International Classification:

C23F 11/08
G01N 21/75

US Classification:

25238923, 252390, 436164

Abstract:

A method for inhibiting corrosion comprises the steps of providing a fluid; adding a corrosion inhibitor comprising at least one amphiphilic chemical to the fluid; and monitoring micelles presence in the fluid. A method for determining the amount of corrosion inhibitor that is sufficient to inhibit corrosion, a method for monitoring the activity of an amphiphilic chemical and a system for inhibiting corrosion in a conduit are also disclosed.

International Classification:

E21B 4700

US Classification:

73151

Abstract:

Strain gauges are attached to a drill pipe which is inserted into a drill pipe string to be used in a well. The strain gauges are connected to an electrical circuit containing devices for digitizing the electrical signals generated by the strain gauges in response to the detection of strain and for recording and retaining the digitized signals until the drill pipe string is extracted from the well. The electrical circuit provides a communication path through which the stored digitized data is transferred to an external device when the drill pipe string is extracted from the well.

Appl. No.:

6/267109

Inventors:

Michael W. Joosten - Ponca City OK

Assignee:

Conoco Inc. - Ponca City OK

International Classification:

B32B 1504
G01N 320
G01N 2904

US Classification:

73788

Abstract:

A damping device for use with acoustic information generation machines for isolating a generation portion of the generation device from contamination by extraneous acoustic emissions. A metal isolation piece consisting of a shape-memory alloy is disposed between an extraneous noise source and the generation portion of the device. Acoustic information generation devices in accordance with the present invention include phonograph record playing devices and testing devices for recording acoustic signals generated upon stressing a test piece. Thus, the present invention provides improved phonograph record playing devices and an improved testing device.

International Classification:

E02B 1700
C23F 1300

US Classification:

405211

Abstract:

A flame sprayed aluminum coating of high strength steel components offers excellent seawater corrosion protection, increased fatigue life and uniform low level cathodic protection that avoids hydrogen embrittlement. Marine mooring and riser elements fabricated from such components are superior in the above respects to steel components protected from corrosion by common sacrificial anode cathodic protection systems. In addition, the need of welding a stud to the steel to insure electrical continuity between the steel and the sacrificial anodes is eliminated.
