Abstract: 1506701 Measuring fluid-pressure electrically SCOTUS MARINE Ltd 5 March 1975 [6 Dec 1973(2)] 56694/73 and 56695/73 Heading G1N The fluid-pressure inside a pipe-line is sensed by two Piezo-electric transducers 12, Fig. 1, symmetrically mounted in each half 2, 3 of a ring 1 assembled round a pipe union P by bolts 6-9 whereby variations in fluid-pressure produce corresponding changes in the flexing of the two halfrings 2, 3 which are sensed by the transducers 12. The pressure e.g. in a cylinder of an IC engine is measured by Piezo-electric transducers 111, Fig. 8, located in recesses 112 in the side of a block 100 coupled by tube 103, Fig. 7, to the test pressure source. The pressure is fed to a chamber 102 in a central part 106 of the block 100 which has through passages 105 on either side of part 106, leaving a ring 107 surrounding the chamber 102. The transducers 111 are located symmetrically in the two halves of the ring 107 and sense the flexing of the half-rings with the pressure in chamber 102. Cooling air is passed through the passages 105. Circuitry is described for feeding the pipe-line pressure signals and the cylinder pressure signals to a dual trace CRO whereby the relationship between fuel supply and cylinder pressure for an IC engine can be exhibited. The cylinder pressure signals are also used to obtain an analogue RPM signal, and to provide a marker pulse representing top dead centre.

Abstract: 1384394 Blood pumps AVCO CORP 20 Dec 1971 [30 Dec 1970] 59201/71 Heading A5R A fluid-driven cyclically-operating blood pump has means 15 for sensing the pressure of the driving fluid, pressure-increasing means responsive to the sensing means during each quiescent period between pumping pulses to increase said pressure if it falls below a first level, and venting means 25 responsive to the pressure sensor in said quiescent periods to vent the pressure to ambient if it exceeds a second level higher than the first. An intraaortic balloon pump comprising a balloon 1, catheter 2 and a chamber 24 in an isolating chamber 4 is first charged with helium by means of a valve 21. Pump operation is synchronised with heart activity by circuits 10 and 11 which are responsive to an E.K.G. input to cycle a valve 12 between a pressure source 13 and a vacuum source 14 thereby causing an isolating membrane 3 to act on the helium driving fluid to inflate and deflate balloon 1. The circuit 10 also provides a signal to a multivibrator 18 causing gates 36 to 40 to open during said quiescent periods to pass the outputs of comparators 31 to 35 to further logic circuits, 40 to 51. If the sensed pressure during a quiescent period lies between +7 and -5 mm Hg, no action is taken. If the pressure exceeds +20 mm or is less than -20 mm a rapid-vent valve 25 opens and the pump drive 6 stops. If the pressure lies between +7 and +20 mm a slow-vent valve 26 opens until +7 mm is reached. If the pressure is between -5 and -20 mm and the time (T 1 ) since the quiescent pressure was greater than +5 mm exceeds 1 minute a refill valve 27 opens until +5 mm is reached, but if the time taken to reach +5 mm is greater than 10 seconds, indicating an excessive leak, valve 27 is shut, valve 25 opened and the drive 6 is stopped. If said time (T 1 ) exceeds 1 minute, valve 25 is opened and drive 6 stopped.

Abstract: 1305728 Gas turbine engine fuel systems MOTOREN-UND TURBINEN-UNION MœNCHEN GmbH 18 June 1970 [19 June 1969] 29725/70 Heading F1G A gas turbine engine comprises a torque pickup providing a pressure signal representative of the engine output torque, and a torque limiter which compares the magnitude of the pressure signal with a pre-set reference magnitude and causes the fuel control device to change the fuel supply rate according to a function of the deviation of the pressure signal magnitude from the reference magnitude, the torque limiter including two bellows arranged one within the other to form between them a closed chamber, which receives the pressure signal, the free end of the two bellows being arranged to open and close a spring- biased valve which controls the fuel control device. Helical gearing 43, 42 in the drive between gas turbine 3 and its load 5 produces an axial thrust on a layshaft 41 which is proportional to the transmitted torque. The axial thrust is exerted against the bellows 63 of a torque pick-up 6, in opposition to a fluid pressure supplied via a restrictor 62 to the interior of the bellows, so as to control the opening of a bleed valve 64, 65 and thereby provide a pressure in line 7 proportional to the torque. This pressure is applied to the annular bellows space 81 of a torque limiter unit 8 in opposition to the force of spring 82 so that bleed valve 83, 84 downstream of a restrictor 10 in a line 9 connects to the outlet of the compressor 1 is opened if the torque tends to exceed the maximum permitted value, the resultant reduction of pressure within a bellows 114 causing a fuel metering valve 113 to reduce the fuel supply. The torque limiter 8 may be put out of action by closing a valve 12.
