Title: Regulating means for combined-cycle gas turbine and steam-turbine plant
IPC: F01K23/06
Filed: 1961-09-27
Abstract: 987,436. Combined steam and gas turbine plant. STEIN & ROUBAIX. Sept. 27, 1961 [Nov. 8, 1960], No. 34729/6l Headings F1Q and FIT. A combined-cycle steam and gas turbine plant in which a steam boiler feeds a steam turbine and the combustion gases from which are supplied to a gas turbine driving a compressor which supplies pressure air to the boiler combustion chamber, has a convective heat exchange for superheating or reheating the steam and three paths from the compressor to the gas turbine, the first through the boiler, the second through an auxiliary furnace and the third through a by-pass and means for controlling the distribution of air between the three paths, the temperature of the superheated or resuperheated steam being controlled by varying the excess air supplied to the boiler by the first path and the temperature of the gases entering the gas turbine being controlled by varying the distribution of air between the second and third paths. Air from the compressor 1 is divided into three streams A 1 , A 2 , A 3 . The stream A, enters the boiler 2 where it supports the combustion of fuel C 1 . The stream A 2  is fed to the auxiliary furnace 17 where it supports the combustion of additional fuel C 2 . The furnace 17 may be provided with cooling means. The stream A 3  dilutes the gases leaving the boiler 2. The amount of fuel C 1  is controlled to maintain the steam pressure constant. The control of the superheated or resuperheated steam temperature is controlled by varying the amount of excess air by controlling the air supply A 1 . The gas turbine inlet temperature is controlled by varying the fuel supply C 2 . To vary the distribution of air it is sufficient to act upon two streams. In the arrangement shown the streams A 2 , A 3  are controlled by valves 19, 20. In the case of a resuperheating cycle, the temperature of the resuperheated steam may be controlled by regulating the air stream A 1  and the temperature of the superheated steam by any other means e.g. by injection of water. In a modification Fig. 3 (not shown) the superheater and resuperheater are arranged in separate enclosures each of which has a controlled supply of air and fuel.

IPC: F24H1/44
Filed: 1937-12-23
Abstract: 507,615. Controlling combustion. CROMPTON. C. E. Dec. 23, 1937, No. 35571. [Class 51 (i)] [Also in Group XIII] Steam or hot-water boilers comprise two independently fired boilers combined in a single unit, a main shell type boiler A fired with solid fuel and an auxiliary oil or gas fired shell type boiler C supported on the main boiler shell by branch pipes B communicating with the steam and water spaces of the two boilers. The supply of fuel to the auxiliary boiler is controlled in dependence on the temperature or pressure within the main boiler. The rise of steam pressure above a predetermined level effects the closing of a pilot valve F in gas piping F<1>, F<2> opening below the boiler, and the consequent closure by the gas pressure produced, of a main gas control valve F<3>. A fall of water level also effects this result by means of a float-operated valve F<4> in the gas piping. The auxiliary boiler may be used for night duty and cut out during the day or it may augment the main boiler during periods of exceptional demand.

Title: Apparatus for the rolling of continuous strip iron
IPC: B21C37/16
Filed: 1954-12-14
Abstract: 762,268. Rolling; making tubes. BENTLER-WERKE AKT.-GES. WERK NEUHAUS. Dec. 14, 1954 [Dec. 17, 1953], No. 36218/54. Classes 83 (2) and 83 (4). Continuous iron strip, having one plane surface A, Fig. 12, and one profiled surface B giving variable thickness in the longitudinal direction for the manufacture of constructional tubing C which is externally cylindrical but of varying thickness, is made in a rolling mill having a largerdiameter roll 2 that serves as a substantially plane support surface and a smaller-diameter roll 5 that is automatically adjustable to and from the larger roll during the rolling process ; the larger roll has a diameter three or four times that of the smaller roll. The smaller roll, which may be freely rotatable or be driven at the same peripheral speed as the larger roll, is carried at each end in arms 8 rotatably connected to the outer sleeves of double eccentrics 10 which are adjustable to vary the roll stroke. The inner eccentric sleeves are carried by a shaft 12 driven with a 2: 1 gear ratio by a shaft 15 having a four-arm Geneva Cross 15 by which it is rotated intermittently by a pin disc 16 on a sleeve 18. The sleeve 18 encloses a shaft geared to the roll drive-shaft 3 and can be coupled to the shaft 19 by an electromagnetic clutch 20. A rotary switch disc 29 is driven by infinitelyvariable gearing 26 from the roll drive shaft and has a contact 29 engageable with one or other of two contacts 31 adjustably spaced on a fixed disc 34. When the contact 29 engages one of the contacts 31, a relay is operated and a holding circuit is established through a switch 24 controlled by a cam disc 23 on the sleeve 18. Closing of the relay releases an electromagnetic brake 38 and energizes the clutch 20 so that the Geneva Cross 15 is rotated by a quarter turn. Through the 2: 1 gearing, the eccentrics are rotated by a half turn to raise the smaller roll by the maximum adjusted amount. After one complete revolution of the pin disc 16, the switch 24 is opened by the cam disc 23 and the clutch 20 is de-energized and the brake 38 energized. When the contact 30 engages the other one of the contacts 31, the relay is again operated and the pin disc 16 is rotated through a further complete revolution to restore the eccentrics and the smaller roll to their original positions. This method of operation gives the form of sheet used for the tube shown in Fig. 12 but by continuous rotation of the eccentrics a continuous cyclic variation may be obtained.
