• 12:21, 10 January 2013 Martin Bolton talk contribs uploaded File:027SketchPortfolio UJ MartinBolton.JPG (027SketchPortfolio_UJ_MartinBolton Exploring the possibility of an "auto filling" solution, to maintain a level in the ceramic filter element. This would decrease the number of necessary fillings.)

This would suit warehousing, shipping, and distribution. However, it would be ...)
