Method for timing a polymer pump containing polymer
 
Moldt and Everitt of Equistar Chemicals, Texas, developed a method for restoring the registry of opposed shafts that carry meshing pump teeth inside a polymer pump that contains polymer without removing polymer from within the pump, the method using an asymmetric pattern of apertures in the shaft ends and a template having a pattern of holes that matches the pattern of apertures, and dowels that closely fit the holes and apertures.
