Class 110(3) [Also in Group XXIX] In the liquid fuel regulating means for gas turbines and other prime movers described in Specification 677,138, means responsive to the difference between the fuel pressures upstream and downstream of the first restricted orifice are provided for proportionately regulating the effective areas of the first and second restricted orifices. In Fig. 1, these orifices are respectively constituted as slots d, e in a cylindrical bore in a body part a having a fuel inlet b from the pump c and a fuel outlet f to the burners. The slots d. e differ in width, the slot d being appropriately wider than the slot e. The slots are regulated by a spring- loaded piston-valve r. The outlet sides of the ports d, e lead through passages q, h respectively to compartments p, i on opposite sides of a diaphragm j. The diaphragm bears a closure member m controlling-an orifice n which leads to a unit o serving to control the output of the pump c or otherwise regulate the liquid fuel supply. The passage and consequently the outlet f are open to the back of the piston r. Fig. 3 Shows a modification in which the fuel inlet b is arranged laterally of the body part a and the outlet to the burner is co-axial with the passage h. The body part has a cylindrical chamber containing a mushroom-like fitting 3 having two rings of ports 4, 5 and a central aperture 6 constituting the second restricted orifice leading to the by-pass passage h. The first 'restricted orifice is formed as a ring of apertures 9 in a slidable disc 7 loaded by a spring such as the resilient ring 8 which also forms a seal.

Title: Improvements in gas turbines for the propulsion of vehicles, particularly locomotives
IPC: F01D1/16
Filed: 1952-01-17
Abstract: 716,811.. Gas turbines. AKTIEBOLAGET GOTAVERKEN. Jan. 17, 1952. [Jan. 23, 1951], No. 1386/52. Class 110(3) [Also in Group XXVII] A gas turbine for the propulsion of vehicles comprises three sections, namely, an impulse stage with a full admission one or more subsequent reaction stages having guide vanes and moving blades with rounded inlet edges and inlet angles so that at starting and slow speeds they essentially correspond to the direction of the absolute inlet velocity of the motive fluid from the preceding vanes and one or more subsequent reaction stages having guide vanes and moving blades with inlet edges which are rounded to a greater radius of curvature than the inlet edges of the preceding reaction blades. The invention is described with reference to a gas turbine plant, Fig. 1, comprising two stroke internal combustion engine 1 feeding a gas turbine 14 through a conduit 10 with combustion gases mixed with scavenging air supplied by a compressor 3. A governor 19 acts on a fuel pump 71 to limit the speed of the engine. The supply of fuel can also be controlled manually by means of a lever 74. An auxiliary control device 75 actuated by the pressure at the discharge of the compressor 3 connects the conduit 10 to an outlet 24 when this pressure falls below a given value. The admission valve 13 to the turbine 14 is controlled by a lever 67. The turbine 14 comprises three sections, Fig. 2, namely, an impulse stage having guide vanes Ao and moving blades Bo, two subsequent reaction-stages A 1  B 1 , A 2  B 2  and four reaction stages A 3  B 3 -A 6  B,. The impulse stage is designed for full admission and the second section or reaction stages A 1  B 1 , A 2  B, are provided with slightly rounded inlet edges and have such inlet angles that at starting or slow speeds they essentially correspond to the absolute inlet velocity of the working fluid leaving the preceding stage. The blade rim B, should have substantially the same diameter as the blade rim B o . The guide vanes and moving blades of the third section A 3  B 3 -A 6  B 6  have considerably rounded inlet edges and are shaped that the smallest inlet losses will occur when the motive fluid has a substantially axial direction of flow. The turbine is so designed that the heat drop across the guide vanes Ao is greater than half the total heat drop in the turbine at starting and at normal speed is less than one half the same heat drop preferably a third. The pressure ratio across these guide vanes at normal speed should be between 0.50 and 0.75. To reduce the losses in the guide vanes and moving blades of the second section which are stated to act, at starting, as velocity stages for the impulse stage and during normal running as reaction stages, the rear portion of the usual profile is cut away, Fig. 3, and the blades have substantially plane rear faces d.

Abstract: 906,156. Control of motors. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 14, 1959 [Jan. 15, 1958], No. 1389/59. Class 38 (3). [Also in Group XXXVIII] To enable a kine projector, coupled for associated working with a tape-recorder, to reach operating speed and synchronism rapidly, a resistor, normally connected in series with the projector motor, is initially short-circuited to provide a higher than normal starting torque. The tape is driven by a capstan 11 and pinchroller 14 forming part of the projector drive and a rocker-mounted roller 7, in known manner, gauges the tape-loop 16 and varies a rheostat 4 connected in series with the projector motor. In the circuit of Fig. 2, the voltage across the motor 13 is rectified by the network 18 to operate the relay 19 via the slugging arrangement 20, 21, 22. The delay in operation of the relay depends inversely on the voltage available across the motor 13 so that after an interval appropriate to the mains voltage available, the relay 19 opens the contact 19 to restore to the circuit the resistors 15, 17. Resistor 15 will normally be present in the projector, 17 can be finely adjusted. The time-constant of the circuit 19, 21, 22 is so arranged as to prevent relaxation oscillations in the control gear.

A seal assembly for maintaining oil about a shaft 16 of, for example, a compressor comprises a chamber 120 for the oil, seals 72, 116 at each end of the chamber, and a dam means (136), Fig. 3 (not shown) which extends into the chamber between the oil inlet and outlet connections 134, 138. The dam means consists of a partition 136 which co-operates with a collar 84 on the shaft to prevent oil from the inlet going directly to the outlet. The seals are in the form of a lipseal 72 which is urged into engagement with the shaft by spring fingers and a face seal 116 which is urged into engagement with the collar 84 by a bellows 112. Oil from a supply pipe 126 fills a chamber 68 and bleeds through an orifice 66 to a bearing 48; the orifice acts to increase the pressure of oil in this chamber 68 and cause the oil to flow past the lip seal 72 into the chamber 120. Upon shutdown, the oil in the chamber 68 drains away and the oil in the chamber 120 is retained by the two seals 72, 116. In another embodiment, Figs. 4 and 5 (not shown), lip seal (220) and face seal (240) retain the oil in the chamber (250). In operation, oil in chamber (250) leaks past the lip seal (220) into another chamber (244) provided with an outlet orifice which controls the pressure drop between the two chambers. Upon shutdown, the oil drains away from the chamber (244) through the orifice and the oil in the chamber (250) is retained by the two seals.
