IPC: G08G1/081
Filed: 1970-02-10
Abstract: 1,259,435. Road traffic signals. OMRON TATEISI ELECTRONICS CO. 10 Feb., 1970 [21 Feb., 1969; 8 March, 1969], No. 6365/70. Heading G4Q. A system for controlling traffic over a wide area divided into a number of subareas comprises a master controller controlling a plurality of submaster controllers, each submaster controller controlling a plurality of local controllers related to a particular subarea and each local controller controlling a number of traffic signals. As shown in Fig. 1 there are two subareas controlled, respectively, by submaster controller 2, 3. Submaster controller 2 controls local controllers 4, 5 and submaster controller 3 controls local controllers 6, 7, 8. The traffic in the two subareas is sensed by detectors 9, 10, respectively, and this information is supplied to the master controller 1. On the basis of this information the master controller determines the traffic signal cycle for all the traffic signals in the wide area. This cycle is the same for all the signals and hence the master controller 1 transmits the same "cycle pulses" to the submaster controllers 2, 3. In addition, the master controller transmits the same "synchronizing pulses" to the submaster controllers, these pulses being in synchronism with the signal cycle. However, the master controller 1 generates different "offset signals" corresponding to the different information received from the detectors 9, 10. Thus, the offset signal derived from the detector 9 is supplied from the master controller to the submaster controller 2 and the offset signal derived from the detector 10 is supplied from the master controller to the submaster controller 3. Submaster controller 2 generates synchronizing pulses which correspond to the synchronizing pulses received from the master controller but are displaced in time by the related offset signal, the synchronizing pulses generated by the submaster controller being supplied to the local controllers 4, 5. Similarly, submaster controller 3 generates synchronizing pulses which are displaced in time by a different offset signal and supplies these pulses to the local controllers 6, 7, 8. Two embodiments of the submaster controllers are described with reference to Figs. 2-4 (not shown), these embodiments utilizing digital counting and gating circuits.

Abstract: 1,266,156. Regulating I.C. engines. A. J. LAKE. July 4, 1969 [July 8, 1968], No.32396/68. Heading F1B. A device for controlling the position of a throttle mechanism of a motor vehicle engine during vehicle cruising and for allowing automatic cancellation of the control e.g. during braking or further power conditions, comprises a base-plate 21 securable to the vehicle and pivotally and slidably supporting a setting member 11 having a stop 14 for an arm 16 pivotally attached to the engine throttle mechanism 18. The stop 14 is adjusted by hand lever 27 to the required cruising speed position between low-speed stop 24 and high-speed stop 26 on base-plate 21. During overtaking and climbing, when additional power is required, the arm 16 moves away from stop 14 towards stop 26. During braking, depression of brake pedal 39 (or equivalent member) causes the setting member 11 to pivot about pin 12 and move the stop 14 out of the path of arm 16 thereby permitting the arm to move towards stop 24. On subsequent acceleration, the arm slides up incline 46 back to the position shown. Bowden cables 29, 41 may be replaced by push rods or hydraulic or electrical mechanisms.

Abstract: 1297678 Stratified fuel charges; recyling exhaust P S MYERS 9 Feb 1970 [20 June 1969 2 Feb 1970] 6011/70 Heading F1B In an I.C. engine having intake and exhaust ports a method of providing a stratified charge comprises providing a quantity of fuel/air mixture in the combustion chamber in proportion to the engine load and providing a quantity of exhaust gas formed form the burning of the previous fuel/ air mixture in inverse proportion to the engine load to complement the quantity of fuel/ air mixture, the bulk gas and quench gas portions of the fuel/ air constituent of the stratified charge being respectively exhausted into first and second gas chambers, the portions being selectively returned to form the exhaust gas constituent for a subsequent stratified charge. The method improves fuel utilization and reduces objectionable exhaust emissions at partial engine loads. A carburetter 26, Fig.1 forms a mixture which produces  desired reduced nitrous oxide emissions after ("min NO F/A mixture") which is admitted to the combustion chamber through an auxiliary inlet valve 29 and a main inlet valve 28. The exhaust ports are controlled by main exhaust valves 36, 37 and auxiliary exhaust valves 38, 39 which control the flow of exhaust gases to and from exhaust chambers 40, 41. The flow of gas through Venturis 42 induces an air-flow through a conduit 43 having a check-valve 44, a valve 45 which is fully opened by a bi-metallic element 47 when the engine is cold and a valve 46 controlled by accelerator position to be fully open when the engine is running at minimum load at which a maximum amount of exhaust gas/ air mixture ("EG/A mixture") is required. The air may be introduced by an air pump instead of a Venturi. Chambers 40, 41 may be common to several cylinders. The timing of the respective auxiliary and main valves is varied to provide the desired quantities of min NO F/A mixture and EG/A mixture. The invention may be applied to sparkignition and Diesel engines or to rotary piston engines. In the latter the products of combustion formed by the burning of the min. NO F/A mixture are exhausted at the first end of the piston and a portion thereof is redrawn at the opposite end of the piston with admixed air.

Abstract: 1320986 Frequency monitoring N J FROMENT & CO 8 April 1971 9124/71 Heading G1U In order to detect deviations of the frequency of a supply LN from the natural frequency of a multi-vibrator Tr1, Tr2, pulses derived from the supply, via a circuit comprising a resistor R13, a capacitor C1 and a Zener diode D11, are fed into the multi-vibrator, via a Zener diode D10 and a resistor R9, in such a way that providing the supply frequency lies within a small frequency range centered around the natural frequency of the multi-vibrator (e.g. 50+2c/s) the multi-vibrator is locked to the supply slightly out of phase with it, and if this small phase difference exists then a phase sensitive circuit, comprising transistors Tr3 and Tr4 energized by the multi-vibrator and diodes D3 and D4 energized by the supply, maintains an SCR, and hence a lamp L, on, whereas if the supply frequency lies outside the small range referred to above the multi-vibrator is not locked to the supply and the lamp is flashed at the difference frequency. When the multi-vibrator is locked to the supply frequency, the phase relationship is such that transistor Tr1 is on during the positive-going zero crossover of the supply applied to diode D4 and therefor transistor Tr3 is non-conductive so that, as a result, a positive signal is applied to the gate of the SCR which therefore conducts. Soon after the positivegoing zero crossover of the supply, transistor Tr1 goes off and transistor Tr3 conducts thereby earthing the gate of the SCR, but this is ineffective since the SCR is, by now, conducting. At the end of this half-cycle of the supply, the SCR would normally become non-conducting but for the fact that a similar situation now obtains with respect to transistors Tr2, Tr4 and diode D3, and the result is that the SCR is conductive continuously. Once the multi-vibrator is no longer locked to the supply frequency, the supply and the multi-vibrator will come into the above phase relationship cyclically, at the difference frequency, and it can then be seen that the SCR will be energized at the difference frequency. A thermistor R16 is included in the multi-vibrator circuit to compensate for temperature variations.
