Appl. No.:

13/842877

Inventors:

LINCOLN GLOBAL, INC. - City of Industry CA, US
Steven R. Peters - Huntsburg OH, US

Assignee:

LINCOLN GLOBAL, INC. - City of Industry CA

International Classification:

B23K 26/20
B23K 9/00

US Classification:

21912163

Abstract:

A system and method of hybrid welding a dual fillet weld. The system includes a laser system that leads a first torch and preheats at least one workpiece. The system also includes a first welding power supply that supplies a first welding waveform to a first wire via the first torch. The first welding waveform creates a first arc between the first wire and the at least one workpiece. The system further includes a second welding power supply that supplies a second welding waveform to a second wire via a second torch. The second welding waveform creates a second arc between the second wire and the at least one workpiece. A controller in the system is operatively coupled to the first power supply, the second power supply and the laser system. The controller synchronizes the first welding waveform and the second welding waveform such that welding current pulses of the second welding waveform at the second torch are not in phase with welding current pulses of the first welding waveform at the first torch. The system is set up such that the first arc and the second arc are across from each other on opposite sides of a weld.

International Classification:

G01S 1308

US Classification:

342128

Abstract:

A microwave transceiver using a reflection pumped mixer includes an electromagnetic signal generator, a subreflector, a reflector of electromagnetic signals from the subreflector, a mixer, circulator, and processing circuitry to relate electromagnetic signal frequency differences to the range of a target from the transceiver. Such frequency differences are detected by the mixer from the captured electromagnetic signals reflected distant targets and reflected electromagnetic signals from the subreflector.

Assignee:

The Boeing Company - Seattle WA

International Classification:

H01Q 21280
G01S 13870

US Classification:

343720

Abstract:

A coaxial multiple-mode antenna system (10) is disclosed, including a coaxial input section (14) for coaxially collecting, for example, MMW and IR electromagnetic radiation. The IR radiation is focused to a point at the input section's focal plane, while the MMW beam has a relatively large width in this plane. An interface section (16) includes an IR section (18) and MMW section (20) that allow the two beams to be separately processed with a minimum of losses. In that regard, the MMW section includes a lens (42), having an incident surface, the center of which is positioned at the focal plane. An optical fiber (46) extends axially through the lens and has an incident end that is aligned with the incident surface of the lens. The lens quasi-optically transmits the MMW beam to a detection circuit (26), while the optical fiber transmits the IR beam to detection circuit (22). Because the optical fiber receives the IR beam before it is processed by the lens, IR losses are limited.

Appl. No.:

Inventors:

Steven J. Peters - Renton WA

Assignee:

The Boeing Company - Seattle WA

International Classification:

H01Q 1302

US Classification:

343777

Abstract:

An electronically tunable phased array antenna element compensates for the variation of input impedance as the scan angle of the array changes. A microstrip feed is used which allows monolithic microwave integrated circuits to easily be incorporated in the radiating element housing. The element improves transmit or receive sensitivity. In addition, this electronic tuning will counteract detuning of the element caused by external influences such as electromagnetic field coupling from other nearby antennas.

Assignee:

The Boeing Company - Seattle WA

International Classification:

H01P 116

US Classification:

333 21A

Abstract:

A nearly square waveguide below cutoff has a microstrip substrate disposed diagonally therein. A first shunt capacitance is provided by either a conductor formed on the microstrip substrate or a conductor disposed in the waveguide perpendicular to the microstrip substrate. A dielectric window is disposed in the end to provide a shunt capacitance at the opposite end of the waveguide.

International Classification:

Abstract:

An electric arc welder and a method for performing a pulse welding process producing reduced spatter. The welder produces a current between an advancing electrode and a workpiece. The welder includes a short-detecting capability for detecting a short condition upon occurrence of a short circuit between the advancing electrode and the workpiece. The welder may also include a switching module in the welding circuit path of the welder having an electrical switch and a resistive path. Times of occurrence of short intervals can be tracked and a blanking signal can be generated based on the tracked short intervals to anticipate a next short interval in a next pulse period of the pulsed welding process. The blanking signal can be used to reduce a welding current in the welding circuit path by introducing additional resistance into the welding circuit path via the switching module, for example.
