Abstract: A steam turbine-driven generator for generating electric power is comprised of an electric generator having a vertical shaft journalled for rotation between bearings contained in a generator housing. An axial flow impulse turbine wheel with peripheral vanes is secured to an unsupported upper end of the shaft protruding from the top of the generator housing. The turbine wheel is enclosed within a turbine housing secured to the top of the generator housing. The turbine housing includes an inlet and an outlet for accommodating a through flow of steam, with internally arranged nozzles for directing the steam flow against the vanes of the turbine wheel.

Abstract: A reaction-type fan has a housing with a central collar rotatably supporting a hub having blades extending radially therefrom. Nozzles are carried at the tip portions of the blades. Compressed air is directed through the housing, collar, hub and blades to the nozzles. The nozzles are arranged such that the reactive force of the compressed air exiting therefrom rotates the blades, thereby causing ambient gases to be drawn through the housing. Sound absorbing elements are positioned along the flow path of the compressed air to attenuate noise associated therewith.
