Abstract: 1533548 Fluid oscillators PNEUPAC Ltd 31 Oct 1975 [26 Nov 1974] 51223/74 Heading G3H A fluid-pressure actuated oscillator, especially for lung ventilation equipment, comprises a main valve A having a supply port 1, outlet ports 2, 3 and exhaust ports 4, 5, and pilot timer valves B, C for alternately subjecting the opposite ends of the spool of the main valve to pressure fluid thereby repeatedly changing-over the main valve and producing an oscillating output in line O. The main valve is such that both its outlet ports 2, 3 are connected to the supply port 1 in the mid-position of the spool and the spool is subjected to a net axial thrust when equal pressures are applied to both its ends. Thus on cessation of supply pressure the spool is unlikely to stop in the mid-position but if it does then on restoration of supply pressure, normal oscillation of the spool will commence. The net axial thrust on the spool can be produced by  spring biasing or by unequal areas at the spool ends.

Abstract: 1,035,050. Inverting. WESTINGHOUSE ELECTRIC CORPORATION. Dec. 31, 1963 [Jan. 25. 1963], No. 51283/63. Heading H2F. In a parallel inverter in which a commutating capacitor 10 is connected on the secondary side of an output transformer 2, proper shutting off of main inverting thyristers 26, 28, is effected by further thyristors 60, 62, 64, 66. D.C. is supplied through a switch 12 to the parallel inverter and also to square-wave generator 32 from which control pulses are derived through a circuit 30, this circuit 30 supplying two pairs of antiphase pulse windings 38 and 42, 68 and 70 whose pulses are time-delayed by saturable reactors 90, 102. The square-wave generator also supplies undelayed signals on windings 80 and 82. The commutating capacitor 10 in series with an inductor 58 is connected at one end to an end tapping 46 of the transformer secondary winding 6. Its upper end is connected to a tapping 50 via the pair of back-to-back thyristors 64, 66, controlled by the windings 80, 82, and to a tapping 52 via back-to-back thyristors 60, 62 controlled by windings 68, 70. In operation on a positive half cycle of the square wave (shown dotted in transformer 72) winding 80 renders thyristor 64 conducting to discharge capacitor 10 through the lower end of the secondary winding 6. After a time interval dependent on the saturation of reactors 90 and 102 pulses with the polarities shown are derived on windings 38, 42, 68 and 70, those on 42 and 68 being correctly poled to fire thyristors 28 and 60. Current flows in the primary winding 4 producing the voltages shown dotted, and the capacitor 10 charges through the thyristor 60 so that its upper plate is positive. After a predetermined time the charge is sufficient for thyristor 60 to be shut off. Current also flows in the load, the voltage depending on the position of switch 56. Current continues to flow in thyristor 28 until the reversal of the output of square wave generator, when reverse saturation of the reactors 90 and 102 starts. However, there is an immediate signal on the winding 82 rendering thyristor 66 conductive to discharge the capacitor 10 through the lower end of winding 6. This discharge produces a voltage in the primary winding to forwardly bias the diode D2, shutting off the thyristor 28. At the end of the delay time signals are produced on windings 38 and 70 to fire thyristors 26 and 62 and the next half cycle continues in a similar fashion.
