Abstract: The apparatus according to the invention relates to a guided vehicle control process and apparatus which comprises passive beacons, as well as radars permitting the detection thereof. The presence or absence of a beacon permits the automatic control of a train, e.g. with a view to automating the driving thereof. The apparatus according to the invention uses retrodirectional beacons and/or beacons inducing a polarization rotation of the radiation received. The use of retrodirectional beacons induces a change of frequency by Doppler effect of the reflected radiation. The change of the Doppler frequency and/or the polarization rotation of the radiation improves the signal-clutter ratio and/or the separation of the transmission and reception channels.

Abstract: The valving element, according to the first embodiment depicted, comprises a plate-type element having an undulated or scalloped edge or periphery. The plate-type element has a plurality of flow ports formed therein each of which subtends an arc drawn from the radial centre of the element. The ends of the ports, which other wise would be subject to fatigue, failure and fracture, are spaced further from the edge than in prior art practice. Accordingly, the shock of impact of the plate-type element on opening or closing is less likely to precipitate fatigue and failure of the port ends. Additionally, at a plurality of locations about the periphery, the plate-type element has linear portions upon the plate-type element impacting on any of these linear portions, it will make a line contact which more readily disperses the impact shock.
