Patent GB-1086187-A (GB)
Title: Improvements in electronic automatic control systems
IPC: H03K5/01
Filed: 1965-03-25
Abstract: 1,086,187. Automatic frequency control; staircase generating circuits. COMPAGNIE FRANCAISE THOMSON - HOUSTON - HOTCHKISS BRANDT. March 25, 1965 [March 27, 1964], No. 12784/65. Headings H3A and H3P. In a retro-active control system, e.g. an automatic frequency control system, having a search circuit for facilitating initial locking in, the control signal from the search circuit is maintained after locking in to enable a low level of the retro-active control signal to be employed. As described the output from an oscillator 1, Fig. 4, is fed, together with that from a reference oscillator 3, to a frequency comparator 2, the resulting error signal output being fed to control a reactance element 4, e.g. a diode, a valve or a transistor, in the resonant circuit of the oscillator 1. If the frequency of the oscillator 1 lies outside the range of the comparator 2, a staircase generator 6 is switched on to provide a sweep voltage for the reactance 4. When the oscillator 1 comes within the control range, the output from comparator 2 stops the staircase generator, to provide a constant voltage which is then added to that from comparator 2 to control element 4. The staircase generator, Fig. 1 (not shown) comprises a pulse generator 1 feeding a binary divider chain (21, 22 . . . 2n), the output from each stage being half the frequency and twice the amplitude of that from the previous stage. These outputs are then summed in an adding circuit (40), e.g. a resistive network, Fig. 3 (not shown).

Patent GB-882611-A (GB)
Title: Improvements in sea water distillation method and apparatus to provide a superpure distillate
IPC: B01D1/28
Filed: 1959-04-16
Abstract: <PICT:0882611/III/1> In a distillation plant for the production of both potable and superpure water from sea water, an evaporator 10 is employed in which steam vapourizes sea water by out of contact heat transfer and the vapour, after being freed from entrained salt-carrying water in chambers 22 and 24, is discharged by conduit 50 into a condenser 12 where part of the vapour is condensed to potable water, the remainder passing by conduit 62 into a demister 64 where a filter 70 removes moisture.  The vapour thus dried is sucked into a conduit 66 by a steam jet pump 68 which also introduces steam into the system, so that a mixture of steam from the pump 68 and vapour from demister 64 is passed by conduit 28 into the evaporator heat exchanger 26 to heat the water.  The steam then condenses to superpure water, which is collected in steam chest 34.  The condenser 12 is cooled by a conduit 52 carrying sea water which is subsequently passed by conduit 30 to feed the boiler chamber 20 of the evaporator. Preferably the jet pump 68 has a variable nozzle to control the amount of vapour circulating from the condenser 12 to the evaporator 10, the nozzle being operated by a control unit 76 in response to a pressure-sensitive element 78 in the steam chest 34.  The amount and rate of potable water production is then regulated by opening or closing a low pressure steam inlet 86 to adjust the pressure in the steam chest 34.  Further control is facilitated by a sea water control valve 56 which is operated automatically by a control unit 58 responsive to temperature and/or pressure changes sensed by an element 90.  The plant is said to be most efficient when the greatest quantity of superpure water is produced.
