| 730,589. Fluid-pressure servomotor-control systems; electrically-actuated valves. BAILEY METERS & CONTROLS, Ltd. June 23, 1952 [June 21, 1951], No. 15752/52. Class 135. [Also in Group XXXVII] A fluid-pressure relay comprises a first power means, e.g. diaphragm 19, responsive to an input fluid pressure and imposing a force on a force balance member 41 position ing a pilot valve 50 to establish an output pressure acting on a second power means 47 which imposes a balancing force on the member 41, and an outlet 21 leading the output pressure to a further presence sensitive device, either one of the power means being adapted to act on the member 41 through a cam 40 varying a spring 43 loading the member 41. Fig. 1 shows the relay applied to control the combustion of a forced draught furnace 1. The load on the furnace is measured by the pressure drop across an orifice in the fuel pipe 6 which, through a meter 7, positions the pilot valve 8, e.g. as disclosed in Specification 425,507, [Group XII], to establish a fluid pressure in the pipe 9 which, after passing a manual-automatic selector valve 14, splits into two branches 10 and 11. The pipe 10 passes through a relay 15, e.g. of the type described in Specification 461,389, and leads to the diaphragm 19 of a characterizing relay 12, while the pipe 11 leads to a diaphragm 20 of a characterizing relay 13. A device 16 on the relay 12 gives a loading air pressure through pipe 21 which acts through solenoid operated valves 24, 25, 26 and pipe 29 on a power device 5 actuating a damper 4 while devices 17, 18 on the relay 13 give loading pressures which act respectively in pipes 22, 23 which also act on the power device. A fan 3 in the furnace stack 2 has three speeds and at its low speed the fan electric motor control circuit energizes the solenoid valve 24 so that the pressure in pipe 21 acts to control the damper. At a certain load, the pressure to the power device 5 acts on a pressureoperated switch 30 to give the fan its intermediate speed and at the same time de-energizes solenoid valve 24 and energizes the valve 25, so that the pressure in pipe 22 controls the damper to give a continuous control of the draught at the intermediate fan speed. At a given load, the pressure in the power device operates the switch 30 again to put the fan into high speed, de-energizes valve 25 and energizes valve 26, so that the pressure in pipe 23 now operates the damper to give continuous draught control at the high speed. When the load at high speed decreases a given amount below the previous given load, the pressure-operated switch 31 reduces the fan speed to its intermediate value, closes valve 26 and opens valve 25. Again, when the load at intermediate speed decreases a given amount below the previous certain load, the pressure-operated switch 32 puts the fan in its low speed, closes the valve 25 and opens the valve 24. Since the fan takes time to slow down, electric time-delay relays delay the opening of the valve 24, the pressure in pipe 21 being supplied through a bleed 35 to the power device. The relays 16, 17, 18 are such as to produce an output pressure bearing a desirable functional relation to the input pressure in pipes 101 and 11, e.g. a linear relationship which relationship is determined by the shape of a cam 40, Fig. 5. The loading pressure on the diaphragm 19 acts through a spring-loaded member 37, link 38 and lever 39 to position the cam 40 which adjusts through a bell crank 44, 46 the loading of a spring 43 on a lever 41 pivoted at 42. The lever operates a pilot valve 50 supplied with compressed air at S to give an output pressure in the pipes 49, 21, which pressure is led by a pipe 48 to a bellows 47 which acts on the lever 41 to recentre the pilot valve 50. The loading pressure may be supplied to the bellows 47, in which case the output pressure in the pipes 49, 21 acts on the diaphragm 19 to recentre the pilot valve. In the case of the relay 13, a single loading pressure on the diaphragm 20 positions the cams of two relays 17, 18. The solenoid-actuated valves 24, 25, 26 comprise a solenoid 55 |

| 723,540. Fluid-pressure servomotor-control systems. ELECTROFLO METERS CO., Ltd., and ENGLE, F. V. A. E. Dec. 23, 1952 [Sept. 28, 1951], No. 22710/51. Class 135. In fluid-operated automatic control apparatus for regulating a variable condition in which the fluid. pressure in an enclosed space is varied in dependence on the deviation of the variable condition from a predetermined value by means for measuring the actual value of the condition, means for introducing a derivative or " rate of change " action by enhancing the pressure variation in the enclosed space in functional relation with the rate of change of the deviation comprises a substantially freely movable pressure-responsive device such as a diaphragm or piston, which controls a valve device and which is in communication directly with, or is installed essentially within, the enclosed space, the pressure-responsive device and the valve device both being separate from the means which measure the value of the condition. In Fig. 1 compressible medium, such as air, is introduced into the enclosed space 3 through a restricted orifice 3a and passes to a relay or to a regulating device such as a valve or rheostat through a connection 3b. The pressure in the space 3 is regulated by a spring-loaded ball valve 2 operated through a link 1 by means (not shown) responsive to deviations in the variable condition from its predetermined value. The pressure in the space 3 is also regulated by a further spring-loaded ball valve 8 operated by a diaphragm or the like 7 which separates the space 3 from a chamber 4 connected to the space 3 by a passage 5 having adjustable throttling means and/or fixed throttling means 6. A rapid upward movement of the link 1 results in a sudden drop in the pressure in the space 3. Due to the throttling means 6, the pressure changes slowly in the chamber 4 and the valve 8 moves upwardly to increase still further the pressure drop in the chamber 3. Slow change in the position of the link 1 hardly effects the valve 8. In a modification, the ball valve 2 is replaced by flow-restricting device of the " flapper " -or baffle type and this is arranged in series with and on the outlet side of the valve 8. Fig. 3 shows a form suitable for use with liquids under pressure. The pressure in the enclosed space 16 is controlled primarily by a baffle 15 controlling a discharge nozzle 14 in accordance with deviations in the variable condition. The derivative action is introduced by a differential device comprising two spring-loaded pistons 18, 19. The piston 18 is open to the space 16 and provides the seat of a ball valve 20 loaded by a spring 20a which abuts the other piston 19. The annular chamber 21 below the piston 19 is connected to the space 16 through a passage 22 containing a throttling means 23. The valve seat responds rapidly to pressure changes in the space 16 whilst due to the throttling means the piston 19 and therefore the ball valve itself responds slowly. For slow pressure changes in the space 16 the relative positions of the ball valve and its seat remain unchanged. The arrangements in accordance with the invention may be used in conjunction with follow-up apparatus, or stabilizing means adapted to give proportional or integral control or both. Then the discharge nozzle may be carried by a piston actuated by differential pressures which are a function of the distance between the nozzle and the baffle so that the nozzle follows up the movements of the baffle. Specification 723,537 is referred to. | ||||||
