US Patent:

60298790, Feb 29, 2000
Filed:

Sep 23, 1997
Appl. No.:

8/936007
Inventors:

Elijah E. Cocks - Durham NC
International Classification:

B23K 2012
US Classification:

228 21
Abstract:

A friction-stir welding probe tip is disclosed which has right-handed threads on one portion of the probe and left-handed threads on another portion of the probe such that weld material is drawn to the middle of the weld as the friction-stir welding probe is rotated and passed along the joint region of the pieces to be joined. This probe tip is also fitted with a shoulder region for gripping by a rotation means.

Electrochemically Active Paint For Cathodic Protection Of Engineering Structures

US Patent:

53363035, Aug 9, 1994
Filed:

Sep 2, 1993
Appl. No.:

8/116223
Inventors:

Elijah E. Cocks - Durham NC
Assignee:

C-Innovations, Inc. - Research Triangle Park NC
International Classification:

C09D 508
US Classification:

106 1405
Abstract:

An electrochemically active paint is disclosed which provides cathodic protection to metallic materials of construction. This paint incorporates high concentrations of conductive pigment materials in combination with both corrosion inhibiting agents and exceptionally active metal pigments that can cathodically protect the base metal to which the paint is applied even though the metal pigment particles are incorporated within the paint vehicle. Applying this paint to an engineering structure confers active cathodic protection, and the resulting painted structure is thus rendered completely immune to corrosion for the active lifetime of the paint.
