Abstract: 1,250,089. Velocity determination. INSTITUTET FOR MIKROVAGSTEKNIK. 9 Dec., 1969 [10 Dec., 1968], No. 60140/69. Heading H4D. [Also in Division G1]. To determine the speed of an object relative to its environment e.g. that of a train relative to a rail 10, Fig. 1, a light source (not shown) illuminates the rail and the scattered light thereby produced produces noise type signals f(t) and f[t - (l/v)] in spaced detectors 11 and 12 respectively where l is the spacing of the detectors and v is the speed of the train. The output of detector 11 is fed to one input of a comparator 14 via a variable delay 15, the output of detector 12 being fed to the other input of the comparator. A servo-control to be described ensures that the delay 15 is adjusted so that its delay # is equal to l/v, i.e. that the inputs to the comparator, f(t - #) and f[t - (I/v)] are equal and in phase. The output Uc of the comparator is fed to a capacitor feedback type integrator circuit R5/F5/C5. The integrated output U 1  is representative of velocity v which can be displayed at 16. An analogue to frequency convertor A/F produces of signal of frequency fp proportional to the velocity. This is fed to a counter type " distance-gone " indicator and is fed as the servo-signal to control the variable delay 15. The above system is effective above a speed Vy, Fig. 3. Below this-speed however the short time constants of the comparator etc. and the fact that signals f(t) and f[t - (l/v)] will contain very low frequency components, render the value of U I  liable to large fluctuations corresponding to said components. Correction circuits are thus provided to make the value of U I  independent of the comparator output below velocity Vy. The average frequency of the signal f[t - (l/v)] is proportional to the velocity V for V < V y . The signal is thus low pass filtered Ch/Rh and detected h l  and smoothed R l /C l  to produce the D.C. value Uy, Fig. 3, proportional within the described limits, to V, the proportionality constant being less than that of signal U I . The fluctuating signal U I  and the steady signal Uy, are subtracted in circuit F 6  and when U I  falls below Uy, diode D 6  causes resistor R 6  to be added into the feedback circuit of amplifier F5. This raises U I  up to Uy 1 . Signal U I  is thus prevented from falling below Uy 1 . Circuit F 7 /D 7 /R 7 , Fig. 2 is used in the same manner to correct U I  such that it does not fluctuate above Uy 2 . A zener diode Z 1  breaks down at U z  so that U I  is allowed to go above Uy 2  for V>Vy. The compound variation of U I  with V thus becomes as shown in Fig. 3, solid line.

In use, a rolling movement of the vehicle causes precession of the rotor 10 about the trunnion axis. Once started, this precession is gravity aided, the gravity induced precession giving rise to a correcting torque on the vehicleto oppose the rolling movement. A damped pendulum (not shown) swinging in a plane transverse to the direction of vehicle travel, or an equivalent control gyro, causes actuation of the brake 13 on the side of the rotor 10 away from which the vehicle is rolling, so that the rotor planetates about the braked shaft 12, the resultant reaction forces acting to restore the vehicle. Overcorrection causes the other brake to be actuated, rapidly reducing the oscillations of the vehicle and stabilizer to zero. The rotor is driven by a highspeed D.C. motor 6, and a series wound starter motor 7 is provided, both being connected to the rotor shaft 8 by disengageable clutches 9. A ballast tank 16 filled with or emptied of fluid 17 in response to movement of the vehicle steering gear is used to adjust the instability of the gyro suspension for cornering. The brakes 13 are disc brakes grippable by hydraulically actuated calipers 14.
