Abstract: A corrosion prevention survey system for determining locations of faults along an underground structure includes a data collector to record location data and voltage data; a voltage reading system to secure to a leg of a user, the voltage reading system having a pole with a spike to be inserted into a ground surface, the spike being able to read a voltage current running through the ground; an attachment device to secure the pole to the leg of a user; and one or more wires to connect the pole to the data collector; the pole is a predetermined length not greater than 2 feet; the voltage data is transmitted from the pole to the data collector; and the location data and voltage data are used in analysis to determine directions of voltage gradients for further determination of location of faults along the underground structure.

Abstract: A laced wheel manufactured from a one-piece casting, including both the hub portion and the rim portion. After casting and machining spoke interfaces, the hub and rim portions are separated and wire spokes are assembled.

Abstract: A ferrule arrangement for use in sealing connections to gas chromatography columns includes a generally tubular metal ferrule with an axial bore to receive a fracturable column with a protective coating. The ferrule has a forward part that tapers to a tip region of the ferrule. A generally tubular former has a socket portion to receive the ferrule and further has an internal conical surface that, after such receipt, engages the forward part of the ferrule. A portion is provided on either or both of said ferrule and the former by which the ferrule and former may be directly or indirectly relatively moved together by application of finger force.
