SPIROL
THE ADVANTAGES OF USING EDGE BONDED SHIMS the faces between mating components, cutting down the required machining time during rebuilds / retrofitting. Laminated Shims have peelable layers of metal which are removed until the Shim has the proper thickness. They are built up from layers of precision gauge metal foil. Layers are bonded into a rigid structure that appear and function as a solid sheet or plate. Adjusting them is as easy as peeling off laminations with a knife, or in the case of some materials, using no tool at all. Rather than...

Final Report: Barium Titanate/Polymer Nanoscale Composites with Controllable Architectures, September 2, 1998 - April 8, 1999
Since the films were cast on stainless steel shim stock , only top electrodes needed to be added. … electrodes were deposited by vacuum metal evaporation to establish the second contact required for material properties characterization. The dielectric properties of polystyrene-polybutadiene films were tested in one of six conditions: 1) as cast, 2) cast and annealed, 3) cast with added titanium alkoxide, 4) cast with added titanium alkoxide and annealed, 5) cast with added titanium alkoxide …
