Title: Measurement of fluid flow
Inventor: BECKINGHAM WILLIAM SIDNEY
IPC: G01F1/684
Filed: 1965-10-27
Abstract: 1,084,653. Measuring rate of fluid flow electrically. CONTACTROL Ltd. Sept. 28, 1966 [Oct. 27, 1965], No. 45565/65. Heading G1N. [Also in Division G4] The rate of flow of a liquid is measured by applying a pulse of electrical energy to a heater immersed in the liquid, and measuring electrically the time required for the heated liquid to travel a predetermined distance. In one embodiment, Fig. 1, a pulse generator 8 is controlled by motordriven cam contacts 6 to apply a regular train of pulses to a heater 5 immersed in the flowing liquid. These pulses are detected by temperature sensitive semi-conductor rectifiers 9 which control a second pulse generator 12. The phase difference between the input and output pulse trains, i.e. the time of travel of the heated liquid, is measured by generating a saw-tooth pulse by means of a motor-driven potentiometer 2 (driven in synchronism with the contacts 6) and sampling by relay 13 the voltage level at the instant that the output pulse occurs. This voltage is stored on capacitor 14 and measured by amplifier 15 and meter 16. In an alternative embodiment, Fig. 2 (not shown), a pulse is applied to the heater only when a preceding pulse is detected by the temperature-sensitive device. The arrangement thus operates as an oscillator, the frequency of which depends upon the time difference between the input and output signals. The number of output signals may be counted to indicate volumetric flow, and the rate of flow indicated by integrating the output signals. The details of the mounting for the heater and temperature sensitive device are also disclosed, Figs. 3 to 5 (not shown).

Abstract: 1,193,546. Cathode-ray tube displays. INTERNATIONAL BUSINESS MACHINES CORP. 27 Sept., 1968 [4 Oct., 1967], No. 45905/68. Heading H4T. In a display system comprising a plurality of display devices, specifically cathode-ray tubes, each of which displays information from different respective data trains on a television type line raster, the fly-back of the (horizontal) line scan is controlled by a source of pulses common to all the display devices whilst the (vertical) frame fly-back of individual display devices is controlled by the coincidence of a line fly-back pulse and a frame fly-back control signal included in the data train appropriate to the particular display device. Fig. 1, shows an embodiment in which the pulses controlling the line fly-back are recorded on a common track 5 on a recording member 3 whilst the data to be displayed together with frame fly-back control pulses are recorded on respective tracks 7, 9 ... n appertaining to the different display units NO1, 2 . . . N, the recordings being effected over line 17 via read-write heads 11, 13, 15 . . . n<SP>1</SP>. During play-back, the line fly-back control pulses are fed via amplifier 21 to a clock logic circuit 23 which, in addition to producing pulses on line 25 to control the recording over line 17, supplies fly-back control pulses via a driver amplifier 29 to a line 31 which.feeds the control pulses to a receiver in each of the display units such as the receiver 47 in Display Unit No. 2. The latter includes a further receiver 49 to which the data on the track appertaining to this display unit is fed via driver amplifier 37, amplifier 35 and read-write lead 15 associated with such trace, i.e. track 9. The outputs of the receivers are fed to a digital control logic circuit 45 (Fig. 2, not shown) which operates to supply line fly-back pulses to the horizontal ramp generator 63 and to supply the data to be displayed to the intensity control electrode or the display tube over line 51 and the frame fly-back control pulses to the vertical ramp generator 57 over line 55 via respective gate circuits. These gates circuits are controlled by a latch circuit such that when a line fly-back control pulse received by receiver 47 concides with the reception by receiver 49 of the frame fly-back control pulses (which are interposed with the data to be displayed) the gate supplying the display data to the tube is blocked and the gate supplying the frame fly-back control pulses to the vertical ramp generator 57 is opened so that fly-back of this generator is produced.
