Abstract: 852,784. Gas turbine plant. BADISCHE ANILIN- & SODA-FABRIK A.G. June 4, 1958 [June 7, 1957], No. 17791/58. Class 110 (3). The rotor 1 of a gas turbine, cooled evaporatively, is supplied with cooling liquid through a non-return valve 19 arranged in parallel with a continuously operating pump 18 conveying part of the liquid evaporated in the rotor. As shown in Fig. 1, the liquid from a feed-pipe 2 enters an axial bore 3 in the rotor shaft 4 and is conveyed, via radial passages 5 in the rotor to a chamber 6 in the latter. Chamber 6 communicates, via bores 8, with a chamber 7 within shaft 4. An axial bore 9 connects chamber 7 with a return-pipe 12. Valves 10, 11 in the return circuit so regulate the pressure in chamber 7 that the latter is filled with vapour while chamber 6 is filled with liquid. The vapour enters a reservoir 13, where droplets of liquid separate out, and is discharged therefrom via a regulating valve 15. Make-up liquid is supplied to reservoir 13 via a pipe 20.. A liquid cooler 17 is interposed between reservoir 13 and pump 18. In a modification, Fig. 2, vapour from pipe 12 is condensed in a heat-exchanger 13 around pipes 21 therein supplied with water by a pipe 22 to maintain a constant level a of cooling water in the heat-exchanger. Steam generated in the latter leaves by a pipe 23. The condensate in the heat-exchanger is maintained at a constant level b by make-up water supplied by a pipe 20.

Abstract: 1,184,543. Automatic temperature control systems. DUNLOP CO. Ltd. April 18, 1967 [April 23, 1966 (2)], Nos. 17856/66 and 17857/66. Heading G3R. A temperature control system for a de-icing heater having a resistance which varies with temperature comprises means for sensing changes in the heater resistance and a control means for reducing the power supplied to prevent the heater temperature rising above a determined level. The heater H is connected to a transformer voltage winding Vw and an opposing current winding I w which at the determined temperature reverse the phase of the secondary winding Sw output which through transistors Q1-Q3 and Q4-Q6, delays the firing angles of thyristors SCR1, 2 in proportion to the excess temperature. An over heat protective circuit, Fig.3, (not shown) comprises a transistor amplifier connected to winding Sw operating a relay which disconnects the supply and illuminates a warning lamp. In another arrangement voltages are derived from a heater having two sections of differing characteristics, Figs. 5 and 6 (not shown). A 3- phase star connected heater arrangement is described having thyristors in two mains leads, Fig. 7 (not shown). The output of winding Sw alternatively can be arranged through a variable ratio timer to cut-off the thyristors periodically for a determined time and an auxiliary circuit is arranged to operate at a higher temperature should the normal circuit fail. A low temperature circuit is also incorporated which at low temperatures periodically interrupts the supply when warming up the heaters. This circuit also incorporates thermistor detectors to cut-off the power at a determined thyristor temperature. An arcing detection circuit may be incorporated comprising three current transformers (T52-T54, Fig. 7, not shown) whose outputs are amplified in transistors (Q52-Q54, Fig. 9, not shown), and compared to cut-off power on inequality of current flow. This circuit is disabled if the inequality is due to an open circuit of one of the heaters.
