated circuit on a silicon base. In the embodiment of Fig. 4 (not shown), the diode P and fibre F face opposite polished ends of laser diode (L 1 ).

169 Pneumatic PI relay with differential pressure amplifier - has two output signals varying in opposite directions DE1966901 1969-11-03 DE1966901A1 1975-05-07 BADER HORST DIPL-ING
The differential pressure amplifier has two output signals which vary in an opposite direction to one another. One of its input signals is tapped from a pressure divider which is loaded with the actual value and by the output signal varying in an opposite way. Its other input signal is formed by the same output pressure which is conveyed to the input by way of a timing element. When the actual value increases, the input pressure admitted via the pressure divider also increases and, with it, the other output signal in the same direction. The output signal varying in the opposite direction is linked to a resistance.
