Published Papers, Patents and Books
I have had over 30 technical papers published on various bulk material handling topics from belt cleaners to vibrators to air cannons. Over 50 US patents and many corresponding foreign patents have been issued where I am a named inventor.  I have given numerous technical and training presentations around the world. I am the lead author of Martin Engineering’s FOUNDATIONS Book series on the practical control of fugitive materials in bulk material handling.  I am the editor of the 6th and 7th editions of The Conveyor Manufacturers Association Belt Conveyors for Bulk Materials book, “The CEMA Belt Book”.
