Patent GB-2028943-A (GB)
Title: Anti-skid Regulating Systems for Vehicle Braking Systems
IPC: B60T8/1761
Filed: 1979-08-22
Abstract: Anti-skid regulating system for a vehicle braking systems has an evaluation circuit which derives from a wheel speed signal VR a reference signal VB approximating to the vehicle speed VF, and compares the wheel speed signal with this reference signal to provide brake pressure control signals. The reference signal varies with time initially at a fixed rate, e.g. corresponding to 0.7 g but at the end of the first cycle of operation (time t2 in Fig. 3) the slope is increased in dependence on the difference  DELTA V between the wheel and reference speeds. Alternatively, if the wheel speed exceeds the reference speed before the end of the first cycle (Fig. 3), the slope is reduced. The first cycle terminates when wheel acceleration reaches a predetermined value. <IMAGE>

Patent GB-2059205-A (GB)
Title: Apparatus for supplying a series of electrical pulses
IPC: H03K3/55
Filed: 1979-09-07
Abstract: A series of high energy, high frequency pulses are supplied to an inductive load 4 by successively discharging a series of capacitors 1, 1', 1'' etc through respective switching circuits A, only one of which is shown in detail. Each pulse is initiated by a trigger impulse on line 15, 15A etc. This fires thyratrons 12 and 13 to discharge capacitor 1 thus forming the first part of a pulse during which current flows in a forward direction through the load 4 until the capacitor has a reverse charge. The forward current is detected by transformer 19 which fires thyratron 14 allowing the capacitor, which now has a reverse charge, to discharge through the load to form a second part of the pulse during which current flows in a reverse direction. A further transformer 18 ensures that, when one thyratron 12 or 13 has fired the other thyratron 13 fires soon thereafter. <IMAGE>
