Title: Traffic actuated control system
IPC: G08G1/08
Filed: 1958-11-18
Abstract: 909,938. Road signals for controlling traffic. LABORATORY FOR ELECTRONICS Inc. Nov. 18, 1958 [Nov. 18, 1957], No. 37145/58. Class 118. A traffic control system controlling an intersection having a plurality of interfering traffic lanes comprises a parent controller for according right-of-way cyclically to each of the lanes except two, which interfere with certain other lanes but not with each other, and two minor movement controllers each associated with one of the two lanes and actuated by traffic in the associated lane to remove control of the signal lights from the parent controller whilst rightof-way is accorded to its associated lane by each minor movement controller. As described, the system is applied to cross-roads (Fig. 1) having straight-through traffic on roads A and B and left-turn (interfering) traffic on road A operating separate road pads 101 and 101<SP>1</SP>. The main traffic of phase A and phase B is controlled by traffic signals operated by a parent controller of the type described in Specification 909,937, and the two streams of turning traffic, phase A minor south and phase A minor north, are each separately controlled by signal lights operated by a minor movement controller of the kind described in the same Specification. Actuation of either or both of detectors 101 and 101<SP>1</SP> inserts the associated minor phase after the next phase B period and prevents further operation of the parent controller. The interconnection of the parent controller and the two minor movement controllers is so arranged that when both minor phases are required they commence simultaneously and control of the signal lights is not returned to the parent controller until both minor movement controllers have finished their signal cycle. If, say, the A minor south cycle has finished but, owing to repeated actuation of the detector 101<SP>1</SP>, the phase A minor north period has been extended, the A minor south traffic will be stopped and the opposing A major north traffic allowed to proceed, the A major south traffic being still held up whilst the A minor north traffic proceeds. If the parent controller is of the type in which actuation of a phase A major detector during a phase A minor period would operate to prolong the duration of the next phase A major green period, the circuit arrangement of Fig. 8 (not shown) is employed in order that when only one minor phase is in operation the operation of either phase A major detector is nullified. This provides that there is no extension of the next phase A major green period due to waiting traffic, since phase A major traffic is already flowing in one direction.

Abstract: 925,826. Automatic signalling passage of vehicles. GENERAL RAILWAY SIGNAL CO. Oct. 20, 1961, No. 37688/61. Class 118. [Also in Groups XIX and XL (c)] A system for detecting objects moving along a predetermined path comprises transmitting means positioned and directed to transmit repetitive energy pulses on alternately different carrier frequencies F 1 , F 2  across the path, receiving means positioned and directed to receive reflections of the transmitted pulses by an object moving along the path and gated frequency-discriminating means permitting the receiving means to provide an output signal in response to a reflection signal on a particular one of frequencies F 1 , F 2  only in a predetermined interval beginning after the transmission of the pulse on the particular frequency and prior to the transmission of the next pulse on the other of the two frequencies and such that reflections of each transmitted pulse having a total propagation time longer than the period between successive pulses and shorter than twice this period cannot produce an output signal from the receiving means. The invention is described as applied to detecting vehicles in road traffic lanes L, R, Fig. 1B, utilizing sound wave pulses on alternate frequencies 20 kc./s., 25 kc./s., and ensures that pulses reflected from vehicles in lane L do not affect the lane R receiver output, and vice versa. The apparatus 9 comprises a multivibrator 20 providing outputs, Fig. 4a, d, pulsed oscillators 22, 32 to afford outputs, Fig. 4g, from transmitting transducer 11, gates 29, 39 opened by outputs, Fig. 4a, d respectively, a limiter 40 to reject echoes from distant reflectors, and a gate 47 to reject transmitted pulses, Figs. 4m, n, p, q (none shown). As vehicle 16 passes through the beam of transducer 11 of unit 9 the series of pulses appearing at the output of amplifier 48 cut off a relay control valve 50 which causes relay DR to be de-energized. The relay is utilized to operate a counter 51 or traffic control signal 52. It is stated that there is no interference from animals or human beings, the fur or feathers of the former and the clothing of the latter tending to absorb, rather than reflect, the ultrasonic waves.

Abstract: 899,864. Railway track ballast cleaning apparatus. PLASSER, F., and THEURER, J. Nov. 16, 1959 [Nov. 18, 1958], No. 38802/59. Class 104 (2). In a railway track ballast cleaning apparatus a cleaning means guided in the region of the ballast bed and moved along below the track in the longitudinal direction of the track subjects the ballast to a cleaning process within the cross-sectional contour of the bed. In the arrangement shown in Fig. 1 three conveying worms 2a, 2b, 2c mounted on a support frame 1 are rotated by motors 4 through drives 3. The apparatus is located beneath the sleepers 13 and is pulled through the ballast 14 by winches 6, driven by the motors 2 acting on ropes 7 secured at one end to the rail 12 or a rail fastening. The conveying worms 2a, 2b, 2c are of different diameters, the smallest diameter worm 2a of which is arranged in the front of the apparatus. The foremost worm 2a is provided with teeth or transverse hoops to facilitate taking up the ballast 14. Some of the conveying worms, preferably the worm 2a, are given a shaking as well as a rotary movement. The pitch of the single or multiple thread worms is such that only material of a small grain size is removed from the ballast while material of a large grain size, e.g. above 30 m/m., is left beneath the sleepers 13. Pivotal or slidable guide members 5, provided on each side of the apparatus, have guide rollers at their ends to engage the web of the rail 12 when in the operative position. The apparatus is also guided by slide-bars or skids which engage the underside or ends of the sleepers 13. Shaped clearing-plates 8a, 8b on each side of the apparatus return ballast to a position within the contour of the ballast bed. Guide-plates 10 push the rejected material to the side of the apparatus. The conveying worms may be arranged obliquely to the track or, alternatively, the apparatus may be wedge-shaped in plan view. The conveying worms may be replaced by a scraper chain, the conveying elements of which are so spaced that only small grain size material is removed. One or more screens, such as a screening cylinder which carries. out a vibratory as well as a rotary movement, may replace the conveying worms and in this case the rejected material is removed by compressed air.
