In a gas turbine power plant comprising two gas turbines, the smaller is employed for starting the larger and provides a heat source for preheating the power plant before the larger unit is started up. An auxiliary gas turbine 8 drives a main turbine 3 through a gear train 9 and clutch 10 for starting purposes and the main turbine drives a generator 4. The exhaust from the turbine 8 is mixed with air in a mixing device or injector 11 and the mixture is used to heat up the space containing the power plant. The mixture passes into the intake of the compressor 1 and pre-heats the main turbine or a heat exchanger may replace the mixing device 11 so that exhaust gases do not pass into the intake of compressor 6. In another embodiment, Fig. 3, the smaller turbine drives an auxiliary generator 16 through a centrifugal clutch 15. The smaller turbine is first started to provide a supply of heat through heat exchangers 12, 14 for the power plant. When the generator 16 is clutched in current is available for the entire installation including the main turbine auxiliary services and when the power plant has warmed up sufficiently, the clutch 10 is engaged to rotate the main turbine. A valve 13 controls the supply of exhaust gases to the heat exchangers. When the main turbine is sufficiently warm, the gases in the combustion chamber 2 are ignited and the plant can run normally.

Title: Improvements in the purification of organic bodies by distillation
Filed: 1920-04-24
Abstract: The separation of the constitutents of mixtures such as crude resorcinol, crude anthracene cake, crude anthraquinone, &c., is effected by distilling the substance with a mineral oil, such as kerosine, fuel oil, &c., containing fractions which boil within wide limits.  The constituents of the mixture distil over with the oil at different stages and are collected separately. Alternatively, a mineral oil fraction having a boiling point above that of any of the constituents of the mixture to be separated, is used.  The mixture is heated and, at various stages in the rise of temperature, steam is passed through the mixture to carry off the constituents separately in the order of their volatility.  In treating crude anthracene cake, carbazole passes over first, then anthracene and finally phenanthrene.
