Title: Improvements relating to apparatus for controlling or measuring fluid pressures
Inventor: PARKES JOHN FRANCIS ANTHONY
IPC: G05D16/20
Filed: 1963-05-13
Abstract: 1,086,932. Automatic pressure control. ELLIOTT BROS. (LONDON) Ltd. May 8, 1964 [May 13, 1963], No. 18937/63. Heading G3R. Fluid-pressure to be measured is applied to a liquid column and an element detecting the position of the end of the column controls a servosystem which maintains the element aligned with the end of the column and also operates a pressure indicator. As shown, the height of a mercury column 1 is dependent on the pressure of gas or vapour in a conduit 3 relative to a fixed pressure applied to a conduit 4. The pressure desired in conduit 3 is selected by operating a remote transmitter (not shown) connected to a synchronous receiver 22 the electrical output of which, after amplification at 20, controls a servomotor 17 to maintain, through gearing 19, receiver 22 in a null position and a carriage 6 in a vertical position corresponding to the desired pressure. Any difference between the height of the mercury and the position of carriage 6, representing pressure error, is detected by a transducer 5, a corresponding electrical signal from which is applied through an amplifier 15 to a servomotor 13 to correct the pressure in conduit 3 by adjusting a valve 10 associated with high and low pressure sources 11 and 12. The sensitivity of control may be made dependent on the magnitude of error. If gauged switches 8 are moved to their other positions and a valve 9 closed, the output of transducer 5 controls motor 17 so that carriage 6 is moved into coincidence with the mercury level so that a counter 25 indicates the pressure in conduit 3. The calibration may be checked by manual control of motor 17 to move carriage 6 to a position 26 at which the datum of a calibration error-correcting cam device 24 is adjusted until the reading of counter 25 is correct for that position.

Abstract: 1,165,443. Generating timing pulses. COMPAGNIE DES COMPTEURS. 25 April, 1967 [28 April, 1966], No. 19103/67. Heading G4C. In an arrangement for generating timing pulses from information in binary form presented in a series of pulses which normally include a sequence of pulses spaced apart by the bit cell period, the generation process continues even in the case where information data is lost. In the preferred embodiment (Fig. 1) binary information is recorded in a magnetic tape or drum by a NRZ method in which phase modulation is utilized. Signals from a reading head 1 are shaped by a peak detecting circuit 2 and passed to a monostable circuit 3, the output of which is utilized to trigger a further monostable circuit 13 generating timing pulses HD. The output HB of circuit 2 is also fed to a frequency servo circuit 5 producing an output voltage for controlling the frequency of a multivibrator 6, When the output pulses Hm of the multivibrator 6 are synchronized with the input pulses to circuit 5, a synchronization comparing circuit produces a signal A for opening AND gates 9 and 12 whereby triggering of the monostable 3 and the circuit 5 may continue even if information signals HB are lost, the multivibrator 6 then becoming free running.

Abstract: 1,224,464. Digital-to-analogue converters. ELLIOTT BROS. (LONDON) Ltd. 5 July 1968 [28 April, 1967], No. 19588/67. Heading G4H. In a digital-to-analogue converter system the digital signal is converted into a voltage of equivalent magnitude and the signal in a storage device is adjusted to the same value. A binarycoded input signal is applied on twleve leads 20-22 and entered into a register 26 by a pulse on lead 27. The stages of the register control switches 28 to which current from supply 30 passes to a resistor ladder 32. The analogue voltage output on lead 34 is applied to a comparator 36 which also receives the output from one of the storage devices 8-16. One of these is selected by signals on leads 38-40 which are recoded at 44 to mark one of leads 46A-46E. The marked lead closes switch 66 and enables a current source 54 and a current sink 56. One of these is made operative by the output of comparator on complementary leads 62, 64 so that capacitor 52 is either charged or discharged to cause the output of amplifier 50 to balance the signal on lead 34. At the beginning of an operation the rates of charge and discharge are fast, controlled by a signal on leads 60 from control logic 24. After a set period this signal ends and the charge and discharge are slow, the output of the amplifier, oscillating slightly about the correct analogue value.
