Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 153 words
In combination, a rotating electrical device, a rotating fuse means, said rotating fuse means comprising one or more fuse assemblies (12), end terminal connectors (17, 18) disposed at the ends of each fuse assembly (12), each fuse assembly (12) comprising an insulating casing with an interiorly-disposed longitudinally-arranged insulating support-plate means (27) and a generally parallel-arranged fuse-link (23), means affixing said fuse-link (23) to the longitudinally-arranged insulating supportplate means (27), said support-plate means (27) being supported by said end terminal connectors (17, 18) for the rigid support thereof, means for in effect providing a common shaft carrying said rotating electrical device and said rotating fuse means, circuit means carried by said shaft for electrically connecting said electrical device and said rotatable fuse means together, means locating said fuse casing and said support-plate means (27) in a radial direction with respect to said shaft, and indicating means for indicating operation of the rotating fuse means.
Claim 2
Dependent Claim 153 words
In combination, a rotating electrical device, a rotating fuse means, said rotating fuse means comprising one or more fuse assemblies (12), end terminal connectors (17, 18) disposed at the ends of each fuse assembly (12), each fuse assembly (12) comprising an insulating casing with an interiorly-disposed longitudinally-arranged insulating support-plate means (27) and a generally parallel-arranged fuse-link (23), means affixing said fuse-link (23) to the longitudinally-arranged insulating supportplate means (27), said support-plate means (27) being supported by said end terminal connectors (17, 18) for the rigid support thereof, means for in effect providing a common shaft carrying said rotating electrical device and said rotating fuse means, circuit means carried by said shaft for electrically connecting said electrical device and said rotatable fuse means together, means locating said fuse casing and said support-plate means (27) in a radial direction with respect to said shaft, and indicating means for indicating operation of the rotating fuse means.
Claim 3
Dependent Claim 168 words
In combination, a synchronous alternating-current machine having a rotating field winding, exciter means having a rotating armature winding, a rotatable fused rectifier assembly having one or more fuse assemblies, end terminal connectors (17, 18) disposed at the ends of each fuse assembly (12), each fuse assembly (12) comprising an insulating casing with an interiorly-disposed longitudinally-arranged insulating support-plate means (27) and a generally parallel-arranged fuse-link (23), means affixing said fuse-link (23) to the longitudinally-arranged insulating supportplate means (27), said support-plate means (27) being supported by said end terminal connectors (17, 18) for the rigid support thereof, means for in effect providing a common shaft carrying the rotating field winding, said rotatable fused rectifier assembly and the rotating armature winding, means locating the one or more fuse casings and the support-plate means (27) of the rotatable fused rectifier assembly in a radial direction with respect to the shaft, and circuit means for electrically connecting said rotatable fused rectifier assembly to the rotating armature winding and to the rotating field winding.
Claim 4
Dependent Claim 168 words
In combination, a synchronous alternating-current machine having a rotating field winding, exciter means having a rotating armature winding, a rotatable fused rectifier assembly having one or more fuse assemblies, end terminal connectors (17, 18) disposed at the ends of each fuse assembly (12), each fuse assembly (12) comprising an insulating casing with an interiorly-disposed longitudinally-arranged insulating support-plate means (27) and a generally parallel-arranged fuse-link (23), means affixing said fuse-link (23) to the longitudinally-arranged insulating supportplate means (27), said support-plate means (27) being supported by said end terminal connectors (17, 18) for the rigid support thereof, means for in effect providing a common shaft carrying the rotating field winding, said rotatable fused rectifier assembly and the rotating armature winding, means locating the one or more fuse casings and the support-plate means (27) of the rotatable fused rectifier assembly in a radial direction with respect to the shaft, and circuit means for electrically connecting said rotatable fused rectifier assembly to the rotating armature winding and to the rotating field winding.
