Abstract: A turbo-machine plant comprises a gas turbine connected to a synchronous electrical machine by way of an over-riding clutch and a compressor connected to the electrical machine by way of a disconnectible coupling. The machine group is operable in two different modes. In one mode, the electrical machine functions as a motor for driving the compressor which delivers air to an air storage chamber and the gas turbine is automatically disconnected from the electrical machine by the over-riding clutch. To change over to the other operational mode the power absorption of the compressor is first reduced to a low level, and the gas turbine is then brought up to synchronous speed and becomes coupled to the electrical machine which then operates for current generation.

Abstract: A stationary gas turbine plant in which a bearing for the bladed rotor is located at the exhaust end of the casing where the flow passage for the exhaust gas merges into an annular diffusor ring surrounding the bearing housing and which is established by radially spaced circular walls interconnected by means of an array of circumferentially spaced radially extending aero-foil shaped ribs. Two of these ribs extending divergently in a generally downward direction toward the foundation for the turbine are made hollow for the purpose of passing support struts through them, the upper ends of these struts being secured to the bearing housing and the lower ends of the struts being secured to the foundation. Additional supports are provided at opposite sides of the casing at the exhaust end, these supports also being secured to the foundation.

Abstract: A gas-turbine plant of the air-storage type comprises a multi-stage gas-turbine having high and low pressure sections, a flow medium heating device located between the high and low pressure sections of the gas-turbine, a dynamoelectric machine coupled to the gas-turbine, a compressor also coupled to the dynamoelectric machine and an air-storage tank connected between the compressor outlet and the inlet to a heat exchanger heated by exhaust gas from the gas-turbine and through which the medium flows to the high pressure section of the gas-turbine.

Abstract: Apparatus for intermittently turning a turbine shaft wherein a ratchet wheel is secured upon the shaft and is engaged intermittently by a to and fro movement of a ratchet arm actuated by a reciprocating drive mechanism. The ratchet arm has a combined rectilinear and pivotal movement and is provided with a device, operable in the event the ratchet wheel is put into rotation by starting up of the turbine while the ratchet arm is engaged with the ratchet wheel, for detaining the arm against a return pivotal movement towards the ratchet wheel after being hurled outwardly therefrom to a predetermined position.
