Arc Welding Torch With Integral Vision Sensor

View page
US Patent:
44880324, Dec 11, 1984
Filed:
Jun 11, 1984
Appl. No.:
6/619432
Inventors:
Allen W. Case - Amsterdam NY
Norman R. Kuchar - Burnt Hills NY
Donald C. Peroutky - Schenectady NY
Assignee:
General Electric Company - Schenectady NY
International Classification:
B23K 910
US Classification:
21912434
Abstract:
A gas tungsten arc welding torch has an integral optical system which images the weld puddle on the face of a fiber optic cable, and is suitable for industrial welding. The copper torch body has cover gas, electrical power, and coolant connections and an integral slim profile electrode holder. The optical lens is located directly above the electrode; the holder is out of focus and is not seen in the image of the weld region. A concentric torch configuration is more compact and has a large field of view at the weld area. When coupled to a remote video camera and monitor components, the torch-vision system permits control of torch manipulation and of the weld process.

Temperature Control Of A Solid State Face Pumped Laser Slab By An Active Siderail

View page
US Patent:
48521094, Jul 25, 1989
Filed:
Dec 2, 1988
Appl. No.:
7/278997
Inventors:
Norman R. Kuchar - Burnt Hills NY
Assignee:
General Electric Company - Schenectady NY
International Classification:
H01S 3045
US Classification:
372 34
Abstract:
Optical and thermal distortion in a solid state slab geometry laser are controlled by active siderails disposed at the lateral surfaces of the slab. Each siderail may have a fluid passage therethrough and be connected in a separate fluid circuit which enables the volumetric flow rate and temperature of the fluid through the passageway to be controlled in order to control the temperature of the siderail and, accordingly, the temperature of the slab in regions proximate to the siderail. The invention enables compensation of asymmetric transverse gradients to afford a uniform transverse temperature distribution.

Method Of Testing The Integrity Of Installed Rock Bolts

View page
US Patent:
40622290, Dec 13, 1977
Filed:
Feb 22, 1977
Appl. No.:
5/770697
Inventors:
David E. Godfrey - Burnt Hills NY
Norman R. Kuchar - Burnt Hills NY
Assignee:
General Electric Company - Schenectady NY
International Classification:
G01N 2900
US Classification:
73 88F
Abstract:
The bond integrity of resin grouted rock bolts or roof bolts anchored within the ceiling in underground mines is tested by inducing broadband vibrations and measuring the resonant frequencies of the axial and transverse vibration modes. Voids in the resin grout or imperfect bonding cause shifts in the resonant frequencies. The tension in expansion nut rock bolts is determined from the resonant frequency of the transverse vibration mode.

Solid State Laser Gain Medium With Diamond Coating

View page
US Patent:
48993476, Feb 6, 1990
Filed:
May 11, 1989
Appl. No.:
7/350265
Inventors:
Norman R. Kuchar - Burnt Hills NY
Farzin H. Azad - Clifton Park NY
Assignee:
General Electric Company - Schenectady NY
International Classification:
H01S 300
US Classification:
372 33
Abstract:
A laser gain medium has a diamond coating in order to strengthen it and reduce parasitic oscillations. The medium can be a slab with chamfered corners with the coating on the edge faces and the corners, or a rod with the coating going all the way around it to eliminate stress corrosion and provide a compressive stress. The medium can be Nd:YAG and the coating can have a parasitic absorbing dopant. In a laser, the length of the coating preferably is the same as the length of the medium. For the slab, siderails can be used with a length slightly shorter than that of the coating.
