  • High efficiency metal pigments
    Patent number: 5874167
    Abstract: Thin film metal particulates are removed from FEP sheetstock cheaply and quickly by immersing the coated FEP first in a base and then in an acid. Occasionally, ultrasonic vibration of the FEP may also be required. The particulates are useful as paint pigments when isolated and conversion coated. The FEP is reusable.

  • Expendable ceramic mandrel
    Patent number: 5226470
    Abstract: Expendable mandrels and methods of using such mandrels for forming voids within materials or surfaces on materials deposited onto the mandrels are described. The mandrels have a coefficient of thermal expansion that substantially matches that of the material to be deposited on the mandrel. Matching coefficients of thermal expansion reduces the likelihood of cracking of the base material when the mandrel and base material are cooled.
