Title: Improvements relating to steam turbines
IPC: F01D25/26
Filed: 1967-04-12
Abstract: 1,145,612. Steam turbines. LICENTIA PATENT-VERWALTUNGS G.m.b.H. April 12, 1967 [April 12, 1966], No.16816/67. Heading F1T. In a steam turbine, relative axial expansion between an outer casing and an inner casing supporting the stator blading is permitted by expansion members each comprising an axially extending tube rigidly connected at one end to the inner casing and connected at the other end with axial clearance to a bushing secured to the outer casing, the tubes being forced with ports for the circulation of hot steam through them. The inner casing 1 supporting stator blading of a steam turbine is connected to an outer casing 2 by axially extending tubes 3 which permit relative axial expansion between the two casings. The tubes 3 are provided with ports 6, 7 for heating by steam whereby their resultant thermal expansion minimizes the relative axial displacement of the rotor and the inner casing. In the case of an L.P. stage comprising three L. P. sections in separate casings, the first section, i.e., the section adjacent the thrust bearing, has its inner casing connected to its outer casing by heated tubes as above, and similar heated tubes are used to connect the inner casing of the second section to the inner casings of the first and third sections. This ensures that the relative axial displacement between the rotor blading and stator blading due to thermal expansion remains almost constant over the length of the entire rotor.

Abstract: 355,387. Rectilinear-motion bearings. FEREDAY, H. J., 22, Huron Road, Upper Tooting, London. June 2, 1930, No. 17001. [Class 12 (i).] Fluid under pressure is admitted to and retained in a cavity between the opposed surfaces of bodies capable of relative rectilinear movement to reduce the force of friction therebetween. As shown for a hydraulic jack pressure fluid is admitted to a cavity 2 in the base of the jack by opening a valve 8 and the jack can then be easily traversed by actuation of a screw 12 or otherwise. Packing 3 prevents leakage of the pressure fluid and packing 17 prevents foreign matter from entering between the rubbing parts. The passages 7a leading the fluid from the interior 1 of the jack to the cavity 2 may have a valve arranged so that the pressure of the fluid in the cavity 2 may be released to restore the pressure between the base of the jack and its support 11 to normal when desired. The fluid admitted to the cavity 2 may be supplied from an independent source and the jack may be traversed by hydraulically or mechanically operated means.

Title: Improvements in or relating to electric control systems
IPC: H02P23/00
Filed: 1959-05-20
Abstract: 877,440. Automatic speed control systems. WESTINGHOUSE ELECTRIC CORPORATION. May 20, 1959 [May 26, 1958], No. 17137/59. Class 38 (4). In an automatic speed control system for a prime-mover driving an alternator, the throttle is controlled by an electromagnetic arrangement, the energization of which is derived through a magnetic amplifier controlled in dependence on the alternator frequency, throttle position and the rate of change of throttle position. As shown, a three-phase star-connected alternator G is driven by an engine E controlled by a throttle T. A frequency inverter FI, comprising transistors TR1, TR2 is fed from the alternator through a transformer T2 and a rectifier CR2. The alternating output of the inverter energizes a solenoid 14 through windings 13, 18 of a magnetic amplifier MA1 and a solenoid 16 through windings 15, 19 of a magnetic amplifier MA2. Variation in the energization of control windings of the magnetic amplifiers MA1, MA2 causes the solenoids 14, 16 to be differentially energized to vary the bleed from a double-acting piston valve C7 and displace a piston P mechanically coupled to the throttle T. A secondary of a transformer T1, energized from a phase 3P, feeds a resistor 19 through a frequency selective network L, C3, C4 and a rectifier CR3. The network is arranged so that the voltage across the resistor R19 is proportional to frequency for a range centred on the desired frequency. A resistor R7 and a rheostat R9 are fed from the phase BP through a resistor R10 and a rectifier R10 to derive a reference voltage opposing the frequency-dependent voltage across resistor R19. The difference voltage feeds control windings 41-44 of magnetic amplifiers MA1, MA2 so as to maintain the engine speed constant. The speed is adjusted by rheostat R7 and the control winding current by a rheostat R18. Bias windings 31, 32, 37, 38 are energized through a rectifier CR1 from the phase 3P. The current balance between the magnetic amplifiers MA1, MAS is adjusted by a rheostat R11 and the total current by a rheostat R12. A throttle operating lever LK is coupled to a throttle position feedback potentiometer R13 and the voltage difference between a slider 64 and a slider 57 of a reference potentiometer R14 energizes control windings 59-62 on the magnetic amplifiers MA1, MA2. A parallel combination of a rheostat R17 and a capacitor C9 in series with a rheostat R16 is arranged so that the current through the control windings 59-62 is also dependent on the rate-of-change of throttle position. The sensitivity is adjusted by the rheostat R16. Transient signals of large amplitude are by-passed by a rheostat R15 and semi-conductor diodes D1, D2. For parallel operation between similar alternators, windings 75-78 and windings 275-278 are energized by the difference between voltages representative of the positions of the throttles derived from potentiometers R28, R8.
