US Patent:

46200860, Oct 28, 1986

Filed:

Sep 30, 1985

Appl. No.:

6/781380

Inventors:

Adrian R. Ades - Schenectady NY
Paul B. Pribis - Saratoga NY
Donald J. Proach - Rotterdam NY

Assignee:

General Electric Company - Schenectady NY

International Classification:

H05B 310
H01B 700
H01C 102
B05D 302

US Classification:

219552

Abstract:

To reduce the tendency of ground faults and short circuits on electrical heating elements operating at elevated voltages and temperatures, resistance heating wire is coated with a sublayer of magnesium zirconate followed by an outer layer of aluminum oxide; each layer being in the range of 0. 001 to 0. 010 inches thick.

Appl. No.:

6/491509

Inventors:

Adrian R. Ades - Schenectady NY

Assignee:

General Electric Company - Schenectady NY

International Classification:

B23P 1900
B23P 1102

US Classification:

29800

Abstract:

A turbine rotor disassembly, handling and reassembly apparatus employs a feedback-controlled electric heating oven to rapidly heat a turbine wheel while the rotor shaft is in the horizontal position. An adapter interfaces the wheel to a handling spool whose outboard end is adjusted to slide on the rotor shaft and to provide a fulcrum for supporting the wheel. A handling trolley includes a soft hydraulic system for supporting the weight of the wheel to avoid damaging the precision machined surfaces of the shrink-fit area while the wheel is being withdrawn. The handling apparatus also provides means for upending, or rotating, the removed wheel through 90 degrees to place its axis vertical for facilitating handling. A sensor system senses a radial motion of the wheel to detect clearance and to establish an appropriate fluid pressure to just balance the weight of the wheel and attached parts. The handling system includes means for rotating the wheel slightly during reassembly to align keyways or the like.
