Abstract: 824,292. Valves. ROSS OPERATING VALVE CO. March 8, 1956 [March 18, 1955], No. 7291/56. Class 135. A fluid-actuated valve adapted to be actuated alternately between an exhaust position and a supply position by successive movements of a pilot valve member comprises a spool 13 slidable in a housing 11 between the two alternate positions and having pistons 14, 15 of unequal area slidable in chambers 16, 17 between which is an intermediate chamber 23 which can be connected with a source of pressure or with exhaust by valve means 29, 31 carried by the spool. A detent 59 co-operable with a shoulder 61 on the spool is arranged coaxially with a pilot valve 42 for connecting the chamber 16 with the chamber 23. The chamber 17 which is formed in an insert 18 is permanently connected with a source of pressure 19 through a port 21. The chamber 23 is connected through a passage 28 controlled by a valve ring 31 with an exhaust port 27. An adjacent valve ring 29 controls the connection between the chambers 17 and 23. The chamber 23 is in communication with the chamber 16 through passages 49, 51, 52, 53, 54, the passage 52 being provided between a valve spool 42 having sealing rings 46, 47, and an intermediate valve ring 48. On energization of a solenoid 12 by closure of a switch 65 the pilot valve spool 42 is depressed and the ring 48 disconnects passages 52 and 53 from one another so that the chamber 16 is isolated. The detent 59 is mounted in a guide 57 itself mounted in an insert 58. The guide has extensions 63, 64, Fig. 3, which straddle the intermediate part of the spool 13 and is operated against a spring 62 on depression of the spool 42. The chamber 23 is connected by a port 25 to a fluid-actuated device 24. Endwise movements of the spool 13 are limited by members 37, 38 of shock-absorbing material backed by caps 35, 36, respectively. On momentarily energizing the solenoid 12 the detent 59 is released and the spool 13 is moved to the left under the pressure in the chamber 17. The device 24 and the passage 49 are thereupon connected to the pressure supply. On release of the switch 65, the detent 59 rises and engages the right hand side of shoulder 61, and the valve ring 48 rises so that the chamber 16 also is connected with the supply pressure, the chamber 23 being cut off from the exhaust port 27 by the valve ring 31. On the next momentary energization of the solenoid, the detent 59 is released as before and the supply pressure acting on the larger area of the piston 14 moves the spool 13 to the right. On release of the switch 65 the detent 59 is re-set in the position shown in Fig. 1 and the chamber 16 is connected with the exhaust port 27 via the pilot valve spool 42 and the chamber 23 and the differential pressure for moving the spool 13 to the left again is available when the detent 59 is again released.

Abstract: 1420645 Tuning circuits INTERNATIONAL STANDARD ELECTRIC CORP 15 Feb 1973 [18 Feb 1972] 7433/73 Heading H3Q In a tuning circuit having a tuning potentiometer R2 whose wiper is arranged to feed a tuning voltage UD to a varactor diode, first trimmer potentiometer R3 is connected to one end of the tuning potentiometer and a second trimmer potentiometer R1 is connected to the other end of the tuning potentiometer and a resistor R4 is connected in parallel with the series arrangement of the tuning potentiometer R2 and at least one of the trimmer potentiometers. The resistance values are chosen so that with the circuit connected as a potential divider network the curve #f=F(f), Fig. 3, for alignment by means of one of the trimmer potentiometers R3 or R1 goes through zero at a point lying at the high frequency end or low frequency end or both ends of the circuits tuning range, where f is the angular or received fre quency and #f is the frequency change caused by the associated potentiometer R3 or R1. As shown R1 is used to provide adjustment at the low frequency end a of the tuning range. At the high frequency end of the tuning range the frequency adjustment #f provided by R1 is reduced and is zero at the end b of the tuning range. Adjustment at the high frequency end is provided by R3. A further potentiometer R5 may be connected in parallel with the tuning potentiometer R2 so as to enable agreement of the tuning with the scale or setting to midscale. The connections of R1 and R3 may be interchanged (Figs. 3d and 3e, not shown) so that R3 provides zero frequency change when adjusted at the low frequency end of the range. In a modified arrangement (Figs. 4a and 4b, not shown) both R1 and R3 provide zero frequency change at the high and low frequency ends of the tuning range respectively and may be used to adjust the frequency at the low and high frequency ends of the tuning range. The midscale correction provided by the potentiometer R5 may be provided by an inductance having a displaceable core.
