Class 110(iii) [Also in Group XXIX] A gas turbine engine fuel system comprises an engine-driven pump 11 for feeding fuel to burners 14 of the spill type, a servo-actuated throttle valve 17 in the return line 15 from the burners, and a vent valve 27 controlling the throttle valve and actuated in the opening sense by a loading which varies in accordance with engine speed and in the closing sense by a spring 36, a manual control 38, 39 for the spring being operative to select the engine speed at which the vent valve operates to control the throttle valve. The servo-piston 18 which operates the throttle valve is loaded by a spring 23 and is subject on one side to spill line pressure in a chamber 19 and on the other side to pressure in a chamber 20 having a restricted connection 22 with the spill line and the vent connection 25. The vent valve is carried by a differential piston 29 subject to fuel pump delivery pressure in a chamber 30, spill line pressure in a chamber 31, and atmospheric pressure in an intermediate chamber 34, the pressure difference between the chambers 30, 31 varying substantially as engine speed. Instead of the liquid for actuating the servo-piston 18 being derived from the spill line it may be obtained from the pump delivery conduit 13. Also, the differential piston 29 may be subject to the pressure drop across a restriction in the conduit 13 or to the pressure generated by an engine driven centrifuge instead of the pressures in the pump delivery and spill lines.

Abstract: 774,045. Two stable state transistor and discharge tube circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 17, 1955 [May 20, 1954], No. 14200/55. Addition to 722,516. Class 40(6) In a modification of the circuit described in the parent Specification in which a discharge tube is connected in series with the emitter of a transistor, pulses are applied to the control electrode of the tube and the base of the transistor. Positive-going pulses applied to terminals 17, 18, Fig. 1 are differentiated by capacitor 19 and resistor 21, diode. 22 suppressing the positivegoing leading edge so that the negativegoing pulses corresponding to the trailing edge are fed over capacitors 23, 24 to the grid 6 and base. 2b. Assuming the circuit to be on, transistor 2 passes heavy current and the collector potential is relatively high so that tube 1 conducts, maintaining the emitter potential at a high value so that the transistor conducts heavily. The incoming negative pulse applied to the base of transistor 2 is ineffective since the transistor is fully conducting but the pulse applied to grid 6 reduces the cathode current and hence the emitter current, the fall in collector current resulting in a further fall in the grid potential. This process continues until both the devices 1, 2 are to the off state. The next negative pulse is ineffective as applied to the grid 6 since the tube 1 is cut-off but causes the transistor 2' to pass emitter and hence collector current, the rise in collector potential starting the regenerative cycle to set both devices 1, 2 into the on state. The emitter potential is held constant throughout the pulse due to capacitor 26. In a modification Fig. 3 (not shown) a diode is connected in series with resistor 27 to give a more rapid turn on and off. The diode resistor combination can be given a higher reverse resistance and lower forward resistance. In a further modification, Fig. 4, switch 45 may be operated to disconnect the differentiating function. The negative-going edges of the square way are effective to set the circuit from the on to the off state and vice versa. When in the on state the negative pulse is effective at the grid of the tube 32 and in the off state at the base of transistor 2. By employing a resistor 39 a further output may be obtained. A single diode 38 may be used in the emitter lead.
