Filed:

Apr 1, 2004

Appl. No.:

10/815593

Inventors:

Steven Hansen - Port Washington WI, US
Charles Check - Mequon WI, US

International Classification:

B41J002/435

US Classification:

347/224000

Abstract:

A laser marking/imaging system including a passively Q-switched microlaser having a saturable absorber which upon reaching an energy threshold emits a pulse of light through an optical output. The microlaser is electrically connected to circuitry which provides power to the microlaser, and has a simmer mode and a lasing mode. In the simmer mode, power provided to the microlaser is maintained at an energy level below the energy threshold, and in the lasing mode, power provided to the microlaser raises the energy level of the microlaser above the energy threshold. A guidance mechanism can direct the pulse of light from the optical output along a path toward an image receiving target when the microlaser is in the lasing mode.

Appl. No.:

8/113009

Inventors:

Steven D. Hansen - Port Washington WI

Assignee:

General Electric Company - Milwaukee WI

International Classification:

H01J 3510

US Classification:

378131

Abstract:

The motor efficiency of a rotating X-ray tube having an anode assembly and a cathode assembly, can be greatly improved. The improved efficiency x-ray tube motor comprises a stator and rotor assembly having an air gap between the stator and rotor. The improved efficiency is achieved by reducing the air gap. The stator is operated at anode potential and electrically connected through an anode high voltage cable.

Appl. No.:

7/405687

Inventors:

International Classification:

F02D 4104
F02P 515

US Classification:

123425

Abstract:

A detonation control system for a fuel injected, spark ignition two-cycle engine utilizes a linear series of engine knock signals and a programmable microprocessor to provide a non-linear series of stepped increases in the fuel injection pulse width to the engine effective to substantially reduce or eliminate engine knock. If desired or necessary, the system may also be utilized to provide a non-linear series of stepped increases in spark ignition retard to further reduce or eliminate engine knock. The non-linear stepped increases in the control parameters have been found to effectively control detonation without adversely affecting engine performance and efficiency.

General Electric Company - Milwaukee WI

International Classification:

H02K 1900

US Classification:

310261

Abstract:

An induction motor rotor particularly for x-ray tube applications comprises a series of hollow cylinders fitting concentrically on each other and on a motor shaft. The first cylinder is a highly heat resistant and electrically insulating material. The next cylinder is a highly magnetic material cylinder fitting on the first cylinder. The next and outermost cylinder is an electrically conductive material providing the armature conductor of the induction motor rotor.

International Classification:

F01P 1116
F01M 120
F02B 7708

US Classification:

123 4115

Abstract:

In a marine drive having a wiring harness (14) connected between the engine (2) and the helm (8), an alarm sensing module (26) is connected to the harness (14) and provides a warning of one or more abnormal engine conditions, without altering the existing wiring harness or adding wires thereto. A temperature switch (30) and an oil pressure switch (32) are provided at the engine, and the sensing module (26) is connected to the engine temperature gauge (10) and engine oil pressure gauge (12) at the helm. The module activates an alarm (28) in response to high engine temperature or low engine oil pressure.

Abstract:

An x-ray generating device having an improved high efficiency motor is disclosed. The x-ray generating device comprises a cathode assembly and an anode assembly arranged opposite each other in a vacuum vessel. According to the invention, the anode assembly is coupled and rotated by the rotor of a high efficiency motor which has near traditional gaps by positioning the motor stator assembly in close proximity to the rotor of the motor and applying a same potential to both the stator core and the rotor. The stator assembly further includes poly-phase stator winding coils arranged on the stator core. The coils are electrically insulated from the stator core, and they are supplied with poly-phase AC signals from a motor controller to induce magnetic interactions and rotate the rotor and the anode assembly. Thus, the present invention provides for electrical isolation between the x-ray operating potential and the reference potential of the motor controller without the need for a separate isolation transformer which negatively impacts cost, efficiency and reliability.
