US Patent:

59457830, Aug 31, 1999

Filed:

Jul 13, 1998

Appl. No.:

9/114617

Inventors:

William Newell Schultz - Niskayuna NY
Robert James Thomas - Rexford NY

Assignee:

General Electric Company - Schenectady NY

International Classification:

H05B 3702

US Classification:

315219

Abstract:

A CFL ballast includes complementary-type switching devices connected in series with their gates connected together at a control node. The switching devices supply a resonant tank circuit which is tuned to a frequency near, but slightly lower than, the resonant frequency of a resonant control circuit. As a result, the tank circuit restarts oscillations immediately following each zero crossing of the bus voltage. Such rapid restarts avoid undesirable flickering while maintaining the operational advantages and high efficacy of the CFL ballast.

US Classification:

361 13

Abstract:

A current limiting system for a circuit limits current flow through the system. The current limiting system comprises at least one main switch comprising first and second main switch contacts and a contactor connecting the first and second main switch contacts; at least one current limiting device and at least one solid-state switch, which are mechanically unconnected to the main switch, and the at least one current limiting device and least one solid-state switch are arranged in series on a series side of the circuit; the at least one main switch is on a main switch side of the circuit arranged in parallel with the series side; a control that senses a predetermined condition of the circuit, and operably connected with the at least one solid state switch to open and it. Under normal operating conditions, most current flows through the at least one main switch side. When the predetermined condition causes the main switch to open, and the resistance increases in a main switch side.

International Classification:

H01J 6136
H01J 6500
H01J 6124

US Classification:

315248

Abstract:

An electrodeless fluorescent lamp includes a feedthrough structure extending from the exterior to the interior of the lamp which is constructed of a suitable material, e. g. , platinum or a combination of platinum and rhodium, for directly connecting an interior EMI shield to ground. The feedthrough is also suitable for supporting an amalgam flag.

Assignee:

General Electric Company - Schenectady NY

International Classification:

C25D 1316
C25D 1312

US Classification:

2041811

Abstract:

A process for electrodepositing mica and a water soluble anionic resin binder, such as a modified polyester resin, is disclosed as a means for applying a heavy coating of a high-voltage, mica-bearing electrical insulation onto uninsulated and porous mica tape-insulated portions of electrical connections in dynamoelectric machines. The electrodeposited mica coating is subsequently impregnated with a suitable resin, such as an epoxy or polyester resin, concurrently with the impregnation of other conventional insulations in the machine. Alternatively, deposition and impregnation of the connection insulation can be performed prior to installing the connection into the machine.

Assignee:

General Electric Company - Schenectady NY

International Classification:

H02K 3487

US Classification:

310214

Abstract:

A stator core for a dynamoelectric machine includes two pairs of dovetail slots disposed at respective predetermined radial positions in each armature slot. All stator slots contain armature bars. A few equally spaced stator slots also contain "P" bars atop or radially inward from armature bars. Wedges are installed in the radially outer dovetail slots of stator slots containing only armature bars. Wedges are installed in radially inner dovetail slots in stator slots containing both armature bars and "P" bars.

Assignee:

General Electric Co. - Schnectady NY

International Classification:

H01B 902

US Classification:

174102SC

Abstract:

A semi-conducting pyrolyzed glass fiber layer equalizes the electrical potential on the exterior surface of an insulated conductor when the layer covers the surface. The layer prohibits the development of a corona discharge and bleeds off any electrical charge developed thereon when the layer is electrically coupled to a body having a known potential. The insulated conductor may be windings in a dynamoelectric machine.
