Patent GB-2099146-A (GB)
Title: A phase difference flowmeter
IPC: G01F1/66
Filed: 1981-04-03
Abstract: In conventional phase difference flowmeters acoustic waves are transmitted in directions upstream and downstream of the flow and the phase difference on reception is measured. This phase difference can be used to calculate the flow rate. Improved accuracy of measurement is provided by converting (5, 5A) the two received signals into square wave form. These square wave signals are then processed at 6 and 6A so as to produce further square wave signals having the same relative phase as the outputs of 5 and 5A but reduced in frequency by a common fixed value. Since the frequency is now considerably reduced the phase difference can easily be measured and this is done by diffentiators 7, 7A, flip flops 8, 8A and an AND gate 9, the latter producing an output pulse whose duration is proportional to the phase difference. This duration is measured by using the output of the gate 9 to enable a counter 10 which is fed with clock signals from the circuit 2. The output of counter 10 is a measure of the phase angle and from this, circuits 11, 12, 13 and 14 calculate the flow rate which is displayed at 15 and used to perform a control function at 16 and 17. <IMAGE>

Patent GB-2099645-A (GB)
Title: Frequency synthesisers
IPC: H03L7/23
Filed: 1981-05-29
Abstract: A circuit arrangement for producing an output Fo is in the form of two phase-locked loops 5 and 6 fed with reference frequencies Fr and fr respectively, which differ by a small amount (e.g. they may be 10.1 and 10.0 KHz). This enables Fo to be adjusted in small steps each equal to the difference (Fr-fr), by adjusting the dividers 28 and 12 by unity in the same or in opposite directions. A signal derived from the first loop oscillator 22 is mixed in the second loop with a signal derived from the second loop oscillator 8 and the difference frequency selected by filter 11. The two reference frequencies Fr, fr may be derived from a common oscillator via variable dividers. Alternatively Fr may be derived from loop oscillator 22 via a fixed divider. <IMAGE>

Patent GB-2102499-A (GB)
Title: A device for stopping a fuel injection engine, especially a vehicle engine
Inventor: INDRA JAROMIR
IPC: F02M63/02
Filed: 1981-07-24
Abstract: The device comprises an injection pump 4 having an outlet coupled to return excess fuel to a fuel tank 1 by way of a pressure-reducing valve 6 and an electromagnetically-operated valve 81 which is biassed in the open position when the engine is running. When a switch 92 is turned "off" the valve 81 is closed whereby the excess fuel is directed through a pipe 55 to a hydraulic cylinder 5 and forces a hydraulic piston 51 to an extended position. This causes a control member 41 in the injection pump 4 to inhibit the supply of fuel to the engine to thereby stop the engine. The current is supplied to the valve 81 only for the short time needed to stop the engine. Thus the power required is significantly reduced. <IMAGE>
