Title: Combined steam turbine and gas turbine power plant
IPC: F01K13/02
Filed: 1974-07-17
Abstract: 1473413 Turbine power plant GENERAL ELECTRIC CO 17 July 1974 [17 Sept 1973] 31709/74 Heading F1Q [Also in Division G3] A power plant comprises, Fig. 1, at least one gas turbine 9 the exhaust gases of which pass through a steam generator 35 supplying steam to a header 5 and thence via control valve 31 to a steam turbine 6, a control system 25 being arranged to maintain the steam pressure in header 5 at one of a number of set levels by operating valve 31 and including means to change from one set level to another in response to the position of the valve. In the plant shown there are two gas turbines 9 each having an associated compressor 7 and combustion chamber 8, and driving respective electric generators 10, 11. Transducers 15, 16 transmit signals representative of the output of the latter to respective gas turbine control systems 17. The latter are supervised by a combined plant control system 18 which receives from transducer 34 signals representative of the output of steam turbine driven electric generator 22 and assigns to the individual systems 17 load settings for the respective gas turbines in order to meet the total plant demand set by knob 19. Steam turbine control system 25 is independent of control systems 17, 18 and acts on admission valve 31 and on a by-pass valve control system 26 in response to shaft speed, steam header pressure, turbine casing temperature and degree of opening of valve 31 as detected by sensors 27, 28, 29, 30 respectively. Fig. 4 shows a block diagram of the control system 25, the two basic modes of operation involving the start-up speed and load control subsystem 60 and the steam header pressure control sub-system 61. Sub-systems 60, 61 limit the position of valve 31 which is otherwise at all times regulated by speed control sub-system 62. Subsystem 61 includes logic circuitry 77 for forming the pressure level setpoint of header 5. Circuitry 77, illustrated in greater detail in Fig. 5 (not shown), receives from sensor 30 first and second trigger signals when valve 31 respectively exceeds 95% or is less than 70% fully open. The circuitry 77 also receives signals 86, 87, 88, 89 representative respectively of turbine temperature, a manually set header pressure, operation of supplementary burners 41 in the steam generators 35, and synchronization of generator 22 to the line. Once circuitry 77 has determined a given pressure setpoint for header 5 that set-point is maintained so long as valve 31 is between 70% and 95% fully open. If the latter opening is exceeded, the circuitry increases the setpoint to the next higher value and valve 31 closes slightly, Figs. 6, 8 (not shown). Similarly if the valve opening falls below 70%, the setpoint is decreased to the next lower value and the valve opens slightly, Figs. 7, 8 (not shown). Temperature signal 86 determines the rate at which the setpoint is changed from one level to the next. Though only two gas turbines have been shown, there may be up to six gas turbines associated with a single steam turbine.

Title: Mechanism for converting continuous into intermittent motion
IPC: F16H29/02
Filed: 1955-11-07
Abstract: 795,623. Gearing for conveying rotary motion. GOLDING, W. F. Nov. 5, 1956 [Nov. 7, 1955], No. 31764/55. Class 80 (1). Gearing for converting continuous rotary motion of a shaft 2 into intermittent rotary motion of a shaft 21, particularly for feeding sheets in a cutting, creasing and embossing press by means of a chain 23 driven by a sprocket 22 on the shaft 21, comprises a slide member 7 which is reciprocated in a guide 8 by a crank 3 and connecting rod 5, a chain sprocket 10 rotatably mounted on the slide 7 and engaging at diametrically opposite points with straight runs 14, 16 of chains 13, 15 respectively. The chain 15 passes over a sprocket 20 on the shaft 21, guide sprockets 17, 19 and a sprocket 18. The chain 13 passes over sprockets 11, 12 and constitutes an idle chain. Secured to the sprockets 12, 18 are discs 35, 36 with notches 37, 72 and 38, 73 respectively. These notches co-operate with dogs and pawls 39, 39a and 40, 74 respectively which are carried on the arms of a rocking member 33 pivoted at 34. This rocker 33 is controlled by two cams 29, 30 on the driving- shaft 2 acting on rollers 31, 32 to lock alternately the disc 35 and 36 for each stroke of the slide 7. The chains 13 and 15 are thus alternately stopped and driven. When the idle chain 13 is stopped on the upward stroke of slide 7 the driving sprocket 10 runs along it as a rack to drive the chain 15 at twice the speed of the slide to drive the shaft 21. On the downward stroke of the slide the chain 15 and hence the driven shaft 21 is held whilst the chain 13 is driven idly. Thus the shaft 21 is driven intermittently during each half revolution of the driving shaft 2. A valve controlled dashpot 53 is provided to reduce the momentum of the chains 15 and 23 and their associated parts at the end of each movement. A similar momentum reducing device 66 at the other end of the chain 23 may act through a brake 63. In a modified arrangement the end sprockets of the chains 13 and 15 are arranged on diametrically opposite sides of the driving shaft 2 and provided with discs having arcuate grooves in the faces thereof which co-operate with an arcuate lug on a disc on the driving shaft so that each chain is locked alternately for a half revolution while the other is driven.

Abstract: 1,196,794. Laminated webs. GLANZSTOFF A.G. 11 July, 1967 [14 July, 1966; 17 Dec. 1966], No. 31844/67. Heading B5N. In a process for the manufacture of a web of material which is strengthened with an array of intersecting threads, a group of transverse threads is deposited by thread guides on a rotating thread laying device so that the transverse threads extend between two pin-carrying chains and are supported by the pins 17, Fig. 2, thereof, the chains running parallel to one another in a layer zone containing the thread guides, the group of transverse threads is continuously brought to an assembly position where it is assembled with a group of longitudinal threads 12, the assembly of transverse and longitudinal threads is guided between two webs of material and secured thereto, and the group of transverse threads is removed from the pins of the pin-carrying chains. The webs may be of plastics, paper, or fleece. In one embodiment of apparatus for carrying out the process, Fig. 4. threads 37 from spools 36 mounted on a turntable 35 are led to thread guide eyes 41 on adjustable arms 51 which rotate to wind the threads on to the pins of parallel pin-carrying chains 42, 43, so that the threads extend between the chains and transversely of their motion to pressure rollers 28, 29. Longitudinal threads 32, foil 21 and adhesive coated foil 22 are also fed to the pressure rolls to form a laminate after which the edges of the laminate are trimmed and it is wound on to a roll 49. The winding of the threads on to the pins of the chains is so arranged that each thread is looped about a single pin on one chain and several pins on the other depending upon the number of supply spools. In further embodiments of apparatus the arrangement of the pincarrying chains may be varied, and more than one spool-carrying turntable may be present. When it is desired to make the spacing of the transverse threads in the finished laminate different from the spacing of the threads when on the pin-carrying chains the pressure rollers, material webs, and longitudinal threads are moved more quickly or more slowly than the chains. In this case one of the pressure rollers may he provided at its ends with toothed wheels or rubber rings which maintain the threads in the required positions between the webs. In a further embodiment the transverse threads may be disposed obliquely and intersect each other.

Title: Improvements in or relating to electrical circuit means employing transistors
IPC: H03G3/30
Filed: 1956-10-22
Abstract: 840,976. Transistor automatic gain control circuits. PHILCO CORPORATION. Oct. 22, 1956 [Oct. 20, 1955], No. 32108/56. Class 40(6). A base input transistor amplifier is controlled in gain by applying an automatic gain control voltage to the base to vary the D.C. current through a non- linear impedance connected in the emitter circuit and arranged to carry the both signal and D.C. components of the emitter collector current. The Figure shows a radio receiver comprising a transistor R.F. amplifier 70 having a diode 84 connected in series with the emitter circuit. The capacitor 110 of the input tuned circuit is chosen so that the apparent source impedance of the input signals is equal to or slightly less than the input impedance of the transistor so that approximately optimum power transfer takes place. As the input signal increases the collector voltage of the second detector transistor 40 becomes more positive and this voltage is applied through the AGC line 30 to the base of the transistor 70. The base to emitter impedance and the impedance of the diode 84 accordingly rise causing an increase in input impedance of the transistor circuit and thus a reduction in the power transfer from the aerial circuit so that the output of the transistor remains more nearly constant. A capacitor 94 connected between the base and emitter of the transistor 70 reduces the initial input impedance of the transistor circuit and accordingly causes the change in input impedance with changes in AGC potential to increase. Diode 84 may be replaced by a thermistor. The AGC arrangement may be applied to an IF amplifier or to regenerative or super regenerative amplifiers. The # network in the aerial input circuit may be replaced by a T-network or a transformer.
