Abstract: An automated EL CID inspection technique for the stator core of an electrical machine is provided. The inspection device includes a rail, a pickup coil and a coil support assembly. The coil support assembly includes a first part movable along the rail, and a second part where the pickup coil is actually installed. The second part is movable jointly with the first part along the rail, while also being movable relative to the first part in a direction towards or away from the stator core. A motor actuates a motion of the coil support assembly. During inspection, the motor is activated, upon which the coil support assembly moves along the rail while a specified distance is maintained between the stator core and the pickup coil by the relative motion between the first and second parts. The technique is particularly applicable in a step-iron portion of the stator core.

Abstract: A temporary rail system (12) is provided for installing a stator core (14) in a generator frame (16). The rail system includes rail assemblies (18, 20, 22, 24), where each rail assembly includes support pieces (19, 21, 23) axially positioned at a circumferential location (26, 28, 30, 32) along frame rings (34, 36, 38, 40, 42) of the frame. The rail assembly also includes fasteners (48) to secure the support pieces to the circumferential location. The rail assembly also includes lifting assemblies (52) positioned on each support piece, a support beam segment (62, 64) positioned on each lifting assembly, and a rail segment (66, 68) positioned on each support beam segment such that a rail (69) including the rail segments is axially positioned along the support pieces of the rail assembly.

Abstract: A solid oxide fuel cell generator (10) is made which contains bundles (14) of solid oxide fuel cells (36), a bus bar unit (128) in adjacent contact with the fuel cell bundles, where the bus bar unit (128) can pass electrical current, the bus bar unit (128) containing flat inner plate sections (130) adjacent the fuel cell bundles, outer solid nickel bar (134) and with solid, U-shaped nickel strap take-off connections (136) between the plates and bar; and a power lead (140) electrically connected to the outer solid nickel bar, where the flat inner plate sections (130) and solid U-shaped nickel strap take-off connections (136) pass electrical current generated in the fuel cell bundles through the bus bar units (128).

Abstract: A high temperature fuel cell generator (10) having a housing (12) containing a top air feed plenum (80), a bottom fuel inlet (54), a fuel reaction generator chamber (62) containing fuel cells (42) and a reacted fuel-reacted air combustion chamber (38) above the fuel reaction generator chamber (62), where inlet air (14) can be heated internally within the housing in at least one interior heat transfer zone/block (92) located between the reacted fuel-reacted air combustion chamber (38) and the air feed plenum (80).

Abstract: A solid oxide fuel assembly is made of fuel cells (16, 16′, 18, 24, 24′, 26), each having an outer interconnection layer (36) and an outer electrode (28), which are disposed next to each other with rolled, porous, hollow, electrically conducting metal mesh conductors (20, 20′) between the fuel cells, connecting the fuel cells at least in series along columns (15, 15′) and where there are no metal felt connections between any fuel cells.
