Kenneth John Beer owns a few private companies in Perth that are into pressure-related technology – piping, storage cylinders, tanks, and pressure-related gadgets. The main business may be K J Beer Pty Ltd - see http://kjbeer.com.au/
KJB lives in Baramba Road, City Bach, and is the MD of Fort Baramba Pty Ltd, ACN 009 017 574, which is the same ACN as for K J Beer Pty Ltd. The two names seem to be alternatives for the same business.
Engineered Process Systems Pty Ltd has a different ACN, 009 341 968, but it is closely related to K J Beer Pty Ltd in terms of address, management and core technology. Why it exists with a separate ACN, I cannot say. It may be a small fabrication arm of what is essentially an engineering consultancy business.
Mr Beer showed up in the top-20 sharesholders list of FY2010, and I imagine that he knows BYL well, so on balance, that is a tick in the box.
