Abstract
Abstract A carrying structure has a wall which defines a duct. A central structure comprising an axial-flow turbine and a generator is disposed in said duct. At least two radial arms, which are substantially horizontal, are rigidly fixed to said wall and hinged to said central structure.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
97 words
In a power plant which comprises (1) a carrying structure having a wall defining a duct having an axis, (2) a central structure comprising an axial-flow turbine and a generator, (a) the central structure being disposed substantially coaxially in the duct, and (3) a pair of radial arms rigidly fixed to the wall and extending diametrically and substantially perpendicularly to the axis, on a horizontal plane, the improvement of (4) hinge means connecting each of the arms to the central structure for pivoting the central structure about an axis substantially parallel to the axis of the duct.
Claim 2
Dependent Claim
97 words
In a power plant which comprises (1) a carrying structure having a wall defining a duct having an axis, (2) a central structure comprising an axial-flow turbine and a generator, (a) the central structure being disposed substantially coaxially in the duct, and (3) a pair of radial arms rigidly fixed to the wall and extending diametrically and substantially perpendicularly to the axis, on a horizontal plane, the improvement of (4) hinge means connecting each of the arms to the central structure for pivoting the central structure about an axis substantially parallel to the axis of the duct.
Claim 3
Dependent Claim
42 words
In the power plant defined in claim 1, the hinge means comprising a bearing member affixed to the central structure and having a cylindrical surface, and a bearing shell affixed to the arm and embracing the cylindrical surface of the bearing member.
Claim 4
Dependent Claim
27 words
In the power plant defined in claim 1, two of said pairs of radial arms, the pairs of arms being spaced along the axis of the duct.
Claim 5
Dependent Claim
15 words
In the power plant defined in claim 1, the arms being integral with the wall.
Claim 6
Dependent Claim
102 words
In a power plant which comprises (1) a carrying structure having a wall defining a duct having an axis, (2) a central structure comprising an axial-flow turbine and a generator, (a) the central structure being disposed substantially coaxially in the duct, and (3) a pair of radial arms rigidly fixed to the wall and extending diametrically and substantially perpendicularly to the axis, on a horizontal plane, the improvement of (4) hinge means comprising a resilient connecting member connecting each of the arms to the central structure for pivoting the central structure about an axis substantially parallel to the axis of the duct.
Claim 7
Dependent Claim
102 words
In a power plant which comprises (1) a carrying structure having a wall defining a duct having an axis, (2) a central structure comprising an axial-flow turbine and a generator, (a) the central structure being disposed substantially coaxially in the duct, and (3) a pair of radial arms rigidly fixed to the wall and extending diametrically and substantially perpendicularly to the axis, on a horizontal plane, the improvement of (4) hinge means comprising a resilient connecting member connecting each of the arms to the central structure for pivoting the central structure about an axis substantially parallel to the axis of the duct.
Claim 8
Dependent Claim
87 words
In the power plant defined in claim 5, the resilient connecting member being a diaphragm having a rim and a central portion, the diaphragm extending substantially parallel to the axis of the duct and the rim being ridigly connected to the arm, the central structure carrying a radial bracket substantially coaxial with the arm and rigidly connected to the central portion of the diaphragm, and the central portion carrying a crowned pad substantially coaxial with the arm and the bracket, the crowned pad bearing on the arm.
