Abstract
1448719 Controlling vehicles on diverging track MESSERSCHMITT - BOLKOWBLOHM GmbH 30 Oct 1973 [9 Nov 1972 50440/73 Heading B7N In a vehicle control arrangement in which each vehicle carries a transmitter 11 which transmits to its rear via a signal attenuating line a signal having an amplitude inversely related to its speed and a receiver 12 having a sensitivity directly related to its speed which is coupled to the line to receive from a vehicle in advance and derive an output signal by which the vehicle spacing is controlled, two such lines 13, 14 are provided at each track divergent point, one on each side of the approach track 4, to one of which the vehicle transmitter and receiver is coupled by either coils 11<SP>1</SP> or 11<SP>11</SP> and 12<SP>1</SP> or 12<SP>11</SP> in dependence on the direction 5 or 6 to be taken at the point and the lines in the approach track 4 are cross connected. As shown vehicles 1 and 3 take the left fork hence have their transmitters 11 and receivers 12 coupled to the left line 13 by coils 11<SP>1</SP> and 12<SP>1</SP> and vehicle 2 taking the right fork has its transmitter and receiver coupled to line 14 by coils 11<SP>11</SP> and 12<SP>11</SP>. To prevent collision between vehicles 3 and 2 the lines 13 and 14 are cross connected either directly, Fig. 4 (not shown) or via amplifiers, Fig. 5 (not shown), so that until it leaves the junction vehicle 2 appears to vehicle 3 as if it is between it and vehicle 1. The attenuating line is described in Specification 1,406,674.
