The invention relates to a multi-stage steam turbine plant in which steam is reheated between turbine stages by means of steam bled from the turbine. The plant shown comprises a high pressure turbine stage 11, an intermediate pressure turbine stage 12 and a low pressure turbine stage 13, steam from a steam generator being supplied to the high pressure turbine 11 through line 14, and the steam from the high pressure turbine passing to the intermediate pressure turbine through line 15, additional live steam from the steam generator being supplied to the line 15 through line 16. The pressure of the live steam in line 16 is of course less than that of the live steam in line 14. Steam from the outlet of the intermediate pressure turbine passes through line 17 to the inter-stage reheater 18A, the reheated steam passing through line 19 to the inlet of the low pressure turbine 13. The steam is reheated in the reheater by means of steam bled from the H. P. and I. P. turbines at points 43, 44, 45, the steam from these points passing through lines 40, 41, 42 to heating coils 46, 47, 48, all respectively, in the reheater. Steam discharges from the coil 46 to a flashbox 49 the steam from which passes to the line 41 and thence through the coil 47. Similarly, steam discharges from the coil 47 to a flashbox 50, the steam from which passes to the line 42 and thence through the coil 48. Steam discharging from the coil 48 passes to a feed water heater 25 which contains a coil 26 through which feed water flows from inlet 28A to outlet 26B and so back to the steam generator. Water from the flashboxes 49, 50 passes to the feed water heater 25, the water from the heater passing through line 27 to the condenser.

Abstract: 935,585. Pump motors. ALLIS-CHALMERS MANUFACTURING CO. July 24, 1962 [Aug. 3, 1961], No. 28482/62. Class 35. A " canned " electric motor and pump unit has a restricted passage limiting the flow of liquid from the pump to the rotor chamber so that in operation, substantially all the liquid passing through the restricted passage into the rotor chamber is vaporized by the heat generated by the motor. In Fig. 1, a motor 11 drives a centrifugal pump 14, the shaft 12 being common to both units. The motor housing includes a pair of annular end covers 19, a yoke 16, and a cylindrical stator core which is sealed at both ends by 0-rings 22. The rotor 18 is encased in a can 24 to protect the windings from liquid in the rotor chamber 21. The shaft bearings 38, 39 are mounted in supports 30, 35 and are lubricated by the liquid being pumped, bearing 38 by conduit 40 and bearing 39 by pipe 41, the amount of lubricant being controlled by valve 48. The return flow for the lubricant is down the hollow shaft and into the low pressure side of the pump. The amount of liquid in the rotor chamber is restricted by bushings 50 which rotate with shaft 12 and also serve as flame path retarding bushing. In operation the small amount of liquid which leaks into the rotor chamber is vaporized by heat and assists in pressurizing the rotor chamber tending to prevent further flow of liquid and the rotor then revalves in a gas rather than a liquid, thus cutting down energy losses. The motor may have only one bearing.
