Filed: 1974-09-26
Abstract: 1436933 Phase comparators MULLARD Ltd 26 Sept 1974 41904/74 Heading H3A A circuit for comparing the phases of two signals over a phase difference range of 360n degrees comprises n phase comparators each responsive to a respective one of n consecutive waveforms of each of the two signals and means for combining the n comparator outputs to give a signal whose magnitude is dependent on the phase difference. In one embodiment, Fig. 1, the two input signals A, B are applied to divideby-two stages 4, 5 whose outputs are fed to bistables 6, 7 which produce pulses whose width depends on the phase difference. The outputs of the bi-stables are then fed to a summing integrator 8, 9, 10 to provide an output at 3 proportional to the phase difference over a range of 720 degrees (n = 2). In a second embodiment, Fig. 4, where n = each signal is fed to a respective 2-stage shift register 31, 33; 32, 34, the direct and inverse outputs of each stage being fed to EXCLUSIVE-OR gates 35, 36 which feed the variable width pulses to the combining integrator 8, 9, 10. In an n-stage version of this latter embodiment, Fig. 7 (not shown), correct starting states of the bi-stable stages of the shift registers are ensured by feeding the outputs of the last two stages to NOR gates (N1, N2) whose outputs are fed to reset inputs of the other stages. With the embodiment of Fig. 4 an indication of frequency difference is given Fig. 8 (not shown) by feeding the outputs of the two EXCLUSIVE-OR gates to a NAND (41) gate whose output is fed via second NAND gate (42) to the clock input of bi-stable 31. The inverted EXCLUSIVE-OR outputs are fed via similar gates (34, 44) to the clock input of bi-stable 32. With this arrangement, a high or low level output is produced depending on which of the two input signals has the higher frequency.

Title: Engine control system for vehicles
IPC: F02N11/08
Filed: 1974-09-30
Abstract: 1477022 Starting prime movers NIPPONDENSO CO Ltd TOYOTA JIDOSHA HANBAI KK and TOKAI RIKA DENKI SEISAKUSHO KK 30 Sept 1974 [8 Oct 1973] 42404/74 Heading H2H A control system for a vehicle having an internal combustion engine comprises means for sensing depression of the clutch pedal and means for sensing rotation of the engine and further means for sensing movement of the vehicle, the arrangement being such that when the vehicle is brought to rest, the engine of the vehicle stops and is restarted by operation of the clutch pedal, the system being disabled when the driver leaves the vehicle. With the vehicle at rest and the engine stopped, operation of the ignition switch and a further manually operable switch causes the control system to be supplied from the vehicle battery by means of a transistor and a self-holding relay. Partial depression of the clutch pedal closes a switch whereby a relay is energized to connect the ignition system to the vehicle battery. Further depression of the clutch pedal closes a second switch which causes the starter motor to be energized so as to start the engine. When the engine is rotating the output from the vehicle generator causes de-energization of the starter motor. The vehicle is then driven in the normal manner by depressing the accelerator pedal and releasing the clutch pedal, the ignition circuit being maintained energized by means of a circuit responsive to a device sensing movement of the vehicle. When the vehicle is brought to rest by depression of the clutch pedal and release of the accelerator pedal, the starter motor circuit is disabled by the generator output and the ignition circuit maintained energized. Should, however, the clutch pedal be depressed when the vehicle is stationary the ignition circuit will be de-energized. Further, should the driver leave the vehicle whilst this is stationary the engine automatically stops. Means are provided to maintain the ignition circuit energized and the engine running should the vehicle be stopped on a hill and should any of the vehicle services be in use, such as headlights, demister, air conditioning, and turn indicators.

Title: Improvements in or relating to Electrical Static Inverters.
Inventor: CROUCHMAN ERNEST LESLIE
IPC: H02M7/5381
Filed: 1965-10-08
Abstract: 1,177,642. Converting. SMITHS INDUSTRIES Ltd. 9 Jan., 1967 [8 Oct., 1965], No. 42714/65. Heading H2F. An inverter of the type in which a transformer is energized through alternately conductive semi-conductor devices has means responsive to the output to delay the switching on of each device until the switching off of the other has caused the output to reverse. Overlap in conduction due to charge storage may thus be avoided. The inverter output stage 6 is controlled by a driver stage 5 from a bi-stable circuit 4 triggered by a pulse generator 16. When the bi-stable circuit changes over in one sense one diode 32 conducts and cuts off transistor 31. This applies a blocking bias to transistor 11 which cuts off when the charge carriers are dissipated and the resulting reversal of the voltage across a secondary winding 42 cuts off a diode 44. The reversal of the bi-stable circuit had cut off the associated upper diode 32 so that transistor 10 now conducts. A steady bias is provided by a circuit 45, 46 and the dotted diode circuit may provide an additional switching control dependent upon the rate of change of output voltage.
