Title: Improvements relating to flowmeters
IPC: G01F1/22
Filed: 1962-09-05
Abstract: 946,274. Fluid-pressure servomotor systems. WALLACE & TIERNAN Inc. Sept. 5, 1962 [Sept. 7, 1961], No. 34053/62. Heading G3P. Also in Division G1] Apparatus for transmitting an indication of the position of the float of a variable-area flow meter 10 has a rod 10 of magnetic material carried by the float 15 so that it travels on a vertical path in a tube 20 between a pair of similar magnets 23 and 24 each pivotally mounted beside, and transverse to, the said path with like poles opposed so that the mutual repulsion of the magnets away from the path varies according to the length of the rod 19 between them and they can be connected to an indicator which shows the float position according to their movements towards and from the path. The magnets are linked to a needlevalve 30 so that when movement of the magnets towards the path the needle valve, released of pressure from a reservoir at 48a operates a pointer 116 on a scale 115 or a gauge 120, both calibrated to read rate of flow through the flowmeter 10 in accordance with the position of the float 15. The magnets 23 and 24 are pivoted on a common supporting structure 22 which, whenever the rod 19 causes the magnets to move, moves in the opposite direction and thereby restores the rod and the magnets to their former relative positions. A slide-valve mechanism 60, 61 with a spool 7 which is attached to a diaphragm 52 moved against a restoring spring 73 by pressure variations caused by the magnets in a space 44 controls the admission of pneumatic pressure to a servo 70. The servo has a hollow cylinder 73 sliding against the force of a tension spring 76 in a cylinder 72 to which it is connected by a rolling seal 75. The cylinder 73 carries a pointer 116 and a fixed guide roller 81 which bears on a guide surface 83. A bell crank lever 87 pivoted to the cylinder 73 at 85 and connected to the link 48 on the moving structure 22 carries a roller 88 which is urged by a spring 92 against a cam surface 89 of a member 90. The cam 89 is cut to a contour which permits the movements of the piston 73 and pointer 116 to be proportional to changes in flow in the meter whilst those of the structure 20 follow the actual displacements of the float 15 which are non linear with respect to flow. Adjustments are provided for the valve spring 53 at 54, 55 for the piston spring 76 at 78 and for the cam plate 90 at 121, 122.

Title: Improvements in fluid pressure actuated mechanism
IPC: F01L15/10
Filed: 1921-12-22
Abstract: 195,151. Schofield, S., and Moreland, T. Dec. 22, 1921. Fluid-actuated gears ; slide valves, cylindrical and piston ; beat or lift valves.-The cylinder has inlet and exhaust ports controlled by the main piston which contains a fluid-actuated, coaxial, combined inlet and exhaust lift valve or a combined lift and piston valve, to put the cylinder ends, alternately, into communication with piston recesses which in turn register with the inlet and exhaust port respectively. The fluid-pressure on the side of the piston is balanced, the cylinder exhaust ports are opened before the ends of the stroke, the cylinder ends are supplied with pressure-fluid when the stroke is abnormal, and the pressure-fluid is worked expansively. The piston is built up of coaxial parts, 4, 5, 5a, 6 secured together by studs and screws, and houses a twopart partitioned valve provided with coaxial seats at each end 21, 21<a>, 23, 23a. Fluid enters at 2, 2a and passes through ports 11, 15, 19, 27 and 14 to the left of the piston, or through ports 11<a>, 15<a>, 20, 26, 14<a> and 8 to the right of the piston. The piston edges Z, X cut off the supply. The exhaust takes place through ports 8, 14<a>, chamber 18, and ports 18<a>, 16, 12 and 3 from the right of the piston or through ports 14, chamber 17, and ports 17<a>, 16<a>, 12<a> and 3<a> from the left of the piston. The piston edges W, Y close the exhaust to provide cushioning. In a modification, a central, compound double-beat valve controls the communication between central and end piston chambers, connected to the exhaust and inlet respectively, and intervening chambers communicating with the cylinder ends. Grooves towards the cylinder ends by-pass steam when the normal stroke is exceeded. In a second modification, the valve has three collars which slide in the walls between the piston chambers, and shoulders which enter recesses and engage seats. The fall of pressure on one end of the valve resulting from the piston overrunning the main exhaust enables the pressure-fluid acting on the other end of the valve, to effect its reversal. In a further modification, the piston is provided with fine compartments wherein a central chamber serves as exhaust chamber for both ends. In this construction expanding steam is taken from one, cylinder end to the other to cushion the piston.
