Title: Improvements in Traffic Control Systems.
Inventor: THOMPSON GEORGE WILLIAM
IPC: G08G1/08
Filed: 1966-04-28
Abstract: 1,180,022. Traffic control systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. 24 July, 1967 [28 April, 1966], No. 18765/66. Heading G4Q. Traffic in a section of road used as a reservoir area for vehicles intending to use a particular channel subject to delay, e.g. through a toll booth or tunnel, is controlled by signals operated from a central control station whose input is from a detector just within the section on the entering side and from other similar detectors in adjacent sections of the road; the control station acts to prevent traffic from entering the section when it is approaching saturation, as indicated by vehicles coming to rest in the vicinity of the detector, so that a gap is left to permit movement of conflicting traffic, e.g. on cross-roads. Fig. 3 shows a plurality of such road sections I, II and III with intersections controlled by lights of which SR1, SR2 control traffic queuing for the tunnel while SN1, SN2 relate to parallel lanes for traffic not using the tunnel. There may be more than one tunnel lane (Fig. 2, not shown). At a central station are a data channeller D.C. and computer COM, while at each intersection are a master controller for the lights SN and a sub-controller ST for the lights SR and for signs permitting turning from the side roads into the queuing lane (Fig. 4, not shown). The central station also contains a mimic display with lamps indicating the state of the traffic signals and the data stored in the channeller D.C. Detector loops A2 and B2 signal the presence of vehicles, and a timer T is started when A2 is energized and stopped when B2 is energized. If this time is greater than a predetermined value, i.e. the average speed is below a critical value, queuing is indicated and signalled to the computer along line QS. The computer also receives information of vehicles entering the section at E2 and leaving it at passage detectors E3, and adjusts the predetermined time value accordingly. If appropriate, an inhibiting signal is sent along line IS to the sub-controller ST1 to prevent the lights SR1 from going green. It is permissible for the other lane light SN1 to be green when SR1 is red, but never vice versa. The inhibit signal should not shorten the green period of SR1 below a dangerous minimum but should then inhibit the next change to green. In the intervals of scanning the exit detector E3 and the lights SN2 and SR2 the computer performs other functions, viz: reading the queue detectors A2 and B2, calculating the inhibit time, transmitting the inhibit signals, updating the mimic display and printing out information, A practical intersection is described (Fig. 5, not shown) embodying the above principles. with a series of toll booths the exits from which are also monitored. Provision is made for pedestrian crossings at the entrance to the queuing area and for traffic turning out of the queuing lanes into side streets, which also may have queues for the same toll booths.

Filed: 1974-04-30
Abstract: 1467295 Liquid/liquid extraction EXXON RESEARCH & ENG CO 30 April 1974 [21 May 1973] 18817/74 Heading B1F Liquid-liquid extraction apparatus comprises a casing 11 containing a plurality of vertically spaced trays 12, 14, 16 defining spaces 20, 26, 32 wherein heavy phase from inlet 48 flows downwardly to outlet 52 and light phase from inlet 40 flows upwardly to outlet 54, the light phase flowing as a layer 86 in the upper part of each space adjacent the bottom of the upper tray and the heavy phase flowing as a countercurrent layer in the lower part of each space adjacent the surface of the lower tray. Downcomers 55, 57, 59 are provided for heavy phase whilst the risers for light phase comprise seal boxes, e.g. 82. Each seal box comprises a top wall 68, 88, an end wall (e.g. wall 11 of the casing) for laterally confining liquid under the top wall, a plurality of spacedapart underflow weirs 90-104 which extend downwardly distances which increase progressively in the direction of the end wall, and a plurality of apertures in that portion 88 of the top wall above the weirs. Suitably each seal box has its top wall at the level of the associated tray and further comprises (a) an inclined section 24 dividing the space above the tray into a mixing zone 28 and a settling zone 26; (b) a bottom plate 82 with an upwardly extending portion 84 to define the base of the seal box and the entrance thereto; (c) downcomer means 74 for entry of part of the heavy liquid arriving by downcomer 55 from the stage above for partial mixing of the two phases within the seal box and (d) an outlet orifice adjacent thereto for outlet of heavy phase and light phase that has past final weir 104. The downcomers 55, 57 are arranged to be above the seal boxes of the' next lower trays: A coalescer 44 comprising a vertical array of horizontally extending screens may be provided below the lowermost tray. In use, as the depth of light phase layer 86 increases it passes more weirs 90-104 and hence reaches more apertures 88. There is thus an automatic adjustment of effective apertured surface area upon variation of flow rate of light phase. The apparatus may be used for the extraction of aromatic or haphthenic constituents from hydrocarbon oil using phenol as solvent.
