Scope and content
This series documents Etkin’s research activities relating to Infrasizer Ltd.. This company was founded in 1937 by University of Toronto mining professor H.E.T. Haultain as a means of building and distributing his Infrasizer, a particle separator that he invented for use in processing minerals. When Etkin became Dean of Engineering in 1973, he became the defacto president of Infrasizer Ltd. Files at the beginning of this series contain mainly correspondence and reports relating the administration of Infrasizer Ltd during Etkin’s period as Dean (1973-1979).
While in his capacity as director of the company, he set out to improve on the model. The result was the Infrasizer MK III a laboratory device and the Tervel Separator developed for commercial use. Most of the records in this series document the development of these two inventions. Includes information on patents and use of the MK III model for industry clients (filed alphabetically by client name) as well as the attempt to manufacture and market the Tervel Separator.
