International Classification:

H01J 3502

US Classification:

378121, 378125, 378143

Abstract:

An X-ray tube assembly includes an anode, a cathode, and an X-ray transparent window. The anode includes an X-ray-producing target having a surface. The cathode has an electron-beam axis which intersects the target surface at a focal point and which is oriented at a first angle, with respect to the target surface, wherein the first angle is generally twenty degrees. The window includes a surface having a center point. A line between the focal and center points makes a second angle, with respect to the target surface, wherein the second angle is generally seven degrees. A method for producing X-rays employs these angles.

Assignee:

General Electric Company

International Classification:

H02J 500

US Classification:

307 66, 307 91

Abstract:

A power system for a locomotive generally having an internal combustion engine coupled to drive a main alternator and an auxiliary alternator is provided. The main alternator is coupled to power one or more traction motors and the auxiliary alternator is coupled to power predetermined electrical equipment. The system includes a main power bus generally powered by the main alternator and an auxiliary power bus generally powered by the auxiliary alternator. A power interface unit is electrically coupled to the main power bus to capture and transfer electrical energy into the auxiliary power bus. The electrical energy may be generated during a predetermined mode of operation of the locomotive, such as during dynamic braking or self-load.

International Classification:

H02K 1300

US Classification:

310143, 310144

Abstract:

An assembly for transferring current comprises at least one electrically conductive slip ring; at least one electrically conductive brush for supplying current to the at least one slip ring; and an electric or pressure actuator driven vibration source for changing the position of the brush with respect to the slip ring. If desired, brush current can shared by using inductance variations or by selective coupling of rotor windings to the slip rings.

Assignee:

International Classification:

H02K 112

US Classification:

310254, 29596

Abstract:

A dynamoelectric machine includes a stator having teeth fabricated from a non-magnetic material and containing at least one embedded conductor. The teeth are unitary with a back portion that is mounted to a stator back iron. Permeance variations induced by a stator winding mounted on the non-magnetic stator teeth are low which facilitates a reduction of motor noise. Specifically, since the non-magnetic teeth reduce production of permeance variations, changes in air gap forces between the rotor and the stator are decreased.

US Classification:

290 40C, 290 4 A, 290 4 B, 290 4 C, 290 4 R

Abstract:

A hybrid energy system for propelling an off-highway vehicle includes an engine rated at a first power capacity, and a power converter driven by the engine for providing primary electric power. A traction motor system receives the primary electric power, the traction motor system propelling the off-highway vehicle in response to the primary electric power, and the traction motor system further including a dynamic braking mode of operation. An energy storage medium captures electrical energy generated by the traction motor system in the dynamic braking mode of operation, the energy storage medium transferring a portion of the captured energy to the traction motor system to augment the primary electric power, wherein the traction motor system is rated at a second power capacity exceeding the first power capacity.

International Classification:

H02J 7/00

US Classification:

320104

Abstract:

A method for equalizing a storage parameter for a vehicle energy storage system having one or more energy storage banks associated therewith includes identifying a quiescent period of operation for the vehicle, and determining whether the value of a defined storage quantity for a first energy storage bank differs from the value of the defined storage quantity for a second energy storage bank by a threshold amount. During the quiescent period of operation, one of the first and second energy storage banks is discharged and the other of the first and second energy storage banks is charged. The one of the first and second energy storage banks corresponds to the bank having the value of the defined storage quantity exceeding the value of the defined storage quantity of the other of the first and second energy storage banks.
