Assignee:

J. Ray McDermott, S.A. - Houston TX

International Classification:

F16N 1322

US Classification:

184 152, 184 153, 184 551

Abstract:

Lubrication devices for lubricating wire rope on a crane. Spray nozzles may be permanently mounted to the multi-sheaved wire block assemblies. A controller and oil supply located near the base of the crane are used to control and deliver oil to the spray nozzles. A telescopic spray unit is used to lubricate the vertical stationary wire rope. A crawler that rides on the wire rope is used to lubricate the stationary wire rope between the anchor point and the first sheave of the block assembly. Improved clamshell units are used to lubricate the wire rope between the drums storing wire rope and the first sheave.

Appl. No.:

12/577507

Inventors:

Thomas Edward Doyle - Louisville OH, US
Terry Louis Breaux - Houma LA, US
Clyde David Noel - Houma LA, US
Paul Berbakov - Coconut Creek FL, US

International Classification:

B23K 9/00

US Classification:

219136

Abstract:

A narrow groove GMAW torch for thick section welding that addresses the problems of conventional welding torches. A main body portion has a power block with electrical, feed welding wire, water cooling, and shielding gas connections and a contact tip. A dielectric is attached to the main body portion and has a primary shield gas outlet. A gas shield attached to the dielectric defines an annulus between them that functions as a secondary gas shield. A diffusing gas outlet in the dielectric delivers shielding gas to the weld area. The contact tip attached to the power block is designed to receive and control the curvature of the feed welding wire.

Appl. No.:

13/176848

Inventors:

Paul John Berbakov - Coconut Creek FL, US

International Classification:

B23K 9/28

US Classification:

219136

Abstract:

A pipe welding arrangement that allows for real-time independent control of all carriages, torches, and ancillary components by design. The invention uses a split-ring race that is mounted on a backing ring of similar design. Numerous welding heads are mounted on carriages that are distributed at set intervals along the circumference of the race. The left and right side race and backing ring assemblies are split at the twelve o'clock and six o'clock positions. They can be decoupled and spread apart horizontally to facilitate installation and for clearing obstacles. Alignment tools (tapered pins) facilitate assembly. Locking devices located near each split interface, coupled with the alignment pins, assure that the race acts as a continuous unit during the welding operation. Linear actuators mounted on the backing rings maintain concentricity between the race and the welded tube and act as a positive clamping system.

Appl. No.:

9/271742

Inventors:

Donald M. Stevens - Lovingston VA
Daniel T. MacLauchlan - Lynchburg VA
Paul J. Berbakov - Norton OH

Assignee:

McDermott Technology, Inc. - New Orleans LA

International Classification:

G01N 2918

US Classification:

73643

Abstract:

A method for detecting the location of an edge, interface, seam or other structure of a workpiece uses one or two electromagnetic acoustic transducers (EMATs) to transmit an ultrasonic wave along the workpiece toward the edge and to receive a reflected wave. The velocity of the wave in the material is used in conjunction with the round trip time-of-flight (TOF) of the transmitted and reflected wave, to calculate the location of the edge. This is done by placing the transducer or transducers at known locations on the workpiece. A surface wave or 90 degree shear wave can be utilized and no contact is needed between the transducer and the surface of the workpiece. Rough and/or dirty surfaces and hostile environments can be accommodated while practicing the invention.

Appl. No.:

6/301788

Inventors:

Paul J. Berbakov - Akron OH

Assignee:

The Babcock & Wilcox Company - New Orleans LA

International Classification:

B24B 1700
B24B 2116
B23Q 3500
B23K 710

US Classification:

51241S

Abstract:

A semiautomatic weld grinding apparatus for grinding the surface of a weld seam interconnecting two perpendicularly disposed tubular sections. The grinding apparatus is capable of grinding off excess weld from a saddle-type nozzle to shell weldment that follows a circular path through a plurality of planes. Alternatively, the apparatus is adaptable to function as a welding or a cutting apparatus that follows the saddle-shaped path created at the interface of two perpendicularly disposed tubular sections.

Assignee:

McDermott Technology, Inc. - New Orleans LA

International Classification:

B23K 9095

US Classification:

21913021

Abstract:

An automated process for inspecting and controlling the quality of titanium welds using color recognition. A color sensor and white light source are mounted to a fixture. The fixture is used to traverse the weld or the part being welded is moved in the viewing path of the sensor. The sensor is calibrated to indicate the desired or undesired color of a weld. A recording device such as a computer is used to receive signals from the sensor and record the location of weld colors that indicate an unacceptable weld. Weld parameters are controlled by color feedback to minimize the deposition of unacceptable weld.
