Filed:

Jun 6, 2000

Appl. No.:

9/588862

Inventors:

Gregory J. Saxton - Gresham OR
Andrew A. Baker - Portland OR

Assignee:

Gunderson, Inc. - Portland OR

International Classification:

B61D 308
B61D 1704
B62D 2702

US Classification:

105355

Abstract:

A structural assembly defining a corner of a doorway for a railway boxcar in which a square-cornered doorway opening is provided and yet stress concentrations are avoided. A corner connecting member interconnects upright and horizontal doorway frame structures, but instead of including an angular intersection of vertical and horizontal surfaces defining the doorway opening, the corner member includes an arcuate concave connecting surface extending between the upright and horizontal surfaces defining the doorway opening. The arcuate concave connecting surface is located outside the doorway opening and extends around the location where the vertical and horizontal surfaces would intersect, so that there is no angular intersection to concentrate stresses. An insert fits matingly along the arcuate concave connecting surface and has an inside corner defined by surfaces that are located to extend the vertical and horizontal surfaces and define the corner of the doorway opening. The insert is held in place by a single fastener that avoids concentration of stresses in the insert.

Abstract:

A cable is used for running a load between surface and downhole in a well. The cable includes one or more wires composed of a non-metallic material. Each of the one or more wires bears the load from the surface and can electrically conduct between the surface and downhole. An insulating material is disposed about the one or more wires and insulates the electrical conduction. The non-metallic material includes a carbon nanotube wire. A jacket can be disposed about the insulating material, and the jacket can be composed a non-metallic material also, such as carbon nanotube wire. Markers disposed at predefined distances along the length of the cable are used to determine the deployed length of the cable.
