Alexander Harrison, Founder of Conveyor Technologies Ltd LLC (CTL), is based in Denver, Colorado, USA (see [] and A Harrison). Dr. Harrison was born in Australia and moved to the USA in 1991.

Prior to that time while working at CSIRO, technology was developed by Harrison (US Patent 4,439,731) to scan steel cable and fabric reinforced conveyor belts used worldwide in the mining industry. The scanning process involved non-contact non-destructive testing (NDT) using magnetic and electromagnetic fields to detect belt reinforcing members. Harrison became a Principal Research Scientist at CSIRO (Commonwealth Scientific Industrial Reserarch Organisation)and then held the MERZ/TUNRA Chair in Mechanical Engineering at Newcastle University in Bulk Solids Handling and Conveying. Problems involving non-linear vibrations and proof of chaotic dynamics in large belts has been published widely by Harrison. The mathematics and physics of non-linear vibrations in running belts was published in the Phil. Transactions of the Royal Society London in the 90's.

Conveyor system engineering and design, as well as remote NDT of belts, occupies a large part of the ongoing research and development of CTL.
