Abstract: 1,120,088. Control of A.C. motors; A.C. generators. MOSKOVSKY ORDENA LENINA ENERGETICHESKY INSTITUT. 22 Dec., 1966, No. 57365/66. Headings H2A and H2J. A synchronous generator 5 supplying A.C. traction motors 6 is driven by a gas turbine 4 forming part of a set which comprises compressor 2 which is driven at a selected speed by turbine 3. A field winding 7 of the generator is supplied through rectifier 8 from magnetic amplifier 9 having control windings 14, 15, opposed by control winding 16. The winding 14 is energized through choke 17 and rectifier 18 in accordance with the output voltage of the generator 5, the winding 15 being supplied from a unit 19 which compares the generator voltage with a reference signal derived from the set 1. The winding 16 also receives this signal. Braking resistors 22 are connectable to the traction motors through contactors 21. Over a lower range of frequencies, the winding 14 is effective so that the output voltage of the generator 5 is substantially proportional to the frequency. Over a higher range, the generator voltage applied to the comparator 19 overcomes a bias or Zener diode voltage, whereby winding 15 is energized to reduce the rate of increase of voltage with regard to frequency. Over a still higher range, the winding 14 is energized from a supplementary circuit comprising a resistor and a rectifier in series with rectifiers 18 to provide a constant voltage output. The winding 16 may be supplied through a tuned circuit from an A.C. tachometer generator through a diode and a potentiometer which is connected to a source of constant voltage. Alternatively, the control winding 16 is energized in accordance with the output of a transducer for converting movement of a fuel supply mechanism into an electrical signal. In another arrangement, the winding 7 is supplied from an exciter whose field winding is connected to the output of rectifier 8. The latter may comprise a diode bridge or thyristors. The magnetic amplifier 9 can be provided with stabilizing windings receiving signals from the field winding 7 through a capacitor or transformer.

Abstract: In the gasification of fine-grained solid or liquid fuel with oxygen under overpressure, fine-grained iron oxide- containing material is supplied to the gasification zone for controlling the temperature in the gasification zone to a temperature between 1300 DEG and 1700 DEG C. The reaction products from the gasification are caused to flow immediately after the gasification zone through a layer of pieces of coke having such a depth in the direction of gas flow that the solid and liquid reaction products in the gas are separated out onto the coke. By-product crude iron and slag formed in the process are tapped from a low level in the coke layer and gas is discharged from the coke layer at a higher level. The gas discharged from the coke layer may be utilised for generation of electricity in a combined gas-stream turbine system. <IMAGE>

Abstract: A drive device for imparting consecutive feed movements at two different speeds to a slide comprises a spindle and nut gearing 19; 9 of which the nut 9 carries the slide and the spindle 19 is driven, for rapid feed of the slide, by a hydraulically operated pawl and ratchet wheel mechanism 12;4. A first helical gear 5 is secured to the ratchet wheel 4 and meshes with a second helical gear 6 which has a braking cone 14 and which is guided freely rotatable and axially slidable on a rod 7 operatively connected to a first hydraulic cylinder 1. The helical gear 6 with the braking cone 14 is urged into the braking position by means of a compression spring 15 and the brake is released by means of the rod 7 upon actuation of the cylinder 1 by a working fluid. The actuation of cylinder 1 also causes a connecting pipe 17 for the working fluid to be opened in order to actuate a second hydraulic cylinder 2 operatively connected to a push rod 18 on which the pawl 12 is pivotably mounted. The actuation of cylinder 2 causes the spindle 19 to be driven via the pawl and ratchet wheel mechanism and the slide to be moved at rapid feed. On completion of the rapid feed the two hydraulic cylinders 1;2 are de- pressurised whereby the brake 14 is applied to the ratchet wheel 4 and the push rod 18 is returned to its initial position by the action of respective springs 15;21, whereupon the thrust piston drive 11 is actuated to rotate the nut 9 and impart a slow feed to the slide. <IMAGE>
