Title: Improvements in or relating to fluid pressure control systems
Inventor: BRISTOW HUBERT RONALD
IPC: G05D16/20
Filed: 1963-05-13
Abstract: 1,090,021. Automatic pressure control. ELLIOTT BROS. (LONDON) Ltd. May 8, 1964 [May 13, 1963], No. 18938/63. Heading G3R. In a system for controlling fluid-pressure, a signal dependent on the pressure is compared with a desired value signal which is selected by a velodyne follow-up servo, any difference serving to correct the pressure automatically. A desired fluid-pressure in a conduit 4 is selected by a unit 13 controlling a velodyne follow-up servomotor 12 adjusting one input of a differential unit 10, the other input of which is adjusted by a capsule 9 in dependence on actual pressure. Any difference between the two inputs, representing a pressure error, produces an electrical output which, after amplification at 7, controls an electric motor 5 to correct the fluid-pressure in conduit 4 by adjusting a valve 3 associated with high and lowpressure sources 40, 41. The selected pressure is indicated by a unit 15 coupled through a synchro link 14 with motor 12. A preset angular correction unit (not shown) associated with the output of motor 12 compensates for any non-linearity. Alternatively a number of selectable detector units, each covering a narrow range of pressures, may be employed. By changing over a switch 18, rendering amplifier 7 inoperative, and closing the output of valve 3, motor 12 reduces the output of the differential unit 10 to zero so that unit 15 indicates the actual pressure in conduit 4 and any subsequent variation due to leakage. Periodic variation of pressure may be produced by applying a signal of appropriate waveform at 17. Motor 12 may be operated continuously to vary the pressure according to a predetermined law. A system having similar features and involving a control unit 33, a followup servomotor 32, a differential capsule 29, and a differential unit 30, controls a valve 23 to maintain a constant difference between the pressures in conduits 4 and 24.

Title: Method of and apparatus for treating liquids with gases or vapours
IPC: C11B3/14
Filed: 1951-08-16
Abstract: The liquid in a vessel or still, e.g. oils, waxes or resins to be deodorized, fatty acids, oils &c. to be distilled or paraffins to be oxidized with air, is continuously circulated by a plurality of gas or vapour uplift pipes or other conduits which discharge liquid at different heights in the vapour space of the still. This destroys the foam and prevents carry-over of liquid with the vapours.  The still of Fig. 1 is provided with two concentric uplift pipes 2, 3, the outer terminating <PICT:0707468/III/1> <PICT:0707468/III/2> short of the inner at each end and both extending above the liquid level at their upper ends and below the liquid level at their lower ends. Pipes 5, 6 for introducing gas or vapour, e.g. steam, into the uplift pipes are provided and baffles 7, 8 for deflecting the discharged liquid into the form of a curtain falling back to the bulk of the liquid.  The pipe 3 may be divided longitudinally or a plurality of pipes used.  A heating coil 12, which may also be used for cooling, and a steam or air distributer 13 are also provided.  In the vapour space is a liquid-vapour separator 9, 10, trapped liquid draining to a gutter 11.  The apparatus of Fig. 2 (not shown) is similar to that of Fig. 1, but a mechanical stirrer is provided, the baffles are differently arranged and the liquid-vapour separator is as shown in Fig. 3.  The stirrer may also rotate the uplift pipes or baffles, imparting a rotation to the liquid.  In Fig. 3, in addition to the central uplift pipes 40, 45, an annular uplift passage 52 is provided to which steam is supplied by pipe 48. Heating (or cooling) coils 49, 50 are provided and a steam distributer 51.  The central uplift uplift pipe 40 depends into a well 41.  The discharge from pipes 40, 45 is deflected by baffles 43, 47 and falls on to the liquid rising out of the passage 52 or on to an annular guide surface 53 from which it is returned to the main body of liquid.  The outlets from the steam distributer 51 may be arranged to give a rotary motion to the liquid in the still.  The vapour off-take 54 and cover 55 of the still may be jacketed, the jacket being evacuated for insulation or a cooling agent circulated therein.  The part 56 of the vapour separator 56, 58 may be similarly jacketed to insulate the spaces above and below the part 56.  In examples: (1) ground-nut oil is deodorized in the apparatus of Fig. 1 by vacuum steam distillation of the undesired constituents, circulation being effected also by steam. The oil is then cooled to 50-80 DEG C. by coil 12.  (2) Partially purified ground-nut oil is deodorized in the apparatus of Fig. 3 by steam distillation at 150 DEG C. and 5 mm. pressure for 2 hours. The oil is cooled to 110 DEG C. and run off to a second vessel where it is further cooled under vacuum.

Abstract: 1381960 Storage CONSTRUCTIONS MILLS K 26 April 1972 [12 May 1971] 19438/72 Heading A4T A carrier 1 runs in a corridor on storage rails 2, 3 and has a raisable surface 5 so that articles can be raised or lowered from a storage position. The carrier is automatically controlled from a remote position and its power supply and the control signals for its automatic selector are transmitted through a cable 7 from a fixed outlet 8 to a slip ring device 11 for the carrier circuits 12. The cable 7 passes through a guide 9 to a winch 10 which takes in or pays out the cable. The winch drum 10 on a shaft 14, Fig.2 is driven through a coupling 17 from a shaft 15 in turn driven from a shaft 18 through either a one way drive 21-24 or 25, 26. The shaft 18 has a pulley 19 driven by a chain 20 from the carrier wheels and the coupling 17 is of the electromagnetic powder type so that when the cable is being pulled off the winch it can only turn in direction F3 opposite to the turning caused by the chain 20 through drive 25, 26 in direction F1 by overcoming the friction of the coupling 17 so that the cable always remains taut. A transfer device 100, Fig.6 to take the carrier 1 to another corridor or the entrance and exit points has a cable 107 from an external point connected through a second winch 110 to a connector 108 to which the cable 7 is connected. The transfer device may include an elevator to raise the carrier 1 to other storage levels or may be able to move into a lift. In all examples direct cable connections are made to the cable 7 to ensure continuity although the cable 7 may be disconnectable to allow the carrier to be left in a storage corridor while other movements are made.
